Title:
DESIGN ASSISTANCE METHOD, DESIGN ASSISTANCE SYSTEM, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/090004
Kind Code:
A1
Abstract:
Provided are a design assistance method, a design assistance system, and a program with which it is possible to design an ODD that suppresses an increase in the cost of developing automated driving services and improves key performance indicators of business proprietors. This design assistance system acquires environmental data from an environmental measurement device for measuring the environment of a service provision area managed by a customer, and customer requirements, and outputs improved values of key performance indicators of the customer. This design assistance system is characterized by comprising: an automated driving control function database that stores programs for performing automated driving control of a vehicle traveling in the service provision area; an area environmental data generation unit that is provided with an area digital map generation unit for generating a digital map of the service provision area using the environmental data; an automated driving ODD automatic definition unit that generates and outputs an operational design domain, which constitutes environmental constraint conditions for operating an automated driving service, from information about the digital map; an ODD adjustment unit that evaluates the sufficiency of the automated driving control function specifications stored in pairs in an automated driving control program, with respect to the operational design domain output from the automated driving ODD automatic definition unit, and changes the operational design domain on the basis of the evaluation result; an automated driving control system evaluation unit that evaluates the operational design domain on the basis of the customer requirements; and a KPI evaluation unit that generates a customer requirement evaluation formula for evaluating the customer's key performance indicators, on the basis of the customer requirements, calculates the customer requirement evaluation formula on the basis of the value output from the automated driving control system evaluation unit, and outputs the operational design domain and the customer's key performance indicators. This design assistance system is further characterized in that: the ODD adjustment unit changes the operational design domain on the basis of the value of the customer requirement evaluation formula calculated and output by the KPI evaluation unit, so as to improve the value of the customer requirement evaluation formula; and the KPI evaluation unit outputs improved values of the customer's key performance indicators on the basis of the changed operational design domain.
