  • Patent number: 11912157
    Abstract: In a driving control device that controls a driving system for a vehicle, a voltage monitoring unit determines an abnormality in voltage detection and a current monitoring unit determines that power is supplied to the battery when a battery has a current value on a charge side relative to a predetermined value. When the voltage monitoring unit determines that the voltage detection is abnormal, a running control unit controls a rotating electric machine in such a manner that the vehicle is brought in a fail-safe running state. A power supply control unit controls a power supply source to be in a power supply prohibition state. A switch control unit cuts off a switch, in a case where it is determined that power is supplied to the battery during the power supply prohibition state of the power supply source.

  • Patent number: 11827221
    Abstract: A vehicle including a vehicle control device is disclosed. The vehicle control device determines whether an object is a preceding vehicle and whether a brake light of the preceding vehicle is on or off. When the object is a preceding vehicle and its brake light is on, the vehicle control device transmits a braking request that instructs a braking control device to stop the vehicle at a position at which an inter-vehicle distance between the preceding vehicle and the vehicle is equal to or larger than a first distance. When the object is a preceding vehicle and its brake light is off, the vehicle control device transmits a braking request that instructs the braking control device to stop the vehicle at a position at which the inter-vehicle distance is equal to or larger than a second distance being smaller than the first distance.

  • Publication number: 20230052064
    Abstract: A vehicle sets a first determination region of a first obstacle and a second determination region, on the basis of a position of the first obstacle. The second determination region is located at a position farther than the first determination region. A reliability of the second obstacle is set to a first reliability in a case where a position of a second obstacle falls outside the first determination region and falls outside the second determination region. The reliability of the second obstacle is set to a second reliability higher than the first reliability in a case where the position of the second obstacle falls within the first determination region or falls within the second determination region. Braking is applied to the vehicle body and/or acceleration of the vehicle body is suppressed, on the basis of the reliability of the second obstacle and the position of the second obstacle.
