Embodiment 1

[0046]For oil-braked automobiles, the emergency braking brake 8 includes an electromagnetic exciter 14, a brake pump and a brake cylinder 12, and the brake pipeline 22 of the automobile communicates with the oil chamber 15 of the brake cylinder 12 and the brake pump 24 respectively, and the electromagnetic excitation The device 14 is connected to the push rod 13 of the brake pump. When the push rod 13 pushes the piston in the brake pump 24 to move, the piston pushes the brake oil from the oil chamber 15 to the brake cylinder 12 for braking, and the oil chamber of the brake pump 24 A pressure sensor 10 is arranged in the brake pipe 22 connected with the brake pipe 15 . Its working process is as follows: After the controller sends out a signal, the electromagnetic force generated by the electromagnetic actuator 14 is transmitted to the push rod 13, and the push rod 13 pushes the piston of the brake pump, and the piston moves to transfer the oil in the oil chamber 15 of the brake ...

Embodiment 2

[0048] For an air-braked automobile, the emergency brake 8 includes a housing 21, an air cylinder 16 and a driver 19, and the housing 21 is connected to the brake pipeline 22, the air cylinder 16 and the wheel 20 of the automobile, and the driver 19 passes The push shaft 18 is movably connected with a hollow swing arm 19, and the side wall of the swing arm 19 is provided with three ventilation holes 23. When the swing arm 19 swings, one of the ventilation holes 23 is closed and the other two ventilation holes 23 communicate with each other. The brake pipe 22 , The gas storage cylinder 16 and the wheel 20 can be communicated in pairs, and the pressure sensor 10 is arranged in the brake pipe 22 . Its working process is as follows: when the automobile runs normally without any danger, the brake pipe 22 is connected with the wheel 20, that is, the original brake system works normally. Wheel 20 is not connected, and gas cylinder 16 is connected with wheel 20, and the gas of gas cyl...

Abstract

The invention discloses a method of prewarning running automobiles and avoiding collision, which comprises the following steps: the distance L between an automobile and an obstacle is collected by utilizing a macrometer; the running speed V information of the automobile is collected by the macrometer; and the controller outputs a control signal to a warner or a forced speed reducer or an emergency brake and an emergency brake and rear warning lamp according to different situations. The invention further provides a system for prewarning running automobiles and avoiding collision, which comprises a hand brake switch, a steering switch, a macrometer, a velometer, a data collecting and processing unit and a controller, wherein the controller is used for receiving signals of the data collecting and processing unit and outputting control signals to the warner or forced speed reducer or emergency brake and the emergency brake and rear warning lamp. By adopting the scheme, during automobile running, not only a driver can be warned to avoid collision accidents, but also the forced speed reducer or the emergency brake and the like can be automatically controlled and started, to help the driver take measures to prevent the occurrence of accidents.

Description

technical field [0001] The invention belongs to the technical field of automobile equipment, and in particular relates to a driving warning, collision avoidance method and a driving warning, collision avoidance system. Background technique [0002] With the development of society, automobiles have become an indispensable means of transportation in people's lives, and the problem of traffic safety has become one of the problems to be solved urgently. [0003] At present, the protection of automobiles mainly includes two aspects: one is the anti-collision warning device, such as the reversing radar, which only measures the automobile and the objects next to it during the low-speed parking process of the automobile, mainly to assist the driver in parking, and its reliable formation The second is a mechanical buffer system, such as the No. 02153212 patent application of the State Intellectual Property Office of China, which discloses a car anti-collision device. The rod is conn...
