Abstract
Abstract An improved vehicle reverse control system having a power circuit for a starter motor for starting an engine. The circuit may include a control element for controlling the starter motor, in combination with separate control elements for starting the engine and for controlling reverse operation, at least one of which may be located on or near the operator's handle grip. The circuit may also include an element which detects reverse operation and an element which suppresses the starter motor whenever the vehicle is operated in reverse. The circuit may also include an element for detecting when the engine is operating and an element for disabling reverse operation of the starter motor when the engine is operating. The circuit may also include elements for suppressing engine start and for suppressing reverse operation, disposed so that the starter motor may be controlled for only one of the two operations at a time.
