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.
Claims19
A vehicle comprising:
- a door including:
- a handle including a switch;
- and
- an e-latch including:
- a latch;
- and
- a motor for the latch,
- wherein, responsive to detecting grasping of the handle via the switch, the e-latch is configured to pre-flux the motor and transmit an authentication request;
- and
- 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, wherein the motor is pre-fluxed while the body control module authenticates the fob.
A method comprising:
- detecting, via a switch, a handle of a door being grasped;
- responsive to detecting grasping of the handle, pre-fluxing a motor and transmitting an authentication request via an e-latch, wherein the motor is configured to drive a latch of the e-latch;
- authenticating, via a body control module, a fob upon receipt of the authentication request;
- and
- causing, responsive to authenticating the fob, the motor to unlock the door via the latch, wherein the motor is pre-fluxed while the body control module authenticates the fob.
A vehicle comprising
- a door including:
- a handle including a switch;
- and
- an e-latch including:
- a latch;
- and
- a motor for the latch,
- wherein, responsive to detecting grasping of the handle via the switch, the e-latch is to pre-flux the motor and transmit an authentication request;
- 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;
- and
- wherein, responsive to detecting that the latch is in an unlocked position when the motor is pre-fluxed, the e-latch causes the motor to return the latch to a locked position until the fob is authenticated.
