Title:
CONTROLLER FOR RUNNING A VEHICLE AT A CONSTANT SPEED
Document Type and Number:
WIPO Patent Application WO/1990/007439
Kind Code:
A1
Abstract:
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.
