Problems solved by technology

However, the existing parking lot guidance technology has many deficiencies: First, the existing parking lot guidance technology guides the driver to park, and has not considered directly guiding the driverless car to park, requiring the driver to drive into the parking lot by himself. Carry out parking operations; sec...

Embodiment Construction

[0062] The parking lot entrance guidance system for unmanned vehicles provided by the present invention includes a mobile internet client, a vehicle guidance cloud platform, an on-board unit installed on the guided vehicle, a barrier at the entrance of the parking lot, and an image information collection device.

[0063] The self-driving car parking lot entrance guidance method provided by the present invention comprises the following steps:

[0064] 1. The vehicle guidance system confirms and judges whether the status of the parking lot and the guided vehicle meet the triggering conditions of the system in turn.

[0065] 2. The vehicle guidance cloud platform obtains the image information of the guided vehicle, processes the image information, and obtains visual features; and uses this visual feature to compare with the preset HAD-level high-precision map and map-associated visual feature library, so as to perform real-time high-precision Precision positioning. The high-prec...

Abstract

The invention discloses a parking lot entrance guide system of a driverless vehicle and a guide method using the system. The guide system comprises a mobile internet client terminal, a vehicle guide cloud platform, a vehicle-mounted unit arranged on a guided vehicle, a barrier gate and an image information collection device, wherein the barrier gate and the image information collection device are arranged at a parking lot entrance. The guide method comprises the following steps: triggering the guide system; determining a vehicle initial state of the guided vehicle via the vehicle guide cloud platform; calculating vehicle control parameters; carrying out vehicle control and simultaneously carrying out on-line simulation of vehicle driving via the vehicle guide cloud platform; carrying out an interrupt operation when an interrupt condition is triggered, or performing the next step; and exiting guide when an ending condition is achieved.

Description

technical field [0001] The present invention relates to the technical field of intelligent vehicles, in particular to an unmanned vehicle parking lot entrance guidance system and a guidance method using the system. Background technique [0002] "Electrification, intelligence, and networking" are the future development directions of automobiles; among them, unmanned driving is an important application of intelligent networked vehicles. In the unmanned driving scenario, the automatic parking system is an important function of the unmanned smart car. This function is designed to enable the vehicle to find a suitable parking space and park without manual intervention by the driver. Existing parking schemes only provide the functions for cars to search for parking spaces in a small area, and to park in and out. This small-scale automatic parking function solves a series of problems such as parking by unskilled drivers and precise parking in small-sized parking spaces. However,...
