Vehicle compartment and engine preheating system and method

摘要

The present invention involves a system and method of preheating a vehicle engine during non-use of the vehicle. The method includes receiving a programming input defining a minimum engine coolant temperature of a preheating strategy, initializing the preheating strategy based on the programming input, and sensing an energy source of the vehicle to run the preheating strategy. The method further comprises sensing an engine coolant temperature of the vehicle at a first time period, activating the preheating strategy to heat the engine if the engine coolant temperature is lower than the minimum engine temperature. The method further includes receiving feedback indicating the engine coolant temperature at a subsequent time period and deactivating the preheating strategy if the engine coolant temperature is greater than the maximum temperature at the subsequent time period.
