Abstract: A braking system 12 for use with an electric vehicle 10 including an electric motor/generator assembly 14, and a conventional electrical energy storage device 16. Motor/generator 14 selectively drives wheels 20 of vehicle 12. The braking system 12 includes a motor control module 26 which is communicatively coupled to motor/generator 14 and which selectively causes motor/generator 14 to provide a regenerative braking function at wheels 20 of vehicle 10. Braking system 10 further includes an antiskid braking system which selectively provides friction braking at wheels 20 and 24 of vehicle 10. The braking system 12 is effective to detect antiskid braking events at each of the wheels 20, 24, to selectively provide an antiskid braking function at each of wheels 20, 24 where the antiskid braking events are detected, and to selectively disable the regenerative braking function only when an antiskid braking event is detected at either of wheels 20.

Abstract: Strategies other than immediate elimination of regenerative braking (FIG. 2) are invoked when an incipient wheel lock-up is detected, the ABS becomes active, and/or incipient wheel slip is detected. The strategies include: reducing the regenerative braking torque as a function of the coefficient of friction of a surface on which the vehicle is traveling (FIG. 3); and adjusting regenerative braking in relation to the rate at which wheel slip is changing (FIG. 4). Some of the strategies may be applied on an individual wheel basis (FIG. 5), and some of the strategies may be applied in conjunction with operating friction brakes of the vehicle to apply at least some of the reduction in regenerative braking torque as friction brake torque (FIG. 1).
