초록 ▼

The components of a vehicle, in particular of a non-rail vehicle, which is powered by an electric motor traction propulsion system, can be protected against the damaging effects of accelerations which occur during operation by reducing the operating power supplied to a propulsion motor of the vehicle when the accelerations which occur on certain components of the vehicle reach values which pose an immediate danger to these components or reduce their useful life. For this purpose, a traction propulsion system which includes at least one electric motor, a power supply device which supplies the electric motor with operating power and an electronic switching system to control the operating power supplied to the electric motor is equipped with acceleration sensor means and with evaluation means, whereby the acceleration sensor means supply at least one variable which is a function of the acceleration of at least one component of the vehicle, and the evaluation means respond to this variable and control the electronic switching system so that at least in a portion of the range of values of the acceleration-dependent variable, the operating power supplied to the electric motor is reduced in accordance with a specified characteristic.
