Abstract:
1. An electronic control system for a motor vehicle brake system comprising a charge system, a primary supply circuit, a secondary supply circuit, a tractor parking/emergency supply circuit and a trailer parking/emergency supply circuit, the electronic control system comprising: a housing having an input port in communication with the charge system, a first exhaust port in communication with the primary supply circuit, a second exhaust port in communication with the secondary supply circuit, a third exhaust port in communication with the tractor parking/emergency supply circuit and a fourth exhaust port in communication with the trailer parking/emergency supply circuit; a first solenoid disposed within said housing, said first solenoid selectively allowing communication between the charge system and the primary supply circuit via the input port and the first exhaust port in response to first electrical signals; a second solenoid disposed within said housing, said second solenoid selectively allowing communication between the charge system and the secondary supply circuit via the input port and the second exhaust port in response to second electrical signals; a third solenoid disposed within said housing, said third solenoid selectively allowing communication between the charge system and the tractor parking/emergency supply circuit via the input port and the third exhaust port in response to third electrical signals; a fourth solenoid disposed within said housing, said fourth solenoid selectively allowing communication between the charge system and the trailer parking/emergency supply circuit via the input port and the fourth exhaust port in response to fourth electrical signals; an electronic control unit in communication with said first solenoid, said second solenoid, said third solenoid and said fourth solenoid; a dash control assembly disposed on a dash of the motor vehicle, said dash control assembly in electrical communication with said electronic control unit via electrical cabling; and wherein electrical control signals are generated by said dash control assembly in response to an operator's manipulation of said dash control assembly, are communicated to said electronic control unit via the electrical cabling, and are used by the electronic control unit to generate the third electrical signals and the fourth electrical signals to control operation of said third solenoid and said fourth solenoid.
