Method for determining the weight of at least one occupant of a vehicle
First Claim
Patent Images
1. A motor vehicle, comprising:
- a chassis;
a vehicle body constructed on the chassis and resting on the chassis;
at least one sensor for detecting a first load which acts on the chassis as a first weight value at a first time point prior to entering of at least one occupant into the motor vehicle and for detecting a second load which acts on the chassis as a second weight value at a second time point after entering of the at least one occupant into the motor vehicle, wherein the at least one sensor is constructed for detecting a dynamic load acting on the vehicle body during a drive of the motor vehicle said dynamic load defining a vibration behavior of the vehicle body; and
an analysis unit operatively connected with the at least one sensor, for determining the weight of the at least one occupant as a difference between the first and second weight values, wherein the analysis unit is configured for determining a distribution of the weight of the at least one occupant in the motor vehicle as a function of the vibration behavior of the vehicle body.

Abstract
A method for detecting a weight of at least one occupant of a motor vehicle includes the steps of detecting a first load which acts on a chassis of the motor vehicle as first weight value at a time point prior to entering of the at least one occupant into the motor vehicle, detecting a second load which acts on the chassis as second weight value at a second time point after entering of the at least one occupant into the motor vehicle; and determining the weight of the at least one occupant by forming a difference between the first and second weight values.
