The suspension system of the chassis is not only a critical component of the vehicle but also directly affects the driving experience, handling performance, and ride comfort. As the automotive industry moves towards electrification and intelligence, semi-active and active suspension technologies are rapidly developing and being widely adopted. However, to successfully apply semi-active and active suspension technologies in actual vehicle production, rigorous testing and validation are essential.

VCARSYSTEM's Solution

Leveraging years of experience in HIL simulation,VCARSYSTEM has developed a testing solution for semi-active and active suspension systems. This solution supports various types of active suspensions, including air suspension, CDC dampers, electromagnetic dampers, hydraulic suspension, and linear motor suspension. It also covers multiple testing modes, such as pure HIL mode and system integration mode (full vehicle four-post test bench, suspension four-post setup). This comprehensive and efficient solution enables the thorough validation of suspension system performance under complex conditions, providing strong technical support for the development, verification, and optimization of suspension systems.

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

Functional Verification

Comprehensive verification of the suspension system functions, covering braking, acceleration pitching, height adjustment, automatic leveling, vertical body control, and coordination with lateral and longitudinal control, such as shortening braking distance.

Fault Injection Testing

Injecting fault scenarios such as bus faults and electrical faults into the suspension testing system to verify the safety performance of the active/semi-active suspension system under failure conditions.
