  • Patent number: 9762559
    Abstract: A system and method for securely providing a mobile device with a cryptographic key in a vehicle. The method includes generating a cryptographic key pair that includes a first and second cryptographic keys. One of the keys is used to create a scannable image which is then incorporated into a label that is displayed in the vehicle, either as a physical label mounted in the vehicle or via a display screen within the vehicle. The label containing the scannable image can then be read by a mobile device at the vehicle, thereby providing the one key to the mobile device for use in sending communications to the vehicle.

  • Patent number: 9696169
    Abstract: The described principles provide a method and system for identifying a potentially closed road based on reroute requests, and of accommodating the potential road closure while continuing to test the road status periodically via routing decisions and rerouting requests. While the optimal route assumes that the potentially closed road is open, a replacement route is defined assuming that the potentially closed road is closed. A fraction of users are sent along the optimal route, and if a reroute request is received, the potentially closed road is assumed to be closed still. The affected user is rerouted to a recovery route that matches the optimal route up to the potentially closed road, and then differs from the optimal route thereafter to avoid the potentially closed road.

  • Patent number: 9645247
    Abstract: A method is described for estimating the coordinated universal time (UTC). The method involves receiving, by a satellite navigation receiver, signals broadcast by a global navigation satellite service (GNSS) satellite. The signals encode a first time of week (TOW) value. The method also involves estimating a first week number (WN) value and a first relationship between the UCT and a reference time of an onboard clock of the GNSS satellite (OFFSET) from time parameter values stored at a local memory. The method determines a first estimate of the UTC from the first TOW value, the first WN value, and the first OFFSET.

  • Patent number: 9645971
    Abstract: A system and method for providing diagnostic assistance to a driver of a vehicle when calling a call center following a diagnostic warning being displayed on the vehicle instrument panel. Upon establishing the call, indicator data representative of the warning is automatically sent to the call center where it is used to select one or more diagnostic tests targeted to particular vehicle systems associated with the warning. The test is carried out at the vehicle and the resulting diagnostic data sent back to the call center. The call is then switched to an advisor at the call center and the received diagnostic data is used to aid the advisor in providing the diagnostic assistance to the driver.
