A collision avoidance assist apparatus executes an emergency steering control including processes to determine a target steering torque used to change a steering angle to avoid a collision of a vehicle with an obstacle so as not to move the vehicle out of a moving lane when the vehicle has a high probability of colliding with the obstacle, and the moving lane is a straight lane, and applies a steering torque corresponding to the determined target steering torque to a steering mechanism. The collision avoidance assist apparatus stops executing the emergency steering control when determining that the moving lane is a curved lane, based on only one of left and right lane markings at an avoidance side of the obstacle which is the left or the right side of the obstacle which the vehicle passes over while executing the emergency steering control.

Collision avoidance assist apparatus

A vehicle control apparatus determines that a control start condition is satisfied when there is an object in an area of a moving route of the own vehicle and determine that a control forbidding condition is satisfied when there is an oncoming vehicle which satisfies a predetermined moving condition that the oncoming vehicle moves in an oncoming lane next to a moving lane of the own vehicle and approaches the own vehicle. The vehicle control apparatus determines that the control forbidding condition is not satisfied when a forbidding cancelling condition is satisfied, the forbidding cancelling condition being satisfied when a first me elapses since determining that the oncoming vehicle satisfying the predetermined moving condition disappears after determining that the control forbidding condition is satisfied and executes the steering control when the control start condition is satisfied, and the control forbidding condition is not satisfied.

Vehicle control apparatus

A vehicle control apparatus determines that a control start condition is satisfied when there is an object in an area of a route which the own vehicle moves and executes a steering control of steering the own vehicle to increase a yaw angle of the own vehicle with respect to a moving lane of the own vehicle and decrease the yaw angle to avoid a collision of the own vehicle with the object when determining that control start condition is satisfied. The vehicle control apparatus determines that a control termination condition is satisfied when the yaw angle becomes equal to or smaller than a predetermined yaw angle, and a steering angle of the own vehicle becomes equal to or smaller than a predetermined steering angle after starting steering the own vehicle to decrease the yaw angle in executing the steering control.

A collision avoidance assist apparatus calculates a lane marking recognition reliability level and execute an emergency steering control. The emergency steering control includes processes to determine a target steering torque to avoid a collision of a vehicle with an obstacle when determining that the vehicle has a high probability of colliding with the obstacle, a moving lane defined by the left and right lane markings is a straight lane, and the calculated lane marking recognition reliability level is equal to or higher than a first threshold reliability level, and apply a steering torque corresponding to the target steering torque to a steering mechanism. The collision avoidance assist apparatus stops executing the emergency steering control when the lane marking recognition reliability level becomes lower than a second threshold reliability level set to a value lower than the first threshold reliability level.
