A system is provided and includes a receiver and an access module. The receiver is configured to receive a signal transmitted from a portable access device to a vehicle. The access module is configured to generate a differentiated signal based on the received signal, up-sample the differentiated signal to generate a first up-sampled signal, up-sample an expected signal to generate a second up-sampled signal, cross-correlate the first up-sampled signal and the second up-sampled signal to generate a cross-correlation signal, determine, based on the cross-correlation signal, a phase difference between the first up-sampled signal and the second up-sampled signal, determine a round trip time of the signal received by the receiver based on the phase difference, and permit access to the vehicle based on the round trip time.

In one form of the present disclosure, vehicle includes: a plurality of electronic devices; a first communication device configured to communicate with a terminal using a first communication method; a second communication device configured to communicate with the terminal using a second communication method; and a control device configured to wake up the plurality of electronic devices when the first communication device wakes up, switch the plurality of electronic devices to a sleep mode when the first communication device is switched to the sleep mode, and selectively control the wake up and the sleep modes of the second communication device based on a message received from the terminal.

An in-vehicle encryption system for use in a vehicle comprising a plurality of vehicle subsystems. The system comprises a security ECU module that communicates with a remote cryptographic module, the security ECU module comprising a processor and a per vehicle master secret (PVMS) value stored in the security ECU module. The security ECU module uses the PVMS value to authenticate with the remote cryptographic module and to establish an external encrypted communication link with the remote cryptographic module. The system further comprises a first subsystem ECU module that generates a first globally unique identifier (GUID) and a second subsystem ECU module that generates a second GUID. The security ECU module uses the first GUID value to establish a first encrypted communication link with the first subsystem ECU module.

In some implementations, a vehicle experience system may receive a service request associated with a vehicle. The vehicle experience system may qualify a driver for a vehicle experience involving the vehicle. The vehicle experience system may provide, to a user device associated with the driver, a verification code for authenticating the vehicle experience involving the driver and the vehicle. The vehicle experience system may provide, to a location management system associated with the vehicle, a notification that the vehicle is to be involved in the vehicle experience. The vehicle experience system may provide, to the location management system and based on receiving scan data being associated with the verification code, the authentication of the vehicle experience to enable a provisioning device to facilitate access to the vehicle.

Disclosed is an electronic device for performing ultra wide band (UWB) multi-ranging. The electronic device includes a communication system that performs UWB communication with multiple terminals and a processor. The multiple terminals include a smart key and at least one digital key. The smart key is a device that is ranged on a one off basis in response to a user input and the at least one digital key includes at least one device that is periodically ranged. The processor set priorities of the plurality of terminals, select one of the plurality of terminals between which pieces of ranging timing overlap based on the priorities of the plurality of terminals when the pieces of ranging timing of the plurality of terminals overlap, and perform ranging on the selected terminal through the communication system.

To utilize a shared vehicle, a user can request access to the vehicle, which results in the generation of a virtual key. The virtual key is provided to a plurality of different devices, such as a vehicle device at the vehicle, and a user device in the possession of the user. Access to the vehicle can be granted and maintained by verification of the virtual key against data from an identification device at the vehicle, or from the user device. In this way, multiple options for vehicle access are available to the user, which increases flexibility and user-friendliness.

The present systems, devices, and methods relate to managing shared vehicle access. Vehicle access can be provided to a candidate user based on whether the user is included in a list of at least one user associated with a respective virtual key. Virtual keys can be created, or lists of at least one user can be updated to include the candidate user, to in turn provide vehicle access. Virtual keys can be stored in a plurality of virtual key slots, with vehicle access being provided based on a virtual key stored in an active key slot. Status reports can be sent to a reservation management device, for updating virtual keys or lists of at least one user.

A system comprising a transponder having a user interface to receive commands from a user and to operate a virtual assistant. A micro-computer in an automobile, which is responsive to the transponder, and wherein the transponder and the micro-computer configured to have conversations. These include conversations regarding the automobile, and between a user of the transponder and the virtual assistant utilized by the transponder. The conversations are recorded and recallable at a later time, wherein the virtual assistant responds to future commands or questions from the user based on prior commands or questions from the user.
