Intelligent vehicle control system and method based on intelligent transportation platform

Abstract

The invention relates to an intelligent vehicle control system and method based on an intelligent transportation platform. The system comprises an intelligent vehicle controller, a closed electromagnetic guide rail, an electromagnetic sensor, a steering engine, a motor driving module, a speed measuring module, an infrared distance measuring module, a radio frequency identification module, a radio frequency coil and a signal generator. The control method includes the steps that intelligent vehicles autonomously run along a set road of the intelligent transportation platform, the speeds of the vehicles are controlled, the vehicles run according to a formation, and the vehicles run at an intersection according to traffic rules. The function of tracking the intelligent vehicles is completed through the electromagnetic sensor, and the problem that when a photoelectric or camera sensor is adopted, the sensor can be easily disturbed by visible light is solved. Formation driving control is achieved based on infrared distance measurement, and the problems that when an ultrasonic wave distance measuring technology is adopted, influences caused by the temperature of the environment are serious, and the accuracy rate of detection is low are solved. The problem that because a control signal and a signal lamp can not be synchronous when the intelligent vehicles pass through an intersection, the vehicles jump the red light is solved based on the radio frequency identification technology.

Description

technical field [0001] The invention belongs to the field of intelligent transportation, and relates to an intelligent vehicle control system and method based on an intelligent transportation platform. Background technique [0002] Due to the development of the global economy and the continuous growth of urban population and motor vehicle ownership, most cities in the world are facing great traffic pressure. Facing the development trend of world globalization and informationization, traditional transportation technology methods are no longer available. To adapt to the requirements of economic and social development, the development of intelligent transportation is an inevitable choice for the development of the transportation industry. With the rapid development of the world economy and the rapid increase in the penetration rate of automobiles, automobiles bring a lot of convenience to people's lives and cannot be ignored. problems, such as traffic congestion, driving safety...

AI Technical Summary

Problems solved by technology

[0004] The existing intelligent vehicle control system generally uses ultrasonic distance measurement to complete the control of intelligent vehicle formation driving. The problems of this method are: it is greatly affected by the ambient temperature; the emission angle is large, resulting in low detection accuracy and wrong parking; The device is bulky and difficult to install

Since the permanent magnet control cannot be synchronized with the signal light at the intersection, it can only control the intelligent vehicle to stop at a fixed position, and cannot realize automatic parking under the control of the signal light, that is, driving under the traffic rule of "stop at red light and go at green light"; (2) adopt Electromagnetic induction technology, the electromagnet is buried under the road surface, and the magnetic field detection equipment is installed on the intelligent vehicle. When the red light at the intersection is on, the electromagnet is energized to generate an electromagnetic field. The magnetic field detection equipment detects the electromagnetic signal, and the intelligent vehicle stops.

Although the traffic rule of "stop at red light and go at green light" has been completed, the effective distance of the magnetic field signal generated by the electromagnet is small, and the smart vehicle often cannot detect the electromagnetic signal when the red light at the intersection is on, causing the smart vehicle to run the red light
