<p>The invention relates to a stop-start control system (SSCS) for use in vehicles that comprise a stop-start device (SSD), at least one energy storage device (ESD) to power the stop-start device (SSD), and at least one engine control unit (ECU) operating a set of parameters in at least one operating mode, wherein the stop-start control system (SSCS) comprises a stop-start control unit (SSCU) that is provided to enable or to disable an operation of the stop-start device (SSD), depending on an evaluation of a subset of parameters (12) of the set of parameters from an output signal of the engine control unit (ECU). The automatic start stop is enabled or inhibited as a function of the estimated state of charge SOC of the battery and the estimated battery temperature. The battery temperature is estimated based on engine coolant temperature, ambient temperature, engine rotational speed and vehicle speed, taking account of thermal transfer. The battery SOC is estimated based on the battey voltage, the estimated current drawn due to the starter motor and the estimated current generated due to alternator. A neural network is used for the computation. The invention allows to use less sensors, in particular there is no need to use an expensive intelligent battery sensor.</p> |
