<p>A brake control system for a motor vehicle having front and rear axles. A controller defining a brake map is provided for controlling vehicle deceleration in response to a braking request signal. The brake map defines a series limit threshold 230, 240 delimiting a first brake region A & B and a second brake region C & D. Within the first brake region, A & B, vehicle deceleration is performed at least substantially without front axle friction braking. Within the second brake region C & D, vehicle deceleration is performed by braking which includes front axle friction braking. The series limit threshold is profiled such that a transition from said first brake region to said second brake region varies with a dynamic operating parameter of the vehicle, preferably vehicle speed. A method defining a portion of the series limit threshold for rear axle braking 230 to approximate a maximum deceleration available from regenerative braking 240 is also disclosed.</p> |
