Abstract
Disclosed herein are system, method, and computer program product embodiments for cleaning one or more sensors of an autonomous vehicle (AV) system. For example, the system includes a tank to store a solvent. A heat exchanger is disposed in the tank to transfer heat from a heated fluid to the solvent. A first actuator is provided to enable and disable fluid communication of the heated fluid from a coolant system to the heat exchanger. A nozzle is in fluid communication with the tank to spray the solvent on a sensor of an autonomous vehicle (AV) system to remove debris. A controller is programmed to control the first actuator to enable the fluid communication of the heated fluid to the heat exchanger to increase at least one of a temperature and a pressure of the solvent within the tank.
