Description

气门、胎压调整方法及胎压调整装置
本申请要求在2021年07月14日提交中国专利局、申请号为202110793088.7、发明名称为“气门、胎压调整方法及胎压调整装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及汽车技术领域，尤其涉及气门、胎压调整方法及胎压调整装置。
背景技术
目前，大部分新出厂的车辆都配置有自动制动单元(autonomous emergency braking，AEB)。安装AEB的车辆可以采用雷达测出车辆与前车或者障碍物的距离，然后利用数据分析模块将测出的距离与安全距离进行比较，在测出的距离小于安全距离时即使在驾驶员没有来得及踩制动踏板的情况下，AEB系统也会启动，使汽车自动制动，从而为安全出行保驾护航。
然而现有AEB仅能在一部分场景中避免车辆与障碍物发生碰撞，在车辆与障碍物之间的距离过短，车速较快时，现有AEB无法避免车辆与障碍物发生碰撞。
发明内容
本申请提供了气门、胎压调整方法及胎压调整装置，能够降低车辆与物体发生碰撞的概率。为达到上述目的，本申请采用如下技术方案：
第一方面，本申请提供了一种气门，该气门包括：气嘴。所述气嘴内部设置有气门芯和定铁芯，所述气嘴外部的底部缠绕有线圈，所述定铁芯固定在所述气嘴内部的底部，所述线圈包括用于连接电源的接口。所述气门芯包括气门芯外壳、动铁芯和与所述动铁芯连接的弹簧，所述气门芯外壳顶部设置有气孔。所述线圈未通电时，所述弹簧对所述动动铁芯产生向上作用力，使得所述动铁芯与气门芯外壳底部相连。所述线圈通电时，所述气门芯外壳底部与所述动铁芯分离，所述气嘴内部的空气通过所述气门芯外壳底部进入气门芯并由所述气门芯外壳顶部的气孔排出。
本申请提供的气门，可以根据需要通电控制动铁芯与气门芯外壳底部分离，使车辆轮胎中的空气通过气门芯外壳底部进入气门并由气门芯外壳顶部的气孔排出，从而降低车辆轮胎的胎压，增大车辆轮胎与路面的摩擦系统，降低车辆的安全刹车距离，使降低后的车辆的安全刹车距离大于车辆与障碍物之间的距离，由此避免车辆与障碍物碰撞，降低车辆与物体发生碰撞的概率，提升了行车安全性。
在一种可能的实现方式中，所述线圈通电时，所述定铁芯产生磁场力吸引所述动铁芯与所述气门芯外壳底部分离，在不同供电电压下所述定铁芯的磁场力不同。
这样可以通过调整线圈的供电电压，使动铁芯与气门芯外壳底部分离程度发生改变，进而调整气门的排气速度。
在一种可能的实现方式中，所述气门还包括：胎压传感器。
这样可以通过气门中的胎压传感器，检测车辆轮胎的胎压，使用户可以获知车辆轮胎的胎压并在胎压异常(如胎压过低、胎压过高或胎压不平衡)时采取相应处理措施，进一步提升了行车安全性。
第二方面，本申请了一种胎压调整方法，该方法包括：首先获取第一距离，所述第一距离为车辆与目标物体之间的距离，所述目标物体为位于所述车辆行驶方向前方的物体。然后确定第二距离，所述第二距离为所述车辆的安全刹车距离。之后若所述第一距离小于所述第二距离，则根据所述第一距离和所述第二距离降低所述轮胎的胎压。
可以看出，本申请提供的胎压调整方法，可以在车辆与障碍物之间的距离小于车辆的安全刹车距离时，通过调整车辆轮胎的胎压，以增大车辆轮胎与路面的摩擦系统，从而降低车辆的安全刹车距离，使降低后的车辆的安全刹车距离大于车辆与障碍物之间的距离，由此避免车辆与障碍物碰撞，降低车辆与物体发生碰撞的概率，提升了行车安全性。
在一种可能的实现方式中，所述确定第二距离，包括：获取所述车辆的行驶速度和所述车辆的轮胎与地面之间的摩擦系数；根据所述行驶速度和所述摩擦系数确定所述第二距离。
