Method and system for controlling alternator voltage during a remote engine start event
First Claim
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.

Abstract
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.

12. A system for controlling alternator voltage during a remote engine start event, the system comprising:
-
a receiver configured to receive a remote engine start command; a brake switch for detecting whether a brake pedal is pressed; a windshield wiper switch operatively connected with at least one windshield wiper; and at least one control unit in communication with an engine, an alternator operatively connected with the engine, a vehicle battery electrically connected with the alternator, the receiver, the brake switch, the windshield wiper switch and the vehicle battery, wherein the at least one control unit is configured to operate the alternator in a first voltage mode where the alternator is operating at a first voltage V1 to charge the vehicle battery, wherein the at least one control unit is configured to detect a brake pedal has been pressed with the brake switch; and wherein the at least one control unit is configured to operate 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 a signal from the brake switch indicating that the brake pedal is pressed. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
