Abstract

Provided is a testing system which is able to reproduce road surfaces in different states between both right and left tires. A testing system is provided with: a tire speed calculation unit which calculates virtual left and right tire speed values; a vehicle speed calculation unit which calculates a virtual vehicle speed value; a vehicle drive torque calculation unit which calculates left and right vehicle drive torque values; a differential torque calculation unit which calculates left and right differential torque values; and a speed control device which outputs a torque current command signal such that a deviation between a speed command value and a value detected by an encoder is eliminated. The tire speed calculation unit calculates the tire speed value on the basis of the differential torque values and the vehicle drive torque values.
