Classification: CPC B  G | IPC B  G

Claim 11:
12. A load detection and classification system for a vehicle comprising:
a vehicle weight sensor, wherein the vehicle weight sensor is at least one of: an air pressure sensor in a suspension system, a tire pressure sensing system, and a cargo weight sensor;
a plurality of vehicle sensors, including: a cargo compartment door latch sensor, a passenger door latch sensor, a key switch, a rear seat position sensor, and a plurality of seat weight sensors;
a Human Machine Interface (HMI);
a controller in electrical communication with the vehicle weight sensor, the plurality of vehicle sensors, and the HMI, wherein the controller is configured to:
determine a system enablement state of the load detection and classification system, wherein the system enablement state includes a system enabled state and a system disabled state;
monitor a vehicle weight using the vehicle weight sensor in response to determining that the system enablement state is the system enabled state;
determine a weight change of the vehicle based on the monitored vehicle weight;
compare the weight change to a first weight change threshold;
categorize the weight change as an occupant weight change or a cargo weight change using the plurality of seat weight sensors in response to determining that the weight change is greater than the first weight change threshold;
optimize a route to a destination based at least in part on the weight change in response to categorizing the weight change as a cargo weight change; and
display the optimized route to the destination using the HMI.
