Abstract

A computer-implemented method controls at least one park brake relay valve (64) of a park brake system (66) of a vehicle (20), via control signals (S₅₁) sent to a park brake control unit (62), which controls the park brake relay valve, based on requests signals (S₅₂, S₅₄, S₅₆) received from at least one requester (52, 54, 56). The request signals take either an activated value, when the request is presented, or a neutral value, when the request is not presented. The request signals are sent with a given signal frame. The method comprises a safety check performed, when a request signal (S₅₂, S₅₄, S₅₆) is received, by a request arbitrator (70) to assess if the request is valid, by determining whether or not the request signal is longer than a first predetermined time-period (Δt1) and whether or not, during a second predetermined time-period (Δt2), the request signal takes the neutral value.
