Description

一种车辆制动控制方法、装置及存储介质
本申请要求于2020年08月05日提交中国专利局、申请号为202010779229.5，发明名称“一种车辆制动控制方法、装置及存储介质”的中国发明专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请 中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请实施例提供的车辆制动控制方法，可应用在如图1所示的车辆控制系统中，所述车辆控制系统包括行车制动系统101、倒车辅助系统102、左电子驻车制动系统103、右电子驻车制动系统104和车辆控制装置105，其中，行车制动系统101、倒车辅助系统102、左电子驻车制动系统103、右电子驻车制动系统104通过总线与车辆控制装置105进行通信。车辆控制装置通过确定车辆是否处于预设泊车状态，若车辆处于预设泊车状态，则实时监控车辆系统的状态信号，车辆系统包括行车制动系统、倒车辅助系统和电子驻车制动系统，进而根据行车制动系统、电子驻车制动系统和倒车辅助系统的状态信号确定车辆是否符合预设故障条件，若确定车辆符合预设故障条件，则拉起未发生故障的电子驻车制动系统，以控制车辆进行驻车。
本申请中，图1以车辆制动系统组合为一个行车制动系统、双电子驻车制动系统(EPB)为例进行说明，提供一种可应用于单行车制动系统、双驻车制动系统的车辆控制方案，以保证车辆的安全。其中，行车制动系统可以是车身电子稳定系统(ESP)，也可以是线控制动系统(onebox)。
车辆控制装置可以是一种无人车辆的低速行车与驻车冗余的协调控制软件模块，简称RCD软件模块(Redundant coordination Design)，是基于行车系统冗余设计与驻车系统冗余设计来进行开发的，本实施例中，以车辆控制装置为RCD软件模块为例进行说明。
在一实施例中，如图2所示，提供一种车辆制动控制方法，以该方法应用在车辆控制系统中的车辆控制装置为例进行说明，包括如下步骤：
S10：确定车辆是否处于预设泊车状态。
本实施例中的车辆制动控制方法可应用于低速自动驾驶的车辆控制场景中，包括低速无人代客泊车、遥控泊车等预设的遥控泊车工况，因此，需要先确定车辆是否处于预设泊车状态，其中，可以通过车辆中车辆系统的信号来确定车辆是否处于预设泊车状态。
在一实施例中，确定车辆是否处于预设泊车状态需要判断：
确定车辆的倒车辅助系统是否握手成功。
根据车辆中倒车辅助系统的状态信号可获知倒车辅助系统是否握手成功。
实时获取车辆的车速，确定车辆的车速是否小于预设车速。
确定车辆所处环境的坡度，并确定车辆所处环境的坡度是否小于预设坡度。
其中，车辆所处环境的坡度通过加速度传感器来测算。
若车辆的倒车辅助系统握手成功，且车辆的车速小于预设车速，且车辆所处环境的坡度小于预设坡度，则确定车辆处于预设泊车状态。
若车辆的倒车辅助系统未握手成功，或者车辆的车速不小于预设车速，或者车辆所处环境的坡度不小于预设坡度，则确定车辆不处于预设泊车状态。
例如，在用户需要泊车时，若车辆的倒车辅助系统握手成功，且车辆的车速小于10km/h，且车辆所处环境的坡度小于10％，则确定车辆处于预设泊车状态，若车辆的倒车辅助系统未握手成功，或者车辆的车速不小于10km/h，或者车辆所处环境的坡度不小于10％，则确定车辆不处于预设泊车状态。将车辆制动控制方法的应用场景控制在10km/h以内车速和10％以内坡度的场景范围内，保证了车辆在低速遥控泊车工况中运行的安全性，并在倒车辅助系统未握手成功之后进行遥控泊车的相关控制，减少了车辆控制装置对车辆的一些其他不必要的信息采集和处理，减少车辆负担。
