A vehicle has an electric propulsion motor, a regenerative brake control and an anti-lock friction brake system which responds to excess wheel slip of a front wheel during braking to modulate friction braking torque to reduce the excess wheel slip. It further has a control responsive to activation of the anti-lock brake system to prevent the application of regenerative braking during such activation. The regenerative braking may be blended with the friction braking when anti-lock braking is not activated so that battery charge is conserved. When the anti-lock braking is activated, however, the regenerative braking is ramped down to preserve smoothness in the braking. The regenerative braking may be applied to create drag during vehicle coastdown. When anti-lock braking is activated, if it is sensed that the wheel is on a low friction (m

A vehicle having an electric power supply, a front wheel, an electric propulsion motor mechanically coupled to the front wheel and electrically coupled to the electric power supply, a control for applying coastdown regenerative braking to the front wheel when the vehicle is in a coastdown mode, and a hydraulically activated friction brake system with an anti-lock apparatus which, when activated, responds to excess wheel slip of the front wheel during braking to modulate hydraulic pressure and thus control braking torque to reduce the excess wheel slip, the control comprising, in combination: hydraulic pressure responsive means for determining when the front wheel is on a low friction road surface; and means for eliminating the coastdown regenerative braking when the anti-lock apparatus is active and the hydraulic pressure responsive means determines that the front wheel is on a low friction road surface but maintaining the coastdown regenerative braking when the anti-lock apparatus is active and the hydraulic pressure responsive means determines that the front wheel is not on a low friction road surface.
