Control device for a hybrid vehicle
First Claim
1. A control device for a hybrid vehicle having a motor drivingly coupled with an engine, and a transmission which transmits an output torque that is output from the engine and the motor to driven wheels, comprising:
- a take-off requirement detection unit that detects a start of movement requirement of a driver; and
a torque control unit that limits torque input to the transmission by generating a negative torque using the motor when the start of movement requirement of the hybrid vehicle is detected by the take-off requirement detection unit.

Abstract
A control unit for a hybrid vehicle includes a take-off detection unit that detects a start of movement of the hybrid vehicle from a stopped state; and a torque control unit that limits a engine torque input to an automatic transmission from becoming excessive by generating negative torque using a regeneration operation of a motor on occasions when the start of running of the hybrid vehicle is detected by the take-off detection unit. Accordingly, it is possible to reliably inhibit problems, such as an occupant of the hybrid vehicle being caused to feel an unpleasant jolt due to torque transmitted to a driven wheel side increasing instantaneously as a result of change in an application state of a clutch during the start of movement.
