Safety running system for vehicle

In a safety running system, a transverse travelling distance resulting when a subject vehicle travels to a current position of an oncoming vehicle is calculated based on the vehicle velocity and yaw rate of the subject vehicle, a relative transverse distance of the oncoming vehicle relative to a vehicle body axis of the subject vehicle is calculated based on a relative distance, relative velocity and relative angle between the subject vehicle and the oncoming vehicle detected by a radar information processor. When a relative transverse deviation obtained by subtracting the transverse travelling distance from the relative transverse distance resides within a range and that state continues to exist over a predetermined time period, it is judged that there is a collision possibility of the subject vehicle with the oncoming vehicle, and automatic steering is performed so as to avoid a collision.

Driving control device for vehicle

In the event that the differential value of the target node deviation is equal to or greater than a deviation threshold, and the absolute value of the steering torque is equal to or greater than a steering torque threshold, the system outputs signals to a brake control device such that deceleration of the vehicle is made with a predetermined deceleration, and outputs signals to an electric power steering control device so as to cancel automatic steering, whereby the system enters a normal power steering mode, and the automatic driving mode is canceled. Thus, abnormal situations are precisely detected during automatic driving, giving consideration to the control error and the intent of the user, thereby enabling driving control matching the intent of the user.

Automatic steering control apparatus for vehicle

An automatic steering control performs an automatic parking control which automatically steers steerable wheels of a vehicle, without requiring a driver to perform steering wheel operation, such that the actual steering angle of the steerable wheels follows a changing target steering angle, whereby the vehicle is moved to a target parking state. When the actual steering angle fails to follow the target steering angle because of insufficiency of the steering drive force of a steering actuator, a braking force difference imparting control is performed so as to apply a predetermined braking force on the steerable wheel located inside a target vehicle locus. As a result, a steering moment is generated in the steerable wheels. This steering moment serves as a force for compensating for the insufficiency of the steering drive force of the steering actuator. As a result, the actual steering angle accurately follows the target steering angle.

Vehicle automatic steering control apparatus

A vehicle control apparatus that for automatic steering control that reduces occupant discomfort and stress is provided. A lane width of a subject lane and a current in-lane ratio are detected. If an off-lane obstacle which may place stress on the occupant is present within a prescribed area, a relative position between each off-lane obstacle and the vehicle is determined. A target in-lane ratio is determined based on the relative position. Specifically, when the off-lane obstacles are present on both the left and right sides of the subject lane, the target in-lane ratio is such that lateral distances to both off-lane obstacles are equal. When the off-lane obstacle is present on only one of either the left or right of the subject lane, the target in-lane ratio is set such that a lateral position away from the off-lane obstacle by a lateral distance set in advance is the target lateral position.
