Abstract
Method and apparatus are disclosed for pre-fluxing motors of vehicle door e-latches. An example vehicle includes a door including a handle that includes a switch. The handle also includes an e-latch that includes a latch and a motor for the latch. Responsive to detecting grasping of the handle via the switch, the e-latch is to pre-flux the motor and transmit an authentication request. The example vehicle also includes a body control module to cause the motor to unlock the door via the latch responsive to authenticating a fob upon receiving the authentication request.
