Description

Bionic vehicle motion state warning display device, system and application method thereof

Technical Field

The invention relates to the technical field of traffic signals, in particular to a motion state warning display system of a bionic vehicle.

Background

In recent years, in the field of traffic safety, the driving safety factor of vehicles and the safety of pedestrians have gained more and more attention from national governments and society. More and more traffic regulations also stipulate that vehicles need to actively avoid pedestrians on roads so as to reduce traffic accidents. However, the personal safety of pedestrians is seriously affected by a series of problems such as drunk driving, road rage, sudden diseases and the like, and the main generation of the problems is an unspecified factor, so that a solution is difficult to find at present.

The pedestrian danger degree detection method at the present stage mainly comprises the steps of calculating the collision time or the collision area of a pedestrian relative to a running vehicle through a complex dynamics fitting method, and then manually dividing the danger grades of different collision times or collision areas through a safety system designer to judge the danger degree of the pedestrian. The method aims at solving the problems that the computation cost of the model is high, the fitting effect is poor, the pre-judging performance is poor, the applicable scene is limited and the like when the pedestrian collision time or the collision area is computed through a complex dynamics model. Aiming at the problems that different collision time or the danger levels of collision areas are manually divided by designers, the method has strong subjectivity, limited applicable scenes, incapability of large-scale popularization and the like.

In summary, for the safety problem of pedestrians, the following problems and potential safety hazards mainly exist in the current motor vehicles and non-motor vehicles on the market:

1. for vehicles running on roads, such as motor vehicles and non-motor vehicles, including electric scooters, with a movement speed of more than 15 km per hour, from the perspective of a third party, if the movement mode and the movement track of the vehicles cannot be immediately judged to be safe without the help of external tools, whether hidden dangers harmful to others exist.

2. According to the latest specification, the newly-marketed electric bicycles need to be reminded by alarm sound when the driving speed is more than 15 kilometers per hour, but the alarm sound is not high and can be heard only when the distance is very close, but the alarm sound cannot be too high, otherwise, the sound disturbs residents and generates noise pollution.

3. Under the current environment that driving is common, the road rage is a topic which is mentioned repeatedly, but the vehicle adhered with the 'practice' mark is less troubled by the road rage, the reason is that from the aspects of warning and prompting, the yellow practice mark can be hung to effectively inform other people driving the vehicle, and various irregular driving behaviors can exist or occur on the vehicle, so that the prejudgment is improved, the psychology of enemy is reduced, and most vehicles are far away from the practice vehicle. This is the role played by the bionic warning color and warning stripe. In real life, all vehicles cannot be hung with practice marks, and the actual conditions of the vehicles cannot be reflected correctly and in real time through the hanging marks.

4. In the internet of things technology, the technology needs higher technical cost and brand-new software and hardware support, and is ineffective for vehicles and pedestrians without an internet of things system because information can not be exchanged.
