Abstract:
A method for determining an actuator path of a hydraulic clutch actuator, includes measuring a first temperature of the hydraulic clutch actuator with a first temperature sensor, measuring a second temperature of the hydraulic clutch actuator with a second temperature sensor, calculating a first temperature difference between the first temperature and the second temperature, using the first temperature or the second temperature as a clutch actuator temperature to determine a compensation value of the actuator path when the first temperature difference is less than a threshold value, and modifying the actuator path using the compensation value. In an example embodiment, the first temperature sensor measures a one of a circuit board temperature, an angle sensor temperature or a pressure sensor temperature, and the second temperature sensor measures another one of the circuit board temperature, the angle sensor temperature or the pressure sensor temperature.
