A pulse charging profile for a vehicle battery is synchronized with driver or vehicle demanded current disturbances by phase tracking the fundamental frequency of the desired pulse charging profile to those driver or vehicle demanded current disturbances. When these driver or vehicle demanded disturbances are not active, the tracked charging profile is honored.

A method for heating a battery in a hybrid electric vehicle. The hybrid electric vehicle has an engine, a battery, a motor generator powered by the engine or the battery, and a control module. The method includes the steps of determining a battery temperature and determining whether a tip-in event, a tip-out event, or a terminal voltage event has occurred. The polarity of the battery is reversed if the battery temperature is below a predetermined value and if a tip-in event, a tip-out event, or a terminal voltage event has occurred.

A method and system of engine state determination includes a plurality of requestors each of which compares vehicle or environmental conditions to a requirement and outputs a request state variable. The requestors are grouped according to function or component and the request state variables are combined and simplified at the output of each group. A state machine receives the final combined and simplified request state, and evaluates it according to the active or inactive status of the requests. The state machine carries out the proper state transition and outputs the desired engine state to engine control algorithms that start or stop the engine as necessary.

The present invention provides a method for reducing torsional vibration in a vehicle drivetrain. The method comprises detecting a rotational speed of the drivetrain to generate a rotational speed signal. The method also includes generating a vibration compensating torque command which is a function of a frequency content of the rotational speed signal. The present invention further provides a system for reducing torsional vibration in a vehicle drivetrain. The system includes a source of torque, a drivetrain coupled to receive torque from the source of torque and a speed detector adapted to detect a rotational speed of the drivetrain and generate a rotational speed signal. The system additionally includes an electronic controller coupled to the source of torque and programmed to provide operational command signals to the source of torque. The system further comprises a frequency detector having an input and an output, the input coupled in electrical communication with the speed detector to receive the rotational speed signal and the output coupled in electrical communication with the electronic controller.

A method of controlling electric motor torque in an electric vehicle for improved vehicle performance and energy conservation includes receiving a throttle torque request and a brake torque request, and sensing the speed of the vehicle. The brake torque request is split into a creep cancellation component and a brake regenerative component. The throttle torque request is adjusted based upon the creep cancellation component and the brake regenerative component to produce a torque sum. The electric motor torque is then controlled based upon the torque sum.
