Here is a typical installation in a lowered floor minivan for a wheelchair driver. The chassis is mounted up front in the vehicle next to the passenger seat; it does not inhibit wheelchair movement into the driver’s area. The servomotors are located under the driver’s dash area and connect mechanically to the steering column and the gas/brake pedals. These servomotors can be disengaged to allow operation of the vehicle utilizing the factory controls in less than 10-seconds, and do not interfere with the driver. The specially designed mounting system is required for all AEVIT® input devices and VGA displays. They feature shock ball mounting with articulating arms that allow all controls to be positioned perfectly for each driver. They are available in door and floor mounting designs.
AEVIT® 2.0 input devices feature dust, moisture, and impact resistant housings to protect against the rigors of typical vehicle operation. They also feature extremely robust internal mechanics developed by EMC for this market over 15-years ago, have survived the test of time. Sealed ball bearings, and precision machined parts are all factors leading to many years of trouble free service. Each input device contains three-redundant feedback encoders for AEVIT 2.0 computers to track their exact position in relation to your inputs. *Each Input Device contains three-redundant feedback encoders for AEVIT 2.0 computers to track their exact position in relation to your inputs. *The “L-Series” input device for gas/brake control, features internal adjustable dampeners to allow for independent adjustment of mechanical “forced-feedback” to the driver. *The “W-Series” input device for steering control, features a friction collar for ultra-smooth inputs, and an internal clutch to provide protection for the electronics inside.
Starting with a nearly indestructible roto-molded cover, the chassis measures only 12″L x 7″W x 12″H, saving valuable floor space in the vehicle. The main purpose of the chassis is not only to house the primary control modules, but also allow for quick removal of any module for service. The chassis also serves as the connection point for the evaluation controls, and contains a built-in flash drive for easy software updates and stored telemetry data.
The AEVIT® 2.0 servomotors have proven their ultra-reliable robust design through millions of hours of operation over the past 20-years. The secret to this unprecedented reliability is the “dual wound” redundancy that is exclusive to the AEVIT® servomotors; two motors are contained in each housing, eliminating the need for separate backup motors. The AEVIT® servomotors are always communicating; the system checks both windings constantly, informing the user of any errors.