可选地，所述第二距离L可以满足公式：L＝K(V*V)/(2μg)。其中，K为权重系数，V为车辆的行驶速度，μ为车辆的轮胎与地面之间的摩擦系数，g为重力常数。
示例性地，以获取的车辆行驶速度V为90千米/时即25米/秒，车辆的轮胎与地面之间的摩擦系数μ为0.7，权重系数K为0.8，重力系数g为9.8为例，则可以确定第二距离L＝0.8*(25*25)/(2*0.7*0.9)＝396.8米。
在一种可能的实现方式中，所述根据所述第一距离和所述第二距离降低所述轮胎的胎压，包括：根据所述第一距离和所述第二距离确定所述轮胎的胎压调整值；根据所述胎压调整值降低所述轮胎的胎压。
在一种可能的实现方式中，所述根据所述第一距离和所述第二距离确定所述轮胎的胎压调整值，包括：根据所述第一距离和所述第二距离确定第一差值，所述第一差值为所述第二距离与所述第一距离的差值；根据所述第一差值确定所述胎压调整值。
示例性地，以第一距离为100米，第二距离为101米，胎压每降低100千帕(Kpa)安全刹车距离降低2米为例，则可以根据第一距离和第二距离确定第一差值为101-100＝1米，确定胎压调整值为(1/2)*100＝50Kpa。
在一种可能的实现方式中，所述根据所述胎压调整值降低所述轮胎的胎压，包括：根据所述胎压调整值确定目标电压；根据所述目标电压调整所述轮胎的气门的供电电压，所述气门在通电后会将轮胎内部空气排出且在不同供电电压下所述气门的排气速度不同。
可以理解的是，不同的胎压调整值所需的排气速度不同，因此可以通过调整轮胎的气门的供电电压，为不同的胎压值调整调整合理的排气速度。例如，当胎压调整值较大时，分配较高的电压值，以使气门高速排气。反之，当胎压调整值较小时，分配较低的电压值，避免气门快速排气，以使气门低速排气，避免气门过度排气。
在一种可能的实现方式中，所述根据所述胎压调整值确定目标电压，包括：若所述胎压调整值大于第三阈值，则确定目标电压为第一电压；若所述胎压调整值小于或等于所述第三阈值，则确定目标电压为第二电压。其中，第一电压大于第二电压。
在一种可能的实现方式中，该方法还包括：若所述车辆的任一轮胎的胎压值小于第一阈值，则输出第一信息，所述第一信息用于指示所述车辆的轮胎的胎压值过低。
可以看出，本申请提供的胎压调整方法可以在车辆轮胎的胎压过低时，通过第一信息提醒用户车辆轮胎胎压过低，从而使用户可以及时为车辆轮胎补气以增加胎压，降低了因车辆胎压过低而发生行车事故的概率，进一步提升了行车安全性。
在一种可能的实现方式中，该方法还包括：若所述车辆的轮胎的胎压值均大于或等于所述第一阈值，则确定第二差值，所述第二差值为所述车辆的第一轮胎的胎压值与第二轮胎的胎压值的差值。
可以看出，本申请提供的胎压调整方法可以在车辆轮胎胎压不平衡时，调整车辆轮胎胎压，使车辆轮胎胎压平衡，从而降低因车辆胎压不平衡而发生行车事故的概率，进一步提升了行车安全性。
第三方面，本申请还提供一种胎压调整装置，该装置包括处理器，所述处理器用于：获取第一距离，所述第一距离为车辆与目标物体之间的距离，所述目标物体为位于所述车辆行驶方向前方的物体；确定第二距离，所述第二距离为所述车辆的安全刹车距离；若所述第一距离小于所述第二距离，则根据所述第一距离和所述第二距离降低所述轮胎的胎压。
在一种可能的实现方式中，所述处理器具体用于：获取所述车辆的行驶速度和所述车辆的轮胎与地面之间的摩擦系数；根据所述行驶速度和所述摩擦系数确定所述第二距离。
在一种可能的实现方式中，所述处理器具体用于：根据所述第一距离和所述第二距离确定所述轮胎的胎压调整值；根据所述胎压调整值降低所述轮胎的胎压。
