Title:
DRIVE CONTROLLER IN HYBRID VEHICLE
Document Type and Number:
Japanese Patent JP3956536
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent a transitory decrease in driving torque and a feeling of deceleration caused thereby when an engine is put in an idling state and a creep running state is shifted to an accelerated state using an assist motor.
SOLUTION: When an internal combustion engine is put in an idling state and a creep running state assisted with output torque of a motor is detected by a creep running detecting means (step 021), the revolutions of an engine should be increased on the basis of a demand of an increase in driving force in the running state. In this case, a torque command value for controlling the output torque of the motor and increasing the revolution of the engine is so controlled that the torque command value is not smaller than that of the running state under a given reference condition, and then a decrease in demand of driving force can be prevented by the electric motor torque controlling means (step 030).
