PURPOSE:To execute brake tests in not only a descent but also an ascent in the same manner as an actual travelling path by detecting the torque of a driving motor and adding the torque of inertia to the detecting torque. CONSTITUTION:The torque of the driving motor DM is detected by an electric- torque detecting circuit TD. An output signal from the detecting circuit TD and a torque set value T are inputted to a torque control circuit ATR. The driving motor DM is accelerated by an output from a speed control circuit ASR. When the number of revolution reaches a fixed value, a changeover switch SW is connected to the circuit ATR side, and the motor DM is controlled by a torque output from the circuit ATR.. A brake BR is also applied at that time, but the test in the descent made the same as the case when a car falls on an actual descent is enabled because fixed torque is added. When absorption torque is set to the motor DM, the test in the ascent is also enabled. |
