Vehicle driving support system, and steering angle detection device
First Claim
1. A vehicle steering angle detector comprising:
- a steering angle sensor for detecting the amount of angular displacement of a steering shaft at an exposed portion of the steering shaft; and
a bracket whose base end is secured to a vehicle body in the vicinity of the exposed portion of the steering shaft by a screw used for fixing a bearing of the steering shaft to the vehicle body, wherein the steering sensor is attached to a front end of the bracket.

Abstract
A camera unit 10 is mounted on a vehicle 3. When an attempt is made to park the vehicle 3 in a parking lot, a predicted path 5a and guidelines 5b are displayed on an information display 4 together with an image. Data to be used for displaying the predicted path 5a and the guidelines 5b are stored beforehand in internal memory of an image processing circuit 19 provided in a parking assist ECU 6 so that the data can be selected in accordance with specifications, such as the type of the vehicle 3. The predicted path 5a is computed on the basis of a steering angle detected by a steering angle sensor provided in an exposed portion of the steering shaft 11. The length or color of the predicted path 5a is changed in accordance with the speed of the vehicle 3. Further, a vehicle driving support system is provided with a back sonar 17, and hence the length or color of the predicted path 5a is also changed in accordance with the result of detection of an obstacle.
