Steering torque and angle sensor

Steering torque and angle sensor

The combined steering torque and angle sensor from HELLA is integrated in the electromechanical power steering and offers the customer two types of feedback:
  • Steering torque:
  • The sensor records the torsion bar angle required for the steering movement.
  • Steering angle:
  • The sensor measures the angle and speed of change in the position of the steering wheel

Both sensor functions are integrated in one sensor and benefit from HELLA’s proprietary CIPOS® technology.

 

Advantages

  • Modular sensor design for all types of electromechanical power steering (EPS)
  • System integration capability with HELLA EPS
  • Diversification of technologies (inductive and Hall)
  • Absolute angle information for output and input shaft
  • Ratiometric measuring principle to improve accuracy over total measurement range
  • Freely programmable torque range with up to +/- 8°
  • Intelligent software concept for increased safety
  • No need for additional steering angle sensor in the steering column
