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.

Vehicle backing support apparatus

In a vehicle backward movement assisting apparatus for in-line parking, at a stop position of a vehicle, a seesaw switch is manipulated until an in-line guide line is superimposed on a target point which is a corner of a frame of a parking space, and a steering wheel is turned until the vehicle space mark is superimposed on the parking space, and the vehicle is moved backward while the steering angle of the steering wheel is held. When an eye mark is superimposed on the parking space, the vehicle is stopped, and the steering angle of the steering wheel is made maximum and the vehicle is moved backward, to thereby complete the in-line parking at the parking space.

Vehicle backward movement assisting apparatus for in-line parking

A steering assist apparatus includes a camera for picking up the rear side of a vehicle, a monitor disposed in a driver's compartment of the vehicle, a steering angle sensor for detecting a steering angle of a steering wheel, and a display controlling unit for displaying on the monitor an image through said camera when the vehicle reverses and for superimposing and displaying on said monitor a guide display for assisting the drive of the vehicle when the vehicle is to be parked. The guide display includes a steering start guide line fixedly displayed in a predetermined position of an image field of the monitor for guiding a steering start position for parking, and a steering amount guide mark moved and displayed along the steering start guide line on the image field of the monitor in correspondence with a steering angle of the steering wheel detected by the steering angle sensor. The driver performs the steering operation of the vehicle while recognizing the position for the opposite turning of the steering wheel and the steering amount and the steering start position for parking on the basis of the image on the rear side of the vehicle and the steering amount guide mark and the steering start guide line.
