Abstract
A vehicular transmission including an engine, a continuously variable transmission CVT and a starting clutch. The driving force from the engine is transmitted through the continuously variable transmission CVT with a speed change to a countershaft, and the starting clutch is used to transmit this driving force from the countershaft to wheels of a vehicle. The continuously variable transmission CVT is hydraulically controlled by a control valve CV which receives control signals through a line from an electrical control unit ECU. After the vehicle has decelerated and stopped, and after the engine has stopped by an idling elimination control, the electrical current that controls the control valve CV is adjusted almost to zero.
Claims8
A stop control system for a power transmission used for driving a vehicle, said transmission comprising an engine and a speed change mechanism which transmits a driving force from said engine with a speed change, said engine being stopped when said vehicle is brought into a halt,
- wherein:
- after said engine is stopped, a control for decreasing an electrical current that controls said speed change mechanism is executed by an ECU, and
- wherein said speed change mechanism comprises a control valve.
