START CONTROL SYSTEM AND VEHICLE

Document Type and Number:

WIPO Patent Application WO/2012/090569

Kind Code:

A1

Abstract:

The purpose of the present invention is to provide technology for mitigating shock to a driver when clutch engagement is being initiated. A RAM (54) stores a first setting value for controlling a clutch (3) in a start standby state and a second setting value for controlling the clutch (3) in a start preparation position. A clutch control unit controls the clutch (3) in the start standby state on the basis of the first setting value if it is determined that the vehicle has shifted to a start standby period, and controls the clutch (3) in a start preparation state, in which the distance between clutch disks is narrower than in the start standby state, on the basis of the second setting value if it is determined that the vehicle has shifted to a start preparation period. The clutch control unit controls the clutch (3) in a direction in which the distance between the clutch disks becomes narrower than in the start preparation state, and the engine speed is controlled in such a way that the engine speed approaches an engine target speed. In the start preparation state, the clutch (3) is controlled in such a way that shock is not generated.
