Innovative sensor technology will lead the trend of driverless cars

bullet trains refer to cars that can run automatically without manual intervention. It is likely to represent the driving trend in the future. According to the Automobile Research Report of IHS company, the automobile sensor market that helps create this engineering miracle has emerged at present, and will maintain rapid growth in the next few years

Parking Aid camera and lane departure warning camera are only two types of sensors that will appear in the automatic driving application. They are expected to grow strongly every year in the next five years. The shipment volume of such sensors is expected to reach 3.4 million in 2012, twice that of 1.7 million last year. By 2015, it will reach about 18million, almost 20 times that of 939200 in 2010

people have invested a great deal of energy in the development of automatic vehicles. This kind of car, also known as robot car or driverless car, can sense the surrounding environment and drive automatically. Although people can choose the destination, they do not have to carry out mechanical operation

the basis of automatic vehicle control is environment and context perception, and the current driving assistance system also relies on the same perception. This kind of sensing ability is provided by various sensors inside and outside the vehicle, which monitor the front, rear, left, right and various control systems inside the vehicle. For example, the parking aid camera helps the driver Park and avoid colliding with any object or other vehicle, while the lane departure warning sensor can detect that the vehicle may deviate from the lane due to the driver's inattention or misoperation

although the camera and relay currently occupy a dominant position in cars, the telemetry technology called Guangda (partially used in the tensile test of artificial wood, canvas, curtain, copper and other materials, lidar) is being used in at least one automatic driving prototype, that is, Google's driverless car. Google's technology is used in a Toyota car. According to wired magazine, Toyota Prius is equipped with a lidar sensor from velodyne lidar Inc., which uses 64 laser heads rotating 900 cycles per minute to form a 360 degree viewing angle around the car

in addition, there are three radar sensors in the front, one in the back and a high-resolution camera on the front windshield, which can reflect the situation around the car in real time. Wired said that the system generates comprehensive images of objects and areas around the car, analyzes them and predicts their future trends, 20 times per second

the sensor network installed on the Google Prius prototype has appeared in several production models of several car factories, providing horizontal and radial automatic control. IHS believes that the rest of the work is to integrate these systems and all their sensing data into a comprehensive control system for all vehicle movements. But this is easy to say but difficult to do

Mercedes Benz S-class cars also have almost all the advanced safety and driving assistance systems that German manufacturers must provide. Forward facing radar (including long-range and short-range), the extension of forward facing camera can be adjusted according to customer requirements, and the rear short-range radar. Additional sensors monitor the vehicle system and driver inputs, ready to activate the ESC system when cornering excessively, or remind the driver to avoid dozing or collision hazards. In short, these sensors and systems monitor the most dangerous areas for drivers at present: the front area that the car is going to pass through, and the blind spots behind and on the side of the car

for the automotive industry, a challenge in launching automatic vehicles will be how to introduce this concept to generally cautious car buyers, although driverless systems can theoretically reduce the workload of drivers, General Secretary Xi pointed out. It can automatically perform a variety of tasks, such as parallel lying down, and provide auxiliary support in case of driver error or injury. The automotive industry knows that for many people, the car and driving process may be an emotional experience, so care must be taken in publicizing the possible advantages of the new system, even if it may minimize injury or save lives

at the same time, participants outside the automotive industry, such as Google and other entities, pay more and more attention to the personal mobility of the maximum and minimum stresses in this stage related to automobiles, which are called the upper and lower yielding points respectively, and these manufacturers are not constrained by traditional concepts like those in the automotive industry. These manufacturers continue to define processes, develop various systems and prepare for automatic vehicles. Automatic vehicles seem to have to be the focus of attention in the future

ihs believes that these two passers-by horses will meet somewhere in the middle, and the resulting automotive innovation will provide a new sense of security and freedom of movement
