A driving assistance device provides driving assistance for avoiding a collision between an own vehicle and an object around the own vehicle, based on detection information on the object. The driving assistance device includes: a primary target determination unit that, based on the detection information, determines an object to be a primary target of which a collision with the own vehicle is to be avoided; a secondary determination region setting unit that, based on the detection information, sets a secondary determination region in which to determine an object to be a secondary target of which a collision with the own vehicle is to be avoided on an avoidance steering route of the own vehicle for avoiding a collision with the primary target; a secondary target determination unit that, based on the detection information, determines an object to be the secondary target in the secondary determination region; and a steering assistance unit that provides steering assistance to the own vehicle. The steering assistance unit suppresses avoidance steering of the own vehicle if the primary target determination unit determines that the primary target exists and the secondary target determination unit determines that the secondary target exists.

Driving assistance device

When a collision avoidance steering control start condition becomes satisfied, a driving support ECU starts a steering control to avoid a collision with a frontward vehicle. The ECU prohibits the steering control when an indicated direction by turn indications of the frontward vehicle is the same as a planned direction of the steering control. The ECU sets the start condition to a first start condition, when the turn indicators of the frontward vehicle are not indicating a turning direction. The ECU sets the start condition to a second start condition, when the indicated direction is different from the planned direction. The first and second start conditions have been set such that an inter-vehicular distance between the host vehicle and the frontward vehicle of when the second start condition can be satisfied is shorter than one of when the first start condition can be satisfied.

Collision avoidance support apparatus

A vehicle collision avoidance assistance device is configured to perform forced braking or forced steering when a driver's vehicle has a possibility of colliding with an object ahead of the driver's vehicle, acquire at least one of information related to a condition of the driver's vehicle and information related to a situation around the driver's vehicle, determine, based on the acquired information, whether a request condition for requesting execution of the forced steering is satisfied and whether a forbiddance condition for forbidding the execution of the forced steering is satisfied, perform the forced braking when the request condition is not satisfied regardless of whether the forbiddance condition is satisfied, perform the forced steering when the forbiddance condition is not satisfied and the request condition is satisfied, and perform the forced braking when the forbiddance condition is satisfied though the request condition is satisfied.

Vehicle collision avoidance assistance device

A vehicle collision avoidance assist apparatus executes a collision avoidance control for avoiding a collision of an own vehicle with an object ahead of the own vehicle. The apparatus determines whether a driver of the own vehicle has a collision self-avoidance probability that the driver can avoid the collision of the own vehicle with the object ahead of the own vehicle by carrying out a driving operation to the own vehicle. When the apparatus determines that the driver does not have the collision self-avoidance probability, the apparatus sets a start timing of starting executing the collision avoidance control to a timing earlier than the start timing set when the apparatus determines that the driver has the collision self-avoidance probability.

Vehicle collision avoidance assist apparatus

A vehicle collision avoidance assist apparatus executes a collision avoidance steering maneuvering assist process of applying a steering force to an own vehicle to assist a collision avoidance steering maneuvering carried out by a driver when there is a probability that the own vehicle collides with an object ahead of the own vehicle, and the driver carries out the collision avoidance steering maneuvering to steer the own vehicle to avoid a collision of the own vehicle with the object. The apparatus notifies the driver of a necessity of carrying out the collision avoidance steering maneuvering when determining that there is the possibility that the own vehicle collides with the object ahead of the own vehicle.

A vehicle control apparatus executes a collision avoiding control of avoiding collision of an own vehicle with an object when a predetermined execution condition becomes satisfied. The collision avoiding control includes a steering control of changing a steering angle of the own vehicle and a braking force control of applying braking force to the own vehicle so as to realize a target deceleration. The vehicle control apparatus terminates the steering control and decreases the target deceleration at a first rate to terminate the braking force control when a predetermined steering termination condition that the collision has been avoided, becomes satisfied. The vehicle control apparatus terminates the steering control and decreases the target deceleration at a second rate to terminate the braking force control when a predetermined cancelation condition that a driver carries out a driving maneuver, becomes satisfied. The second rate is greater than the first rate.

Vehicle control apparatus

A vehicle collision avoidance assist apparatus executes a steering avoidance control of setting an avoidance route for avoiding the collision of the own vehicle with the object in a lane in which the own vehicle moves and executing an avoiding steering process of forcibly steering the own vehicle so as to move the own vehicle along the avoidance route when an index value representing a probability of collision of an own vehicle with an object ahead of the own vehicle becomes equal to or greater than a predetermined index value. The apparatus stops an execution of the steering avoidance control when a departing amount of the own vehicle from the avoidance route becomes equal to or greater than a predetermined departing amount while the electronic control unit executes the steering avoidance control. The predetermined departing amount is set for each of sections of the avoidance route.

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.

A vehicle control apparatus includes an electric control unit that performs a preceding vehicle trailing control which makes an own vehicle trail a preceding vehicle as an adaptive cruise control, and performs a first brake control which automatically applies a first braking control to the own vehicle when a time-to-collision to a target object is less than a first threshold. In a case where a performing condition for the first brake control has been determined to be satisfied during a performance of the adaptive cruise control, the electric control unit continues performing the adaptive cruise control without performing the first brake control when a deceleration control by the adaptive cruise control is being performed, whereas stops performing the adaptive cruise control when the deceleration control by the adaptive cruise control is not being performed.

In a case where a performing condition for the first brake control has been determined to be satisfied during a performance of the adaptive cruise control, the electric control unit continues performing the adaptive cruise control without performing the first brake control when a deceleration control by the adaptive cruise control is being performed, whereas stops performing the adaptive cruise control when the deceleration control by the adaptive cruise control is not being performed.

A brake controller is applied to a vehicle that includes a tractor and a trailer. The brake controller includes a first braking unit that controls a first brake device, a second braking unit that controls a second brake device, a distance sensor that detects a distance between the vehicle and an object, an execution unit that controls the first braking unit and the second braking unit in accordance with the distance detected by the distance sensor and executes an automatic brake control, and a prohibition unit that prohibits the execution unit from executing the automatic brake control. The brake controller prohibits execution of the automatic brake control under the condition that the tractor and the trailer are coupled to each other and the second braking unit includes a failure.
