Claims

[Claims for Utility Model Registration] Cases in which a gear transmission mechanism with a plurality of selectable gear ratios is interposed between the engine side and the driving wheel side, and torque flows backward from the driving wheel side to the engine side. , the engine side is rotationally driven as a load by this torque, and includes a power transmission mechanism that exerts a braking force to brake the vehicle, and the gear ratio is automatically selected based on a signal from a detection means that detects at least the vehicle speed. In an automatic transmission device that is operated by a driver, an input means is operated by a driver and inputs the degree of the driver's intention to brake, and a driving means is used to detect that the vehicle is in a deceleration driving state other than acceleration or constant speed driving. The state detection means and the magnitude of the braking force when the engine side is driven as a load,
A braking gear ratio map in which the plurality of gear ratios are mapped in advance so as to correspond to the degree of braking intention and vehicle speed, and a signal from the input means and the vehicle speed detecting means when the vehicle is in a deceleration running state. a determining means that refers to a braking speed ratio map and determines a speed ratio that will exert a braking force corresponding to the degree of braking intention and vehicle speed; An automatic transmission device comprising: selection means for selecting a gear ratio of a transmission mechanism.
