Definitions
- the present invention relates to a method and a device for controlling an automatic or automated motor vehicle clutch according to the preamble of patent claim 1 or of patent claim 7.
- Automatic or automated motor vehicle clutches are friction clutches which are disengaged or engaged by means of a pneumatic or hydraulic actuator while the movement in the other direction of adjustment is accomplished by a clutch spring.
- the actuator is driven, for example, with the interposition of a clutch controller by a vehicle control, which receives as input a signal corresponding to a clutch pedal travel signal (automated clutch) or a predetermined by a clutch control program signal.
- a displacement sensor which detects the travel of a mechanically connected to the actuator component, provides a reference signal serving as a path signal to the vehicle control.
- the path signal represents the current degree of engagement of the clutch, which the vehicle controller evaluates for the control process.
- the clutch transmission torque can be determined by means of appropriate functions.
- redundancies are realized in such a way that a plurality of similar systems, in the present case, several displacement sensors are arranged parallel to each other, so that in case of failure of a displacement sensor whose function is taken over by the other displacement sensors.
- This redundancy philosophy then reaches its limits when, for example, a subordinate components, only once existing component fails, because then the redundancy of the multiple components no longer comes into play.
- the present invention seeks to provide a method and a device for controlling an automatic or automated, actuated by a pressure fluid actuator vehicle clutch with a degree of engagement detecting displacement sensor and with a function of this displacement sensor securement redundancy, in which the disadvantages of the so-called simple redundancy described above do not occur.
- the invention is based on a method and a device for controlling an automatic or automated, actuated by a Druckfluid Stellanthebes clutch of a motor vehicle, in which the path of a connected to the actuator component (actuator) detected by a displacement sensor and as a controlled variable in a is input with a vehicle controller cooperating clutch controller.
- the current pressure profile in the actuator is stored in the disengagement and engagement movement of the clutch and compared with the path of the actuator, and that said pressure-travel characteristic is updated with the current pressure values.
- This updating of the pressure-displacement curve is carried out either at each clutch actuation or at predetermined intervals.
- the inventive method thus offers the possibility that, for example, the current Ausgurkraftkennline learned automatically by the vehicle control and then used to optimize the cooperating with the vehicle control clutch controller.
- a hysteresis in the reversal of motion or stick-slip effects of the mechanical components of the clutch control cause that detected by the displacement sensor current travel position of the actuator deviates from the assigned via the characteristic of this positional position pressure in the actuator.
- this deviation can be automatically detected by the vehicle control, and the characteristic curve can then be autonomously modified in order to reduce these effects or completely cancel them out.
- a fluid pressure in the actuator measuring pressure sensor is provided, whose output is connected to the vehicle control, and stored in the vehicle control a fluid pressure associated with the path of the actuator characteristic is, so that the fluid pressure is used as the path of the actuator redundant control variable in the vehicle control.
- the method according to the invention or the device according to the invention have further advantages.
- the signals of the pressure sensor for checking the signals of the displacement sensor or vice versa for plausibility can be used, ie a discrepancy between these signals indicates a malfunction of the displacement sensor or the pressure sensor.
- a constant evaluation of the course of Ausgurkraftkennline the clutch is possible, for example, a check is made whether this Ausschreibkraftkennline holds within predetermined limits.
- a transmission 2 associated clutch 4 is actuated via a fluid pressure actuator 6.
- the actuator 6 comprises a cylinder housing 8 and a piston 10 arranged therein axially displaceable, which is operatively connected via a piston rod 12 with the clutch 4. It is assumed that the clutch 4 is an actively opening clutch, which is closed by a clutch spring, not shown, and opened by the actuator 6.
- the actuator 6 is shown in the present embodiment as a hydraulic actuator, which is controlled via a valve assembly 14.
- hydraulic fluid drawn in by a pump 16 from a tank 18 is supplied via the valve arrangement 14 and a pressure fluid line 20 to the head chamber 22 of the cylinder housing 8, so that the piston 10 shifts to the right in the figure and the piston 10 moves Clutch 4 opens against the force of a clutch spring.
- the pressure fluid line 20 is connected by means of the valve assembly 14 to a return line 24, so that the piston 10 is displaced to the left under the action of the clutch spring not shown in the figure and located in the head chamber 22 hydraulic fluid via the pressure fluid line 20, the valve assembly 14 and the return line 24 is pushed into the tank 18.
- the valve assembly 14 is driven by a vehicle controller 26 which includes a cooperating clutch governor.
- This vehicle controller 26 receives input signals (automated clutch) input from a driver via a clutch pedal or input signals (automatic clutch) generated depending on input characteristics such as engine torque, engaged gear, vehicle speed, and the like.
- the movement of the piston rod 12 is detected by means of a displacement sensor 28, then input to the vehicle controller 26 with the clutch controller and utilized in this.
- the hydraulic fluid pressure in the head chamber 22 is detected by a pressure sensor 30 and a signal derived therefrom is also input to the vehicle controller 26 where it is evaluated in the manner described above.
- a desired characteristic 32 is stored, which indicates the desired fluid pressure as a function of the travel position of the piston rod 12. As long as the actual fluid pressure matches the desired fluid pressure, the system will operate properly.
- a deviation of the actual fluid pressure from the target fluid pressure is an indication of an irregularity in the system, which in the manner described above, e.g. may indicate leaks in the system or the need to re-optimize the clutch governor.
- the pressure sensor 30 delivers a path information associated with the measured pressure via the characteristic curve 32, so that at least one emergency driving function is maintained.
