Steering angle refers to the angular displacement of a vehicle's front wheels from their straight-ahead position. It is the measurement of the angle formed between the orientation of the front wheels and the longitudinal axis of the vehicle.

Key points about steering angle:

  1. Straight-Ahead Position: When the vehicle is moving in a straight line, the front wheels are in their straight-ahead position, and the steering angle is zero.

  2. Positive and Negative Steering Angle: The steering angle becomes positive when the wheels are turned to the right and negative when turned to the left. The maximum positive and negative angles depend on the design of the vehicle and the steering system.

  3. Importance in Steering Systems: Steering angle is a critical parameter in understanding and controlling the vehicle's direction. It plays a significant role in various safety and stability systems, such as electronic stability control (ESC) and traction control.

  4. Measurement Devices: Steering angle is often measured by sensors in the vehicle's steering system. These sensors provide feedback to the vehicle's control systems, allowing for adjustments to improve stability and safety.

  5. Vehicle Dynamics: Monitoring the steering angle is essential for vehicle dynamics, especially during turns, maneuvers, and when stability control systems intervene to prevent skidding or loss of control.

  6. Steering Geometry: The steering angle is influenced by the vehicle's steering geometry, including factors such as the type of steering system (e.g., rack and pinion, recirculating ball), wheelbase, and tire characteristics.

Understanding the steering angle is crucial for optimizing vehicle handling, stability, and safety. It provides valuable information for both the driver and the vehicle's control systems to ensure proper alignment and control during various driving conditions.
