Embodiment Construction

[0031] The technical content of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] An actual scene on a highway such as figure 1 shown. When the emergency event source in the figure—vehicle E (ie, the vehicle)—has an emergency event, such as abnormal tire pressure or early potential hazards, this will cause the vehicle E to stop suddenly. At the same time, vehicle E generates an emergency advisory message (EAM) and broadcasts it to nearby potential emergency collision vehicle (ECV) vehicles N1, N2, N3, N4 and N5. The EAM broadcast range is vehicles within a certain distance (for example, 500 meters) from the front, rear, left, and right sides of the emergency event source vehicle E.

[0033] like figure 1 As shown, the rear vehicle N4 is on the same trajectory as the vehicle E and is closest to the rear of the vehicle E. The rear vehicle N4 is the most dangerous vehicle compared t...

Abstract

The invention discloses an early warning information sending method and receiving method used for a V2V communication system and vehicles thereof. In the early warning information sending method, a sending vehicle sends broadcasting messages, the content of the broadcasting messages includes an ID list field and a consultation information field of high-danger vehicles, and the consultation information field is consultation information of specific behaviors of the high-danger vehicles. In the early warning information receiving method, a receiving vehicle receives the broadcasting messages and obtains the ID list of the high-danger vehicles contained in the broadcasting messages, the receiving vehicle judges whether the ID list of the high-danger vehicles includes the ID of the receiving vehicle, if yes, the receiving vehicle emits an early warning instruction, and if not, the receiving vehicle updates the state information. Under an emergency, a more reliable processing mechanism is provided to the vehicles in a high danger state.

Description

technical field [0001] The invention relates to a method for sending and receiving early warning information for a V2V (vehicle-to-vehicle) communication network, and also relates to a vehicle using the method, belonging to the technical field of the Internet of Vehicles. Background technique [0002] In V2V communication, many applications or services prefer broadcast transmissions, such as detour navigation, accident alerts and constructive warnings, etc. [0003] Cooperative Collision Warning (CCW) is a safety application that uses V2V communication to prevent vehicle collisions. The ultimate goal of CCW is to achieve 360-degree driving situation awareness, so that the vehicle can alert the driver of imminent threats without expensive equipment. Examples of CCW applications include Forward Collision Warning (FCW), Lane Change Assist (LCA) and Electronic Emergency Brake Light (EEBL). [0004] In FCW, the vehicle uses information received from surrounding vehicles and the...
