CANWAY's pedal actuator expansion system allows complete and real brake systems to be tested and validated under realistic operating conditions. For this purpose, vehicle dynamics are simulated and the effective braking forces are applied to the braking system by a linear system. The hydraulic braking system can be installed including all associated components, from the brake pedal, brake caliper, and brake discs to all relevant control units.
All vehicle components are located in a mobile laboratory vehicle equipped with a protective cover. The mechanical structure consists of a custom-made frame that serves to hold and secure the brake system carrier. The laboratory vehicle contains a control cabinet with an auxiliary power supply, safety technology, and interfaces to both the test object and the real-time system.
The linear system is designed for the following technical requirements and can be adapted to extended requirements.
| Stroke | 180 mm |
| Force | 500 N (maximum continuous load 420 N) |
| Speed | 1000 mm/s |
| Acceleration | 10 - 15 m/s2 |
| Service life | 75 actuations/day at 100% load (ABS braking) and 1000 actuations/day at 10–20% load |
| Interface | CAN bus |
To protect the brake system under test, the system is equipped with integrated Safe Stop safety technology. Control is via a CAN interface; the corresponding description file is included in the scope of delivery.
