Abstract
Official abstract text for this publication.
The clutch control system includes a motor in a liquid pressure modulator for engagement/disengagement of a clutch, a clutch control unit for controlling the operation of the motor, vehicle condition detection means which detects at least that an engine is in working and which detects the running speed of the vehicle, and neutral detection means for detecting the neutral state of a transmission. As controlled states of the clutch, there are set a first control state in which the clutch is in a partially engaged state or an engaged state, and a second control state in which the clutch is disengaged. When the engine being working and the vehicle speed being in excess of a predetermined value is detected and the neutral state is detected, in the first control state, transition to the second control state is effected and the clutch is disengaged.
First claim
Opening claim text (preview).
I claim: 1. A clutch control system for a clutch operative to engage and disengage transmission of a rotational driving force from an engine of a vehicle to a transmission, comprising: an actuator which engages and disengages said clutch; a controller which controls operation of said actuator; an engine rotational speed sensor which detects the rotational speed of said engine; a vehicle speed sensor which detects the vehicle speed of said vehicle; and a neutral detection u…
