Abstract

Abstract A steer angle adjusting apparatus for a vehicle is arranged such that the respective steer angles of right and left steered wheels of the vehicle which are steered by a steering device are adjusted independently of each other by a steer angle adjusting mechanism. A running condition of the vehicle is detected by running condition detectors, and the steer angle adjusting mechanism is controlled by a controller in accordance with the detected running condition. Accordingly, the steering stability is improved irrespective of the running condition of the vehicle.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 85 words
A steer angle adjusting apparatus for a vehicle adapted for adjusting the steer angles of right and left steered wheels of the vehicle which are given steer angles by steering means, characterized be comprising: steer angle adjusting means capable of adjusting the respective steer angles of said right and left steered wheels independently of each other; running condition detecting means for detecting a running condition of the vehicle; and control means for controlling said steer angle adjusting means in accordance with the detected running condition.
Claim 2
Dependent Claim 85 words
A steer angle adjusting apparatus for a vehicle adapted for adjusting the steer angles of right and left steered wheels of the vehicle which are given steer angles by steering means, characterized be comprising: steer angle adjusting means capable of adjusting the respective steer angles of said right and left steered wheels independently of each other; running condition detecting means for detecting a running condition of the vehicle; and control means for controlling said steer angle adjusting means in accordance with the detected running condition.
Claim 3
Dependent Claim 47 words
A steer angle adjusting apparatus according to Claim 1, wherein said control means controls said steer angle adjusting means in accordance with the detected running condition of the vehicle so that the difference between the respective slip angles of said right and left steered wheels is minimized.
Claim 4
Dependent Claim 56 words
A steer angle adjusting apparatus according to Claim 2, wherein said control means controls said steer angle adjusting means so that the sum of the respective steer angles of said right and left steered wheels before adjustment is equal to the sum of the steer angles of said right and left steered wheels after the adjustment.
Claim 5
Dependent Claim 41 words
A steer angle adjusting apparatus according to Claim 3, wherein said running condition detecting means includes a vehicle speed sensor for detecting a vehicle speed and a steer angle sensor for detecting a steer angle of each of said steered wheels.
Claim 6
Dependent Claim 51 words
A steer angle adjusting apparatus according to Claim 4, wherein said steer angle sensor includes a steering wheel rotational angle sensor, lower arm rotational angle detecting means, and steer angle adjustment quantity detecting means for detecting a quantity by which a steer angle is adjusted by said steer angle adjusting means.
Claim 7
Dependent Claim 57 words
A steer angle adjusting apparatus according to Claim 5, wherein said steer angle adjusting means is adapted to cause at least one support point of a lower arm supported by the vehicle body at two points spaced apart from each other in the longitudinal direction of the vehicle to move in the substantially lateral direction of-the vehicle.
Claim 8
Dependent Claim 44 words
A steer angle adjusting apparatus according to Claim 1, wherein said control means controls said steer angle adjusting means in correspondence with a change in the running condition during turning of the vehicle so that the change in attitude of the vehicle is minimized.
Claim 9
Dependent Claim 49 words
A steer angle adjusting apparatus according to Claim 7, wherein said running condition detecting means includes braking/driving force detcting means for detecting braking and driving forces generated in the vehicle, steer angle detecting means, and side slip angle detecting means for detecting a side slip angle of the vehicle.
