Technical Field

Transport, signal detection.

Background

With the large-scale popularization of electric vehicles (electric bicycles or two-wheeled electric vehicles), more and more electric vehicles run on sidewalks and are parallel to people and vehicles. In consideration of the crowded state of Chinese streets, the fact that the electric vehicle runs on the sidewalk more or less becomes accepted by pedestrians. However, the electric vehicles running on the sidewalks often run in the opposite direction, and the owners of the electric vehicles running in the opposite direction not only do not feel that the owners violate the traffic rules, but also continuously press the loudspeakers to enable the pedestrians walking according to the traffic rules to give way.

Although traffic policemen manage this phenomenon during central regulation, they are still overwhelmed and far beyond the manpower and material resources of traffic policemen. From another perspective, the nationality is not very conscious of the law, even if the traffic police dissuade them, they still do the job of going backwards on the sidewalk as long as they are not.

In fact, because the electric vehicle is small and flexible, the electric vehicle can not only run reversely on a sidewalk, but also frequently run reversely on a non-motor vehicle lane and even a motor vehicle lane.

Disclosure of Invention

The invention provides a retrograde motion warning device for an electric vehicle, which reminds a vehicle owner of complying with traffic rules and not carrying out retrograde motion.

The problems to be solved are as follows: the electric vehicle runs in the reverse direction on a non-motor vehicle lane and a sidewalk, even runs in the reverse direction and is rushed straight on the motor vehicle lane.

The technical scheme is as follows: the electric vehicle retrograde motion warning device consists of a detection device, a control device and a reminding device. The method comprises the following steps that a driving direction detection device is arranged on the electric vehicle to detect whether the electric vehicle drives reversely on a non-motor vehicle lane and a sidewalk or even on a motor vehicle lane; judging whether the electric vehicle runs in the reverse direction or not through a control device; and when the electric vehicle is determined to run reversely, the reminding device is started, and the vehicle owner is reminded of not running reversely through voice. When reverse driving is still detected after multiple times of reminding, the power supply of the electric vehicle can be automatically cut off, so that a vehicle owner can not drive and can only push the vehicle.

Has the advantages that: the electric vehicle retrograde warning device is helpful for improving the consciousness that citizens consciously obey the traffic rules, can effectively control the electric vehicle retrograde, maintain the traffic order and avoid traffic accidents.

Compared with the prior art: reports on how to technically avoid the electric vehicle from going backwards on the sidewalk are rare, so related patents are rare, and the following three patents are also limited to search keywords 'electric vehicle' + 'going backwards' and are slightly related.

In examined patent 201910291553.X, a method, an apparatus, a device and a storage medium for detecting the reverse running of a shared electric vehicle are disclosed, wherein the current GPS signal strength is determined according to the current GPS data by acquiring the current GPS data of the shared electric vehicle in real time; when the current GPS signal intensity is greater than or equal to a preset GPS signal threshold value, acquiring target GPS data of the shared electric vehicle within a preset time period, and generating track information according to the target GPS data; the track information is compared with the preset map information, whether the shared electric vehicle drives in the wrong direction or not is judged according to the comparison result, the state of the shared electric vehicle driven in the wrong direction can be accurately acquired, parameter support is provided for follow-up management and control of the shared electric vehicle, the safety of users and pedestrians in traffic trip is improved, the occurrence probability of traffic accidents is reduced, and the riding experience of the users is improved.

The invention patent 201811576876.5 provides a method for recording the violation of the electric vehicle, which comprises the following steps: the server stores an electronic map and basic geographic information, and an electronic fence is arranged in the electronic map for an area where the electric vehicle is likely to have a converse violation; the mobile terminal on the electric vehicle sends a data packet to the server at regular time, and extracts the electric vehicle motion state information of each positioning point from the data packet; the electric vehicle motion state information at least comprises positioning moment information, speed information, coordinate information and moving azimuth information; acquiring an average azimuth angle of the electronic fence; when the electric vehicle passes through a certain electronic fence, when an included angle between a moving azimuth of a locating point in a data packet sent by the electric vehicle and an average azimuth of the electronic fence exceeds a set threshold value, the locating point is judged to be a retrograde locating point, the first data packet sent after the electric vehicle enters the electronic fence is judged, and if the retrograde locating point in the data packet exceeds the set threshold value, the electric vehicle is judged to violate the retrograde rule.

The invention patent 201810529875.9 discloses a road safety anti-reverse device, which structurally comprises a bottom plate, a guide rod, a guide shaft sleeve, a steel wire rope, a tension spring, a rocker arm plate, a gear, a plate spring, a barb roller, a wedge block, a lower pressing block and a cover plate, wherein the barb roller comprises a barb part, a tooth part and an installation part, and the gear is rotatably installed on the bottom plate; the barbed part is arranged between the two tooth parts, the rocker arm plate is fixed on a gear shaft of the gear, the lower end of the rocker arm plate is tied in the middle of the steel wire rope, the barbed part is hidden in the cover plate when the tension spring is in a relaxed state, the barbed part faces to the rear side, and when the steel wire rope is pulled under stress, the gear and the barbed roller are driven to rotate, so that the barbed part extends out of the cover plate and acts on the automobile tire part; the device is in a non-triggering state at ordinary times, only generates a triggering tire puncturing effect on a passing retrograde motor vehicle with certain weight, and cannot be triggered due to the fact that self weight cannot reach a preset condition when the passing retrograde motor vehicles such as pedestrians, electric vehicles and the like pass.

Detailed Description

There are various detectors that can detect whether an object is approaching or departing, for example: the doppler meter emits ultrasonic waves of a known frequency while measuring the frequency of the reflected wave, and determines whether the opposite object is approaching or departing from the object according to whether the frequency of the reflected wave increases or decreases. Therefore, the simplest method is to install a detector on the electric vehicle, which simultaneously detects whether a plurality of objects are approaching or departing, and basically determine whether or not the vehicle is moving backwards by the ratio of the approaching object to the departing object. Of course, this method is less suitable for riders who prefer to overtake, and therefore the more complex detector should be one that determines the face ratio, since during reverse driving more face images are detected than are the back of the head. The monitor can also be used to determine whether the trunk is on the left or right side of the electric vehicle, plus the pedestrian volume to determine whether the electric vehicle is traveling on the sidewalk in the reverse direction.

To avoid the electric vehicle rider turning off the system, it is preferable to mount the retrograde detector in the electric vehicle headlight.
