Abstract
In a hybrid vehicle wherein an engine (2) and a motor/generator (1) are connected in a state wherein they can be driven mutually, and the engine (2) is connected to drive wheels (8) via a motor (4) via a clutch (3), the output torque of the engine is precisely controlled. A control device to perform this control comprises a mechanism (39, 40) which increases and decreases the output torque of the engine (2), a sensor (11) which detects the output of the motor/generator (1), and a microprocessor (16) programmed to control the output torque increase and decrease mechanism (39, 40) so that the output of the motor/generator (1) is zero when the engine is in the idle running state and the clutch (3) is released.
