Description

technical field [0001] The embodiments of the present invention relate to the technical field of vehicles, and in particular to a distance detection method, device and vehicle. Background technique [0002] During the parking process of the vehicle, accurately identifying the limit rod in the parking space, and accurately detecting the distance of the limit rod can better control the parking vehicle. At present, the commonly used method is to identify and locate the limit rod through ultrasonic radar signals, but due to the installation position of the limit rod, the ultrasonic radar signal cannot accurately identify the limit rod, and the distance error of the detected limit rod is relatively small. Big. Therefore, how to accurately detect the distance between the vehicle and the limit rod has become an urgent problem to be solved. Contents of the invention [0003] Embodiments of the present invention provide a distance detection method, device and vehicle to solve the...
