  • Patent number: 11760342
    Abstract: A driving assist system assists driving of a vehicle. A deceleration target includes at least one of a preceding vehicle, a mandatory stop line, a mandatory stop sign, a traffic signal, and a stop line before the traffic signal that exist ahead of the vehicle. A risk factor includes at least one of a pedestrian, a bicycle, a motorcycle, an oncoming vehicle, and a parked vehicle that exist ahead of the vehicle. The driving assist system executes: deceleration assist control that automatically decelerates the vehicle before the deceleration target; and risk avoidance control that automatically performs at least one of steering and deceleration of the vehicle so as to avoid the risk factor. When both the deceleration assist control and the risk avoidance control operate concurrently, the driving assist system notifies a driver of the vehicle of not the deceleration target but the risk factor.

  • Patent number: 11685439
    Abstract: A driving assistance apparatus includes: an assist device configured to perform a steering assist in which a steering torque for steering a vehicle in a direction away from a pedestrian is applied to the vehicle; and a canceller configured to cancel the steering assist if a cancellation condition is satisfied. The cancellation condition includes: a first condition caused by that at least a part of a traffic lane is not recognized; and a second condition caused by that a vehicle operation by a driver is performed. The canceller applies a steering torque in an opposite direction, which is opposite to a direction of the steering torque applied by the steering assist, to the vehicle if the first condition is satisfied, and is configured to increase a torque change amount per unit time of the steering torque in the opposite direction in comparison with when the second condition is satisfied.

  • Patent number: 11535297
    Abstract: A driving support system that supports driving of a vehicle executes steering support control that steers the vehicle in a first direction away from a risk factor in front of the vehicle. A target steering amount in the steering support control is represented by a function of a relative relationship parameter including a lateral distance between the vehicle and the risk factor. A straight road is a road having a curvature less than a first curvature. A curved road is a road having a curvature equal to or greater than the first curvature. When a road ahead from the vehicle to the risk factor includes the curved road, the driving support system reduces the target steering amount for the same relative relationship parameter or advances a start timing of the steering support control as compared to when the road ahead is the straight road.
