具体实施方式
为了能够更清楚地理解本公开的上述目的、特征和优点，下面将对本公开的方案进行进一步描述。需要说明的是，在不冲突的情况下，本公开的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本公开，但本公开还可以采用其他不同于在此描述的方式来实施；显然，说明书中的实施例只是本公开的一部分实施例，而不是全部的实施例。
基于相关技术存在的问题，本公开实施例提供一种轮胎磨损检测方法，包括：获取车辆运行状态下的工况信息，其中，工况信息至少包括车速信息和转速信息；根据车速信息和转速信息确定车辆的实际轮胎半径；根据实际轮胎半径与预设轮胎半径之间的关系，确定轮胎的磨损程度，其中，预设轮胎半径为车辆在初始运行工况下的轮胎半径，即通过获取车辆处于运行状态下的工况信息，基于工况信息的车速信息和转速信息确定车辆在运行状态下的实际轮胎半径，并根据实际轮胎半径与预设轮胎半径之间的关系，确定轮胎的磨损程度，实现在车辆行驶过程中，基于实时采集的车速信息和转速信息确定车辆的实际轮胎半径，并比较车辆行驶过程中的实际轮胎半径与预设轮胎半径之间的关系，确定轮胎的磨损程度，实现对轮胎进行实时检测，检测效率更为高效，此外，由于整个检测过程无需手动检测，因此检测结果也更为准确。
本公开实施例提供的轮胎磨损检测方法可应用于终端设备上，该终端设备可为专门用于对轮胎磨损情况进行检测的检测设备，也可以为现有车辆的终端设备来执行，其中，车辆的终端设备例如可以是车载主控模块。下面以几个具体的实施例对本公开的技术方案做详细描述。
图1为本公开提供的一种轮胎磨损检测方法的流程示意图，如图1所示，本实施例的方法包括：S10至S30。
S10、获取车辆运行状态下的工况信息。
在一些实施例中，工况信息至少包括车速信息和转速信息。
为了实现对轮胎的磨损情况进行高效检测，本实施例的轮胎磨损检测方法可直接基于 车辆的终端设备进行检测。当车辆处于运行状态下时，即车辆轮胎处于运动状态时，本实施例通过获取车辆运行状态下的工况信息，例如车速信息和转速信息。
具体的，可基于车载GPS(全球定位系统，Global Positioning System)获取车辆行驶时的车速信息，基于ESP(车身电子稳定系统，Electronic Stability Program)获取车辆行驶过程中车辆轮胎的转速信息。
需要说明的是，上述实施例示例性表示基于车载GPS获取车辆的车速信息以及基于ESP获取车辆轮胎的转速信息，在具体的实施方式中，不同车辆配置不同，因此获取车辆车速信息以及转速信息的具体模块本公开实施例不对此进行限定。
S20、根据车速信息和转速信息确定车辆的实际轮胎半径。
当车载GPS采集到车辆处于运动状态时的车速信息，ESP采集到车辆处于运动状态的转速信息后，车辆的终端设备获取车载GPS采集的车辆的车速信息以及ESP采集到的车辆的转速信息，并根据获取到的车速信息和转速信息确定车辆的处于运行状态下的实际轮胎半径。
需要说明的是，由于车辆轮胎在车辆处于运行状态下时会发生磨损现象，车辆轮胎磨损程度与车辆的运行距离有关，因此，当车辆运行距离较短，基于获取的车速信息和转速信息确定的车辆的实际轮胎半径与预设轮胎半径之间的差值较小，因此，作为一种具体的可实施方式，通过周期性检测车辆运行状态下的工况信息，例如，在车辆初始运行工况下获取车辆的初始车速信息和初始转速信息，在车辆运行距离大于或等于1000KM时，获取车辆运行距离大于或等于1000KM之后处于运行状态下的工况信息，此时基于车辆运行状态的工况信息确定的实际轮胎半径与预设轮胎半径之间的关系，确定轮胎的磨损程度。
为保证可以对轮胎的磨损程度进行实时检测，通过设定预设周期，例如，车辆行驶距离满足1000KM后获取依次车辆的车速信息和转速信息，即1000KM、2000KM、...、10000KM对应的行驶距离分别获取车辆的车速信息和转速信息，并基于车速信息和转速信息确定车辆的实际轮胎半径。
S30、根据实际轮胎半径与预设轮胎半径之间的关系，确定轮胎的磨损程度。
在一些实施例中，预设轮胎半径为车辆在初始运行工况下的轮胎半径。
具体的，当车辆处于初始运行工况时，车辆的轮胎未发生磨损，通过获取车辆在初始运行工况下的轮胎半径，可以确定车辆的预设轮胎半径。
在一种具体的实施方式中，可以获取车辆在初始运行工况下的初始车速信息和初始转速信息，基于初始车速信息和初始转速信息计算得到车辆的预设轮胎半径。
