具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
需要说明的是，本发明实施例及附图中的术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、***、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
本发明实施例公开了一种车辆行驶路线的推荐方法，能够自动为用户推荐包含充电桩的行驶路线，使得用户更容易找到充电桩。以下分别进行详细说明。
实施例一
请参阅图1，图1是本发明实施例公开的一种车辆行驶路线的推荐方法的流程示意图。其中，图1 所示的车辆行驶路线的推荐方法适用于车辆中控设备、车载电脑等车载电子设备，本发明实施例不做限定。如图1所示，该车辆行驶路线的推荐方法可以包括以下步骤：
101、推荐***根据用户的路线需求信息生成初始行驶路线。
在本发明实施例中，用户的路线需求信息可以包括行驶路线的起点、行驶目的地、经停点、路线偏好和充电需求等信息。其中，行驶路线的起点可以为车辆的导航***定位得出的车辆的当前位置，也可以由用户自行输入；路线偏好具体可以为高速优先、费用优先或者用时优先等选项；充电需求用于指示用户是否需要在行驶过程中对车辆进行充电。
可以理解的是，推荐***具体能够以车辆的当前位置为起点，以上述的行驶目的地为终点，生成经过上述经停点的初始行驶路线。如果以车辆的当前位置为起点，以上述的行驶目的地为终点，并且经过上述经停点的路线多于一条，推荐***可以根据用户输入的路线偏好从多条路线中选取出一条作为初始行驶路线。此外，推荐***在生成初始行驶路线之前，还可以先对行驶目的地进行校验。具体可以校验行驶目的地是否真实、是否唯一、行驶目的地距离车辆的当前位置是否超过预设的第一距离阈值(过远)、或者行驶目的地距离是否低于预设的第二距离阈值(过近)。如果行驶目的地真实、唯一、与车辆的当前距离低于第一距离阈值且高于第二距离阈值，行驶目的地的校验通过，生成到达该行驶目的地的初始行驶路线。
进一步地，推荐***在生成初始行驶路线之前，还可以进一步校验用户输入的经停点、路线偏好以及充电需求。具体可以校验经停点是否真实、是否唯一、途经该经停点需要绕行的路程是否超出第三距离阈值(绕路是否严重)；以及，校验用户输入的路线偏好需求是否明确，比如用户输入的路线偏好需求是否为高速优先、费用优先、用时优先等选项中的任一项，如果是，可以认为用户输入的路线偏好需求明确；以及，校验用户输入的充电需求是否合理，比如校验车辆的当前可续航里程可到达的范围内是否存在充电桩，如果是，可以认为用户输入的充电需求合理。
102、推荐***搜索在初始行驶路线沿途范围内的充电桩作为备选充电桩。
在本发明实施例中，初始行驶路线沿途范围为初始行驶路径上每个点的法线所构成的区域，并且每个点的法线长度相同。法线长度可以设置为相对较短的距离，比如可以设置为5公里，以方便车辆在较短的路程内到达充电桩。请一并参阅图2，图2是本发明实施例公开的一种初始行驶路线沿途范围内的充电桩分布示意图。如图2所示，以法线长度为5公里为例，当车辆行驶在初始行驶路线上时，沿途范围内的充电桩与车辆的距离均在5公里内。如图2所示，在沿途范围内的充电桩为符合范围的充电桩，可以将这些充电桩作为备选充电桩。在沿途范围之外的充电桩为不符合范围的充电桩，在执 行下述步骤203以生成推荐行驶路线时，不考虑这些不符合范围的充电桩。
