Detailed Description
Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and intended for the purpose of explaining the present application and are not to be construed as limiting the present application.
The following describes a sleep method and device of a vehicle-mounted controller and a vehicle according to embodiments of the present application with reference to the accompanying drawings. Aiming at the problems that when the vehicle-mounted controller encounters a wake-up device to send out a wake-up command in the sleep process, the sleep mode cannot be exited and data abnormality easily occurs when the vehicle-mounted controller is restored to a normal working mode from the sleep mode, the application provides a sleep method of the vehicle-mounted controller. Therefore, the problem that the vehicle-mounted controller cannot exit from the sleep mode and is easy to generate data abnormality when the vehicle-mounted controller returns to the normal working mode from the sleep mode when the wake-up device sends a wake-up instruction in the sleep process in the related technology is solved, the vehicle-mounted controller can be returned to the normal working mode in the sleep execution process, the situation that the normal working mode cannot be restored when the wake-up source sends the wake-up instruction in the sleep process of the vehicle-mounted controller is avoided, and the execution efficiency is increased.
Specifically, fig. 1 is a flow chart of a sleep method of a vehicle-mounted controller according to an embodiment of the present application. As shown in fig. 1, the sleep method of the vehicle-mounted controller includes the following steps:
in step S101, when the duration of non-working of the vehicle-mounted controller reaches a first preset duration, it is detected whether a first wake-up instruction sent by a first wake-up device is received.
The first preset duration may be a duration preset by a user, may be a duration acquired through limited experiments, or may be a duration acquired through limited computer simulation, which is not limited herein, and the first wake-up device may be an external hardware device, that is, an external hardware device that is not connected to the vehicle-mounted controller through the CAN (Controller Area Network, a controller area network), and the first wake-up instruction is a wake-up instruction sent by the external hardware device when a high level occurs (that is, a wake-up instruction sent by all wake-up devices except the CAN).
It should be understood that the vehicle-mounted controller continuously consumes the electric quantity of the low-voltage power supply when the vehicle-mounted controller is in low voltage for a long time, so that the low-voltage power supply is under-voltage, and therefore, when the vehicle is not operated for a long time (i.e. the non-operating duration of the vehicle-mounted controller reaches the first preset duration), the vehicle-mounted controller can detect whether the first wake-up instruction sent by the first wake-up device is received, and detailed description is omitted for avoiding redundancy.
In step S102, if the first wake-up instruction is not received, the vehicle-mounted controller is controlled to enter a pre-sleep mode, and when the vehicle-mounted controller is in the pre-sleep mode, whether a second wake-up instruction sent by the first wake-up device is received or not is detected every second preset time length.
Optionally, in some embodiments, when the vehicle-mounted controller is in the pre-sleep mode, performing sleep processing on the second execution data of the vehicle-mounted controller, and storing the processed second execution data; the second execution data is mainly state data (such as current electric quantity, capacitance, vehicle mileage and the like) of the vehicle.
The second preset duration is a duration preset by a user, may be a duration obtained through limited experiments or a duration obtained through limited computer simulation, is not particularly limited herein, and the second wake-up instruction is the same as the first wake-up instruction and is sent by the first wake-up device.
Specifically, if the second wake-up instruction sent by the first wake-up device is not detected, the vehicle-mounted controller CAN be controlled to enter a pre-sleep mode, at this time, the vehicle-mounted controller closes the CAN transmission to prevent other controllers of the whole vehicle from being affected by the message and being unable to sleep, and when the vehicle-mounted controller is in the pre-sleep mode, the vehicle-mounted controller detects whether the second wake-up instruction is received every second preset time length, for example, 5 s.
In step S103, when the in-vehicle controller receives the second wake-up instruction, the in-vehicle controller is controlled to switch from the pre-sleep mode to the pre-wake-up mode, and after the first execution data of the in-vehicle controller is restored, the pre-wake-up mode is ended, and the in-vehicle controller is awakened.
Optionally, in some embodiments, when the vehicle-mounted controller is in the pre-wake mode, recovery processing is performed on first execution data of the vehicle-mounted controller, where the first execution data includes any one or more of status data, message data, and read data of a status flag bit of the vehicle.
Specifically, the pre-wake mode is a transition mode from the pre-sleep mode to the normal working mode, when the second wake-up instruction is received, the vehicle-mounted controller restarts CAN transmission and resumes the first execution data of the vehicle-mounted controller, and when the first execution data of the vehicle-mounted controller is resumed, the pre-wake-up mode is ended and the vehicle-mounted controller is awakened.