在一种可能的实现方式中，所述处理器具体还用于：根据所述第一距离和所述第二距离确定第一差值，所述第一差值为所述第二距离与所述第一距离的差值；根据所述第一差值确定所述胎压调整值。

在一种可能的实现方式中，所述处理器还用于：若所述车辆的任一轮胎的胎压值小于第一阈值，则输出第一信息，所述第一信息用于指示所述车辆的轮胎的胎压值过低。
在一种可能的实现方式中，所述处理器还用于：若所述车辆的轮胎的胎压值均大于或等于所述第一阈值，则确定第二差值，所述第二差值为所述车辆的第一轮胎的胎压值与第二轮胎的胎压值的差值；若所述第二差值大于第二阈值，则降低所述第一轮胎的胎压。

目前，大部分新出厂的车辆都配置有AEB。安装AEB的车辆可以采用雷达测出车辆与前车或者障碍物的距离，然后利用数据分析模块将测出的距离与安全距离进行比较，在测出的距离小于安全距离时即使在驾驶员没有来得及踩制动踏板的情况下，AEB系统也会启动，使汽车自动制动，从而为安全出行保驾护航。
然而现有AEB仅能在一部分场景中避免车辆与障碍物发生碰撞，在车辆与障碍物之间的距离过短，车速较快时，现有AEB无法避免车辆与障碍物发生碰撞。例如，在图1所示的场景中，即使AEB在第一时间启动，使车辆自动制动，但由于车辆与目标物体之间的实际距离小于车辆的安全刹车距离，还是无法避免车辆与目标物体发生碰撞。
为此，本申请实施例提供了一种气门200，能够降低车辆与物体发生碰撞的概率。图2示出了该气门200的一种结构示意图，如图2所示，该气门200包括气嘴201。气嘴内部设置有气门芯202和定铁芯203，该定铁芯203固定在气嘴201内部的底部，气嘴201外部的底部缠绕有线圈204，线圈204包括用于连接电源的接口。气门芯202包括气门芯外壳205、动铁芯206和与动铁芯206相连的弹簧207，气门芯外壳205顶部设置有气孔208。线圈未通电时，弹簧207对动铁芯206产生向上作用力，使得动铁芯206与气门芯外壳205底部相连，动铁芯206挡住气门芯外壳205底部空气进入气门芯的入口；线圈通电时，气门芯外壳底部205与动铁芯206分离，气嘴201内部的空气通过气门芯外壳底部进入气门芯202并由气门芯外壳顶部的气孔208排出。
本申请实施例提供的气门200，可以根据需要通电控制动铁芯与气门芯外壳底部分离，使车辆轮胎中的空气通过气门芯外壳底部进入气门并由气门芯外壳顶部的气孔排出，从而降低车辆轮胎的胎压。
可选地，上述气门芯202可以通过螺纹固定在气嘴内部。
可选地，上述线圈204可以为铜线圈或其他材质的线圈(如铝线圈、银线圈等)。
在一种可能的实现方式中，上述线圈通电时，上述定铁芯产生磁场力吸引上述动铁芯向定铁芯方向移动，动铁芯移动过程中与上述气门芯外壳底部分离，并使得与上述动铁芯连接的弹簧产生形变。其中，在不同供电电压下上述定铁芯的磁场力不同，与上述动铁芯连接的弹簧的形变程度不同。
上述线圈断电时，上述定铁芯产生的磁场力消失，与上述动铁芯连接的弹簧复位并带动上述动铁芯向定铁芯反方向移动，动铁芯移动过程中与上述气门芯外壳底部相连。上述动铁芯与上述气门芯外壳底部相连后，车辆轮胎中的空气无法由上述气门芯外壳底部进入气门气门芯外壳顶部的气孔排出。
需要说明的是，本申请实施例提供的气门可以通过调整线圈的供电电压，使动铁芯与气门芯外壳底部分离程度发生改变，进而调整气门的排气速度。可以理解的是，不同的胎压调整值所需的排气速度不同，因此可以通过调整轮胎的气门的供电电压，为不同的胎压 值调整调整合理的排气速度。例如，当胎压调整值较大时，分配较高的电压值，以使气门高速排气。反之，当胎压调整值较小时，分配较低的电压值，避免气门快速排气，以使气门低速排气，避免气门过度排气。
