Abstract

The invention relates to the field of intelligent driving, and provides a driving assistance function calling device and method. The device includes an environment information collection module, a vehicle information collection module, a signal processing module, a storage module, a comparison module and a function calling module. The device is capable of collecting information of the surroundingenvironment and information of vehicles, and comparing with preset application scenarios to determine a current application scenario, calling a driving assistance function suitable for the current application scenario and assisting the driver in driving. The driving assistance function calling device and method combine the driving assistance function that can be only used in a limited scenario through a calling relation, and reuses a volume production function so as to effectively improve the reliability of the automatic driving system and expand the application range of the driving assistancesystem.

Description

technical field [0001] The invention relates to the field of intelligent driving, in particular to a device and method for invoking a driving assistance function. Background technique [0002] Autonomous driving technology is currently a hot spot in the automotive industry. According to SAE's automatic driving classification, it is currently divided into five automatic driving classifications, L1-L5. Among them, L1-L2 autonomous driving is still essentially a driver assistance system (ADAS), and L3 Level-1 autonomous driving can be called a quasi-autonomous driving system, and L4-L5 level autonomous driving can be considered a truly meaningful autonomous driving system. [0003] At present, global automakers are able to complete mass production, none of which exceeds L3 autonomous driving. In essence, it is still a function stack of multiple driver assistance systems, with high reliability but limited application range in driving scenarios. The purpose of the driver assista...
