Description

一种轮胎监测系统 技术领域
本发明涉及汽车行车安全技术领域,特别涉及轮胎气压、 温度监测与 行车控制技术， 具体指一种轮胎监测系统。 背景技术
轮胎对汽车行车安全的影响一直受到汽车业界和社会公众的关注，美 国于 2003年开始强制实施轮胎气压监测系统（TPMS )为汽车标准配置后， TPMS已经成为汽车技术专有名词，世界范围内的 TPMS研发生产出现快速增 长趋势。
现有 TPMS的主流技术方案是： TPMS由两部分組成：安装在汽车轮胎里 的远程轮月台压力监测模块（RTPM： Remote Tire Pressure Moni toring ) 和安装在汽车驾驶台上的中央监视器（LCD显示器）。 安装在每个轮胎内 的远程压力监测模块由锂亚电池供电， 对轮胎压力和温度进行监测采样， 采样数据通过高频无线电波 F )发射， 一套 TPMS系统有 4个或 5个（包括 备用胎） RTPM模块。 中央监视器接收远程轮胎压力监测模块发射的信号， 将各个轮胎压力和温度数据依次显示在液晶屏上，供驾驶员参考。如果轮 胎压力或温度出现异常，中央监视器根据异常情况，发出不同的报警信号， 提醒驾驶者采取必要的措施。 其典型技术路线或原理框图如图 1所示。
其中， 远程轮胎压力监测模块由多个部分组成： （1 )具有压力、 温 度、 加速度、 电压检测和后信号处理 ASIC芯片组合的智能传感器； （2 ) 4 - 8位单片 （MCU )； ( 3 ) RF射频发射芯片； （4 )锂亚电池； （5 )天 线。
智能传感器是硅显微机械加工（MEMS )技术制作的片上系统模块， 包 括压力传感器、 温度传感器、 加速度计、 电池电压检测、 内部时钟和一个 包含模数转换器（ ADC )、取样 /保持（ S/H )、 SPI口、校准（ Cal ibrat ion )、 数据管理（Data )、 ID码的数字信号处理 ASIC单元， 模块具有掩膜可编程 性， 即客户可以利用专用软件进行配置。
现有技术 TPMS采用鋰亚电池对 RTPM供电， RTPM由于受电池容量的制 约， 电池管理的最小化功率设计采用采样后睡眠和定时唤醒方案， 以满足 电池使用 5 ~ 10年时间的要求。 在 TPMS方式下， 压力温度等数据采用大间 隔采样的方式， 一般地， 压力数据采样频率为 l/3Hz ~ l/8Hz, 数据发送频 率为 l/30Hz ~ l/80Hz, 由 RTPM微处理器电源管理程序进行精确控制， RTPM 定时唤醒时间间隔一般固定设置为 3 ~ 8秒范围， 两次采样间隔期间 RTPM 模块处于睡眠状态。
TPMS对保持轮胎正常气压、 预防和减少爆胎事故具有积极作用和效 果。但现有的 TPMS系统由于轮胎气压数据采样间隔达 3000 ~ 8000毫秒， 而 存在一定的局限或缺陷， 仅有轮胎气压、温度信息提示功能， 作用局限在 预警预防方面，无法对突发的爆胎或快速泄气即时作出响应和提供有效救 助， 这是现有技术 TPMS的特征。从严格意义上说， 现有 TPMS应定义为信息 提示预警系统。
现有相关研究资料表明，爆胎是突发性事件， 事前无明显或确定的征 兆， 无法从根本上避免。 引发爆胎的原因是轮胎气体压力、 温度升高， 特 别是轮胎气压偏低引发的轮胎内部（橡胶与钢丝帘布间）摩擦，造成轮胎 橡胶层局部高温， 橡胶与帘布层剥离、脆化， 最终导致轮胎爆裂。 轮胎气 压偏低、 长时间高速行驶是爆胎的重要诱因。
美国学者 Wesley D. Grimes发表的 《车辆对爆胎反应的三维仿真》 ( 3 - Dimens ional Simul tion of Vehicle Response to Tire Blow-outs ) 研究报告表明， 爆胎发生时， 胎内气压在 100亳秒内丧失， 爆胎车轮滚动 半径减小、爆胎车轮滚动,阻力增加为爆胎前的 30倍以上，爆胎车轮和处于 对角线位置的车轮对地面的正压力 Fz下降，侧向摩擦力也随之下降， 过程 继续则爆胎车轮出现轮辋对轮胎的碾压， 碾压直至轮胎撕裂与轮辋分离， 导致侧向摩擦力大幅下降。在轮胎被碾压和撕裂的过程中，轮胎与地面滚 动阻力大幅增大甚至导致车轮由滚动转为滑动（当爆胎车轮为从动轮时）， 形成一侧向作用力， 使汽车发生偏离行驶方向的运动。
