Vehicular control device
First Claim
1. A control device for a vehicle, comprising:
- an engine;
a first rotating electric machine coupled to the engine;
a second rotating electric machine coupled to the engine;
a battery;
a capacitor provided electrically in parallel with the battery;
a first calculation unit for calculating an output that the second rotating electric machine is required to provide;
a second calculation unit for calculating an output provided from the battery and the capacitor;
a third calculation unit for calculating an output of the first rotating electric machine by subtracting the output that the second rotating electric machine is required to provide from the output provided from the battery and the capacitor; and
a control unit causing the battery and the capacitor to supply power to increase a number of rotations of the second rotating electric machine and also controlling the first rotating electric machine and the second rotating electric machine to prevent the first rotating electric machine from acting as a load of the engine when the vehicle is accelerated as a driving force of the engine is transmitted to a driving wheel, wherein the control unit controls the first rotating electric machine, as based on the output of the first rotating electric machine, to increase a number of rotations of the engine.

Abstract
An ECU executes a program including the steps of: if an accelerator pedal position P is larger than a predetermined accelerator pedal position, calculating an output that an MG(2) is required to provide; calculating an output that a capacitor and a battery can supply; calculating an output that can be supplied to MG(1), by subtracting the output that the MG(2) is required to provide from the output that the capacitor and the battery can supply; calculating a torque that each MG is instructed to output, as based on the output that can be supplied to MG(1) and the output that an MG(2) is required to provide; and controlling inverters (1) and (2), as based on the torque that each MG is instructed to output, to accelerate the vehicle.
