Patent number: 6411874Abstract: A central control system is described that affords intuitive and easy control of numerous subsystems associated with a police car or other emergency vehicle and reduces the cockpit clutter associated with present control systems. A single user interface device is associated with a central controller capable of receiving input commands and outputting device control commands to a plurality of controlled devices or subsystems. Preferably, the central controller comprises a programmable digital computer. An emergency response system is also described which rapidly coordinates and controls operation of a plurality of emergency subsystems associated with the vehicle in accordance with a predetermined scheme of operation for the devices.
