Provided is a vehicle in which an internal combustion engine can be suitably assisted by a rotating electrical machine. The vehicle is provided with an internal combustion engine, a rotating electrical machine, a transmission, a clutch placed between the transmission and the combination of the internal combustion engine and rotating electrical machine, and a motive power control device that controls the motive power of the internal combustion engine and the rotating electrical machine. The motive power control device calculates additional motive power for the rotating electrical machine on the basis of the difference between the motive-power-transmitting capacity of the clutch and the motive power of the internal combustion engine.

Vehicle

A power control device of a vehicle disallows generation of additional power of rotating electrical machines when power of an internal combustion engine is transmitted to a transmission via a clutch and an amount of operation of an accelerator pedal is lower than an operation threshold value. The power control device allows generation of additional power of the rotating electrical machines when power of the internal combustion engine is transmitted to the transmission via the clutch and the amount of operation of an accelerator pedal is higher than the operation threshold value.

Control of internal combustion engine and rotating electrical machine for vehicle

In a vehicle, a first rotating electrical machine, is connected to first wheels via a clutch, and second rotating electrical machines are connected to second wheels or the first wheels without going through the clutch. A power control device allocates electric power to the second rotating electrical machines with higher priority over the first rotating electrical machine when adding additional power to power of an internal combustion engine, thereby generating power of the second rotating electrical machines with higher priority over power of the first rotating electrical machine.

According to this vehicle and control method for the same, an electric motor control device sets a target left power and a target right power, on the basis of the power suppliable by a power supply, power loss dependent on the respective rotation state quantities of a left electric motor and a right electric motor, the target power difference between the left electric motor and the right electric motor, and the target sum of power of the left electric motor and the right electric motor, and controls the left electric motor and the right electric motor using the target left power and the target right power.

Vehicle, and vehicle control method

Provided is a vehicle provided with left and right electric motors electrically connected to a battery and mechanically connected respectively to left and right vehicle wheels, a power generator mechanically connected to an internal combustion engine being electrically connected to the battery, wherein the battery is reliably protected during traction control and at other such times. Two electric motors, specifically first and second electric motors, are temporarily handled integrally to determine a torque down amount (TD), which is the total allowable power variation width (&#x3b1;) of the two electric motors, on the basis of left and right total power (Y), and the respective motive powers of the first and second electric motors are controlled while being limited by values obtained by simply dividing the determined torque down amount (TD) equally, whereby the allowable input/output power (allowable input power (Z)) of the battery is reliably protected.