本申请实施例提供的气门还可以包括胎压传感器。通过气门中的胎压传感器，检测车辆轮胎的胎压，使用户可以获知车辆轮胎的胎压并在胎压异常(如胎压过低、胎压过高或胎压不平衡)时采取相应处理措施，进一步提升了行车安全性。
本申请实施例还提供了一种胎压调整方法，能够降低车辆与物体发生碰撞的概率。该胎压调整方法可适用于本申请提供的胎压调整装置。该胎压调整装置可以为车辆300或集成在车辆300中。
图3是本申请实施例提供的车辆300的功能框图。如图3所示，该车辆包括胎压调整装置、传感器、制动单元、气门、轮胎和电源。
上述胎压调整装置用于执行本申请实施例提供的胎压调整方法。上述胎压调整装置可以为移动数据中心(mobile data center，MDC)、电子控制单元(electronic control unit，ECU)或其他设备，本申请实施例不做特别的限定。
上述传感器用于检测车辆的速度和车辆与其他物体之间的距离。上述传感器可以为雷达(例如激光雷达或毫米波雷达)或其他设备，本申请实施例不做特别的限定。
上述电源用于为车辆中的各设备(例如气门)供电。上述电源可以为蓄电池或其他设备，本申请实施例不做特别的限定。
上述车辆300可以为轿车、卡车、摩托车、公共汽车、挖掘机、洒水车、割草机、娱乐车、游乐场车辆、施工设备、电车、高尔夫球车等，本申请实施例不做特别的限定。
图4示出了本申请实施例提供的胎压调整方法的示意性流程图，该方法可以由本申请实施例提供的胎压调整装置执行。该方法包括：
S401、胎压调整装置获取第一距离。
其中，上述第一距离L1为车辆与目标物体之间的距离，上述目标物体为位于该车辆行驶方向前方的物体。例如，目标物体可以为图1中车辆行驶方向前方的障碍物。
示例性地，胎压调整装置可以通过车辆配置的视觉传感器，例如，摄像头等，或者距离传感器，例如，激光雷达，毫米波雷达或者超声波雷达等或其他设备获取上述第一距离。
S402、胎压调整装置确定第二距离。
其中，第二距离为该车辆的安全刹车距离。即该车辆的制动单元使该车辆停止所需的安全刹车距离。
在一种可能的实现方式中，胎压调整装置可以先获取该车辆的行驶速度和该车辆的轮胎与地面之间的摩擦系数。然后根据上述行驶速度和上述摩擦系数确定上述第二距离。
可选地，上述第二距离L可以满足公式：L＝K(V*V)/(2μg)。其中，K为权重系数，*为乘号，V为车辆的行驶速度，μ为车辆的轮胎与地面之间的摩擦系数，g为重力常数。
示例性地，以上述第二距离L可以满足上述公式：L＝K(V*V)/(2μg)，权重系数K为0.8，重力系数g为9.8为例。胎压调整装置获取的车辆的行驶速度V为90千米/时即25米/秒，则胎压调整装置以确定第二距离L＝0.8*(25*25)/(2*0.7*0.9)＝396.8米。
需要说明的是，在上述目标物体为非静止状态时，上述车辆的行驶速度可以是车辆与 目标物体之间的相对速度。例如，车辆的行驶方向为正北方，速度为30米/秒，目标物体的运动方向也为正北方，速度为15米/秒，由于车辆的行驶方向和目标物体的运动方向相同，则车辆的行驶速度为30-15＝15米/秒。又例如，车辆的行驶方向为正南方，速度为30米/秒，目标物体的运动方向为正北方，速度为15米/秒，由于车辆的行驶方向和目标物体的运动方向相反，则车辆的行驶速度为30+15＝15米/秒。
S403、胎压调整装置判断上述第一距离是否小于上述第二距离？若是，则执行S404；若否，则执行S405。
示例性地，以上述第一距离L1为100米，上述第二距离L为101米为例，由于上述第一距离(99米)小于上述第二距离(101米)，胎压调整装置则执行S404。
