Automotive Seat Control System

Customer Case Studies
Create an outstanding electric seat for use on buses, trains and industrial vehicles that is superior in quality, performance, safety and comfort than any of the competition within the same market arena.


Objective

The seat had to have the ability to move 15 different parts independently. It also had to allow an unlimited number of users to recall their seat preferred memory position at the touch of a button.

It was imperative that the user interface was state of the art and integratable with buses/trains or similar vehicles.


Approach

Our client approached DC to design and develop the electronics / software control systems and graphical user interface for their complex multi- motor electric seat.

DC quickly developed functional requirements specifications and architecture. This enabled the system to operate on a standard automotive CAN bus interface and allowed for seats to be networked together for easy integration into the vehicleís communication systems.

A full graphic user interface was created to provide a simple and innovative means of accessing the seats functions.

Working along side some of the industryís best seat designers, DC was able to seamlessly integrate itís technologies into the seat design.

Schematics of the electronics were developed alongside a multilayer PCB which were all designed in industry standard CAD software.

Within the design process considerations were made for manufacture and testing. Embedded firmware for an ARM Core processor was developed to provide all of the seat control functions, limit detection and CAN bus commu- nications.


Result

DC delivered operational electronics, firmware and wiring harnesses that could be integrated into the mechanical seat design.

DC also incorporated remote touch screen user interfaces, CAN bus communications and the ability to control 15 seat motors actions from a single miniature interface.


Benefit

Revolutionary low cost, high reliability CAN bus based vehicle seat control system.
