Description

一种调整限速值的方法、装置和车辆 技术领域
本申请实施例涉及智能驾驶领域，并且更具体地，涉及一种调整限速值的方法、装置和车辆。
背景技术
新能源汽车普遍存在续航焦虑问题，尤其是低电量或续航不足的场景下，因此提升续航里程非常关键。通过限制车速来节约能耗是非常有效的方式，原因是高车速时风阻大会导致车辆的能耗高，同时通过限制车速可以减少用户激烈驾驶的情况。当前车辆的限速值通常是固定不变的，这样会影响到车辆的安全性。
发明内容
本申请实施例提供一种调整限速值的方法、装置和车辆，有助于提升车辆的安全性，也有助于提升用户的体验。
本申请中的车辆(有时简称为车)为广义概念上的车辆，可以是交通工具(如汽车、卡车、摩托车、飞机、火车、轮船等)，工业车辆(如：叉车、挂车、牵引车等)，工程车辆(如挖掘机、推土车、吊车等)，农用设备(如割草机、收割机等)，游乐设备，玩具车辆等，本申请实施例对车辆的类型不作具体限定。

本申请实施例中，在加速踏板开度和/或加速踏板开度变化率满足预设条件时，车辆可以将限速值由第一限速值调高至第二限速值。这样，可以通过加速踏板开度和/或加速踏板开度变化率判断用户是否有紧急加速的意图。在识别到用户有紧急加速的意图时，通过提高限速值，有助于保证车辆在紧急情况(例如，需要进行超车时)下有提速的空间，有助于提升车辆的安全性，也有助于提升用户的驾乘体验。同时，通过动态调整限速值，可以满足车辆在不同场景下的需求，有助于提升车辆的智能化程度。

本申请实施例中，车辆可以获取第一目标行驶里程以及在第一剩余电量和第一限速值下的第一续航里程，若第一续航里程小于或者等于第一距离，则可以将车辆的限速值调整为第三限速值。这样，在续航里程不能支持车辆完成行驶任务时，通过降低限速值可以提升车辆的续航里程，有助于避免由于续航里程不足给用户带来的风险，从而有助于提升用户的驾乘体验。同时，通过动态调整限速值，有助于提升车辆的智能化程度。

如图2中的(b)所示，在检测到加速踏板的开度大于或者等于第一阈值(例如，80％)时，车辆可以认为用户有加速超车的意图，从而可以通过中控屏显示提示框206，其中，提示框206中包括提示信息“检测您正在加速超车，已为您将限速值提升至120km/h”。通过将限速值从90km/h提升至120km/h，可以使得用户驾驶车辆完成超车。
一个实施例中，在检测到加速踏板的开度大于或者等于第一阈值时，车辆可以在第四预设时长(例如，30秒)内将限速值提升。
例如，在检测到加速踏板的开度大于或者等于第一阈值(例如，80％)时，车辆可以启动定时器，该定时器的时长可以为30秒。在定时器运行期间，车辆的限速值调整至120km/h。在定时器超时后，车辆的限速值调整至90km/h。

例如，该第一模式可以为运动模式或者舒适模式。
S802，获取加速踏板开度和/或加速踏板开度变化率的信息。
示例性的，控制装置710可以通过加速踏板开度传感器采集的信息获取加速踏板开度和/或加速踏板开度变化率。
以上加速踏板的开率可以位于0～100％，0为未检测到用户踩踏加速踏板时的开度，100％为检测到用户将加速踏板踩到底时的开度。
以上加速踏板开度的变化率可以理解为单位时间内加速踏板开度的变化率。例如，在时长△T内加速踏板的开度由k 1增加至k 2，那么加速踏板开度的变化率可以由以下公式(1)确定：
Figure PCTCN2022102795-appb-000001
其中，Roc为加速踏板的开度变化率。
S803，判断加速踏板的开度是否大于或者等于阈值A。
示例性的，该阈值A可以为80％
若加速踏板的开度小于阈值A，则可以返回执行S802。
S804，在加速踏板的开度是否大于或者等于阈值A时，将车辆的限速值调整为限速值2，其中，限速值2大于限速值1。
在加速踏板的开度是否大于或者等于阈值A，控制装置710中的驾驶意图识别模块712可以识别到用户有紧急加速的意图，从而可以将车辆的限速值从限速值1调整至限速值2。
一个实施例中，在加速踏板的开度是否大于或者等于阈值A时，将车辆的限速值调整为限速值2，包括：在加速踏板的开度是否大于或者等于阈值A时，在预设时长内将车辆的限速值调整为限速值2。
一个实施例中，该方法还包括：在加速踏板的开度小于该阈值A时，将车辆的限速值调整为限速值1。
S805，判断加速踏板的开度变化率是否大于或者等于阈值B。

