WARMUP CONTROL DEVICE FOR HYBRID VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a warmup control device for a hybrid vehicle capable of improving warmup ability during engine cold time and suppressing deterioration in fuel efficiency.

SOLUTION: The warmup control device for a hybrid vehicle is equipped with a diesel engine 11, an MMT 12, a motor generator 17 for assisting power generation by engine output or engine output by electric power of a battery 20. The warmup control device is equipped with a warmup determination means for determining the warmup state of the engine 11, and an allocation ratio control means for controlling the allocation ratio of the output of the motor generator 17 and the output of the engine 11 according to a battery charge amount SOC and a driver demand output. The allocation ratio control means is structured to control the allocation ratio so that the output of the motor generator 17 is large and the output of the engine 11 is small until completion of warmup is determined by the engine warmup means.
