Wireless charging belt system for providing charging, positioning, navigation and automatic driving for electric vehicle

Abstract

The invention discloses a multifunctional wireless charging belt system which can support wireless multimode automatic charging, automatic positioning, automatic navigation and automatic driving for an electric vehicle during driving and combine intelligent traffic control and communication entertainment as a whole. The system comprises micro blocks and a positioning and navigation technology, wherein the micro blocks divide a road surface into blocks of fixed shapes and are arranged according to sequence numbers; and according to the positioning and navigation technology, the position of the vehicle is determined according to the position of a micro block where a vehicle tire is, and the driving speed and the direction of the vehicle are determined according to the distance between micro blocks and the numbers of the micro blocks passed by the vehicle in a unit time. A technology and a method of sending and receiving information while charging is carried out through electromagnetic resonance or an electromagnetic coupling charging system are also provided. Through the system, the vehicle can be automatically charged; the vehicle can automatically acquire real-time road traffic information, road traffic light information and front-rear vehicle information; the vehicle can automatically select the best way, regulate the best speed and arrive at a destination safely along a road guiding line indication lamp on the road.

Description

technical field [0001] The invention discloses a multifunctional wireless charging belt system that supports wireless multi-mode automatic charging, automatic positioning, automatic navigation, and automatic driving of electric vehicles during high-speed driving, and supports intelligent traffic control and communication and entertainment. It belongs to new energy vehicles. field. Background technique [0002] The wireless and non-contact charging technology has been realized in the laboratory more than ten years ago, and the short-distance non-contact charging technology has been applied in the chargers of telephones and various electric tools. There are three main technologies commonly used: one is electromagnetic induction coupling technology, the other is electromagnetic resonance technology, and the other is radio frequency or microwave technology. The environment where electromagnetic coupling technology can be used is close range: the distance between the charging tr...

AI Technical Summary

Problems solved by technology

Since the charging efficiency of the existing wireless non-contact charging technology is inversely proportional to the square of the distance between the charging transmitter and the receiver, the farther the distance is, the lower the efficiency is, and the distance between the site of an electric vehicle and the road is generally 200-500 mm Therefore, the charging efficiency of these wireless non-contact charging technologies used in the field of electric vehicles is relatively low

It was also proposed to install a height-adjustable bracket under the chassis of the car to reduce the distance between the receiving antenna and the road. This method is acceptable for non-contact charging in the parking lot when the electric car is stationary, but for high-speed For electric vehicles in motion, if the distance between the receiving antenna and the road is too small, any bumps will cause serious safety hazards

In addition, the direct use of the existing wireless non-contact charging technology in the field of electric vehicles will also cause serious electromagnetic radiation and energy waste

Someone once proposed to use the pressure sensor to detect the passage of the vehicle before turning on the charging current. However, since the pressure sensor cannot judge whether it is an ordinary car or an electric car, it still produces a large number of non-electric cars or cars that do not need to be charged. Electromagnetic radiation and waste charging power

To sum up, the shortcomings and deficiencies of existing wireless non-contact electric vehicle charging technology and solutions include: 1. Low charging efficiency; 2. Large amount of radiation, resulting in electromagnetic radiation and energy waste

In order to achieve the last two stages, there must be cooperation and interaction of road infrastructure, and it will be difficult to achieve efficient and fully autonomous driving completely relying on the vehicle's own detection
