POWER CONTROL APPARATUS FOR HYBRID VEHICLE

摘要

A power control apparatus for a hybrid vehicle (1), the hybrid vehicle including an internal combustion engine (11), a front motor-generator (12), and a transmission (13) which are connected to front wheels (WF), and a rear motor-generator (14) which is connected to rear wheels (Wr) via a rear differential gear box (DR). A calculated value, which is obained by subtracting a front output power F_POWER and an accessory output power DV_POWER from a battery output power limit B_LimPow is set as an rear output power limit R_LimPow. The smaller of a rear drive command R_PowCmd (which is set dipending on the running state of the vehicle) and a rear output power limit R_LimPow is set as a new rear drive command R_PowCmd. Accordingly, a demanded motor output power can be obtained without increasing the size of the main battery (15).
