Automobile Anti-Lock Brake Testing System
2024-10-08
Project Introduction
The braking system is crucial for driving safety, which is why brake components undergo extremely rigorous testing to ensure reliable performance in all conditions. Using advanced brake detection devices and precision measurement and sensing technologies, brake test platforms can evaluate brake systems for various vehicle types. The testing methods employ torque sensors and servo motors, while both analog and digital data acquisition cards are integrated with MIC-770 fanless embedded systems. The MIC-770 system seamlessly links real-time data with standard data, utilizing a PC-based structure for data acquisition, signal processing, industrial control, automation, database management, and computer monitoring techniques.
System Requirements
- The high-performance, ruggedized industrial computer equipped with the latest 12th Gen Intel® Core™ CPU (formerly named: Alder lake) must withstand 8 hours of continuous operation without stopping in order to perform brake fatigue tests.
- Compact and modular design of industrial computer system with 2 PCIe slots, supporting multiple PCIe expansion cards.
- System hardware stability is essential because the brake safety system must satisfy strict national standards.
- Multiple parameter batch sets for use under multiple conditions.
Project Implementation
- MIC-770 V3: Compact Fanless System with 12th Gen Intel® Core™ CPU Socket (LGA 1151)
- MIC-75M20: 2-slot expansion i-Module with 1 PCIe x16, 1 PCIe x4
- PCIE-1884: 32-bit, 4-ch Encoder/Counter with Preload Position Compare FIFO PCIE Card
- PCIE-1812: 250 kS/s, 16-bit, 8-ch, Simultaneous Sampling, Multifunction PCIE Card
System Description
This testing system is based on the high-performance fanless modular IPC MIC-770 V3 with a MIC-75M20 2-slot expansion i-Module, providing flexible embedded system to examine the brake capacity efficiency by measuring the brake pedal’s stepping stroke and the corresponding brake force. The 250 KS/s simultaneously high-speed sampling and the 16-bit ultra-high resolution can enable the PCIE-1812 to accurately capture the brake resistance of the tires at same time, while the PCIE-1884 encoder card can synchronously record the stepping stroke of the brake pedal. In conjunction, they plot an intensity diagram that illustrates the amount of force applied to the tire for each unit of stepping stroke applied to the brake pedal, and thereby analyze braking system actuation efficiency.