应理解，S803-S804和S805-S806可以是并行的。
示例性的，控制装置710可以以1秒为周期计算加速踏板的开度变化率。这样，当某个周期内的开度变化率大于或者等于阈值B时，可以将限速值调整至限速值3。
一个实施例中，限速值2和限速值3可以相同，或者，也可以不同。
一个实施例中，在加速踏板的开度变化率是否大于或者等于阈值B时，可以启动定时器，其中，在定时器运动期间可以将限速值调整至限速值3；在定时器超时时，可以将限速值调整至限速值1。

一个实施例中，在加速踏板的开度变化率小于阈值B的持续时长大于或者等于预设时长时，可以将车辆的限速值调整至限速值1。
一个实施例中，可以在预设时长内将车辆的速度从当前速度调整至限速值1。
示例性的，控制装置710可以以1秒为周期计算加速踏板的开度变化率。这样，当某个周期内的开度变化率大于或者等于阈值B时，可以启动定时器(例如，定时器的时长为10秒)。这样在接下来的10秒内可以不用判断加速踏板的开度变化率与阈值B的关系，且在这10秒内可以将限速值调整至限速值3。在10秒过后，可以继续判断加速踏板的开度变化率与阈值B的关系。若加速踏板的开度变化率小于阈值B，则将限速值调整至限速 值3；若加速踏板的开度变化率大于或者等于阈值B，则可以继续启动该定时器。
或者，在启动定时器的过程中可以继续判断加速踏板的开度变化率与阈值B的关系，例如在0-5秒时加速踏板的开度变化率小于阈值B，而在第6秒时检测到加速踏板的开度变化率再一次大于或者等于阈值B，那么定时器的时长可以从第6秒重新启动定时器。若定时器运行期间内加速踏板的开度变化率均小于阈值B，那么在定时器超时时可以将限速值调整至限速值3。
示例性的，限速值1为90km/h。当车辆的速度为80km/h且加速踏板的开度大于或者等于80％时，控制装置可以将车辆的限速值调整为110km/h，从而车辆的速度可以由80km/h提升至105km/h。在检测到加速踏板的开度小于80％时，控制装置可以将车辆的限速值从110km/h降低至90km/h。同时，控制装置可以在预设时长内将车辆的速度从105km/h降低至90km/h。
例如，控制装置可以控制车辆的速度在30秒或者1分钟内从105km/h降低至90km/h。
又例如，控制装置可以通过直线或者曲线变化，将车速从105km/h降低至90km/h。
又例如，控制装置可以通过查表的方式获取从当前的车速变化至限速值1所需要的时长，从而在该时长内将车速从当前车速降低至限速值1。
本申请实施例中，通过在预设时长内将车辆的限速值由当前车速调节为第一限速值，避免由于急减速给用户带来的影响，有助于提升限速值调节过程中用户的驾驶舒适性，从而有助于提升用户的驾乘体验。

