  • Patent number: 11247668
    Abstract: The present invention makes it possible to appropriately grasp a stop cause when a vehicle stops. An ECU 5, which controls a vehicle including wheels and a vehicle body connected to the wheels includes: a wheel stop detection unit 138 that detects a stop of the wheels; a vehicle body stop detection unit 133 that detects a stop of the vehicle body; and a stop cause determination unit 141 that determines a stop cause of the vehicle based on a stop timing of the wheels detected by the wheel stop detection unit 138 and a stop timing of the vehicle body detected by the vehicle body stop detection unit 133. The stop cause determination unit 141 may determine that the stop cause is contact of the vehicle body with an obstacle when the stop timing of the vehicle body is earlier than the stop timing of the wheels.

  • Publication number: 20210245734
    Abstract: Provided is an activation method for a control application, which is more safe, reliable, and comfortable. By collating recorded peripheral information with a currently acquired peripheral environment, it is determined whether remote automatic parking is possible, and a remote control application executed by a mobile communication device is activated.

  • Patent number: 10449969
    Abstract: Provided are a parking path calculation device, a parking assist device, and a parking path calculation method, which are capable of improving a degree of freedom of calculating a parking path. A parking path calculator calculates a virtual parking position establishing a predetermined positional relationship with a parking end position when an own vehicle moves backward from an own vehicle position to a parking end position at a minimum turning radius, and calculates, depending on a positional relationship between the virtual parking position and the parking end position, a parking path on which steered wheels are to be steered to cross a neutral position thereof at a time of guiding the own vehicle.

  • Patent number: 10438487
    Abstract: Provided is a parking assistance device that calculates evaluation results based on a driver's evaluation criterion with regard to a plurality of parking spaces. The parking assistance device includes a parking space recognizer configured to recognize a plurality of parking spaces; a parking space selection criterion setter configured to set a driver's parking space selection criterion; and a parking space candidate calculator configured to calculate a parking space candidate based on the parking space selection criterion.
