|Autonomous driving steering angle sensor.|
Cars manufacturers are starting to remove the steering wheel and pedals in their path to fully autonomous self-driving but they still need sterring angle feedback for a closed loop safety systems, vehicle stability and electronic park assist. With hollow shaft and touchless sensors, Piher provides a "plug and play" angle feedback devices able to withstand the toughest conditions.
Our advanced driver assistance steering angle sensors have been designed for extreme environments and will securely convert mechanical motion / position to electrical feedback of the steering actuator to the microprocesor.
Sealing, protection agains external magnetic fields, redundancy, integrated temperature compensation and high-end materials assure that the device will not need maintenance during the whole driverless car´s life.
In contrast with incremental sensors, Piher sensors' output is absolute, so the position output will not be lost if a power outrage occurs.
Electronic Power Steering (EPS) is a must for self-driving cars where an array of sensors feed the main CPU that actuates the steering column.
Tear and wear free, our hall-based sensors provide absolute position sensing to the control unit that will allow the control unit calculate the rotation direction and speed.
The PST-360 angle sensor can assist the following systems too:
Magnetic angle sensors technology you will find in the market are Hall Effect, Variable reluctance, Giant Magneto Resistive. Piher uses improved Hall Effect position sensing for electrified powertrain, connected infotainment, body, shassis, safety, and driver information position.
Regarding the steering wheel switches, we can manufacture a variety of fail-safe products (linear and rotary movement detectors) for:
These can be printed PCB based, printed potentiometers or hall-effect switches.
Autonomous driving,ADAS and human machine interfaces are gaining traction worldwide while Piher launches a wide range of advanced sensing and control technologies.
