The event-tracking data of intelligent cockpit contains rich information about driver and passenger actions. Analyzing and identifying specific action intents can benefit deeper insights into user needs. Considering the high cost, strong subjectivity, and repetitiveness of current methods that rely on manual tagging for action intent recognition, a new method based on Artificial Intelligence model for automated tagging and classification is proposed. By fine-tuning the Qwen2-14B model, this approach could rapidly identify action intents across multiple dimensions and granularities, enhance the efficiency of cloud data analysis and lay a theoretical foundation for real-time response to user needs on the vehicle side.

To enhance lateral active safety in intelligent connected vehicles, the identification and definition of unintended functional safety scenarios for the Electric Power Steering (EPS) system are integrated into system design and development process. By combining scenario domain analysis, equivalence partitioning, and boundary value analysis with the deconstruction of vehicle model variants and lateral motion scenarios related to EPS, more potential hazardous operational scenarios are expanded from known operational scenarios. Meanwhile, the Driver-In-the-Loop (DIL) system based on hardware-in-the-loop simulation is utilized. Relying on its advantages of “driver-vehicle-environment” closed-loop, more unknown risk scenarios are transformed into valid known scenarios. Subsequently, the existing safety technical requirements are optimized and the overall performance of the EPS system is further improved.

To optimize the opening and closing forces of the automotive Power Lift Gate (PLG) system, the literature on algorithms related to lift gate forces is reviewed, and a mechanical model of the lift gate system is established. The expressions for the moment exerted by the support rod on the lift gate and the moment exerted by gravity on the lift gate are derived, and the relationships between the length of the support rod, the force arm of the support rod, and the opening angle are analyzed. A simulation model is created using simulation software to perform calculations, and the rationality of the expressions is verified. This study provides a theoretical foundation and optimization direction for the design and improvement of PLG systems.

Electric Vehicles (EVs) are more prone to inducing motion sickness compared to traditional vehicles. To investigate the factors contributing to motion sickness in EVs and their differences from traditional vehicles, and to propose effective mitigation and treatment methods, process and mechanism of motion sickness induction in EVs is explored by analyzing factors such as EVs’ structural characteristics, power output, and regenerative braking systems. Mitigation methods, including medical medications, structural optimization, and aroma regulation are also considered. Meanwhile, subjective questionnaires and objective physiological data are compared as methods for testing motion sickness. The research results indicate that EVs are more likely to induce motion sickness due to their robust power output characteristics and the repeated pulling sensation caused by the regenerative braking system. Existing mitigation methods have shown varying degrees of effectiveness across different individuals. Additionally, the study offers insights and prospects for future research on managing motion sickness in EVs, contributing to more effective solutions.

In order to enhance the safety of vehicles equipped with air suspension and to prevent injuries to road users caused by air suspension failures during operation, a functional safety analysis of the air suspension system is conducted. Based on the ISO 26262 functional safety standard, relevant items of the air suspension system are defined, and a hazard analysis and risk assessment method are used to derive the functional safety objectives for the air suspension. These functional safety objectives are then decomposed step by step to the subsystem and hardware/software levels, establishing a complete safety architecture. Combining the vehicle rollover theoretical model, the risk of vehicle rollover is analyzed, along with the impact of air suspension height adjustment on the roll moment arm and lateral load transfer rate. A graded response mechanism is proposed: if the suspension fails but there is no rollover risk, an alarm is triggered and continuous monitoring is maintained; if there is a rollover risk, the height adjustment function is forcibly stopped to ensure the system enters a safe state. The designed strategy effectively balances functional safety with system availability, ensuring the functional safety of the air suspension and the overall stability of the vehicle.
