Title:
HYBRID CAR CONTROL DEVICE
Document Type and Number:
Japanese Patent JPH116449
Kind Code:
A
Abstract:

To transmit no torque ripple of an engine to an axle and to ensure desired responsiveness and precision, control of the number of revolutions of an engine.

A hybrid car comprises an engine 1; a power transmission means 12 containing first and second dynamo-electric machines 2000 and 3000; an inverter device 14 to drive the dynamo-electric machines 2000 and 3000; a capacitor device 15; an engine control device 13 to execute control of fuel injection of the engine 1; and a hybrid control device 16 to command a torque control amount to the engine control device 13 and control drive of the inverter device 14. The hybrid control device 16 regulates a given frequency band based on an engine torque ripple by a hand stop filter regarding the number of revolutions of an engine (the actual number of revolutions), and computes the torque command value of the first dynamoelectric machine 2000 by using the number of revolutions of an engine after the regulation. In this case, drive of the dynamo-electric machines 2000 and 3000 is controlled by number of revolutions information from which an engine torque ripple content is removed.
