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: A vehicle control device (a control unit 100) includes a neutral control unit (100b), a brake hold control unit (100c), and a switching control unit (100d) configured to switch, when a predetermined switching condition is satisfied during execution of brake hold control by the brake hold control unit (100c), application of braking force to at least a drive wheel by execution of the brake hold control to application of the braking force to at least some vehicle wheels by an electric parking brake device. The neutral control unit (100b) stops execution of neutral control upon switching by the switching control unit (100d).

Abstract: A vehicle engine speed display device is provided with an engine speed detection unit which detects an engine speed, an engine speed display unit which displays an engine speed, and a display control unit which controls the engine speed display unit on the basis of the detected engine speed. The display control unit determines whether a phase of a gear shift operation is an inertia phase when gear shift control of an automatic transmission is executed, and sets display responsiveness of a tachometer with respect to the detected engine speed higher than display responsiveness to be set when the phase is not the inertia phase, when the phase of the gear shift operation is determined to be the inertia phase.

Abstract: A control method for an automatic transmission includes a step of canceling the shift performed by a shift operation for performing shifting in the same direction as that of the shifting performed by automatic shift control, when the shift operation is performed before the input revolution speed correlation value of the automatic transmission becomes a predetermined value, after the automatic shift control has been started in a manual shift mode, a step of switching a shift stage display at a timing at which the shift operation that is to be canceled has been performed, and a step of switching the shift stage display at a timing at which the input revolution speed correlation value becomes the predetermined value when a shift operation is not performed within a period of time from when the automatic shift control is started till when the input revolution speed correlation value becomes the predetermined value.
Abstract translation: 一种自动变速器的控制方法包括以下步骤：当在输入转速相关值之前执行换档操作时，通过与通过自动变速控制进行的换档相同的方向进行换档的换档操作而进行的换档 在自动变速控制已经在手动变速模式下开始之后，自动变速器变为预定值，在执行要被取消的换档操作的定时已经执行了换档阶段显示的步骤，以及 在从自动变速控制开始到输入转速相关值开始的时间段内不进行变速操作时，在输入转速相关值变为规定值的定时切换变速级显示的步骤 成为预定值。

Abstract: A control device for a multi-stage automatic transmission-equipped vehicle includes a hydraulic power controller, a combustion controller configured to, if a predetermined combustion stop condition is satisfied when the vehicle is traveling, perform deceleration-period combustion stop control, and limit combustion restart triggered by a reduction in rotational speed of an internal combustion engine, during execution of the deceleration-period combustion stop control, and a motoring controller configured to control the rotational drive of the internal combustion engine by a motor during execution of the deceleration-period combustion stop control so that the rotational speed of the internal combustion engine is maintained at a predetermined rotational speed during a period of time from the time that the rotational speed of the internal combustion engine decreases to the predetermined rotational speed until downshifting to a predetermined gear ratio is completed.