又示例性地，以上述第一距离L1为100米，上述第二距离L为95米为例，由于上述第一距离(100米)大于上述第二距离(95米)，胎压调整装置则执行S405。
需要说明的是，当上述第一距离小于上述第二距离，由于车辆与目标物体之间的距离(第一距离)小于车辆的安全刹车距离(第二距离)，这时即使车辆第一时间启动制动单元，也无法避免车辆与目标物体相撞，因此需要降低车辆的轮胎的胎压，使第二距离得以减小，减小后的第二距离小于第一距离，车辆在启动制动单元后，车辆可以在与障碍物相撞之前停止，从而避免车辆与目标物体相撞。
反之，当上述第一距离未小于上述第二距离，由于上述第二距离大于或等于上述第一距离，车辆启动制动单元后，车辆可以与障碍物相撞之前停止，所以车辆可以直接启动制动单元，而无需降低车辆的轮胎的胎压
在一种可能的实现方式中，胎压调整装置也可以根据上述第一距离和上述第二距离确定该车辆与上述目标物体相撞的概率H。然后车辆判断H是否大于零，若H大于零，则执行S404。
可选地，上述概率H可以满足公式：H＝(1-第一距离L1/第二距离L)*100％。例如，第一距离L1为90米，第二距离L为100米，则上述概率H＝(1-90/100)*100％＝10％。
S404、胎压调整装置启动制动单元并根据上述第一距离和上述第二距离降低车辆的轮胎的胎压。
在一种可能的实现方式中，上述根据上述第一距离和上述第二距离降低车辆的轮胎的胎压，包括：胎压调整装置先根据上述第一距离和上述第二距离确定上述轮胎的胎压调整值，然后根据上述胎压调整值降低上述轮胎的胎压。
在一种可能的实现方式中，上述根据上述第一距离和上述第二距离确定上述轮胎的胎压调整值，可以包括：胎压调整装置先根据上述第一距离和上述第二距离确定第一差值，该第一差值为上述第二距离与上述第一距离的差值，然后根据上述第一差值确定上述胎压调整值。
示例性地，以上述第一距离为100米，上述第二距离为101米，胎压每降低100千帕(Kpa)安全刹车距离降低2米为例，则胎压调整装置可以根据上述第一距离和上述第二距离确定上述第一差值为101-100＝1米，然后根据第一差值和胎压与安全刹车距离之间的对应关系，确定胎压调整值为(1/2)*100＝50Kpa。
在一种可能的实现方式中，上述根据上述胎压调整值降低上述轮胎的胎压，可以包括：胎压调整装置先根据上述胎压调整值确定目标电压，然后根据上述目标电压调整上述轮胎 的气门的供电电压。其中，上述气门在通电后会将轮胎内部空气排出且在不同供电电压下上述气门的排气速度不同。
可以理解的是，不同的胎压调整值所需的排气速度不同，因此可以通过调整轮胎的气门的供电电压，为不同的胎压值调整调整合理的排气速度。例如，当胎压调整值较大时，分配较高的电压值，以使气门高速排气。反之，当胎压调整值较小时，分配较低的电压值，避免气门快速排气，以使气门低速排气，避免气门过度排气。
在一种可能的实现方式中，上述根据上述胎压调整值确定目标电压，包括：若上述胎压调整值大于第三阈值，则确定目标电压为第一电压；若上述胎压调整值小于或等于上述第三阈值，则确定目标电压为第二电压。其中，第一电压大于第二电压。
在另一种可能的实现方式中，车辆也可以根据上述概率H确定上述目标电压，例如，当上述概率H大于第四阈值，则确定目标电压为第一电压；若上述概率H小于或等于上述第四阈值，则确定目标电压为第二电压。其中，第四阈值可以为50％。
可选地，上述气门可以为图2中本申请实施例提供的气门。
可选地，胎压调整装置还可以检测轮胎的胎压值是否降低至期望胎压值。若是，则停止向上述气门供电。若否，则继续向上述气门供电。其中，期望胎压值为胎压调整前车辆的轮胎的胎压值与胎压调整值的差。例如，胎压调整前车辆的轮胎的胎压值为290Kpa，胎压调整值为50Kpa，则期望胎压值为290-50＝240Kpa。车辆在轮胎的胎压值降低至240Kpa时，停止向气门供电。