本实施例中，预设车速为10km/h、预设坡度为10％仅为示例性说明，在其他实施例中，预设车速还可以是其他车速，预设坡度还可以是其他坡度，在此不再赘述。
S20：若车辆处于预设泊车状态，则实时监控车辆系统的状态信号，车辆系统的状态信号包括行车制动系统、倒车辅助系统和多个电子驻车制动系统。
在确定车辆是否处于预设泊车状态之后，若车辆处于预设泊车状态，表示无人在车辆上，可能会出现因无人控制车辆导致的安全隐患，此时，需要实时监控车辆系统的状态信号，以确保能及时获知各车辆系统的工作状态，避免未及时获知各车辆系统的工作状态而未能对车辆进行及时控制，导致车辆出现安全事故的可能。其中，车辆系统包括行车制动系统、倒车辅助系统和多个电子驻车制动系统，车辆系统的状态信号包括行车制动系统的状态信号、倒车辅助系统的状态信号和多个电子驻车制动系统的状态信号。
S30：根据行车制动系统、电子驻车制动系统和倒车辅助系统的状态信号确定车辆是否符合预设故障条件。
在实时监控车辆系统的状态信号之后，根据行车制动系统的状态信号、电子驻车制动系统的状态信号和倒车辅助系统的状态信号确定车辆是否符合预设故障条件，即根据行车制动系统的状态信号、电子驻车制动系统的状态信号和倒车辅助系统的状态信号确定车辆系统是否出现故障情况，其中，本实施例中的故障情况包括系统失效和系统功能性损失。
S40：若确定车辆符合预设故障条件，则拉起未发生故障的电子驻车制动系统，以控制车辆进行驻车。
在根据行车制动系统的状态信号、电子驻车制动系统的状态信号和倒车辅助系统的状 态信号确定车辆是否符合预设故障条件之后，若确定车辆符合预设故障条件，则向未发生故障的电子驻车制动系统发送请求，使得未发生故障的电子驻车制动系统根据拉起请求立即拉起，以控制车辆进行驻车，从而保证车辆的安全。即在行车制动系统、倒车辅助系统和多个电子驻车制动系统中，只要有车辆系统出现故障情况，都需要考虑中断泊车动作，停止车辆并进行原地驻车。
此外，在车辆处于预设泊车状态时，不进行整车控制器(VCU)的监控和状态信号获取，RCD软件模块会向VCU发送驱动扭矩为0的请求，以避免出现意外而导致扭矩输出的情况，例如，防止倒车辅助系统(RPA)没有发送驱动扭矩为0的请求，导致VCU输出扭矩，从而导致安全事故，进而保证车辆的安全性。
本实施例中，针对单行车制动系统和双驻车制动系统的车辆设计了简单的控制方案，在车辆处于预设泊车状态时，通过实时监控行车制动系统、倒车辅助系统和电子驻车制动系统的状态信号来对车辆进行控制，即在根据各系统状态信号确定车辆发生系统故障时，直接拉起正常的电子驻车制动系统，以使车辆进行原地驻车，保证了车辆在低速遥控泊车时的安全性，解决了在配置单行车制动系统和双驻车制动系统的车辆中，没有匹配的控制方案来控制车辆完成遥控泊车，从而导致安全隐患的问题。
在一实施例中，步骤S30之后，即根据行车制动系统、电子驻车制动系统和倒车辅助系统的状态信号确定车辆是否符合预设故障条件之后，所述方法还具体包括如下步骤：
S301：若确定车辆不符合预设故障条件，则确定车辆的实时车速是否大于预设车速。
在根据行车制动系统、电子驻车制动系统和倒车辅助系统的状态信号确定车辆是否符合预设故障条件之后，若确定车辆不符合预设故障条件，表示车制动系统、电子驻车制动系统和倒车辅助系统的工作状态均正常，不需要进行系统故障工况下的保护性驻车，此时则需要确定车辆的实时车速是否大于预设车速，以根据车速确定是否需要进行超速防错措施。
