Abstract
An engine controller, system and method for collecting vehicle data. Drive torque data is determined using the engine controller in the vehicle and is stored in a memory in the vehicle. The drive torque data is stored in a non-time domain format, and may include a histogram of numbers of revolutions at predetermined intervals of drive torque values and/or a matrix of rainflow cycle counts. The drive torque data is temporarily stored in a buffer prior to being stored in the matrix of rainflow cycle counts using back-checking and binning. The drive torque data is downloaded from the vehicle and transmitted to a central data collection center.