在另一种具体的实施方式中，基于车辆的TPMS(轮胎压力监测系统，Tire Pressure Monitoring System)监测车辆轮胎胎压，当车辆轮胎胎压处于正常胎压范围内时，此时基 于获取的车速信息和轮速信息计算得到车轮的预设轮胎半径。
本公开实施例通过比较实际轮胎半径与预设轮胎半径之间的关系，确定轮胎的磨损程度，由于实际轮胎半径基于获取车辆运行状态的工况信息确定的，因此，可以实现对轮胎进行实时检测，检测效率更为高效，此外，本申请实施例提供的轮胎磨损检测方法，整个检测过程无需手动检测，因此检测结果也更为准确。
本公开实施例提供的轮胎磨损检测方法，获取车辆运行状态下的工况信息，其中，工况信息至少包括车速信息和转速信息，根据车速信息和转速信息确定车辆的实际轮胎半径，根据实际轮胎半径与预设轮胎半径之间的关系，确定轮胎的磨损程度，其中，预设轮胎半径为车辆在初始运行工况下的轮胎半径，即通过获取车辆处于运行状态下的工况信息，基于工况信息的车速信息和转速信息确定车辆在运行状态下的实际轮胎半径，并根据实际轮胎半径与预设轮胎半径之间的关系，确定轮胎的磨损程度，实现在车辆行驶过程中，基于实时采集的车速信息和转速信息确定车辆的实际轮胎半径，并比较车辆行驶过程中的实际轮胎半径与预设轮胎半径之间的关系，确定轮胎的磨损程度，实现对轮胎进行实时检测，检测效率更为高效，此外，由于整个检测过程无需手动检测，因此检测结果也更为准确。
图2是本公开实施例提供的另一种轮胎磨损检测方法的流程示意图。本公开实施例是在上述实施例的基础上，如图2所示，步骤S20的一种具体可实现方式包括：S21和S22。
S21、根据转速信息和圆周信息确定角速度信息。
在一些实施例中，根据转速信息和圆周信息的乘积确定角速度信息。
在具体的实施方式中，当基于ESP获取车辆的转速信息后，基于角速度信息、圆周信息与转速信息之间的关系，可以获取车辆的角速度信息。
在一个实施例中，角速度信息与转速信息之间的关系表达式为：ω＝2πn，其中，ω为角速度信息，n为转速信息，2π为圆周信息。
需要说明的是，当转速信息的单位为rpm(转/分)，角速度信息的单位为w/s(弧度/秒)，则角速度信息与转速信息之间的另一种关系表达式为ω＝2πn/60。
S22、根据车速信息和角速度信息确定车辆的实际轮胎半径。
在一些实施例中，根据车速信息和角速度信息的商值确定车辆的实际轮胎半径。
在具体的实施方式中，当基于GPS获取车辆的车速信息后，基于角速度信息、车速信息与轮胎半径之间的关系，可以获取车辆的实际轮胎半径。
在一个实施例中，角速度信息、车速信息与轮胎半径之间的关系表达式为：v＝ωr，其中，ω为角速度信息，r为轮胎半径。
本公开实施例提供的轮胎磨损检测方法，首先根据转速信息和圆周信息确定角速度信 息，然后基于车速信息和角速度信息确定车辆的实际轮胎半径，保证确定的车辆的实际轮胎半径的准确性。
图3是本公开实施例提供的又一种轮胎磨损检测方法的流程示意图，本公开实施例是在上述实施例的基础上，如图3所示，步骤S20的另一种具体可实施方式包括：S23。
S23、响应于转角信息与预设转角信息的差值小于或等于第一差值且扭矩信息与预设扭矩信息的差值小于或等于第二差值，根据车速信息和转速信息确定车辆的实际轮胎半径。
在一些实施例中，预设转角信息为车辆处于直线行驶对应的转角信息，预设扭矩信息为车辆处于匀速行驶对应的扭矩信息。
在一些实施例中，工况信息还包括：转角信息和扭矩信息。
由上述实施例可知，车辆的实际轮胎半径基于车速信息和转速信息确定，即确定的车辆的实际轮胎半径与车速信息和转速信息有关，在不同的运行工况下，获取的车速信息和转速信息存在一定的误差，为保证基于车速信息和转速信息确定的车辆的实际轮胎半径的准确度更高，本公开实施例提供的轮胎磨损检测方法，获取车辆运行状态下的工况信息还包括转角信息和扭矩信息，其中，转角信息反映车辆的转向角度，扭矩信息反映车辆的运行状态。为保证基于车速信息和转速信息确定的车辆的实际轮胎半径的准确性，本公开实施例提供的轮胎磨损检测方法，响应于转角信息与预设转角信息的差值小于或等于第一差值且扭矩信息与预设扭矩信息小于或等于第二差值，根据车速信息和转速信息确定车辆的实际轮胎半径。
