On-road driving test evaluation method, vehicle test system, and computer readable storage medium for an on-road driving test evaluation program

A vehicle test system which evaluates an on-road driving test by conducting a bench test of a test subject which is an actual vehicle or a part thereof, comprising:

• a simulation device that simulates the on-road driving test using a driving environment model which models a driving environment, an operating state model which models an operating state, and a vehicle model which models the actual vehicle;
• a first bench test device which imitates the on-road driving test by combining a part or all of the actual vehicle including an engine or a motor, a part or all of the vehicle model, a part or all of the driving environment model, and a part or all of the operating state model, and conducting a bench test of the part of the actual vehicle including the engine or the motor;
• a second bench test device which imitates the on-road driving test by combining the actual vehicle, the part or all of the driving environment model, and the part or all of the operating state model, and conducting a bench test of the actual vehicle;
• and
• a higher-level management device, including a CPU, an internal memory, and an input-output interface, which controls the first bench test device and the second bench test device to imitate the on-road driving test, wherein
• the first bench test device is configured to, under control of the higher-level management device, provide feedback to the simulation device to make an evaluation result of the vehicle model used in simulation match an evaluation result of the part of the actual vehicle including the engine or the motor used by the first bench test device, or
• the second bench test device is configured to, under control of the higher-level management device, provide feedback to the first bench test device to make an evaluation result of the part of the actual vehicle including the engine or the motor used by the first bench test device match an evaluation result of the actual vehicle used by the second bench test device.

An on-road driving test evaluation method that evaluates an on-road driving test by conducting a bench test of a test subject which is an actual vehicle or a part thereof, comprising:

• a virtual evaluation step of simulating the on-road driving test using a driving environment model which models a driving environment, an operating state model which models an operating state, and a vehicle model which models the actual vehicle;
• a bench test evaluation step of imitating the on-road driving test by combining a part or all of the actual vehicle, a part or all of the vehicle model, a part or all of the driving environment model, and a part or all of the operating state model, and conducting a bench test of the part or all of the actual vehicle;
• an on-road driving test evaluation step of conducting the on-road driving test of the actual vehicle in a real driving environment;
• a comparison step of comparing an evaluation result of the part or all of the actual vehicle in the bench test evaluation step with an evaluation result of the vehicle model in the virtual evaluation step, or comparing an evaluation result of the actual vehicle in the on-road driving test evaluation step with an evaluation result of the part or all of the actual vehicle in the bench test evaluation step;
• and
• a feedback step of providing feedback to the virtual evaluation step to make an evaluation result of the vehicle model in the virtual evaluation step match an evaluation result of the part or all of the actual vehicle in the bench test evaluation step, or providing feedback to the bench test evaluation step to make an evaluation result of the part or all of the actual vehicle in the bench test evaluation step match an evaluation result of the actual vehicle in the on-road driving test evaluation step.
