An automatic driving system includes a control device that controls automatic driving of a vehicle, and a storage device that contains external environment information indicating an external environment of the vehicle. A driving transition zone is a zone in which a driver of the vehicle takes over at least a part of driving of the vehicle, from the control device. A termination target velocity is a target velocity of the vehicle at an end point of the driving transition zone. The control device variably sets the termination target velocity, depending on the external environment at the end point or the external environment surrounding the end point. Then, the control device controls the velocity of the vehicle in the driving transition zone, such that the velocity of the vehicle at the end point is the termination target velocity.

A collision avoidance device includes an electronic control unit configured to: determine whether or not an oncoming vehicle enters inside a turning circle of a host vehicle turning; and execute a collision avoidance control in a case where the electronic control unit determines that there is a collision possibility between the host vehicle and the oncoming vehicle, wherein the electronic control unit is configured not to execute the collision avoidance control when the electronic control unit determines that the oncoming vehicle enters inside the turning circle of the host vehicle.

Collision avoidance device

A collision avoidance device includes an electronic control unit configured to: determine whether or not a driver of a host vehicle performs turn-back steering based on a detection value of a steering angle or steering torque detected by a steering sensor of the host vehicle; and execute the collision avoidance control for avoiding a collision between the host vehicle and an obstacle in a case where the electronic control unit determines that there is a collision possibility between the host vehicle and the obstacle based on a path of the host vehicle and a position of the obstacle, wherein the electronic control unit is configured not to execute the collision avoidance control while the electronic control unit determines that the driver of the host vehicle performs turn-back steering.

A collision avoidance device includes an electronic control unit configured to: calculate a deflection angle that is a change angle of a direction of a host vehicle turning in a direction of a blinker in a turn-on state based on a direction of the host vehicle when the host vehicle switches the blinker into the turn-on state; and execute a collision avoidance control for avoiding a collision between the host vehicle and an obstacle in a case where the electronic control unit determines that there is a collision possibility between the host vehicle and the obstacle based on a path of the host vehicle on an intersection and a position of the obstacle, wherein the electronic control unit is configured not to execute the collision avoidance control when the deflection angle is equal to or greater than a deflection angle threshold.

An object of the present invention is to provide an object detection apparatus and a driving assistance apparatus in which movement information of a target object can be obtained with high accuracy. In the present invention, the object detection apparatus is an apparatus that detects a target object from a predetermined mounting position (a vehicle and the like); performs an object detection from a predetermined mounting position; in a case where a target object is detected, acquires the position of the target object; obtains a feature amount of a fixed object existing around the target object and detects a position of a fixed object; sets the position of the fixed object as a reference point; and calculates movement information of the target object from the position of the target object with the reference point as a reference.

In a driving support device for a vehicle including a collision avoidance support system and a lane travel support system, a steering control amount is set while maintaining an appropriate relationship between both of the systems. This is by setting a lower upper limit value for the steering torque command during collision avoidance as compared to lane travel support. However, a gradient (i.e., rate of change) of the collision avoidance is set to be greater than a gradient of the lane travel support. As a result, the driving support device balances collision avoidance and lane travel support to have quick response during collision avoidance, and maintaining the ability to adapt to wide changes in road condition during lane travel support.

An object of the invention is to accurately predict a movement trajectory of an object from a history of positions of the object even in a case where shaking or deflection of a vehicle occurs. In order to achieve the object, in the invention, the position of the object around the vehicle is acquired (S), a ground speed of the object is acquired (S), a slope &#x3b8; of a trajectory prediction vector (relative movement vector) of the object with respect to the vehicle is calculated by using a speed of the vehicle and the ground speed of the object (S), fitting is performed (classification of the recorded positions of the object in the movement trajectory) with respect to the history of the positions of the object with a straight line having the slope &#x3b8; of the trajectory prediction vector (S), and a straight line having the slope &#x3b8; of the position fitting best in the straight line having the slope &#x3b8; (straight line having a plurality of positions included in a group classified through the fitting) is predicted as the movement trajectory of the object (S).

When a host vehicle travels while being decelerated by an intervention of automatic braking, a support ECU calculates a collision prediction speed at a collision prediction position and determines whether or not the collision prediction speed exceeds a collision prediction speed threshold. The support ECU allows an automatic steering for collision avoidance to intervene only in a case where the collision prediction speed is determined to be equal to or less than the collision prediction speed threshold and prohibits the intervention of the automatic steering in a case where the collision prediction speed is determined to exceed the collision prediction speed threshold.

The driving-assistance device in which, when a three-dimensional object is present on a course of a host vehicle, driving assistance for avoiding a collision between the host vehicle and the three-dimensional object is implemented on a condition that an unavoidable three-dimensional object is present in a predetermined range including the course, the driving-assistance device comprises a setting unit configured to set the predetermined range in the vicinity of the host vehicle at a degree of width depending on the three-dimensional object, wherein, when a plurality of the three-dimensional objects are detected within the predetermined range, the setting unit makes the degree of width smaller than when a single three-dimensional object is detected within the predetermined range.

The present invention is intended to provide a technique which is capable of detecting a collision position of a moving object crossing a road and a subject vehicle with a higher degree of accuracy. In the present invention, in cases where the moving object crossing the road into which the subject vehicle has entered is detected at the time when the subject vehicle has turned to the right or to the left, the direction of a moving vector of the moving object is fixed to a direction which is set based on a shape of the road into which the subject vehicle has turned to the right or to the left. Then, the collision position of the moving object and the subject vehicle is predicted based on this moving vector of which the direction is fixed.

An object of the present invention is to further improve the detection accuracy of a lateral position of a target in an object detecting apparatus for detecting an object by using a radar and a monocular image sensor. In the present invention, a target corresponding to a target recognized by the radar is extracted and a right edge and a left edge of the target are acquired from an image picked up by the monocular image sensor. Further, locus approximation lines, which are straight lines or predetermined curved lines for approximating loci of the right edge and the left edge, are derived for the both edges. The edge, which has a larger number of edges existing on the locus approximation line, is selected as a true edge of the target from the right edge and the left edge. The lateral position of the target is derived on the basis of the position of the selected edge.
