CESA: Continental Innovative Air Supply System CAirs

Online message of Zhongguancun: On June 11, the advantage of the electronic air suspension system is that it can improve the driving comfort and dynamic control. Conforming to this trend, the technology company Continental successfully developed a new solution - Continental Air Supply System (CAirs).

As an integrated system, CAirS greatly simplifies the installation on the vehicle and can be applied to various applications, including simple body height control and a complete integrated solution to realize relevant functions by controlling spring stiffness and damping. CAirs is a closed loop system with a compress Air tank, which makes the system more quiet and efficient. Because of its compact design, lightweight weight and excellent performance of noise and vibration, this integrated air supply system is very suitable for high-end passenger cars and SUVs. It is also an ideal choice for electric and automated vehicles, and will become a key element of air suspension in the future.

Continental's Innovative Air Supply System CAirs: Ideal for Electrified and Automated Vehicles

·CAirS based on closed-loop system is more quiet and efficient

·CAirs can effectively improve vehicle stability and ensure driving comfort

·With its compact size and the advantage of being able to reduce the height of the body at high speed, CAirs can effectively reduce energy consumption

CAirS is an integrated system in Continental's electronic air suspension product family, which can control the entire chassis air suspension system. By integrating the air supply CAirS, the intelligence available in the electronic control unit Software With the high-tech air spring module, Continental Dynamic Control Systems has become the only electronic air suspension system supplier, which can provide comprehensive and high-end chassis solutions.

Vice President and General Manager of Continental Chassis and Safety Business Group in China, Mr. Huo Bin, the head of the Dynamic Control System Division in China, said: "The highly integrated CAirs can ensure the active adjustment of the vehicle's suspension system under different road conditions, effectively improve the vehicle's handling stability, driving comfort, enhance the vehicle's safety during driving, and reduce the vehicle's carbon dioxide emissions. CAirs has provided Chinese vehicle manufacturers with energy conservation and emission reduction programs that meet increasingly stringent emission regulations, and also provided manufacturers with air supply systems that conform to the development trend of electric and automated vehicles. "

Lightweight

According to the target value of Chinese automobile manufacturers to meet the average fuel consumption of enterprises (CAFC), Chinese automobile manufacturers must ensure that the fuel consumption of new passenger vehicles will reach 5 liters/100 kilometers by 2020 and 4 liters/100 kilometers by 2025. Among many current energy saving and emission reduction schemes, vehicle lightweight can achieve this requirement most effectively and quickly. CAirs is a major technical improvement for the current air supply system. Compared with traditional system, compressor, valve block, control unit and motor drive The CAirS with devices/relays, internal pipelines, temperature sensors and connectors integrated into a compact unit can reduce the weight by up to 1.5 kg. With its compact and compact size, CAirS can effectively reduce energy consumption, and the compressor power consumption of CAirS can also be saved by nearly 70%. In addition, air resistance can also be reduced by reducing the body height. If it is applied to SUV models, the carbon dioxide emissions/energy consumption of cars will be reduced by up to 5%.

"Because the hardware part of CAirS is the same in most applications, its functional scope mainly depends on the printed circuit board components and software environment. The flexibility of CAirS enables it to meet the requirements of most user groups through the same technology." Tobias Kummer, the head of Continental Electronic Air Suspension China Customer Center, said.

Electrification

The Medium and Long term Development Plan of the Automotive Industry has set the target of reaching 2 million new energy vehicles by 2020 and 7 million by 2025. The low power consumption requirement of CAirs air supply module stems from its closed-loop design. Open loop air supply system needs to consume a lot of energy when supplying compressed air. With the CAirS module, the air volume and pressure level will be controlled by the intelligent air supply system. Due to low power consumption, CAirS module can quickly reduce the height of electric vehicle body and reduce air resistance. "CAirS is an ideal choice for electric vehicles. The comprehensive power consumption of components in electric vehicles directly determines the endurance. As a key component of the air suspension system, CAirS has no strict requirements on power and low noise." Tobias Kummer explained.

Continental will showcase this new electronic air suspension system solution at the 2019 Consumer Electronics Asia (N5 Pavilion # 5702 and # 5716) in Shanghai.
