The EPB system(Electronic Parking Brake system) is gradually replacing traditional manual parking brake methods. This system not only enables the vehicle's parking function but also adds a series of automatic control features, greatly enhancing user comfort. At the same time, it has led to a new round of higher demands for testing methods and standards.

VCARSYSTEM's Solution

The EPB HIL testing solution provided by VCARSYSTEM comprehensively covers scenarios for both individual EPB controllers and integrated domain controllers. The solution uses customized caliper fixtures (with integrated pressure sensors) to detect actuator pressure, and the clamping force is fed back to the vehicle model through the board, enabling EPB braking simulation and closed-loop control. For EPB controllers with integrated tilt sensors, the system also simulates real-world road conditions and attitude changes of the motor, fully validating the EPB performance. This provides customers with a comprehensive, high-standard EPB system testing solution.

HIL SYSTEM

VCARSYSTEM offers Hardware-in-the-Loop (HIL) testing solutions that cover the entire scope of automotive electronics, including modules for new energy powertrain systems (BMS/VCU/MCU), automotive driving systems (ACC/LKA/AEB, etc.), chassis electronic control systems (EPS/ESP/SBW/EPB/EHB/EMB), traditional powertrain systems (EMS/TCU), as well as body electronics and intelligent cockpits. It provides comprehensive HIL testing services to help customers accelerate product launch timelines.

VCAR EM

VCAR EM, developed by VCARSYSTEM for HIL platforms, is an engineering configuration tool that enables comprehensive HIL project setup. The software facilitates GPIO signal configuration, bus communication configuration for CAN/CAN FD, LIN, Ethernet, board hardware configuration, simulation model import, signal mapping, real-time host multi-task allocation and management, and project compilation. It also supports multi-task distribution management and multi-device daisy-chaining configuration, meeting diverse testing scenario requirements.

VCAR EA

VCAR EA is an automated testing software independently developed by VCARSYSTEM. It provides excellent support for editing and managing test cases, executing and evaluating them, and generating test reports, through dedicated interfaces and testing tools. Additionally, in response to the evolving demands of testing, VCAR EA supports the creation of user-defined steps to meet personalized requirements, making it widely used in the automotive testing field.

FUNCTIONS

Caliper Motor Speed Testing

It makes sure the motor runs at the right speed for dependable EPB performance.

Caliper Stroke Testing

The system verifies the caliper’s full range of motion to ensure proper brake engagement.

Caliper Clamping force Testing

It checks the force applied by the caliper to ensure effective braking performance.

Clamping Current Testing

The system measures the electrical current required to engage the caliper, ensuring proper braking force application.

Motor Fault Simulation

The testing process checks for issues such as stalling, high mechanical resistance, prolonged idle running, motor open circuit, and other potential faults.
