In collaboration with Bentley Motors Ltd, we helped to develop the functionality and specification which would offer the best customer interface. Many features are not immediately obvious, for example the user’s preference of screen up or down is dependent on the table position when it was closed.
There were some technical challenges with this development, including the requirement to protect against the possibility of a hand being trapped by the mechanism, since the table contains automatic motorised movements. Through rigorous testing, with temperature profiles and force measurements, we have arrived at a solution which exerts lower forces on a hand or finger than the requirement for powered windows. The custom ‘anti-trap’ algorithms utilising speed and current measurements to achieve this level of control were developed by our engineering team.
The end product is a stylish and practical, electrically powered table and screen, fitted to the rear of the front seats. Each is individually controlled by a May & Scofield ECU that meets automotive standards and all VW80000 specifications. The table is deployed and stowed through a motorised mechanism, which is operated by a button located on the back of its corresponding front seat. The table top opens, via a second powered mechanism, to reveal a removable iPad tablet, a Bluetooth keyboard and is activated via a button on the side of the table. A torsion hinge allows manual fine-tuning of the screen position. The screen can be power closed to cover the keyboard, allowing the protected back of the casing to be used as a table. When the vehicle ignition is on, the iPad can be charged at the fast charge rate dictated by Apple’s specifications, via the power connector integrated into the iPad pouch.
This is an example of how May & Scofield's capabilities to design and manufacture complex, electrically powered mechanical systems, could be utilized by other customers in a different application or industry.
