1. A method for regulating the output voltage setpoint (VCONTROL,ADAPT) of an alternator, comprising the steps of:
establishing a first voltage setpoint of the alternator corresponding to a first alternator load level (VSet0) and an initial value (V100,INIT) for a second voltage setpoint of the alternator corresponding to a second alternator load level (V100) greater than the first load level; serially communicating information identifying the voltage level of a battery (VBAT,ADAPT) charged by the alternator through a battery cable continually to a controller; using the controller to incrementally increase the second voltage setpoint (V100) from its initial value (V100,INIT) until a desired relationship is reached between the battery voltage (VBAT,ADAPT) and the first voltage setpoint (VSet0), and to then define an end value (V100,END) for the second voltage setpoint (V100); using the controller to determine an adaptive variable (RADAPT) based on the first voltage setpoint (VSet0) and the defined end value (V100,END) for the second voltage setpoint (V100), and to determine, utilizing the adaptive variable (RADAPT), offsetting levels of the alternator output voltage setpoint (VCONTROL,ADAPT) that compensate for battery cable voltage losses estimated to occur over a range of alternator load levels between the first and second alternator load levels; and continually regulating the alternator output voltage setpoint (VCONTROL,ADAPT) to an offsetting level that compensates for the respective battery cable voltage drop between the alternator and the battery and maintain the battery voltage (VBAT,ADAPT) at a substantially constant level. |
