Definitions
- the invention relates to a control device for actuators an internal combustion engine, a control unit for actuators an internal combustion engine and a method for controlling an internal combustion engine.
- Known control devices for actuators of internal combustion engines generate i.a. Control signals for controlling actuators and control commands for actuating actuators, wherein the control signals and commands for controlling Actuators dependent on at least one measured variable, such as an accelerator pedal value or the speed.
- the actuators can be driven by actuators.
- Actuators are partially provided control units that depending on the control commands of the control device actuating signals generate for the actuators of the internal combustion engine.
- Both the controller and the control unit each have a communication interface to which a Bus, such. B. the CAN bus can be connected.
- the control device can then use the control commands over the interface and send the bus to the control unit, which will then send the appropriate ones Performs control tasks.
- Such control commands can z. B., at which crankshaft angle Gas exchange valves should be opened or closed.
- the object of the invention is to provide a control device for Actuators of an internal combustion engine, a control unit for Actuators of the internal combustion engine and a method for To provide control of the internal combustion engine which ensure that the internal combustion engine in different modes is operable with constant control commands.
- the object is achieved by the features of the independent claims.
- the invention is characterized characterized in that the internal combustion engine in different modes, such as b. Two-bar, four-bar, six-bar, Eight-clock can be operated without the control commands have to be changed.
- the crankshaft angle sensor comprises a sensor 6, which is preferably formed as a Hall element and firmly arranged in the crankcase of the internal combustion engine is.
- the sensor 6 generates a pulse-shaped measuring signal MS, when the crankshaft 4 rotates.
- the measuring signal MS has at a constant speed a constant period of the pulses to a larger period due to the gap in the gear or a uniform pulse-pause ratio except for a longer break per revolution, conditional through the gap in the gear. This longer gap or too larger period duration serves as a synchronization signal SYNC.
- the control device 9 is connected via a signal line 8 with the Sensor 6 connected. Furthermore, it is via a bus 14, which is preferably designed as a CAN bus, with a control unit 12 connected. To connect the bus are respectively Communication interfaces in the control device 9 and the control unit 12 is provided.
- the communication interfaces However, for example, as a transmission and / or Receiving devices for the wireless transmission of information be educated.
- the control unit 12 detects and generates actuating signals for Actuation of electromechanical actuators 13 for gas exchange valves the internal combustion engine.
- the control unit 12 communicates via the bus 14 with the control device 9 Controller 9 generates control commands e.g. over the beginning of the opening and the opening end of the gas exchange valves.
- the control unit 12 is likewise via the signal line 8 connected to the sensor 6.
- FIG. 2 is a flow chart of a program for determining the count of a first counter Z1 shown which runs in the control device 9.
- a step S1 the program is started.
- step S2 it is checked whether the measurement signal MS a rising edge has. If this is not the case, then the condition of step S2 checked again, if necessary after one predetermined delay time. Is the condition of However, step S2 satisfies, the first counter Z1 is reversed increments the value one.
- a step S2a it is checked whether the measurement signal MS is a rising edge has. If this is not the case, then the condition of step 2a, possibly after a predetermined Waiting time, checked again. If this is the case, then in a step S3a, the second counter Z2 is incremented by the value 1.
- the remarks on the first counter Z1 apply mutatis mutandis for the second counter Z2.
- steps S2 in FIG. 2 and S2a in FIG. 3 can alternatively also be tested. whether the measuring signal MS has a falling edge. It is advantageous if the first and second counters Z1, Z2 the have the same bit length or at least the control device 9 and / or the control unit 12, the respective bit length of know first and second counter Z1, Z2.
- the control device 9 generates control commands for controlling the designed as gas exchange valves actuators dependent on at least one measured variable, such as the speed, the accelerator pedal value a pedal encoder or other measurands.
- commands can use the command to open a or more gas exchange valves associated with a cylinder or just to be close to it.
- the control commands each contain a target meter reading, the second counter Z2 should occupy in the control unit, if the control task associated with the control task performed shall be.
- the tax task may open or closing or the oscillation of a gas exchange valve be.
- the control unit 12 are electromechanical Actuators 13 assigned to control the gas exchange valves.
- FIG. 4 shows a program which is preferably present in the control unit 12 cyclically or as an interrupt procedure becomes.
- the program is started.
- a step S9 it is checked whether via the communication interface the control unit 12, a control command from the Control device 9 was received. This is not the case, so the program is stopped in a step S11. Is this However, the control command is in one step S12 processed. In an action table AT, the target count, which was transmitted with the control command, and the associated action, such as valve opening or Valve closing stored in the action table. In one Step S11 then the program is stopped. The program is then preferred either at the occurrence of the event "Receive control command" or after a specified waiting time called again.
- step S18 in which it checks whether the meter reading since the Implementation of step S16 has changed. Is not this If so, the program is stopped. Otherwise, the Processing continues in step S16.
- control commands used to control the actuators of Various cylinders are provided, all in the common action table AT are stored as the meter readings regardless of a reference to the respective upper Dead center at ignition or another cylinder-specific Reference point are. Therefore, just a two, realized four, six or eight-stroke operation of the internal combustion engine be without making adjustments to the control commands and the interfaces of the control device and the control unit necessary.
- the transmission of the control commands from the control device 9 to the control unit 12 can in principle at any time taking into account the processing required Calculation time. By means of the circulating first and the second counter, a reference is created which can be found both in the control device 9 as well as in the control unit 12 known is.
- control commands for use in various engine types eg. B. different numbers of cylinders do not need to be modified.
- Process-optimal Transmission time or transmission crankshaft angle for the Control commands can be defined by the control device 12 become. You do not have to set a maximum speed for that Calculation and positioning times are sufficient, be determined.
