摘要:
A method for operating a direct wiper drive having a motor, in particular for a windshield wiper, is described. The method comprises making available a limiting load torque for normal operation, determining at least a first characteristic variable for the plausibility of an exceptional case, determining at least a second characteristic variable for the reliability of an exceptional case, and deactivating the limiting load torque as a function of the first characteristic variable and the second characteristic variable.
摘要:
A system for determining if a tire of a vehicle is improperly inflated. The system includes a radar, a wheel speed sensor, and a controller. The radar is configured to emit a signal to detect a reflection of the signal off of an object positioned perpendicular to the vehicle, and to output an indication of a speed of the vehicle. The wheel speed sensor is configured to sense a speed of a wheel of the vehicle. The controller is configured to receive the indication of the speed of the vehicle from the radar, to calculate a speed of the vehicle based on the sensed speed of the wheel, and to determine a tire of the wheel is improperly inflated when the speed of the vehicle calculated using the wheel speed sensor varies by more than a predetermined amount from the speed of the vehicle determined using the radar signal.