如图5所示，在降低车辆的轮胎的胎压前，车辆与目标物体之间的距离(第一距离)小于车辆的安全刹车距离(第二距离)，如果这时不降低车辆的轮胎的胎压，即使车辆第一时间启动制动单元，也无法避免车辆与目标物体相撞。而在降低车辆的轮胎的胎压后，第二距离得以减小，减小后的第二距离小于第一距离，车辆在启动制动单元后，可以在与障碍物相撞之前停止，由此避免车辆与障碍物碰撞，降低车辆与物体发生碰撞的概率，提升了行车安全性。
S405、胎压调整装置启动制动单元。
可选地，胎压调整装置在启动制动单元时还可以：收紧安全带，以保护驾驶员及乘客；开启双闪灯，提醒后车注意保持安全车距。从而进一步提升行车安全性。
本申请另一实施例提供了一种胎压调整方法：
S406、胎压调整装置判断车辆的轮胎的胎压值是否均大于或等于第一阈值？若是，则执行S407；若否，则执行S410。
可选地，第一阈值可以为180Kpa。
需要说明的是，车辆的轮胎的胎压值大于或等于第一阈值说明车辆的轮胎的胎压正常。反之，车辆的轮胎的胎压值小于第一阈值，说明车辆的轮胎的胎压过低，这时车辆可以执行S410通过第一信息提醒用户车辆轮胎胎压过低，从而使用户可以及时为车辆轮胎补气以增加胎压，降低了因车辆胎压过低而发生行车事故的概率，进一步提升了行车安全性。
S407、胎压调整装置确定第二差值。
其中，上述第二差值为车辆的第一轮胎的胎压值与第二轮胎的胎压值的差值。
上述第一轮胎和上述第二轮胎为该车辆的任意两个轮胎。例如，第一轮胎可以为该车 辆的左前轮，第二轮胎可以为该车辆的右前轮。又例如，第一轮胎可以为该车辆的左前轮，第二轮胎可以为该车辆的左后轮。
S408、胎压调整装置判断上述第二差值是否大于第二阈值？若是，则执行S409。
其中，第二阈值可以为10Kpa。
需要说明的是，若第二差值大于第二阈值说明第一轮胎和第二轮胎的胎压不平衡，这时需要执行S409以降低第一轮胎使第一轮胎和第二轮胎的胎压平衡，从而降低因车辆胎压不平衡而发生行车事故的概率，进一步提升了行车安全性。
S409、胎压调整装置降低第一轮胎的胎压。
在一种可能的实现方式中，胎压调整装置可以根据第一轮胎的胎压值、第二轮胎的胎压值和第二阈值确定第一轮胎的胎压的调整值，然后根据第一轮胎的胎压的调整值降低第一轮胎的胎压。
示例性地，以第一轮胎的胎压值为270Kpa、第二轮胎的胎压值240Kpa、第二阈值为10Kpa为例。车辆确定第一轮胎的胎压的调整值为270-240-10＝20Kpa，然后根据第一轮胎的胎压的调整值确定目标电压，然后根据上述目标电压调整上述轮胎的气门的供电电压。
S410、胎压调整装置输出第一信息。
其中，第一信息用于指示该车辆的轮胎的胎压值过低。
示例性地，胎压调整装置可以通过在车载电脑的屏幕上显示第一信息以提示用户该车辆的轮胎的胎压值过低。
示例性地，胎压调整装置也可以通过扬声器播放第一信息以提示用户该车辆的轮胎的胎压值过低。
需要说明的是，本申请实施例提供的方法中S406至S410可以单独执行也可以和S401至S405组合执行，即胎压调整装置可以仅执行S406至S410而不执行S401至S405，在日常使用中，监控及调整胎压信息。胎压调整装置也可以先执行S401至S405后，再执行S406至S410，从而在紧急情况下调整胎压后继续监控胎压信息以提高行车安全性。S406至S410也可以先于S401至S405执行，即胎压调整装置可以先执行S406至S410，然后再执行S401至S405。
