Abstract
A method for determining the load of a motor vehicle includes the following steps: detecting at least one physical measured variable that depends on the load and generating a measured value that represents the detected measured variable; evaluating the generated measured values in order to determine the load by correlating the generated measured values or the load values determined therefrom with each other in order to produce a correction value from the correlation, with the aid of which an actual load value is determined for the load of the motor vehicle. There is also provided a system for detecting the load of a motor vehicle, and a motor vehicle.
Claims13
A method of determining a load of a motor vehicle, the method which comprises:
- detecting at least one given physical measured variable which is dependent on the load of the motor vehicle, the physical measured variable representing a parameter selected from the group of parameters consisting of a pressure of a wheel, a ratio of pressures of two or more wheels, a wheel contact area length of one or more wheels, an engine torque, a driving resistance and a driving torque of the motor vehicle, and generating a measured value that represents the at least one measured physical variable;
- evaluating generated measured values in order to determine the load and thereby correlating with one another measured values or load values determined therefrom that represent at least two different parameters from the group of parameters, in order to generate from the correlation a correction value and using the correction value to determine an actual load value representing the load of the motor vehicle.
A system for determining a load of a motor vehicle, the system comprising:
- at least one sensor device disposed as a wheel-side sensor device and/or as a vehicle-side sensor device and configured to detect at least one physical measured variable that is dependent on the load of the motor vehicle from two or more classes of physical parameters of the vehicle, and configured to generate a measured value that represents the detected physical measured variable;
- an evaluation device disposed to receive measured values and configured to evaluate the generated measured value in order to determine the load by correlating with one another the measured values of one or more of said sensor devices or by correlating with one another the load values determined from the measured values of the two or more classes of physical parameters in order to produce a correction value from the correlation, and using the correction value to determine a load value representing the load of the motor vehicle.
A motor vehicle, comprising:
- a plurality of wheels;
- an arrangement for receiving and holding a load;
- at least one sensor device disposed as a wheel-side sensor device and/or as a vehicle-side sensor device and configured to detect at least one physical measured variable that is dependent on the load of the motor vehicle from two or more classes of physical parameters of the vehicle, and configured to generate a measured value that represents the detected physical measured variable;
- an evaluation device disposed to receive measured values and configured to evaluate the generated measured value in order to determine the load by correlating with one another the measured values of one or more of said sensor devices or by correlating with one another the load values determined from the measured values of the two or more classes of physical parameters in order to produce a correction value from the correlation, and using the correction value to determine a load value representing the load of the motor vehicle.
