Background: In recent years, with the development of economy and technology, the number of
car ownership and road mileage has been gradually increased. A series of problems which the traditional
car cannot solve got increasingly prominent. Automotive intelligent technology is gradually being
applied, and the technology makes the car easier to operate, and safer to drive.
Objective: To provide an overview of recent driverless cars and introduce its basic technologies, respective
characteristics and developments.
Method: This paper reviews various representative patents related to driverless car technologies.
Results: The development of driverless car technology and related patents is briefly reviewed. Five basic
technologies about driverless car are concluded. The main problems in its development are analyzed, the
development trend is foreseen, and the current and future developments of driverless car are discussed.
Conclusion: Driverless car has important practical significance, and plays an important role in promoting the
technology innovation in automobile industry. Further improvements are needed in the aspects of regulation,
intelligence and security of the driverless car. More patents on driverless car should be invented.
