In order to solve the problems of low efficiency and large tracking errors in outdoor unmanned forklift path planning, a kinematic model of outdoor unmanned forklift is established. By constructing a path cost function and combining simulated annealing optimization, redundant nodes are removed to improve the search efficiency and path smoothness of the A* algorithm. On this basis, with speed and heading angle as input variables, a fuzzy controller is designed to dynamically adjust the preview distance of the pure tracking algorithm, and simulation and real vehicle experiments are carried out. The results indicate that the improved A* path planning algorithm reduces path length by 4.5% and turns by 98.7%. The dynamic preview distance pure tracking algorithm using fuzzy control reduces the maximum error by 58.7% in curve tracking, significantly improves path smoothness and tracking accuracy, and can be effectively applied to complex industrial application scenarios.

2026, 51(8): 8-15. DOI: 10.16638/j.cnki.1671-7988.2026.008.002

Abstract ( )

PDF (849KB) ( )

To address the problem that target vehicle trajectory prediction in complex traffic environments exhibits multi-modality and uncertainty, making it difficult for traditional model predictive control (MPC) to effectively utilize prediction information, a probabilistic risk prediction– based control method is proposed. The multi-modal trajectory prediction results are modeled in the probabilistic space to construct state probability distributions and extract their statistical characteristics. A confidence ellipsoidal risk envelope is generated and incorporated into the MPC framework as risk constraints. Experimental results demonstrate that the proposed method can effectively avoid collision risks while improving trajectory smoothness in complex scenarios, providing a feasible and generalizable solution for prediction-driven safety decision-making control of intelligent vehicles.

Abstract ( )

PDF (1272KB) ( )

With the rapid development of new-energy vehicles, extending driving range and improving energy efficiency have become critical challenges. Predictive cruise control (PCC) leverages upcoming road information to optimize longitudinal control, thereby reducing energy consumption while enhancing driving comfort. Unlike previous studies that mainly focus on algorithmic improvement in simulation, this paper presents an engineering-oriented design framework that explicitly targets the constraints of an on-board vehicle control unit. The framework consists of three modules: environmental perception, path prediction, and control decision. By integrating dynamic programming (DP) with road-segment reconstruction, the system generates an optimal speed trajectory while fully utilizing grade-preview data. Simulation results over a mountainous highway scenario show a 3.24% reduction in energy consumption compared with a baseline human-driving profile. The results provide new insights and an engineering-ready reference for the subsequent real-vehicle implementation of intelligent energy-saving control in new-energy vehicles.

PDF (1616KB) ( )

Aiming at the heterogeneous dual e-drive axle system composed of a distributed e-drive axle and a centralized e-drive axle, this paper proposes an inter-axle torque distribution control method based on instantaneous system efficiency optimization. The method first determines the system's maximum speed and peak driving force boundaries, constructs a comprehensive efficiency storage matrix. Then traverses all working conditions through a main speed loop and a driving force sub-loop. Then within the sub-loop, the driving force demand for each axle is calculated based on a preset wheel-edge force distribution ratio. Within their peak capability ranges, motor efficiencies are obtained by querying motor efficiency MAP, and the overall system efficiency is computed. Finally, the optimal system efficiency under each speed–total driving force operating point is screened and stored, along with its corresponding wheel-edge force distribution ratio, axle-specific wheel-edge forces, motor speeds, motor torques, and efficiencies. This method provides a theoretical basis for efficient cooperative control of heterogeneous dual e-drive axles.

2026, 51(8): 54-60. DOI: 10.16638/j.cnki.1671-7988.2026.008.010

Abstract ( )

PDF (1879KB) ( )

To address the engineering challenge of balancing multiple conflicting performance objectives with lightweight requirements in the design of automotive rear hub brackets, this paper proposes a multi-objective topology optimization method based on the compromise programming approach. A maximum design space model is constructed based on suspension hardpoints, and a multi-objective optimization model is formulated with volume fraction and critical hardpoint stiffness as constraints, aiming to simultaneously minimize structural compliance and maximize the first natural frequency. Unlike conventional weighted sum methods, the compromise programming approach effectively resolves the non-convex conflicts between stiffness under multiple load cases and natural frequency by seeking a compromise solution with the shortest distance to the ideal point, thereby enabling rational material distribution. The optimization is performed using OptiStruct, followed by structural reconstruction and iterative design in Siemens NX. The validation results show that the optimized bracket exhibits superior stiffness at all hardpoints compared to the benchmark model, with a maximum stress of 201 MPa under extreme conditions, satisfying strength requirements. The mass is reduced from 5.27 kg to 3.15 kg, achieving a 40.2% weight reduction. The proposed method provides a transferable engineering pathway for the synergistic design of high performance and lightweight in critical chassis components.

