Abstract
A start-assist system provided in a vehicle having two rear shafts, one of which is a drive axle, includes a control device having an air actuator attached to the drive axle; a level sensor for detecting loads applied to the shaft axles; an air supply source for supplying compressed air to the air actuator; a first valve disposed in an air conduit for supplying air to the air actuator; a second valve for releasing air from the air actuator; and a controller for controlling the first valve and the second valve. The a controller opens the first valve to introduce air to the air actuator when a signal from the level sensor indicates that the vehicle is stopped and is unladen, and opens the second valve to release air from the air actuator when the signal from the level sensor indicates that the vehicle is stopped and parking brake is activated.
