Abstract: Even if an adjustable speed limitation function (ASL) sets a vehicle speed upper limit to a relatively low vehicle speed, a control unit 10 is configured to, in order to suppress the problem of a decrease in fuel efficiency while the ASL is executing the vehicle speed limitation, suppress an output of an engine 2 so that the vehicle speed does not exceed the vehicle speed upper limit, and cause a gear stage of an automatic transmission 3 to be shifted up to a higher speed side gear stage having higher fuel efficiency than a gear stage that is set based on the driving state of a vehicle 1, when a deviation between the vehicle speed detected by a vehicle speed sensor 21 and the vehicle speed upper limit that is set by a vehicle speed upper limit setting switch 24 becomes less than a predetermined threshold.

Abstract translation: 即使可调速限制功能（ASL）将车速上限设定为相对较低的车速，控制单元10也被配置为为了在ASL执行车辆时抑制燃料效率降低的问题 抑制发动机2的输出，使得车速不超过车速上限，并且使自动变速器3的齿轮级向上移动到具有较高燃料效率的高速侧齿轮级 基于车辆1的行驶状态设定的齿轮级，当由车速传感器21检测到的车速与由车速上限设定开关24设定的车速上限的偏差变小时 超过预定阈值。
