Title:
VEHICLE CONTROL DEVICE AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2014/175182
Kind Code:
A1
Abstract:
In order to suppress the problem of a decrease in fuel economy during a vehicle speed limit period even when an upper limit vehicle speed is set to a relatively low vehicle speed by a vehicle speed limit function (ASL), a control unit (10), when a difference between a vehicle speed sensed by a vehicle speed sensor (21) and an upper limit vehicle speed set by an upper limit vehicle speed setting switch (24) is less than a predetermined threshold value, suppresses the output of an engine (2) so that the vehicle speed does not exceed the upper limit vehicle speed, while upshifting the gear stage of an automatic transmission (3) toward a high speed side gear stage where better fuel economy can be obtained than a gear stage set on the basis of the drive state of a vehicle (1).
