Zusammenfassung:	The disclosure describes a safety device for a chassis dynamometer in which a signal representative of the speed of rotation of the dynamometer's rollers is processed to give a signal representative of the temperature of the tires of a vehicle being tested on the dynamometer. The signal is dependent on the time integral of Sx where x is approximately 3 and S represents the speed of a dynamometer roller. When the temperature representative signal reaches a predetermined maximum safe value, an alarm is triggered.