Wes ley D. Grimes的研究报告同时表明， 单纯的爆胎并非必然导致事 故的发生，驾驶员对爆胎信息作出的反应操作是否正确和爆胎时车辆所处 的具体路况，对爆股后是否引发交通事故有直接关联，特別指出驾驶员过 度转向和过度制动（制动抱死）均有可能导致事故的发生， 相反， 驾驶员 适当的操控（调整维持行驶轨迹和适度制动） ， 将可能避免事故的发生。
该研究报告结论揭示了一个极为重要的事实：在爆胎发生 2 ~ 3秒后 的时刻， 驾驶员能够做出反应时间起， 驾驶员对汽车的适度操控仍然被认 为是必要的和必需的， 对化解爆胎危险具有重要作用。 发明内容

图 1为现有 TPMS技术方案框图；
图 2为本发明技术方案框图；
图 3是本发明技术方案控制程序流程图。
具体实施方式
以下 居附图对本发明技术方案的实施作具体说明。
本发明的技术方案为， 一种轮胎监测系统， 其中包括： 安装在轮胎里 的远程轮胎监测单元、中央控制器、语音提示单元和制动减速机构；其中， 所述的远程轮胎监测单元， 以 5Hz ~ 20Hz的采样频率对轮胎气压进行 监测采样， 并将采样数据包信号无线传输至所述的中央控制器；
所述的中央控制器无线接收所述的轮胎状态采样数据包信号 ,并对接 收的数据包信号进行解码和运算处理， 生成语音提示指令和 /或制动减速 指令，将所述的语音提示指令发送给所述的语音提示单元，将所述的制动 减速指令发送给所述的 ^动减速机构；
所述语音提示单元用于接收所述语音提示指令并输出语音提示信息； 所述制动减速机构用于接收所述制动减速指令并执行制动减速动作。 根据本发明的远程轮胎监测单元包括：传感器，用于对轮胎状态进行 监测采样， 输出采样数据信号； 信号处理单元， 接收并处理所述的禾样数 据信号， 输出轮胎状态数据包信号； 射频发射单元， 对所述的轮胎状态数 据包信号进行发射； 定时唤醒电路单元用于使传感器、信号处理单元和射 频发射单元在两次采样间隔期间睡眠， 降低远程轮胎监测单元电能消耗。
根据所述的系统，所使用的射频频率为微波 315MHz或 433MHz或 866MHz 或其他许可民用微波波段。
如图 2所示，本发明技术方案与现有 TPMS技术方案相比， 在远程轮 胎监测单元 1'部分，保持了 TPMS技术方案的基础。本发明技术方案在 TPMS 的基础上， 保留中央监视器的气压信息预警提示功能，增加行车干预控制 功能,使中央监视器扩展成为中央控制器。由于轮胎气压采样频率的提高， 轮胎远程监测单元可对爆胎或快速泄气等突发信号及时采样并传送，中央 控制器接收到爆胎信号数据后，迅即给出控制指令，驱动行车干预机构实 施制动减速和减小节气门开度措施 , 降低汽车速度以化解爆胎危险。
本发明在轮胎气压采样频率和定时唤醒电路上进行了创造性改进。发 生爆胎等突发事件时，轮胎气压在 100毫秒左右全部丧失，要求气压传感 器监测采样频率与之相适应，将 TPMS现有采样频率 l/3Hz ~ 178Hz提高为 10Hz,确保对泄气时间 100毫秒左右的爆胎气压信号的及时采样。一般地， 采样频率 10Hz是最低下限， 但若牺牲较少的反 时间， 达到大幅度延长 电池使用寿命的目的，仍然是合理和适当的，如本发明的远程轮胎监测单 元 1， (图 2所示）采样频率设置范围为 5 ~ 20Hz。 釆样频率过低不能保证 对爆胎气压信号的及时采样，过高则无谓消耗电能，造成电池使用寿命缩 短。 因此， 例如， 本实施例将采样频率可以设置为 10Hz， 保证对爆胎等 突发事件的轮胎气压数据及时采样。
特别地， 为了降低远程轮胎压力监测模块的电能消耗， TPMS 技术方 案采用两次采样间隔期间使远程轮胎监测单元睡眠的工作模式，并以定时 唤醒方式唤醒，但现有 TPMS远程模块预置固定的 3 - 8秒唤醒一次显然不 能适应高采样频率工作模式， 本发明实施例将模块定时唤醒间隔改进为 50 ~ 200毫秒范围， 例如可设置为 100毫秒， 实现 10Hz采样频率下的两 次采样间隔期间模块睡眠， 达到了高采样频率下的省电功能要求。
除远程轮胎监测单元 1'之外， 本发明的轮胎监测系统还包括： 中央 控制器、语音提示单元和制动减速机构。 该中央控制器包括： 射频接收单 元， 用于接收所述的轮胎状态数据包信号； 信号处理控制单元， 对接收的 轮胎状态数据包信号进行解码和运算处理，生成轮胎状态数据，将所述的 轮胎状态数据与预设的轮胎状态阈值范围进行比较，如果所述的轮胎状态 数据符合预设阁值范围，则输出所述的语音提示指令和 /或制动减速指令。 所述的轮胎状态数据包括： 爆胎或快速泄气数据； 严重缺气数据； 缺气数 据； 正常气压数据和超压数据。
