Problems solved by technology

[0002] The current high incidence of traffic accidents in road trips is due to a variety of reasons, among which drivers themselves have complex and changeable personal conditions (drinking, fatigue or sleepiness) and negative emotions (anger, impatience, depression, ecstasy, etc.), the traffic accidents caused account for the majority; on the other hand, the occurrence of traffic accidents also stems from the lack of timely reminders and early warnings between drivers. The current reminder method is limited to the rough vision of the driver. judge

Embodiment 1

[0039] Embodiment 1: a kind of early warning system for safe driving of a short-distance vehicle, including a radar sensor positioned around the vehicle body, a vehicle body motion perception sensor module, a driving trajectory prediction module, a vehicle communication network module and a display unit; the radar sensor is used to obtain In the front, rear, left, and right sectors of the vehicle body, the imaging between adjacent vehicles and the vehicle body establishes the location topology of the vehicle neighborhood network. The adjacent vehicles are vehicles within the range of the current vehicle radar sensor. ; The vehicle body motion perception sensor module is used to obtain the steering wheel rotation information, acceleration / braking information, tire pressure information and fuel tank capacity information of the car, and send the above information to the driving trajectory prediction module; the driving trajectory prediction module, according to the vehicle The inf...

Embodiment 2

[0052] Embodiment 2: A method for early warning of safe driving of short-distance vehicles, real-time acquisition of images between the current vehicle and adjacent vehicles, adjacent vehicles are vehicles within a set distance range centered on the current vehicle; through the vehicle steering wheel rotation information , acceleration / braking information, tire pressure information and fuel tank capacity information to predict the driving trajectory of the car at the next moment; through the automotive communication network, the driving trajectory of the current car at the next moment and the image between the adjacent vehicle and the adjacent vehicle are sent to the adjacent Vehicles, and accept the above information sent by adjacent vehicles to realize the safe driving warning of the current vehicle.

[0053] In this embodiment, the real-time acquisition of the image between the current vehicle and the adjacent vehicle can be replaced by the straight-line distance and relativ...

Embodiment 3

[0055] Embodiment 3: Automobile safe driving early warning system, including short-distance and long-distance automobile safe driving early warning systems.

[0056] Long-distance vehicles use remote broadcast positioning detection system: an early warning system composed of China's own LTE-V broadcast system, differential global precise DGPS physical positioning system combined with electronic maps, to warn areas outside the visual range, remote emergency traffic event model , For example: a relatively fast-moving car a little farther away, a tire burst, a sudden turn, etc. Predict the driving trajectory of the car based on the car's long-distance early warning system, and deduce it based on the driver's common driving awareness (driving common sense) model, predict possible potential car accidents, and broadcast in the minimum dynamic neighborhood car network; finally pass The potential car accident screen of the car neighbor network provides early warning indication; by sco...

Abstract

The invention discloses an automobile safe driving early-warning system, and comprises short-distance/long-distance automobile safe driving early-warning system and methods. The short-distance automobile safe driving early-warning system comprises radar sensors arranged in the periphery of a vehicle body, a vehicle body motion sensing sensor group, a driving track prediction module, an automobile commutation network module and a display unit. An early warning system of dynamic neighbor automobile network is constructed for a vehicle and neighbor vehicles in the surrounding, the whole constructed system is displayed in a vehicle-mounted screen terminal in real time, driving accidents can be avoided effectively, and hidden safety troubles are reduced.

Description

technical field [0001] The invention relates to the field of safe driving, in particular to an early warning system and method for safe driving of automobiles. Background technique [0002] The current high incidence of traffic accidents in road trips is due to a variety of reasons, among which drivers themselves have complex and changeable personal conditions (drinking, fatigue or sleepiness) and negative emotions (anger, impatience, depression, ecstasy, etc.), the traffic accidents caused account for the majority; on the other hand, the occurrence of traffic accidents also stems from the lack of timely reminders and early warnings between drivers. The current reminder method is limited to the rough vision of the driver. judge. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention provides a car safety driving early warning system, through [0004] The early warning system of "dynamic neighborhood car network" is c...
