Vehicle loading and unloading detection

摘要

A system for determining vehicle loading and unloading comprises an acceleration detector provided on a vehicle, a location detector for detecting the location of the vehicle and a processor that receives information detected by the acceleration detector and location detector and determines whether the detected acceleration is due to vehicle loading, unloading or travel, based on the received information. A timer may be started, when vehicle loading or unloading is determined, such that the amount of time spent loading or unloading the vehicle may be obtained. Also, a condition of a traveled surface may be determined based on information received from the acceleration detector and location detector.

1. A system for detecting the start and completion of loading and unloading of a vehicle, comprising:
an acceleration detector provided on the vehicle, the acceleration detector configured to detect a vertical acceleration of the vehicle; a location detector configured to detect the vehicle's location; a processor which receives information detected by the acceleration detector and the location detector and determines that the vehicle is loading when acceleration information indicating that the vehicle has experienced the vertical acceleration is received after location information indicating that the vehicle is approaching a loading site is received from the location detector; and a timer, wherein:
the processor is configured to start the timer when the loading is determined to start in response to the processor receiving all of: acceleration information indicating that the vehicle has experienced the vertical acceleration and the location information indicating that the vehicle is approaching a loading site is received from the location detector;the processor is configured to stop the timer when the loading has completed; andthe processor is configured to record the time taken to load the vehicle from the start to the completion measured by the timer.
