Abstract: An automotive vehicle includes at least one actuator configured to control vehicle steering, shifting, acceleration, or braking, at least one sensor configured to provide signals indicative of road geometry in the vicinity of the vehicle, and a controller in communication with the sensor and the actuator. The controller is configured to selectively control the actuator in an autonomous driving mode based on signals from the sensor. The controller is configured to automatically determine a first time parameter based on a distance to a merge location between a current driving lane of the vehicle and a target lane adjacent the current driving lane in response to signals from the sensor, to automatically determine a second time parameter based on a calculated merge completion time, and to automatically discontinue autonomous control of the actuator based on a difference between the first time parameter and the second time parameter.

Abstract: A vehicle wireless unit and a method of operating the same. The vehicle wireless unit and method may be used to temporarily halt a non-interrupted data flow between the vehicle wireless unit and a cellular network over a first cellular link according to a first radio access technology (RAT), which purposely causes the vehicle wireless unit to enter an idle mode and results in the first cellular link being released. Once the first cellular link is released, the vehicle wireless unit and method may search for and, if found, establish a second cellular link with the cellular network according to a higher-order radio access technology (RAT). The vehicle wireless unit and method may be particularly useful with autonomous or semi-autonomous vehicles.

Abstract: Methods and systems are disclosed for authorizing operation of an electric vehicle that is being charged at a charging station. A computer can determine whether predefined criteria relating to the electric vehicle have been satisfied, and, if so, communicates a virtual key to the electric vehicle. The virtual key allows the electric vehicle to be operated in a limited operating mode that defines constraints on operating the vehicle. The virtual key allows the electric vehicle to be operated in the limited operating mode without a physical key or fob being present at the electric vehicle. The electric vehicle includes a processor configured to receive the virtual key and to control operation of the electric vehicle according to the constraints defined by the virtual key.
