Sensor array system for determining axle spacing

摘要

In a system for determining the spacing between axles on a vehicle, problems associated with the determination in a stop-and-go situation are overcome with a sensor array system wherein a first sensor is spaced from an array of sensors by a predetermined distance. The total length of the span of all the sensors must be greater than largest axle spacing on the vehicle to be measured. When two axles simultaneously trigger sensors, those triggered sensors' positions are sent to a computer and the axles spacing is computed and recorded. The system operates independently of the speed of the vehicle.
