Embodiment Construction

[0075] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with this disclosure.

[0076] Existing self-driving vehicles are deployed with various types of sensors. In order to ensure the quality of the self-driving vehicle, the sensors need to be calibrated before the self-driving vehicle leaves the factory to ensure the normal functions of the sensors. But in the process of calibrating the sensor, there are many problems.

[0077] In one example, most of the calibration engineering software is based on the use of CANoe engineering provided by the car factory supplier or original equipment manufacturer (Original Equipment M...

Abstract

The invention provides an off-line calibration processing method, device and equipment based on an automatic driving vehicle, and relates to the automobile software technology, and the method comprises the steps: obtaining a calibration command which is inputted by a user and aims at each to-be-calibrated sensor in a plurality of types of to-be-calibrated sensors; packaging the calibration command according to preset calibration process information to obtain a calibration electric signal; wherein the calibration process information is used for indicating calibration logic information and calibration function information, the calibration logic information represents calibration steps corresponding to calibration processing categories and calibration parameters, and the calibration function information represents safety steps corresponding to the sensor to be calibrated. And inputting the calibration electric signal into a to-be-calibrated sensor connected with the electronic equipment, and receiving calibration result information returned by the to-be-calibrated sensor. According to the method provided by the invention, the calibration processing operation is relatively rapid, errors are easy to check, and the technical problem that the offline calibration operation efficiency of the automatic driving vehicle is relatively slow is solved.

Description

technical field [0001] The present application relates to automotive software technology, and in particular, to an offline calibration processing method, device and device based on an autonomous vehicle. Background technique [0002] At present, before the self-driving vehicle leaves the factory, the whole vehicle of the self-driving vehicle needs to be calibrated offline. [0003] In the prior art, during the off-line calibration process of the complete vehicle of the autonomous driving vehicle, various functions of the sensors in the autonomous driving vehicle may be manually calibrated item by item to obtain a data calibration result. [0004] However, in the prior art, the manual calibration method requires personnel to require relatively high skills, which is prone to the problem of calibration errors; and the manual calibration method has a slow processing speed and low efficiency. SUMMARY OF THE INVENTION [0005] The present application provides a processing metho...
