Abstract
An automated axle control system provides both indication to the driver when a lift axle should be raised or lowered, and takes action to effect axle positioning when the driver fails to respond. Operations are based on estimates of vehicle weight and vehicle speed and are implemented primarily through preexisting vehicle controllers and a controller area network over which the controllers communicate.
