1. Steering Torque
Redundant steering torque information delivered by two sensors is essential for the drive of the steering assist motor. Micronas' Linear Hall sensors are used for magnetic field amplitude measurement offering low-noise and low-offset drift capabilities. Analog output and digital output (PWM or SENT) are available. Redundant sensor bring cost advantage
Sensor Type: Linear

2. Steering Angle
2D Hall-effect sensors measuring angles up to 360° are a cost-efficient solution for a contactless steering position measurement. The devices support state-of-the art interfaces like PWM and SENT.
Sensor Type: 2D

3. Steering Motor - BLDC Motor
As part of the power steering system, Hall switches are used for BLDC motor commutation. To reduce the overall current consumption, the HAL 1502 3-wire version with only 1.6 mA is preferred.
Sensor Type: Switch

4. Chassis position sensor
The chassis position sensors (CPS) are located near the vehicle's front and rear axes. They determine the vehicle’s current position and adjusts the range of the main headlights accordingly. CPS requires angular sensors with full 360° measurement range, which is usually split into four segments of 90° or three of 120°. The interface is usually analog, PWM, or recently also PSI5.
Sensor Type: 2D

5. Braking Pedal
A 2-wire unipolar Hall switch or a 2D Hall sensor can be used to detect when the brake pedal is pressed. As price attractive solution, the switch determines when the pedal has passed a certain position whereas the 2D sensor measures the complete angle/movement of the pedal, providing higher safety.
Sensor Type: Switch, 2D
