    摘要:

    為了深入研究電磁與摩擦集成制動(dòng)系統(tǒng)防抱死控制機(jī)理,,提高其在緊急制動(dòng)下的防抱死控制性能,,在建立電磁與摩擦集成防抱死制動(dòng)模型的基礎(chǔ)上,,根據(jù)電磁制動(dòng)與電子液壓制動(dòng)各自制動(dòng)控制特性,,提出了電磁與摩擦集成制動(dòng)系統(tǒng)防抱死制動(dòng)分層協(xié)調(diào)控制方法,。在硬件在環(huán)仿真平臺(tái)上驗(yàn)證了數(shù)學(xué)模型的有效性,,并在模擬干燥瀝青路面、冰雪路面以及對接路面環(huán)境下,,對比研究了電磁與摩擦集成制動(dòng)系統(tǒng),、高性能電子液壓制動(dòng)系統(tǒng)和低性能電子液壓制動(dòng)系統(tǒng)的防抱死制動(dòng)性能,。結(jié)果表明:在防抱死控制過程中使用電磁制動(dòng)取代低性能電子液壓制動(dòng)系統(tǒng)控制車輪最佳滑移率,僅使用低性能電子液壓制動(dòng)提供一定的制動(dòng)強(qiáng)度,,完全可以實(shí)現(xiàn)與高性能電子液壓制動(dòng)系統(tǒng)相同甚至更優(yōu)的防抱死控制效果,。

    Abstract:

    In order to study the anti-lock braking control mechanism of the electromagnetic and frictional integrated brake system and improve the anti-lock braking control performance, the anti-lock braking model was established. And the layered coordinated antilock control method was put forward according to the braking control features of electromagnetic brake and electronic hydraulic brake. The hardware in the loop simulation platform of electromagnetic and frictional integrated brake system was used to verify the validity of this mathematical model. The comparative study which simulated the dry asphalt, ice and snow and docking pavement was carried out on the anti-lock braking performance of electromagnetic and frictional integrated brake system, high-performance and low-performance electronic hydraulic brake system. Conclusions are obtained as follows: using the electromagnetic brake to control the optimal slip ratio in the process of antilock control could fully realize the same anti-lock control effect of high-performance electronic hydraulic brake system with a certain amout of braking intensity provided by low-performance electronic hydraulic brake system. In the design process of the electromagnetic and frictional integrated brake system, the reasonable match of braking performance of electromagnetic brake and electronic hydraulic brake minimizing reliance on the hydraulic control elements of the electronic hydraulic brake would reduce the manufacturing difficulty and cost of the electromagnetic and frictional integrated brake system.
