Abstract:

A speed interlock can prevent a sliding fifth wheel on a vehicle from being unlocked while the vehicle is moving faster than a threshold speed. A processor, such as the vehicle's electronic control unit, advantageously monitors the vehicle speed and a switch that controls the fifth wheel slide, preventing the fifth wheel from being unlocked if the vehicle speed is above a threshold.
