Problems solved by technology

Among them, the UWB module is the main part of the cost of the anchor station. In order to meet the positioning requirements in the area around the vehicle and inside the vehicle, it is necessary to install the same number of UWB modules as the number of anchor point antennas, which is expensive.

Abstract

The invention relates to the technical field of vehicle communication, in particular to a vehicle-mounted positioning assembly, method, device and equipment based on an ultra wide band (UWB), the assembly comprises at least one UWB module and a plurality of anchor antennas, and the anchor antennas are arranged in preset installation areas of a vehicle body in a grouped mode. The signal areas of the plurality of anchor point antennas cover a preset area around the vehicle and / or in the vehicle, and the output end of the at least one ultra wide band (UWB) module is connected with two or more anchor point antennas which are located at different positions and / or have different directions in a time-sharing manner. According to the invention, on the basis of setting the same number of anchor antennas, the installation amount of the UWB module is reduced, the effective use time of the single UWB module is prolonged, and the production and use cost is reduced.

Description

technical field [0001] The present disclosure relates to the technical field of vehicle communication, and in particular to a UWB-based vehicle positioning component, method, device and equipment. Background technique [0002] Ultra Wide Band (UWB) technology is a carrier-free communication technology. It does not use sinusoidal carrier, but uses nanosecond-level non-sinusoidal narrow pulse to transmit data. Its signal peak is steep and narrow, even in noisy It is also easy to identify in a multi-channel environment. Therefore, it can meet the needs of various short-range wireless communication, especially suitable for precise positioning of dense multi-path places, such as vehicle unlocking, vehicle automatic start, vehicle passenger detection, vehicle drone operation, automatic valet parking, Automated parking, parking lot entry, drive-through payments and more. The anchor station in the current vehicle-mounted UWB system consists of a UWB module and a positioning anchor...
