When anti-terrorism and anti-riot tasks are executed, suspected vehicles need to be stopped forcibly at many times, and the suspected vehicles are stopped by adopting the traditional passive stopping modes such as obstacle arrangement and obstacle setting. For example, CN2448661 discloses a "steel nail device for stopping a car", wherein a plurality of steel nails are arranged on a bottom belt in a plurality of groups of equilateral triangles and riveted by rivets, the tips of the steel nails are triangular cones, and air release holes are penetrated from top to bottom from the edge to the bottom belt. The escaping vehicle can not avoid the steel nail, and the tire can be punctured easily, the gas in the tire can be discharged instantly through the air leakage hole, and the escaping vehicle can not run. The automobile escape blocking device is widely applied to police service to block escaping vehicles, prevent the vehicles from running, and reduce accidents which cannot be met in the automobile escape process, personal injuries and deaths and vehicle damages. However, the conventional passive blocking mode has poor blocking effect on the suspected vehicle with high maneuvering capability and the chasing block that the suspected vehicle escapes. Therefore, it is required to develop a vehicle intercepting apparatus having a strong intercepting capability.

CN110103907A discloses "an active vehicle intercepting apparatus" attached to a target vehicle surface for: measuring a current speed of the target vehicle; judging whether the current speed is greater than a preset value or not, and if so, establishing communication connection between a first wireless communication module of the device and a second wireless communication module of the target vehicle; and sending a braking command or a control program to an Electronic Control Unit (ECU) of the target vehicle through communication connection, so that a power system of the target vehicle stops working. The vehicle interception device can actively and quickly control dangerous vehicles, and effectively guarantees the safety of main facilities, places and people.

CN210773691U discloses an anti-terrorist intercepting vehicle, which comprises a vehicle body and a vehicle cabin, wherein a controller, a telescopic railing and a microwave gun are installed in the vehicle cabin; the tail end of the controller is also connected with a lead screw, the lead screw pushes the controller and the telescopic railing to extend out of the cabin, the lead screw is fixed on the linear guide rail, and the lead screw is sequentially connected with a coupler, a speed reducer and a motor; the rear part of the vehicle body is also provided with an infrared camera and a speed measuring radar; the microwave cannon is communicated with a circuit of the telescopic railing through the collision switch through the controller, and the impact railing triggers the microwave cannon to emit electromagnetic waves. This vehicle, the effect side is in the antiterrorist, can set up the card at random, prevents criminal's vehicle and marchs, and suspected vehicle strikes the railing and triggers the powerful electromagnetic wave of microwave gun transmission promptly, forces the suspected vehicle to flame out and parks. Because the multistage telescopic railing is adopted, the total extension is not less than 5m, the current road surface can be completely blocked, and the vehicle cannot be forcibly punched and clamped.

The technical solutions disclosed in the above two patent documents are a useful attempt in the technical field.
