Interpretive meta-instructions are used, at a connected vehicle access system (CVAS) device, to implement various RKE protocols by: receiving an RKE-protocol-specific meta-instruction that has been generated by a back-end server; generating an RKE telegram based on the RKE-protocol-specific meta-instruction; and transmitting the RKE telegram to a vehicle. The meta-instruction may include: a device configuration that specifies a set of RF parameters of a CVAS-device transceiver; a template telegram that contains a first set of data fields with data values from the back-end server and that contains a second set of data fields for which data values will be generated and inserted at the CVAS device; and localization-processing commands containing instructions for modifying the second set of data fields of the template telegram.

Use of interpretive meta-instructions to implement various RKE protocols

A Bluetooth enabled Smartphone may be used for both access control and start authorization in a secure and safe way, and embodiments are backward-compatible with conventional vehicle access and start systems. A smart phone acts as an intermediary authorization device to a code generator which effectively resembles a car key that is installed in a vehicle. A Bluetooth transceiver and the code generator&#x2014;and, optionally, for the retrofit solution, an RF/LF transceiver&#x2014;are added to the vehicle. The Bluetooth transceiver communicates with the smart phone. The code generator communicates with electronic control units in the vehicle that control access, immobilization, and engine start. The communication may happen via a wired connection or, in the case of the retrofit solution, via an RF/LF transceiver that mimics an additional car key programmed to the vehicle.

Secure smartphone based access and start authorization system for vehicles

A method to learn and then pair with a pre-installed access control system of a vehicle is discussed. Communication is exchanged between the access control system and a backend cloud-based system. Required data of the access control system including its particular authentication code is extracted by a learning device. A vehicle matching data is sent to the backend cloud-based system and the vehicle is registered with the backend cloud-based system. The learning device is registered to the access control system in accordance with learning procedures implemented in the vehicle as remote entry key. The learning device is coupled to a Radio Frequency signal transmitter that has Application-Specific Integrated Circuits to generate stable RF signals at multiple frequency wavelengths. Registration of learning device includes, receiving a first access control telegram message, transmitting the first access control telegram message to the access control system, pairing the learning device with the access control system.

Method and system for remote access control

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.
