Abstract
An interdependent control apparatus for an accessory mounted to a vehicle. An accessory control connector is connected to the vehicle's on board diagnostic port data bus and an accessory microcontroller is in data communication with the accessory control connector. An output device associated with and operating a component of the accessory is in data communication with the accessory microcontroller for control of an accessory parameter. Parameters of a vehicle are also controlled by the accessory microcontroller. Data from the accessory is also input to the accessory microcontroller representing a parameter of the accessory. Data is input from both the data bus and the vehicle accessory to the accessory microcontroller. Output control data from the accessory microcontroller can control a vehicle parameter and most importantly controls an accessory parameter. This is particularly useful for safety interlocks to stop the engine operation in response to a potentially hazardous event, such as a change in one or more of the vehicle input parameters.
