Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are only used to explain the present invention, and do not constitute a limitation to the protection scope of the present invention.

[0019] see figure 1 , figure 2 The method for reducing the false trigger rate of vehicle active safety described in this embodiment includes: detecting the environmental conditions through the radar and camera on the vehicle, wherein the radar is responsible for identifying information such as the distance and speed of the target ahead, and the camera is responsible for identifying the shape of the target ahead , location and other information. After radar preprocessing and machine vision analysis, the forward target information is sent to the active safety controller. The active safety controller first performs "sensor information fusion" to judge the status of the target ahead (including ...

Abstract

The invention discloses a method for reducing the false trigger rate of vehicle active safety, which is to detect the environmental conditions through active safety sensors, and judge whether the intervention of the active safety system is needed; the real-time position information of the vehicle is transmitted to the remote service information platform, according to The location information is queried from the data storage unit to obtain the correct trigger probability and wrong trigger probability of the active safety here, and feed back the two probabilities to the vehicle; when the active safety system needs to intervene, the vehicle active safety controller Correct the comparison threshold for error trigger probability, compare the corrected threshold with sensor detection data, and comprehensively judge whether the active safety system is allowed to execute; at the same time, return the execution result of the active safety system to the remote service information platform to recalculate the probability And update the result to the data storage unit.

Description

technical field [0001] The invention relates to the technical field of automobile active safety, in particular to a method for reducing the false trigger rate of vehicle active safety. Background technique [0002] With the development of the automobile industry, the focus of people's attention is more and more concentrated on how to reduce the potential safety hazard of vehicles. As a result, active safety has increasingly become the main direction of the development of the automobile industry. Different from passive safety, active safety technology mainly uses specific technologies (including sensor technology, signal processing technology, communication technology, and computer technology) to identify the environment in which the vehicle is located. And the state, and make analysis and judgment based on the information obtained by each sensor, help the driver to control the vehicle in advance, so that the car can actively avoid danger, thereby reducing traffic accidents a...
