装置。 a clutch actuator that connects and disconnects a clutch in a power transmission system of a vehicle; a first clutch stroke sensor that outputs stroke information on a power piston side that forms the clutch actuator;
A second device that outputs stroke information on the release lever side driven by the clutch actuator.
A clutch stroke sensor, a gear position sensor that outputs gear position information of the transmission, a load sensor that outputs load information based on the accelerator opening, and a vehicle speed sensor that outputs rotation information on the clutch output shaft side.
The vehicle is equipped with a gear position information generating means for outputting gear position information, and a clutch braking means for controlling the clutch intermittently when each of the above information is input and a start command is received at a predetermined gear position at a predetermined vehicle speed or less. In the clutch control device for an automatic transmission system, when the release lever side stroke information exceeds the power piston side stroke information, the clutch control means performs clutch engagement control based on the release lever side stroke information. A clutch control device for an automatic transmission system.
