Motor assist control device for hybrid vehicles

Abstract

To provide a hybrid vehicle motor assist control device capable of preventing a driver from feeling a torque loss during shift transmission.SOLUTION: A hybrid vehicle motor assist control device comprises: an engine 2; a motor 4; a transmission 3 which transmits rotation of the engine 2 to a drive shaft 11 by shifting gears; a clutch 31 which connects or disconnects power transmission between the engine 2 and the drive shaft 11; and a control section 8 which causes the motor 4 to output assist torque when the transmission 3 shifts the gears with the clutch 31 in an incomplete engagement period so that the maximum torque of the motor 4 output in a clutch release process while the transmission 3 shifts the gears can be maintained in a clutch connection process.SELECTED DRAWING: Figure 1
