正故障现象一辆2012年产现代伊兰特车,行驶里程约为7万km。因ABS故障灯有时亮有时不亮来厂里维修。故障诊断接车后维修人员对该车故障进行验证,打开点火开关起动发动机,约过2 min后,ABS故障灯点亮。据驾驶人反映,车辆行驶一段时间后,ABS故障灯可能会自动熄灭,于是,维修人员上路试车,经过一段颠簸路面后,ABS故障灯果然熄灭了,但过了一会儿后,ABS故障灯又再次亮起。 相似文献

汽车ABS系统一旦发生故障后,通知故障自诊断系统得以保存,利用故障警告灯诊断和快速检查方法,就能快速诊断排除。ABS系统故障隐蔽,难于发现,其故障代码的提取要求技术性强,因此,分析、研究ABS系统的故障检测的方法,对于维修人员提高维修技术水平,准确快速地排除汽车ABS系统故障具有一定的参考意义。 相似文献

ABS报警灯的作用是监测ABS系统的工作情况,在发动机起动过程中,ABS报警灯应点亮,但是在自诊断系统确认ABS系统工作正常后,ABS报警灯即会熄灭。如果ABS报警灯仍然点亮,说明ABS系统存在故障。在对系统诊断与维修完毕后,应按照以下方法,将ABS报警灯复位。 相似文献

ABS属于汽车安全装置,故其警告灯电路比其他电路复杂,加上由于当前所采用的电路类型繁多,故ABS部分电路的作用及维修在当前维修业界成为难点之一。在索那塔EF车上采用了active型ABS电路,其特点是电子化电路,配置于仪表板后侧,从而大大简化了以往的主要由继电器、开关、接头、配线所构成的电气系统,从而改善了维修作业。 相似文献

汽车的制动性能关系剑汽车安全行驶性能。ABS防抱死系统的应用是汽车安全性方面最重要的技术进展。通过对装备ABS汽车与普通汽车制动距离的计算比较分析发现,在湿滑的道路上突然制动,ABS系统可以使驾驶员能够保持车辆行驶平稳,在较短的距离内将汽车刹住。但在不湿滑的路面上,缩短刹车距离的范同值比较小。而在冰雪路面上行驶的车辆,没有装备ABS的汽车在湿路面或冻路面上制动时,制动距离会过长且不能猛烈转向。而装备ABS系统的汽车也是如此,因为尽管ABS能提供附加的制动控制和转向控制,但它不能解决这样一个客观的物理事实:那就是在较滑的路面上,可利用的牵引力很小。 相似文献

现在汽车上采用的ABS产品都采用逻辑门限值控制方式,以德国BOSCH公司开发的ABS产品为例,详细阐述了这种控制方式的控制过程,然而逻辑门限值控制方式对于不同车型的逻辑门限值的要求有所不同,因此通用性能差。这里介绍了一种自适应的PID控制方式,在模型未知的情况下能很好地调整比例、微分、积分三个参数,将其应用于ABS上,可获得更好的制动效果。 相似文献

Improvement of drivability and fuel economy with a hybrid antiskid braking system in hybrid electric vehicles 总被引:1,自引:0,他引:1

When braking on wet roads, Antilock Braking System (ABS) control can be triggered because the available brake torque is not
sufficient. When the ABS system is active, for a hybrid electric vehicle, the regenerative brake is switched off to safeguard
the normal ABS function. When the ABS control is terminated, it would be favorable to reactivate the regenerative brake. However,
recurring cycles from ABS to motor regenerative braking could occur. This condition is felt to be unpleasant by the driver
and has adverse effects on driving stability. In this paper, a novel hybrid antiskid braking system using fuzzy logic is proposed
for a hybrid electric vehicle that has a regenerative braking system operatively connected to an electric traction motor and
a separate hydraulic braking system. This control strategy and the method for coordination between regenerative and hydraulic
braking are developed. The motor regenerative braking controller is designed. Control of regenerative and hydraulic braking
force distribution is investigated. The simulation and experimental results show that vehicle braking performance and fuel
economy can be improved and the proposed control strategy and method are effective and robust. 相似文献

The effectiveness of ABS for the motorcycle has been evaluated by comparison with deal braking. However, it is almost impossible for the typical rider to perform ideal braking in an emergency. We conducted braking in a turn test by skilled and less-skilled riders, for the purpose of evaluating the effectiveness of ABS for the typical rider and obtaining data for a method of evaluating motorcycle ABS performance. It was shown that ABS for the motorcycle is effective for both skilled and less-skilled riders in terms of braking distance and vehicle stability. 相似文献

An Antilock Braking System (ABS) is one of the most important safety facilities equipped in modern vehicles. A self-test is
therefore embedded into its ECU to identify any electronic malfunction. However there is no effective method to predict or
check its mechanical conditions routinely to ensure its functionality. Because the ABS system is merely actuated above a particular
speed in emergency stops, the current brake test facilities are not adequate for ABS test. Because of the dangers involved
it would not be acceptable to use a public road to implement such a practice for fault detection so an alternative means must
be sought. To provide a safe and convenient solution this paper proposes a novel method to predict ABS faults whilst the vehicle
is stationary. In this situation a model-based approach is applied to predict various faults from the ABS, especially from
its hydraulic subsystem. As such, a mathematic model is developed to describe the operating processes of ABS including possible
faulty conditions. An autonomous control strategy is also designed to actuate the control module independently without the
knowledge of the control algorithms embedded in an ABS control module. This approach is evaluated through a Simulink simulation. 相似文献
