    Abstract: A vehicle drive system includes a left-wheel drive unit having a first motor and a first transmission, a right-wheel drive unit having a second motor and a second transmission, and a motor control unit. Each of the first and second transmissions has a first to third rotational elements. The first motor is connected to the first rotational element of the first transmission. The second motor is connected to the first rotational element of the second transmission. The left wheel is connected to the second rotational element of the first transmission. The right wheel is connected to the second rotational element of the second transmission. The third rotational element of the first transmission and the third rotational element of the second transmission are coupled to each other. Each of the first and second transmissions has a fourth rotational element which is supported to revolve around by the second rotational element.

    Abstract: A control system that performs control of an electric motor is described. The control system may include a rotating body inertia torque computing unit that uses a rotational state of a vehicle wheel when braking is applied to the wheel to calculate an inertia torque of rotating bodies residing within a span behind the wheel, among members that rotate by the driving force of the electric motor. The control system also may include a controller that performs control of the electric motor to cancel the inertia torque of the rotating bodies based on the calculation result from the rotating body inertia torque computing unit.

    Abstract: When both a left rear wheel and a right rear wheel are driven by first and second electric motors, and acceleration slippage occurs at either the left wheel or the right wheel, the acceleration slippage is reduced by decreasing the command motor torque (power drive torque) of the first or second electric motor connected to the wheel at which acceleration slippage was generated. The command motor torque of the first or second electric motor connected to the other wheel (wheel on the other side) on the right or left side that is opposite the wheel at which slippage occurred is increased, thereby making it possible to supplement the decrease in the driving torque of the wheel at which slippage occurred.

    Abstract: A vehicle driving system includes a slip detector that detects an occurrence of excess slipping; an additive/subtractive slip point calculator that time-discretely calculates an additive/subtractive slip point, which is an additive slip point or a subtractive slip point, on the basis detection or non-detection of an occurrence of excess slipping; a cumulative slip point calculator that sequentially calculates a cumulative slip point that is a cumulative sum of values of the additive/subtractive slip point; and a driving mode switcher that switches between a two-wheel driving mode and an all-wheel driving mode on the basis of the cumulative slip point. When excess slipping is detected, the additive/subtractive slip point calculator calculates the additive slip point on the basis of a driving force correlation value that correlates to a driving force a driving wheel for which the excess slipping has occurred.

    Abstract: A vehicle in which a drive state can be favorably selected in a configuration that separately and independently drives front and rear wheels and a method for controlling the vehicle. In the vehicle and control method thereof, a drive state control device prohibits operation of a first switch between front wheel drive (FWD) and all wheel drive (AWD) and a second switch between rear wheel drive (RWD) and AWD when a lateral acceleration related value of the vehicle exceeds a first threshold value G1. The first threshold value G1 is set with a divergence reference value Gref as a reference. The Gref value is determined considering factors such as lateral acceleration, turning characteristics and the drive state of the vehicle.
