Vehicle having gear change control device, and method of controlling gearbox

摘要

The present invention relates to a vehicle having a clutch and a gear box as part of a torque transmission path, and comprising: a clutch actuator for changing a degree of engagement of the clutch; a current torque obtaining section for obtaining torque being currently transmitted from a drive-side member of the clutch to a downstream mechanism in the torque transmission path as current torque, the downstream mechanism including a driven-side member of the clutch; a post-completion torque obtaining section for obtaining torque estimated to be transmitted from the drive-side member to the downstream mechanism after completion of engagement of the clutch as post-completion torque; and a control unit functioning as a gear change control device for disengaging the clutch by actuating the clutch actuator and changing shift gears in response to a gear change command, and then controlling the degree of engagement of the clutch according to a difference between the current torque and the post-completion torque, wherein the control unit receives a next gear change command according to the difference between the current torque and the post-completion torque.
