A vehicle communication device includes a first antenna, a second antenna, and an isolation circuit. The first antenna is configured to emit and detect a first signal and the second antenna is configured to emit and detect a second signal. The isolation circuit is configured to isolate the first signal and the second signal from each other. The isolation circuit includes at least one resonator arranged between the first antenna and the second antenna. The first antenna and the resonator are separated by a first distance along a first axis, and the second antenna and the resonator are separated by a second distance along the first axis, where the first distance is shorter than the second distance.

A computer-implemented method includes predicting, via a predictive analytical model, a time interval associated with a future key-on event for a vehicle. The predictive analytical model is based at least in part on key-on event data. The method includes generating, based at least in part on the predicted time interval, a power mode instruction configured to cause a vehicle Telematics Control Unit (TCU) or Phone as a Key (PaaK) system to change a TCU state from a low energy state to a higher energy state, and transmitting, based on the predicted time interval, the power mode instruction to the vehicle TCU.

Method and apparatus are disclosed for dead zone mitigation for a passive entry system of a vehicle. An example vehicle includes antenna modules to measure signal strengths of broadcasts from a mobile device. The example vehicle also includes a wireless module to, when the mobile device is in a dead zone, generate first and second predictors and enable passive entry when the first and second predictors match and indicate that the mobile device is in a passive entry zone, and a sensor detects a user. The example vehicle also includes a body control module to unlock a door when passive entry is enabled.

A backup power system in a vehicle that provides temporary power to one or more electronic control units (ECUs) upon failure of a main power supply. The backup power system includes an energy reservoir that stores electric charge. A charging circuit is electrically connected to the energy reservoir to generate charge for the energy reservoir during normal operation of the vehicle. A discharging circuit for supplying backup power is electrically connected between the energy reservoir and the ECUs. A diagnostic circuit is electrically connected to the energy reservoir and a microcontroller. The microcontroller is configured to monitor a slew rate of the energy reservoir as an amount of stored electric charge in the energy reservoir changes, determine if the slew rate is within a predetermined range, and when the slew rate is not within the predetermined range, generate a first error signal.
