Abstract: A driver assist ECU executes a collision avoidance assist operation for avoiding a collision between a host vehicle and an object when a collision determination condition that is satisfied when the host vehicle is predicted to collide with the object is satisfied. The driver assist ECU recognizes a speed limit applied on a lane on which the host vehicle is traveling, and when a current speed limit that is newly recognized at a current point in time is lower than a past speed limit that had been recognized until immediately before the current point in time, changes the collision determination condition to a condition that is easily satisfied, in order for the collision avoidance assist operation to be performed at an earlier timing than when the current speed limit is not lower than the past speed limit.

Abstract: A vehicle control device configured to be capable of executing brake assist control of an host vehicle, wherein a first brake operation tendency including a brake response tendency and a brake operation amount inclination as brake operation characteristics of the driver and a second brake operation tendency for determining a deceleration intention of the driver with respect to the target object are acquired, and when it is determined that the driver is a driver having a low capability level for avoiding a collision risk based on the first brake operation tendency and it is determined that the brake operation is performed with a deceleration intention with respect to the target object based on the second brake operation tendency, the operation of the brake assist control is facilitated.

Abstract: The vehicle control device perceives an object when an object located in front of the host vehicle satisfies a predetermined perception condition, and performs either or both of the following operations: giving a warning to notify an occupant of the host vehicle of a risk of collision with the perceived object, and performing vehicle control for controlling a traveling state of the host vehicle to reduce a risk of collision when a relationship between the host vehicle and the perceived object satisfies a predetermined collision condition. The vehicle control device makes the perception condition easier to be satisfied than the case where the specific condition is not satisfied, when the specific condition including at least the condition that the restricted section in which traffic is restricted exists in front of the host vehicle in the adjacent lane adjacent to the own lane in which the host vehicle travels is satisfied.

Abstract: A vehicle control device comprising an obstacle detection device that detects an obstacle in front of an own vehicle, a following vehicle detection device that detects a following vehicle behind the own vehicle, a notification device that notifies a driver that there is a risk of collision when it is determined that there is a risk that the own vehicle will collide with the obstacle detected by the obstacle detection device, and an information device that informs the driver, when it is determined that the following vehicle detected by the following vehicle detection device is approaching the own vehicle, that the following vehicle is approaching the own vehicle, and the notification device is configured to advance a timing of notifying the driver that there is the risk of the collision.
