As a world-leading automotive technology and service provider, Bosch continues to focus on innovations in safe driving technology and develops future-oriented driver assistance systems. These systems can be started at a speed of 0-50 km/h, automatically braking, accelerating, and steering the vehicle for traffic conditions that frequently start and stop. When faced with traffic jams, they greatly reduce driving intensity and relieve traffic congestion. Play an important role.
It is reported that in 2014, the first-generation Bosch traffic congestion assistance system will enter volume production. In the future, Bosch will also continue to improve the system, apply it to higher speeds and more complex driving conditions, and put it into the highway test, eventually achieving unmanned driving. Gerhard Steiger, President of Bosch Chassis Control Systems, stated: "The Bosch Traffic Congestion Assistance System enables vehicles to easily reach their destination in the event of intensive traffic."
At present, the adaptive cruise control system has been able to follow the front car automatically adjust the distance and speed. The system, with the support of a lane detection camera and an electromechanical steering system, combined with the electronic stability program ESP, constitutes the basis for driverless technology.
Nowadays, powerful software systems have been able to calculate safer and easier driving routes, and controlling the vehicle's ability to automatically change lanes will be the next step toward unmanned driving. This requires the addition of two additional configurations: First, assembly. The radar sensor at the rear of the vehicle body can monitor the rapid approaching vehicle at the rear; the second is the dynamic navigation map, which can update the road conditions and the road speed limit in real time through the mobile internet. Although drivers are still responsible for driving, they can more easily monitor the driver assistance system's actions and status.
In addition to ESP æ‚– and electronic steering, Bosch also comprehensively provides the sensors needed to assist in driving, real-time monitoring of various traffic conditions around the driver and the vehicle. According to the functions of the vehicle configuration, the front detection can be realized by a radar sensor plus a monocular camera or a stereo camera. For example, Bosch offers a high-performance long-range radar sensor (LRR3) capable of detecting sector areas up to 250 meters in front of the vehicle and an angle of 30 degrees; the new mid-range radar sensor to be mass produced in 2013 covers 45 degrees and 160 meters. In terms of scope, this radar is designed for high-volume markets, and the scale effect will significantly reduce costs. In addition to the existing multi-camera based on a single lens sensor, Bosch has developed a 3D stereo camera using a dual-lens sensor that not only accurately calculates the distance of the detected object, but also recognizes its direction of movement. Both cameras can be used in predictive emergency braking systems. In addition, Bosch offers two-sided rear mid-range radar sensors for detecting objects within 150 degrees behind the body, up to 100 meters away. Finally, Bosch Park Assistant's ultrasonic sensors are used to assist close-range steering operations.
Gerhard Steiger said: "Automotive technology will eventually evolve toward the unmanned target." It is reported that greater autonomy and higher speeds on highways will become possible, eventually achieving full-automatic driving. At present, unmanned driving still faces two major challenges: First, the city driving environment with dense traffic and inconsistent directions; second, it is a system concept that can operate reliably in various driving environments.
