Definitions
- the present invention relates to a method for adapting the clutch characteristics in a double clutch system.
- the electromechanical clutch actuator can be divided into three components, particularly in automated manual transmissions.
- the first component relates to the clutch actuator, which comprises a drive unit regulated by the control software, which is, for example, an electric motor and a displacement unit.
- the second component is a clutch release, which transfers the release force of the drive unit to the plate spring of the clutch.
- the third component relates to a transmission system for transmitting mechanical forces between the clutch actuator and the clutch release.
- the transmission system includes a lever mechanism, a mechanical shaft and / or hydraulic lines, etc.
- the clutch can be actuated by moving to a specific position of the drive unit of the clutch actuator.
- the clutch release mechanism is actuated by the transmission system and the clutch is either closed or opened or a specific torque is set.
- the position of the drive unit can preferably be monitored with absolute displacement sensors.
- the conversion to a transmitted clutch torque is calculated in the control software using the clutch characteristic curve in which the transfer function "torque over the master cylinder travel" is stored.
- the object of the present invention is to provide a method for adapting the clutch characteristics in parallel shift transmissions, by means of which a correction of the transmission behavior of clutches in double clutch systems or parallel shift transmissions is possible.
- a method for adapting the clutch characteristics in a double clutch system which has a first clutch in a first branch and a downstream first sub-transmission and in a second branch have a second clutch and a downstream second sub-transmission, the first and second branches being connectable on the input side to a prime mover and on the output side to the vehicle wheels of a vehicle, and wherein the first clutch is connected by a first clutch actuator and the second clutch by a second
- Clutch actuators are operated.
- a zero point adjustment of the path measurement of the first and / or second clutch actuators is carried out according to a predetermined strategy as a function of predetermined criteria.
- the main advantage is that the method according to the invention takes into account not only the clutch properties but also the influences of the release system by adapting or zeroing the displacement measurement.
- the changes in the transmission behavior of the lever system of the transmission system of the clutch actuator, or changes in the volume of a line of the transmission system of the clutch actuator, which is filled with hydraulic fluid can be compensated for, for example, by temperature changes.
- the zero point adjustment is carried out on the first clutch or performed on the second clutch.
- the active first clutch or the active second clutch transmits a torque when the gear is engaged and in which the second sub-transmission or first sub-transmission downstream of the passive second clutch or the passive first clutch Gear is selected and then the zero point adjustment of the first clutch (A) and the second clutch (B) and the reinsertion of the same gear are carried out.
- first clutch and the second clutch are designed with gears designed downstream first partial transmission and second partial transmission of the zero point adjustment of the first clutch and the second clutch is carried out.
- the zero point adjustment can be carried out when the vehicle is stationary and the gear is in the first sub-transmission or second sub-transmission downstream of the first clutch or the second clutch and the gear is engaged in the second sub-transmission or first sub-transmission downstream of the second clutch or the first clutch the first clutch or the second clutch, the gear of the second clutch or the first clutch connected downstream of the second clutch or the first clutch, the zero point adjustment of the second clutch or the first clutch and the same gear of the second clutch or the first clutch second sub-transmission or first sub-transmission can be reinserted.
- Clutch and the second clutch downstream first sub-transmission and second sub-transmission advantageously also possible to carry out the disengagement of the gear of the first sub-transmission or second sub-transmission downstream of the first clutch or the second clutch, then carry out the zero point adjustment of the first clutch and the second clutch and the same gear of the first sub-transmission or the second sub-transmission.
- the implementation of the zero point adjustment is repeated at certain time intervals under valid entry conditions.
- the first clutch or the second clutch can advantageously be adapted first, the last successful zero point adjustment of which was the longest ago.
- the zero-point adjustment is always carried out on the first clutch or the second clutch, the gear of which is most likely to be used for starting. This takes into account the fact that the moment of this first clutch or second clutch determines the comfort of the subsequent approach.
- zero point adjustments are always carried out simultaneously in the first clutch and the second clutch. Annoying noises, which can be traced back to the layout of the gears while standing, are minimized if both gears are laid out at the same time and the zero point adjustment is then carried out.