作为一种可选的实施方式，如果在执行步骤101生成初始行驶路线时，接收到用户输入的经停点，在执行步骤102时，推荐***具体可以从初始行驶路线沿途范围内的充电桩中筛选出在位于车辆当前位置以及经停点之间的路段的充电桩作为备选充电桩。实施上述的实施方式，可以先考虑车辆从当前位置行驶至经停点时的电量补充，以减少备选充电桩的数量，从而减少生成推荐行驶路线时所需的计算量，提高推荐***的反馈速度。
103、推荐***以备选充电桩的位置作为经停点去调整初始行驶路线，以生成推荐行驶路线。
在本发明实施例中，作为一种可选的实施方式，推荐***执行步骤103的方式具体可以为：
当存在至少两个备选充电桩时，针对每一备选充电桩，推荐***通过调整初始行驶路线，生成途经该备选充电桩、与该备选充电桩对应的推荐行驶路线，以得到与备选充电桩的数量相同的推荐行驶路线。也就是说，针对每一备选充电桩都生成一条与之对应的推荐行驶路线。
可以理解的是，如果只有唯一的一个备选充电桩，相应地也只有一条与该备选充电桩相对应的推荐行驶路线。
请一并参阅图3-1及图3-2，图3-1是本发明实施例公开的一种初始行驶路线的示例图；图3-2是本发明实施例公开的一种推荐行驶路线的示例图。在图3-1及图3-2中，始发地A为车辆的当前位置，目的地B为车辆的行驶目的地，经停点C为用户输入的经停点。如图3-1所示，在初始行驶路线沿途范围内搜索出两个备选充电桩，假设针对每个备选充电桩均生成一个对应的推荐行驶路线，最终生成的两条推荐行驶路线如图3-2所示。
作为另一种可选的实施方式，推荐***执行步骤103的方式具体也可以为：
当存在至少两个备选充电桩时，从至少两个备选充电桩中筛选出每两个充电桩之间的间隔大于等于该车辆的建议行驶里程的充电桩，将上述的间隔大于等于建议行驶里程的充电桩作为同一条行驶路线上的不同经停点去调整初始行驶路线，以生成途经多个备选充电桩的推荐行驶路线。其中，上述的建议行驶里程可以为该车辆每两次充电之间平均可行使的里程。
104、推荐***输出推荐行驶路线。
在本发明实施例中，假设推荐***生成了至少两条推荐行驶路线，作为一种可选的实施方式，推荐***可以输出生成的所有推荐行驶路线。作为另一种可选的实施方式，推荐***也可以从至少两条推荐行驶路线中筛选出一条推荐行驶路线，并输出筛选出的推荐行驶路线。
可见，在图1所描述的方法中，推荐***在生成了初始行驶路线之后，可以搜索初始行驶路线附 近的备选充电桩，并且以备选充电桩作为经停点调整初始行驶路线，生成并输出途经备选充电桩的推荐行驶路线，使得用户可以更加容易地找到充电桩。此外，在生成推荐行驶路线的过程中，用户无需手动挑选合适的充电桩，更加方便快捷。
实施例二
请参阅图4，图4是本发明实施例公开的另一种车辆行驶路线的推荐方法的流程示意图。如图4所示，该车辆行驶路线的推荐方法可以包括以下步骤：
201、推荐***基于车辆的当前位置以及车辆的当前可续航里程，校验车辆可到达的范围内是否存在充电桩；如果是，执行步骤202；如果否，结束本流程。
在本发明实施例中，车辆的当前可续航里程指车辆在电量消耗至某一电量阈值之前，还可以继续行驶的里程。此外，车辆可到达的范围内的任一地点与车辆的当前位置之间的距离小于车辆的当前可续航里程。具体的，检验车辆可到达的范围内是否存在充电桩的具体方式可以为：搜索与车辆的当前位置距离最近的充电桩，并判断该最近的充电桩与车辆的当前位置之间的距离是否小于等于车辆的当前可续航里程；如果是，车辆可到达的范围内存在充电桩；如果否，车辆可到达的范围内不存在充电桩。
