· Drones and drones have arrived, will the spring of electric cars be far behind?


Recently, the word "no one" appeared frequently in the news media. At MWC2015, Mercedes-Benz launched a driverless car; in the news of the previous few days, Baidu and the Ministry of Communications jointly developed a driverless car; the White House Invaded by the drone, Wang Feng proposed Zhang Ziyi, and sent the ring with the drone. The courier company uses the drone to send the courier...
Flying in the sky, the sudden running on the ground is uninhabited. Why is this? What impact does unmannedness have on new energy vehicles, especially electric vehicles?
1. How did the drone rise?
The history of drones is actually very long. The bombing of London's V1 missiles (the prototype of cruise missiles) during World War II can actually be regarded as a drone.
After the Second World War, the use of drones in the military was also very extensive. In 1964, the Chinese mainland had laid the US unmanned reconnaissance aircraft. After the 1990s, drones were more omnipotent. The Gulf War was a drone that lured the Iraqi air defense radar to start; the Afghan anti-terrorism was a drone that directly fired weapons and beheaded the Taliban and al-Qaeda leaders.
However, although the technology of military drones has been developing for a long time, civilian drones have always been rare, and there are even fewer drones that individuals can afford. This is mainly because the drones are expensive and technically complex, and are only available for military use and professional applications at no cost.
The emergence of smartphones and electric cars has changed everything.
When Apple released the iPhone in 2007, the smartphone revolution began, and people around the world switched to powerful smartphones.
The rise of smart phones has led to the rise of the microelectronics industry chain, cameras, microprocessors, memory, flash memory, and prices are falling rapidly every year.
These components are precisely the core components required by drones. The result of the rise of smartphones is that the cost of drones has rapidly decreased, and the price has dropped rapidly. The drones have flown from the professional military field to the homes of ordinary people.
In addition to the price reduction of microelectronic components, the battery factor can not be ignored. With the development of smart phones and electric vehicles, the production scale of lithium batteries has also expanded rapidly, especially the high-rate discharge power lithium batteries for electric vehicles have developed rapidly.
The development of power batteries has made electric drones possible, and battery-plus motors are much cheaper than micro-engines with precise construction and limited life.
At present, popular civilian drones are mainly helicopter-like quadcopters. The principle of the quadcopter is very simple. The flight control is easy because of the advancement of microelectronics. The price is relatively cheaper than the previous price.
The toy-level four-axis aircraft is only about 200 yuan, the professional level can send the ring, can be aerial photography, and the price of invading the White House is only a few thousand to 1,000. Far cheaper than a car, almost everyone buys it.
Therefore, the cheap civilian drone is actually the dividend of the development of smart phones, and the rise of smart phones has contributed to the development of civilian drones.
2. How did the driverless car appear?
The car was originally a purely mechanical thing, and the electronic components of the instrumentation were few. However, with the development of technology, there are more and more electronic devices in automobiles. The development of automobiles in recent decades is actually the development of automobiles to electronic.
The earliest electronic intelligent device is ABS. The simple computer controls the brake according to the data transmitted by the sensor to avoid the car getting out of control.
Later, the throttle was also telegraphed. When people step on the throttle, they control the electronic signal instead of directly controlling the intake air. The onboard computer controls the throttle through the motor based on the electronic signal.
Later, the steering wheel is also telex. The person turning the steering wheel does not directly control the front wheel steering, but the computer interprets the person's movements to turn the direction (Infiniti).
At this point, the car became a fully electronically controlled device, theoretically, canceling the steering wheel, throttle and brakes. Give the driver a mouse, slide the control direction, left button to control the throttle, right button to control the brakes, and the driver can drive like a racing game.
All the car controls use electronic signals, which lays the foundation for unmanned driving. As long as there is enough artificial intelligence, it can make accurate judgments based on the road conditions and sensor feedback data. The car can be without the driver. The core problem becomes the ability to collect enough information from sensors (including cameras), the processing of sensor data (including image recognition), and the judgment made by artificial intelligence. These things depend on the advancement of hardware and software technology, and the computing power of the hardware reaches a certain level. The detection capability and resolution of the sensor reach a certain height, and the software level of the artificial intelligence reaches a certain height, which will naturally occur.
Google is unmanned and actually acquired a small company. When there is a powerful processor on the market, a camera that is clear enough to detect a laser radar far enough away, it takes only a few days to write an artificial intelligence program. Unmanned driving is a matter of course.
Third, behind the rise of drones and driverless cars, we have seen the rise of drones and driverless cars. It is easy to see that their emergence and rise are the result of advances in electronic technology.
Behind this is an old law in the IT industry (proposed in 1965, in the IT industry has been counted as a stone age) - Moore's Law. This law was proposed by Gordon Moore, one of Intel's founders. The content is: When the price is constant, the number of components that can be accommodated on the integrated circuit will double every 18-24 months, and the performance will be doubled. In other words, the performance of computers that can be bought for every dollar will more than double every 18-24 months.
Both the drone and the unmanned core hardware are microprocessors. Only when the technology advances to a certain extent, when the microprocessor can come out with complicated data, drones and driverless cars are likely to appear.
The core of various sensors is also a microprocessor. The camera requires CMOS and ISP chips. Lidar needs to transmit receivers and DSP processing chips, as well as GPS chips and barometers.
These things are all based on integrated circuits made of transistors, which are in accordance with Moore's Law, doubling every 18-24 months, or the same price performance improvement, or the same performance price reduction. In fact, if the missile or aircraft navigation system and the automatic driving system are counted as unmanned, it should be said that drone has appeared very early. However, driverless cars and drones can appear in our lives, so that we may be able to afford them, which is the result of the continuous price reduction of electronic components under Moore's Law. An ancient law in the IT industry has created today's drones and driverless cars.
Fourth, the spring of electric cars will be far behind?
When we talked about driverless cars, we talked about the electronicization of cars in recent decades. The ultimate goal of automotive electronics is the driverless electric car. Compared with fuel vehicles, electric vehicles use motors and batteries to replace the engine and gearbox and fuel tank. This means that the electric vehicle is more convenient to use electronic control, unmanned, and more intelligent. The core part of the electric vehicle includes the battery, the motor, and the electric control, and this electronic control part is also in accordance with Moore's Law. That is to say, the electric control part of the electric vehicle will become cheaper and cheaper in the future.
Motors and battery packs also need control chips or monitoring sensors. They also comply with Moore's Law. Although the amplitude is not so large, the motor and battery will gradually reduce prices. Electric vehicles also involve charging problems. Charging also requires control of the chip. The control chip also conforms to Moore's Law.
The rise of drones and driverlessness indicates that advances in the microelectronics industry have made civilians such as unmanned. The reduction in the cost of electric vehicles and the increase in penetration rate also depend on the advancement of microelectronics technology.
