In a vehicle equipped for regenerative and non-regenerative braking, regenerative braking only is applied to predetermined wheels in response to braking demand when the driver attempts to slow the vehicle at a first rate (< D1 ft/sec2), no wheel locking on any braking wheel as indicated by an anti-lock braking system controller and speed exceeds a minimum threshold. If braking is applied in a turn, appropriate amount of non-drive wheel service/foundation brake torque to maintain vehicle stability is applied. The appropriate amount of foundation braking to be applied is determined by the amount of vehicle yaw, steering wheel input and vehicle speed by using a look-up table. As braking demand increases foundation/service braking is added, first to any wheels not providing for regenerative braking and later to wheels having regenerative braking. |
