CLSx – Steering Effort Sensor

The innovative steering effort sensor CLSx sets new standards in size of the housing as well as in resolution and accuracy of measurement values. The sensor is placed between steering column and original steering wheel of the vehicle, preserving all steering wheel functions.

The CLSx captures precisely the parameters torque, steering angle and rotational velocity. Optionally, it also acquires acceleration in the center of the steering column (x, y and z direction) as well as rotational acceleration.

Measurement data are digitized for a highly fail-safe data transfer, with a resolution of 16 bits (internally: 24 bits). Together with its innovative, ultra slim sensor body design, this leads to an unprecedented precision of torque measurement of 0.1% FS.

Highlights

  • Ultra slim sensor body design for seamless integration with minimal extension of steering column
  • All functions of the steering wheel are preserved
  • Steering torque range ±100 Nm
  • Measuring angle range ±1440 °
  • Rotational velocity range ±1000 °/sec
  • Acceleration in x, y, z direction
  • Rotational acceleration

For data output and parametrization, the receiver and control unit offers both analog and digital interfaces (CAN, Ethernet). At the 2.83″ Farbdisplay (320 x 240 px) integrated in the control unit, all measurement values are displayed in physical dimensions.
