The collision avoidance system CAS-M light helps the driver to focus on the track and warns him if a car is approaching from behind. The system provides information about relative speed and distance of the closest vehicle on the CAN bus. An additional display with CAN bus interface is required (e.g. DDU 9).
The information is based on a Bosch radar sensor which contains a FMCW radar transceiver operating in the frequency range of 76.0 - 77.0 GHz. Targets in front of the sensor are reflecting the radar signal and the relative speed and distance is determined via Doppler-effect and beat frequency.
The benefit is even more increased during darkness or in bad weather conditions. The system interface is very intuitive and adaptable to the drivers liking.

Installation Notes
The system includes a radar sensor and a detailed user manual. |
Ordering information for suitable wiring looms for the different CAS-M light packages are specified in the user manual. |
The system needs to be connected to the vehicle CAN bus (connection to display needed) and supplied with 12 V from the supply system on board. |
The rear unit must be mounted 90° to the vehicles vertical and horizontal axis and within ± 200 mm of the vehicle lateral centerline. |
Mounting distance of radar over ground: 300 to 1,000 mm |
To achieve the expected performance from the radar sensor, it must have a clear and unobstructed view. There should be no material over the radar sensor and the sensor should be allowed a clear 180-degree field of view. |
The system needs yaw rate and vehicle speed information. |
Cat 6 A standard for Gigabit Ethernet. |
