Method for deflation of hydraulic pressure reservoir of automated gearbox of motor car, involves performing time-controlled emptying of hydraulic system when pressure in reservoir falls below set threshold, or detects defective sensor

摘要

The method involves checking whether the pressure in the hydraulic pressure reservoir falls below a predetermined threshold and whether a defective pressure sensor is detected. The time-controlled emptying of the hydraulic system is performed when the pressure in the hydraulic pressure reservoir falls below a predetermined threshold, or a defective pressure sensor is detected. The hydraulic pressure reservoir is emptied when the driving time of the valves of the hydraulically operated clutch actuator reaches a given administered time.
