Embodiment Construction

[0024] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below with reference to the accompanying drawings and through specific embodiments.

[0025] like figure 1 As shown, the present invention provides a driving assistance method based on a vehicle-mounted ad hoc network, the method comprising the following steps:

[0026] 1) During the driving process of the vehicle, the front road image is captured by the camera, and the front road image captured by the camera is transmitted to the road image area extraction network to obtain the road area, and then the image containing only the road area is transmitted to the road type recognition network for classification. identify μ;

[0027] 2) Use the mesh vehicle-mounted ad hoc network device VANET to send the detailed information of the current driving road (including location and road adhesion coefficient) to surrounding vehicles, and update the road ...

Abstract

A driving assistance method based on a vehicle-mounted ad hoc network is characterized in that vehicles in a certain area detect road conditions, the road conditions are sent to surrounding vehicles through a VANET (vehicle-mounted ad hoc network), obtained road adhesion coefficients are updated to a cloud end, and the vehicles avoid or decelerate according to road information. Comprising the following steps: S1) acquiring a road adhesion coefficient; S2) transmitting road information; S3) calculating a safe distance; S4) warning by a vehicle-mounted terminal;

Description

technical field [0001] The invention relates to the field of vehicle networking, and more particularly, to a driving assistance method based on a vehicle-mounted ad hoc network. Background technique [0002] In recent years, due to the increase in the number of vehicles and the lag in the construction of transportation facilities, traffic safety and congestion problems have become increasingly prominent. Intelligent traffic, alleviation of congestion problems, and more convenient travel have become the focus of attention. In this context, the vehicular wireless ad hoc network (VANET), as an important part of intelligent transportation, has attracted more and more attention. In-vehicle ad hoc network creatively applies ad hoc network technology to vehicle-to-vehicle communication, enabling drivers to obtain status information and real-time road condition information of other vehicles within the range of beyond the line of sight. The driving environment and other safety aspe...
