Abstract
A slow in turn system for a vehicle comprises an accelerator linkage that is linked to the input lever of a variable speed transmission. The accelerator linkage includes first and second link arms that couple a foot pedal to a rotatable cam plate. The link arm that connects to the cam plate is coupled thereto by a slider so that the connection point of that link arm may be moved towards and away from the pivot axis of the cam plate. The slider is moved away from the pivot axis of the cam plate during turns of the vehicle to reversely rotate the cam plate, and hence retard the input lever of the speed changing system, to thereby automatically slow the vehicle. This movement of the slider is accomplished by a connecting linkage extending to the steering system of the vehicle. In addition, the vehicle includes a cruise control system that can be set to obtain a particular forward speed but which allows the operator to temporarily speed up without subsequently having to reset the cruise control system. The slow in turn system works without affecting the position of the accelerator foot pedal and without requiring the cruise control system to be disengaged.
