  • Patent number: 6929082
    Abstract: In a parking assist apparatus that assists with moving, by automatic steering, a vehicle from an arbitrary stopping position to a target parking position set by the driver, a setting portion (i.e., a parking assist ECU) sets both a path from the stopping position to the target parking position and a steering operation necessary to bring the vehicle along that path. When this path cannot be set with the steering angle in the stopping position set as the initial steering angle, and when the path can be set with another steering angle as the initial steering angle, an instruction portion (i.e., a monitor or a speaker) instructs the driver to turn the steering wheel to this other steering angle.

  • Patent number: 6919822
    Abstract: According to a parking assist device and a method for assisting parking of the invention, when a parking assist is canceled after a start of the parking assist, and the parking assist is restarted, a target parking position (P2B) is reset at a reset position (P1B). In the invention, at this time, the target parking position (P2B) is determined based on a target parking position (P2A) which is set at a parking preparation position (P1A), and the determined target parking position (P2B) is displayed on a screen of a monitor (4) as a default display position of a target parking frame (11) at a reset time.

  • Patent number: 6907333
    Abstract: An automatic steering device applies a steering torque in an automatic steering mode to a steering shaft of a steering mechanism that turns a wheel of a vehicle in accordance with rotation of the steering shaft connected to a steering wheel. The automatic steering device includes a controller that calculates an automatic steering torque value and a target assist torque value, and an actuator that is controlled by the controller so as to apply torque corresponding to a sum of the automatic steering torque value and the target assist torque value to the steering shaft. The controller calculates the target assist torque value by multiplying an assist torque gain by a steering torque applied by an operator of the vehicle from the steering wheel to the steering shaft, and sets the assist torque gain in the automatic steering mode so as to be smaller than an assist torque gain in a non-automatic steering mode.

  • Publication number: 20050027415
    Abstract: A driving assist apparatus and method for a vehicle capable of guiding the vehicle at appropriate vehicle speed in accordance with the path is provided. The alarm vehicle speed for informing a driver of overspeed during driving assist is set lower for a changing steer region than for a fixed steer region. The lower alarm vehicle speed is set before the changing steer region is entered. Therefore, in the changing steer region, the vehicle speed can be sufficiently reduced, so that a set amount of steering can be accomplished. In the fixed steer region, the vehicle speed can be increased so as to reduce the time of travel.

  • Publication number: 20050027414
    Abstract: A driving assist apparatus for a vehicle which calculates a path by an algorithm suitable for real-time path calculation in a vehicle-installed computing device is provided. A basic path that changes the deflection angle of the vehicle to 0 is computed from an initial vehicle position. From the basic path, a target path is computed, for example, by adding straight-line paths to the two opposite ends of the basic path. On the basis of the target path, a driving assist is performed. During the driving assist, a basic path is re-calculated. If it is determined that a similarity-enlarged path obtained through similarity enlargement of the basic path can be used to reach the target position point, a target path is re-set on the basis of the similarity-enlarged path. Then a driving assist is performed on the basis of the re-set target path.

  • Publication number: 20040267423
    Abstract: A vehicle driving assist apparatus for guiding a vehicle to a target position is provided. A basic path that changes the deflection angle &thgr; to 0 is determined, and is subjected to similarity transformation. On the basis of the similarity-transformed path, a path factoring in transition from the initial steering angle is set. Then, a correction is made such that the area in the running distance-curvature graph regarding this path becomes equal to a corresponding area regarding the basic path, thereby setting a corrected path. The corrected path is similarity-transformed, and then is re-corrected in accordance with transition from the initial steering angle. Thus, a final target path is obtained.
