Problems solved by technology

[0005] However, in conventional control, downshifting is not permitted when the engine speed is equal to or higher than a predetermined high speed, so there is a possibility that the driver cannot downshift at the desired timing.

Abstract

A clutch control device includes an engine, a gearbox, a clutch device configured to disconnect and connect power transmission between the engine and the gearbox, a clutch actuator configured to drivethe clutch device and vary a clutch capacity, and an ECU configured to calculate a control target value of the clutch capacity, and the ECU determines whether an engine rotational number after downshifting by the gearbox enters a high rotation region and decreases the clutch capacity after downshifting when it is determined that the engine rotational number after downshifting enters the high rotation region.

Description

[0001] This application claims priority based on Japanese Patent Application No. 2017-254248 for which it applied on December 28, 2017, and uses the content here. technical field [0002] The invention relates to a clutch control device. Background technique [0003] Conventionally, a structure including a clutch device for disconnecting or connecting power transmission between an engine and a transmission is known (for example, refer to JP-A-60-139960). [0004] Japanese Patent Application Laid-Open No. 60-139960 describes a control that permits the execution of a downshift when the engine speed is lower than a predetermined high speed. This prevents over-revolution (ultra-high speed rotation) after a downshift. [0005] However, in the conventional control, the execution of the downshift is not permitted when the engine speed is equal to or higher than a predetermined high speed, and therefore there is a possibility that the driver cannot perform the downshift at the desi...
