Package Exchange and Service System Using a Key Fob Simulator

摘要

A key fob simulator for sending actuation command to a vehicle is discussed. The key fob has memory buffers, processors, and a transceiver that uses wireless communications to communicate with a backend cloud-based system. A RF transmitter of the key fob can transmit RF signals to Remote Keyless Entry (RKE) module of the vehicle. A mapping module includes a map-calculating circuit to calculate map coordinates of the key fob. A security module can receive a rolling security key of the RKE module of the vehicle. The key fob includes buttons that can be pushed by a user of the key fob to generate actuation commands by the security module. Using the RF transmitter, an actuation command and the rolling security key can be sent from security module to the RKE module of the vehicle. The RKE module then executes the actuation command after validating the rolling security key.

主权项

1. A universal key fob simulator for sending actuation commands to a target vehicle, the universal key fob simulator comprising:
one or more memory buffers; one or more processors configured to either directly calculate a rolling security key code particular for the target vehicle or assist in processing actuation commands containing one or more generated rolling security key codes particular for the target vehicle; a transceiver configured to use wireless communications to communicate with a backend cloud-based system; a Radio Frequency (RF) transmitter that has one or more Application Specific Integrated Circuits to be highly configurable in generating a set of two or more stable RF signals at different frequency wavelengths in order to transmit RF signals of a command to a Remote Keyless Entry (RKE) module of the target vehicle; a mapping module having a map-calculating circuit and configured to receive map locating signals and to calculate map coordinates of a delivery vehicle associated with the universal key fob simulator, and to store the map coordinates of the delivery vehicle in the one or more memory buffers, where the mapping module is configured to send map coordinates of the delivery vehicle, via the transceiver, to servers of the backend cloud based system, where a mapping algorithm in the backend cloud-based system is configured to use the map coordinates of the delivery vehicle to monitor a geographic location of the delivery vehicle as well as understand a geographic location of the target vehicle; a security module configured to receive, via the transceiver, one or more rolling security keys of the RKE module of the target vehicle from the servers of the backend cloud based system after the delivery vehicle reaches a pre-determined distance between the geographical location of the delivery vehicle relative to the geographic location of the target vehicle; one or more physical or software buttons configured to be pushed by a user of the universal key fob simulator, where the buttons of the universal key fob simulator are configured to be activated after receiving at least one rolling security key of the RKE module of the target vehicle from the servers of the backend cloud based system; wherein in response to pushing a first button of the universal key fob simulator, the security module is also configured to generate a first actuation command for an electro mechanical operation in the target vehicle, where the security module is configured to send the first actuation command and a first rolling security key of the target vehicle to the RKE module of the target vehicle by commanding the RF transmitter to transmit at the RF frequency of the target vehicle RF signals including the first actuation command and the first rolling security key to the RKE module of the target vehicle; and wherein the RKE module of the target vehicle is then configured to execute the first actuation command to cause the electro mechanical operation in the target vehicle after validating the rolling security key.
