1. A vehicle control system communication method, comprising:
- receiving, at an in-vehicle unit (IVU), a command message from a hand-held unit (HHU), wherein the command message includes first to third command frames; and
sending, from the IVU, a response message to the HHU, wherein the response message includes first and second response frames,wherein the first response frame is sent in a time period between the reception of the first and second command frames and the second response frame is sent in a time period between the reception of the second and third command frames, andwherein the first to third command frames each instruct a vehicle to perform a first function, and the first response frame includes a status of the vehicle related to the first function and an identification (id) of the IVU which is validated by the HHU prior to accepting data from the second response frame, and the second response frame includes current vehicle gauge data.

Abstract
A vehicle control system communication method, including: receiving, at an in-vehicle unit (IVU), a command message from a hand-held unit (HHU), wherein the command message includes a first command frame and a second command frame; and sending, from the IVU, a response message to the HHU, wherein the response message includes a first response frame, wherein the first response frame is sent in a time period between the reception of the first command frame and the reception of the second command frame.

14. A vehicle control system, comprising:
-
a hand held unit (HHU) for transmitting a first to third command frames, wherein the first to third command frames each direct a vehicle to perform a first function; and an in-vehicle unit (IVU) for receiving the first to third command frames and sending first and second response frames to the HHU, wherein the first response frame is sent in a time period between the reception of the first and second command frames and includes a status of the vehicle related to the first function and an identification (id) of the IVU which is validated by the HHU prior to accepting data from the second response frame, and the second response frame is sent in a time period between the reception of the second and third command frames and includes current vehicle gauge data. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A method for wirelessly communicating between a remote transceiver and a vehicle control system, comprising:
-
receiving, at a vehicle control unit, a command message from a remote transceiver, wherein the command message includes first to third command frames; and sending, from the vehicle control unit, a response message to the remote transceiver, wherein the response message includes first and second response frames, wherein the first response frame is interleaved between the first and second command frames and the second response frame is interleaved between the second and third command frames, and wherein the first to third command frames each instruct a vehicle to perform a first function, and the first response frame includes a status of the vehicle related to the first function and an identification (id) of the vehicle control unit which is validated by the remote transceiver prior to accepting data from the second response frame, and the second response frame includes current vehicle gauge or diagnostic data.