- the clutch characteristic curve can advantageously also be adapted by a tactile point adaptation.
- the position of the clutch actuator at which the clutch begins to transmit a minimal torque is determined. This adaptation can be done while standing
- Vehicle that is, when the foot or hand brake is applied, be carried out with the gear engaged and the engine idling.
- the clutch is slowly closed until a minimal torque is transmitted.
- the idle controller of the engine control reacts to the clutch closing by increasing the engine torque by exactly the amount of the transmitted clutch torque (3 - 4 Nm), so that the
- Idle speed remains constant.
- the transmitted torque of the clutch and thus the position of the touch point can be determined and adapted based on the reaction of the engine torque.
- the following particularly advantageous strategies are conceivable for the touch point adaptation each time the vehicle is stationary. If a gear is engaged in the first and second partial transmissions, the touch point adaptation is carried out in succession. If a gear is engaged in the first sub-transmission or second sub-transmission downstream of the first clutch or the second clutch and no gear is engaged in the second sub-transmission or first sub-transmission downstream of the second clutch or the first sub-transmission, a gear is engaged in the second sub-transmission or in the first sub-transmission Gear engaged and the touch point adaptation for the first clutch and the second clutch performed simultaneously.
- a touch point adaptation can expediently also be carried out in such a way that the clutch is always first adapted, the last successful touch point adaptation being the longest ago.
- a tactile point adaptation can advantageously always be carried out first on the clutch which is connected upstream of the sub-transmission in which the gear for starting is most likely to be engaged.
- Figure 1 is a schematic representation of a block diagram of a
- FIG. 2 is a flowchart for the touch point adaptation.
- the influences of the release system must be taken into account by adapting or adjusting the zero point of the distance measurement.
- the transmission behavior of a lever system of the transmission system can change due to temperature changes electromechanical clutch actuators change or can the volume of a
- Path measurement can be carried out. This can be carried out by moving to a certain, excellent position of the clutch, which can be recognized by the clutch actuator as soiche. This position can be, for example, the pressure point of the
- This zero point adjustment can be carried out while driving with the clutch engaged and the gear engaged, or while stationary with the gear engaged.
- the clutch is closed briefly.
- the clutch characteristic can also be adjusted using the touch point adaptation.
- the position of the clutch actuator at which the clutch begins to transmit a minimal torque is determined. This adaptation can be done with the vehicle stationary, i.e. So with foot or handbrake applied, with gear engaged and engine in
- the internal combustion engine M transmits a torque T to the input shaft E of the parallel transmission PSG and thus to a first input shaft E1, which is connected to a first clutch A, and a second input shaft E2, which is connected to a second clutch B.
- the clutch A is connected to a partial transmission iA, which usually shifts the odd gears 1, 3 and 5.
- the clutch B is with a Partial gearbox iB connected, which switches the even gears 2, 4 and possibly the reverse gear.
- the output shaft A1 of the partial transmission iA and the output shaft A2 of the partial transmission iB are jointly connected to the vehicle wheels F via the output shaft A of the parallel gearbox PSG.
- a clutch A or B When driving, a clutch A or B is closed and transmits the engine torque to the output shaft A via an engaged gear of the downstream sub-transmission iA or iB.
- the other, passive clutch B or A is then either open when the downstream sub-transmission is in gear or when the gear is disengaged of the downstream sub-transmission closed.
- the torques transmitted by clutches A and B are controlled by two independent clutch actuators KA and KB.
- the zero point adjustment can be carried out as follows:
- Partial gearbox iB or iA is designed to disengage the gear of the partial gearbox iB or iA.
- the zero point adjustment of the clutches A and B is carried out and then the same gear of the partial transmission iB or iA is re-engaged.
- Part gearbox iB or iA is reinserted.
- the touch point adaptation can be carried out one after the other.
- clutch A or B should always be adapted first, the last successful touch point adaptation being the longest ago. 4.
- the touch point adaptation is always carried out on clutch A or B, which is connected upstream of the sub-transmission iA or iB in which the gear for starting is most likely to be engaged.
