Co. KGaA 59552 Lippstadt Ref.:
The RS 5.3 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. d e v r e s e r e r a s t h g i r l l A

Co. KGaA 59552 Lippstadt This function monitors the lane behind the ego vehicle and initiates safety measures when a crash from behind is unavoidable. 1.4 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. d e v r e s e r e r a s t h g i r l l A

Co. KGaA 59552 Lippstadt System Architecture 2 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. d e v r e s e r e r a s t h g i r l l A

Co. KGaA 59552 Lippstadt Vehicle Integration 3 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. 3.1 Spatial orientation of the sensors The RS5.3 sensors can be mounted in the front, side and/or rear area of a vehicle under defined angles:
Rear side integration: approx. 45 deg Side integration: approx. 90 deg Signed by:
