Accelerate as in When the rotational speed of the electric motor DM reaches a predetermined value (time point 1 in the figure), the electric motor DMi is turned off and controlled by the brake BR. During this control, motor D
M was controlled by applying braking torque energy from the flywheel FW as shown by the speed decreasing curve n8 shown in FIG. 2 with the driving force being zero.

ーキＢＲに負荷出来ないために下シ坂試験が出来ない欠
点があった。The above control operation is performed only when the vehicle is running on a flat road; in fact, the brakes are often operated even when driving down a slope. However, with the configuration shown in Fig. 1, the drive motor DM cannot have the driving force when operating the brake, and the output of the speed control circuit ASR cannot load the brake BR with a single torque. There was a drawback that the lower slope test could not be performed because there was no such thing.
この発明は上記の欠点を除去し、車両の下シ坂試験のみ
ならず、上シ坂試験もできるようにしたブレーキダイナ
モメータ全提供することを目的とする。The object of the present invention is to eliminate the above-mentioned drawbacks and to provide a brake dynamometer that can perform not only a downward slope test of a vehicle but also an upward slope test.
以下、図面を参照してこの発明の一実施例全説明する。Hereinafter, one embodiment of the present invention will be fully described with reference to the drawings.

される。In FIG. 3, the same parts as in FIG. 1 are given the same reference numerals, and the explanation thereof will be omitted. In the following description, the torque of the electric drive mDM is detected by an electric-torque detection circuit TD. The output of this detection circuit TD is supplied to the matching circuit OMl together with the output of the torque setting device T. The output of the butt N path OMl is input to the t reduction control circuit AOR via the torque control circuit ATR. Furthermore, II! r3) The output of the torque control circuit ATH is not directly input to the current control circuit MOR, but is selected by a changeover switch SW inserted in the electrical circuit between the speed control circuit ABR and the current control circuit AOR. is input.

ったままとする。In the embodiment configured as described above, the drive motor DMt is accelerated by the output of the speed control circuit MSH as shown in the speed increase curve n1 in FIG. 4 as in FIG. 1. Electric motor D
It is assumed that the number of identical rotations of M reaches a predetermined value at time 11 shown in the figure. At this time, the changeover switch sw'1 is connected to the ATR side from the illustrated position, and the electric motor DM is kept in the on state.

ケンス制御にょシ通常の平坦路試験も可能となる。Then, the torque output of the torque control circuit ATR controls the driving mechanism DM. On the other hand, at the time tl, the brake BR is also turned on, but as a brake, a constant torque is added in addition to the inertia torque from the flywheel FW, as well as the torque from the output of the torque control circuit ATR, so that the vehicle is lower than the actual It becomes possible to perform a downward slope test, which is the same as when going down a slope. Furthermore, if the absorption torque is set in the drive motor DM, an uphill slope test can be performed, and furthermore, a normal flat road test can be performed using sequence control.

点がある。As described above, since the present invention detects the torque of the first drive motor and adds inertia torque to this detected torque, braking tests not only on downhill slopes but also on uphill slopes can be performed on actual driving roads. It has the advantage that it can be done in the same way.
