When no more wheel revolutions occur, the value mg_u32Rpm would stay as it is. To prevent from this behaviour, this function should be called at regular intervals. It will compare the given timestamp with the last timestamp in mg_u32TickTime. If the difference between both values exeeds SPEED_TIMEOUT, the value for mg_u32Rpm will be reset to 0.
