Abstract
A trailer includes a chassis having a hitch, an axle having a tractive element rotatably coupled to the chassis, and an actuator coupled to the chassis and positioned to steer the tractive element in response to an input, the input varying based on at least one of a speed, a transmission gear, and a steering mode of a tractor vehicle.
Claims20
A trailer, comprising:
- a chassis having a hitch;
- an axle having a tractive element rotatably coupled to the chassis;
- and
- an actuator coupled to the chassis and positioned to steer the tractive element in response to an input, the input varying based on at least one of a speed, a transmission gear, and a steering mode of a tractor vehicle.

A steering control system for a trailer, comprising:
- an axle having a tractive element rotatably coupled to a chassis;
- an actuator positioned to steer the tractive element;
- and
- a processing circuit configured to:
- evaluate at least one of a speed, a transmission gear, and a steering mode of a tractor vehicle;
- and
- engage the actuator to steer the tractive element according to a control strategy that varies based on at least one of the speed, the transmission gear, and the steering mode of the tractor vehicle.
4 more elements
A method of steering a trailer comprising:
- identifying an operating state of a tractor vehicle with a processing circuit;
- steering a tractive element with an actuator when the operating state relates to a first mode of operation of the tractor vehicle;
- and
- centering the tractive element with the actuator when the operating state relates to a second mode of operation of the tractor vehicle.
