TESTING SYSTEM AND METHOD FOR AUTOMOTIVE COMPONENT USING DYNAMOMETER
First Claim
1. A testing system for an automotive vehicular component, comprising:
- a dynamometer linked to the vehicular component to be tested via a torque meter and a rotary shaft, the dynamometer being controlled by means of an inverter;
a servo driver;
an electronic controlling section, the vehicular component to be tested being controlled by outputs of the servo driver and electronic controlling section;
a system monitor section that monitors and sets required items including a vehicular specification and a running resistance of the vehicle and outputs required items including the vehicular specification and the running resistance to a measurement controlling section;
a model generating section connected to the system monitor section via a transmission path and in which a simulation model including a vehicular vertical vibration model constituted by a vehicular suspension spring and a tire spring and a spring model of an inertia system is set; and
a vehicular model execution controlling section that executes a vehicular model simulation for the vehicular component to be tested by introducing at least an acceleration signal and a clutch signal from the measurement controlling section and the simulation model from the model generating section and outputs control signals to the inverter and the electronic control section so as to control the vehicular component to be tested.

Abstract
In testing system and method for an automotive vehicular component such as an engine, a system monitor section sets required items including a vehicular specification and a running resistance of the vehicle and outputs the set required items to a measurement controlling section, a model generating section is provided in which a simulation model including a vehicular vertical vibration model constituted by a vehicular suspension spring and a tire spring and a spring model of an inertia system is set, a vehicular model execution controlling section executes a vehicular model simulation for the vehicular component to be tested by introducing at least an acceleration signal and a clutch signal from the measurement controlling section and the simulation model from the model generating section and outputs control signals to the inverter and the electronic control section so as to control the vehicular component to be tested.
