초록 ▼

A trailer braking system for a towing vehicle has a trailer braking valve (26) is fed with a pressurized air supply which is modulated by the opening of the valve, as controlled by a first control pressure regulated by a trailer braking controller (24) in accordance with braking demand signals, to produce a trailer braking pressure. In order that a trailer braking pressure may be generated even if the above trailer braking valve control fails, the valve is supplied with a second control pressure independently of the first, and which is also capable of operating the trailer braking valve (26). In a preferred embodiment, the second control pressure is supplied from a braking line of the towing vehicle, such that the “back up”control pressure is a function of the towing vehicle braking.

대표청구항 ▼

A trailer braking system for a towing vehicle, comprising: transducer means for generating electrical braking demand signals in response to a demand; trailer braking control means adapted to receive said electrical braking demand signals and to produce an electrical control signal which varies with the braking demand; means for producing a control pressure in response to the control signal in order to regulate a trailer braking valve whose opening is regulated by said control pressure and which thereby modulates a pressurized air supply to the valve to generate a trailer braking pressure; means for supplying a back-up control pressure simultaneously with said control pressure to regulate the opening of said valve; and means for comparing said control pressure and said back-up control pressure and for enabling actuation of said trailer braking valve by said back-up control pressure when the difference in values between the control pressure and the back-up control pressure indicates insufficient braking by the control pressure.
