As active safety and intelligent driving systems continue to evolve, vehicle targets used in proving-ground testing must move beyond basic geometric representation. For modern ADAS and automated driving validation, a passenger vehicle target needs to reproduce not only the shape and sensor characteristics of a real vehicle, but also its dynamic lighting behavior and synchronized interaction with motion platforms.

PRIAUTO has upgraded its 3D Passenger Vehicle Target with a full lighting system and wireless synchronization capability, providing a more realistic and technically advanced test object for vehicle-to-vehicle ADAS testing, night-time scenario validation and complex dynamic traffic simulation.

The enhanced target supports multiple lighting functions, including daytime running lights, position lamps, brake lights, and left and right turn signals. These features allow the target to simulate more realistic vehicle behavior in scenarios such as following, braking, turning, lane changing, low-speed cut-in, rear-end risk generation and night-time traffic interaction. The target also features a wireless interface that enables synchronization with a wide range of motion platforms, supporting coordinated control between target motion and lighting status during dynamic tests.

Traditional vehicle targets often focus primarily on external geometry and basic sensor detectability. However, in real traffic, vehicle lighting signals are an essential part of scene understanding. Brake lights indicate deceleration intention, turn signals provide lane-change or turning cues, position lamps and tail lamps define vehicle contour in low-light environments, and daytime running lights improve visual recognition under mixed lighting conditions.

For camera-based perception systems, lighting signals directly affect object detection, vehicle classification, intention recognition and trajectory prediction. For multi-sensor fusion systems, lighting information can serve as a contextual cue that complements radar and LiDAR observations. For ADAS functions such as AEB, FCW, ACC and LKA, the correct interpretation of front-vehicle lighting behavior can influence risk assessment and control response.

By integrating a full lighting system into the 3D passenger vehicle target, PRIAUTO enables more complete validation of perception and decision-making algorithms under conditions closer to real-world traffic.

Night-time testing is becoming increasingly important in advanced safety assessment. Low illumination, glare, high contrast, reflective surfaces and incomplete target contours can significantly challenge vision systems and perception fusion algorithms. A vehicle target without realistic lighting behavior cannot fully represent the detection conditions encountered in real night-time traffic.

The upgraded PRIAUTO 3D Passenger Vehicle Target supports multiple illumination modes, including:

With these lighting functions, the target can support a broader range of night-time and low-visibility validation scenarios, including front-vehicle braking, turning, lane-change intention, stop-and-go traffic, rear-end collision risk, urban low-speed interaction and highway following conditions.

This capability makes the target especially valuable for OEMs, sensor suppliers, testing organizations and research institutions developing or evaluating camera-based perception, sensor fusion, automatic emergency braking and forward collision warning systems.

In dynamic ADAS testing, timing consistency between target motion, lighting state and test vehicle behavior is critical. A brake light event, turn signal activation or lane-change indication must occur in coordination with target trajectory, speed profile and scenario timing to ensure repeatable and meaningful test results.

The upgraded PRIAUTO 3D Passenger Vehicle Target features a wireless interface that allows seamless synchronization with different motion platforms. This enables coordinated control between the target’s movement and its lighting functions, supporting more realistic and repeatable dynamic scenarios.

For example, the target can activate brake lights while decelerating, trigger turn signals before lateral movement, or maintain position lights during night-time following scenarios. This synchronized behavior helps testing teams reproduce real traffic interactions with higher fidelity and improves the consistency of repeated tests.

The enhanced 3D Passenger Vehicle Target can be used across a wide range of vehicle-to-vehicle test scenarios, including:

Compared with conventional vehicle targets, the upgraded target provides a more complete representation of real traffic participants by combining 3D geometry, multi-sensor detectability, lighting behavior and wireless motion synchronization. This enables test engineers to evaluate not only whether a system can detect a vehicle, but also whether it can understand the vehicle’s behavior and respond appropriately in time-critical scenarios.

As intelligent driving functions move toward higher levels of automation, testing requirements are expanding from simple target detection to behavior-aware scene understanding. Future vehicle targets must support more complex interactions, more diverse environmental conditions and more realistic dynamic cues.

PRIAUTO’s upgraded 3D Passenger Vehicle Target addresses this trend by providing a high-fidelity vehicle surrogate that can support both standard ADAS tests and advanced scenario-based validation. Its lighting system enhances visual realism, while wireless synchronization improves dynamic scenario control. Together, these capabilities provide a stronger technical foundation for repeatable, high-confidence safety validation.

The next stage of ADAS and automated driving validation requires test targets that are closer to real traffic objects in both appearance and behavior. By integrating full lighting functions and wireless synchronization into its 3D Passenger Vehicle Target, PRIAUTO provides a more advanced solution for evaluating active safety systems under complex, night-time and low-visibility conditions.

PRIAUTO will continue to develop high-fidelity test targets, intelligent motion platforms and integrated validation tools to support the global automotive industry in building safer, more reliable and more intelligent vehicles.
