Description
Technical Field
The disclosure relates to the technical field of vehicles, and in particular relates to a vehicle control method, a device, electronic equipment and a storage medium.
Background
In a vehicle including an automatic transmission, when a driver releases an accelerator pedal while traveling, the vehicle is no longer accelerated, and the vehicle enters a coasting state. When the vehicle is in a coasting state, mechanical connection among the components of the power system is still maintained under the condition that the vehicle does not receive an acceleration command, that is, the engine, the transmission and the transmission shaft are not completely separated from each other until wheels are completely separated through a mechanism such as a clutch or a torque converter, and the components continue to operate as an integral system.
During the sliding process, the engine is not controlled by the driving force of the accelerator pedal, so that the engine does not output power any more, but is converted into a passive state, and the forward motion of the vehicle starts to drive the engine to rotate. The engine may produce a reverse drag effect on the driveline, so-called "engine cranking", due to friction inside the engine, pumping losses (energy loss caused by compression and pumping of air as the piston reciprocates in the cylinder), and other mechanical resistances. This drag effect is the drag that the engine generates as the vehicle advances, and consumes a portion of the kinetic energy of the vehicle, thereby causing the vehicle to slow down. When the vehicle decelerates quickly, the braking and decelerating feeling of personnel in the vehicle is strong, and the driving quality of the vehicle is affected.

Detailed Description
In order that the above objects, features and advantages of the present disclosure may be more clearly understood, a further description of aspects of the present disclosure will be provided below. It should be noted that, without conflict, the embodiments of the present disclosure and features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced otherwise than as described herein; it will be apparent that the embodiments in the specification are only some, but not all, embodiments of the disclosure.
Fig. 1 is a flowchart of a vehicle control method provided in an embodiment of the present disclosure. The method may be performed by a VCU (Vehicle Control Unit ) in a vehicle, the method comprising the steps of:
s110, acquiring vehicle running state data.
The vehicle operating state data may include, for example, at least one of: the current gear of the vehicle, the opening degree of an accelerator pedal, the opening degree of a brake pedal, the current vehicle speed, the working state of an automatic transmission and the current engine output torque.
S120, if the running state data of the vehicle meets the preset triggering condition, determining that the current vehicle is in a sliding state and the torque up processing is needed; the preset triggering conditions comprise: the current gear of the vehicle is a forward gear or a reverse gear, the opening of an accelerator pedal is zero, the opening of a brake pedal is zero, the current vehicle speed is greater than a preset vehicle speed, the working state of the automatic transmission is a sliding friction state or a locking state, and the current engine output torque is smaller than a set torque threshold.
The essence of this step is to determine whether the current vehicle is in a coasting state or not and whether the torque up process is required.
Whether the current vehicle is in a sliding state is judged, because in the existing vehicle, when the vehicle is in a sliding state and the speed of the vehicle is reduced quickly, the braking and speed reduction feeling of personnel in the vehicle is stronger. The present application is directed to solving this problem, and therefore, it is necessary to determine whether the current vehicle is in a coasting state.
The torque up process may be, for example, boosting or increasing engine output torque.
Whether the torque up processing is needed is judged because in practice, whether the torque up processing is carried out on the engine is expected to be determined according to the actual running condition of the vehicle, rather than neglecting the actual running condition of the vehicle, the torque up processing is carried out on the engine blindly. The arrangement can reduce potential safety hazards caused by blindly carrying out torque up treatment on the engine.
The current gear of the vehicle is a forward gear or a reverse gear, the opening of an accelerator pedal is zero, and the opening of a brake pedal is zero, which means that the vehicle is currently in a sliding state.
The reason why the preset trigger condition is set includes that the current vehicle speed is greater than the preset vehicle speed is to prevent the risk of runaway caused by an unexpected increase in torque when the vehicle is running at a low speed. In particular, if the engine torque is suddenly raised at a low vehicle speed, the vehicle may undergo a strong acceleration reaction that is inconsistent with the expectations of the driver, and such unexpected power increase may not only cause discomfort in the driving experience, but may also cause a safety accident in extreme cases. By setting a vehicle speed threshold (namely, a preset vehicle speed), the torque up operation is ensured to be executed only when the vehicle reaches a sufficient speed, so that the driving operation is ensured to be consistent with the expected operation, and the driving safety is improved.
In the "current engine output torque is smaller than the set torque threshold", the set torque threshold is a pre-specified torque threshold that is used to measure whether or not the torque up process is required. In some scenarios, the set torque threshold is related to the current gear of the vehicle, i.e., if the current gear of the vehicle is different, the set torque threshold as used herein is different. The reason for this is that the speed ratios of the gearboxes differ when the vehicle is in different gear positions. This means that if the engine outputs the same torque, the torque ultimately transmitted to the wheels via the transmission is different when the vehicle is in different gears, which in turn results in a different braking deceleration feel for the person in the vehicle. In the case where the braking deceleration feeling is weak, it is unnecessary to additionally perform the torque up process on the engine.
In practice, the operating states of an automatic transmission include a slip state, a locked state, and an unlocked state, and the slip state may refer to, for example, a state in which power transmission is not completely coupled within the automatic transmission during a gear shift or under a specific control strategy. The lockup state may be, for example, a state in which a lockup clutch (Lock-up Clutch) in a torque converter in an automatic transmission is operated. When the transmission reaches a certain running condition (such as high-speed stable running), a locking clutch in the hydraulic torque converter is engaged to directly mechanically lock the engine and an input shaft of the transmission so as to realize 'rigid connection' in order to improve transmission efficiency and fuel economy. At this time, the power transmission becomes direct transmission, almost no slip loss, and the transmission efficiency can be improved. The open state may be, for example, the transmission being disconnected from the engine. When the operating state of the automatic transmission is a slip state or a lockup state, which means that the transmission system is connected, the torque output from the engine can be output to the wheels through the transmission system. When the operating state of the automatic transmission is an on state, which means that the transmission system is disconnected, the torque output from the engine cannot be output to the wheels through the transmission system.
