An access system for a vehicle includes a receiver and an access module. The receiver is configured to receive a signal transmitted from a portable access device to the 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; obtain or generate an expected signal; up-sample the 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; based on the cross-correlation signal, determine 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; and permit access to the vehicle based on the round trip time.

In general, aspects of this disclosure are directed towards techniques for using a computing device to perform the functionality of a vehicle key, so that the computing device may be used to automatically unlock the doors of a vehicle and/or to activate a previously-deactivated keyless ignition system. The computing device may be associated with a vehicle, including sending an identifier associated with the computing device to the vehicle via short-range communication. The computing device may also send to the vehicle, via short-range communication, at least one unlock door signal including an access code verifiable by the vehicle, and wherein receipt of the at least one unlock door signal by the vehicle enables the vehicle to unlock one or more of its doors without further user intervention.

Provided are a vehicle-mounted communication system with which a vehicle-mounted machine is able to continue receiving a wireless signal even if the signal is interrupted. When an ID signal, indicating identification information (ID) corresponding to a vehicle, and more than M (where M is a natural number) data signals, indicating control content, are caused to be included in a wireless signal by the portable machine, and the portable machine transmits the wireless signal, the portable machine adds the ID signal into the wireless signal each time M data signals have been transmitted, and continues to transmit the wireless signal. Meanwhile, each time the vehicle-mounted machine receives the ID signal included in the wireless signal, the vehicle-mounted machine verifies the identification information the received ID signal against identification information stored in a ROM, and continues to receive the wireless signal when there is a match.

A method and system for servicing keyless vehicles is provided. The keyless vehicles include security systems that permit operation of the keyless vehicles if the security system receives a unique security signal from a smartphone. The method includes receiving a service request and unique first security data information from a customer concerning a location of a first keyless vehicle that requires service. An authorized person is transported to the first keyless vehicle in a second keyless vehicle. A customer's smartphone is provided with unique second security data whereby a customer can enter and operate the second keyless vehicle utilizing the customer's smartphone. The authorized person drives the first keyless vehicle to a service facility utilizing a second smartphone that is configured to generate a security signal to permit operation of the first keyless vehicle.

A relay attack deterrence system includes a mobile platform including a plurality of mobile platform transmitter components and a mobile platform receiver component provided therein. The system further includes a fob device having a fob receiver component, a fob transmitter component, and a motion sensor component configured to produce motion information. The fob device is configured to receive, at the fob receiver component, one or more first signals from at least one of the plurality of mobile platform transmitter components and to selectably transmit, to the mobile platform receiver component, a second signal based on the motion information and position information derived from the one or more first signals.

A vehicle control device includes: a receiving section receiving, from a user, setting processing for setting a time period in which control of a vehicle by using an information processing device is suppressed; a detecting section detecting a predetermined user operation for control of the vehicle; and a control permitting section that, in a case in which the predetermined user operation is detected in a time period that is different than the time period in which control of the vehicle is suppressed, permits control of the vehicle in accordance with the information processing device vibrating or moving, and, in a case in which the predetermined user operation is detected within the time period in which control of the vehicle is suppressed, does not permit control of the vehicle regardless of whether or not the information processing device is vibrating or moving.

The invention relates to a method for automatic recognition between a mobile electronic device (SP) and a motor vehicle (Vi) equipped with an electronic communication module (120), said mobile electronic device (SP) and the electronic module (120) of the vehicle (Vi) being capable of operating according to the BLE protocol, the mobile electronic device (SP) being in a “scanning”mode and the electronic communication module (120) of the vehicle (Vi) being in an “advertising” mode characterised in that it comprises various steps consisting of:—in the electronic module (120) of the vehicle (Vi), obtaining identification data (RPAi) of the vehicle (Vi);—transmitting at least one data frame (Td) comprising the identification data (RPAi) of the vehicle (Vi), from the electronic module (120) of the vehicle (Vi) to the mobile electronic device (SP);—receiving the at least one data frame (Td) containing the identification data (RPAi) of the vehicle (Vi), in the mobile electronic device (SP) set in “scanning” mode;—checking, in the mobile electronic device (SP), that the transmitted identification data (RPAi) is valid, then transmitting a connection request (110) from the mobile electronic device (SP) to the electronic module (120) of the vehicle (Vi).

The present disclosure is directed to an automotive computer in communication with a mobile device using an authentication manager to increase and/or reduce user privileges that determine a level of vehicle control or feature access that is granted to the user. The authentication manager may increase or decrease the user privilege to standard rider status until the authentication manager has confirmed elevated status for that user via a cloud security challenge question or via a local identification method such as using the mobile device authentication features. This process may be additionally triggered based on environmental or context-based use cases, such as a high traffic condition, local cyber-attack, or transportation of sensitive goods. The system may utilize the authentication to perform out of band pairing of the mobile device and the vehicle, which may add additional security.

A vehicle control system includes a controller and a first fob, wherein the controller is configured to control a first communicator of the vehicle to transmit a deactivation signal to the first fob based on the first fob being detected in the vehicle after locking the vehicle, and the first fob that includes a second communicator communicating with the first communicator and is configured to control the second communicator to switch at least one predetermined communication function to an inactive state based on the reception of the deactivation signal.

A communication system includes: a vehicle-mounted device; and a mobile device. The vehicle-mounted device includes: a vehicle side transmission device that transmits a request signal; a vehicle side receiver that receives an operation signal, transmitted from a mobile device side operation unit of the mobile device, and a response signal; and a vehicle side reception control device that controls the vehicle side receiver to receive the operation signal as a first channel signal, and to receive the response signal as a second channel signal. The mobile device includes: the mobile device side operation unit; a mobile device side reception device; and a mobile device side transmission device that transmits the operation signal as the first channel signal, and transmits the response signal as the second channel signal.
