- a mechanically or hydraulically actuated clutch the transmission behavior from the driver's foot to the torque build-up in the drive train is fixed unchangeable.
- an electronically controlled clutch system in which a clutch pedal sensor detects a driver-side actuation of a clutch pedal and in which an evaluation based on the detected clutch pedal operation determines a correlating clutch torque and with a corresponding clutch signal a clutch actuator activates the clutch.
- Such a generic electronically controlled clutch system is known from DE 10 2013 218 786 A1.
- the evaluation unit for controlling the clutch actuator on a sail detection unit by means of the current Driving parameters a sail driving condition is recognizable, which is suitable for a vehicle-side sailing operation.
- the presence of such a sailing driving condition is signaled to the driver. If an enable signal or an acceptance signal of the driver is present, the evaluation unit can automatically execute the sailing operation.
- the evaluation unit of the electronically controlled clutch system automatically opens the clutch in order to release a torque-transmitting connection between the drive unit and the transmission or the vehicle wheels.
- the object of the invention is to provide a driver assistance device for a motor vehicle, in which the driver can vary the vehicle behavior while driving in a simple manner.
- the coupling behavior or transmission behavior of the clutch can be adjusted on the driver side.
- the evaluation unit of the electronically controlled clutch system is assigned a driver-side operable input unit.
- the signal processing that is to say the determination of the clutch torque on the basis of the detected clutch actuation
- the signal processing in the evaluation no longer takes place in the first control mode, but in a different second control mode, thereby setting a different clutch behavior of the clutch.
- the clutch torque determination may preferably be based on a first characteristic (or an algorithm) stored in the evaluation unit. take place, by means of which from the detected clutch pedal operation, the thus correlating clutch torque is determined.
- the clutch torque determination can take place on the basis of a second characteristic curve (or algorithm) stored in the evaluation unit.
- the clutch actuation is detected by the clutch pedal sensor of the electronically controlled clutch system. If necessary, an absolute pedal position, a pedal travel and / or a pedal gradient can be detected by means of the clutch pedal sensor, which are used in the evaluation unit in the clutch torque determination.
- the first control mode in the evaluation unit of the electronically controlled clutch system can be factory-set.
- the first control mode can be designed so that there is a comfortable for the driver clutch behavior, which provides good accessibility of the clutch without jerking.
- the driver can select the second control mode exemplifying a transmission behavior corresponding to a mechanically or hydraulically operating clutch in which the torque buildup in the drive train is proportional to the clutch pedal position at startup.
- the clutch behavior is designed so that in comparison to the first control mode accelerated torque build-up in the drive train with a correspondingly greater responsiveness and with a jerking is possible.
- the input unit for driver-side selection of the first or second control mode can in a display system in the vehicle interior, for Example, an MMI (that is, man-machine interface), be arranged.
- MMI man-machine interface
- a third control mode can additionally be provided, which can be selected by the driver by means of the input unit.
- the third control mode is preferably designed such that additional functions of the driver assistance device can be selectively activated or deactivated in the third control mode switched by the driver. Such additional functions are activated in a factory setting.
- the driver when the third control mode is switched, the driver can selectively select or deselect individual additional functions in a selection menu.
- the evaluation unit of the driver assistance device reacts in the subsequent coupling process to the menu settings configured by the driver.
- the evaluation unit can have a sail recognition unit as an additional function.
- a sailing driving condition can be recognized, which is suitable for vehicle-side sailing operation.
- the evaluation unit In the presence of such a sailing driving condition, the evaluation unit generates a corresponding sail signal for the driver.
- the evaluation unit can automatically execute the sailing operation, that is, open the clutch automatically.
- the evaluation unit can, as a further additional function, have an overheating protection with which the current coupling temperature can be determined. If the current clutch temperature exceeds a threshold value, the evaluation unit controls the clutch (clutch actuator) automatically in order to open it.
