Definitions
- the invention relates to a method for controlling a clutch according to the
- the preamble of claim 1 Furthermore, the invention relates to a coupling for a vehicle according to claim 10.
- a method for clutch control is known from DE 103 10 471 A1, for example. There is a sensor on a gearshift lever of a manual transmission
- the sensor is a position sensor, which the
- Shift lever position recognizes a shift request.
- a shift request is also arranged on the shift lever
- Shift travel sensor recognized.
- the clutch is fully opened while the selector lever overcomes a free travel.
- the clutch actuation for an automated clutch in a vehicle can be initiated when a shift request is recognized in order to automatically open the clutch so that the driver can change a shift position in the transmission using the gear selector lever. If a switching request is recognized, the
- Clutch actuation is automated, but independent of the driver's driving style. It can happen that the shifting process is perceived as too hard if the clutch actuation speed is set too low.
- the object of the present invention is to improve a method for controlling a clutch.
- a clutch should be able to be controlled better. Furthermore, it should be possible to adjust the clutch actuation to the driver's driving style.
- At least one of these objects is achieved by a method for controlling a clutch having the features according to claim 1. This allows the
- Clutch actuation adapted to the driving style of the driver.
- the driving behavior and comfort of the vehicle are improved.
- the clutch can be actuated via an ECM system.
- the clutch actuation device can be electrically controllable.
- the gear selection position can be detected via a position sensor.
- Position sensor can be assigned to the gear selection element.
- the current gear selection position is recorded and compared with a first stored gear selection position previously stored in a memory, the difference between the current and the first
- stored gear selection positions is formed as the first difference and the amount of the first difference is compared as the first gear selection position change with a predetermined change threshold value and if the first
- Gear selection position change is greater than or equal to the change threshold value, a detection start point for detecting the gear selection speed is set.
- the change threshold value can be fixedly predetermined during operation of the clutch or can be changed during operation of the clutch.
- the current gear selection position is stored in the memory if the first gear selection position change is less than the change threshold value.
- the current gear selection position is recorded and additionally stored with a time before the first one
- the gear selection position is compared, the difference between the current and the second stored gear selection position being formed as the second difference and the amount of the second difference being compared as the second gear selection position change with the specified change threshold value and, if both the first and the second gear selection position change is greater than or equal to the change threshold value, the detection start point is set to detect the gear selection speed and otherwise the current gear selection position is stored in the memory.
- n gear selection position changes can depend on a memory size made available in the memory.
- Memory size can be fixed or variable.
- the memory size of the memory can depend on an operating state of the vehicle and / or on driving conditions.
- Gear selection position deleted from memory This allows the memory space in the memory to be released for newer gear selection positions.
- the detection time difference can be fixed or variable.
- Gear selection speed can be formed as the quotient of the gear selection position difference and the detection time difference.
- the detection target point is reached when the first gear selection position or a second gear selection position different from the first gear selection position is present.
- a clutch for a vehicle with the features according to claim 10 is proposed to solve at least one of the aforementioned objects.
- Figure 1 A vehicle drive train with a clutch in a special
- Figure 2 A method for controlling a clutch in a special
- FIG. 1 shows a vehicle drive train with a clutch 10 in a special embodiment of the invention.
- the clutch 10 is effectively arranged between an internal combustion engine 12 and a transmission 14.
- the clutch 10 has a clutch input 16 connected to the internal combustion engine 12 and a clutch output 18 connected to the transmission 14.
- the clutch 10 can be dependent on a clutch actuation position
- Torque is transmitted between clutch input 16 and clutch output 18.
- Clutch actuation speed is controlled by an electrically
- Clutch actuator 20 can be influenced by a
- Clutch control unit 22 is controlled.
- the clutch actuation is carried out in an automated manner by the clutch actuation device 20.
- the transmission 14 can assume a shift position for changing a translation, which is dependent on a gear selection position 24 of a gear selection element 26, which is used to change the gear selection position 24 with a
- Gear selection speed taking place gear selection movement 28 can perform, which in turn can be effected by a person.
- Clutch actuation device 20 conducts when a first is reached
- the gear selection speed of the gear selection movement 28 is via the
- Position sensor 30 detects and the clutch actuation device 20 sets the clutch actuation speed during the clutch actuation process as a function of the detected gear selection speed. This allows the clutch actuation speed to be adapted to the driver's driving style. The clutch actuation speed is set proportionally to the gear selection speed. If the driver operates the gear selection element 26 at a higher gear selection speed, the
- FIG. 2 shows a method 100 for controlling a clutch in a special embodiment of the invention.
- the gear selection speed is determined in that the current gear selection position 102 is detected via the position sensor 30 and compared with a first stored gear selection position 104 previously stored in a memory M, the difference between the current and the first stored gear selection position 102, 104 is formed as first difference 106 and the amount of first difference 106 as first gear selection position change 108 is compared with a predetermined change threshold value 110. If the first gear selection position change 108 is greater than or equal to the change threshold value 110, a detection starting point 112 for detecting the gear selection speed is set.
- the change threshold value 110 can be fixedly predetermined during operation of the clutch or can be changed during operation of the clutch. If the first gear selection position change 108 is smaller than the change threshold value 110, the current gear selection position 102 is stored in the memory M.
- the current gear selection position 102 is also compared with a second stored gear selection position 114 stored in the memory M before the first stored gear selection position 104, the difference between the current and second stored gear selection position 102, 114 being formed as the second difference 116 and the amount of the second Difference 116 as the second
- Gear selection position change 118 is compared with the predetermined change threshold value 110. Only when the first or second gear selection position change 108, 118 is greater than or equal to the change threshold value 110 is the detection starting point 112 set for detecting the gear selection speed. Otherwise, the current gear selection position 102 is stored in the memory M. By storing the current gear selection position 102 in the memory M, the gear selection position 120 stored first is deleted from the memory M.
- Change threshold value 110 are compared, the detection start point 112 not being set until one of the n gear selection position changes is greater than or equal to change threshold value 110.
- the number of n gear selection position changes can depend on a memory size of memory M made available.
- the memory size can be fixed or variable.
- the memory size of the memory M can depend on an operating state of the vehicle and / or on driving conditions.
- Gear selection position difference 128 formed.
- the detection time difference 122 can be fixedly predetermined or variable.
- the gear selection speed 130 is calculated from the gear selection position difference 128 and the detection time difference 122 as the mean gear selection speed.
- the clutch operating device can then control the clutch operating speed at the
- the acquisition target point 124 can be reached when the first gear selection position, from which the clutch actuation device automatically initiates a clutch actuation process for manual shifting of the transmission, or a second gear selection position different from the first gear selection position is present.
