Abstract
A method for the determination of a motor voltage limit, wherein a clutch actuator of an automated shift transmission remains motionless, including the steps of (a) raising or lowering a withstand voltage by an increment ΔU, starting from a current withstand voltage (Ucurr), and (b) determining whether the clutch actuator moves under the changed withstand voltage.
Claims10
A method for the determination of a motor voltage limit, wherein a clutch actuator of an automated shift transmission remains motionless, comprising the steps:
- (a) raising or lowering a withstand voltage by an increment ΔU, starting from a current withstand voltage (Ucurr);
- and,
- (b) determining whether the clutch actuator moves under the changed withstand voltage.
A device for determining a motor voltage limit, where a clutch actuator of an automated shift transmission remains motionless, having a control system that is adapted to carry out a method for the determination of a motor voltage limit, wherein a clutch actuator of an automated shift transmission remains motionless, said device comprising:
- (a) a means for raising or lowering a withstand voltage by an increment ΔU, starting from a current withstand voltage (Ucurr);
- and,
- (b) a means for determining whether the clutch actuator moves under the changed withstand voltage.
