| Quick Installation |
With universal attachement less than 10 minutes |
| Single Operator Control |
Component weight about 16kg. Handy terminal user guidance and text in clear |
| Universal Actuator Unit |
Installation on driver seat. No modifications to the vehicle. The actuator unit is temperature proof from -40°C up to +80°C and designed for endurance tests. Minimum self warm up. Aerodunamically neutral design for climatic measurements. |
| Mobile Units |
AUTOPILOT systems are assignable to several test stands. Different actuator units can be operated on one test cell. |
| Praxis Oriented Software |
Teach-in of the gear positions with commands in dialog (check list). Comfortable user interface with simple operation. Drive cycles can be defined without programming experience. |
| Learn Cycle |
Once per vehicle type an self learn cycle has to be performed. This cycle is independent to the drive cycle to run. During this automated learn cycle the AUTOPILOT learns all relevant parameters that are required to drive the vehicle and any drive cycle. |
| Continual Learning od Clutch Behavior |
Correct start point over the whole test period. Compensation of wear & tear during the complete ensurance test. Automatic adaptation to the true bite point of the clutch. |
| Constant Control Algorithm During Test Drive |
Ideal driver for correlation, research, development, and quality control. |
| Highest level of safety |
Safe non-energized basic positions. The clutch pedal is disengaged and the accelerator pedal is released. Emergency-off button on actuator unit. 24V technique on actuator unit. Skid monitoring on the wheels (Wheel drum slip monitoring and compensation). Gear shifts forces may be programmed. Safety tolerance band monitoring (speed errors). Permissible repetitions of a shift process may be preset. Speed and engine speed monitoring |
| Data Managers |
Local data managers for vehicle data, drive sycles, shift tables. Networking capable. |
| Support of various transmission types |
Automatic trasmission:
- Standard
- Triptronic®
- column shifter (optional)
Manual trasmissions:
- Standard, sequential, each with/without clutch
- SeleSpeed®
- Smart®
|
| Integration |
Digital interface to emission benches with digital outputs and inoputs. Optionally different interfaces for host computer communication: AK+SCPI (serial or TCP/IP) Bit parallel + analog |
| Drive Cycles |
Directly accessible standard drive cycles. Drive cycle files can also be created as ASCII files in different file formats. Instructions from host computer systems can be executed in different operational modes. Drive cycles can contain additional data as road gradient commands, sub cycles, control commands, etc. |
| Human driving style |
Speed control algorithm with human driving style. Choice if different human driver models for emission tests. Highly accurate and repeatable control. |
| Automated modes |
Closed loop control modes for:
- Vehicle speed
- Engine speed
- Throttle traces
- Clutch traces
- External unit as intake manifold pressure, force/torque, etc.
- Reproduction of recorded tracks with max. 10Hz
|
| Manual Modes |
Different manual operation modes to drive and operate the vehicles via keyboard or handy terminal |
