Abstract
A relatively simple electromechanical cruise control for a vehicle includes a hydrostatic drive linkage having a flat portion connecting two links and extending adjacent an electromagnet fixed to the frame of the vehicle. Actuation of the control under preselected operating conditions activates the electromagnet to hold the flat portion stationary and thereby maintain a given hydrostatic control position. Interlock circuitry deactivates the magnet if the operator touches the brake, leaves his seat or turns off either the cruise switch or ignition switch.
