Title:
SENSING PERFORMANCE EVALUATION AND DIAGNOSIS SYSTEM AND SENSING PERFORMANCE EVALUATION AND DIAGNOSIS METHOD FOR EXTERNAL ENVIRONMENT RECOGNITION SENSOR
Document Type and Number:
WIPO Patent Application WO/2021/006262
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a sensing performance evaluation and diagnosis system with which a malfunction predictor of an external environment recognition sensor being diagnosed can be detected by comparing the output of the external environment recognition sensor being diagnosed and the output of an external environment recognition sensor serving as a reference, without relying on reference information registered in advance in a map. The sensing performance evaluation and diagnosis system is characterized by being equipped with: a sensing data acquisition unit for acquiring sensing data for the periphery of a host vehicle from observation values of an external environment sensor that is mounted on the host vehicle and is to be diagnosed; a periphery information acquisition unit for acquiring periphery information data about the periphery of the host vehicle from observation values of a reference external environment sensor; a reference value calculation unit for generating reference value data on the basis of a recognition history of relative information with respect to a reference object included in the periphery information data; and an evaluation unit for comparing the sensing data pertaining to the reference object to a threshold value that has been set for the reference value data, and thereby evaluating whether the performance of the external environment sensor being diagnosed has deteriorated or evaluating a degree of deterioration in the performance.
