Abstract
Methods and systems are provided for controlling a radar system in a vehicle. In particular, the method and system employs a heating element within or affixed to a portion or proximate to a vehicular radar sensor and where the method and system is operative to determine that a blockage of the vehicular radar sensor has occurred and that an icing condition may exist, and to activate the heating element in response.
Claims20
A method comprising:
- generating a first control signal to activate a sensor;
- receiving a first error signal indicating a failure of the sensor to activate;
- generating a second control signal to activate a heating element integrated proximate to the sensor;
- receiving a data indicating an activation of the sensor;
- and
- controlling a vehicle system in response to the data.
3 more elements
An apparatus comprising:
- a sensor for transmitting and receiving a sensor signal and for generating a data in response to the sensor signal, the sensor further operative to generate a first error signal in response to an error condition;
- a heating element proximate to the sensor;
- a vehicle controller for controlling a vehicle system in response to the data;
- and
- a sensor controller for generating a first control signal to activate the sensor, for receiving the data, for receiving the first error signal, for generating a second control signal to activate the heating element integrated proximate to the sensor, and for coupling the data to the controller.
