  • Publication number: 20190271980
    Abstract: A vehicle control device is equipped with a state control unit adapted to perform a state transition control in which there are combined plural types of travel states in accordance with a travel control mode, and plural types of assist states in accordance with a driving assist mode. Under a sports mode (second travel state) in which a preference of the driver for manual driving is strong, as compared with a normal travel mode (first travel state), the state control unit suppresses a transition from a manual driving state (first assist state) to a normal automated driving state (second assist state) in which a level of driving assistance is high.

  • Patent number: 10179507
    Abstract: Provided is a vehicle in which overdischarge of a battery is protected and turning drivability of the vehicle is improved when there is even a little remaining capacity. An ECU controls the left motive force and the right motive force of the left electric motor and the right electric motor so as not to exceed a differential torque upper limit value, which is the maximum value of the difference between the left motive force and the right motive force established on the basis of the temperature or discharge limit power of the battery. When the battery is at a low temperature or the like and the discharge power is limited, the difference between the left motive force and the right motive force is controlled on the basis of the discharge limit power, whereby the turnability of the vehicle is improved while preventing the risk of damage to the battery.

  • Patent number: 9670856
    Abstract: When a stop position of a piston resulting from the automatic stop is in a range that is on an advance side of a threshold in terms of crank angle, fuel injection is performed at beginning of the automatic restart-up in the cylinder that is in the intake stroke and an ignition is performed in a subsequent initial compression stroke in the same cylinder. When the stop position of the piston resulting is in a range that is on a retard side of the threshold in terms of crank angle, initial fuel injection is performed in the cylinder that next enters an intake stroke among the cylinders of the internal combustion engine after the beginning of automatic restart-up and initial ignition is performed in a subsequent compression stroke in the same cylinder. The threshold is determined in accordance with an amount of deviation of a crank angle.