S302：若车辆的实时车速大于预设车速，则拉起电子驻车制动系统，以控制车辆进行驻车。
在确定车辆不符合预设故障条件的情况下，确定车辆的实时车速是否大于预设车速之后，若车辆的实时车速大于预设车速，表示出现意外情况导致车速超出预设泊车状态下的车速限制，可能存在安全隐患，此时需要拉起电子驻车制动系统，以控制车辆进行驻车，从而避免安全事故的发生，提高车辆的安全性。
本实施例中，在根据行车制动系统、电子驻车制动系统和倒车辅助系统的状态信号确 定车辆是否符合预设故障条件之后，若确定车辆不符合预设故障条件，则确定车辆的实时车速是否大于预设车速，若车辆的实时车速大于预设车速，则拉起电子驻车制动系统，以控制车辆进行驻车，从而避免安全事故的发生，进而保证车辆安全。
在一实施例中，如图3所示，步骤S30中，即根据行车制动系统、电子驻车制动系统和倒车辅助系统的状态信号确定车辆是否符合预设故障条件，具体包括如下步骤：
S31：根据多个电子驻车制动系统的状态信号确定所有的电子驻车制动系统是否发生故障。
在获取多个电子驻车制动系统的状态信号之后，根据多个电子驻车制动系统的状态信号确定所有的电子驻车制动系统是否发生故障，以根据确定情况进行不同的车辆控制。
S32：若确定所有的电子驻车制动系统未发生故障，则根据倒车辅助系统的状态信号确定倒车辅助系统是否发生故障。
若确定所有的电子驻车制动系统未发生故障，表示车辆上所有的电子驻车制动系统正常工作，则进一步根据倒车辅助系统的状态信号确定倒车辅助系统是否发生故障。
例如，双电子驻车制动系统空可以为设置在车辆左侧的左电子驻车制动系统和设置在车辆右侧的右电子驻车制动系统，根据左电子驻车制动系统的状态信号确定左电子驻车制动系统是否发生故障，根据右电子驻车制动系统的状态信号确定右电子驻车制动系统是否发生故障，若左电子驻车制动系统和右电子驻车制动系统都未发生故障，则需进一步根据倒车辅助系统的状态信号确定倒车辅助系统是否发生故障。
S33：若确定倒车辅助系统发生故障，则根据行车制动系统的状态信号确定行车制动系统是否进行制动控制。
在确定所有的电子驻车制动系统未发生故障，并根据倒车辅助系统的状态信号确定倒车辅助系统是否发生故障之后，若确定倒车辅助系统发生故障，表示车辆容易出现安全性问题，需要立即停止车辆，则根据行车制动系统的状态信号确定行车制动系统是否进行制动控制。
S34：若确定行车制动系统未进行制动控制，则确定车辆符合预设故障条件。
在确定倒车辅助系统发生故障，则根据行车制动系统的状态信号确定行车制动系统是否进行制动控制之后，若确定行车制动系统未进行制动控制，表示行车制动系统可能出现问题，为保证车辆的安全需要控制车辆进行驻车，则确定车辆符合预设故障条件。
例如，当确定所有的电子驻车制动系统EPB未发生故障时，若倒车辅助系统的状态信号为invalid，表示倒车辅助系统失效，则确定倒车辅助系统发生故障，需要监控行车制 动系统ESP的状态信号，发现行车制动系统的主缸液压在预设时长(如500ms)内未有压力值，说明行车制动系统ESP未进行控制制动的动作，确定行车制动系统未进行制动控制，此时确定车辆符合预设故障条件，需要拉起未发生故障的电子驻车制动系统EPB，以控制车辆进行驻车，保证车辆的安全。
本实施例中，倒车辅助系统的状态信号为invalid，则确定倒车辅助系统发生故障仅为示例性说明，在其他实施例中，确定倒车辅助系统发生故障的方式还可以是其他，在此不再赘述。
本实施例中，行车制动系统的主缸液压在预设时长内未有压力值则确定行车制动系统未进行制动控制仅为示例性说明，预设时长为500ms仅为示例性说明，在其他实施例中，确定行车制动系统未进行制动控制的方式还可以是其他，预设时长还可以是其他时长，在此不再赘述。
