Embodiment Construction

[0048] The solutions in the embodiments provided in the present application will be described below with reference to the drawings in the present application.

[0049] The terms "first" and "second" in the embodiments of the present application are used for description purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of indicated technical features. Thus, a feature defined as "first" and "second" may explicitly or implicitly include one or more of these features.

[0050] First, some technical terms involved in the embodiments of the present application are introduced.

[0051] Radar (Rader) refers to electronic equipment that uses electromagnetic waves or mechanical waves for detection and ranging. The radar emits electromagnetic waves or mechanical waves to irradiate the target and receives its echo, thereby obtaining the distance, speed change rate, azimuth, and height from the target to the launch p...

Abstract

The invention provides a radar parameter configuration method, which comprises the following steps: acquiring an environmental parameter of an environment where a radar is located currently, and determining a calibration value of a target parameter corresponding to the environmental parameter according to a parameter table obtained by calibrating the radar in different environments, and finally, configuring the target parameter according to the calibration value of the target parameter. Therefore, the radar can configure parameters according to the environment, the radar sensitivity is prevented from being influenced by the environment, and the detection performance of the radar is further prevented from being influenced.

Description

technical field [0001] The present application relates to the field of automotive electronics, in particular to a radar parameter configuration method, device and vehicle. Background technique [0002] Radar, as an extremely common sensor, not only has a wide range of applications in helping drivers reversing, but also, with the gradual maturity of intelligent driving technology, radar, especially vehicle-mounted ultrasonic radar, has a wider application space. [0003] However, the sensitivity of some radars such as ultrasonic radars is easily affected by the environment. For example, if the same ultrasonic radar hardware is configured with the same parameters, when the temperature is high, the detection capability of the ultrasonic radar is reduced, the detection range is small, and the sensitivity is low; when the temperature is low, the detection capability is improved, and the detection range is large. Higher sensitivity. This situation will affect the performance of ...
