Definitions
- the invention relates to a method and a device for controlling a drive unit of a vehicle according to the preambles of the independent claims.
- Rate of change of the torque structure of the drive unit limited.
- the operating situation in the foreground is the transition from the overrun phase of the vehicle to the pull phase when the driver operates the accelerator pedal.
- the limitation is given as a compromise between the vibration-reducing effect on the one hand and the desire to make the torque desired by the driver available as quickly as possible.
- From DE-Al 28 04 444 (GB-A 20 13 937) it is known to limit the change in the duration of fuel injection pulses.
- DE-Al 41 07 115 (GB-A 22 53 440) it is known to change the torque during the transition from overrun mode to train mode of an internal combustion engine
- Torque change Depending on the application, they are used individually or in any combination or in a modified form. In the following, these functions and functions with a comparable effect but a different design are used as limitations of the
- the driving behavior of a vehicle is optimized with regard to the torque change of the drive unit by the solution according to the invention.
- Operating condition limited is influenced according to the driver's behavior.
- Transmission control sports, economy, etc.
- the driver type determined by this is derived.
- the engine control system controls the torque build-up according to the driver type specified by the driver.
- the torque build-up of an internal combustion engine is advantageously controlled in accordance with the driver's behavior, so that the driving behavior of the vehicle is adapted to the driver.
- the driver actively has the possibility of determining the build-up of torque and thus the driving behavior of the vehicle.
- the solution according to the invention makes it possible, depending on the driver type, to implement both a rapid torque build-up and a comfortable, smooth torque build-up.
- winter button present in transmission controls is advantageously possible To design torque build-up so smoothly that the wheel's tendency to spin is prevented with a corresponding coefficient of friction.
- Another advantageous addition is that information supplied by a control unit for regulating the traction slip of a vehicle about a control intervention in the braking system of the vehicle is evaluated and transmitted to the engine control system that the torque change is slowed down by the engine control system. The annoying, fast torque change during traction control intervention is avoided.
- FIG. 1 shows an overview circuit diagram of an example of control of a drive unit
- FIG. 2 shows a preferred embodiment of the solution according to the invention on the basis of a flow chart
- Figure 3 finally shows timing diagrams of this preferred embodiment.
- FIG. 1 shows an electronic control unit 10 which has an input circuit 12, at least one microcomputer 14 and an output circuit 16.
- Input circuit, output circuit and microcomputer are one Communication system 18 linked to each other for mutual data and information exchange.
- the input circuit 12 of the control unit 10 is supplied with the input lines 20, 22 and 24 to 26, which are optionally combined in a bus system (for example CAN), and which are connected by at least one further control unit 28 for controlling an automatic transmission and / or a control unit for regulating the drive slip, from a measuring device 32 for detecting the degree of actuation of an operating element 20 and from measuring devices 34 to 36 for detecting other operating variables of the drive unit and / or the vehicle such as engine speed, engine temperature, engine load, etc. are supplied.
- a bus system for example CAN
- the control unit of the engine, the transmission and / or a traction control system can also be implemented together as a so-called “power train” control unit.
- the control unit 10 influences the torque of the drive unit (not shown) via the output circuit 16.
- the control unit 10 may influence the Air supply to the internal combustion engine (symbolized by the output line 40), the fuel metering (symbolized by the output line 42) and / or the ignition angle (symbolized by the output line 44).
- the microcomputer 14 determines a target value for a torque from the degree of actuation of the control element and further operating variables, such as, for example, the engine speed
- this target value is converted into control signals for influencing parameters controlling the torque in the sense of an approximation of the actual torque to the target torque.
- the target torque the so-called driver request
- the target torque is filtered with a view to reducing or reducing vibrations in the drive train of the vehicle, i.e. subjected to an increase limitation. Accordingly, the torque build-up is limited when the operating element is actuated, for example from the released position.
