[0045] In the present application, unless otherwise clearly specified and limited, a first feature "above" or "below" a second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0046] The present application provides a vehicle electromagnetic anti-collision device, such as Figures 1 to 5 As shown, the electromagnetic anti-collision device includes an anti-collision substrate 21 and an electromagnetic coil 22 arranged on the anti-collision substrate 21. The anti-collision substrate 21 and the electromagnetic coil 22 constitute an electromagnetic unit 2. The vehicle body is provided with multiple electromagnetic units 2, and anti-collision sensors 3 are provided on both sides of the electromagnetic unit 2.

[0047] The electromagnetic anti-collision device in the present application has a simple mechanical structure and is easy to set up. It receives control instructions through the anti-collision substrate 21 and the coil 22, and uses the large amount of electricity and current carried by the new energy vehicle itself to form electromagnetic force. When both our vehicle and the other vehicle are equipped with the electromagnetic anti-collision device, the principle of like poles repel each other is used, and the electromagnetic anti-collision devices of our vehicle and the other vehicle form the same magnetic poles, avoiding direct contact and collision between the vehicles, avoiding damage to the vehicle batteries, reducing the destructiveness of accidents, and protecting personnel safety.

[0048] Furthermore, if Figure 1 , Figure 2 As shown, each anti-collision substrate 21 is provided with a plurality of protrusions, each protrusion is wound with an electromagnetic coil 22 , and the plurality of protrusions are evenly distributed on the anti-collision substrate 21 .

[0049] Preferably, if Figure 3 , Figure 4 As shown, the front, rear, left and right sides of the vehicle body are respectively provided with electromagnetic units 2. It can be understood that the electromagnetic anti-collision device is arranged similarly on the right and left sides of the vehicle body, and is arranged similarly on the rear and front sides of the vehicle body.

[0050] By arranging electromagnetic units 2 at the front, back, left and right of the vehicle, and arranging anti-collision sensors 3 at each electromagnetic unit 2, the vehicle can realize electromagnetic anti-collision function at multiple angles, and can detect vehicles equipped with secondary electromagnetic anti-collision devices around the vehicle through the anti-collision sensors 3 in all directions of the vehicle, and send identification signals to the surroundings with a larger range and wider coverage, thereby effectively reducing the probability of collision.

[0051] The electromagnetic anti-collision device of the present application utilizes the electromagnetic effect. A current is passed through the coil 22 to form a DC solenoid electromagnet with the anti-collision substrate 21. The force generated by the electromagnet is:

[0052]

[0053] The meaning and unit of each character are:

[0054] Working air gap flux, Wb;

[0055] μ0: vacuum magnetic permeability, its value is 4π*10 -7 Wb / A·m;

[0056] N: number of coil turns;

[0057] I: current intensity, A;

[0058] δ: air gap length, m;

[0059] S: Magnetic circuit cross-sectional area, m 2 .

[0060] When the electromagnetic anti-collision device is activated, the current passing through the electromagnetic coil 22 increases rapidly. According to the formula, the increase in current can increase the electromagnetic force generated, so that the two vehicles about to collide will instantly generate a huge mutual repulsion force to avoid vehicle collision.

[0061] After the vehicle stops, the electromagnetic anti-collision device is turned off, the current is cut off, and the vehicle returns to normal.

[0062] like Figure 5 As shown, for the opening and closing of the electromagnetic anti-collision device, the present solution also includes a vehicle electromagnetic anti-collision device control system and control method, wherein the control system is used to control the electromagnetic anti-collision device as described above, and the control system includes:

[0063] Monitoring module, which monitors the opening angle and duration of the brake pedal in real time;

[0064] The monitoring module monitors in real time whether surrounding vehicles send out identification signals, and performs real-time position monitoring on vehicles that receive identification signals;

[0065] A judgment module receives monitoring information from the monitoring module to judge whether the vehicle enters an emergency braking mode;

[0066] A judgment module receives the monitoring information of the monitoring module and judges the distance between the surrounding vehicles equipped with electromagnetic anti-collision devices and our vehicle;

[0067] The control module controls the electromagnetic anti-collision device of the vehicle to start in the emergency braking mode so that the electromagnetic anti-collision device forms a preset magnetic pole when the vehicle is judged to be in an emergency braking mode.