Optionally, the method of the embodiment of the present application further includes: detecting whether the second execution data of the vehicle-mounted controller is stored completely or not when the vehicle-mounted controller is not detected to receive a second wake-up instruction; and if the second execution data is stored, ending the pre-dormancy mode, and controlling the vehicle-mounted controller to enter the dormancy mode.
The vehicle-mounted controller stores second execution data before entering a sleep mode, and the sleep mode indicates that the vehicle-mounted controller enters a low-power consumption state.
It should be understood that if the vehicle-mounted controller does not detect that the vehicle-mounted controller receives the second wake-up instruction, the vehicle-mounted controller can be controlled to enter the sleep mode, and in order to ensure that the vehicle-mounted controller can be quickly restored to the normal working mode after exiting the sleep mode, the embodiment of the application can control the vehicle-mounted controller to store second execution data when the vehicle-mounted controller does not detect that the vehicle-mounted controller receives the second wake-up instruction, close all the drives after the storage is completed, request the sleep wake-up chip and the power chip to execute sleep, and finally control the vehicle-mounted controller to enter the sleep mode.
Optionally, after controlling the in-vehicle controller to enter the sleep mode, the method further includes: detecting whether a third wake-up instruction sent by the second wake-up device is received or not, or timing the sleep duration of the vehicle-mounted controller; if a third awakening instruction is received or the sleep duration reaches a third preset duration, ending the sleep mode and awakening the vehicle-mounted controller.
The second wake-up device not only comprises a device connected with the vehicle-mounted controller through the CAN, but also comprises an external hardware device which is not connected with the vehicle-mounted controller through the CAN, the third wake-up instruction comprises a device connected with the vehicle-mounted controller through the CAN and a wake-up instruction sent by the external hardware device which is not connected with the vehicle-mounted controller through the CAN, and the third preset duration CAN be a duration preset by a user, CAN be a duration acquired through limited experiments, CAN also be a duration acquired through limited computer simulation, and is not particularly limited.
Specifically, after the vehicle-mounted controller enters the sleep mode, the vehicle-mounted controller CAN repeatedly detect whether all wake-up devices including the CAN send out a third wake-up instruction, detect whether the sleep duration reaches a third preset duration, and if any wake-up device is detected to send out the wake-up instruction, or the sleep duration reaches the third preset duration, end the sleep mode and wake-up the vehicle-mounted controller.
Optionally, the method of the embodiment of the present application further includes: when the duration of non-working of the vehicle-mounted controller reaches a first preset duration, if a first awakening instruction sent by the first awakening equipment is received, the vehicle-mounted controller is controlled to enter a normal working mode.
It should be understood that when the duration of non-working of the vehicle-mounted controller reaches the first preset duration, if the vehicle-mounted controller detects the first wake-up instruction sent by the first wake-up device, the vehicle-mounted controller can be directly controlled to enter the normal working mode because the vehicle-mounted controller does not perform the power-down dormancy processing on any data yet.
Optionally, the method of the embodiment of the present application further includes: after waking up the vehicle-mounted controller, controlling the vehicle-mounted controller to enter an initialization mode; and after the initialization is finished, controlling the vehicle-mounted controller to enter a normal working mode.
That is, after waking up the vehicle-mounted controller, the embodiment of the present application may control the vehicle-mounted controller to enter an initialization mode and perform an initialization operation, for example, by powering up the vehicle-mounted controller to implement initialization and the like, and after the initialization is completed, control the vehicle-mounted controller to enter a normal operation mode, so as to perform corresponding control according to a control request of the vehicle.
In order to enable those skilled in the art to further understand the sleep method of the vehicle-mounted controller according to the embodiments of the present application, the following detailed description is provided with reference to specific embodiments.
In this embodiment, as shown in fig. 2, fig. 2 is a schematic diagram of hardware connection involved in a sleep method of an in-vehicle controller according to an embodiment of the present application. In this embodiment, the TJA1145 sleep wake-up chip is described by taking a power chip with a sleep wake-up function as an example, and other chips with sleep wake-up functions can also realize the same function, which is not limited herein.
Specifically, when in the normal working mode, the TJA1145 chip and the main chip maintain the wake-up pin of the power chip through the pin, so that the power chip cannot enter the sleep mode. When in the sleep mode, the main chip and the TJA1145 chip are awakened and are not kept, the power supply chip enters sleep, and the power supply of the main chip and other peripheral driving chips is disconnected. The TJA1145 chip CAN receive a message sent by the vehicle-mounted controller, the TJA1145 chip and the main chip CAN be connected through a CAN, and communication CAN be realized between the main chip and the TJA1145 chip and before the main chip and the power chip based on SPI protocol (Serial Peripheral Interface ).
