SYSTEM AND METHOD FOR REMOTELY MANAGING CLIMATE CONTROL SYSTEMS OF A FLEET OF VEHICLES
The method simultaneously manages climate control systems of a fleet of vehicles at a fleet server remote from the vehicles. The fleet server has one or more processors and memory storing one or more programs for execution by the processor(s). Initially, at least one parameter relaying information about performance of a climate control system of a respective vehicle is received, from each vehicle. Each vehicle's climate control system includes at least an electrically driven compressor. The system then determines whether a performance inefficiency exists for the climate control system of at least one vehicle based at least in part on the parameter(s) received from the at least one vehicle. Upon determining that a performance inefficiency exists, an efficient operational setting that reduces the performance inefficiency is determined. Finally, an operational setting instruction is transmitted to the at least one vehicle to control the climate control system of that vehicle.
