Abstract
A control system for a heavy-duty vehicle such as a dump-type straight truck includes a portable radio frequency transmitter and a radio frequency receiver. The radio frequency receiver is operatively connected to a vehicle device or assembly which performs a function such as operation of the vehicle dump bed or raising and lowering of the vehicle axle/suspension system, so that the function can be controlled from the cab of the vehicle by the radio frequency transmitter, and whereby the function occurs substantially instantaneously due to the use of radio frequency and eliminates the need for a custom hard-wired control system.
