Vehicle Dynamics Control proline (ABS, EDS, ASR, ESP)

Vehicle Dynamics Control proline (ABS, EDS, ASR, ESP)

With this teaching and training rig all functions and processes, errors and measuring values can be demonstrated and examined as they are in the original brake system with vehicle dynamics control. The fully functional brake system brakes the individual wheels depending on operating and control conditions. Regular braking, ABS, ASR, EDS, ESP or individual wheels. All original parts and required components are clearly arranged in the IPO-principle on the color printed front panel. The required power supply, wiring and component configuration are already integrated into the system and preset, ready for operation. This means the system can be put into operation immediately upon setup.

Engineering

The four wheels are driven via adjustable friction rollers which are powered by an electric motor with freely adjustable speed. The fully functional brake system brakes the individual wheels according to the operation and control situation. Normal braking, ABS, ASR, EDS, ESP, or decrease in braking pressure for ABS on the individual wheels. Wheel rotating speed and brake pressure of the individual wheels, system pressure, pedal force and vehicle speed are read from digital display devices. Control of the individual valves and the hydraulic pumps are displayed on LED's.

For simulation of the ESP functions the drivers requirements are transferred to the vehicle dynamics control device via the steering wheel and steering angle sensors by the CAN-BUS. In addition, depending on the driving speed and wheel angle, the various driving and control conditions such as insufficient turning, excessive turning, contra skidding with or without braking are produced.
