01 What is a skateboard chassis? The so-called skateboard chassis integrates the battery, electric transmission system, suspension, brakes and other components on the chassis in advance to achieve separation of the body and chassis and decoupling the design. Based on this type of platform, car companies can significantly reduce early R&D and testing costs, while quickly responding to market demand to create different models. Especially in the era of driverless driving, the layout of the car is no longer centered on driving, but will focus on space attributes. The skateboard-type chassis can provide more possibilities for the development of the upper cabin. As shown in the picture above, of course when we look at the skateboard chassis, we should not be framed by the first impression of "Oh, it is a non-load-bearing body" when we come up. There were no electric cars back then, so there were no battery packs worth hundreds of kilograms, no steering-by-wire system that could eliminate the steering column, and no brake-by-wire system.

01 Control-by-wire technology Cognitive control-by-wire technology (XbyWire) converts the driver's operating actions through sensors into electrical signals to achieve transmission control, replacing traditional mechanical systems or hydraulic systems, and the electrical signals directly control the actuators to achieve control The purpose and basic principle are shown in Figure 1. This technology originates from the FlybyWire aircraft launched by the National Aeronautics and Space Administration (NASA) in 1972. Among them, "X" is like the unknown number in a mathematical equation, representing various components and related operations in the car that are traditionally controlled mechanically or hydraulically.

Just like human walking, self-driving cars also need to have the ability to think independently and make judgments and decisions about the traffic environment in order to complete the travel process. With the improvement of advanced assisted driving system technology, the safety of drivers driving cars continues to improve, and the degree of driver participation in driving decision-making is gradually reduced. Autonomous driving is getting closer and closer to us. Self-driving cars, also known as driverless cars, are essentially highly intelligent robots that can complete travel behaviors with only driver assistance or without driver operation at all. Autonomous driving is mainly realized through the perception layer, decision-making layer and execution layer. As an automated vehicle, autonomous vehicles can use additional radar (millimetre-wave radar, lidar), vehicle cameras, and global navigation satellite systems (G

On July 16, China Grand Automobile's closing price was lower than 1 yuan for 19 consecutive days, and the closing price on that day was 0.87 yuan. Even if it rose to the limit the next day, the stock price would be difficult to return to 1 yuan. At this point, China Grand Automobile triggered the delisting requirement of "the stock price is less than 1 yuan for 20 consecutive trading days". Therefore, delisting was locked in advance and became the stock with the largest market value at the time of delisting in the history of A-shares, with 72 A huge amount of billions. However, according to the financial report, China Grand Automobile's revenue in 2023 will still reach 137.998 billion yuan, with total vehicle sales of 713,000 vehicles. It is still the largest automobile dealership group in China in total passenger vehicle sales and second in revenue scale. In the capital market, after backdooring Metro Pharmaceuticals to go public in 2015, China Grand Automobile’s share price soared to a maximum of 32.12 yuan per share, and its market value once exceeded 100 billion.

01E-GAS safety architecture concept Automotive functional safety aims to control the risk of personal harm caused by the failure of electronic and electrical systems within a reasonable range. The following figure is a common electronic and electrical system hardware composition diagram. The components of an electronic and electrical system, in addition to the visible hardware in the figure, also include software that is not visible in the figure. Figure 1 Commonly used electronic and electrical hardware systems Failures of electronic and electrical systems include both systemic failures caused by software and hardware design errors and failures caused by random hardware failures. According to the system architecture, various safety mechanisms need to be designed to prevent and detect functional failures, and to avoid or reduce the harm when a failure occurs. This requires a strong functional safety software architecture to manage and control these safety mechanisms and reduce the overall risk of functional safety.
