Method of adjusting an automatic parking brake

Torna indietro

Abstract

The method involves preloading a spring device comprising a helical spring e.g. disc spring, of an automatic parking brake. The preloading load is adjusted to a level corresponding to a minimum braking force required for immobilizing a motor vehicle. The adjustment step includes the indirect measurement of the braking force by measuring supply current of an electric motor, and the locking of the brake when the force is greater than a force of equivalent value with the pre-load. An independent claim is also included for an automatic parking brake system applying the automatic parking brake control method.
