Abstract: A method and system of over the air (OTA) reprogramming of a systems of a vehicle performed by an OTA reprogramming device are provided. For example, the method includes determining whether a vehicle ignition is on or off. When the vehicle ignition is on, the method includes sending a classic controller area network (CAN) message comprising information to operate a transmission control unit (TCU), and using the classic CAN message to operate the TCU. When the vehicle ignition is off, the method includes sending a CAN flexible-data (FD) message comprising information to reprogram the TCU, and using the CAN FD message to reprogram the TCU. The method waits until an ignition of the vehicle is off to reprogram the TCU to avoid incompatibilities with a CAN FD message.

Abstract: A method and system for vehicle control including detecting a change in a position of a transmission input interface to a neutral position indicating a transmission mode of the vehicle is shifted into a neutral gear. Responsive to receiving an input sequence at the transmission input interface, changing a neutral hold mode of the vehicle to active. The input sequence at the transmission input interface includes changing the position of the transmission input interface to a park position, holding the position of the transmission input interface at the park position for a predetermined length of time, and changing the position of the transmission input interface to the neutral position. Further, controlling the vehicle to maintain the neutral gear responsive to a change in a vehicle occupancy state while the neutral hold mode is active.
