Control mechanism for an electric generator motor in an internal combustion engine

摘要

A control mechanism for an electric generator motor which can prevent excessive charging and insufficient capacity of an electrical power storage device includes a controller controlling operation of the electric generator motor when a total of restorable electrical power calculated on the basis of vehicle state and a present capacity of the electrical storage device is smaller than a specified reference capacity. The control mechanism effects a motor operation, i.e., application of torque, of the generator motor within a range in which the capacity of the electrical storage device does not fall below a specified minimum charge level required for driving vehicle auxiliary devices. The control mechanism effects motor operation of the electric generator motor with continuously changing restorable electrical power which has a positive correlation with an effective amount of depression of a brake pedal. The control device effects application of torque using the motor generator when a total of restorable electrical power is larger than a specified minimum capacity value.