[0068] When it is determined that the magnetic poles of the other vehicle are different from those of our vehicle, the control module controls the electromagnetic anti-collision device of the other vehicle to start, so that the other vehicle forms the same preset magnetic pole as our vehicle.

[0069] Further, the monitoring module is connected to the anti-collision sensor 3, and the anti-collision sensor 3 includes:

[0070] A first sensor, the first sensor is used to send an identification signal to the surrounding environment;

[0071] The second sensor is used to obtain identification signals sent by surrounding vehicles.

[0072] The vehicle releases the identification signal of its electromagnetic anti-collision device to surrounding vehicles through the first sensor. The surrounding vehicles that are also equipped with the electromagnetic anti-collision sensor 3 can receive the identification signal sent by our vehicle through the second sensor of their vehicles, record and update the position of our vehicle in real time for backup.

[0073] Similarly, our vehicle receives the identification signal sent by the first sensor of the surrounding vehicle equipped with electromagnetic anti-collision device through the second sensor, records and updates the position of this vehicle in real time for backup.

[0074] The monitoring module transmits the brake pedal opening angle and duration information to the judgment module. The judgment module compares the received monitoring data with the preset data to determine whether the vehicle is in emergency braking mode.

[0075] In a preferred embodiment, the control system comprises:

[0076] Controller 1, controller 1 is connected to the monitoring module, the judgment module and the control module;

[0077] Actuator: The actuator is connected to the controller 1 and executes the control instructions of the control module.

[0078] Specifically, since the monitoring module monitors and updates the position information of the surrounding vehicles equipped with electromagnetic anti-collision devices in real time, the judgment module judges whether the distance between our vehicle and the surrounding vehicles is less than a preset value based on the monitoring data of the monitoring module. When our vehicle is in emergency braking mode, and it is detected that the other vehicle that may collide with our vehicle has installed an electromagnetic anti-collision device, and the distance between the other vehicle and our vehicle is less than the preset value, the electromagnetic anti-collision device controller 1 of our vehicle sends a control signal to control the actuator to make the electromagnetic anti-collision device form an electromagnetic N pole. At the same time, since the monitoring module monitors the other party's electromagnetic anti-collision device in real time and transmits the monitoring information to the judgment module, the judgment module also includes judging the working status of the electromagnetic anti-collision device of the other vehicle. If it is detected that the other party's electromagnetic anti-collision device is not started, the control module sends an instruction to make the controller 1 start the electromagnetic anti-collision device of the other vehicle to form the same electromagnetic N pole as ours.

[0079] This solution is applicable to new energy vehicles. It utilizes the large amount of electricity and current carried by new energy vehicles. In the above situation, our vehicle and the other vehicle form a huge electromagnetic repulsive force, and uses the principle of like poles repelling each other to prevent the two vehicles from contacting and colliding.

[0080] It should be noted that the electromagnetic anti-collision device in this scheme does not interfere with other safety auxiliary devices and control systems of the vehicle. The electromagnetic anti-collision device in this scheme is only activated and used to assist in avoidance when it is detected that the other vehicle is also equipped with a secondary electromagnetic anti-collision device, and does not affect the operation of other safety avoidance devices of the vehicle. Therefore, in the process of forming mutual repulsive force avoidance, other safety avoidance devices of the vehicle are still working and will not cause collision with other surrounding vehicles.

[0081] In a preferred embodiment, it also includes a power supply module, and the power supply module provides current to the electromagnetic anti-collision device.

[0082] Specifically, after the control module receives the start command of the electromagnetic anti-collision device, the power supply module passes current to rapidly increase the current passing through the coil 22. The power supply module can be connected to the control module, and the control module sends a power supply command to the coil 22.

[0083] The present solution also includes a vehicle electromagnetic anti-collision control method, which is applied to the control system as described above. In a preferred embodiment, the method includes sending an identification signal to the surroundings in real time so that vehicles with electromagnetic anti-collision devices around can detect the electromagnetic anti-collision device of our vehicle;

[0084] The identification signals emitted by the electromagnetic anti-collision devices of surrounding vehicles are obtained in real time to detect whether the surrounding vehicles are equipped with electromagnetic anti-collision devices.

