Accelerating controller for vehicles

Abstract

A vehicle acceleration control device in which a monitoring start condition judging unit 80 judges whether or not an engine 1 satisfies a monitoring start condition for judging that a start start control condition is satisfied. The monitoring start condition is determined based on the vehicle speed, throttle opening, and engine speed. Specifically, among the parameters such as vehicle speed, at least the engine rotation speed is set to be equal to or lower than the rotation speed when the starting clutch is engaged. The start control condition judging unit 81 judges whether it is a sudden acceleration or not based on whether it is a magnitude corresponding to the sudden opening of the throttle valve when the monitoring start condition judging unit 80 has judged that the condition is satisfied. The ignition delay unit 82 issues a command to the ignition timing control unit 83 to delay the ignition timing in order to limit the output when sudden opening of the throttle valve is detected. In this way, ride comfort can be improved.

Description

technical field [0001] The present invention relates to an acceleration control device for a vehicle, in particular to an acceleration control device for a vehicle suitable for preventing excessive acceleration operation, that is, sudden acceleration of the vehicle, so as to improve walking stability. Background technique [0002] Two-wheeled motor vehicles that limit sudden acceleration at the start of walking to achieve smooth acceleration are known. For example, in the acceleration control device for a motorcycle described in Japanese Patent Application Laid-Open No. 7-180644, attention is paid to the phenomenon that the bifurcated member (front fork) supporting the front wheel is extended due to a change in the posture of the vehicle during acceleration. Sudden acceleration is detected based on the elongation of the front fork, and the ignition timing is delayed. [0003] In the conventional acceleration control device described above, there are the following problems. ...

AI Technical Summary

Problems solved by technology

First, in order to secure a space for installing the sensor for detecting the elongation of the front fork, the degree of freedom of design around the front fork where the sensor is installed is reduced

Second, the change of the front fork due to the change of the vehicle posture is after a sudden acceleration, so for example, sudden acceleration cannot be avoided to smoothly connect the starting clutch, especially the state of starting the connection of the starting clutch cannot be stabilized to improve riding comfort

Third, the elongation of the front fork varies under the same acceleration due to the difference in the number of passengers and weight. Therefore, it is difficult to accurately set the reference value of the elongation of the front fork for judging sudden acceleration.
