範囲第１項記載のクリープ防止手段。[Claims for Utility Model Registration] (1) A torque converter connected to an engine output shaft; a gear-type transmission mechanism connected to the output shaft of the torque converter and having a plurality of power transmission paths;
A transmission path switching means for selectively switching a power transmission path of the transmission mechanism, a shift lever operated by a driver's operation, and operating the transmission path switching means according to a range set by the operation of the shift lever. In the automatic transmission, the automatic transmission is equipped with a shift control means for switching the power transmission path and changing the speed, an engine operation detection means for detecting the operation of the engine, and an engine operation detection means for detecting whether or not a driver is present in the driver's seat. and neutral detection means for detecting whether or not the power transmission path switched and set by the speed change control means is neutral. When it is detected that the power transmission path is set to a path other than neutral, and the driver detection means detects that the driver is absent from the driver's seat, the transmission torque by the gear type transmission mechanism is changed. A creep prevention device for an automatic transmission, characterized in that the creep prevention device for an automatic transmission is actuated to reduce the torque transmitted from the torque converter to the wheels, thereby preventing creep in the vehicle. (2) Creep according to claim 1 of the utility model, characterized in that the creep prevention means is a means for activating the speed change control means to switch the power transmission path to neutral and reduce the transmission torque. Prevention device. (3) Claims of a utility model characterized in that the creep prevention means is a means for operating the speed change control means to change the gear position determined by the power transmission path to a high speed position, thereby reducing the transmitted torque. Creep prevention means according to item 1.
