  • Patent number: 11975717
    Abstract: A vehicle control system includes a detector and a processor. The detector is configured to detect a first stop line on the basis of map data stored in a road map database, and detect a second stop line on the basis of traveling environment data acquired by a camera unit. In a case where the detector detects the first stop line, the processor is configured to control a vehicle to decelerate at a first deceleration rate calculated on the basis of a distance from the vehicle to the first stop line. In a case where the detector detects the second stop line after detecting the first stop line, the processor is configured to control the vehicle to decelerate at a second deceleration rate calculated on the basis of a distance from the vehicle to the second stop line and stop at the second stop line.

  • Publication number: 20230001895
    Abstract: A driving assistance device for a vehicle includes a traveling environment recognizer, a braking force learner, and a braking force complementer. The traveling environment recognizer is configured to recognize traveling environment information related to an outside of the vehicle. The braking force learner is configured to, in a case where a driver who drives the vehicle has started a brake operation against a braking target recognized ahead based on the traveling environment information before a timing set based on a correlation between the vehicle and the braking target, acquire a braking force characteristic learning value based on a braking force generated from start to end of braking performed by the brake operation. The braking force complementer is configured to, in a case where the driver has started the brake operation after the set timing, complement the braking force based on the braking force characteristic learning value.

  • Publication number: 20230001918
    Abstract: A vehicle control system includes a vehicle estimator and a stop position setter. The vehicle estimator is configured to make determination on whether an entering vehicle entering an oncoming lane from an intersecting road is present, and estimate an overall length of the entering vehicle upon determining that the entering vehicle is present. The intersecting road intersects a traveling road where a vehicle to which the vehicle control system is applied is traveling. The stop position setter is configured to set a stop position of the vehicle based on the determination made by the vehicle estimator as to whether the entering vehicle is present and the estimated overall length of the entering vehicle.

  • Patent number: 10151046
    Abstract: Provided is a method that allows growing a single crystal of silicon carbide on an off-substrate of silicon carbide while suppressing surface roughening. The method for producing a crystal of silicon carbide includes rotating a seed crystal of silicon carbide while bringing the seed crystal into contact with a starting material solution containing silicon and carbon. A crystal growth surface of the seed crystal has an off-angle, and the position of a rotation center of the seed crystal lies downstream of the central position of the seed crystal in a step flow direction that is a formation direction of the off-angle.