所述的轮胎状态预设阈值范围是指 ·爆胎或快速泄气范围 轮胎正常 气压值 30%; 轮胎正常气压值 30% <严重缺气范围 轮胎正常气压值 60%； 轮胎正常气压值 60 % <缺气范围 轮胎正常气压值 80 %； 轮胎正常气压 值 80% <正常气压范围 轮胎正常气压值 %； 超压范围>轮胎正常气 压值 120 %;
如果轮胎状态采样数据处于 >轮胎正常气压值的 30%范围（该范围数 据称为 "预警数据"）， 则仅输出语音提示指令， 语音提示单元接收到该语 音提示指令后， 以预设的提示频率输出相应语音提示信息；
如果轮胎状态采样数据处于 轮胎正常气压值的 30% (该范围数据称 为 "控制数据 "）， 则输出语音提示指令和制动减速指令。
由于现有 TPMS远程轮胎气压监测模块均来自世界上几个专业性大公 司， 模块的运行程序 （或具体功能指标）设计是以二次开发的方式进行， 因此，本发明在运行程序中气压异常特征点设计上，按照上述轮胎状态预 设阈值范围进行设计， 中央控制器（ECU )对接收到的气压数据进行分析 处理， 将数据按照上述阈值划进行划分。 另外， 气压区域划分依车型、 轮 胎气压差异可作调整，若需要提高气压预警范围精度，可将气压范围作更 多个和更细的划分。
语音间隔提示驱动功能直接由 ECU实现， ECU对接收到的气压采样数据 信息进行运算判别， 达到信息提示条件时，按照设定的时间间隔向语音合 成电路发出驱动信号，语音合成电路预先录制固化相应的语音合成，按照 驱动指令发出语音报警¾示。
本发明技术方案采用语音提示而排除 LCD显示方式， 除了避免过多信 息干扰驾驶员行车安全作用外，也简化了产品的安装难度， 中央控制器安 装在车内适当的隐蔽处， 对汽车的内部装饰不造成任何影响。
中央控制器的信号处理控制单元具有制动减速指令与爆胎气压采样 数据信号随动功能， 爆胎或快速泄气采样数据中断则制动减速指令中断。
自动控制状态下制动减速功能的实现应考虑信号干扰可能造成的误 触发问题，这是采用无线信号传输方式技术方案尤其应注意的问题，在实 际的交通状况中， 汽车可能行驶于任何环境条件下，信号干扰可能招致的 直接后果， 是自动控制系统的误操作， 可能带来误制动的后果。 因此， 必 须考虑或防范可能后果的出现和抑制后果的危害，本发明在 ECU控制程序 上，设计专门的信号干扰误触发抑制程序， 即制动减速指令与爆胎气压采 样数据随动， 爆胎气压采样数据中断时， 中央控制器（ECU) 的制动减速 指令也随即中断， 因此， 个别干扰信号即使造成系统的误制动，也由于干 扰信号不连续或无规律， ECU将很快予以甄别，抑制或消除误制动的影响， 避免误制动持续产生危害后果。
本发明技术方案自动制动减速功能的制动执行机构，可采用现有技术 的自动减速机构，如汽车追尾避撞系统的自动制动减速机构来实现，也可 以设置专门的具有制动力蓄能的制动减速机构，如中国专利 ZL00101579.6 所公开的自动减速机构， 实现自动减速的目的。
本发明的语音提示单元包括语音合成电路，该语音合成电路接收所述 ECU发出的语音提示指令， 利用预先录制固化的语音合成， 发出语音报警 提示。
本发明的实施例中的气压采样数据中的预警数据（ >30%P, P为轮胎 正常气压值）发送频率设置为 l/60Hz， 控制数据 ( <30%P)的发送频率 设置为极小间隔或连续发送， 持续 10秒。
本发明系统控制程序流程图如图 3所示，系统启动后先执行自检程序， 确定系统工作状态正常后，进入接收数据分析处理程序。若数据传送异常， 系统进行远程监测模块异常轮位号识别， 并作出语音提示； 若传送正常则 执行下面的处理：
ECU接收到 30 %P (爆胎或快速泄气范围）气压采样数据时， 对汽车 实施行车干预控制措施，，包括制动减速和减小节气门开度， 同时实施语音 提示；
ECU接收到 > 30% P且 < 60% P气压（严重欠压范围）采样数据时， 实 施提示频率'为 1/60HZ的重度欠压语音提示；
ECU接收到 >60%PJL< 80% P气压 (欠压范围）采样数据时， 实施提 示频率为 1/600HZ的欠压语音提示；
ECU接收到 > 80%?且<120%？气压（气压正常范围）采样数据时， 实 施提示频率为 1/3600HZ的气压正常语音提示；
ECU接收到 > 120%P气压 （超压范围）采样数据时，实施提示频率为 1 /600Hz的超压语音提示。
以上具体实施方式仅用于说明本发明， 而非用于限定本发明。