通过校验车辆可到达的范围内是否存在充电桩，校验用户输入的充电需求是否合理。当校验出车辆可到达的范围内不存在充电桩时，车辆开出后难以找到充电桩，车辆电量耗尽的风险较高，充电需求不合理。因此，结束本流程，不建议用户将车辆开出，从而可以降低由于难以充电导致车辆半路停止行驶的可能性。
202、推荐***根据用户的路线需求信息生成初始行驶路线。
203、推荐***搜索在初始行驶路线沿途范围内的充电桩。
204、推荐***基于车辆的当前位置以及车辆的当前可续航里程，从初始行驶路线沿途范围内的充电桩中筛选出车辆可到达的充电桩作为备选充电桩。
在本发明实施例中，当行驶目的地与车辆的当前位置之间的距离超过车辆开出时的可续航里程时，推荐***在初始行驶路线沿途范围内搜索到出的充电桩中可能存在部分充电桩是车辆无法到达的。因此，可以先筛选出这部分车辆无法到达的充电桩。请一并参阅图5，图5是本发明实施例公开的一种根据车辆的可续航里程筛选充电桩的示例图。如图5所示，续航半径所指示的圆弧内的区域为车辆可到达的范围。
通过对车辆可到达的充电桩进行筛选，可以降低距离车辆的当前位置较远的偏远充电桩对最终生成的推荐行驶路线的干扰，减少该路线绕路严重的可能性，提高推荐***选择充电桩的合理性。
205、推荐***以备选充电桩的位置作为经停点去调整初始行驶路线，以生成推荐行驶路线。
在本发明实施例中，作为一种可选的实施方式，推荐***执行步骤103的方式具体可以为：
当存在至少两个备选充电桩时，针对每一备选充电桩，推荐***通过调整初始行驶路线，生成途经该备选充电桩、与该备选充电桩对应的推荐行驶路线，以得到与备选充电桩的数量相同的推荐行驶路线。
206、推荐***输出推荐行驶路线中总行驶里程最短、总用时最短和/或总过路费用最少的路线。
在本发明实施例中，当执行步骤205生成至少两条推荐行驶路线时，从至少两条推荐行驶路线中优选出最佳路线，并输出最佳路线。其中，最佳路线可以为总行驶里程最短的推荐行驶路线、或者总用时最短的推荐行驶路线、或者总过路费最少的推荐行驶路线。可选的，可以只输出上述的三种最佳路线中的任意一条最佳路线，也可以输出任意两种最佳路线或者全部输出上述的三种最佳路线，本发明实施例不做限定。
请一并参阅图6，图6是图4所示的车辆行驶路线的推荐方法中部分步骤的实现示例图。图6所示为上述的步骤202～步骤206的实现示例。从图6中可以看出，推荐***最终能够为用户推荐一条从车辆的当前位置出发，最终到达行驶目的地，并且途经充电桩以及用户输入的经停点的车辆行驶路线。并且，推荐***能够确保车辆不会由于可续航里程的原因而无法到达充电桩，可以有效缓解用户的里程焦虑。
可见，在图4所描述的方法中，推荐***可以自动生成途经充电桩的行驶路线，以方便用户找到充电桩进行充电。进一步的，还可以在生成行驶路线之前校验车辆可到达的范围内是否存在充电桩，以减少剩余电量无法支持车辆行驶至充电桩的情况，降低由于难以充电导致车辆半路停止行驶的可能性。更进一步地，在搜索到初始行驶路线沿途范围内的充电桩之后，从中筛选出车辆可到达的充电桩作为备选充电桩，以降低偏远充电桩对最终生成的推荐行驶路线的干扰，减少该路线绕路严重的可能性，提高推荐***选择充电桩的合理性。此外，在图4所描述的方法中，推荐***可以从多条推荐行驶路线中优选出最佳行驶路线，从而为用户节省行车里程、行车时间或者过路费用。
