PROBLEM TO BE SOLVED: To enable engine horsepower to be generated with optimal fuel efficiency, by synthesizing the quotient in which the required battery horsepower is divided by the vehicle speed and the target horsepower, and setting both the target engine torque and the target input shaft speed of the automatic transmission based on the synthesized target driving force. SOLUTION: Output signals from sensors 21 through 25 which detect vehicle speed VSP, accelerator pressure APS, engine speed Ne, input shaft speed Ni, and state of charge SOC, respectively, are introduced to a driving force control controller 10, which first calculates the target driving force Fd. Next, the required battery horsepower Wb is calculated using a map based on the state of charge SOC. Then, the quotient from dividing Wb by VSP is calculated as the required driving force Fdm of the motor generator 1, 4, and difference of Wb from Fd is calculated as the required driving force Fde of the engine 2. The target engine speed Ne is then calculated based on the Fde and VSP, after which the corresponding required engine torque the is calculated. |
