Abstract

The circuit has pressure and position sensors connected with corresponding hydraulic actuators e.g. hydraulic cylinders. An anti-pinching device has pressure measuring units (13, 14) to measure pressure detected by each pressure sensor based on a position of the corresponding actuator. A comparison unit (16) compares values of the measured pressure with reference pressure values (18) according to the positions of the actuators. A deciding unit (17) decides whether to trigger an alarm or to stop or reverse the movement of a retractable roof and a rear boot lid based on the comparison result.