实施例三
请参阅图7，图7是本发明实施例公开的另一种车辆行驶路线的推荐方法的流程示意图。如图7 所示，该车辆行驶路线的推荐方法可以包括以下步骤：
301、推荐***对请求参数进行校验，以判断请求参数是否存在异常；如果是，返回异常结果并结束本流程；如果否，执行步骤302。
在本发明实施例中，请求参数在用户发起导航请求时生成。对请求参数进行校验具体可以包括：1.校验行驶目的地是否真实、是否唯一、行驶目的地是否过远或者过远；2.校验用户输入的经停点是否真实、是否唯一、经停点绕路是否严重；3.校验用户输入的路线偏好需求是否明确；4.校验用户输入的路线偏好需求明确；5.校验车辆可到达的范围内是否存在充电桩。当上述的任一请求参数未通过校验，请求参数存在异常。
302、推荐***检索是否存在满足路线需求信息的初始行驶路线；如果是，执行步骤303；如果否，返回异常结果并结束本流程。
在本发明实施例中，满足路线需求信息的初始行驶路线指以车辆的当前位置为起点，以用户的行驶目的地为终点，并且经过用户输入的经停点的路线。303、推荐***检索在初始行驶路线沿途范围内是否存在充电桩；如果是，执行步骤304；如果否，返回异常结果并结束本流程。
304、推荐***搜索初始行驶路线沿途范围内的充电桩，以获得充电桩列表。
305、推荐***基于车辆的当前位置以及车辆的当前可续航里程，从充电桩列表中筛选出车辆可到达的充电桩作为备选充电桩。
在本发明实施例中，作为一种可选的实时方式，推荐***还可以针对充电桩列表中的每一充电桩，根据车辆曾经在该充电桩充电的历史次数、该充电桩当前的剩余空闲充电位个数、该充电桩的用户评价平均分以及该充电桩的充电单价对每一充电桩进行评估。针对某一充电桩，车辆在该充电桩充电的历史次数越高，该充电桩的评估分值越高；该充电桩的剩余空闲充电位个数越多，该充电桩的评估分值越高；该充电桩的用户评价平均分越高，该充电桩的评估分值越高；该充电桩的充电单价越低，该充电桩的评估分值越高。在综合以上的四个因素对充电桩进行评估之后，从充电桩列表中筛选出该车辆可到达并且评估分值高于某一分数阈值的充电桩作为备选充电桩。
306、推荐***针对每一个备选充电桩，加入备选充电桩作为经停点去调整初始行驶路线，以得到与每一备选充电桩相对应的推荐行驶路线。
307、推荐***从推荐行驶路线中筛选出最佳路线，并输出该最佳路线。
在本发明实施例中，最佳路线可以为总行驶里程最短、总用时最短、总过路费用最少的推荐行驶路线中的任意一条。可选的，如果用户输入了路线偏好需求，将与用户输入的路线偏好需求对应的推 荐行驶路线作为最佳路线。
此外，作为一种可选的实施方式，在本发明实施例中，当车辆按照推荐***输出的推荐行驶路线行驶时，如果检测到车辆利用备选充电桩完成充电，可以判断车辆的当前可续航里程是否小于车辆的当前位置与行驶目的地之间的距离；如果小于，根据车辆的当前位置以及车辆的当前可续航里程更新下一个备选充电桩；利用更新后的下一个备选充电桩对推荐行驶路线进行更新。
当车辆长途行驶时，只通过一次充电可能无法支持车辆到达行驶目的地。因此，需要考虑两次或以上的充电补给。实施上述的实施方式，可以在车辆完成一次充电之后，根据实时的车辆当前位置以及可续航里程对下一次充电时所用的备选充电桩进行更新，并进一步更新对应的推荐行驶路线。
