Obstacle detection method, vehicle control method, vehicle and storage medium

Abstract

The invention relates to the technical field of radar detection, and discloses an obstacle detection method, a vehicle control method, a vehicle and a storage medium, and the obstacle detection method comprises the steps: obtaining vehicle position information, and determining a driving scene where the vehicle is located according to the vehicle position information and map information; and / or acquiring surrounding environment information of the vehicle, and determining a driving scene where the vehicle is located according to the surrounding environment information; when the driving scene is a preset scene, starting an ultra-wideband detection mode, and in the ultra-wideband detection mode, sending ultra-wideband detection waves and receiving echoes of the ultra-wideband detection waves; and if the frequency of the echo changes within a period of time, determining that a moving object exists behind the obstacle. Therefore, the moving object behind the obstacle is detected, and the power consumption of the ultra-wideband positioning device is reduced.

Description

technical field [0001] The invention relates to the technical field of radar detection, in particular to an obstacle detection method, a vehicle control method, a vehicle and a storage medium. Background technique [0002] Generally, when vehicles pass through narrow intersections, alleys, and vehicles parked on the sidewalk, obstacles are identified through the sensors used for environmental recognition on the car. The sensors mainly include cameras and radars. The radar is divided into Millimeter-wave radar, lidar, and ultrasonic radar use these sensors to identify the surrounding environment of the vehicle, obstacles, etc., as input for obstacle avoidance and warning functions, and display it on the host screen for reference to vehicle owners. [0003] However, in the actual driving process of the vehicle, pedestrians, pets, and vehicles, etc. are often encountered suddenly and quickly traverse from the blind spot of the field of view, which brings great safety hazards to...

Problems solved by technology

[0003] However, in the actual driving process of vehicles, pedestrians, pets and vehicles that suddenly cross quickly from the blind spot of vision are often encountered, which brings great safety hazards to vehicles and drivers.

At present, the sensors equipped on vehicles are mainly cameras, millimeter-wave radars and lidars, and there are detection blind spots, so the driving safety of drivers cannot be guaranteed more effectively.
