Abstract

Braking system determines a brake actuation rate .DELTA.U/.DELTA.t, where U is a function of pedal position S, and compares the rate to a limiting value G. When G is not exceeded, the auxiliary brake is actuated first and the friction brake is actuated with a small slope. When G is exceeded, the friction brake is actuated sooner and with a greater slope, and the auxiliary brake may not be actuated at all.
