  • 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: 20230001919
    Abstract: An object detection device includes first and second detectors each configured to detect an object by transmitting an ultrasonic wave in a moving direction of the moving object and receiving a reflected wave of the ultrasonic wave, a second detector, a memory, and a hardware processor coupled to the memory, and configured to: determine that an obstacle is present in the moving direction of the moving object, based on object detection results by the first and second detectors; determine crossing of the obstacle based on object detection results by the first and second detectors in a state in which it is being determined that the obstacle is present; and cause a driving controller mounted on the moving object, to release driving restriction control of restricting movement of the moving object when determining the crossing, or prohibit the driving controller from releasing the driving restriction control under a predetermined condition.

  • Publication number: 20210190605
    Abstract: A correction amount setting apparatus sets a correction amount for a sound wave sensor that is mounted on a vehicle and that detects an obstacle by transmitting and receiving a sound wave, the correction amount being a correction amount of a sensitivity to a reflection wave or a threshold for determining whether an obstacle is present. The correction amount setting apparatus includes: a correction amount calculator that acquires temperature information from a temperature sensor that detects an outside air temperature around the vehicle and, based on the temperature information, determines the correction amount; and a correction amount setter that determines and sets the correction amount for the sound wave sensor when the vehicle, from start of traveling, after having been accelerated to a speed higher than a reference speed, is decelerated to the reference speed.

  • Patent number: 8855897
    Abstract: An apparatus includes a first switch turned ON in response to depression of a pedal, and OFF in response to depression being released; a second switch that assumes a first state in response to depression of the pedal, and a second state in response to pedal release; and a control unit that determines whether the first switch is in the first state. The control unit starts the engine, if in the first state and if the engine start switch is operated.
