Remote vehicle control system utilizing multiple antennas

A remote vehicle control system, comprising:

• a base data processor and transceiver unit (base TPU) for mounting in a vehicle;
• a first substantially omni-directional antenna mounted to the vehicle and operatively coupled to the base TPU;
• a mobile device, the mobile device having a data processor and transceiver unit (mobile TPU), and a second antenna connected to the mobile TPU;
• wherein the base TPU and mobile device communicate wirelessly with one another via an IEEE 802.15.4 communication protocol;
• third and fourth antennas mounted to the vehicle that are tuned to communicate over the IEEE 802.15.4 bandwidth used for wirelessly communicating between the base TPU and the mobile device, wherein the third antenna has an operable radiation pattern extending proximate to a driver's side of the vehicle but substantially not to an opposite side thereof and the fourth antenna has an operable radiation pattern extending proximate to the opposite side of the vehicle but substantially not to the driver's side thereof;
• wherein the base TPU provides driver and passenger passive keyless entry functions by detecting the presence of the mobile device proximate to the vehicle driver side or the vehicle opposite side based on the ability of the mobile device to communicate via the third and fourth antennas or by the quality of such communication.

A remote vehicle control system, comprising:

• a battery providing motive power for the vehicle;
• a battery charging subsystem, the battery charging system monitoring the charge state of the battery whilst recharging;
• a base transceiver mounted in the vehicle and operatively connected to the battery charging subsystem;
• an electronic key fob, the key fob having a transceiver and a display operatively connected to the transceiver;
• wherein the base transceiver and the key fob communicate wirelessly with one another via an IEEE 802.15.4 communication protocol and wherein the base transceiver periodically communicates the state of the battery charge to the key fob whilst the battery is connected to an electrical power outlet for recharging.
