The invention provides a positioning method and system based on an automobile key and an unmanned automobile system. The positioning method comprises the steps of setting a GPS device and an inertialnavigation device in the automobile key; obtaining the current GPS signal intensity; if the current GPS signal intensity is greater than a first threshold, obtaining current positioning information byusing the GPS device; if the current GPS signal intensity is between the first threshold and a second threshold, obtaining the current positioning information by using the GPS device, and modifying current positioning information obtained by the inertial navigation device by using the current positioning information obtained by the GPS device, wherein the second threshold is less than the first threshold; and if the current GPS signal intensity is less than the second threshold, obtaining the current positioning information by using the inertial navigation device. According to the positioningmethod and system based on the automobile key and the unmanned automobile system, accurate positioning is realized on the automobile key based on a mode of integrating GPS positioning and inertial navigation positioning, so that accurate positioning information is provided for an unmanned automobile.
Description
technical field [0001] The present invention relates to a positioning method and system, in particular to a vehicle key-based positioning method and system, and an unmanned vehicle system. Background technique [0002] Since the 1970s, developed countries such as the United States, the United Kingdom, and Germany have begun research on unmanned vehicles, and have made breakthroughs in feasibility and practicality. China began research on unmanned vehicles in the 1980s, and successfully developed China's first truly unmanned vehicle in 1992. [0003] A driverless car is a smart car that senses the road environment through the on-board sensor system, and automatically plans the driving route and controls the steering and speed of the vehicle based on the road, vehicle position and obstacle information obtained from the perception, and finally reaches the intended target. [0004] In the actual application scenario, the car owner sends his current location information to the d...
