Title:
VEHICLE SPEED CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/002239
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a vehicle speed control device that can reliably reduce a driver's feeling of discomfort. In the present invention, an upper limit speed notifying unit 106 notifies a driver of an upper limit speed (set vehicle speed) set by an upper limit speed setting unit 103 at a timing (immediately) when a speed limit acquiring unit 101 acquires a speed limit established for a road on which a host vehicle is traveling or a timing when the upper limit speed setting unit 103 sets the upper limit speed to be applied to the host vehicle in accordance with the speed limit. Further, a speed control unit 105 applies the upper limit speed (as an update) to the control of a traveling speed of the host vehicle at a timing delayed from the timing at which the upper limit speed notifying unit 106 notified the driver of the upper limit speed (set vehicle speed).