Setting the preset trigger condition includes the operating state of the automatic transmission being a sliding state or a locked state. The reason for this is that when the operating state of the automatic transmission is an on state, the torque output from the engine cannot be output to the wheels through the transmission system, so that no reverse drag effect occurs, and no strong feeling of braking and decelerating by a person in the vehicle is caused, and no torque up of the engine is required.
S130, if the current vehicle is in a sliding state and the torque up processing is needed, the torque up processing is carried out on the engine so as to reduce the sliding resistance of the vehicle.
There are various ways to implement this step, and the present application is not limited thereto. Illustratively, the method for implementing the step includes: performing torque up processing on the engine according to a first preset adjustment slope until the output torque of the engine is equal to the target torque; the target torque is related to the current gear of the vehicle; or carrying out the torque up treatment on the engine according to the first preset adjustment slope until the duration of the torque up treatment on the engine reaches the preset duration.
The target torque may be, for example, a pre-calibrated torque associated with the current gear of the vehicle. Alternatively, the vehicle is currently in a different gear and the target torque is different.
Further, before the engine is subjected to the torque up process with the first preset adjustment slope until the output torque of the engine is equal to the target torque, the method further includes: based on the current gear, a target torque is determined. The function of setting the target torque is to reasonably control the speed of the vehicle in the sliding state of the vehicle, so that potential safety hazards caused by torque increase are avoided.
The first preset adjustment slope is a pre-designated parameter, limits the increment of torque in unit duration, and is set for reasonably controlling the speed of the vehicle in a vehicle sliding state, so that potential safety hazards caused by too fast torque lifting are avoided.
The purpose of setting the torque up processing is carried out on the engine until the duration of the torque up processing is up to the preset duration by the first preset adjustment slope is to limit the duration of the torque up of the engine in time.
In some scenes, the engine is subjected to the torque up treatment according to the first preset adjustment slope until the duration of the torque up treatment on the engine reaches the preset duration, and the torque up treatment is performed on the engine according to the first preset adjustment slope until the output torque of the engine is equal to the target torque, so that the situation that the engine is always in the process of increasing the torque due to the program defect is avoided.
Optionally, after S130, the method further includes: and keeping the output torque of the engine unchanged until the running state data of the vehicle does not meet the preset triggering condition.
Illustratively, if the preset triggering condition includes: the current gear of the vehicle is a forward gear or a reverse gear, the opening of an accelerator pedal is zero, the opening of a brake pedal is zero, the current vehicle speed is greater than a preset vehicle speed, the working state of the automatic transmission is a sliding friction state or a locking state, and the current engine output torque is smaller than a set torque threshold. The preset triggering conditions comprise a plurality of sub-conditions, wherein the current gear of the vehicle is a forward gear or a reverse gear, the opening degree of an accelerator pedal is zero, the opening degree of a brake pedal is zero, the current vehicle speed is greater than the preset vehicle speed, the working state of the automatic transmission is a sliding state or a locking state, and the current engine output torque is smaller than a set torque threshold value and is the sub-preset triggering conditions. If at a certain moment, the vehicle running state data does not meet one or more sub-preset trigger conditions in the preset trigger conditions, and the moment is determined that the vehicle running state data does not meet the preset trigger conditions.
The method comprises the steps of setting and keeping the output torque of an engine unchanged until the running state data of the vehicle does not meet the preset trigger condition, wherein the essence is that after the running state data of the vehicle is detected to meet the preset trigger condition, the engine is subjected to torque up processing, and then the output torque of the engine is kept to be the torque after the torque up processing is finished all the time until the running state data of the vehicle does not meet the preset trigger condition.
Optionally, the method may further include, after the vehicle running state data does not satisfy the preset trigger condition, keeping the engine output torque unchanged: and adjusting the output torque of the engine with a second preset adjustment slope so as to gradually reduce the output torque of the engine.
The second preset adjustment slope is similar to the first preset adjustment slope, is a pre-designated parameter, limits the reduction amount of torque in unit duration, and is set for reasonably controlling the speed of the vehicle, so that potential safety hazards caused by too fast torque reduction are avoided.
Illustratively, when it is detected that the opening of the brake pedal is greater than 0, or the opening of the accelerator pedal is greater than 0, or the state of the automatic transmission is an open state, the output torque of the engine is gradually reduced.
According to the technical scheme, if the running state data of the vehicle meets the preset triggering conditions, the current vehicle is determined to be in a sliding state, and the torque up processing is required; the preset triggering conditions comprise: the method comprises the steps that a current gear of a vehicle is a forward gear or a reverse gear, the opening of an accelerator pedal is zero, the opening of a brake pedal is zero, the current vehicle speed is greater than a preset vehicle speed, the working state of an automatic transmission is a sliding friction state or a locking state, and the current engine output torque is smaller than a set torque threshold; if the current vehicle is in a sliding state and the torque up processing is needed, the torque up processing is carried out on the engine so as to reduce the sliding resistance of the vehicle. The essence of the method is that when the vehicle is in a proper time under a sliding state, the output torque of the engine is improved, and the purposes of weakening the resistance caused by the drag effect, reducing the braking and decelerating degree of the vehicle and relieving the braking and decelerating feeling of personnel in the vehicle are achieved.
