  • Patent number: 6317692
    Abstract: 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.

  • Patent number: 6269307
    Abstract: A lateral deviation &dgr;d which is a lateral distance between an intrinsic appropriate course R for a vehicle Ai and a contact position P at which the vehicle Ai will come into contact with an on-coming vehicle Ao, is calculated based on a relative angle &thgr;, a relative distance L and a relative speed Vs which are detected by a radar device, and based on a vehicle speed Vi of the vehicle Ai detected by vehicle speed sensors. When the lateral deviation &dgr;d is in a range of &dgr;dn<&dgr;d<&dgr;dx, it is determined that there is the possibility that the vehicle Ai will collide frontally with the on-coming vehicle Ao. The lateral deviation &dgr;d can be calculated based on the relative angle &thgr;, the relative distance L and the relative speed Vs provided in one cycle of transmission and reception of beam by the radar device.

  • Patent number: 6256584
    Abstract: A relative lateral deviation calculating device calculates a relative lateral deviation between a vehicle and an on-coming vehicle, based on the state of the on-coming vehicle detected by an object detecting device and a future locus of movement for the vehicle estimated by a movement locus estimating device. When the relative lateral deviation is in a predetermined range, a contact-possibility determining device determines that there is a possibility that the vehicle will come into contact with the on-coming vehicle. Even when the relative lateral deviation is not in the predetermined range, if a steering-state detecting device has detected an involuntary steering operation by a driver, a contact avoiding device increases the steering reaction force of the steering wheel to inhibit the steering operation by the driver in a direction for the vehicle to approach the on-coming vehicle.

  • Publication number: 20010003810
    Abstract: A collision avoiding system is provided to enhance a collision avoiding effect by stabilizing a vehicle behavior during automatic braking. Steering controlling apparatus includes not only an ordinary electric power steering control unit but also an active steering reaction calculating unit for driving a motor of a steering system to compensate for the influence of disturbances, if the vehicle is shocked by an unusual bounce from an uneven road or the like. When obstacle detecting apparatus such as a laser-radar detects an obstacle which requires operation of automatic braking, a control parameter changing unit receives the automatic braking activating signal to make a change in the control parameters for an active steering reaction control.

  • Patent number: 6148943
    Abstract: A system for controlling behavior of a vehicle having a laser radar for detecting an obstacle present on a road on which the vehicle is traveling and operating the brake automatically to avoid contact with the obstacle, and having a power-assist steering actuator including an electric motor installed in the steering system. In the system, it is determined whether the vehicle is steered by the steering wheel as manipulated by the vehicle operator or the vehicle is steered by a force generated by the interplay between the tire and road due to the automatic braking and, when vehicle is steered by the force generated by the tire/road interplay, the electric motor of the steering actuator is controlled to drive in the direction to cancel the force, thereby preventing the vehicle behavior from degrading to deviate from the desired course of travel and preventing various disadvantages such as failure to achieve the desired obstacle detection necessary for an effective obstacle avoidance control.
