What is the model of China s first driverless car and how does it perform? How does it compare to th

China's first driverless car was successfully developed in Changchun, and the basic principle of autonomous driving of the car is humanoid driving. The control components of this sedan have been miniaturized, and the autonomous driving controller is not visible in the cabin, maintaining the original style of the cabin.

It is reported that the autonomous driving system developed in the United States has a maximum stable speed of 100 kilometers per hour on highways and 120 kilometers per hour in Germany. The maximum stable speed of self-driving cars successfully developed in China is 130 kilometers per hour, and the maximum peak speed is 170 kilometers per hour, which has reached the world's advanced level. Some experts predict that after 2010, high-end cars will be equipped with automotive active safety systems with autonomous driving systems as the core.

How driverless cars work.

The in-vehicle environmental recognition system recognizes road conditions and measures the distance and speed of the vehicle in front of it, which is equivalent to the driver's eyes. Then, the vehicle-mounted main control computer and the corresponding path planning software decide whether to advance along the road or change lanes to prepare for overtaking according to the road information provided by computer vision, the situation of the vehicle in front of the vehicle and its own driving state, which is equivalent to the driver's brain; Then, according to the path to be tracked and the driving dynamics of the car, the automatic driving control software sends action instructions to the steering wheel controller, accelerator controller and brake controller, and controls the car to move forward according to the planned path, playing the role of the driver's hands and feet.

Lexus, Audi Q3, Volvo XC90, Tesla Model X, refer to these cars.

Lexus ES, Audi Q3, Chrysler, Tesla Model X, Volvo XC90, these driverless cars are all technologically advanced.

Tesla, Lexus, Audi, Subaru, Ford, these cars are of good quality and have advanced features.

Lexus ES, Audi Q3, Chrysler, Tesla, Volvo, these are very good.

Volvo, Infiniti, Great Wall, Ford, BMW, Honda, these cars are very good, and the quality of the cars is passable.

Now there is, it's just not approved to hit the road.

Artificial intelligence technology is the basis for the development of unmanned driving, and there are a large number of applications in the system, which can be said to be inseparable. It is mainly divided into three parts: the environment perception module, the decision planning module and the control execution module.

1) Environment perception module.

As the most important part of unmanned driving, its development often determines the degree of application of unmanned driving. The most important thing for unmanned driving is to perceive the surrounding environment information in real time, so as to obtain the information of the number key in time, which is completed by sensors, such as cameras, lidars, millimeter-wave radars, and ultrasonic sensors [4], whether in a familiar environment or a new environment, the car can do clustering processing according to these sensor data, and use various algorithms to detect lane lines or markers around, and analyze the manuscript code through the analysis module in the system. The only drawback is that the existing self-perception technology cannot achieve high accuracy, and can only obtain body status information and location through GPS for navigation.

2) Decision planning module.

Based on the real-time road network information, traffic environment information, and driving status transmitted by the sensors, the autonomous driving system generates decisions through analysis, such as safe and fast automatic driving decisions that comply with traffic rules (including sudden abnormal conditions) [5]. This is related to the recent emergence of 5G technology, because there will be a huge amount of real-time data transmission and acquisition on the road of unmanned driving technology, the original network technology has been unable to meet this demand, 5G is reasonably applied, which not only ensures the safety of driving, but also accelerates the development of the technology.

3) Control the execution module.

According to the planned driving trajectory, as well as the current driving position, attitude and speed, control commands for the accelerator, brake, steering wheel and gear lever are generated. Traditional control methods include PID control, sliding mode control, fuzzy control, and model control [6]. For example, the low-level car cruise control and the current unmanned driving are the concrete embodiment of this module control.

1. In 1992, the National University of Defense Technology successfully developed China's first driverless car in the true sense.

The first urban driverless car was successfully developed at Shanghai Jiao Tong University.

Features of driverless cars.

1. Use on-board sensors to perceive the surrounding environment of the vehicle, and control the steering and speed of the vehicle according to the road, vehicle location and obstacle information obtained by perception, so that the vehicle can drive on the road safely and reliably.

2. It integrates many technologies such as automatic control, system integration and sliding rough structure, artificial intelligence, visual computing, etc., and is the product of the high development of computer science, pattern recognition and intelligent control technology.

1. Save thousands of lives every year.

According to a set of data released by the World Health Organization, traffic accidents currently kill an average of about 1.24 million people worldwide each year, and this number is expected to increase to 2.2 million by 2030. In the United States alone, about 10,000 people die in traffic accidents each year.

And driverless cars, if widespread, could save millions of lives, as they would dramatically reduce traffic accidents. According to another study, if 90 percent of the cars on the U.S. were driverless, the number of traffic accidents would fall from 6 million to 1.3 million each year, and the number of fatalities would fall from 10,000 to 10,000.

Over the past six years, Google's self-driving cars have traveled more than 200 miles, and so far, there have been only 16 very minor traffic accidents, and the "culprit" in each accident was not the Google driverless car. 、

2. Carbon dioxide emissions have been greatly reduced.

In addition to saving lives, driverless cars may also be able to help protect the planet. This is because autonomous vehicles can optimize vehicle acceleration, braking, and speed adjustment, and make rational use of kinetic energy systems, which can improve fuel efficiency and reduce CO2 emissions. According to a McKinsey report, driverless cars can help reduce carbon dioxide emissions from vehicles by 300 million tons per year.

What is the concept of this number? That's half of the total CO2 emitted by the global commercial aircraft sector each year.

3. People will no longer own private cars.

Industry analysts expect that driverless cars will be able to dramatically change people's travel habits, "inducing" them to abandon their driving in favor of robo-taxis.

According to a study by the University of Michigan's Transportation Research Institute, car ownership in the U.S. would drop by 43 percent if driverless cars become widespread, in part because it is cheaper to use driverless car rideshare services than to drive yourself, which can reduce the cost per mile by 80 percent.

4. Solve the problem of traffic congestion.

Driverless cars can not only help reduce car accidents, but they can also help to significantly reduce traffic congestion.

According to a study from KPMG, driverless cars are capable of increasing the capacity of cars on highways by a factor of five. Sebation Thrun, a computer scientist at Stanford University and a former member of Google's self-driving car team, said that once driverless cars become mainstream, only 30 percent of the vehicles currently on the road will be needed.

The development of technology, the convenience of artificial intelligence.
