摘要

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 (α) 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.

主权项

1. A vehicle in which at least one of a front wheel pair and a rear wheel pair thereof is driven, comprising:
a left electric motor connected mechanically to a left vehicle wheel; a right electric motor connected mechanically to a right vehicle wheel; a generator connected mechanically to an internal combustion engine; an electrical storage device connected electrically to the left electric motor, the right electric motor, and the generator; and a motor controller configured to control motive power generated by the left electric motor and the right electric motor; wherein, on a basis of an allowable input/output electric power of the electrical storage device, a generated electric power of the generator, and a left and right total electric power consumed or generated by the left electric motor and the right electric motor together, the motor controller is configured to determine an allowable electric power variation range, which is an allowable variation range for the left and right total electric power, and then based on a value obtained by dividing into equal parts the allowable electric power variation range, the motor controller is configured to separately and independently control the motive power of the left electric motor and the right electric motor.
