Antijackknife/Antispinout Module

  We have designed a system that disables a semi-truck’s front-wheel brakes while the tractor is skidding sideward and steered in the direction of skid, allowing the front wheels to roll freely and restore alignment of the tractor with its trajectory.  Braking responds to the brake peddle normally when skidding stops or steering ceaces to be in the direction of skid.

The system consists of a control module mounted on the steering column and an effector valve in each front-brake hose, these with appropriate wiring.  The control module is equipped with a steering-direction sensor, a lateral-acceleration sensor and a relay.  The sensors pass current from the brake-light circuit to the relay trigger when inertia and steering are both rightward or when inertia and steering are both leftward.  The relay when so triggered passes current from the key-on circuit to both effector valves (left front and right front).  The activated valves block their respective brake hoses and deflate respective front-brake chambers.

We believe the module can be manufactured for less than $100 and installed for less than $200 and that it could sell for more than $500, considering the anxiety and danger associated with jackknifes and spinouts.  It is possible that the antijackknife/antispinout system can use the ABS valves.  Otherwise it would require two dedicated three-way valves.