本实施例中，通过根据多个电子驻车制动系统的状态信号确定所有的电子驻车制动系统是否发生故障，若确定所有的电子驻车制动系统未发生故障，则根据倒车辅助系统的状态信号确定倒车辅助系统是否发生故障，若确定倒车辅助系统发生故障，则根据行车制动系统的状态信号确定行车制动系统是否进行制动控制，若确定行车制动系统未进行制动控制，则确定车辆符合预设故障条件，细化了根据行车制动系统、电子驻车制动系统和倒车辅助系统的状态信号确定车辆是否符合预设故障条件的步骤，明确了判断预设故障条件的逻辑，后续控制车辆进行驻车提供了依据。
在一实施例中，在确定所有的电子驻车制动系统未发生故障之后，所述方法还具体包括如下步骤：
S36：根据行车制动系统的状态信号确定行车制动系统是否发生故障。
在确定所有的电子驻车制动系统未发生故障之后，还可以根据行车制动系统的状态信号直接确定行车制动系统是否发生故障，以根据行车制动系统的具体工作状态确定是否符合预设故障条件。
S37：若行车制动系统发生故障，则确定车辆符合预设故障条件。
在根据行车制动系统的状态信号确定行车制动系统是否发生故障之后，若行车制动系统发生故障，则确定车辆符合预设故障条件，直接拉起电子驻车制动系统，使得所有的电子驻车制动系统进行配合以控制车辆进行驻车。
本实施例中，在确定所有的电子驻车制动系统未发生故障之后，通过根据行车制动系统的状态信号确定行车制动系统是否发生故障，若行车制动系统发生故障，则确定车辆符 合预设故障条件，在电子驻车制动系统未发生故障的情况下，进一步根据行车制动系统的状态信号判断是否符合预设故障条件，增加了满足预设故障条件的工况，从而增加了拉起电子驻车制动系统进行驻车的工况，进而提高了车辆的安全性。
在一实施例中，步骤S31之后，即根据电子驻车制动系统的状态信号确定电子驻车制动系统是否发生故障之后，所述方法还具体包括如下步骤：
S311：若确定其中一个电子驻车制动系统发生故障，且另一电子驻车制动系统未发生故障，则向行车制动系统发送减速停车请求。
在根据电子驻车制动系统的状态信号确定电子驻车制动系统是否发生故障之后，若确定其中一个电子驻车制动系统发生故障，且另一电子驻车制动系统未发生故障，则向行车制动系统发送减速停车请求，以使行车制动系统根据减速停车请求配合未发生故障的电子驻车制动系统进行减速，退出泊车，以保证车辆的安全。
S312：确定行车制动系统是否执行减速停车请求。
在向行车制动系统发送减速停车请求之后，确定行车制动系统是否执行减速停车请求，以根据执行情况确定是否需要驻车。
S313：若行车制动系统未执行减速停车请求，则确定车辆符合预设故障条件。
在确定行车制动系统是否执行减速停车请求之后，若行车制动系统未执行减速停车请求，则确定车辆符合预设故障条件，以便未故障的电子驻车制动系统立即拉起。
本实施例中，通过在根据电子驻车制动系统的状态信号确定电子驻车制动系统是否发生故障之后，根据各电子驻车制动系统的具体故障情况进一步判断是否符合预设故障条件，若确定一电子驻车制动系统发生故障，且另一电子驻车制动系统未发生故障，则向行车制动系统发送减速停车请求，再确定行车制动系统是否执行减速停车请求，若行车制动系统未执行减速停车请求，则确定车辆符合预设故障条件，进一步增加了满足预设故障条件的工况，从而增加了拉起电子驻车制动系统进行驻车的工况，进而提高了车辆的安全性。
在一实施例中，如图4所示，所述车辆系统的状态信号还包括总线的状态信号，步骤S20之后，即实时监控车辆系统的状态信号之后，所述方法还具体包括如下步骤：
