Increasing demands for further functionality in the car, both by statutory requirement and customers, have led to an increased complexity in the car.
Advantages of a network
Easier to add further functions and install accessories
Because the control modules in the network are already connected to each other and are easy to add more information to, all that is required is:
to connect the sensors to the nearest control module
to connect the controlled component to the nearest control module
to download software to alter the configuration and programming of the network.
The length of the wiring and the number of components which are introduced with the car are less than previously.
