Definitions
- the invention relates to the automatic control of a clutch arranged in the drive train of a motor vehicle between an internal combustion engine provided as a vehicle engine and driven vehicle wheels, the vehicle having a sensor system for detecting speeds of the vehicle engine and the controller opening the clutch below a threshold value of the engine speed, which opens is increased if the engine speed drops too fast.
- motor vehicles with arbitrarily shifted transmissions and automatically controlled clutch have been known for a long time.
- DE 43 16 421 AI relates to automatic control of a clutch in a vehicle with traction control.
- the control circuit of the traction control system controls an actuator acting on a power actuator of the internal combustion engine of the vehicle when an existing or starting traction slip situation is detected.
- the control circuit generates a control signal during the traction slip situation, which causes the clutch control to hold the actuator of the clutch in the clutch position existing at the start of the traction slip situation and / or to reduce the actuating rate of this actuator.
- DE 36 30 750 AI relates to a device used for clutch actuation in a motor vehicle, in which the functional connection between an actuator of the clutch and a clutch pedal actuated by the driver takes place via an interposed electronic control unit.
- a first displacement sensor is located on the clutch pedal to determine a setpoint.
- a second displacement sensor for determining an actual value is arranged on the actuating element of the clutch.
- the actuating member of the clutch is connected to an actuating cylinder which can be adjusted by means of a control valve depending on the output signals of the electronic control unit.
- the electronic control unit receives an additional signal from a control unit which is generated when a control function of an anti-lock control system of the vehicle brake occurs. In this way, the clutch can be actuated without the driver's intervention when the brake is anti-lock.
- the object of the invention is now to optimize the clutch control of the type specified.
- the sensor system also detects the speeds of the vehicle wheels and the control system opens the clutch even when the speed differences of the vehicle wheels are excessive and / or when the drive wheels start to spin below the increased threshold value of the engine speed.
- the invention makes it possible to brake the vehicle to a standstill with the maximum possible deceleration without running the risk of stalling the engine.
- the engine cannot be brought to an unintentional stop even if the driven vehicle wheels initially spin on a slippery road surface and then suddenly regain good traction on a part of the road surface with a high coefficient of friction, the previously high speed of the drive wheels practically abruptly reaching an almost vanishing value can sink.
- the strongly braking drive wheels cannot "pull" the motor to a standstill. The same applies if there are larger speed differences between the vehicle wheels. Even in such a case, a sudden reduction in the speed of the motor must be expected as soon as the drive wheels get good traction again.
- the invention is based on the general idea of always opening the automatically controlled clutch prematurely if, in the particular driving situation, extreme engine speed changes, in particular with a strong speed reduction, are likely to occur in the case of a closed clutch.
- the single figure shows a highly schematic, circuit-diagram-like top view of a motor vehicle according to the invention.
- a motor vehicle which is otherwise not shown in detail, has non-driven front wheels 1 and driven rear wheels 1.
- Terckenment 2 which are connected or connectable to an internal combustion engine 6 via a propeller shaft 3, a conventional manual transmission 4 operated arbitrarily by the driver and an automatically controlled clutch 5.
- the vehicle has an electronic control 7, which can take on a variety of functions, as shown below.
- the electronic control is connected on the input side to a comprehensive sensor system, which includes, among other things, the speed sensor 8 assigned to the vehicle wheels 1 and 2, a sensor arrangement 9 for monitoring the speed and power of the internal combustion engine 6, and a sensor arrangement 10 for detecting the driver's switching intentions or for detection the engaged gear of the manual transmission 4 and a transmitter device 11, which reports the operating state of the clutch 5.
- a comprehensive sensor system which includes, among other things, the speed sensor 8 assigned to the vehicle wheels 1 and 2, a sensor arrangement 9 for monitoring the speed and power of the internal combustion engine 6, and a sensor arrangement 10 for detecting the driver's switching intentions or for detection the engaged gear of the manual transmission 4 and a transmitter device 11, which reports the operating state of the clutch 5.
- the electronic control 7 can take over an anti-lock control on the basis of the signals from the speed sensors 8 on the vehicle wheels 1 and 2, i.e. when the wheel brakes 12 are actuated by the driver, the braking force is possibly reduced wheel by wheel if one of the wheels 1 or 2 should lock.
- the electronic control 7 can also act as an anti-slip control in that a rear wheel 2 or both rear wheels 2 are braked briefly if one rear wheel or both rear wheels 2 should spin when the vehicle is accelerating.
- the clutch 5 is generally actuated as a function of the signals from the sensor arrangement 9 and the transmitter arrangement 10, ie in particular the clutch 5 is automatically opened by the electronic control 7 when the driver switches the transmission 4.
- the clutch 4 When starting the vehicle, the clutch 4 is increasingly closed with increasing speed and power of the motor 6, the speed of the drive wheels 2 also being taken into account in the clutch control.
- the clutch 4 is automatically opened as soon as the speed of the engine 6 falls below a low threshold value.
- the aforementioned speed threshold should be as low as possible, for example in the vicinity of the idling speed of the engine 6. This is possible without risk of "stalling" of the motor 6 at least if the preceding speed reduction of the motor 6 takes place comparatively slowly.
- the threshold value of the engine speed below which the clutch 5 is automatically opened by the controller 7 is raised.
- the speed of the motor 6 can be stabilized by the controller 7 without great effort and the motor 6 can be prevented from stalling. ?
- the threshold value of the engine speed below which the clutch 5 is opened is also increased if the speed of the drive wheels 2 exceeds the speed of the non-driven wheels 1 by more than a tolerance value.
- the fact is taken into account that drive wheels 2 spinning on a slippery roadway can be braked almost suddenly when the drive wheels 2 again receive good traction. Without an increase in the minimum speed of the engine 6 below which the clutch opens, the engine 6 could then stall.