可见，在图7所描述的方法中，推荐***可以自动为用户推荐途经充电桩的行驶路线，并且用户可以较为容易地到达推荐地充电桩，需要绕行的路程较短。进一步地，还可以在车辆完成一次充电之后，根据车辆的当前位置以及可续航里程对下一次充电时所用的备选充电桩进行更新，并进一步更新对应的推荐行驶路线，从而可以满足车辆在长途行驶时可能出现的两次或以上的充电需求。
实施例四

在本发明实施例中，用户的路线需求信息可以包括车辆的当前位置、用户输入的行驶目的地、经停点、路线偏好和充电需求等信息。

在本发明实施例中，作为一种可选的实时方式，搜索单元802可以从初始行驶路线沿途范围内的充电桩中筛选出在位于车辆当前位置以及经停点之间的路段的充电桩作为备选充电桩，以减少备选充电桩的数量，从而减少生成推荐行驶路线时所需的计算量，提高推荐***的反馈速度；
第二生成单元803，用于以备选充电桩的位置作为经停点去调整初始行驶路线，以生成推荐行驶路线；
在本发明实施例中，作为一种可选的实施方式，第二生成单元803可以在存在至少两个备选充电桩时，针对每一备选充电桩，通过调整初始行驶路线，生成途经该备选充电桩并且与该备选充电桩对应的推荐行驶路线，以得到与备选充电桩的数量相同的推荐行驶路线；
作为另一种可选的实施方式，第二生成单元803也可以在存在至少两个备选充电桩时，从至少两个备选充电桩中筛选出每两个充电桩之间的间隔大于等于该车辆的建议行驶里程的充电桩，将上述的间隔大于等于建议行驶里程的充电桩作为同一条行驶路线上的不同经停点去调整初始行驶路线，以生成途经多个备选充电桩的推荐行驶路线。其中，上述的建议行驶里程可以为该车辆每两次充电之间平均可行使的里程；
输出单元804，用于输出推荐行驶路线。
在本发明实施例中，输出单元804具体可以输出第二生成单元803生成的所有推荐行驶路线，也可以从至少两条推荐行驶路线中筛选出一条推荐行驶路线，并输出筛选出的推荐行驶路线，本发明实施例不做限定。
可见，实施如图8所示的车辆行驶路线的推荐***，可以在生成了初始行驶路线之后，搜索初始行驶路线附近的备选充电桩，并且以备选充电桩作为经停点调整初始行驶路线，生成并输出途经备选充电桩的推荐行驶路线，使得用户可以更加容易地找到充电桩。此外，在生成推荐行驶路线的过程中，用户无需手动挑选合适的充电桩，更加方便快捷。
实施例五
请参阅图9，图9是本发明实施例公开的另一种车辆行驶路线的推荐***的结构示意图。其中，图9所示的车辆行驶路线的推荐***是由图8所示的如图9所示的车辆行驶路线的推荐***进行优化得到的。如图9所示，上述的搜索单元802，具体可以包括：

筛选子单元8022，用于基于车辆的当前位置以及车辆的当前可续航里程，从初始行驶路线沿途范围内的充电桩中筛选出车辆可到达的充电桩作为备选充电桩。
通过对车辆可到达的充电桩进行筛选，可以降低距离车辆的当前位置较远的偏远充电桩对最终生成的推荐行驶路线的干扰，减少该路线绕路严重的可能性，提高推荐***选择充电桩的合理性。
在本发明实施例中，作为一种可选的实施方式，筛选子单元8022还可以针对初始行驶路线沿途范围内的每一充电桩，根据车辆曾经在该充电桩充电的历史次数、该充电桩当前的剩余空闲充电位个数、该充电桩的用户评价平均分以及该充电桩的充电单价对每一充电桩进行评估。其中，针对某一充电桩，车辆在该充电桩充电的历史次数越高，该充电桩的评估分值越高；该充电桩的剩余空闲充电位个数越多，该充电桩的评估分值越高；该充电桩的用户评价平均分越高，该充电桩的评估分值越高；该充电 桩的充电单价越低，该充电桩的评估分值越高。
