Description

[Detailed description of the invention] (Industrial application field) This invention is an auto-cruise device used for motorcycles, etc., which reliably releases the auto-cruise device by forcibly returning the accelerator grip during auto-cruising. This relates to an accelerator device with auto-cruise used for.

(Prior art) Conventionally, auto cruise devices installed on motorcycles automatically control the vehicle speed to a constant level without turning the accelerator grip when the vehicle speed is set to a desired speed while driving the motorcycle. This is a device that can maintain speed. This auto-cruise device has the advantage of reducing driver fatigue and reducing fuel consumption of the two-wheeled vehicle when continuously driving at a constant speed on well-maintained roads such as expressways.

The configuration of a conventional constant speed traveling device for two-wheeled vehicles compares the set vehicle speed of a memory circuit, which is set by a speed command signal supplied based on the vehicle speed desired by the driver, and the actual vehicle speed of the two-wheeled vehicle. A signal is supplied to each valve of the actuator to increase or decrease the speed based on the difference between the set vehicle speed and the actual speed, and the opening degree of the throttle valve is adjusted by this actuator.

In such an auto cruise device for a two-wheeled vehicle, a set signal is supplied to the control circuit, and when the vehicle speed reaches a preset vehicle speed, auto cruise is automatically maintained, and a release signal is supplied to the control circuit. The auto cruise is canceled when In this case, the release signal input to the auto-cruise device is supplied by a forced return operation of a brake lever, brake pedal, clutch lever, accelerator grip, or the like. Specifically, for example, when the vehicle speed reaches a set lower limit vehicle speed (for example, 40 to 50 km/h) due to control operations of the brake lever, brake pedal, etc., it is detected as an electrical signal from a switch in the speedometer. This will cancel auto cruise. On the other hand,
When the clutch is disengaged by squeezing the clutch lever, the engine changes from a loaded state to an unloaded state, and the engine speed increases to a high level, putting the engine in a dangerous state of overspeeding. Therefore, it is necessary to cancel auto-cruise to protect the engine, and auto-cruise is canceled by detecting an electrical signal from the clutch operation.

FIG. 5 is an explanatory diagram showing an example of a conventional accelerator device with auto cruise, in which a grip plate 2 is connected to an accelerator grip 1, and a carburetor plate 4 is linked to this grip plate 2 via a wire cable 3. be. The carburetor plate 4 opens and closes the throttle valve of the carburetor in conjunction with the carburetor plate 4. Further, this carburetor plate 4 is urged in the throttle valve closing direction by a spring 5, and is linked to an actuator plate 7 via a wire cable 6. It is linked via a wire cable 8 to an actuator 9 of the autocruise device. Therefore, when the auto-cruise operation is not being performed, the carburetor plate 4 is interlocked via the grip plate 2 and the wire cable 3 in response to the amount of operation of the accelerator grip 1 to open and close the carburetor. On the other hand, during autocruise, the actuator 9 operates to pull the wire cable 8 by a predetermined amount, so the actuator plate 7
Then, the carburetor plate 4 is rotated via the wire cable 6, and at the same time, the opening degree of the slot valve is adjusted to the set speed. When the accelerator grip 1 is forcibly returned, if the vehicle speed becomes low, a difference occurs between the set vehicle speed and the actual vehicle speed, and a speed increase signal is supplied to the actuator 9, and the operating force of the actuator 9 is used to control the carburetor plate. Since the accelerator grip 1 is attempted to be rotated to the speed increasing side at the same time as the opening degree of the accelerator grip 4 is adjusted, auto-cruise is canceled so that the forced return operation force of the accelerator grip 1 overcomes the operating force of the actuator 9.

Therefore, in such a conventional accelerator device with auto-cruise, when canceling auto-cruise by forcibly returning the accelerator grip 1, the forced returning operation of the accelerator grip 1 requires a force that overcomes the operating force of the actuator 9. However, there was a problem in that it was not easy to operate.

(Purpose of the invention) This invention was made by focusing on the above-mentioned problems with the conventional technology. The purpose of the present invention is to provide an accelerator device with auto-cruise that allows for automatic cruise control.
