【文章內(nèi)容簡介】 S control strategy are built with Matlab and AMESim software platform, which are cosimulated, the influence of related ponents characteristic parameter of the hydraulic adjusting unit on pressure change rate and the correlation between high velocity switch valve control signal and its critical frequency are verified. A research is made to ABS hydraulic adjusting unit made by an overseas pany in rig test, in which the effective adjustment range of PWM signal duty cycle in a certain control period is derived.Key words: ABS。 Hydraulic control system。 Pressure change。 Research《汽車技術(shù)》雜志 2022 年第 9 期8并聯(lián)混合動力轎車傳動比初選方法鐘再敏 馬勇（同濟(jì)大學(xué)）【摘要】通過分析，對混合動力汽車傳動比的選擇給出了初步結(jié)論：從動力性角度出發(fā)，當(dāng)動力源工作在最大功率點時，恰當(dāng)選擇傳動系統(tǒng)的總傳動比，使得汽車能夠達(dá)到最高設(shè)計車速，選擇此時傳動比為最小傳動比；綜合考慮最大爬坡度、附著率及汽車最低穩(wěn)定車速 3 方面的問題確定最大傳動比；最大和最小傳動比之間的中間擋位應(yīng)按照等比級數(shù)分配傳動比的原則進(jìn)行分配。關(guān)鍵詞：并聯(lián)混合動力汽車，傳動比，動力性The Method of Drive Ratio Configuration for Parallel Hybrid CarZhong Zaimin1 Ma Yong1(Tongji University)【Abstract】A primary conclusion is given for the selection of drive ratio of hybrid car based on analysis: from the dynamic point of view, when the power source operates at the maximum power point, selecting appropriately the overall drive ratio of the driveline, which enables the vehicle to obtain the maximum design speed, the drive ratio selected at this moment is the minimum drive ratio。 define the maximum drive ratio based on the maximum gradient, adhesion rate and the minimum vehicle stable speed。 the intermediate gear between the maximum and minimum drive ratio shall be assigned according to the principle of geometric sequence drive ratio assignment.Key words: Parallel hybrid vehicle。 Drive ratio。 Dynamics《汽車技術(shù)》雜志 2022 年第 9 期9基于 ADAMS/CAR 的某輕型載貨汽車前懸架仿真分析黃東明 1 王良模 1 井廣紅 2 尹春華 2 王森 2（； ）【摘要】利用Adams/Car軟件建立了某輕型載貨汽車雙橫臂獨(dú)立前懸架系統(tǒng)動力學(xué)模型，并選取雙輪同向激振工況進(jìn)行了仿真，分析了車輪跳動過程中參數(shù)變化對懸架性能的影響。結(jié)果表明，前懸架的主銷橫向偏移距偏大，容易發(fā)生制動跑偏，前束變化不合理；車輪跳動過程中輪距變化較大，會引起兩側(cè)輪胎方向相反的側(cè)偏運(yùn)動，導(dǎo)致輪胎磨損，同時影響汽車的操縱穩(wěn)定性。主題詞：載貨汽車 雙橫臂獨(dú)立前懸架 仿真分析Simulative Analysis of Front Suspension of A Light Duty Truck Based on ADAMS/CARHuang Dongming1, Wang Liangmo1, Jing Guanghong2, Yin Chunhua2, Wang Sen2( University of Science and Technology。 IVECO Motor Company Ltd)【Abstract】A dynamic model of a wishbone front suspension system for a light duty truck was built with software Adams/Car, and the parallel wheel travel was chosen and simulated, the influence of parameter change on suspension performance during wheel bounce was analyzed. The results show that excessive high kingpin transverse offset of the front suspension leads to braking deflection and improper toein variation。 while the excessive change of the track during wheel bounce leads to slip of the tires to opposite direction, and leads to tire wear, handling stability of the vehicle will be adversely affected.Key words: Truck。 Wishbone front suspension。 Simulative analysis《汽車技術(shù)》雜志 2022 年第 9 期10重型載貨汽車動力傳動系統(tǒng)參數(shù)優(yōu)化匹配王 鐵 1 武玉維 1 李萍鋒 1 鄭利鋒 2 王曉 2( ；）【摘要】針對某重型載貨汽車油耗過高問題，利用仿真軟件 AVL—Crusie建立了整車性能仿真模型，采用 MATLAB 軟件建立了數(shù)學(xué)分析方程，并集成到優(yōu)化平臺 ISIGHT 軟件中，對汽車動力傳動系統(tǒng)的速比參數(shù)進(jìn)行了優(yōu)化設(shè)計和匹配。結(jié)果表明，經(jīng)優(yōu)化設(shè)計后，在滿足汽車動力性各項設(shè)計指標(biāo)的前提下，該車輛驅(qū)動功率損失率降低了 %，6 工況循環(huán)油耗降低了 %。主題詞：重型載貨汽車 傳動系參數(shù) 優(yōu)化The Parameter Optimized Matching of Powertrain for Heavy Duty TruckWang Tie1, Wu Yuwei1, Li Pingfeng1 ,Zheng Lifeng2,Wang Xiao2（1.