例如，控制装置710可以基于车辆最近行驶的100km的估计来预测在剩余电量以及限速值1下的续航里程1。如可以将最近通过限速值1行驶的100km进行分段，分别计算[0，10km)、[10，20km)、[20，30km)、[30，40km)、[40，50km)、[50，60km)、[60，70km)、[70，80km)、[80，90km)、[90，100km]时的能耗值，并基于这些能耗值计算平均能耗值。控制装置710可以基于车辆最近通过限速值1行驶的100km的平均能耗值确定在剩余电量以及限速值1下的续航里程1。
又例如，控制装置710还可以计算最近通过限速值1行驶的100km的综合能耗值。在计算综合能耗值时，每一段的权重可以是不一样的。例如[0，50km)中每一段对应的能耗的权重值可以高于[50，100km]中每一段对应的能耗的权重值。控制装置710可以基于最近通过限速值1行驶的100km的综合能耗值确定在剩余电量以及限速值1下的续航里程1。
一个实施例中，控制装置710可以基于车辆之前在该路线上行驶时的历史能耗信息确定在剩余电量以及限速值1下的续航里程1。
例如，控制装置710可以根据车辆之前5次在该路线上行驶时的平均能耗值确定在剩 余电量以及限速值1下的续航里程1。
一个实施例中，控制装置710也可以基于模式1下的平均能耗来预测续航里程1。不同模式下的平均能耗可以由不同模式下的单位里程平均驱动能耗和附件功率相加得出。单位里程平均驱动能耗可基于整车控制器在不同模式下，在不同工况(也可以是标准综合工况)下的试验标定数据作为预设值读取。附件能耗可基于不同模式下所有工作附件的能耗(如空调、中控屏、音响、灯光、座椅等附件功率)总和计算。

目标行驶里程2的确定过程可以参考上述实施例中目标行驶里程1的确定过程，此处不再赘述。
S912，判断续航里程2是否大于第二距离。
例如，在t 1时刻，车辆确定在剩余电量10％以及90km/h的限速值下的续航里程1为45km。在续航里程1小于或者等于第一距离45km(例如，第一距离可以目标行驶里程45公里以及固定值5km的和)时，车辆可以将限速值调整至70km/h，其中，在剩余电量10％以及70km/h的限速值下的续航里程(例如，)大于该第一距离。

一个实施例中，若续航里程2小于或者等于该第二距离，则在判断限速值是否已经调整至最低限速值的同时还可以判断在该最低限速值下的续航里程是否大于该第二距离。例如，若限速值已经调整至最低限速值且在该最低限速值下的续航里程小于或者等于该第二距离，那么可以提示用户续航里程不足以达到目的地，或者，提示用户寻找充电桩。
S914，若未调整至最低限速值，则车辆可以继续将车辆的限速值调整为限速值7，其中，限速值7小于或者等于限速值6。
一个实施例中，在限速值7下的续航里程大于该第二距离。
这样，在车辆还未调整至最低限速值时，可以通过进一步降低限速值提升车辆的续航里程，有助于进一步降低由于续航里程不足带来的风险。
S915，若限速值已经调整至最低限速值，则提示用户续航里程不足以达到目的地，或者，提示用户寻找充电桩。
以上在确定目标行驶里程时可以结合导航信息或者地图信息来确定，本申请实施例并不限于此。在没有导航信息或者地图信息的情况下，也可以根据历史行驶记录确定目标行 驶里程。
例如，当车辆上电后可以通过定位系统获取当前车辆所处的位置(例如，车辆当前位于xx大厦)。车辆可以根据车辆中保存的小计里程的信息确定车辆从xx大厦出发时可能要行驶的目标行驶里程。
又例如，在一个月内，车辆从起始位置为xx大厦出发了20次，其中，目的地为家的次数为13次，目的地为餐厅A的次数为5次，目的地为学校A的次数为2次。此时，车辆可以预测本次行驶的目的地可能为家，从而车辆可以根据车辆保存的地图信息或者车辆可以小计里程的信息获取从xx大厦至家的目标行驶里程(例如，目标行驶里程为40km)。
又例如，车辆可以在历史行驶记录中保存从xx大厦行驶至每个目的地的次数，或者，车辆也可以在历史行驶里程中保存每次从xx大厦出发时的行驶里程。例如，在一个月内，车辆从起始位置为xx大厦出发了20次，且行驶里程为38km-40km的次数为15次，行驶里程为8km-10km的次数为3次，行驶里程为60km-70km的次数为2次。此时，车辆可以预测用户的目标行驶里程为40km。
一个实施例中，该历史行驶记录中还可以保存有预设时间段内车辆从某个位置出发时的行驶记录。例如，表1示出了车辆在一个月内的历史行驶记录。

