First Claim
1. A tester for simulating characteristics of a vehicle incorporating a subsystem under test, the tester comprising:
- at least one test rig actuator configured to apply a test condition to the subsystem;
at least one sensor configured to collect signals related to the subsystem;
a data processing system including;
a data processor for processing data; and
a data storage device configured to store machine-executable instructions and data related to a simulation model representing the vehicle not including the subsystem, wherein the instructions, upon executed by the data processor, control the data processing system to perform the steps of;
generating a set of test signals based on the simulation model;
controlling the at least one test rig actuator to apply a test condition to the subsystem based on the test signals;
obtaining a response of the subsystem to the applied test conditions;
calculating effects of the subsystem to the vehicle using the simulation model incorporating information related to the response of the subsystem to the applied test condition; and
generating a result of the calculated effects.

Abstract
A vehicle tester using integrated simulation model and physical parts under test for determining effects of the physical parts to a complete vehicle incorporating the parts. A simulation model representing the vehicle excluding the physical parts is provided. A test scenario is applied to the simulation model. The response of the simulation model is translated to a test condition applying to the physical parts under test, to obtain the physical parts response to the test condition in real time. Responses and changes occurred on the parts under test are dynamically obtained and incorporated into a calculation of the effects of the physical parts to the vehicle using the simulation model. A report of the calculated effects is then generated.
