Parking assist device

A guiding device is disclosed for guiding a vehicle to a target position by controlling the steering angle while estimating the vehicle position at least based on a steering angle value, characterized in that, in estimating the vehicle position, a slowing operation with respect to a change dp in a moving distance of the vehicle is applied to a turning curvature g(Str(p)) estimated based on the steering angle value in order to compensate for the delay due to tire deformation, whereby the delay-compensated turning curvature y(p) is obtained.

Guiding device for guiding vehicle to target place controlling the steering angle

A parking assist apparatus performs a guidance of a vehicle toward a target parking position, even after the guidance has been canceled. The target parking position is set in accordance with an operation applied to a target parking position designation display that is displayed on a screen showing a periphery of the vehicle. It is determined whether a cancellation condition of canceling the guidance of the vehicle toward the target parking position is established. A memory continuously holds target parking position information even after the cancellation condition is established.

Parking assist apparatus

A driving assist apparatus for a vehicle that guides the vehicle to a target position is provided. On the basis of the present direction of the vehicle and the direction of the vehicle at the target position, a basic path that changes the vehicle direction so as to coincide with the target direction of the vehicle at the target position is computed. A path from the present position to the target position is computed by adding a straight-line path to the basic path under a predetermined condition.

Driving assist apparatus and method for vehicle

A vehicle backward movement assist device includes an image capturing means for capturing an image of an outside area in back of a vehicle, a parking mode judging means for judging whether a parking mode by reversing of the vehicle is a back-in parking or a parallel parking, a target parking position inputting means for setting a target parking position where the vehicle is parked based on the parking mode determined by the parking mode judging means, and a displaying means for displaying the image captured by the image capturing means and superimposedly displaying the target parking position set by the target parking position inputting means on the captured image so as to guide the vehicle to the target parking position.

A vehicle driving assist apparatus for guiding a vehicle to a target position is provided. A basic path that changes the deflection angle &#x3b8; 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.

A method for performing a parking assist control for automatically guiding a vehicle to a target parking position includes the steps of calculating a change of a vehicle direction based on a traveling distance of the vehicle and a steering angle obtained by a steering angle sensor, calculating the change of the vehicle direction based on a yaw rate obtained by a yaw rate sensor, and determining whether or not the parking assist control is required to be stopped based on a result of a comparison between the calculated changes of the vehicle direction.

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.

A parking-assist device for an automotive vehicle comprises an imaging unit which creates an image of an exterior behind the vehicle. A target-parking-position input unit inputs a target parking position to park the vehicle when requested. A target-parking-position memory access unit stores the target parking position and reads the stored target parking position when requested. A vehicle-travel-amount detection unit detects an amount of travel of the vehicle. A parking-route determining unit calculates a parking route from a current position of the vehicle to the target parking position. A display unit displays the created image and displays one of the target parking position inputted and the stored target parking position read on the created image in a superimposed manner.

Parking-assist device and reversing-assist device

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.

A parking assist apparatus includes an initial traveling locus calculator for calculating an initial traveling locus, a new traveling locus calculating a new traveling locus when a deviation amount of the present vehicle position from a current traveling locus is equal to or greater than a first predetermined value, and a parking assist for performing a parking assist to guide the vehicle along the traveling locus. The parking assist apparatus further includes an initial traveling locus deviation calculator for calculating the deviation amount of the present vehicle position from the initial traveling locus generated by the calculation of the initial traveling locus calculator. The parking assist stops performing the parking assist when the deviation amount calculated by the initial traveling locus deviation calculator is equal to or greater than a second predetermined value which is smaller than the fist predetermined value.

A parking assist apparatus allows a target parking position to be set by a user moving a target parking frame displayed together with an actual image of surroundings of a vehicle, and automatically guides the vehicle to the set target parking position. In the parking assist apparatus, the target parking frame is initially displayed through the use of past setting of the target parking position by the user.

A parking assist device includes a leading path generation judging device for judging whether an effective leading path to a target parking position is generated. According to the parking assist device, a parking assist for leading a vehicle to the target parking position is conducted in accordance with a judged result of the leading path generation judging device. The leading path generation judging device includes a first judging device for judging whether the leading path is generated when an initial steering angle of the vehicle is determined as a steering angle initial value, and a second judging device for judging whether the leading path is generated when a steering angle other than the initial steering angle is determined as the steering angle initial value in case it is judged that the leading path is not generated by the first judging device.
