A sensor arrangement of a motor vehicle, the sensor arrangement having a sensor element emitting electromagnetic radiation in a measuring direction to determine a measurement signal, and a cover element disposed in front of the sensor element in the measuring direction and being an injection-molded plastic part permeable to the electro-magnetic radiation and having an outer side facing a vehicle environment and an inner side facing the sensor element, and a heating means comprising conductor tracks. The conductor tracks can be applied to a film formed to the inner side of the cover element during production of the cover element by injection-molding, the film with the conductor tracks thus forming an insert of the injection-molded cover element, the conductor tracks being located on the side of the film facing away from the sensor element.

A wiper device is provided. A boost control unit, if a duty ratio has reached an upper limit value determined in advance, and if the rotational speed of a motor is less than a target rotational speed, varies an advance angle and an energization angle associated with the energization of the motor in accordance with the target rotational speed. An overtemperature protection unit monitors a load state of the motor, and, upon detecting a high-load state, performs a first protection control for decreasing the rotational speed of the motor. A demagnetization protection unit, upon receipt of an operating signal from a wiper switch when the temperature detected by means of a temperature sensor exceeds a first threshold and the first protection control is being performed, performs a second protection control for fixing the advance angle and energization angle of the motor by prohibiting the operation of the boost control unit.

A lidar sensor may include: a transmitter configured to transmit laser; a receiver configured to receive reflected laser; a mirror rotating unit configured to rotate a mirror in a designated direction, the mirror serving to reflect the transmitted or received laser; a cleaning device driving unit configured to drive a cleaning device to remove foreign matters adhering to the cover of the lidar sensor; a signal processing unit configured to determine when or where the lidar sensor is covered and calculate a distance to an object; and a control unit configured to control the transmitter not to transmit a laser signal or control a rotational velocity or rotation time of the mirror at a point of time that the lidar sensor is covered by the cleaning device, and control detection or utilization of the received signal when the distance to the object is calculated.

When a first driver setting mode indicates an “OFF mode” or an “AUTO mode,” a VP accepts a light operation mode request from an ADK. When an operation is performed by a user, the VP changes an operation mode of a headlight in accordance with the operation by the user. When the operation by the user has not been performed, the VP changes the operation mode of the headlight in accordance with the light operation mode request.

Methods and systems for thermal management of sensors of a vehicle. The system includes a sensor that is attached to a vehicle, a temperature monitor configured to collect temperature data corresponding to the sensor, a processor, and a sensor cleaning subsystem. The sensor cleaning subsystem includes a cleaning fluid reservoir and a port that is positioned to direct cleaning fluid from the reservoir to the sensor.

Light obstruction can be detected using a light obstruction sensor. In one example implementation according to aspects of the present disclosure, a computer-implemented method includes receiving, by a light obstruction sensor, light being emitted by a light source, a light level being associated with the light, and the light source and the light obstruction sensor being disposed in a light assembly. The method further includes determining, by a processing device, whether the light level exceeds a first threshold. The method further includes, responsive to determining that the light level exceeds the first threshold, determining that the light being emitted by the light source is at least partially impaired by an object. The method further includes validating, by the processing device, the determination that the light source is at least partially impaired by the object to confirm whether the light source is at least partially impaired by the object.
