Abstract
A method in a first vehicle for determining a load of the first vehicle includes obtaining, from one or more sensors arranged in or at the first vehicle, an internal value of the load and an associated accuracy of the load; obtaining, from an external source, an external value and an associated accuracy of the load; and determining, based on a comparison of the respective accuracies, the load to be the internal value, the external value or a combination thereof. A method in a second vehicle for facilitating a determination of a load of a first vehicle comprises: obtaining, from one or more sensors arranged in or at the second vehicle, an internal value of the load of the first vehicle and an associated accuracy; and sharing the internal value and the associated accuracy with the first vehicle.
Claims12
A computer-implemented method in a first vehicle for determining a load of the first vehicle for use in controlling the first vehicle, the method comprising:
- obtaining, from one or more sensors arranged in or at the first vehicle, an internal value of the load and an associated accuracy of the load;
- obtaining, from an external source, an external value and an associated accuracy of the load;
- and
- determining, based on a comparison of the respective accuracies, the load to be the internal value, the external value or a combination thereof,
- wherein each accuracy includes a confidence interval, a tolerance, a measurement quality indicator provided by the sensor, or a measure for quantifying statistic dispersion;
- and
- controlling at least one of suspension settings, damping of chassis movements, braking response, cruise control, powertrain parameters, or skid avoidance of the first vehicle based on the determined load.
A first vehicle configured to determine a load of the first vehicle for use in controlling the first vehicle, comprising:
- one or more sensors providing an internal value of the load and an associated accuracy of the load;
- a communication interface towards an external source for obtaining an external value and an associated accuracy of the load;
- and
- processing circuitry configured to compare the respective accuracies and to determine, based thereon, the load to be the internal value, the external value or a combination thereof,
- wherein each accuracy includes a confidence interval, a tolerance, a measurement quality indicator provided by the sensor, or a measure for quantifying statistic dispersion, and to control at least one of suspension settings, damping of chassis movements, braking response, cruise control, powertrain parameters, or skid avoidance of the first vehicle based on the determined load.