[0085] Methods include:

[0086] Determine whether our vehicle is in an emergency braking mode, and if so, determine whether the electromagnetic anti-collision device meets the first starting condition; wherein, determining whether the electromagnetic anti-collision device meets the first starting condition includes: determining whether the other vehicle is equipped with an electromagnetic anti-collision device, and determining whether the distance between the other vehicle and our vehicle is less than a preset value; if so, the first starting condition is met, and the electromagnetic anti-collision device is controlled to form a preset magnetic pole;

[0087] If the vehicle is in the emergency braking mode, determine whether the electromagnetic anti-collision device meets the second start-up condition; wherein determining whether the electromagnetic anti-collision device meets the second start-up condition includes: determining whether the magnetic poles of the other vehicle and the vehicle are the same;

[0088] If they are different, the electromagnetic anti-collision device of the other vehicle will be activated to make the magnetic poles of the other vehicle and our vehicle the same.

[0089] In a preferred embodiment, the method includes: determining whether the vehicle exits the emergency braking mode, and if so, controlling the electromagnetic anti-collision device to turn off;

[0090] If our vehicle exits the emergency braking mode, we determine whether the other vehicle has turned off its electromagnetic anti-collision device. If not, we control the other vehicle's electromagnetic anti-collision device to turn off.

[0091] In this solution, before an emergency collision, the vehicle automatically triggers the electromagnetic anti-collision device to avoid collision damage to the new energy vehicle, reduce the risk of accidents, protect personnel safety, and protect the vehicle battery.

[0092] In a specific embodiment, a vehicle equipped with the electromagnetic anti-collision device has a real-time signal receiving and sending function through a control system. A first sensor sends a signal to the surrounding area in real time to inform surrounding vehicles that the vehicle is equipped with an electromagnetic anti-collision device. At the same time, a second sensor receives surrounding signals. The first sensor and the second sensor are provided in the front, rear, left and right directions of the vehicle body. When an identification signal of the electromagnetic anti-collision device is received from surrounding vehicles, the vehicle is monitored in real time and the position of the vehicle is updated for backup.

[0093] It can be understood that the range in which the first sensor sends out the identification signal and the range in which the second sensor obtains the identification signal are related to the sensor signal strength and other technologies in the prior art.

[0094] The judgment module determines whether the vehicle enters the emergency braking mode by real-time monitoring of the vehicle. In this solution, the judgment is made by monitoring the opening angle and duration of the brake pedal, and comparing them with the preset values ​​of the opening angle and duration of the brake pedal. When the preset values ​​are exceeded, it is determined that the vehicle enters the emergency braking mode. If it is also monitored that the vehicle that is about to collide with our vehicle is also equipped with an electromagnetic anti-collision device, and the distance between the other vehicle and our vehicle is less than the preset value, the controller 1 sends a control signal to control the electromagnetic anti-collision device actuator to form an electromagnetic N pole. If the electromagnetic anti-collision device of the other vehicle is not at the N pole, the electromagnetic anti-collision device of the other vehicle is controlled to be started to form an electromagnetic N pole. The power supply module causes the current passing through the coil 22 to increase rapidly, thereby increasing the electromagnetic force generated, so that the two vehicles that are about to collide instantly generate a huge mutual repulsion force, and both sides avoid at the same time to avoid a collision.

[0095] After the vehicle stops, the brake pedal is reset, the judgment module receives the monitoring information of the brake pedal from the monitoring module, determines that the vehicle has exited the emergency braking mode, transmits a command to the control module, and controls the actuator to cut off the current. If it is detected that the electromagnetic anti-collision device of the other vehicle is still in the started state, the electromagnetic anti-collision device of the other vehicle is controlled to cut off the current. After both vehicles exit the emergency braking mode, the electromagnetic anti-collision device is turned off.

[0096] It can be understood that, in addition to being connected to the control module, the controller 1 is also connected to other modules of the control system to implement signal and command transmission and reception of each module.
