Patent attributes
The disclosure is directed to a vehicle cargo bed capacitive sensor system programmed to determine when items in the cargo bed (e.g., the bed of a pickup truck) are being manipulated. The system may include one or more capacitive sensors disposed on one or more cargo bed walls. The system detects items exiting the cargo bed (e.g., by falling out of the cargo bed), and detects shifting cargo. The system may also detect a person reaching into the cargo bed, and can provide information such as the location where the cargo was taken or lost from the cargo bed, and live feed images of the intruding party. The system may automatically extend and contract the capacitive field to control sensor sensitivity, and adjust the sample rate of the sensor data based on characteristics of vehicle operation, such as drive mode, speed, GPS direction, and other factors.
