Abstract: A method of in-vehicle tracking begins with establishing a communication link between a mobile device and a navigation system of a vehicle. The navigation system presents driving instructions leading to a destination. Each of a plurality of locations is serially passed over the communication link from the mobile device to the navigation system. Additionally, each of the plurality of locations is serially set, as it is communicated, as the destination within the navigation system. As the destination within the navigation system is updated, the driving instructions leading to that destination are updated as well.

Abstract: A vehicle includes a rail-mounted component and a restraint monitoring system. The rail-mounted component can include one or more restraints. The restraint monitoring system includes a restraint control module, an encoder-decoder module, and a rail-mounted component control module. The rail-mounted component control module can include a restraint deployment loop and a restraint diagnostic loop. The restraint deployment loop can include a deployment signal amplifier. The restraint diagnostic loop can include a diagnostic signal amplifier. In examples that include both the deployment signal amplifier and the diagnostic signal amplifier, the deployment signal amplifier and the diagnostic signal amplifier may be wired in parallel.

Abstract: This disclosure is generally directed to an RFID system that includes a hybrid RFID tag offering a functionality of a passive RFID tag and an active RFID tag. When operating as a passive RFID tag, an RF signal received from an RFID reader is harvested to produce a DC voltage for powering the hybrid RFID tag. The harvested DC voltage is coupled into a capacitor at a slow-charging rate so as to avoid a capacitor inrush current causing an abrupt power supply voltage drop. A controller chip in the hybrid RFID tag can execute some RFID functions at this time, thereby speeding up a response to the RFID reader. The capacitor is then charged at a fast-charging rate for storing a reserve charge. The hybrid RFID tag can subsequently use the reserve charge to operate as an active RFID tag without waiting for an RF signal from the RFID reader.

Abstract: A motor vehicle secondary hood latch release mechanism comprises a striker, a primary hood latch, and a secondary hood latch. A remote secondary hood latch release device actuates the secondary hood latch only after a primary hood latch switch provides a signal to the controller indicating that the primary hood latch is in the disengaged position. A hood sensor provides a signal when the hood has been lifted to the open condition. The controller actuates the secondary hood latch to the disengaged position for a prescribed period of time upon actuation of a vehicle system input device, and thereafter the controller actuates the secondary hood latch to the engaged position upon the earlier of expiration of the prescribed time or the hood sensor providing the signal to the controller that the hood has been lifted to the open condition.

Abstract: A computer in a vehicle includes a processor and a memory storing processor-executable instructions. The processor is programmed to shift a transmission of the vehicle from a gear into park upon receiving a first signal from a first active sensor beyond a signal threshold and then, within a time threshold, receiving a second signal from a second active sensor beyond the signal threshold. The signals are correlated with distances from the respective active sensor to a detected object.