相应地，筛选子单元8022用于基于车辆的当前位置以及车辆的当前可续航里程，从初始行驶路线沿途范围内的充电桩中筛选出车辆可到达的充电桩作为备选充电桩的方式具体可以为：
筛选子单元8022，用于基于车辆的当前位置、车辆的当前可续航里程、初始行驶路线沿途范围内的每一充电桩的评估分值，从初始行驶路线沿途范围内的充电桩中筛选出该车辆可到达并且评估分值高于某一分数阈值的充电桩作为备选充电桩。
可选的，图9所示的车辆行驶路线的推荐***中还可以包括：
校验单元805，用于在第一生成单元801根据用户的路线需求信息生成初始行驶路线之前，基于车辆的当前位置以及车辆的当前可续航里程，校验车辆可到达的范围内是否存在充电桩；如果存在，触发第一生成单元801执行根据用户的路线需求信息生成初始行驶路线的操作。
可选的，校验单元805也可以用于在第一生成单元801根据用户的路线需求信息生成初始行驶路线之前，校验路线需求信息中的行驶目的地是否真实、是否唯一、行驶目的地是否过远或者过远；以及，校验路线需求信息中用户输入的经停点是否真实、是否唯一、经停点绕路是否严重；以及，校验路线需求信息中用户输入的路线偏好需求是否明确；
通过在生成初始行驶路线之前对车辆可到达的范围内是否存在充电桩进行校验，可以降低由于难以充电导致车辆半路停止行驶的可能性。
进一步可选的，上述的第二生成单元803，具体可以用于在存在至少两个备选充电桩时，针对每一备选充电桩，通过调整初始行驶路线，生成途经备选充电桩并且与备选充电桩对应的推荐行驶路线，以得到与备选充电桩的数量相同的推荐行驶路线。
相应地，上述的输出单元804，具体用于输出推荐行驶路线中总行驶里程最短、总用时最短和/或总过路费用最短的路线，从而可以优选出最佳路线以供用户选择。
更进一步可选的，在图9所示的车辆行驶路线的推荐***中还可以包括：
判断单元806，用于在车辆按照推荐行驶路线行驶并且检测到车辆利用备选充电桩完成充电时，判断车辆的当前可续航里程是否小于车辆的当前位置与行驶目的地之间的距离；
上述的搜索单元802，还用于在判断单元判断出车辆的当前可续航里程小于车辆的当前位置与行驶目的地之间的距离时，搜索推荐行驶路线的沿途范围内的充电桩，以更新下一个备选充电桩；
上述的第二生成单元803，还用于利用更新后的下一个备选充电桩对推荐行驶路线进行更新。
在车辆利用备选充电桩完成一次充电之后，对备选充电桩以及推荐行驶路线进行更新，可以在车 辆完成一次充电之后，根据实时的车辆当前位置以及可续航里程对下一次充电时所用的备选充电桩进行更新，并进一步更新对应的推荐行驶路线，从而可以满足车辆在长途行驶时可能出现的两次或以上的充电需求。
其中，实施如图9所示的车辆行驶路线的推荐***，可以自动生成途经充电桩的行驶路线，以方便用户找到充电桩进行充电。进一步的，还可以在生成行驶路线之前校验车辆可到达的范围内是否存在充电桩，以减少剩余电量无法支持车辆行驶至充电桩的情况。更进一步地，从初始行驶路线沿途范围内的充电桩中筛选出车辆可到达的充电桩作为备选充电桩，以降低偏远充电桩对最终生成的推荐行驶路线的干扰，减少该路线绕路严重的可能性，提高推荐***选择充电桩的合理性。此外，还可以从多条推荐行驶路线中优选出最佳行驶路线，从而为用户节省行车里程、行车时间或者过路费用。以及，还可以在车辆完成一次充电之后，对下一次充电时所用的备选充电桩和对应的推荐行驶路线，从而可以满足车辆在长途行驶时可能出现的两次或以上的充电需求。
