[0002] The charging equipment located on the vehicle needs to be parked in the rechargeable area of the charging equipment when the vehicle is parked. It has requirements in the horizontal, front, rear, left, and right directions. At present, the front and rear positioning is mainly completed through the speed bump, and the left and right depends on the driver's feeling. , but there is no detection ability after parking. It can only be confirmed by whether the electrical connection can be completed after the charging device is connected. There is no small hidden danger here. At the same time, the charging device does not have the function of detecting the relative height of the vehicle. detection and redundancy

[0043] Obtaining the time at which the detection signal arrives at each receiver 4 in the array of receivers 4, wherein the detection signal is sent by at least one generator 3 at a first point in time; based on the detection signal arriving at each receiver 4 in the array of receivers 4 the time of the generator 4, determine the first coordinate and the second coordinate of the at least one generator 3; wherein, the second coordinate is determined based on the system clock synchronization method; based on at least one history of the at least one generator 3 At least one of the coordinates, the speed of the vehicle, the acceleration of the vehicle, at least one external feature determines the validity of the first and / or second coordinates of the at least one generator 3 .
[0044] When generator 3 is set at charging terminal 1:
[0045] In response to determining that both the first and second coordinates of the at least one generator 3 are valid, based on the first and secon...

The present invention provides a method for judging the validity of a vehicle spatial positioning system. The vehicle is equipped with a power receiving terminal. The method includes: acquiring the time when a detection signal arrives at each receiver in a receiver array, and the detection signal is determined by at least one of the receivers in the receiver array. a generator emits at a first point in time; determining a first coordinate and a second coordinate of the at least one generator based on the time at which the detection signal arrives at each receiver in the receiver array; based on the at least one generator At least one historical coordinate of said vehicle, said vehicle's speed, said vehicle's acceleration, at least one external feature, determine the validity of said at least one generator's first coordinate and / or second coordinate; The obtained signal data is judged many times to eliminate invalid data caused by various factors, improve the reliability of the final data, and improve the accuracy of the final data through data fitting.
Description
technical field [0001] The invention belongs to the technical field of electric vehicle charging piles, and in particular relates to a vehicle spatial positioning system and a method for judging its validity. Background technique [0002] The charging equipment located on the vehicle needs to be parked in the charging area of the charging equipment when the vehicle is parked. It is required in the horizontal, front, rear, left and right directions. At present, the front and rear positioning is mainly completed through the speed bump, and the left and right depends on the driver's feeling. , but there is no detection ability after parking, and it can only be confirmed by whether the electrical connection can be completed after the charging equipment is connected. detection and redundancy. SUMMARY OF THE INVENTION [0003] The invention mainly solves the terminal positioning problem in the spatial positioning problem, helps the driver to accurately park in the charging ar...
