Abstract
A proximity-detection and speed-control system for a materials-handling vehicle, such as a lift truck, is provided with a recommended direction of travel for the vehicle. A proximity sensor is provided to determine the vehicle's proximity to a restricted member, such as another vehicle, a high-value object, a dangerous location, or a pedestrian. If the vehicle is traveling in the recommended direction of travel, the speed control function is disabled. If, however, the vehicle is not travelling in the recommended direction and the proximity sensor indicates the vehicle is within a restricted distance of the restricted member, the speed control function is triggered to restrict the maximum speed of travel of the vehicle and to slow the vehicle if needed.
