Overheating Protection

The overheating protection for the slide/tilt sunroof motor is calculated in the roof control module. To this end, a temperature sensor is mounted on the board in the roof control module to measure the ambient temperature.

The roof control module calculates the current temperature of the motor based on the running time of the slide/tilt sunroof motor.

The warm-up and cool-down periods are stored in a temperature model in the roof control module.

The current temperature is stored in the memory before the roof control module passes into sleep mode. The motor temperature is made equal to the ambient temperature when the vehicle is started again.
