The 2020 International Consumer Electronics Show (CES? 2020) will officially kick off on January 7 in Las Vegas. At this exhibition, Bosch will continue to fulfill its brand promise of "technology creates the beauty of life" and will bring a variety of products in the fields of mobile Internet travel and home Internet to its booth No. 12401 in the central exhibition hall. In the field of travel, Bosch mainly focuses on the two major trends of automobile intelligence and electrification, displaying a series of innovative technologies to empower future travel.
Intelligent technology: unlocking smart car life
●?3D display screen
As an important entrance to human-computer interaction, the new generation of digital display screen is becoming more and more popular with users. The focus on excellent driving experience continues to increase, and cars are gradually moving towards the pursuit of larger sizes, stronger visual effects, and more functions. Especially in terms of functionality, according to current trends, digital displays in future cockpits will continue the display and control functions on smart devices such as mobile phones and TVs, playing a key role in the interaction between drivers and vehicles.
Bosch’s new 3D display is designed to respond to this trend. This product uses passive 3D technology to generate a realistic three-dimensional effect. Compared with traditional displays, it helps drivers capture important visual information faster and reduces distraction. For example, when parking, the more realistic rear view image can help detect obstacles in time and help the driver better grasp the remaining space between the rear fender and the parking lot wall. In densely built city blocks, a map with a three-dimensional view allows the driver to clearly understand which building to turn. "We make vehicle reminders seem as if they are jumping out of the screen, which will be more intuitive and more urgent," said Steffen Berns, global president of Bosch's Automotive Multimedia Division.
Not only that, the passive 3D technology installed in Bosch’s new 3D display can be used without the need for drivers and passengers to wear 3D glasses or use visual tracking technology. It can be described as the latest development trend in the current vehicle cockpit.
●?In-vehicle monitoring system
According to relevant statistics, about 1.35 million people are killed in road traffic accidents around the world every year, and a large part of these accidents are caused by human factors. Caused by drunk driving, speeding, distracted or fatigue driving, etc. Therefore, it is particularly important to adopt appropriate methods to monitor the status of drivers and passengers in real time to provide early warning of potential risks.
To this end, Bosch has developed a new in-car monitoring system that combines cameras and artificial intelligence. The system mainly monitors the driver's drowsiness, distraction, head turning to passengers and rear seats through a camera installed on the vehicle's steering wheel in real time, and then relies on artificial intelligence technology to analyze the video information and make correct judgments: According to relevant In compliance with laws, regulations and car manufacturers' requirements, the system can issue early warnings to distracted drivers, advise fatigued drivers to take a break in time, and even rely on the autonomous driving system to help the vehicle reduce its speed and improve driving safety.
Take driver fatigue monitoring as an example. The in-car monitoring system can judge the driver's fatigue level by recording the driver's eyelid position, blink frequency and other information, so as to issue early warnings in a timely manner and make timely use of the driving information. The driver assistance system can effectively intervene. In human-machine autonomous driving scenarios, the system can analyze camera records to determine whether the driver is in a suitable state to control the steering wheel, thereby determining the best time to hand over vehicle control to the driver.
Not only that, the in-car monitoring system can also identify different drivers and adjust the rearview mirror, seat position, steering wheel height and infotainment system according to personal preferences, or use the recognition function of the camera , allowing the driver to control the infotainment system through sight and gestures, greatly improving the comfort and convenience of the driving experience.
In addition to monitoring the driver, the system can also monitor the status of other occupants in the car, thereby optimizing safety systems such as airbags to provide better protection when an emergency occurs. This function is mainly achieved by monitoring the entire cockpit through a camera installed above or below the rearview mirror. For example, when a child in the rear seat inadvertently releases the seat belt, and the rear passenger leans too far forward or has his or her feet on the seat next to him, causing the airbag and seat belt pretensioner to fail to provide adequate protection in the event of an accident. The system will promptly warn the driver.
The system can also play a good role in monitoring children in parked vehicles, effectively identifying potential dangers in such scenarios.
●Smart front-facing camera
This smart front-facing camera can accurately distinguish different types of road users such as vehicles, pedestrians, and cyclists, and evaluate them. movement path. In congested urban traffic, smart front-facing cameras can quickly and reliably identify and distinguish partially obscured vehicles, pedestrians and cyclists, thereby triggering vehicle alarms or emergency braking in a timely manner.
This camera’s ability to analyze the road environment is also excellent. Even in the absence of road signs, the camera can accurately distinguish lanes, turf shoulders or roadside buildings to assist safe driving.
●?Radar sensor
At present, Bosch's radar sensor has developed to the fifth generation of products. The new generation of Bosch radar sensors is better at capturing the vehicle's surroundings, improving the response of the automatic emergency braking system even in bad weather or poor light conditions thanks to its wider detection range, wide aperture and high angular resolution. Driving safety.
●? Automatic Valet Parking
As early as July this year, the AVP automatic valet parking system (SAE-L4 level autonomous driving) jointly developed by Bosch and Daimler ) obtained the world's first license without human supervision in Germany and was allowed to be used in the parking lot of the Mercedes-Benz Museum. For vehicles equipped with this system, the owner only needs to drive the car to the entrance of the parking lot and leave. The vehicle will automatically find a parking space and park under the guidance of the system. When the car owner needs to pick up the car, he only needs to summon it through the mobile phone APP or the parking lot terminal, and the vehicle can automatically drive out of the parking space and arrive at the parking lot exit.
Unlike many companies, the technical core of the Bosch AVP system is field-side master control. Whether it is a new or existing parking lot, you only need to deploy corresponding sensors at specific locations, scan the entire parking lot in real time, plan the corresponding route, and issue the entry route to the T-BOX in the vehicle through V2X technology. Can direct the movement of vehicles. In this system, Bosch mainly provides the sensors and communication technology that serve as the infrastructure in the parking lot.
Bosch expects that parking lots in many countries will be equipped with this service by the end of 2021. To this end, Bosch is cooperating with a number of parking lot managers and developers of important real estate projects. Among them, in China, Bosch mainly cooperates with GAC, China Mobile, etc. in the research and development of this system.
●?Vehicle computers
Currently, Bosch is developing on-board computers for autonomous driving, powertrain systems, vehicle infotainment systems and driver assistance functions. Bosch's on-board computer can not only significantly improve computing power with the help of new high-performance vehicle control units, but also reduce the weight of the vehicle by reducing the number of electronic control units and simplify the interaction between components and systems. It is expected that by the beginning of 2020, the computing power of Bosch's on-board computers will increase by about 1,000 times compared with the current level.
●? Smart keyless
The smart keyless system can achieve a comfortable and convenient car experience such as keyless entry and start, remote key authorization for others, and personalized vehicle settings. It truly frees up car owners’ hands and leaves their car keys at home. In the future, the system will not only be able to communicate via Bluetooth, but also use ultra-wideband to communicate between vehicles and smartphones. At present, some smartphones have used ultra-wideband, a new communication technology, to make the positioning function of smartphones accurate to the centimeter level and fully ensure communication security. At this year's International Consumer Electronics Show, Bosch will use ultra-wideband technology for the first time in a demonstration car equipped with an intelligent keyless system. In order to better promote this technology, Bosch and its partners are working to standardize data transmission between smartphones and vehicles.
