Abstract
A method and a system for recongnizing both a driving-dynamic state of a vehicle and a surface quality of the carriageway of which the vehicle is moving. The pressures of the tires of the vehicle are measured and evaluated so that conclusions can be draw on both current driving-dynamic states and existing surface qualities of the carriageway.
Claims23
Method for recognizing driving-dynamic states of a vehicle, with the following steps:
- isochronous measurement of respectively one reference pressure for each of at least two tires of the vehicle,
- isochronous measurement of respectively one current pressure for each of the at least two tires,
- comparison of the reference pressure of the at least two tires with, respectively, the corresponding current measured pressure, for the purpose of determining a variation of the pressure for each of the at least two tires,
- comparison of the pressure variations of the at least two tires, and
- evaluation of the determined pressure variations of the at least two tires and of the comparison of the same, for the purpose of generating driving state information which indicates the driving-dynamic state of the vehicle.
2 more elements
System for recognizing driving-dynamic states of a vehicle, comprising:
- pressure sensors which are respectively arranged for the purpose of measuring tire pressures of at least two tires of the vehicle, and
- a processor unit which is connected to the pressure sensors and receives and evaluates signals from the pressure sensors which respectively indicate the pressures measured by the corresponding pressure sensor, characterized in that
- driving state signals generated by the processor unit on the basis of the signals of the pressure sensors indicate a driving-dynamic state of the vehicle.
