Bourns introduced a new Combined Torque and Angle Sensor designed for Electric Power Assisted Steering Systems (EPAS) and other automotive systems. The new combined torque & angle sensor provides torque and steering angle measurement in a single package, replacing two discrete sensors for significant space and cost savings. Based on Bourns’ Hall Effect (HE) non-clockspring torque sensor technology, the combined sensor uses driver input to measure the steering torque while simultaneously converting the rotation speed and direction of the steering wheel. The torque portion of the sensor is designed specifically for Electric Power Assisted Steering System, and the steering angle signal can be used in a variety of automotive systems including Electronic Stability Control (ESC), Advanced Front Lighting Systems (AFLS), Advanced Vehicle Navigation, and Assisted Parking Systems.

Combined Torque & Angle Sensor for Electric Power Assisted Steering (EPAS) SystemBourns offers several variations of its new combined torque and angle sensor to meet customer requirements. Variations include dual and single channel options on the torque portion depending on redundancy requirements, and the steering angle sensor can support incremental or absolute measurement.

The new Bourns® Torque and Angle sensor is suitable for column or rack mounted EPAS. For rack-mounted applications, the combined Torque and Angle sensor has been designed to sustain temperatures from -40°C to +125°C. The new device provides CAN steering sensor output in addition to an analog torque signal. The torque sensor output can also be configured to support CAN, analog, PAS4, PSI5 and PWM outputs.
