| 摘 要： | 文章结合电涡流缓速器和再生制动能量回收技术的优点,提出了能量回收式电涡流缓速器制动补偿策略。利用再生制动系统提供的制动力矩为电涡流缓速器在持续制动过程中的制动力矩热衰退予以补偿。以GB12676-2014政策法规为验证标准,车辆在满载情况下在7%的坡道上保持以30km/h的车速匀速行驶5km为仿真目标,对某商用车型进行仿真分析。验证了该策略使得实际产生的总制动力矩始终能满足驾驶员的制动需求,可以延缓电涡流缓速器温升,保障车辆行车安全。

| Abstract: | Combining the advantages of the eddy current retarder and regenerative braking energy recovery technology,the braking compensation strategy of the energy recovery type eddy current retarder is put forward.The regenerative braking system is used to compensate the thermal decline of the braking torque during the continuous braking of the eddy current retarder.Taking gb12676-2014 policies and regulations as the verification standard,the vehicle maintains a speed of 30km/h at a constant speed of 5km on a 7%ramp under full load as the simulation target,and carries out simulation analysis on a commercial vehicle.It is verified that the actual total braking torque can always meet the driver's braking demand,and can delay the temperature rise of eddy current retarder to ensure the vehicle driving safety. |
