Abstract

A system for applying regenerative braking during high friction coefficient braking of a vehicle includes at least one controller; at least one braking sensor interfacing with the at least one controller; a vehicle powertrain interfacing with the at least one controller; a brake pedal interfacing with the at least one controller; vehicle friction brakes interfacing with the at least one controller; and the at least one controller applies anti-lock braking torque to the vehicle brakes and simultaneously applies regenerative braking torque to the vehicle powertrain responsive to input from the at least one braking sensor. A method for applying regenerative braking during high friction coefficient braking of a vehicle is also disclosed.

Description

technical field [0001] The illustrative embodiments of the invention relate generally to regenerative braking in a vehicle. More specifically, the illustrative embodiments of the present invention relate to a system and method for applying regenerative braking on a surface characterized by a high coefficient of friction during anti-lock friction braking. Background technique [0002] To improve fuel economy, some types of vehicles such as hybrid electric vehicles (HEVs) can be equipped with regenerative (regen) braking, wherein kinetic energy during braking is converted by an electric machine into storable energy which is then made available for propulsion. Regenerative braking is one of the enablers of hybrid vehicle technology. It has been found that regenerative braking can be used to achieve fuel economy improvements of 15% to 30% over vehicles that are capable of non-regenerative braking. [0003] An anti-lock braking system (ABS) is an automotive safety system that a...
