¡¡¡¡Code words

¡¡¡¡

¡¡¡¡The UK began using umbrellas only in the 18th century. The Bernas umbrella was once a special item for women, which expressed women¡¯s attitude towards love. Holding the umbrella upright means being faithful to love; holding the open umbrella in the left hand means holding the umbrella tightly. Slowly shaking the umbrella means lack of confidence or distrust; leaning the umbrella on the right shoulder means not wanting to see you again.

¡¡¡¡

¡¡¡¡Social significance

¡¡¡¡

¡¡¡¡In ancient China, umbrellas symbolized power for emperors, generals, and dignitaries, as clearly recorded in the ¡°Book of Jin¡± and ¡°Yufuzhi¡± in Zuo Zhuan. The records show a strict hierarchy associated with their use. The materials, colors, and sizes of umbrellas are like the black gauze on the head and the court dress on the body, which also distinguish the official positions. For example, in the Han Dynasty, it was stipulated that the nine ministers and three officials who ate more than 2,000 stones of millet used black. The officials who were not allowed to wear black clothes were all allowed to wear blue. Therefore, in ancient times, the sedan chairs or cars that the emperors or high officials rode on when they went on tours all had umbrella covers to show that they ¡°shaded the people.¡± Therefore, this kind of umbrella is also called ¡°cool umbrella¡±, ¡°Luo umbrella¡±, ¡°all people¡¯s umbrella¡±, and ¡°Huagai¡± in written language.

　　Expected functional safety solves the problems of insufficient related functions, performance limitations, and human misuse after the complexity of system functions increases. For example, if the driver does not operate the intelligent driving function correctly, the perception algorithm function is limited and cannot accurately identify the faded lane line, or the perception identifies the truck in front as blue daytime, this will bring fatal problems.

　　

　　At present, the ADAS system has not yet achieved a good implementation combination with expected functional safety, but according to my observation, some companies are also paying attention to this aspect and starting to make some expected functional safety supervision mechanisms. Expected functional safety is more targeted at high-level ADAS systems (L3 and above), because the system is more complex and needs to pay more attention to expected functional safety.

　　

　　Information security, this direction involves more and wider areas than the first two, involving data communication security between vehicles and within the vehicle. At present, I personally have not been exposed to information security in ADAS, and I hope that other experts in information security can talk about it together.
