Abstract

PURPOSE:To improve safety during a start by a method wherein a steering angle detecting means for a handle and an engine starting circuit are interlinked, and operation of a starting circuit is not effected outside a given steering angle range. CONSTITUTION:During the starting of an engine, an ON-switch 2 is first pressed to transmit a request signal radio wave from a transmitting and receiving circuit 19 for a given time. The signal is received by a card type memory code transmitter 18 carried by a driver with himself. In response to receipt of the signal, a specified code is transmitted from the memory code transmitter 18, and the signal is received by the transmitting and receiving circuit 19. The signal is collated with a set code in a code collating circuit 20, and when they coincide with each other, a source circuit 21 for running is turned ON. A handle lock unlocking switch 5 is then pressed, and when a starting switch 8 is pressed in a state that handle lock is released from locking, it is decided from an output from a steering angle sensor 12 whether or not a handle is in a position where locking is impracticable. When it is in the position, the starting of an engine is blocked.

Description

[Detailed description of the invention] [Purpose of the invention] <Industrial Icheon field> The present invention relates to a starting control device for a motorcycle.

BACKGROUND OF THE INVENTION Conventionally, a common mechanical key has been used to lock a handlebar of a motorcycle and a key switch that turns on and off a power supply circuit including a starting circuit. The handle lock device is integrated with the main switch and has a mechanism that prevents the power from being turned on unless the handle lock is completely released. Therefore, to start the engine, it is necessary to unlock the handle using a mechanical key, turn on the power at the same time, and then press the starter switch to start the engine.

<Problems to be Solved by the Invention> As a result, key operations for unlocking the handle lock are complicated, and the fail-safe function for engine starting operations is also complicated.

The present invention has been made to eliminate such inconveniences, and its main purpose is to automatically achieve fail-safe engine starting operation and to complete engine starting operation in a short time. The object of the present invention is to provide a possible starting control device.

[Structure of the Invention] <Means for Solving the Problems> According to the present invention, the object is to include a steering wheel turning angle detection means, and to connect the output of the detection means to an engine starting circuit. This is achieved by providing a starting control device for a motorcycle, characterized in that the starting circuits are made to cooperate with each other and become inoperable outside a predetermined steering angle range.

<Operation> By doing this, the starting circuit will not operate when the steering wheel is turned by a predetermined angle or more and is in the lockable position, so the engine will not operate with the steering wheel locked or with the steering wheel turned. A failsafe for disabling the starting operation can be easily achieved.
