  • Patent number: 6597975
    Abstract: A vehicle co-operative control system is provided which suppresses the torque steer phenomenon by co-operatively controlling a driving force and/or braking force distribution device and an electric power steering device without changing the control device of the electric power steering device for a vehicle having a specification in which the co-operative control is not carried out or with the introduction of only a minimal change. The control device can also be applied to a vehicle having a specification in which the co-operative control is carried out.

  • Patent number: 6574559
    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: 6571176
    Abstract: A steering actuator is prevented from generating excess steering torque that gives an uncomfortable feeling to a driver who is holding a steering wheel when a collision between a vehicle and an oncoming vehicle is avoided by automatic steering by the actuator. When there is a possibility of a collision between the vehicle and an oncoming vehicle, the collision with the oncoming vehicle is avoided by supplying a lateral movement control current having a sinusoidal shape to the actuator of an electric power steering device to move the vehicle laterally. The yaw angle of the vehicle is detected by integrating the yaw rate simultaneously with the start of the lateral movement, and in order to return the vehicle attitude of the vehicle to its original state by converging the yaw angle to 0 in the final stage of the lateral movement, a yaw angle correction control current is superimposed on the lateral movement control current and supplied to the actuator.

  • Patent number: 6338022
    Abstract: The operational burden and uncomfortable feeling given to a driver by automatically restoring the disturbance in the vehicle attitude of a vehicle caused by a collision avoidance control, is reduced when avoiding a collision between the vehicle and an oncoming vehicle by automatic steering. When there is a possibility of a collision between the vehicle and an oncoming vehicle, the collision with the oncoming vehicle is avoided by supplying a lateral movement control current I1 having a sinusoidal shape to the actuator of the electric power steering device, to move the vehicle laterally. The yaw angle of the vehicle is detected by integrating the yaw rate simultaneously with the start of the lateral movement, and in order to return the vehicle attitude of the vehicle to its original state by converging the yaw angle to 0 in the final stage of the lateral movement, a yaw angle correction control current I2 is superimposed on the lateral movement control current I1 and supplied to the actuator.

  • Patent number: 6317693
    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.
