Problems solved by technology

[0006] In conclusion, since during the forward movement, no image transmitted from the camera is displayed on the display, the driver cannot choose but intuitively find the stopping position for starting the backward movement
Therefore, simply showing the estimated trajectory on the display during backward motion is not enough as a parking aid
[0007] In addition, only displaying the trajectory poses a problem of lack of user friendliness, since it is unclear in which part of the trajectory and how the trajectory fits into the target parking space

Embodiment Construction

[0020] Hereinafter, embodiments of the present invention will be described based on the drawings.

[0021] Such as figure 1 As shown, a rear view surveillance camera 2 for capturing images of the rear of the vehicle 1 is mounted to a rear portion of the vehicle 1 . The rear bumper 3 of the vehicle 1 is captured within the lower end portion of the visible range of the camera 2 . The liquid crystal color display 4 is arranged close to the driver's seat of the vehicle 1 . When a parking assist operation is performed based on the present invention, an image captured by the camera 2 is displayed on a display 4, which is generally used as a display unit of a navigation system. In addition, a shift lever 5 is provided beside the driver's seat. The front wheels 6 serving as steerable wheels are steered by operating the steering wheel 7 .

[0022] figure 2 The structure of the parking assist apparatus according to the first embodiment of the present invention is shown. A control...

Abstract

In the parking assist apparatus disclosed here, when the side parking mode switch is set at the initial stop position A, the controller calculates the backward movement start position B for parking based on the yaw angle and the steering angle of the vehicle, and upon determining the vehicle Guidance information is issued to stop the vehicle when the calculated backward movement start position B has been reached. After having sensed that the shift lever is shifted to the reverse position, the controller displays on the display an image captured by the camera about the area behind the vehicle, and the vehicle moves backward while maintaining the steering angle at the shift lever shift Next, the estimated vehicle space is also shown in an overlay on this display. The driver operates the steering wheel to establish an appropriate positional relationship between the estimated vehicle space and the target parking space on the display, thereby obtaining an appropriate steering angle in the backward moving vehicle.

Description

technical field [0001] The present invention relates to a parking assist device, and more particularly, to a device that provides driving operation guidance to a driver in side parking. Background technique [0002] Conventionally, it has been developed by displaying on a display an image captured by a surveillance camera mounted on a vehicle during a backward motion of the vehicle during a driving operation, and also displaying a corresponding steering wheel superimposed on the displayed image on the display. A driving assistance device that provides assistance by estimating the trajectory of the steering angle, as disclosed in, for example, JP-2002-251632A. [0003] The driving assistance apparatus described above allows the driver to perform, for example, sideways parking the vehicle inside the parking space by driving the vehicle while viewing the estimated trajectory on the display. [0004] The problem to be solved by the present invention [0005] However, despite a...
