现在宝马车系都带idrive系统了,知道一个idrive车型的刹车片复位方法就应该知道其它系列的操作,处理起来都差不多。下面由朗仁科技丁联辉工程师介绍更换刹车片后,怎样都不能复位的原因与相应处理方法:
必须满足以下三个条件,方可复位成功:
– 不存在检查控制信息(即仪表上的黄色三角符号)
– 刹车片感应线必须是新的
– 车载时钟,日期必须正确调整
一、传感器功能描述:
技术信息
制动摩擦片磨损传感器在拆卸后务必更新,因为制动摩擦片磨损传感器失去其在新制动摩擦片中的固定能力。
如果在尚未达到制动摩擦片的最小厚度时必须更换一个已经磨削的制动摩擦片磨损传感器,必须注意下列事项:新的滑动触头必须用锉子锉到与已磨销的滑动触头相同的长度。
左前和右后制动摩擦片磨损传感器
左前和右前制动摩擦片磨损传感器分别固定在制动钳上。
制动摩擦片状态由 DSC 控制单元计算 (制动压力、时间、温度),通过制动摩擦片磨损传感器核实计算。
功能描述
制动摩擦片磨损传感器是具有电阻测量功能的传感器。
制动摩擦片磨损传感器 (左前和右后在内部制动摩擦片上) 提供制动摩擦片厚度辅助信息。
此制动摩擦片磨损传感器设计成 1 档。如果导体电路已经被磨损,则会有约 5 % 的制动摩擦片剩余厚度。这与约 2500 公里的剩余里程相符。
临界制动摩擦片厚度将在组合仪表中通过保养周期显示 (车况保养 CBS) 以及制动报警灯呈红色显示。
结构及内部电路连接
制动摩擦片磨损传感器,一级式:如果导体电路已经被磨损,则会有约 5 % 的制动摩擦片剩余厚度。
线脚布置(制动摩擦片磨损传感器通过 DSC 控制单元供电)
标准值
注意制动摩擦片磨损传感器的下列标准值:
安装注意事项:
打开壳体盖,检查①插针连接状态(深孔接触良好)
注意安装好新的制动摩擦片磨损传感器②(牢固)、在制动摩擦片中和支架 ① 中的位置是否正确。
诊断提示
部件失灵(无法复位)
制动摩擦片磨损传感器失灵时,预计将出现以下情况:
· 动态稳定控制系统内出现故障代码存储记录
· DSC 为组合仪表中的保养周期显示计算保养范围作为替代
· 断路时控制制动报警灯
服务功能
注意!
保养范围 “前部制动摩擦片” 和 “后部制动摩擦片” 只有通过一个未磨损的制动摩擦片磨损传感器进行复位。
在车型诊断功能内复位:
用朗仁产品H6做15年宝马X3的制动片保养复位,首先已更换制动片和感应线。
Ø 诊断功能找到“宝马”,自动选择读取进入后,选择CBS(保养)复位—前制动片复位—点击复位。
二、技术通报一列:
计算出的 CBS (车况保养) 数据 “制动摩擦片” 的剩余里程不可信
涉及车辆:
序列 F10 F11 F12 F13 F18 F20 F25 F30 F35
以及部分E系车辆。
投诉:
计算出的制动摩擦片 (前桥和/或后桥) CBS 数据的剩余里程与实际制动摩擦片厚度不一致。客户注意到在前轴制动摩擦片和/或后轴制动摩擦片上的剩余里程不可信 (太高或太低)。特殊情况下尽管制动摩擦片足够厚,仍会输出黄色警告信息 “下期保养到期” (前轮/后轮制动器)
只要黄色灯 “保养到期” 不亮起,就不需要进行处理。
原因:
DSC (动态稳定控制系统) 控制单元中的软件或应用程序。
处理措施:
处理客户投诉时不要进行维修 – 也不要复位车况保养
Ø 手动修正制动摩擦片厚度或通过测试仪功能进行复位只能暂时排除投诉,手动修正后,可能顾客会再次遇到同样的问题。
Ø 以原厂诊断服务功能规定的顺序完整执行操作(含重新编设码)
只要黄色灯 “保养到期” 不亮起,就不需要进行处理。
自 2013 年 3 月后起执行的软件措施可供使用!
故障投诉:
故障位置 故障类型
前轮制动器显示服务 显示错误 / 不可信
前轮制动器显示服务 警告 / 显示已启动
后轮制动器显示服务 显示错误 / 不可信
后轮制动器显示服务 警告 / 显示已启动
检查控制信息:

附:制动片的小知识
制动片功能
制动片在高摩擦、高温的环境中工作,通过对制动盘的相互摩擦,达到车辆制动减速的目的。制动摩擦片也叫刹车片、刹车皮,具有摩擦性、抗烧蚀性、隔热性、降噪性、环保性。
不及时更换制动片的危害
制动片随着制动频率的增长会逐渐变薄,未及时更换,容易造成以下危害:
– 制动行程加大、制动反应速度变慢,制动距离变长;
– 制动片的摩擦材料磨损过度容易造成制动片底板与制动盘直接摩擦,导致制动盘报废
制动片更换标准:
– 制动片摩擦材料摩擦极限通常为3mm;
– 同轴的制动片以最薄一片作为更换的最低标准
– 为保障制动效果,同轴的制动片必须同时更换
