ABS/ASR Power Control System Trainer – DL DM28
The ABS/ASR Power Control System Trainer (DL DM28) by DE LORENZO is an advanced educational training system designed for the study and demonstration of automotive braking and traction control technologies. This trainer provides a realistic representation of the operating principles of the Automatic Braking System (ABS) and Anti-Slip Regulation (ASR) systems used in modern motor vehicles.
This training unit facilitates the simulation of normal vehicle operating conditions, including driving, braking, and braking scenarios where the ABS/ASR system is activated. It demonstrates system responses during extended braking delays, wheel locking conditions, and slipping situations. The trainer also represents the functioning of the anti-skidding ASR system, allowing learners to understand traction control behavior under different operating conditions.
The system is built with a microprocessor controller to simulate real vehicle electronic control functions. It enables laboratory experiments focused on measuring voltage levels, signal sequences, and system responses to dynamic input signal variations. Additionally, students can test hydraulic pressure changes in braking circuits and analyze how the ABS/ASR system regulates brake force under different conditions.
