[0002] A car is a non-rail-borne vehicle that is powered by power and has four or more wheels. It is mainly used to carry people or goods and perform special operations. Cars can be classified into different categories based on various standards such as purpose, power source, and vehicle size. For example, cars can be divided into passenger cars and commercial vehicles based on purpose; cars can be divided into fuel vehicles and new energy vehicles (including pure electric vehicles, plug-in hybrid vehicles, fuel cell vehicles, etc.) based on power source; cars can be divided into microcars, small cars, compact cars, medium-sized cars, large cars, etc. based on vehicle size. The braking system is very important for vehicles.
