However, in the conventional system described above, whether or not speed limiting operation is possible is determined only by turning on or off the switching means of the speed detection circuit, so that general users cannot use the wire that connects the speed limiting circuit and the speed detection circuit. There is a problem in that the speed limit function can be canceled extremely easily simply by disconnecting or grounding.

Therefore, the present invention provides a speed detection circuit that is provided in a speedometer and includes a series circuit of a voltage drop element and a switching means that turns off at a set vehicle speed or higher at which speed should be limited;
A speed limiting circuit that performs a speed limiting operation when the voltage from the speed detecting circuit is outside a predetermined range; and a speed limiting circuit that is provided in this speed limiting circuit and applies a bias voltage to a series circuit of the switching means and the voltage drop element. and a bias circuit for applying the voltage to the vehicle, and the bias voltage of the bias circuit is set to a value that causes the voltage of the speed detection circuit to fall within a predetermined range when the switching means is turned on. .

Furthermore, the switching means is configured to turn off even when the vehicle speed is low, and turn on from higher vehicle speeds until reaching a set vehicle speed at which the speed limit should be applied. When the switching means of the speed detection circuit is turned off, and when a general user disconnects or grounds the wire connecting the speed limit circuit and the speed detection circuit, the voltage from the speed detection circuit may fall outside the specified range. Therefore, the speed limiting circuit performs the speed limiting operation. Further, when the vehicle speed is lower than the set speed and the switching means of the speed detection circuit is turned on, the bias voltage of the bias circuit causes the voltage of the speed detection circuit to fall within a predetermined range, so that the speed limiting circuit does not perform the speed limiting operation.

In addition, if the switching means is turned off even when the vehicle speed is low, and turned on from higher vehicle speeds until reaching the set vehicle speed at which the speed limit should be applied, the speedometer drive wire will break and the speedometer will change to zero. It is also possible to maintain the vehicle speed limiting function by turning off the switching means even when the vehicle speed is reached. Further, even if the voltage from the speed detection circuit is outside a predetermined range, the vehicle speed limiting function can be canceled when the engine speed is less than a set value.
