Abstract
A vehicle remote keyless entry system for an electrically actuatable vehicle lock includes a fob comprising a transmitter that is actuatable to transmit an RKE message. A vehicle-based receiver receives the RKE message. A vehicle-based controller operatively connected to the vehicle-based receiver is configured to supply electrical power from a vehicle battery to the vehicle lock to unlock the vehicle lock in response to receiving the RKE message from the vehicle-based receiver. An energy storage device, separate from the vehicle battery, supplies electrical power to actuate the vehicle lock to unlock the vehicle lock when predetermined conditions are met.

A vehicle remote keyless entry system for an electrically actuatable vehicle lock, comprising:
- a fob comprising a transmitter that is actuatable to transmit an RKE message;
- a vehicle-based receiver for receiving the RKE message;
- a vehicle-based controller operatively connected to the vehicle-based receiver, the vehicle-based controller being configured to supply electrical power from a vehicle battery to the vehicle lock to unlock the vehicle lock in response to receiving the RKE message from the vehicle-based receiver;
- and
- an energy storage device separate from the vehicle battery, the energy storage device comprising an ESD controller and a power supply, wherein the ESD controller is configured to communicate with a vehicle safety system controller to receive indication that a vehicle crash has occurred, and wherein the ESD controller is configured to control the power supply to provide electrical power to actuate the vehicle lock to automatically unlock the vehicle lock in response to receiving the indication that a vehicle crash has occurred and without receiving an RKE message.
