Extensible intelligent driving assistance system

Abstract

The invention discloses an extensible intelligent driving assistance system. The extensible intelligent driving assistance system comprises an extensible hardware structure and an extensible softwarestructure which is matched with the extensible hardware structure; the extensible hardware structure comprises a processor, a connector, a cascade circuit and at least one sensor; the connector is directly connected with the sensor by using an Ethernet twisted pair and is in transit connection with the sensor by using the cascade circuit; the extensible software structure is embedded in the processor; and the extensible software structure comprises a time synchronization sensor access module, an interface adapting module, a perception algorithm module and a functional logic module. Through adoption of the mode, the extensible intelligent driving assistance system has the advantages that the hardware and the software of the intelligent driving system realize sufficient extendibility, the extensible intelligent driving assistance system can be flexibly applicable to vehicle models with high, medium and low configurations, the system development efficiency is enhanced, the system development quality is improved, the development cost is reduced, and the time-to-market is reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle intelligent driving, in particular to an expandable intelligent driving assistance system. Background technique [0002] According to the definition of the International Automaton Association, the intelligent driving system of a car is divided into six levels from 0 to 5 according to the degree of intelligence. Level 0 means manual driving that relies entirely on the driver without intelligence, and level 5 means that the car does not need a driver and can run fully automatically. Considering the cost, technology and social development, the intelligent driving system follows the law of evolution from low-level to high-level, and develops towards a safer, smarter, and more efficient direction. Active safety systems such as anti-lock braking systems and handling stability systems are generally used in level 0 autonomous driving vehicles to improve driving safety and reduce accidents. Different fro...

Problems solved by technology

The problem with this kind of system is that when the system needs to be upgraded from level 2 to level 3 or higher, or from low-end models to high-end models, due to the addition of sensors or functional modules, the original Some systems are redesigned (for example, we originally developed a level 2 autopilot system using millimeter-wave radar and image sensors. When we want to develop a level 3 autopilot system, we need to add a lidar sensor. At this time, the original Both software and hardware have to be redesigned), resulting in low system development cycle, management, cost and efficiency