PDF (1283KB) ( )

In the line-haul logistics market for heavy-duty commercial vehicles, the trend toward high power paired with low speed ratios is becoming increasingly pronounced. To strike a trade-off point of customers power demands for high power with the pursuit of ultimate fuel efficiency for vehicles, this paper proposes an innovative method for assessing customers power needs across different power models. This approach is based on massive existing vehicle operation data. Specifically, it calculates the average operating power of vehicles within the same market segment and under identical operating conditions. The increase in this average power is used to quantify customers' psychological expectation for power improvement as power increases. Combining actual operating conditions, the optimal power matching is recommended. Analysis shows that under plain freeway condition and mountainous freeway condition, a unit power increase in corresponds to a rise in customer power demand of 0.09% and 0.12%, respectively. The findings indicate, in climb conditions, an 17 L, 588 kW model consumes 1.15 L/100 km less fuel and achieves a 7.9% higher speed than a 15 L, 500 kW model; under comprehensive conditions, the 17 L, 588 kW model maintains similar fuel consumption while achieving a 6.9% higher average speed than 15 L, 500 kW model.

Mechanism Research on Powertrain Impact Noise during Transient Clutch Disengagement in Reverse Gear for a Coach

ZHAO Xuan, CHEN Xiaoli, MA Husen

2026, 51(8): 80-85. DOI: 10.16638/j.cnki.1671-7988.2026.008.015

Abstract ( )

PDF (2038KB) ( )

This paper addresses the problem of severe impact noise induced in the powertrain of a manual-equipped coach during transient clutch disengagement in reverse gear. A comprehensive dynamic model of the powertrain is developed using AMESim, which integrates the engine, transmission, drive shaft, rear axle and the lumped inertia of the entire vehicle. Combined with vehicle-level noise, vibration, harshness (NVH) test data, the underlying mechanism of the impact noise is revealed. The abnormal noise is primarily caused by the alternating switching between driving and driven conditions on the meshing interfaces of gears and splines along the power transmission path. Moreover, the impact response occurs earlier in the rear components of the powertrain than in the front components. Using the speed difference of the reverse idler gear as an evaluation index, simulation analyses are conducted to investigate the effects of clutch disengagement rate and internal clearances in the transmission on impact noise characteristics. Both simulation and experimental results demonstrate that lowering the clutch disengagement rate can significantly attenuate the powertrain impact noise. Gears located on the non-powertransmission paths of the transmission exert no influence on the impact noise. Merely reducing the backlash of transmission gears and splines provides only a limited improvement in suppressing the powertrain impact noise.

With the rapid development of the new energy vehicle industry, as a core component of the drive motor system, the training of its disassembly, assembly and maintenance skills is particularly important. However, training in the disassembly and maintenance of drive motor systems generally faces prominent issues such as high susceptibility to damage of precision parts, limited practical training space, difficulty in disassembling and assembling complex components, and restrictions on training scale. To address these challenges, this article takes the Volkswagen ID.4 CROZZ drive motor system as the research object. The three-dimensional model construction and optimization of the drive motor are completed through Blender, and the model is imported into the Unity3D platform to design and develop the virtual assembly system of the drive motor. The model is then imported into the Unity3D platform to design and develop a virtual assembly system for the drive motor. This system not only provides cognitive learning of component structures but also supports interactive manual disassembly and assembly operations of the motor drive system. It intuitively demonstrates the core structure and assembly process of the motor, significantly enhancing users' understanding and operational skills. This virtual system helps overcome the limitations of traditional training models in terms of resources, space and efficiency, providing innovative technical support for the cultivation of technical talents related to new energy vehicles.
