Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a drive system of an electric passenger vehicle and a drive control method thereof. Background technique [0002] With the development of society and the rapid expansion of cities, the transportation system of most cities is under tremendous pressure. Due to dense population and tight resources in large and medium-sized cities, people have higher and higher requirements for the environment. However, a large number of fuel buses will Huge emissions of pollution and noise are generated, affecting the air quality of the entire city. In small cities, private cars and subways are not well-developed, resulting in more serious dependence on urban buses, and the environment is also under greater pressure. Therefore, buses play an irreplaceable role in the urban transportation system. With the increasing awareness of environmental protection in recent years, the governments of various co...
