Zusammenfassung:	The disclosure describes a chassis dynamometer provided with control means which may be activated so as to maintain the acceleration of the dynamometer rollers at a predetermined constant positive or negative value. Means are provided to multiply the braking torque absorbed by the dynamometer by the speed of rotation of the idle roller and to add to the product a signal proportional to the speed of rotation of the rollers so as to maintain a signal substantially proportional to the traction power output of the vehicle being tested while accelerating or decelerating at the predetermined constant value.
