Abstract
A computer is programmed to determine a target brake torque that is below a preset holding brake torque and at least high enough to hold a vehicle at standstill; and upon detecting that a brake of the vehicle is applied and a speed of the vehicle is below a threshold, monotonically reduce a brake torque of the brake so that the brake torque reaches the target brake torque when the speed reaches substantially zero.
