How do you find out steering angle of a vehicle ?

To determine the steering angle of a vehicle as it moves, you can use various methods and sensors. Here are a few common approaches:

Onboard Sensors:Many modern vehicles are equipped with sensors, such as a steering angle sensor, that directly measure the position of the steering wheel. This sensor provides real-time data on the steering angle. You can access this information through the vehicle's onboard diagnostics (OBD) system.

GPS and Inertial Measurement Units (IMUs):Using GPS and IMUs can provide information on the vehicle's position, velocity, and orientation. By processing the data from these sensors, you can estimate the steering angle. Keep in mind that this method might have limitations in accuracy and may require advanced algorithms for reliable results.

CAN Bus Data:The Controller Area Network (CAN) bus in a vehicle carries information between various components. Steering angle data may be available on the CAN bus, and you can access it using an OBD-II (On-Board Diagnostics) device or a dedicated data logger.

Aftermarket Steering Angle Sensors:If your vehicle doesn't have a built-in steering angle sensor, you can install an aftermarket steering angle sensor. These sensors are designed to measure the angle of the steering wheel and can be integrated into your vehicle's system.

Telemetry Systems:Some vehicles, especially those used in motorsports, may be equipped with telemetry systems that provide real-time data, including steering angle. These systems often use a combination of sensors and wireless communication to transmit data to a remote receiver.

Camera-Based Systems:Computer vision techniques using cameras can be employed to track the position of the steering wheel. This method involves image processing algorithms to analyze frames and determine the steering angle.

Mechanical Measurement:In some cases, a physical measurement of the steering system, such as attaching a rotary encoder to the steering column, can be used to directly measure the steering angle.

When selecting a method, consider factors such as accuracy requirements, cost, ease of implementation, and the specific goals of your measurement. Keep in mind that the accuracy of the steering angle measurement may be influenced by factors such as tire characteristics, suspension system, and road conditions. Additionally, ensure that any modifications or additions to your vehicle comply with local regulations.

Hello Nouman khan Usama,

Most popular method is to calibrate steering weel rotation and steering wheel sensor placed on steering rack or in the steering column and then recalculate based on this calibration.

But You will not get slip angle.
