VEHICLE CONTROL SYSTEM AND METHOD

摘要

A control system for a vehicle (10) having an air braking system includes a supply line (13) for receiving a supply of compressed air for the air braking system. One or more brake members (19) are provided in fluid communication with the supply line (13) and controllable such that upon receipt of compressed air, the brake members (19) become disengaged to facilitate movement of the vehicle (10). Upon removal of the compressed air, the brake members (19) become engaged to prevent movement of the vehicle (10). An isolator device (20) is positionable within the supply line (13) upstream of the brake members (19) and is controllable to operate in a first state wherein the compressed air flows along a supply line (16) and a second state wherein the compressed air is prevented from flowing along the supply line (16) to the brake members (19).

1. A control system for a vehicle having an air braking system comprising:
a supply line for receiving a supply of compressed air for use in the air braking system; one or more brake members in fluid communication with the supply line and controllable such that upon receipt of a supply of compressed air the one or more brake members become disengaged so as to facilitate movement of the vehicle and upon removal of the supply of compressed air the one or more brake members become engaged so as to prevent movement of the vehicle; and an isolator device positionable within the supply line so as to be located upstream of said one or more brake members, the isolator device being controllable to operate in at least two states, a first state wherein the compressed air is permitted to flow along said supply line to the one or more brake members and a second state wherein the compressed air is prevented from flowing along said supply line to the one or more brake members; wherein when said isolator device is in the second state, any compressed air present in the supply line downstream of the isolator device but upstream of the one or more brake members is exhausted therefrom.
