ContiSense uses a combination of electrically conductive rubber compounds and rubber-mounted sensors to collect and send information from the tire to the vehicle control system.
The system has three main components: the Electronic Control Unit (ECU), the Actuator Control Unit (ACU) and a reservoir which collects the returned brake fluid.
The ACU is made up of components such as an integrated Power Transmission Unit (PTU), valves, the simulation chamber and the brake master cylinder.
The IMU is required for positioning the vehicle in the lane as well as for electronic stability control and other safety functions. To increase the functional safety for automated driving, two independent units are recommended.
Gen5 Short-Range Corner Radar sensors support functions such as the „Observation Assist”. Environment can be detected within a range of up to 90 meters in a grid of 20 centimeters and an opening angle of +/- 75 degrees.
The Safety Domain Control Unit is capable to integrate complex active and passive safety functions.

The HADP has been developed based on an ASIL-D (Automotive Safety Integrity Level) functional safety concept.
