System and method for identifying a change in load of a commercial vehicle

A commercial vehicle, comprising:

• an electronic stability unit having at least one inertial sensor;
• a control unit for estimating a mass of the commercial vehicle and/or a load;
• and
• a system for identifying a change in the load of the commercial vehicle, including:
• a device for querying sensor data of the at least one inertial sensor;
• and
• an evaluation unit to identify the load change when the queried sensor data exceed a maximum acceleration variation range, and inform the control unit of the identified load change to allow the load change to be taken into account in the estimation of the mass;
• wherein potential mass changes are grouped into a plurality of classes, wherein a corresponding acceleration variation range is defined for each of the classes, so that a load change is detected and forwarded only when the corresponding acceleration variation range is exceeded for a corresponding one of the classes.

A method for identifying a change in load of a commercial vehicle, the commercial vehicle including an electronic stability unit having at least one inertial sensor and a control unit for estimating a mass of the commercial vehicle and/or a load, the method comprising:

• querying sensor data of the at least one inertial sensor;
• identifying the load change when the queried sensor data exceed a maximum acceleration variation range, and
• providing confirmation of the identified load change for the control unit so that it takes the load change into account when estimating the mass;
• wherein potential mass changes are grouped into a plurality of classes, wherein a corresponding acceleration variation range is defined for each of the classes, so that a load change is detected and forwarded only when the corresponding acceleration variation range is exceeded for a corresponding one of the classes.

A non-transitory computer readable medium having a computer program, which is executable by a processor or data processing unit, comprising:

• a program code arrangement having program code for identifying a change in load of a commercial vehicle, the commercial vehicle including an electronic stability unit having at least one inertial sensor and a control unit for estimating a mass of the commercial vehicle and/or a load, by performing the following:
• querying sensor data of the at least one inertial sensor;
• identifying the load change when the queried sensor data exceed a maximum acceleration variation range, and
• providing confirmation of the identified load change for the control unit so that it takes the load change into account when estimating the mass;
• wherein potential mass changes are grouped into a plurality of classes, wherein a corresponding acceleration variation range is defined for each of the classes, so that a load change is detected and forwarded only when the corresponding acceleration variation range is exceeded for a corresponding one of the classes.
