AI Technical Summary

Technical Problem

The existing on-board assisted driving functions are difficult to effectively identify and display close-range obstacles in scenarios such as narrow parking spaces, narrow road traffic, narrow road turnover, narrow road car meetings, etc., resulting in insufficient driver safety assistance capabilities.

Method used

By integrating multiple sensors on the vehicle, such as cameras, lidars and millimeter wave radars, multimodal perception information is obtained, combined with a perception prediction network, it generates occupancy grid pictures of different grid particle sizes, displays the distribution of obstacles around the vehicle, and provides panoramic and refined perception.

Benefits of technology

It improves the driver's perception of obstacles at large range and close range, helps the driver avoid scratches, and improves the safety and operation convenience of the vehicle in complex scenarios.

Abstract

An assisted driving method and apparatus. The assisted driving method comprises: acquiring multi-modal perception information, wherein the multi-modal perception information is collected by a plurality of sensors provided in a vehicle (100); acquiring a plurality of groups of display information, wherein the display information comprises target areas to be displayed and grid granularities; performing perception prediction on the basis of the multi-modal perception information and the plurality of groups of display information, so as to obtain a plurality of pieces of occupancy grid information, wherein the occupancy grid information is used for describing the distribution of obstacles around the vehicle (100); and displaying a plurality of occupancy grid pictures on a human-computer interaction interface on the basis of the plurality of pieces of occupancy grid information. By means of the present application, not only can the panoramic perception capability of a driver for obstacles within a large range be improved, but the refined perception capability of the driver for obstacles within a short-distance range can also be improved, and the perception capability of the driver for surrounding environments can be improved by means of a combination of the panoramic perception capability and the refined perception capability, thereby avoiding scratching.