应理解，以上表1所记录的数据仅仅是示意性的，历史行驶记录中可以包括比上述表格中更多或者更少的数据，本申请实施例并不限于此。
例如，当车辆上电时的位置为xx大厦且上电时的时刻为下午6点，那么车辆可以根据上述表1所示的历史行驶记录预测该目标行驶里程为30km，或者，该目标行驶里程为下午5点下午7点期间20次行驶里程的平均值(例如，该平均值29km)。
一个实施例中，该历史行驶记录中还可以保存有预设时间段内车辆从某个位置出发时的行驶记录。表2示出了车辆在一个月内的另一历史行驶记录。

应理解，以上表2所记录的数据仅仅是示意性的，历史行驶记录中可以包括比上述表格中更多或者更少的数据，本申请实施例并不限于此。
例如，当车辆上电时的位置为xx大厦且上电时的时刻为周五下午6点，那么车辆可以根据上述表2所示的历史行驶记录预测该目标行驶里程为65km，或者，该目标行驶里程为下午5点下午7点期间4次行驶里程的平均值(例如，该平均值63km)。
一个实施例中，历史行驶记录中还可以包括用户的身份信息。
例如，表3示出了车辆在一个月内的另一历史行驶记录。
表3历史行驶记录
Figure PCTCN2022102795-appb-000005
例如，当车辆上电时，可以通过座舱内的摄像装置(例如，驾驶员监测系统(driver monitor system，DMS)的摄像头或者座舱监测系统(cabin monitor system，CMS)的摄像头)采集主驾区域的图像信息并通过该图像信息确定用户的身份信息，例如，主驾区域的用户为用户B。若车辆当前的位置为xx小区且上电时的时刻为上午8点，那么车辆可以根据上述表3所示的历史行驶记录预测该目标行驶里程为45km，或者，该目标行驶里程为上午7点至上午9点期间10次行驶里程的平均值(例如，该平均值43km)。
本申请实施例中，当车辆无法获取导航信息时，还可以结合预设时间段内车辆从该某个位置出发时的一个或者多个行驶里程确定第一距离，这样，可以使得车辆得到更为准确的第一距离的信息，有助于进一步降低由于续航里程不足带来的风险，从而有助于提升用户的驾乘体验。
图10示出了本申请实施例提供的调整限速值的方法1000的示意性流程图。如图10所示，该方法1000包括：
S1001，确定车辆进入第一模式，在第一模式下车辆的限速值为限速值1。
以上S1001可以参考S801的描述，此处不再赘述。
S1002，根据道路的拥堵程度和/或道路的限速值，将车辆的限速值调整为限速值8。
一个实施例中，若车辆所在的道路的限速值为60km/h且该道路的限速值低于限速值1，那么车辆可以将限速值调整至限速值8，其中限速值8小于该道路的限速值。
一个实施例中，根据道路的拥堵程度和/或道路的限速值，将车辆的限速值调整为限速值8，包括：在道路通畅且限速值1小于该道路的限速值时，可以将车辆的限速值调整为限速值8，其中，限速值8大于限速值1。
示例性的，该道路的限速值可以为100km/h，限速值8可以为100km/h。
示例性的，该道路的限速值可以为120km/h，限速值8可以为110km/h。
一个实施例中，根据道路的拥堵程度和/或道路的限速值，将车辆的限速值调整为限速值8，包括：在检测到该车辆位于第一类型的道路时，根据该道路的拥堵程度和/或该道路的限速值，将该车辆的限速值调整为限速值8；其中，该第一类型的道路包括高速公路、市区道路或者市郊道路。
示例性的，当检测到车辆位于高速公路时，若道路通畅且限速值1小于该高速公路的限速值时，可以将车辆的限速值调整为限速值8。而在检测到车辆位于市郊道路时，若道路通畅且限速值1小于该市郊道路的限速值时，可以将车辆的限速值保持在限速值1。
一个实施例中，车辆可以根据导航信息或者地图信息确定车辆所处的道路的类型。
一个实施例中，车辆也可以根据传感器(例如，车外的环视摄像头)采集的图像确定车辆所处的道路的类型。
一个实施例中，根据道路的拥堵程度和/或道路的限速值，将车辆的限速值调整为限速值9，包括：在该道路拥堵时，将该车辆的限速值调整为该限速值9，该限速值9小于该限速值1。
