Abstract
A parking braking system for a brake in a vehicle wherein, upon moving a parking brake selector to a park position, the brake is arranged to be mechanically locked or latched into place by means of a variable position park latch mechanism which is adapted to co-operate with an operating member of the brake so as to set the park load on the brake at a desired level. The parking braking system includes a control system which has a brake level determining means (134) to determine the brake load level at which the brake is to be parked and a control means (136) for controlling the actuation of the latching mechanism, or a combination of several latching mechanisms, to selectively maintain that brake load level during a parking phase. In order to determine the park load level to which the brake should be applied in a given situation, there is provided a static mode 1 which generates a signal representative of the static condition of the vehicle or a static compensation signal.
