HELLA RS 5.5 Advanced Driver Assistance System

The RS 5.5 is an advanced driver assistant system, to warn the driver of the ego vehicle against potential collisions with other road users to the side, to the rear and to the front of the ego vehicle.

This system is not meant to encourage aggressive driving. The absence of a warning will not guarantee the absence of other road users. Responsibility for the safe operation of the vehicle remains with the driver.

Functions

The sensor is capable to detect other objects. With this recognition capability it covers for example the following functionalities:

Blind-spot detection and lane-change warning

These functions monitor the neighboring lanes and warn the driver of the ego vehicle when an intended lane change could cause a collision with other traffic participants.

Rear traffic alert

This function monitors the difficult to see zone at the rear side of the ego vehicle and warns the driver against possible collisions with other moving road users when reversing out of a parking space.

Pre-crash rear

This function monitors the lane behind the ego vehicle and initiates safety measures when a crash from behind is unavoidable.

Safe exit

This function monitors the area next to the car doors on the passenger’s and on the driver’s side to the back and to the front and warns the driver if the car door cannot be opened safely.

System Architecture

The system consists of two or more radar sensor units which are mounted in the front or rear corners of a vehicle or on the left and right sides of a vehicle so that the respective peripheral sectors of the vehicle can be observed.
The units interchange data between each other and the vehicle via the sensor CAN-bus. All units incorporate an RF part and a microcontroller to perform the radar signal processing.

Technical Data

Vehicle Integration

Since RADAR waves can penetrate plastics, the sensor integration is possible behind the bumper fascia and thus invisible from the exterior. However, the plastic and other materials which surround the sensor may cause bending, refraction and reflection of the RADAR waves. Distances, clearances, selected radii and other constructive elements in their arrangement can lead to constructive or destructive interference of the RADAR waves. That must be avoided by choosing a suitable integration position.

The sensors should be positioned in the vehicle at a height of 400 to 700 mm above the road surface. If that cannot be fulfilled, then the deviating installation height must be agreed upon with Hella GmbH. & Co. KGaA.

Warning: The radar sensor should be installed and operated with minimum distance of 20 cm between the radiator and the human body.

Spatial orientation of the sensors

The RS5.5 sensors can be mounted in the front and/or rear area of a vehicle under defined angles:

Rear side integration: approx. 45 deg

Front side integration: approx. 45 deg
