HYBRID VEHICLE AND ENGINE CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide a hybrid vehicle which reliably cancels engine torque reaction force to be transmitted to tires (driving wheels) at the time of power generation during stop.

SOLUTION: The hybrid vehicle is configured to transmit a driving force of an engine 1 to a generator 3 through a planetary gear mechanism 4. The hybrid vehicle transmits the engine torque reaction force which is the reaction force of the driving force of the power generating torque of the engine 1 transmitted to the tires 8 of the driving wheels through a ring gear shaft 4a of the planetary gear mechanism 4 when the generator 3 is driven by the generating torque that is output by the engine 1. Brake retaining torque for a brake 7 is estimated by detecting the position of a brake pedal stepped by a driver in a hybrid vehicle and the power generating torque of the engine 1 is controlled so that the engine torque reaction force that is transmitted to the tires 8 of the driving wheels is smaller than the estimated brake retaining torque.
