摘要： To obtain vehicle speed deviation data for changeover between accelerator and brake properly with inclination of a standard mode. In technique of calculating a changeover vehicle speed deviation from accelerator to brake in driving vehicle along standard mode (target vehicle speed) of vehicle drive pattern defined by time and vehicle speed within range of predetermined vehicle speed and time deviations from standard mode, an inclination AB of the standard mode is calculated by approximate differentiation of vehicle speed at a judgment standard point A of a current time instant on standard mode, first inclination AB is multiplied by an accelerator-to-brake changeover time deviation preset value Δt−1, and the accelerator-to-brake changeover vehicle speed deviation from the judgment standard point A to a changeover judgment point E for changeover at the current time instant is calculated by addition of the product and an accelerator-to-brake changeover vehicle speed deviation preset value ΔV−1.

摘要： The purpose of the present invention is to provide a drive train testing system whereby torque fluctuation in a real engine can be reproduced with good precision. A drive train testing system is provided with an input-side dynamometer connected to an input shaft WI of a test piece W which is a vehicle drive train, a torque command generation device for generating a torque command signal for causing a torque resembling that of a vehicle engine to be generated by the input-side dynamometer, and a rotation detector for detecting a motor machine angle corresponding to an absolute position from a reference position of a rotary shaft of the input-side dynamometer. Using the motor machine angle detected by the rotation detector, the torque command generation device generates a torque command signal fluctuating in synchrony with a signal having a period that is a predetermined degree multiple of the motor machine angle.
