Abstract

The invention relates to an optimization configuration method for an automobile driving assistance system sensor. The method is performed on an environmental perception sensor. The method comprises the following steps of performing a uniform description on environmental information perception of a driving assistance system based on a typical application scene; establishing a multi-dimensional comprehensive evaluation model of a sensor system; establishing a sensor perception function model; and performing a screening optimization process on an alternative sensor and an alternative installationposition by use of a global search algorithm. According to the optimization configuration method for the automobile driving assistance system sensor, the screening optimization and configuration optimization of a key sensor in the automobile driving assistance system are realized by use of a computer-optimized solution method, and the problem of optimization configuration of the key sensor in a complicated part supply system is solved.

Description

technical field [0001] The invention relates to a preferred configuration method for sensors of an automobile driving assistance system, in particular pointing out a method for screening and optimization and configuration optimization of environmental perception sensors for the automobile driving assistance system. Background technique [0002] Environmental perception sensors are an important part of automotive driving assistance systems. They are mainly used to perceive the traffic environment, detect and identify surrounding traffic participants and traffic signs, etc., including millimeter wave radar, laser radar, ultrasonic radar and visual sensors. With the continuous improvement of people's demand for car driving assistance functions, more and more sensors are integrated on the car, and the environmental perception system is becoming more and more complex. The traditional method of superimposing integration or relying on experience configuration will easily lead to str...