The operating mode design of the on-board controller may be as shown in fig. 3. And after the vehicle-mounted controller is electrified and initialized, the vehicle-mounted controller enters a normal working mode. And if the dormancy request is received and no other first awakening instruction is received at the moment, entering a pre-dormancy mode. In the pre-sleep mode, the in-vehicle controller performs data processing before sleep (i.e., second execution data) and turns off all the drivers. Meanwhile, the vehicle-mounted controller also periodically detects a second wake-up instruction, when the second wake-up instruction exists, the vehicle-mounted controller enters a pre-wake-up mode, in the pre-wake-up mode, the vehicle-mounted controller needs to restart CAN (controller area network) transmission, resumes the first execution data, then enters an initialization mode again, and finally enters a normal working mode after initialization is completed; and if the second wake-up instruction does not exist, then executing dormancy to enable the vehicle-mounted controller to enter a dormancy mode. In the process, the vehicle-mounted controller repeatedly detects a third wake-up instruction (wake-up instructions sent by all wake-up devices including the CAN), when the third wake-up instruction exists, the vehicle-mounted controller initializes, and enters a normal working mode after the initialization is completed.
Therefore, the problem that the vehicle-mounted controller cannot exit the sleep mode and data is abnormal when returning to the normal working mode from the sleep mode when the wake-up device sends a wake-up instruction in the sleep process is avoided.
Specifically, as shown in fig. 4, the sleep method of the vehicle-mounted controller includes the following steps:
s401, the vehicle-mounted controller enters a dormancy process.
S402, acquiring a first wake-up instruction.
S403, judging whether a first wake-up instruction exists, if yes, executing step S404, otherwise, executing step S405.
S404, the normal working mode is restored, and the step S416 is performed in a jumping manner.
S405, judging whether the CAN transmission is closed, if yes, executing step S408, otherwise, executing step S406.
S406, closing CAN message transmission.
S407, acquiring a second wake-up instruction, and jumping to execute step S405.
S408, judging whether the power-down storage is completed, if yes, executing step S409, otherwise, executing step S412.
S409, judging whether dormancy is completed, if yes, executing step S416, otherwise, executing step S410.
The sleep is completed, namely, entering a sleep mode.
S410, judging whether a second wake-up instruction exists, if yes, executing step S415, otherwise, executing step S411.
S411, executing the dormancy step, and jumping to the execution step S407.
S412, judging whether a second wake-up instruction exists, if yes, executing step S413, otherwise, executing step S414.
S413, the CAN transmission is resumed, and the step S415 is performed in a skip mode.
S414, storing the second execution data, and jumping to execute step S407.
S415, entering a pre-wake mode.
It should be noted that, in the pre-wake mode, the vehicle-mounted controller resumes the first execution data, then enters the initialization mode, and enters the normal operation mode after the initialization is completed.
S416, the dormancy process ends.
Therefore, through different operations of the three stages, on one hand, the recovery of each stage to a normal working mode can be ensured; on the other hand, excessive operations can be avoided from being executed, and the operation efficiency is prevented from being influenced.
According to the dormancy method of the vehicle-mounted controller, when the non-working duration of the vehicle-mounted controller reaches the first preset duration, whether the first wakeup command sent by the first wakeup device is received or not can be detected, if the first wakeup command is not received, the vehicle-mounted controller is controlled to enter a pre-dormancy mode, when the vehicle-mounted controller is in the pre-dormancy mode, whether the second wakeup command of the first wakeup device is received or not is detected every second preset duration, when the second wakeup command is detected to be received by the vehicle-mounted controller, the vehicle-mounted controller is controlled to switch from the pre-dormancy mode to the pre-wakeup mode, and after the first execution data of the vehicle-mounted controller are restored, the pre-wakeup mode is ended, and the vehicle-mounted controller is awakened. Therefore, the problem that the vehicle-mounted controller cannot exit from the sleep mode and is easy to generate data abnormality when the vehicle-mounted controller returns to the normal working mode from the sleep mode when the wake-up device sends a wake-up instruction in the sleep process in the related technology is solved, the vehicle-mounted controller can be returned to the normal working mode in the sleep execution process, the situation that the normal working mode cannot be restored when the wake-up source sends the wake-up instruction in the sleep process of the vehicle-mounted controller is avoided, and the execution efficiency is increased.
