Title:
CONTROL DEVICE OF POWER UNIT
Document Type and Number:
Japanese Patent JP2016166647
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a control device of a power unit which does not generate a gear change shock in a multi-stage gear change control mode for gear-changing a gear change ratio to a multistage state, and can impart a further clearer gear change feeling to a driver.SOLUTION: A TCU 40 which constitutes a control device 1 of a power unit comprises: a torque increase/decrease amount initial value acquisition unit 42 which acquires a torque increase/decrease amount initial value on the basis of engine torque at a start of a gear change, a gear change ratio at the start of the gear change, and a target gear change ratio of a multistage gear change; a correction coefficient acquisition unit 43 which acquires a first correction coefficient for correcting the torque increase/decrease amount initial value on the basis of a degree of gear change progress; a torque increase/decrease requirement value acquisition unit 44 which acquires a gear change torque increase/decrease requirement value for cancelling inertial torque which is generated accompanied by a gear change; and a torque upper limit value setting unit 45 which sets a torque upper limit value for limiting the output torque of an engine on the basis of an added value of the torque increase/decrease amount initial value after correction which is corrected by the first correction coefficient, and the gear change torque increase/decrease requirement value.SELECTED DRAWING: Figure 1
