Abstract:
1. An electrical system for an automotive vehicle, comprising: an electrical generating machine having a voltage output set by a set point voltage, a battery coupled to the voltage output of the electrical generating machine and an electronic control unit (ECU) that sets the set point voltage; and the ECU selecting one of a plurality of control modes to control the electrical generating machine based on vehicle operating parameters, setting a range for the set point voltage based on the selected control mode and setting the set point voltage based on a feedback parameter for that control mode, wherein the control modes include a trickle charge mode wherein the feedback parameter is battery charge current and the ECU sets the set point voltage to maintain the battery charge current at a predetermined level and a regeneration mode wherein one of the vehicle operating parameters that the ECU bases determining whether to branch to the regeneration mode is whether a vehicle brake has been applied and the ECU determining to branch to the regeneration mode only if the vehicle brake has been applied.
