Embodiment

[0041] like figure 1 As shown, the scene-based assisted driving system of this embodiment is composed of a vehicle ECU data acquisition device, a mobile assisted driving terminal, and a cloud intelligent platform. The vehicle ECU data acquisition device is connected to the vehicle fault diagnosis interface, reads the 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 has a built-in The GPS module, wireless communication module and language player modules collect the geographical coordinate data of the vehicle during the driving process, and combine these data with the data collected by the vehicle ECU data collection device through wireless (GPRS / 2G / 3G / Wi-Fi ) network is synchronized to the cloud intelligent platform, and receives the analysis results of the cloud intelligent platform, and assists the driver in driv...

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 realizing a scene-based assisted driving system. Background technique [0002] The existing assisted driving systems are mainly divided into two types: one is used for path navigation; the other is used for driving action prompts. The assisted driving system used for route navigation mainly returns the driving route with the shortest distance to the user according to the topological structure of the map. Real-time traffic conditions are not used as the condition for route selection; the assisted driving system used for driving action prompts reads the vehicle operating condition information by connecting the vehicle ECU data acquisition device with the vehicle fault diagnosis interface, and transmits the vehicle operating condition information to the driver. The behavior analysis terminal conducts analysis, and the driving behavior analysis terminal...
