3.2.3 Heading distance indicator
This function measures the distance from the objects around vehicle and, depending on the
speed at which the vehicle is travelling, warns the driver when the safe distance from the vehicle
in front is not being maintained. The function does not intervene independently, but instead
informs the driver of the distance from other vehicle via a visual and/or audible signal.
3.2.4 Sensor data fusion
The FR5TPCC can support sensor data fusion without the need for additional hardware. Sensor
data fusion combines the benefits of different sensors and measuring principles in the most
effective way possible, providing data that individual sensors working in isolation are unable to
generate. Fusion of multiple sensors increases the measurement range, reliability and accuracy.
Video sensors, such as the multi-purpose camera or the stereo video camera from Bosch, are
the ideal supplement to radar technology. Using software algorithms, the fusion of sensor data
generates a detailed “image”, which forms the basis for an interpretation of the vehicle`s
surroundings.
Sensor fusion enables the implementation of additional assistance and safety functions, such as
pedestrian protection (“AEB Pedestrian”). The function for predictive pedestrian protection
meets the safety requirements as specified by Euro NCAP. It continually monitors, in
combination with a video camera, the area around vehicle in order to detect impending
collisions with pedestrians who are in the path of the vehicle or moving toward it in a way that is
likely to present a risk. If the function detects that pedestrians are at risk, it can actively trigger
application of the brakes in order to considerably reduce the risk and the consequences of the
collision, or to prevent the accident altogether.
Sensor data fusion can also be used to significantly improve the performance of the comfort
functions. Thanks to the high degree of lateral measuring accuracy of a video camera, the ACC
function is able, for example, to detect vehicles merging at an earlier stage, and therefore
respond in a more dynamic manner. The system also ensures that vehicles in front are
assigned to the correct lanes, which further enhances ACC functionality, especially when
cornering.
