Technical Advantages
● Micro-high-precision real-time simulation capability
- Accurately reproduce the dynamic response characteristics of the braking system under extreme conditions such as low-adhesion roads and emergency braking
- Ensure ultra-real-time data interaction between ECU and virtual environment, with simulation accuracy of microseconds
● Customized component-level model support
- Supports import of multiple formats such as FMU and C code, and is compatible with mainstream development environments
- Customizable models of key components such as brakes, calipers, hydraulic valves, etc., to achieve full-scale adaptation from mechanical structure to control logic
- Provides verification solutions for new generation braking systems such as EMB wire control brakes and EHB electronic hydraulic brakes
● Full-process closed-loop testing
- One-stop solution from simulation scene construction, test automation, data collection to result analysis (data post-processing module)
- Improved automated testing efficiency
● Multi-intelligent fault diagnosis
- Built-in fault simulation library (such as sensor signal drift, CAN communication interruption, actuator jamming), which can dynamically trigger typical faults of the braking system, and verify the compliance of ECU fault code generation, redundancy mechanism and failure strategy in combination with diagnostic protocols to meet functional safety requirements.
Typical Test Scenarios
Typical application of ibooster in the loop in the wet brake system solution: Ibooster uses a real hydraulic test bench. CarMaker outputs the brake pedal opening and converts it into a push rod stroke signal. The electric cylinder is position-controlled based on this signal to push the Ibooster push rod to move the corresponding displacement. The displacement sensor in the Ibooster assembly obtains the displacement information and transmits it to the controller. The controller calculates the required deceleration of the vehicle, controls the execution motor to assist, and converts it into master cylinder pressure together with the push rod force and transmits it to each wheel cylinder. The oil pressure sensor collects the wheel cylinder pressure and gives it to the vehicle model to realize braking, thus achieving closed-loop control of Ibooster.
