Electronic enthusiasts' news: In recent days, the phrase "Houde carries fog, self-improvement does not suck" has been popular in many places, indicating people's helplessness to the hazy weather; travel in this gray environment does exist greatly Inconvenience, whether walking or driving, in the case of extremely low visibility, the most worrying thing about our travel is the safety issue. Based on this, the editor of the electronic enthusiast website has compiled four major technologies to solve this problem for everyone, including automotive LEDs Lighting technology, radar technology, GPS technology and the latest Beidou navigation technology.

Automotive LED lighting technology

Efficient collimated lighting lens: assist LED light source in automotive lighting

Recently, researchers in the Information Photonics Laboratory of the Xi'an Institute of Optics and Fine Mechanics, the Chinese Academy of Sciences have designed a lens for efficient LED collimation illumination, which can focus 80% of the light emitted by the LED into a 5 meter radius cylinder and out of the light source. 200 meters of pavement.

As the fourth-generation lighting source, LED is the key to achieving efficient light output and collimated lighting. The international authoritative magazine in the field of optoelectronics believes that researchers use simple and fast methods to design two non-imaging LED collimating lenses, which is completely different from the complicated iterative software design methods commonly used in existing LED optical designs.

Haze travel artifact: LED products that are maps and flashlights

Boston-based designer Owen Song has designed a new LED application called Light, which is a map and a flashlight.

This concept product combines two pieces of paper, one with a map printed on it, the other with a cover and a power generating device with positive and negative poles in the back. A thin battery and LED lights are wrapped between the two pieces of paper. When you roll the map When the positive and negative poles are connected, the LED lights will glow, so that the map becomes a flashlight.

Radar technology

Application of Radar in Automobile Active Safety System

Automobile safety performance is an important issue in the development of automotive technology. In order to improve the driving safety performance of vehicles, various advanced technologies are applied to automobiles. The following small series introduces the application of automotive radar in new active safety system vehicles, and explains its system structure, working principle and design ideas; I hope it can play a guiding role in the future research and development of active safety performance.

Automobile's active safety technology can prevent accidents from happening, and is increasingly valued by major car companies and consumers. More advanced technologies are also applied to it. The pre-collision safety system and adaptive cruise control system with radar ranging technology as the core have become new targets for active safety systems in recent years.

Pre-Collision Safety System (Pre-Collision Safety System) referred to as PCSS, which is mainly composed of real-time monitoring radar, various sensors, signal processing modules, alarm modules and actuators; the core technology of the system is to use the radar device installed in the front of the vehicle Measure the distance of the dynamic vehicles and obstacles ahead, and feed back the measured vehicle and obstacle information to the system signal processing module (see Figure 1).

The signal processing module integrates the radar feedback information with the various sensor information of the vehicle to calculate the relative distance and relative speed of the vehicle with the PCSS system and the obstacle in front. When the distance and speed cannot meet the minimum safety value preset by the system, the actuator will activate the safety device on the vehicle to assist the driver to control the driving of the vehicle to achieve the goal of active anti-collision. 【Details】

Infineon's automotive radar chip allows cars to see the road ahead

In Europe, car accidents cause approximately 1.7 million injuries and 40,000 deaths each year. The European Union plans to reduce this number by half by 2010, and the application of innovative safety systems to automobiles will help achieve this goal. For example, regardless of visibility, medium and long-range radar systems can reduce the risk of road traffic accidents. After the vehicle is installed with such a safety system, other vehicles and obstacles 20 to 200 meters ahead can be identified.

At present, the radar system is expensive, exceeding 1,000 Euros, and it is difficult to widely put it into commercial use. In addition, the size of these systems is usually 10cm X 20cm, taking up a lot of space in the car fender.

Infineon Technologies will change this situation with a new radar chip. It is expected that mid- and long-range radar systems using this chip will enter the mid-range car market by mid-2010. Using the RXN7740 in the RASIC â„¢ (radar system IC) product family, manufacturers can reduce the size of the radar system by a quarter, while reducing the system cost of wireless RF modules by more than 20%.

Hans Adlkofer, Vice President of Infineon Technologies and General Manager of the Sensor Control Business Division, said: "Radar technology is the key to designing innovative driver assistance systems to avoid traffic accidents. No matter what weather conditions our radar chip (including Foggy, rainy and snowy days) can make the car see the road ahead. It is with this chip that the mid- and long-range radar system will become the standard equipment for mid-level vehicles by 2010. " [details]
