Bosch video-based emergency braking fitted as standard in Land Rover Discovery Sport
- Bosch stereo video camera is single-sensor solution for assistance systems
- Land Rover Discovery Sport received top Euro NCAP ‘safety assist’ score
- Bosch stereo video camera for automotive applications is smallest on market
- 3D imaging capability is an important building block for automated driving
Emergency braking systems are among the most effective assistance systems in the car. It is estimated that three out of four rear-end collisions resulting in personal injury could be avoided if all vehicles were equipped with them. Bosch has developed a stereo video camera with which an emergency braking system can function based solely on camera data. Normally, this would require a radar sensor or a combination of radar and video sensors.
“The Bosch stereo video camera is a single-sensor solution that makes various assistance functions affordable for all vehicle classes,” says Dr. Dirk Hoheisel, who sits on the Bosch board of management. Land Rover offers the stereo video camera together with the Bosch emergency braking system as standard in its new Discovery Sport. This system was developed in intensive and close collaboration between Bosch and Land Rover.
The Discovery Sport proved how effective the function is in a Euro NCAP test: it was rated as ‘good’ in the AEB city and AEB interurban categories. Overall, the Discovery Sport passed the test with five stars and achieved one of the best results in the ‘safety assist’ category for 2014. The Discovery Sport has also been awarded the What Car? Car of the Year Safety Award 2015 in the UK.
Important building block for automated driving
Besides the emergency braking system, the new Land Rover Discovery Sport offers other driver assistance functions, some of which are also based on the Bosch stereo video camera. One such function is road-sign recognition, which keeps the driver informed about the current speed limit. Another is a lane-departure warning system.
“The Bosch stereo video camera and its 3D imaging capability are also an important building block for automated driving,” says Hoheisel. Its pair of highly sensitive video sensors are equipped with colour recognition and CMOS (complementary metal oxide semiconductor) technology. They have a resolution of 1,280 by 960 pixels and can also process high-contrast images.
The smallest stereo video camera currently on the market
One of the biggest advantages offered by the Bosch stereo video camera is its compact design. The distance between the optical axes of the lenses is just twelve centimetres, making this the smallest system of its kind currently available in the field of automotive applications. Bosch developers have integrated the control unit for image processing and function control directly into the camera housing. That means vehicle manufacturers can integrate the camera into the rear-view mirror especially easily, impeding the field of vision only slightly.
“We’re pleased to say that Bosch developed the entire stereo video camera in house from start to finish,” says Hoheisel. As a result, all components, from hardware to image processing to the functions, are designed to work together seamlessly.
