REGENERATION STRATEGY FOR A VEHICLE HAVING DECOUPLED FRONT AND REAR AXLE DRIVE ACTUATORS

摘要

A method of controlling a vehicle having a first axle driven by an internal combustion engine, and a second axle independently driven by an electric device includes determining if the accelerator pedal is disposed in a depressed position or in a non-depressed position, and determining if a brake pedal is disposed in a depressed position or in a non-depressed position. An axle control strategy for controlling energy regeneration of an energy storage device is selected based on the position of the accelerator pedal being in either the depressed position or the non-depressed position, and the position of the brake pedal being in either the depressed position or the non-depressed position. A control signal is communicated to at least one of the first axle or the second axle to implement the selected axle control strategy.

主权项

1. A method of controlling a vehicle having a first axle driven by an internal combustion engine, a second axle driven by a second power source, and an energy storage device, wherein the internal combustion engine and the second power source are mechanically independent of each other and do not directly communicate torque to each other, the method comprising:
sensing a position of an accelerator pedal to determine if the accelerator pedal is in a depressed position, or if the accelerator pedal is in a non-depressed position; sensing a position of a brake pedal to determine if the brake pedal is in a depressed position, or if the brake pedal is in a non-depressed position; selecting an axle control strategy, with a vehicle controller, to control energy regeneration of the energy storage device based on the position of the accelerator pedal being either the depressed position or the non-depressed position, and the position of the brake pedal being either the depressed position or the non-depressed position; and sending a control signal from the vehicle controller to at least one vehicle component to implement the selected axle control strategy.
