Embodiment 1

[0096] Example 1 as Figure 5 As shown, vehicle I is a data fusion release vehicle, and vehicle II is a fusion data receiving and processing vehicle. Both Vehicle I and Vehicle II are equipped with ADAS, V2V module, position sensor and motion sensor. No V2V modules are installed on the remaining vehicles.

[0097] When vehicle I performs data fusion and release, the specific process is as follows:

[0098] S11, data fusion release The position sensor on the vehicle collects the position, direction and speed data of the vehicle (lon p 0,lat p 0,heading p 0,speed p 0).

[0099] S12, data fusion and release The motion sensor on the vehicle collects the acceleration and angular acceleration data of the vehicle (a px 0,a py 0,a pz 0; ω px 0, ω py 0, ω pz 0).

[0100] S13. Determine whether the sensor in the ADAS on the data fusion release vehicle has detected a vehicle around the vehicle. If a vehicle is detected, perform step S14; otherwise, skip to step S11.

Abstract

The invention relates to an ADAS and V2V combined beyond visual range sensing and publishing method and system. The sensing and publishing method comprises data integration publishing process and integrated data receiving handling process; the data integration publishing process utilizes environment sensing data published and integrated by a V2V module, the integrated data receiving handling process utilizes the integrated data and performs collision warning or risk prompt by using a scene classification handling algorithm. By performing state inverse, data filtering and data integration on the collected data of the traditional ADAS vehicle with the V2V module, the sensing and application range of the equipped V2V module vehicle is improved, the application and promotion progress of the V2V module is greatly promoted from the technical angle. The sensing range of the vehicle and the reliability of the V2V application can be improved, and the dependency on an installation rate by the V2V application is reduced.

Description

technical field [0001] The invention belongs to the field of intelligent vehicle environment fusion perception, and in particular relates to a beyond-the-horizon perception and release method combining ADAS and V2V. Background technique [0002] Currently, vehicles are already equipped with various sensors for sensing the surrounding environment, such as rain sensors, brightness sensors, position sensors, motion sensors, and safety assistance sensors. Among them, video, microwave / millimeter wave / lidar, etc. are mainly used for safety assistance. These sensors all regard the vehicle as an isolated individual to perceive the surrounding environment. This bicycle sensor sensing method has a limited sensing range and cannot perceive the environment beyond the visual distance. Although vehicle-to-vehicle coordination based on V2V (Vehicle to Vehicle) communication can enable vehicles to perceive the environment beyond the line of sight, there is a major defect in this method, t...
