Bosch presents traffic safety solutions
At the Mobile World Congress 2017 in Barcelona, which ended yesterday, Bosch presented smart new solutions for use in the Internet of Things (IoT). Occupying center stage was a concept car with a number of automated driving features. In addition to conveniences such as keyless entry, the automobile offers in particular innovative safety features: if the driver begins to fall asleep, or is considerably distracted, the Driver Drowsiness Detection feature can cause the car to emit a warning signal, and thus prevent a dangerous situation.
The concept car is also the first to offer gesture-controlled operation with haptic feedback. The technology makes use of ultrasound sensors, which allow drivers to feel whether their hand is in the right place. They also give the driver feedback regarding the gesture that has been performed. This, in turn, makes it possible to operate infotainment programs without looking at the controls, and driver can this keep their eyes on the road for much more of the time. In addition, the exterior rear-view mirrors have been replaced by a “Mirror Cam System,” which displays the car’s surroundings with the help of sensors and display screens. What is really special is that when the car is on the highway, the camera automatically extends the viewing angle farther back behind the car, and when in the city, the viewing angle is as wide as possible, to enhance safety. At night, increased contrast levels enhance the driver’s ability to perceive his or her surroundings.
A cloud-based wrong-way-driver warning system
Furthermore, Bosch has developed a cloud-based system that transmits warnings about wrong-way drivers. This system sends information to both the wrong-way driver and to drivers in oncoming vehicles within ten seconds – faster than with a radio-based system. In order to detect a vehicle driving in the wrong direction, the cloud-based feature compares the actual movements of the vehicle with permitted directions as listed in an Internet-based database. The function depends on the regular, anonymous reporting of the vehicle’s position to the cloud – a centrally located computing center in which data from the Internet can be stored and analyzed. The more vehicles are in the network, the greater the system’s capability for providing comprehensive notification of wrong-way drivers.
On the path toward greater road safety, Bosch is also testing a new solution for providing direct communication between vehicles: In this system, networked cars send information regarding speed, position and lane changes directly to all vehicles within a radius of 320 meters – without any detours whatsoever, and thus, without any delay. The rapid and direct communication between cars serves to optimize the flow of traffic, and is designed to help prevent accidents. The new technology is called LTE-V2X and is currently being tested live in cooperation with Vodafone and Huawei on the test section of the A9 Autobahn near Allershausen, Germany.
