Road obstacle detection method based on detection radar, vehicle and storage medium

Abstract

The invention discloses a road surface obstacle detection method based on detection radar, a vehicle and a storage medium, the method is applied to the vehicle, the vehicle is provided with a plurality of radar antennas forming a preset included angle, and the road surface obstacle detection method comprises the following steps: according to a preset time division scanning strategy, periodically transmitting detection beams in different scanning directions in sequence in the driving direction of the vehicle based on the plurality of radar antennas; and receiving reflection beams reflected back in different scanning directions, and determining the obstacle type of the road obstacle in the driving direction according to the reflection beams. According to the invention, the driving safety of the vehicle using the Doppler radar to carry out road obstacle detection is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle obstacle detection, in particular to a detection radar-based road obstacle detection method, a vehicle and a storage medium. Background technique [0002] Automated driving technology has increasingly become the hotspot and core technology of smart car technology. Obstacle detection and recognition are the prerequisites for automated driving, and Doppler radar detection technology has gradually become the mainstream technology for identifying obstacles ahead of the vehicle. [0003] At present, the Doppler radar system applied to vehicles generally scans in the horizontal direction. When a vehicle equipped with a Doppler radar detection system turns on automatic assisted driving, when facing an obstacle type with a blank bottom and an obstacle at a certain height in front, it often misjudges that the front is a safe space, resulting in a vehicle collision safety incidents. For example, there is ...

When a vehicle equipped with a Doppler radar detection system turns on automatic assisted driving, when facing an obstacle type with a blank bottom and an obstacle at a certain height in front, it often misjudges that the front is a safe space, resulting in a vehicle collision of security incidents

For example, there is a horizontal height-restricted arch in front, and the height of the vehicle is higher than the height-restricted arch. However, since the area under the height-restricted arch is empty, the Doppler radar installed at a lower level cannot be scanned by the beam scanning in the horizontal direction. On the height limit body of the high arch, at this time, the vehicle will misjudge that the front is a safe space, resulting in a collision accident

[0004] Existing vehicles equipped with Doppler radar detection systems have serious safety hazards, how to improve the safety of Doppler radar detection has become an urgent problem to be solved