一个实施例中，可以基于导航信息和/或历史行驶记录确定道路的拥堵程度。
例如，当导航信息显示车辆前方10公里拥堵时，可以在距离拥堵路段1公里的地方将车辆的限速值调整至限速值9。这样，可以避免车辆在距离拥堵路段很近的地方急减速所造成的功耗浪费，有助于提升车辆的续航里程。
又例如，当车辆行驶的路线位于市区时，车辆可以结合历史行驶记录中保存的在该路线上的平均车速信息，确定是否将限速值1调整至限速值9。例如，车辆之前5次在该路线上行驶时的平均车速为30km/h，则可以认为车辆在该路线上行驶时会发生拥堵，则可以将该限速值调整为限速值9。
一个实施例中，可以根据该历史平均车速，确定该限速值9。
例如，若车辆在历史平均车速为30km/h-50km/h的路线上行驶时，该限速值9可以为60km/h。
又例如，若车辆在历史平均车速为50km/h-60km/h的路线上行驶时，该限速值9可以为70km/h。
一个实施例中，可以根据该道路的拥堵程度，确定该限速值9。
例如，导航信息显示前方路段严重拥堵时，该限速值9可以为50km/h。
又例如，导航信息显示前方路段一般拥堵时，该限速值9可以为70km/h。
本申请实施例中，在判断出道路拥堵时，可以通过降低限速值，避免用户由于急加速或者急减速所带来的能耗浪费，有助提升车辆的续航里程，避免由于续航里程不足带来的风险，有助于提升用户的驾乘体验。
以上图8至图10所示的各个实施例之间是可以相互结合的。
例如，在检测到续航里程1小于或者等于第一距离时，可以将限速值由90km/h降低至70km/h。在仅通过70km/h的限速值行驶的过程中，如果检测到加速踏板的开度大于阈值A，那么可以将限速值由70km/h提升至120km/h。在检测到加速踏板的开度小于该阈值A时，可以将该限速值由120km/h降低至70km/h。这样，在续航里程不足且检测到用户有紧急加速的意图时，通过安全优先的原则，可以提升限速值，保证车辆的提速空间，有助于提升车辆在紧急情况下的安全性。
又例如，车辆在高速公路上行驶时若检测到前方10公里发生拥堵，那么可以在距离拥堵路段1公里的地方将车辆的限速值由90km/h调整至70km/h。在仅通过70km/h的限速值行驶的过程中，如果检测到加速踏板的开度变化率大于阈值B，那么可以在20秒内将限速值由70km/h提升至120km/h。20秒后可以将该限速值由120km/h降低至70km/h。这样，在续航里程不足且检测到用户有紧急加速的意图时，通过安全优先的原则，可以提升限速值，保证车辆的提速空间，有助于提升车辆在紧急情况下的安全性。
图11示出了本申请实施例提供的调整限速值的方法1100的示意性流程图。如图11所示，该方法1100包括：
S1101，获取运行在第一模式下的车辆的加速踏板开度和/或加速踏板开度变化率，在该第一模式下该车辆的限速值为第一限速值。
以上S1101可以参考上述图8中实施例的描述，此处不再赘述。
示例性的，第一限速值为90km/h。
S1102，在检测到该加速踏板开度和/或该加速踏板开度变化率满足预设条件时，将该车辆的限速值调整为第二限速值；其中，该第二限速值大于该第一限速值。
本申请实施例中，该预设条件可以包括预设时长内加速踏板的开度大于P％的次数与触发次数n的对应关系。例如，表4示出了预设时长内加速踏板的开度大于P％的次数、触发次数n、是否调整限速值的对应关系。

Figure PCTCN2022102795-appb-000006
如表4所示，在预设时长为T 1的时间段内，驾驶员实际踩加速踏板的开度大于P％的次数大于或者等于n，此时可以将限速值调整为第二限速值。预设时长为T 2的时间段内，驾驶员实际踩加速踏板的开度大于P％的次数大于2.5n，此时可以将限速值调整为第二限速值。预设时长为T 3的时间段内，驾驶员实际踩加速踏板的开度大于P％的次数大于5n，此时可以将限速值调整为第二限速值。
例如，还可以根据预设时长内加速踏板的开度大于P％的次数确定调整后的限速值。表5示出了60秒内加速踏板的开度大于70％的次数以及第二限速值的对应关系。
