Abstract
Official abstract text for this publication.
This clutch control apparatus includes: a clutch device that connects and disconnects a power transmission between an engine and a drive wheel; a clutch actuator that drives the clutch device and changes a clutch capacity; a driven mechanism that is arranged between the clutch actuator and the clutch device, is operated by a drive of the clutch actuator, and operates the clutch device; a control part that calculates a control target value of the clutch capacity; and a temperature sensor that measures a temperature of the driven mechanism, wherein the control part corrects the control target value based on the temperature measured by the temperature sensor.
First claim
Opening claim text (preview).
What is claim is: 1. A clutch control apparatus, comprising: a clutch device that connects and disconnects a power transmission between an engine and a drive wheel; a clutch actuator that drives the clutch device and changes a clutch capacity; a driven mechanism that is arranged between the clutch actuator and the clutch device, is operated by a drive of the clutch actuator, and operates the clutch device; a control part that calculates a control target value of the clutch capacity; a temperature sensor that measures a temperature of the driven mechanism; and a cover member comprising a clutch cover that covers the clutch device, wherein the control part corrects the control target value based on the temperature measured by the temperature sensor, wherein the cover member includes a fixation part having a cylindrical shape to which the driven mechanism is fitted, and the temperature sensor is attached to the fixation part. 2. The clutch control apparatus according to claim 1 , wherein the engine comprises the cover member, wherein the cover member covers an outer part of the engine, and wherein the driven mechanism and the temperature sensor are arranged on the cover member. 3. The clutch control apparatus according to claim 1 , wherein the driven mechanism is a slave cylinder that includes a piston which is driven by a hydraulic pressure. 4. The clutch control apparatus according to claim 1 , wherein a detection part of the temperature sensor is provided to be directed toward the driven mechanism. 5. The clutch control apparatus according to claim 1 , wherein the control part reduces the control target value as the temperature measured by the temperature sensor becomes higher. 6. The clutch control apparatus according to claim 1 , wherein the control target value is a value that corresponds to a point at which a connection of the clutch device starts. 7. A clutch control apparatus, comprising: a clutch device that connects and disconnects a power transmission between an engine and a drive wheel; a clutch actuator that drives the clutch device and changes a clutch capacity; a driven mechanism that is arranged between the clutch actuator and the clutch device, is operated by a drive of the clutch actuator, and operates the clutch device; a control part that calculates a control target value of the clutch capacity; a temperature sensor that measures a temperature of the driven mechanism; and a cover member comprising a clutch cover that covers the clutch device, wherein the control part corrects the control target value based on the temperature measured by the temperature sensor, and wherein a detection part of the temperature sensor is provided to be directed toward the driven mechanism. 8. The clutch control apparatus according to claim 7 , wherein the engine comprises the cover member, wherein the cover member covers an outer part of the engine, and wherein the driven mechanism and the temperature sensor are arranged on the cover member. 9. The clutch control apparatus according to claim 7 , wherein the cover member includes a fixation part having a cylindrical shape to which the driven mechanism is fitted, and the temperature sensor is attached to the fixation part. 10. The clutch control apparatus according to claim 7 , wherein the driven mechanism is a slave cylinder that includes a piston which is driven by a hydraulic pressure. 11. The clutch control apparatus according to claim 7 , wherein the control part reduces the control target value as the temperature measured by the temperature sensor becomes higher. 12. The clutch control apparatus according to claim 7 , wherein the control target value is a value that corresponds to a point at which a connection of the clutch device starts.
