Embodiment

[0041] Such as figure 1 As shown, the scene-based driving assistance system of this embodiment is composed of a vehicle ECU data acquisition device, a mobile driving assistance terminal, and a cloud intelligent platform. The vehicle ECU data acquisition device is connected with the vehicle fault diagnosis interface, reads vehicle operating condition data and vehicle performance parameter data, and transmits the read data to the mobile assisted driving terminal through the Bluetooth / Wi-Fi network; the mobile assisted driving terminal is built-in GPS module, wireless communication module and language playback module collect the geographic coordinate data of the vehicle during the driving process, and combine these data with the data collected by the vehicle ECU data acquisition device through wireless (GPRS / 2G / 3G / Wi-Fi) ) The network is synchronized to the cloud intelligence platform, and the analysis results of the cloud intelligence platform are received to assist the driver in ...

Abstract

The invention discloses a scene-based driver assistant system realizing method, which comprises the following steps: S1, vehicle condition data and vehicle performance data are acquired through a vehicle ECU (electronic control unit) data acquisition device and the acquired data is transmitted to a mobile driver assistant terminal via a wireless network; S2, geographic coordinate data of a vehicle is acquired through the mobile driver assistant terminal during driving, and is synchronized, together with the data acquired in the S1, to a cloud intelligent platform via the wireless network; and S3, the cloud intelligent platform analyzes out information required for driving assistance from mass data by virtue of a big data analytical algorithm. The realizing method is scientific and effective, takes mass data about historical driving journey as a journey route selection reference frame, and effectively meets the requirement of a driver for route selection. Meanwhile, the method is highly accurate, can accurately identify different driving scenes, accurately judges next driving scene for the vehicle, and correctly directs the driver to do proper driving action.

Description

Technical field [0001] The present invention relates to the technical field of assisted driving, in particular to a method for implementing a scene-based assisted driving system. Background technique [0002] The existing driving assistance systems are mainly divided into two types: one is used for route navigation; the other is used for driving action prompts. The driving assistance system used for route navigation mainly returns to the user the shortest driving route based on the topological structure of the map. This navigation method is a static navigation. The route selection does not refer to other people’s historical itinerary records. The real-time traffic condition is not used as the condition of route selection; the driving assistance system for driving action prompts reads the vehicle working condition information by connecting the vehicle ECU data acquisition device with the vehicle fault diagnosis interface, and transmits the vehicle working condition information to ...
