Abstract:
A controller for a vehicle having an engine, a generator connected to the engine, an electrical motor connected to the vehicle drive shaft and a battery electrically connected to the generator and the electrical motor, comprising,sensors to detect operational conditions of the vehicle, and a microprocessor programmed to: calculate a first parameter showing a target output of the electrical motor based on operational conditions of the vehicle; calculate a second parameter showing a target output of the engine based on the first parameter; calculate a third parameter showing a target rotation speed of the generator based on the second parameter; calculate a fourth parameter showing a generated output of the generator based on the second parameter; calculate a fifth parameter showing a target output of the electrical motor by limiting the first parameter in response to the fourth parameter; control the operation of the engine based on the second parameter; control the operation of the generator based on the third parameter; and control the operation of the electrical motor based on the fifth parameter.
