Wheel Optimized Brake Torque at the VE Mechatronic Brake

Conventional brakes commence with given brake torque distribution and abruptly change to wheel individual torque corrections when ABS-ESP intervenes. This leads to less than optimal braking, firstly around the transition from “given distribution” to individual ABS-ESP control and secondly when ABS-ESP switches from “locked” to “rotating”. Neither of these states offers the optimal deceleration. The VE mechatronic brake (EMB, electro mechanical brake) is designed to apply wheel individual braking with wheel optimized torques that give the best braking and stability from initial input to maximum deceleration, without sudden transition to ABS-ESP. With electric drive motors, a very rapid adjustable part of wheel individual torque can be combined with the individually controllable VE brakes.
