Abstract
A control system for a vehicle sensor cleaning system is provided. The control system includes: a microcontroller configured to: receive inputs including at least one input from any one of the following sources: sensors, other controllers, and an operator; determine whether a signal to actuate a cleaning system for a sensor should be generated; analyze whether the signal should be delayed; sending an actuating signal to a sensor cleaning system if the controller determines that predetermined cleaning criteria are met and delays sending the actuating signal if the controller determines delay criteria are met. A method of controlling a sensor washing system may also be provided. The method includes: inputting signals from at least two sensors into a controller; weighing the inputted signals, wherein one of the signals is associated with a location of the vehicle on which the sensor washing system is located; determining whether to send a signal to actuate a sensor cleaner depending upon the weighing of the inputted signals; and sending a signal to the sensor cleaner to clean a sensor.
