Vehicle backing support apparatus
First Claim
1. A vehicle backward movement assisting apparatus during parking comprising:
- a camera for picking up the rear view of a vehicle;
a monitor disposed at the driver'"'"'s seat;
a recognizing means for recognizing a start of turn of the vehicle;
a detecting means for detecting a turn angle of the vehicle after the start of turn;
means for indicating an acquisition of a turn angle, said means also indicating a time for detecting the turn angle; and
means for controlling the monitor to display an image from the camera, while the vehicle is moving backward, and to superimposedly display, on the monitor, a guide display based on the detected turn angle, for assisting the vehicle in a backward movement during parking, wherein the means for controlling the monitor guides a steering amount, determined based on a positional relationship between said guide display and a target parking space, obtained as an image from the camera.

Abstract
An object of the present invention is to provide a vehicle backward movement assisting apparatus during parking, in which a steering assisting guide display is performed so that a driver can easily comprehend a steering rate and time frame, a steering amount or a backward movement amount in parking a vehicle. When a vehicle starts a turn, a detecting means of a rotation speed difference between a right wheel and a left wheel detects a rotation speed difference between a right wheel and a left wheel. When the difference becomes the predetermined value or larger, it is recognized that the vehicle starts the turn. The angle speed, which is detected by a yaw rate sensor since the start of the turn, is added as a yaw angle. Then, the vehicle is stopped and a shift lever is operated so as to be set to a backward movement position, whereby the yaw angle at this time is detected as the turn angle since the time of starting the turn. An image processor displays a parallel parking guide line and a vehicle space mark so as to be inclined on the screen of a monitor based on the turn angle.
