1 Further improve the energy efficiency of the car
This article refers to the address: http://
As the world's number one supplier of auto parts and systems, Bosch clearly has a wealth of scientific research experience and technical reserves in this era of new energy, car networking and autonomous driving. Therefore, at the international media exchange held in the Boxberg test site in Bosch, Germany, we saw Bosch's efforts and achievements in the electrification, interconnection and automation of automobiles. The ultimate goal of these technologies is to make vehicles more efficient. It's safer and the dream of people's long-term autonomous driving.
â— Electrification: further improve the energy efficiency of the car
Today, the power unit of a car is not limited to two internal combustion engines, gasoline and diesel engines. Hybrid systems and electric motors are becoming more and more familiar and accepted. However, in Bosch's view, today's internal combustion engines still have their own advantages and potentials, so they will still serve as the basis for efficient transportation in the future. To date, Bosch has supplied millions of steam/diesel direct injection systems worldwide, and has also contributed significantly to hybrid/pure electric technology. In addition, the new start-stop technology and CNG dual-fuel technology based on the traditional internal combustion engine architecture will also increase the fuel consumption and cruising range of the vehicle to a new level.
- Tax stop and stop technology
At present, the existing start-stop system can only shut down the engine when the vehicle is completely stopped, and the taxi start-stop system can shut down the engine when the vehicle is coasting (such as a high-speed downhill ramp), and at the same time, in the automatic transmission model, the system can be The clutch is automatically controlled to separate the engine from the drive train to extend the coasting distance. When the driver operates the throttle or brake pedal during taxiing, the engine will start quickly. Although the existing engine control system can stop the engine from injecting when the vehicle is coasting, the taxiing distance is not long because the engine and the transmission system are not separated, and the engine will still spray when the neutral is coasting, although it can be long Sliding distance but not fuel-efficient. Therefore, the taxi start and stop system can combine the advantages of these two working conditions, achieve the purpose of fuel saving by means of flameout, and at the same time make the vehicle slide longer.
- Compressed natural gas (CNG) dual fuel technology
In many areas of China, taxis that use natural gas as fuel can be seen. Even some private car owners in cities will choose to carry out related modifications in the aftermarket. Although these later-modified natural gas fuel vehicles are not as good as the front space, power performance and safety, the fundamental reason for these owners to choose to compromise is the low cost of use. In addition, natural gas has an advantage over gasoline in terms of emissions. Therefore, Bosch and Audi jointly developed the g-tron dual fuel system, which aims to enable consumers to enjoy the economics of CNG models while ensuring high safety without sacrificing practicality. This g-tron dual fuel system can reduce the cost of fuel use for consumers in Europe by at least 50%. In the domestic market, if the price of the vehicle is only slightly increased, it is believed that there will be many owners who are pursuing economical choice. Dual fuel technology.
When various electric/hybrid models are popular and alternative energy technologies such as fuel cells are coming, many people have asserted that the traditional internal combustion engine will go, but Bosch does not think so. As one of the originators of fuel injection technology, Bosch insists today that internal combustion engines are still the basis of efficient transportation, and the assistance of more new electrification technologies will further explore the energy saving potential of internal combustion engines. However, Bosch is also advancing the progress of new energy technologies, including the cooperation with Japan's Yuasa and Mitsubishi to develop a new generation of lithium batteries. It also shows that the giant behind this will also play an important role in the future of electric vehicles.
2 Make the vehicle smarter â— Connected: Make the vehicle smarter
"A connected car is always the smarter car." When the person in charge of the Bosch vehicle interconnection business said this, I believe that there is enough confidence and confidence. Internet of Vehicles is a very hot word in recent years, and how to connect vehicles to the world and use the network to achieve more functions is the long-term efforts of various car companies and suppliers. In addition to the in-vehicle interconnection system mySPIN and the virtual cockpit technology applied to the Audi Q7 and TT models, Bosch also brought two interconnected systems in the field of intelligent transportation, which respectively allowed the vehicles to travel. Safer and more efficient.
- Predictive hybrid system
At present, the control unit in the hybrid power system can only automatically switch between the pure electric, hybrid and charging modes according to different operating conditions of the vehicle. However, there are times when we prefer to use the power in a hybrid battery pack in a congested urban area, a turtle speed section due to an accident or road repair, and a section with a lower speed limit. If the vehicle is driving to these sections, the battery power. Insufficient, the ideal fuel economy can not be achieved. The predictive hybrid system can predict the occurrence of these sections in advance by accepting traffic information from the network, and activate the charging mode to prepare sufficient power before these vehicles enter these sections to achieve more efficient driving.
- Wrong road warning system
According to Bosch's report, about 2,000 traffic accidents each year are caused by the driver entering the wrong road (retrograde or forbidden), so the original intention of the wrong warning system is to reduce the probability of such accidents. The system uses the on-board camera and the Bosch electronic horizon integrated road information system, or GPS and cloud computing to determine whether the road ahead of the vehicle is correct. When the vehicle goes to the wrong lane, the system will alarm and also use the network to send warning messages to other road users to avoid accidents.
When cars and cars, cars and roads, cars and the world are interconnected, the driving experience will be safer, more convenient and more comfortable, and more environmentally friendly. In this information age, Bosch hopes to turn cars into an integral part of the Internet, thereby further improving the efficiency of urban transport.
3 Auto-driving is ready to go â— Automation: Auto-driving is ready to go
Autopilot is a long-standing dream of mankind. Now with the development of technology, we are infinitely close to this dream. For Bosch, due to the successful acquisition of ZF's electronic steering business, the last piece of the puzzle required to achieve autonomous driving is now in place. At Boxberg, Bosch presented the world's latest highly automated prototypes to the world, as well as solutions for the safety of the automated driving system.
- Highly automated driving system
According to the definition and classification of the automatic driving technology by the German Federal Transportation Research Institute (BAST), the vehicle automatic driving technology is divided into four stages: 1. driver assistance system; 2. partial automatic driving; 3. high automatic driving; 4. complete Autopilot. The highly automated driving system demonstrated this time marks that technology is no longer a barrier and obstacle to achieving autonomous driving. Bosch already has all the technical requirements for autonomous driving.
- Autopilot system redundancy solution
When it comes to autonomous driving, many people worry about how the vehicle will ensure the safety of the occupants in the vehicle once the system fails and the driver cannot take over. Bosch adopts an ESP and EPS (Electronic Steering Boost). And the intelligent brake booster iBooster backs up each other and is redundant with each other. In the event of an emergency, the vehicle can be braked in complex road conditions to avoid or mitigate accident losses.
