Abstract

Provided is a testing system for a drivetrain, the testing system capable of simulating the slip behavior of a tire. A testing system is provided with: tire speed calculation units; a vehicle speed calculation unit; vehicle driving torque calculation units which calculate vehicle driving torque values; and speed control devices which output command signals such that the deviations between command values and output values from encoders are eliminated, respectively. The tire speed calculation units calculate the tire speed values on the basis of tire driving torque values obtained by subtracting the vehicle driving torque values from output values from shaft torque meters, respectively, and the vehicle speed calculation unit calculates the vehicle speed value on the basis of the vehicle driving torque values.
