Figure 10. Definition of Vehicle Heading. The steering angle is defined as the angle between the front of the vehicle and the steered wheel direction as shown in Figure 11. The steering system has a maximum (minimum) steering angle of +0.52359878 (-0.52359878) radians or +30 (-30) degree. Figure 11.
Steering ratio is the ratio of the number of degrees turned at the steering wheel vs. the number of degrees the front wheels are deflected. So for example, if the steering wheel is turned 20Â° and the front wheels only turn 1Â°, that gives a steering ratio of 20:1.For most modern cars, the steering ratio is between 12:1 and 20:1. This, coupled with the maximum angle of deflection of the wheels gives the lock-to-lock turns for the steering wheel.his works the other way around too of course. If the lock-to-lock turns and the steering ratio are known, the wheel deflection can be calculated. For example if a car is advertised as having a 16:1 steering ratio and 3 turns lock-to-lock, then the steering wheel can turn 1.5x360Â° (540Â°) each way.
