Abstract: In order to meet the requirements of vehicle safety in the complex application scenarios of extended-range all-terrain vehicles, safety control technology is studied from three core components: battery, motor and electric control unit. According to the different impact of vehicle safety and the different response speed, the key level of components and the fault handling authority are divided. Through the mutual cooperation of the system and components, the layered control method is adopted to make the vehicle meet the safety needs. Finally, the real vehicle safety test is carried out, and the test results show that the safety control technology used for the three core components can effectively ensure the safety of drivers and vehicles.
