[0080] 为了解决这一问题,本实施例中的胎压监测装置,不需要预先定义压力传感器对应的轮胎,当轮胎位置发生改变时,胎压监测装置自动调整所显示的轮胎位置。 [0080] In order to solve this problem, the position of the tire pressure monitoring device of the present embodiment in the embodiment, no need to define a pressure sensor corresponding to the tire, when the tire position is changed, the device automatically adjusts the tire pressure monitoring display.

[0081] 本实施例中的胎压监测装置包括安装于轮胎内部的压力传感器,压力传感器测量轮胎气压并将气压数据发送到接收器上;安装于驾驶室内的接收器及显示器,接收器接收压力传感器的气压数据,显示器将气压数据进行显示;安装于轮胎上、与压力传感器一一对应的轮速传感器,轮速传感器监测轮胎转动圈数,也即是监测轮胎行驶距离;安装在汽车方向盘上的转角传感器,转角传感器监测方向盘的转动角度。 [0081] The tire pressure monitoring device of the present embodiment comprises a pressure sensor mounted inside a tire embodiment, the pressure sensor measuring the tire pressure and the air pressure data transmitted to the receiver; attached to the cab and a display of the receiver, the receiver receives pressure pressure sensor data, the display will show the air pressure data; mounted on the tire, the pressure sensor correspondence wheel speed sensor, wheel speed sensors monitor the tire rotation number, that is, the running distance of the tire monitor; steering wheel mounted on a vehicle the rotation angle sensor, monitoring the rotational angle of the steering wheel angle sensor.

[0082] 在胎压监测过程中,当方向盘转角大于预设角度时,记下方向盘转动方向(左、右, 也可定义为+或-、〇或1等),通过轮速传感器记录四个轮胎转动圈数,乘以轮胎的周长即四个轮胎的行驶距离。 [0082] In the course of monitoring tire pressure, when the steering angle is greater than a preset angle, note the direction of rotation of the steering wheel (left, right, also be defined as + or -, or a square, etc.), recorded by the four wheel speed sensor rotation number of the tire, multiplied by the circumference of the tire, ie four tires travel distance. 通过对四个轮胎行驶距离的对比,结合方向盘的转动角度判断出四个轮胎所处位置,建立起压力传感器的气压数据与轮胎位置的对应关系,并将对应关系显示在显示器上。 By the angular distance of four tires with the comparison, it is determined that the steering wheel in conjunction with the location of the four tires, caused to correspond to the position relationship between the tire air pressure data of the pressure sensor, and the correspondence relationship displayed on the display.

[0083] 上述方案中,重点是通过对四个轮胎行驶距离的对比,结合方向盘的转动角度判断出四个轮胎所处位置。 [0083] In the above-described embodiment, by focusing on the angle of rotation of the tire with four comparison distance, the steering wheel is judged four binding tire location. 如图1所示,汽车右转时从位置A行进到位置B,图2所示为四个轮胎在右转过程中的行驶距离,可以看出四个轮胎的行驶距离都不相同;图3右下角所示的四条线的长度与四个轮胎的行驶距离分别相同,四条线由上至下分别为右后轮胎、右前轮胎、左后轮胎、左前轮胎的行驶距离,可以看出,右后轮胎的行驶距离〈右前轮胎的行驶距离〈左后轮胎的行驶距离〈左前轮胎的行驶距离。 As shown, a right turn when the car 1 travels from position A to position B, the Figure 2 shows the travel distance of four tires during a right turn, the four tires can be seen running distance is not the same; FIG. 3 four lines are the same as shown in the lower right corner of the length of the four tires of the running distance, respectively, from top to bottom four lines right rear tire, front right tire, rear left tire, front left tire travel distance, it can be seen right after the running distance of the tire <front right tire running distance <left rear tire running distance <traveling distance of the front left tire. 图4为汽车右转时左前轮胎和右前轮胎的行驶轨迹示意图;图5为汽车右转时左后轮胎和右后轮胎的行驶轨迹示意图;图6为汽车右转时右后轮胎的行驶轨迹示意图;图7为汽车右转时右前轮胎的行驶轨迹示意图;图8为汽车右转时左后轮胎的行驶轨迹示意图;图9为汽车右转时左前轮胎的行驶轨迹示意图。 FIG 4 is a schematic front left tire and the right front tire of the car traveling locus turning; FIG. 5 is a schematic rear left tire and the right rear tire of automobile is traveling locus right turn; FIG. 6 is a schematic view of the right rear tire track cars right turn ; FIG. 7 is a schematic diagram of the right front tire traveling locus when the vehicle turning; FIG. 8 is a schematic view of the left rear tire traveling locus when the vehicle is turning; FIG. 9 is a schematic view of the left front tire of the car traveling locus right.

[0084] 具体地,在某次转弯过程中,轮速传感器检测到: [0084] Specifically, in a certain time during the turning of the wheel speed sensor detects:

[0086]~则可以判定 [0086] - it can be determined

[0088] ^从而实现通过对四个轮胎行驶距离的对比,结合方向盘的转动角度判断出四个轮胎所处位置。 [0088] ^ four tires in order to achieve the travel distance by contrast, the rotation angle of the steering wheel is determined in conjunction with the location of the four tires.

[0089] 值得注意的是,当轮胎胎压不正常时不进行自动重设。 [0089] It is noted that when the tire pressure is not abnormal automatically reset. 原因是当某个(或多个)轮胎胎压不正常时(比如正常值设定为2.2bar-3. Obar,则此数值之外的为不正常气压),轮胎的半径与理论半径相差较大,轮胎滚动时行驶的距离与理论距离不相符。 The reason is that when one (or more) is not normal tire pressure (for example, set to normal 2.2bar-3. Obar, the value is not outside this normal atmospheric pressure), with the theoretical radius than the radius of the tire differ large, running the tire rolls distance and distance does not match the theory.

[0090] 另外汽车左转和右转时轮胎行驶状态相反,因此分别记录左转和右转时方向盘的转动角度。 [0090] Further when the vehicle traveling state of the tire opposite to left and right, respectively, thus recording the rotation angle of the left and right turn of the steering wheel. 再者,当轮胎打滑时,本实施例的胎压监测装置不工作。 Further, when the tire slip, tire pressure monitoring device of the present embodiment does not work.

[0091] 本实施例在汽车每个轮胎内部设置有压力传感器,压力传感器监测所在轮胎的气压并将获取的气压数据发送给中央处理模块,中央处理模块确定每个压力传感器所处轮胎的位置,建立气压数据与轮胎位置之间的对应关系,显示器显示所述对应关系。 [0091] The present embodiment is provided with a pressure sensor in the interior of each car tire, the tire pressure sensor monitors the pressure where the acquired pressure data to the central processing module, the processing module determines the central position of each of the tire pressure sensor is located, establishing a correspondence between the position of the tire air pressure data, the display shows the corresponding relationship. 通过本发明的技术方案,不需要定义各个传感器对应的轮胎位置,即使汽车的轮胎位置改变,也能保证监测数据的正确性。 By aspect of the present invention, no tire define the position of each sensor corresponding to the location of the vehicle even if the tire is changed, can ensure the accuracy of the monitoring data.
