TECHNICAL FIELD

[0001] The application relates to the technical field of automobile safety control, in particular to an active limiting device for a throttle pedal. BACKGROUND

When the driving member 310 is positively rotated by a preset angle, the support rod body 221 swings around the pin shaft 140 from the retracted state to the top support state. When the driving member 310 is reversely rotated by a preset angle, the support rod body 221 swings around the pin shaft 140 from the top support state to the retracted state. The specific value of the preset angle can be obtained by simple calculation, which will not be described here.

[0055] As shown in Figure 8 In the embodiment, the position information of the vehicle is acquired by the GPS unit 420 and transmitted to the control unit 410, and the control unit 410 judges whether the vehicle is in the target area according to the position information, and the target area preferably comprises an enclosed area corresponding to an electronic fence in the embodiment. It should be noted that the specific operation of judging whether the target area (i.e. the area of the electronic fence) is in the target area according to the position information is prior art, but in order to more fully describe the scheme of the embodiment, the embodiment simply lists one way:

[0056] Firstly, the control unit 410 pre-stores the geometric parameters of the target area (the electronic fence), including:

[0057] Coordinate range: the longitude and latitude boundary values (such as the minimum and maximum longitude and latitude) of the electronic fence;

[0058] Shape rule: circle (center + radius) or polygon (sequence of vertex coordinates);

[0059] Secondly, real-time position data analysis;

[0060] I. Acquire the real-time position information (longitude, latitude, time stamp) of the vehicle from the GPS unit 420:

[0061] II. Coordinate conversion: convert the GPS coordinates into a coordinate system consistent with the electronic fence (such as WGS84 to UTM local coordinate system);

[0062] Thirdly, the geometric matching algorithm, according to the shape of the electronic fence, the following method is used to judge the position relationship:

[0063] Circular fence: calculate the Euclidean distance from the vehicle position to the center, if the distance ≤ radius, it is determined that it is “in the fence”.

[0064] Polygon fence: use the Ray Casting method or the Winding Number method to judge whether the point is inside the polygon.

[0065] In the embodiment, if the vehicle is in the target area, the control unit 410 controls the driving member 310 to rotate forward by a preset angle, so that the support rod body 221 swings to the supporting state to limit the accelerator pedal 500 from being stepped on, and when the vehicle is not in the target area, the support rod body 221 remains in the retracted state, and the driver can step on the accelerator pedal 500 greatly.

[0066] In the embodiment, the control unit 410 is preferably an ESP32 microcontroller, and the GPS unit 420 is preferably a U-blox NEO-6M module.

[0067] As shown in Figure 4 the embodiment, the control assembly 400 further includes a Hall sensor 430 and a magnet 440. The Hall sensor 430 is arranged on the outer side of the case body 110 and is located on the same side as the support rod body 221. The Hall sensor 430 is electrically connected to the control unit 410 in a wired or wireless manner. The magnet 440 is arranged on the support rod body 221 and is used in cooperation with the Hall sensor 430 to generate a signal.

[0068] As shown in Figure 4 the embodiment, when the support rod body 221 is in the retracted state, the control unit 410 receives a first signal of the Hall sensor 430, and when the support rod body 221 is in the supporting state, the control unit 410 receives a second signal of the Hall sensor 430. The position of the support rod body 221 is monitored by the Hall sensor 430 to obtain the real-time state of the support rod body 221. The control unit 410 can also feed back information to the user's mobile phone through the Internet of Things, thereby achieving the effect of real-time detection.

[0069] As shown in Figure 9 the embodiment, the working process of the active limiting device is as follows:

[0070] Step one, start;

[0071] Step two, initialization, including: obtaining the signal of the Hall sensor 430 and making a judgment;

[0072] If the control unit 410 receives the first signal of the Hall sensor 430, it indicates that the support rod body 221 is in the retracted state, and the control unit 410 does not feed back;

[0073] If the control unit 410 receives the second signal of the Hall sensor 430, it indicates that the support rod body 221 is in the supporting state, and the control unit 410 sends a first control signal to the driving member 310. The driving member 310 reversely rotates by a preset angle to make the support rod body 221 swing to the retracted state;

[0074] Step three, obtaining the position information of the vehicle;

[0075] Step four, the control unit 410 determines whether the vehicle is in the target area according to the position information;

[0076] If not, return to step three;

[0077] If yes, go to step five;

[0078] Step five, determine whether the vehicle is in the jacking state according to the signal of the Hall sensor 430;

[0079] If yes, return to step three;

[0080] If not, the control unit 410 sends a second control signal to the driving member 310, and the driving member 310 rotates forward by a preset angle, so that the support rod body 221 swings to the jacking state, and then returns to step three.

[0081] The above is only a specific implementation of the present application, and those skilled in the art can clearly understand that, for the convenience and brevity of description, the specific working process of the system, module and unit described above can refer to the corresponding process in the foregoing method embodiments, which will not be described here. It should be understood that the protection scope of the present application is not limited to this, and any person skilled in the art can easily think of various equivalent modifications or replacements within the technical range disclosed in the present application, and these modifications or replacements should be covered within the protection scope of the present application.
