METHOD AND SYSTEM FOR CONTROLLING ALTERNATOR VOLTAGE DURING A REMOTE ENGINE START EVENT

摘要

A method and system for controlling alternator voltage during a remote engine start (“RES”) event is provided. The method includes receiving an RES command into at least one control unit of the system. The method further includes starting an engine in response to receiving the RES command and operating an alternator in a first voltage mode where the alternator is operating at a first voltage V1 to charge a vehicle battery. The method further includes detecting a brake pedal has been pressed with a brake switch. The method further includes operating the alternator in a second voltage mode where the alternator is operating at a second voltage V2, which is less than the first voltage V1, to charge the vehicle battery based on detecting the brake pedal has been pressed.

1. A method for controlling alternator voltage during a remote engine start event, the method comprising:
receiving a remote engine start command into at least one control unit of a vehicle control system; starting an engine in response to receiving the remote engine start command; operating an alternator operatively connected with the engine in a first voltage mode where the alternator is operating at a first voltage V1 to charge a vehicle battery; detecting a brake pedal has been pressed with a brake switch in communication with the at least one control unit of the vehicle control system; and operating the alternator in a second voltage mode where the alternator is operating at a second voltage V2, which is less than the first voltage V1, to charge the vehicle battery based on detecting the brake pedal has been pressed.
