An integrated jackknife control device for a tractor trailer assembly requires minimal if any modification to the existing fifth wheel coupler of the tractor trailer. The device comprises a computer controlled braking system including one or more pivot brakes acting directly on the trailer body, sensors which detect tractor trailer conditions indicative of incipient or full-fledged jackknifing and possibly other hazardous conditions such as collision or panic braking, and a proportional controller which causes one or more brake to apply a resistive force...
A braking system for inhibiting a trailer of a tractor trailer assembly from jackknifing, said trailer comprising an underframe which has a front end portion supported on said tractor and a rear end portion supported on wheels, said braking system comprising: (A) a source of pressurized fluid; (B) a proportional control valve having an inlet port connected to said source of pressurized fluid and having an outlet port, said valve being controllable to selectively pressurize fluid in said outlet port to a variable level ranging from 0% of a maximum pressur...
