In addition, in terms of highly automated driving, Bosch and Daimler have already launched the corresponding scene application demonstration of the automatic valet parking technology in Beijing, and cooperation with local host manufacturers such as the GAC Research Institute is also gradually being carried out.
This year, Bosch has further combined EV robot charging with automatic valet parking technology, allowing electric vehicles to automatically complete the parking and charging process without manual intervention, improving the utilization efficiency of electric vehicle charging piles, and thereby solving electric vehicle mileage. anxiety.
In the field of connected transportation, Bosch demonstrated its latest cockpit domain controller, the world's first mass-produced car's curved instrument display, 3D display, vehicle OTA remote upgrade, digital key and other cutting-edge technologies.
The cockpit domain controller is equipped with Qualcomm 8155 chip and integrated multi-module operating system. It can support multiple displays such as instrumentation, central control, co-drive entertainment, HUD, air conditioner, rear row, etc., and integrates driver and occupant monitoring (DOMS). ), 360 surround view (AVM), and face recognition (Face ID), multi-microphone input, active noise reduction and other functions.
Bosch's remote vehicle upgrade solutions are also evolving in accordance with the needs of the industry. It has expanded from the SOTA (Software Over The Air) upgrade of the infotainment system and the FOTA upgrade of the entire vehicle ECU to the remote measurement and remote measurement that support the entire life cycle of the vehicle. The overall solution of cloud diagnosis, big data platform and algorithm.
In addition, Bosch is cooperating with China Mobile to incubate FOTA SaaS (Software as a Service) to provide small and medium customers with fast and easy-to-use solutions.
Bosch's digital key can turn the owner's smartphone into a car key, providing a comprehensive and secure service plan from the car end, the mobile phone end to the background cloud, and the call center.
While Bosch has brought many new technologies this year, it has also not forgotten its strategic layout of "three modernizations". At the 2020 Beijing Auto Show, Stefan Hartung, a member of the Board of Directors of Bosch Group and Chairman of the Automotive and Intelligent Transportation Technology Business Unit, revealed that Bosch will continue to invest more than 1 billion euros in the aforementioned new technologies this year to help accelerate the transformation and upgrading of automobiles and intelligent transportation, and enable mobility. Safer, sustainable and exciting. Especially China, as one of Bosch's most important strategic markets, will be the top priority of Bosch's layout.
Among them, in terms of electrification, Bosch has built a complete solution including motors, electric bridges, power electronic controllers, on-board charging and distribution units, 48V systems, braking and steering systems based on years of vigorous investment and development. , And continue to expand the product line. For example, in terms of silicon carbide, Bosch launched its newly developed power device at the Beijing Auto Show. This product can help electric vehicles and hybrid vehicles increase their cruising range by about 6% and greatly reduce energy consumption. It is worth mentioning that this is also the first appearance of this technology on a global scale.
Similar to electrification, autonomous driving is also the direction Bosch is vigorously deploying. In this field, Bosch has adopted a gradual development strategy to gradually promote mass production of autonomous driving. At present, at the level of L2 autonomous driving, Xu Daquan revealed that Bosch has more than 60 projects in the world that have entered mass production, including TJA traffic jam assistance, APA automatic parking assistance, etc. The next step that will be put into mass production is RPA remote parking assistance. And highway assist system.
What supports Bosch's breakthrough in the field of autonomous driving is its complete layout of the autonomous driving product line. For example, in the perception layer, Bosch has built a comprehensive sensor product portfolio, including super isowave radar, camera, millimeter wave radar, lidar and so on. Among them, Bosch's millimeter-wave radar has developed to the fifth generation, and the camera has developed to the third generation. The first long-range lidar suitable for vehicle regulations has also entered the mass production development stage. By complementing lidar with cameras and millimeter-wave radars to provide drivers with reliable road condition information, Bosch is helping the automotive industry accelerate the realization of L3-5 autonomous driving.
At the decision-making level, Bosch launched the domain controller DASy, which is a core component of a centralized vehicle architecture with high bandwidth, strong computing power, large storage capacity, and high security. DASy can collect and fuse data from sensors such as radars, cameras, lidars, etc., to help vehicles generate a 360-degree high-precision environment model around them and formulate appropriate driving strategies.
As for the executive level, such as the braking system and steering system, it is also Bosch's strength. In this field, Bosch’s most mature product is the iBooster+EPS combination. Both systems have direct mechanical propulsion devices and can independently brake the vehicle throughout the deceleration range to form brake redundancy, thereby ensuring that the vehicle is in It can brake safely under any circumstances.
It can be said that it is with such a rich product portfolio that Bosch's autonomous driving mass production plan can be advanced in an orderly manner. With the rapid development of the “four modernizations” of automobiles, the value of automobile products is gradually shifting from hardware to software, and “software defines automobiles” has thus become an industry consensus.
As the world's leading technology and service provider, the Bosch Group's current business covers automotive and intelligent transportation technology, industrial technology, consumer home appliances, and energy and construction technology.
