Patent ID: 7222507

Claim:
A system for determining quantities which influence the operating dynamics of a motor vehicle in the absence of hazardous driving states, comprising: a plurality of actuators; at least two different regulating/control arrangements, each of which is configured to, independently of one another and independently of the driver, use at least one of the actuators to carry out an intervention to influence the vehicle operating dynamics and to alter a same quantity which describes the vehicle dynamics; a control arrangement configured to cause two of these different regulating/control arrangements to implement corresponding interventions, each tending to cause the same quantity which describes the vehicle dynamics to be altered in an offsetting manner so that, as a result of a combination of the corresponding interventions, the same quantity is not altered or is altered as little as possible by the corresponding interventions; and an arrangement for determining, based on the same quantity, one or more quantities which influence the operating dynamics; wherein the one or more quantities which influence the operating dynamics include at least one of wheel loads, brake characteristic curves, tire characteristic curves, steering characteristic quantities, adhesion coefficients and inflatable-space-tire recognition.
