<P>PROBLEM TO BE SOLVED: To provide a hybrid vehicle control device capable of finely coping with external disturbance such as a difference in a vehicle state and a difference in travel environment and thereby always properly controlling motor assist to achieve a stable fuel cost reduction effect. <P>SOLUTION: An electric power generation amount by regeneration control of a motor is calculated one by one as a previous-cycle power generation amount for each predetermined cycle, and a ΔSOCF/B amount obtained by performing electric power amount conversion of a difference ΔSOC between a target SOC and an actual SOC of a battery is found. When the actual SOC is smaller than the target SOC, an assist upper limit value is calculated by subtracting the ΔSOCF/B amount from the previous-cycle power generation amount. When the actual SOC is larger than the target SOC, the assist upper limit value is calculated by adding the ΔSOCF/B amount to the previous-cycle power generation amount. An electric power use amount when the motor is subjected to power running control in this time cycle is limited by the assist upper limit value. <P>COPYRIGHT: (C)2013,JPO&INPIT |
