Title: HYBRID DRIVE TRAIN CONTROL METHOD
Abstract:
A control system for a hybrid vehicle utilizes telematics and on board sources to obtain information relating to operating conditions. The data is used to modify hybrid-electric drive train operation to extend the life of components of the drive train. In response to requests for propulsion, data relating to expected conditions of operation including one or more of the following, weather, traffic and road conditions, determines what proportion of the request to meet from the internal combustion engine and what proportion to meet from the electrical motor. The proportion of the request for propulsion allocated to the engine is increased where expected conditions of operation impose excessive stress on electrical components of the drive train.
