Embodiment Construction
[0022] The vehicle-to-vehicle distance warning system includes a vehicle-mounted unit and a roadside unit. The vehicle-mounted unit is installed on different training vehicles. Each coach vehicle in the system is equipped with a vehicle-mounted unit, and the roadside unit is installed in the training field.
[0023] In the vehicle-mounted unit, the vehicle-mounted processor is used for signal processing, responsible for issuing instructions to the communication module, sending the current position information of the coach vehicle to the roadside unit, issuing instructions to the communication module, receiving instructions from the roadside unit, and responsible for starting or stopping The early warning command and entry prohibition command are transmitted to the warning module; the positioning module is used to accurately determine the specific location of the training vehicle to which it belongs (“belonging” refers to the training vehicle equipped with the vehicle system), an...

The invention reveals a coach vehicle distance early warning system. The system includes a plurality of coach vehicles, each coach vehicle is provided with a vehicle-mounted unit, a road side unit is arranged in a training field, the vehicle-mounted unit includes a positioning module, a vehicle-mounted processor, a warning module and a vehicle-mounted communication module, the road side unit includes a map module, a road side processor and a road side communication module, and the road side communication module communicates with the vehicle-mounted communication unit of each vehicle-mounted unit. Through information interaction between the vehicle-mounted units of the coach vehicles and the road side unit, the coach vehicle distance early warning system judges risks of occurrence of an accident and performs early warning, and prompts a student on a coach vehicle to pay attention to keeping distance with a coach vehicle which enters single-item practice ground in the front, or the student is forbidden from entering the practice ground, and enters the field to practice after the coach vehicle in the front completes practice action, thereby avoiding occurrence of an accident, and improving safety of driving of the coach vehicles.
Description
technical field [0001] The present invention relates to the technical field of intelligent transportation, in particular to a design method for a vehicle-to-vehicle distance warning system based on V2X technology. Background technique [0002] Although the students drive the coach car at a low speed on the driving school practice field, due to the unfamiliar operation of the students, there are often many vehicles in the practice field for the same single item (such as curve driving, reversing and storage, etc.) in the practice field. When practicing the coach car, there are often misoperations, and there are major safety hazards. Accidents between coach cars in the practice field occur from time to time across the country. [0003] Although there are also some technologies and products of emergency braking devices for trainers, they are basically implemented when trainees practice the trainer and mistakenly apply the accelerator when the brakes are stepped on or when pedest...
