With the development of intelligent driving systems, coupled with the growing complexity and criticality of traffic conditions, the verification processes for these functions have become correspondingly more sophisticated, stringent and costly. Real-world testing is particularly constrained, as an increasing number of relevant traffic scenarios can only be evaluated within limited scopes.
Restrictions are especially pronounced for testing of hazardous operating conditions.
The resulting ViL solution is particularly well suited for the evaluation of automated driving functions. Optionally in combination with AD / ADAS hard- and software.
The advanced vehicle-in-the-loop (VIL) testing methodology has been fully developed to facilitate safe, repeatable and efficient vehicle function testing.
The application of advanced VIL in the field of intelligent driving enables functional and integration tests to be completed early in the development cycle. Since the vehicle is physically secured to the dynamometer, the system significantly enhances testing safety.
Additionally, as testing is conducted indoors, all environmental parameters (humidity, ambient light, temperature, etc.) can be precisely controlled, thereby ensuring test repeatability.

Q1: What products can Anhui Jingke vehicle powertrain test system test, and what test conditions and standards does it adapt to?
A1: This system can fully test the complete powertrain of new energy pure electric, hybrid vehicles and construction machinery vehicles, including core components such as drive motors, reducers, gearboxes, and three-electric integrated power systems. It supports full-dimensional tests including dynamic performance, transmission efficiency, durability reliability, NVH vibration and noise, high and low temperature environment coupling, and brake feedback. It adapts to national standard working conditions such as WLTC and NEDC as well as custom extreme working condition simulation. Strictly complying with GB/T, IEC, SAE, CISPR25 and other industry standards, it meets the full-process requirements for R&D, testing and certification of complete vehicles and parts.
Q2: What are the core differences and advantages between a wheel hub dynamometer and a traditional roller chassis dynamometer?
A1: Traditional roller dynamometers simulate road conditions through roller-tire contact, which easily causes slipping, tire deformation errors and poor fitting, resulting in limited test accuracy. Our wheel hub dynamometer applies direct loading at the wheel end without roller media, eliminating slipping errors fundamentally. It accurately restores road resistance, inertia and slope conditions with higher test accuracy and better repeatability. It requires no vehicle disassembly or structural modification and maintains the original vehicle state, making it more suitable for high-precision vehicle energy consumption, dynamic performance and durability calibration tests.
Q3: What vehicle types and test conditions does this wheel hub dynamometer system support? Can it be used for ADAS function verification?
A2: This system is fully compatible with fuel vehicles, pure electric vehicles and hybrid vehicles, covering passenger cars, commercial vehicles and special engineering vehicles with 2WD, 4WD and time-sharing 4WD. It supports full-condition tests including vehicle dynamic performance, fuel/electric economy, cruising range, climbing performance, high/low temperature durability and brake energy feedback. It is adaptable to standard driving cycles such as CLTC, WLTC and NEDC as well as custom dynamic conditions. With accurate real-time road load simulation, the system fully meets dynamic scenario testing and performance verification requirements for AD and ADAS functions.
Q4: Is the equipment complicated to install? Is the test energy consumption high? Does it support long-term durability tests?
A3: Adopting a modular quick-assembly design, the equipment is easy and fast to install. No vehicle or laboratory structural modification is required, and the original vehicle state is completely retained with no test damage. Equipped with four-quadrant energy-saving operation technology, the system recycles regenerative power internally and feeds surplus power back to the grid, greatly reducing long-term energy consumption costs. It supports 24-hour unattended automatic durability tests and batch cyclic tests with high stability and low failure rate, fully meeting industrialized, large-batch and long-cycle vehicle R&D and testing demands.
