What steering wheel position sensors are utilized in cars?

In today's cars, wheel position sensors play a key function in ensuring safety and driving performance. These advanced devices monitor steering movements and transmit information to different car systems specified as steering, track stabilisation systems, steering support systems and more. In this article, we will look at different types of sensors for the position of the steering wheel utilized in cars.

Rotary angle sensors

One of the most crucial types of steering wheel position sensors are steering angle sensors. These sensors monitor the degree of steering and transmit this information to the car systems. Thanks to this, track stabilisation systems can adjust the operation of the steering strategy to guarantee optimal control of the vehicle.

Rotary angle sensors can be based on different technologies specified as Hall sensors, magnetic sensors or optical sensors. Each of these technologies has its advantages and disadvantages, but all are aimed at carefully monitoring the steering angle.

Rotary torque sensors

Another kind of steering wheel position sensors are torque sensors. These sensors measurement the force with which the driver turns the steering wheel. This information is highly crucial for steering support systems that can adjust the assistive force according to the driver's preferences.

The torque sensors may be based on different technologies specified as opposition sensors, magnetic sensors or optical sensors. Each of these technologies has its advantages and disadvantages, but they all aim to closely monitor the torque of the steering wheel.

Angular velocity sensors

Another crucial kind of steering wheel position sensors are angular velocity sensors. These sensors monitor the velocity at which the steering wheel is rotated by the driver. This information is utilized by track stabilisation systems that can adjust the operation of the steering strategy depending on the velocity of the turn.

Angular velocity sensors can be based on different technologies specified as opposition sensors, magnetic sensors or optical sensors. Each of these technologies has its advantages and disadvantages, but they all aim to closely monitor the angle velocity of the steering wheel.

Pressure sensors

The last kind of steering wheel position sensors are force sensors. These sensors measurement the force with which the driver holds the steering wheel. This information is utilized by track stabilisation systems that can adjust the operation of the steering strategy according to the driver pressure.

Pressure sensors can be based on different technologies specified as opposition sensors, capacitive sensors or optical sensors. Each of these technologies has its advantages and disadvantages, but they all aim to closely monitor the driver's force on the steering wheel.

Summary

Steering wheel position sensors are highly crucial elements in today's cars. Thanks to them, car systems can monitor steering movements and adjust the operation of the steering system, track stabilisation systems and steering support systems. The steering angle, torque, angular velocity and force sensors are essential for ensuring safety and driving performance. Therefore, car manufacturers continuously improve these technologies to guarantee maximum precision and reliability.