- the microcomputer 14 can also include other programs that lead to a limitation of the torque change, such as limits on the rate of change of the throttle valve adjustment, the fuel injection pulses and / or programs that influence the torque of the drive unit in a vibration-reducing manner when a torque fluctuation is detected.
- Torque change in particular the torque build-up, to be controlled depending on variables which are supplied to the engine control system by other control systems which do not directly control the drive unit, for example a transmission control and / or a control unit for traction control.
- a transmission control the driver's behavior
- the driver's behavior for example, is "Economy", "Sport” or "Winter”. This information is transmitted via an interface to the engine control.
- the engine control now selects the procedure that corresponds to the driver's behavior a rapid build-up of moments is desired, which gives the driver a spontaneous
- a factor is derived from operating variables that represents the respective driver type.
- Another important piece of information, in the dependence of which the engine control influences the change in torque, is, in an advantageous exemplary embodiment, the information about control interventions of a traction control system on the brake of the vehicle, which is supplied to the engine control by a corresponding control unit.
- the solution according to the invention is shown in a preferred exemplary embodiment with reference to the flow chart of FIG. 2.
- the program part described in FIG. 2 is initiated at predetermined time intervals, for example a few milliseconds. It describes the control of the limitation of the rate of change of the driver's request derived from the control element actuation. Accordingly, this control must be applied to all other limitations implemented in the motor control.
- a driver request FW preferably a target torque
- information from other control systems for example a driver type signal FT or information about the gearbox setting made by the driver, whether economy, sport or winter setting, determined in accordance with predetermined characteristic maps , tables or calculations in another program part was selected, or in an advantageous embodiment, information about the status of a traction control system.
- a change in torque is predefined by the driver, that is, in the preferred exemplary embodiment, whether the driver's request has changed accordingly. It is provided in the preferred embodiment that only a torque increase is queried in step 104 and the limitation is only influenced in this case. In the event of a torque reduction, a predefined change limitation, which is as small as possible, is then active for all operating states.
- step 106 possibly queried whether the winter setting of the transmission is selected. If this is the case, step 108 checks, if necessary, whether brake intervention of the traction control system is active. If this is the case, at least one change limit, e.g. the
- Change limitation of the driver's request is set to a first value Kl, in the opposite case to a second value K2 (cf. steps 110 and 112).
- Kl e.g. Low-pass filter with variable constants used, whereby Kl, K2, etc. represent these constants.
- step 114 a check is carried out in step 114 as to whether a brake intervention by the Traction control is active or detects the traction control at the risk of a low ⁇ value. If this is the case, the at least one change limitation is set to a value K3 (step 116), in the opposite case to a value K4 which is dependent on the driver type (step 118).
- the value K4 is read from a characteristic curve or a table in which it is stored depending on the driver type or the gearbox setting.
- step 110 After step 110, 112, 116 or 118 the
- the specification of the limit values is carried out in the increasing direction with each change in torque.
- the filtering of the change in torque is only carried out in certain operating situations, for example when changing from or into the idle position of the control element or when changing from a pushing operation to a pulling operation of the drive unit and when torque fluctuations are detected.
- At least one manipulated variable for example the control signal for an electrically actuated throttle valve
- the constants of controllers for example the torque or position controller, or the constants of an anti-jerk controller, depending on the supplied additional information can be changed such that a rapid torque build-up takes place when the vehicle's sporty behavior is predetermined by the driver, and a gentle torque build-up takes place given a comfortable, economical driving style.
- FIG. 3 An example of the mode of operation of the solution according to the invention is shown in FIG. 3.
- Figure 3a shows the time course of the degree of actuation of the control element
- Figure 3b shows the time course of the motor torque.
- the driver actuates the control element from the rest position of the control element (FIG. 3a).
- torque is built up from the time TO.
- the speed of the torque build-up is determined by suitable measures (filtering the degree of actuation, the derived one
- Driver request a control signal for adjusting a performance parameter of the drive unit, by appropriate selection of the constants of an adjusting controller). If there is information about a sporty behavior of the driver, the moment builds up quickly