S21：根据总线的状态信号确定总线是否失效。
车辆系统的状态信号还包括总线的状态信号，在确定车辆处于预设泊车状态，实时监控车辆系统的状态信号之后，根据车辆系统的状态信号中总线的状态信号确定总线是否失效，以根据总线的状态确定是否需要驻车。
S22：若确定总线失效，则确定车辆符合预设故障条件。
在根据总线的状态信号确定总线是否失效之后，若确定总线失效，表示无法监控和获取包括行车制动系统、电子驻车制动系统和倒车辅助系统在内的车辆系统的状态信号，无法确定行车制动系统、电子驻车制动系统和倒车辅助系统的工作状态，为保证车辆的安全，此时确定车辆符合预设故障条件，以便拉起未故障的电子驻车系统，减少安全隐患。
本实施例中，在确定车辆处于预设泊车状态，实时监控车辆系统的状态信号之后，通过根据总线的状态信号确定总线是否失效，以根据总线的状态确定是否需要驻车，若确定总线失效，则确定车辆符合预设故障条件，减少了因总线失效无法确定行车制动系统、电子驻车制动系统和倒车辅助系统的工作状态导致的安全隐患，进一步增加了满足预设故障条件的工况，从而增加了拉起电子驻车制动系统进行驻车的工况，进而提高了车辆的安全性。
在一实施例中，步骤S40中，若确定车辆符合预设故障条件，在拉起未发生故障的电子驻车制动系统之前，所述方法还具体包括如下步骤：
S41：获取车辆所处的环境信息，环境信息包括道路信息、车辆与行驶方向上最近的障碍物之间的障碍物距离。
若确定车辆符合预设故障条件，在拉起未发生故障的电子驻车制动系统之前，还需要对车速进行安全验证，以保证拉起未发生故障的电子驻车制动系统的车速符合安全制动需求。因此需要在拉起未发生故障的电子驻车制动系统之前，获取车辆所处的环境信息，进而根据车辆所处的环境信息确定此时制动需要的安全车速，其中，环境信息包括道路信息、车辆与行驶方向上最近的障碍物之间的障碍物距离，道路信息包括坡度、路面光滑度等信息。
S42：根据道路信息和障碍物距离确定车辆驻车的初始车速。
在获取道路信息和障碍物距离之后，根据道路信息和障碍物距离查询预设安全数据，以确定车辆进行驻车的初始车速。
其中，预设安全数据为不同道路信息和障碍物距离下，车辆进行安全驻车的初始车速，包括不同的道路信息、障碍物距离和初始车速。
例如，将预设安全数据制定为初始车速map，并内置在车辆中，在获取道路信息和障碍物距离之后，根据道路信息和障碍物距离查询查询车辆内置的初始车速map，以获得车辆驻车的初始车速。
本实施例中，将预设安全数据制定为初始车速map并内置在车辆中仅为示例性说明，在其他实施例中，还可以将预设安全数据制定为其他数据形式，在此不再赘述。
在一实施例中，预设安全数据通过车辆安全性驻车试验获取。即在不同路面光滑度和坡度的道路上、不同障碍物距离的工况下对车辆进行安全驻车试验，以获得在车辆安全性驻车试验中，车辆在不同路面光滑度和坡度的道路上、不同障碍物距离的工况下进行驻车的安全的初始车速，并汇总作为预设安全数据。
本实施例中，预设安全数据通过车辆安全性驻车试验获取仅为示例性说明，在其他实施例中，预设安全数据还可以通过其他方式获取，在此不再赘述。
S43：确定拉起未发生故障的电子驻车制动系统前的车速是否大于初始车速。
获取拉起未发生故障的电子驻车制动系统前的车速，并在获取拉起未发生故障的电子驻车制动系统前的车速，且确定车辆驻车的初始车速之后，确定拉起未发生故障的电子驻车制动系统前的车速是否大于初始车速，以根据确定情况判断是否需要调整车速。
S44：若拉起未发生故障的电子驻车制动系统前的车速大于初始车速，则控制车辆以初始车速进行驻车。