需要说明的是，上述实施例中，转角信息与预设转角信息的差值指的是车辆在运行状态下车辆行驶可偏离直线行驶的角度，其中，车辆转弯行驶包括向左转弯行驶或向右转弯行驶。扭矩信息与预设扭矩信息的差值指的是车辆在运行状态下车辆行驶固定距离的加速度可偏离匀速行驶的大小，其中，行驶固定距离的加速度包括加速和减速。
作为一种具体的可实施方式，通过周期性检测车辆运行状态下的工况信息，例如，在车辆初始运行工况下获取车辆的初始车速信息和初始转速信息，在车辆运行距离大于或等于1000KM时，获取车辆运行距离大于或等于1000KM之后处于运行状态下的工况信息，此时基于车辆运行状态的工况信息确定的实际轮胎半径与预设轮胎半径之间的关系，确定轮胎的磨损程度。由于车辆运行距离大于或等于1000KM之时车辆的转角信息与预设转角信息的差值不一定满足第一差值，和/或车辆的扭矩信息与预设扭矩信息的差值不一定满足第二差值，此时，为保证获取的车辆的实际轮胎半径的准确性，在车辆运行距离大于或等于1000KM后，在1000KM～2000KM之间选取车辆的转角信息与预设转角信息的差值满足第一差值且车辆的扭矩信息与预设扭矩信息的差值满足第二差值工况下车辆的车速信息和转速信息，以此类推，依次获取不同不同检测周期车辆的实际轮胎半径。
此外，若基于车辆初始运行状态的初始车速信息和初始转速信息确定车辆的预设轮胎半径，此时，选取的车辆运行工况为在转角信息与预设转角信息的差值小于或等于第一差值且扭矩信息与预设扭矩信息的差值小于或等于第二差值对应的初始运行工况，保证获取的预设轮胎半径的准确性。
图4是本公开实施例提供的又一种轮胎磨损检测方法的流程示意图。本公开实施例是在上述实施例的基础上，如图4所示，该方法还包括：S40。
S40、根据轮胎的磨损程度，发送预警信息。
为保证驾驶员可以即使获取轮胎的磨损程度进而避免非必要事故的发生，当根据实际轮胎半径与预设轮胎半径之间的关系确定轮胎的磨损程度后，发送预警信息，保证驾驶员能够及时发现车辆轮胎的磨损问题，提高驾驶安全性。
具体的，根据轮胎的磨损程度，发送预警信息，包括：
响应于存在至少两个轮胎为二级磨损，发送第一预警信息，第一预警信息用于提醒驾驶员进行轮胎换位；
响应于存在单个轮胎为二级磨损，发送第二预警信息，第二预警信息用于提醒驾驶员进行轮胎更换及车辆车况检查。
在具体的实施方式中，轮胎的磨损程度包括一级磨损和二级磨损，其中一级磨损的磨损率小于二级磨损的磨损率，一级磨损表示车辆车况较好，驾驶员可以根据自己行驶路径合理规划时间进行车辆车况的检查，二级磨损表示车辆轮胎磨损较为严重，容易出现交通事故，建立驾驶员镜框进行轮胎更换。
此外，响应于车辆的轮胎磨损为二级磨损，对应不同的轮胎出现二级磨损现象，发送的预警信息不同。
具体的，响应于存在单个轮胎为二级磨损，发送第一预警信息，以实现基于第二预警信息提醒驾驶员进行轮胎换位及车辆车况检查，其中，存在单个轮胎为二级磨损可能是因为车辆转弯频率较大，造成左侧车轮或右侧车轮磨损严重，也可能是车辆车况存在问题，为保证车辆左右两侧轮胎地面附着力一致，发送第二预警信息以提醒驾驶员进行轮胎更换并进行车辆车况检查。此外，另一种情况，响应于至少两个轮胎为二级磨损，例如单轴(前轴或后轴)轮胎磨损时，其中前轴轮胎磨损可能是由于车辆为前驱车，使得车辆前轴轮胎磨损较为严重，此时，响应于确定存在至少两个轮胎为二级磨损，发送第一预警信息以提醒驾驶员进行轮胎更换。
需要说明的是，上述实施例中示例性表示基于车速信息和转速信息确定车辆的实际轮胎半径，在具体的实施方式中，车辆包括的轮胎为多个，因此，而车辆的车速信息确定的，因此，当不同轮胎的磨损率不同，对应的轮胎的转速信息不同，因此基于车速信息和转速 信息确定的实际轮胎半径可以分别为不同轮胎对应的实际轮胎半径，在进行实际轮胎半径与预设轮胎半径比对时，依次比较不同轮胎对应的实际轮胎半径与预设轮胎半径之间的关系。
作为一种可实施方式，根据实际轮胎半径与预设轮胎半径之间的关系，确定轮胎的磨损程的具体实施方式包括：
响应于实际轮胎半径与预设轮胎半径的差值小于预设阈值，确定轮胎为一级磨损；
响应于实际轮胎半径与预设轮胎半径的差值大于或等于预设阈值，确定轮胎为二级磨损；
其中，二级磨损的磨损率大于一级磨损的磨损率，一级磨损表示轮胎正常，二级磨损表示所述轮胎异常。
通过比对实际轮胎半径与预设轮胎半径的差值与预设阈值之间的关系，确定轮胎的磨损程度，响应于实际轮胎半径与预设轮胎半径的差值小于预设阈值，确定轮胎为一级磨损，响应于实际轮胎半径与预设轮胎半径的差值大于或等于预设阈值，确定轮胎为二级磨损。
