Hello Dr. Tech, I am going to celebrate the New Year, and the air is filled with a relaxed taste. I even feel that the days of waiting for a holiday are better than the Spring Festival holiday. I wonder if you have this feeling.
This article refers to the address: http://
I have been so busy, in fact, I want to ask, read so many columns, and understand all kinds of car black technology and fresh gadgets. If you let you rate a leaderboard, which one do you think will be on the list?
——Cuihua is counting the number of days in the calendar
[Dr. Tech]
Hello, Cuihua, I can only partially agree with your point of view. After all, even if I am getting closer to the Spring Festival, I still often work overtime, and I feel completely relaxed.
However, one year has passed, it is indeed necessary to make a small summary (this should have been done in January, but CES and the North American Auto Show are really eye-catching...). If you let me comment on Top5, I think it should be these...
After waiting for 10 years, the hybrid finally got the price of cabbage.
From the Prius (participation, pictures, inquiry) into China, to the hybrid system, Toyota has let domestic consumers wait for 10 years. A tank of oil runs 900 kilometers, the battery is maintenance-free for life, and the fuel consumption per 100 kilometers is less than 5 liters. Hybrid power can sell 8 million vehicles worldwide. The reason is quite sufficient. However, Toyota has always been subject to high prices in the country, and it is not a good name.
After ten years of preparation, Toyota finally realized the nickel-hydrogen battery, PCU, and Toyota's core "black technology" - planetary gear power distribution device, and the price of Toyota Twin Engine finally closed to the gasoline car. The starting price of the version of Corolla (participation, picture, inquiry) and Lei Ling (participation, picture, inquiry) are only 139,800 yuan. Of course, according to Toyota, hybrids are not only cost-effective, but the domestic version is also superior in performance compared to the third-generation Prius hybrid system, such as the latest battery cooling system and a more efficient control unit (weight reduction). 15%, volume reduction of 35%, energy loss reduced by 20%).
However, in the face of more and more cities now encouraging electric vehicles through policy measures such as limit restrictions, the biggest problem facing hybrid power has also shifted from the market level to the policy level. This domestic, is it a bit late?
Left hand, right hand, slow motion, new posture, learn
For gesture control, I believe that everyone has seen a lot in various concept cars, but it is still the same sentence - "Showing black technology without mass production, it is rogue", even if this technology is played on the concept car. Nothing is too big for consumers.
Therefore, as the first model to mass-produce the gesture control technology, the new BMW 7 Series (matching, picture, inquiry) listed last year is worth mentioning. The gesture control function of the BMW 7 Series is realized by the infrared 3D camera above the center console. The camera continuously captures the gestures of the driver or the passengers in the passengers. The infrared method makes it unnecessary to worry about the system being affected by external light, even in the dark. The effective recognition area of ​​the gesture control is set between the front armrest box, the transmission lever and the upper edge of the iDrive screen, so as to prevent the misoperation of the front and rear passengers as much as possible.
Of course, due to technical conditions, the current gesture control can only recognize some simple actions, which is not necessarily a better way of human-computer interaction than voice. However, adding a new way of communicating in the car is still a major step forward. Local lords, don’t you come to feel it?
Just talk about the technical public emission fraud to remind us what
If you want to say that the most exciting and tortuous events in the car circle last year, it is absolutely not a mass discharge door. I believe that people who pay a little attention to the car circle will not be unfamiliar with this. Here, Dr. Tech is not talking about topics such as integrity, responsibility or the future of the company, but from a technical point of view.
Let's review the basic principles of mass emission fraud: the cheat software can judge whether it is under test according to the engine operation. If it is being detected, start the exhaust gas treatment device to ensure the discharge is up to standard, otherwise the exhaust gas treatment device will be turned off to achieve lower fuel consumption. . There are at least a few of the effects of mass emissions fraud on automotive technology. On the one hand, the public needs to use cheat software to ensure low fuel consumption in consumer use at the expense of emissions. This at least indicates that the existing diesel engine technology is still difficult to achieve a good balance between fuel consumption and emissions, which will have a profound impact on the clean diesel technology route that Europe has long pursued.
On the other hand, today, electronic technology has become an important part of the operation of automobiles. How to strengthen the supervision and protection of software has become a new topic in the automotive industry. For the government, it is necessary to judge similar cheating behaviors of car companies. For car companies, it is necessary to avoid attacks against electronic control systems such as hacking. Last year, car companies have specifically recalled vehicles for the risk of hacking. This situation is likely to be more serious in the future.
There is finally someone in the tears to do something for navigation.
Remember the first issue of Dr. Tech? Why car navigation is not as good as a mobile phone. The update is slow, the data is old, and the route planning is not accurate... In fact, the manufacturers also know, but there seems to be lack of motivation for changing the status quo. This is really fascinating when you think about it. Say good "Customer is God"?
So, when someone finally came to answer the question and did something, it was still very moving. Not long ago, Goldtech launched the Internet car navigation products. This in-vehicle navigation not only optimizes the interface and function for driving scenes, but also displays real-time traffic conditions and avoids congestion.
Unlike the light solutions of carlife and carplay, the high-definition solution is a self-contained car product that can read the vehicle data and achieve deeper integration with the car itself, resulting in better navigation. Experience. Imagine that you won't miss the intersection because of a sudden phone call, and you can achieve a precise positioning far beyond the phone. In the long run, this is an inevitable trend, but the first person to eat crabs will also face greater challenges from the market and industry.
Anyway, we also have autonomous cars.
When it comes to self-driving cars, most people think of Google. In fact, in a sense, it is Google that makes the discussion of autonomous driving cars a fashion, and also allows the black technology trials of autopilots made by many car companies to come to the public.
Solar Charge Controllers manage voltage and current from solar panels to batteries, preventing overcharging and optimizing battery life for reliable energy storage.
Usage:
Solar charge controllers are used in off-grid solar power systems, such as solar street lights, solar water pumps, RVs, boats, and remote cabins. They are also used in grid-tied solar power systems with battery backup to manage the flow of electricity between the solar panels, battery, and grid.
Working principle:
Solar charge controllers work by monitoring the voltage and current from the solar panels and adjusting the charging parameters to maintain the battery at the optimal voltage level. When the battery is fully charged, the charge controller will reduce the charging current to prevent overcharging. Similarly, when the battery is low, the charge controller will increase the charging current to ensure the battery is properly charged.
Purpose:
The main purpose of a solar charge controller is to protect the battery from overcharging and discharging, which can reduce its lifespan and performance. By regulating the flow of electricity from the solar panels to the battery, the charge controller ensures that the battery is charged efficiently and safely. Additionally, solar charge controllers can also provide information on the performance of the solar power system, such as the amount of energy generated and stored in the battery.
