| 摘要 |
The present invention relates to a controller for running a vehicle at a constant speed, according to which a control gain is increased for a predetermined period of time from a moment when a constant-speed running control is initiated and, then, the control gain is returned to the initial value in response to a speed deviation ( epsilon ). Therefore, there is no probability in which the speed deviation ( epsilon ) greatly increases immediately after the constant-speed running control is begun, that will be caused by the uphill and downhill of the road and a variation in the play for the opening control of a throttle valve (9). In particular, the running speed does not exceed a target speed when running the downhill gradient or the play is small. |