- the overheat protection can be deactivated by the driver in the third control mode. In this case can if necessary in an emergency situation despite overheated clutch this still be operated.
- a start-up monitoring function can be integrated in the evaluation unit in order to protect the vehicle against unintentional engine stalling.
- an operating state can be identified on the basis of the current engine speed and a current accelerator pedal actuation, which leads to an engine stalling.
- the evaluation unit can open the clutch automatically, for example, to avoid engine stall during the starting process.
- Fig. 1 In a rough schematic block diagram of the powertrain of a motor vehicle with associated
- FIG. 1 a motor vehicle is sketched, whose internal combustion engine 1 can be coupled via a separating clutch 3 to a drive train 5.
- a manual transmission 7 is arranged, which is manually actuated by means of a manual switch 9.
- the transmission 7 is the output side connected to a front axle differential 1 1, with which the drive torque is transmitted to the front wheels 12.
- the front axle differential 1 1 is also connected via a propeller shaft with a rear differential 13, via which the drive torque to the vehicle rear wheels 14 is transferable.
- the internal combustion engine 1 and the clutch 3 are the driver via an accelerator pedal 1 5 and a clutch pedal 1 7 controlled.
- the separating clutch 3 is part of an electronically controlled clutch system, in which by means of a clutch pedal sensor 1 9 a driver-side operation s of the clutch pedal 1 7 is detected.
- the clutch system also has an evaluation unit 21, which determines a clutch torque M on the basis of the detected clutch pedal actuation s (ie, pedal travel, pedal position, pedal gradient) and drives a clutch actuator 23 of the clutch 3 with a corresponding clutch signal SKI , SKII.
- a first characteristic 27 and a second characteristic 29 are stored in the evaluation unit 21.
- an accelerator pedal sensor 24 is associated with a driver-side actuation of the accelerator pedal 15 can be detected.
- the evaluation unit 21 determines on the basis of the detected accelerator pedal actuation torque specification with which an engine control unit 25 of the internal combustion engine 1 can be controlled to generate an engine torque.
- the evaluation unit 21 is also in signal communication with an input unit 31, by means of which the driver can vary the coupling behavior of the separating clutch 3.
- the driver can select between the first characteristic curve 27 and the second characteristic curve 29.
- the evaluation unit 21 operates in a first control mode I, which is preset by way of example at the factory.
- the clutch behavior is designed comfortably, that is, a good Anfahriana is provided without juddering, in which during the starting a delayed (or gentle) torque build-up in the drive train 5.
- the driver selects the control mode II with its associated second characteristic curve 29, on the other hand results in a clutch behavior in which the separating clutch 3 reacts with high sensitivity and with judder, resulting in an accelerated torque build-up in the drive train 5.
- the driver can also switch over to a third control mode III by means of the input unit 31.
- additional functions 33, 35, 37 described below can be selectively activated by the driver or be deactivated.
- the additional functions 33, 35, 37 are provided in the driver assistance system in order to assist the driver while driving.
- the evaluation unit 21 may have as an additional function a sail detection 33, by means of the current driving parameters a sail driving condition can be determined, which is suitable for a vehicle-side sailing operation. In the presence of such a sailing driving state, the evaluation unit 21 generates a corresponding recommendation for the driver. In the case of a following driver-side release, the evaluation unit 21 can automatically activate the sailing operation, that is to say open the separating clutch 3 automatically.
- an overheat protection function 35 can be integrated in the evaluation unit 21 as a further additional function, in which the current clutch temperature in the separating clutch 3 can be determined. If the current clutch temperature exceeds a threshold value, the evaluation unit 21 controls the separating clutch 3 automatically in order to open it.
- a Anfahrwumbleter function 35 with which the vehicle is protected against unintentional engine stalling.
- an operating condition can be seen, which leads to an engine stalling.
- the evaluation unit 21 automatically opens the separating clutch 3 in order to avoid engine stalling.
