Abstract
A wiper system for vehicles is provided. The system includes a heated wiper blade assembly, a heated cowl assembly and a controller. The controller receives input from one or more sensors or systems and causes a power source to provide, reduce or stop power to heating elements in the blade and/or cowl depending upon sensed conditions. At least some components in the assembly comprise thermally conductive polymers. The system provides surprisingly advantageous results in that it is effective for melting and clearing ice and snow with a lower than expected pull on a power source such as a battery.
Claims10
A windshield wiper system, comprising:
- a wiper assembly, the wiper assembly including a first heating element in electrical communication with a power source;
- a temperature sensor for detecting an ambient temperature;
- an engine status sensor system for detecting an at least two indicators of engine status from the group comprising crank shaft position, voltage, tachometer reading, vibration, accelerometer reading, and hall effect;
- and
- a controller for controlling a power supply from the power source to the heating element, wherein the controller is configured to receive input from the temperature sensor and the engine status sensor system and the controller controls the power supply in response to a set of sensed information, the set of sensed information including the ambient temperature and the at least two indicators of engine status.
