Emergency vehicle accessory
First Claim
1. A vehicle control system for use in a vehicle comprising:
- at least one functional warning unit adapted to be mounted in the vehicle, each functional warning unit having a set of auxiliary devices, connector and a remote controller configured to control a desired state of the respective auxiliary device;
a central controller configured to sense a state of the vehicle and generate a desired state of the functional warning units based at least partially on the sensed state of the vehicle or user input and encode the desired state into an encoded packet;
a functional connection between the central controller and the at least one functional warning unit and configured to transmit the encoded packet from the central controller to each of the at least one functional warning unit;
wherein the central controller is configured to parse the desired state of the respective auxiliary device in the encoded packet and set the state of the respective auxiliary device based on the parsed encoded packet, and wherein the cumulative number of at least one functional connections is greater then cumulative number of connections from the central controller to the remote controller.

Abstract
An emergency vehicle control system with functional warning units for use in an emergency vehicle provide active visual and audible alerts. The functional warning unit includes a set of alert devices, each alert device having at least one functional connection and a remote controller, connected to the set of alert devices and configured to receive an encoded message on a single data line from a central controller. The remote controller is configured to decode the encoded message to a set of desired states for each of the set of alert devices. The remote controller is configured to control the set of alert devices, by way of the at least one functional connection, according to the respective desired state of each of the set of alert devices.