在确定拉起未发生故障的电子驻车制动系统前的车速是否大于初始车速之后，若拉起未发生故障的电子驻车制动系统前的车速大于初始车速，表示此时的车速过大，以此时的车速进行驻车，在驻车过程中可能会与最近的障碍物发生碰撞，需要降低车速以使车辆安全驻车，则控制车辆以初始车速进行驻车，以保证车辆安全。
在确定拉起未发生故障的电子驻车制动系统前的车速是否大于初始车速之后，若拉起未发生故障的电子驻车制动系统前的车速不大于初始车速，表示此时的车速为安全驻车车速，以此时的车速进行驻车，在驻车过程中与最近的障碍物发生碰撞的可能性较小，可直接以拉起未发生故障的电子驻车制动系统前的车速进行驻车。
本实施例中，若确定车辆符合预设故障条件，在拉起未发生故障的电子驻车制动系统之前，通过获取车辆所处的环境信息，环境信息包括道路信息、车辆与行驶方向上最近的障碍物之间的障碍物距离，根据道路信息和障碍物距离确定车辆驻车时的初始车速，确定拉起未发生故障的电子驻车制动系统前的车速是否大于初始车速，若车辆驻车前的车速大于初始车速，则控制车辆以初始车速进行驻车，减少了驻车过程中与最近的障碍物发生碰撞的可能，进一步保证了车辆的安全。
在一实施例中，步骤S40之后，即控制车辆进行驻车之后，所述方法还具体包括如下步骤：
S51：确定是否接收到驾驶员或者整车控制器的驻车释放指令。
在控制车辆进行驻车之后，确定是否接收到驾驶员或者整车控制器的驻车释放指令， 进而根据接收情况确定是否经驻车释放，以避免车辆在预设泊车状态且车辆系统故障时，释放电子驻车制动系统所导致的安全事故。
例如，当接收到制动踏板踩下信，或者检测到车辆从下电状态进入上电状态且接收到电子驻车制动系统开关按下信号，或者接收到制动踏板换档信号(踩制动踏板以从P挡换到D挡或者R挡)时，确定是否接收到驾驶员的驻车释放指令；接收到整车控制器从P挡换到D挡或者R挡的换挡指令时，则确定接收到整车控制器的驻车释放指令。
本实施例中，通过上述方式确定是否接收到驾驶员或者整车控制器的驻车释放指令仅为示例性说明，在其他实施例中，还可以通过其他方式确定是否接收到驾驶员或者整车控制器的驻车释放指令，在此不再赘述。
S52：若接收到驾驶员或者整车控制器的驻车释放指令，则确定倒车辅助系统是否对车辆进行控制。
在确定是否接收到驾驶员或者整车控制器的驻车释放指令之后，若接收到驾驶员或者整车控制器的驻车释放指令，表示车辆已经由人进行控制，此时无需行车制动冗余或者驻车制动冗余，则进一步确定倒车辅助系统是否对车辆进行控制。
其中，通过根据倒车辅助系统的状态信号确定倒车辅助系统是否对车辆进行控制。例如，当倒车辅助系统退出泊车状态，或者倒车辅助系统的握手信号无效，或者倒车辅助系统的状态信号为invalid时，确定倒车辅助系统未对车辆进行控制。
S53：若确定倒车辅助系统未对车辆进行控制，则控制电子驻车制动系统执行驻车释放指令。
在确定倒车辅助系统是否对车辆进行控制之后，若确定倒车辅助系统未对车辆进行控制，此时车辆已经由人进行控制，车辆安全性得到保障，则控制电子驻车制动系统执行驻车释放指令。
本实施例中，在控制车辆进行驻车之后，通过确定是否接收到驾驶员或者整车控制器的驻车释放指令，以根据确定情况决定是否进行驻车释放，若接收到驾驶员或者整车控制器的驻车释放指令，则确定倒车辅助系统是否对车辆进行控制，若确定倒车辅助系统未对车辆进行控制，则控制电子驻车制动系统执行驻车释放指令，在接收驾驶员或者整车控制器的驻车释放指令、且不处于预设泊车状态之后进行驻车释放，减少了车辆在预设泊车状态且车辆系统故障时，释放电子驻车制动系统所导致的安全事故，进一步提高了车辆的安全性。
