进一步地,内部功能控制系统包括多个子系统,内部功能控制系统的多个子系统包括使用者信息系统,使用者信息系统用于获取目标对象的身份信息、车辆的目标对象的个数信息、驾驶员的驾驶状态信息,整车控制系统通过内部功能控制系统可调用身份信息、个数信息和驾驶状态信息。本实施例中,使用者信息系统可以提供有关用户、驾驶员身份ID、车内乘客人数、驾驶员状态信息(昏昏欲睡、分心……)、驾驶员是否在环等信息。
进一步地,内部功能控制系统包括多个子系统,内部功能控制系统的多个子系统还包括传感器融合系统,传感器融合系统用于将原始信息进行融合以获得融合信息,其中,原始信息包括如下至少之一:不同种类传感器的原始信息、摄像头视频流、毫米波点云信息、激光雷达点云信息。实施例中传感器融合系统可以将各种类型传感器的原始信息进行融合,包括摄像头视频流,毫米波雷达点云信息,激光雷达点云信息等,最终输出融合后的环境感知信息。
如图2所示,整车控制系统包括多个子系统,整车控制系统的多个子系统包括高等级自动驾驶控制系统、辅助驾驶控制系统,其中,高等级自动驾驶控制系统基于目标信息控制车辆的L3级以上自动驾驶目标策略,辅助驾驶控制系统基于目标信息控制车辆的L2级以下自动驾驶目标策略,L3级以上自动驾驶目标策略和L2级以下自动驾驶目标策略中的至少一个包括:控制车辆提供车辆的预设功能状态信息、在满足第一预设条件状态下控制车辆与驾驶员进行交互、基于目标对象的目的地信息规划路线并决策、控制车辆沿车辆的纵向和横向运动,以及控制车辆与周边物体保持安全距离。这样设置保证了车辆在自动行驶过程中的可靠性与安全性。
进一步地,整车控制系统的多个子系统还包括自动泊车控制系统,在自动泊车模式的情况下,自动泊车控制系统用于向整车控制系统提供车辆的状态信息,且在满足第二预设条件状态下控制车辆与驾驶员进行交互、基于目标对象的目的地信息规划路线并决策、控制车辆沿车辆的纵向和横向运动,以及控制车辆与周边物体保持安全距离。这样设置保证了车辆在自动泊车时的可靠性与安全性。
在本申请的另一实施例中,整车系统控制系统:对单个整车内的系统进行调度的功能服务,例如混动车辆燃油系统和电动系统切换的控制。整车系统控制管理层可以调用系统内部功能控制管理层、特定功能控制管理层,但是不能进行传感器、执行器控制管理层, 再一定程度上实现高层软件和底层传感器、执行器的解耦,不依赖于硬件资源变化,形成可适用的标准接口。
内部功能控制系统:对系统内部功能进行协调的功能服务,例如发动机系统的进排气、冷却的协调配合控制。内部功能控制管理层可以调用特定功能控制管理层,但不能直接调用传感器、执行器控制管理层更不能向更高等级的层级去调用。
特定功能控制系统:对特定功能进行控制的功能服务,例如发动机冷却系统的控制。特定功能控制管理层可以调用传感器、执行器控制管理层,该层涉及到直接的传感器数据读取以及执行器的控制。
信息采集系统:对整车所有传感器、执行器的控制和驱动抽离成服务,并形成一种动力能量域的分层软件架构,目的是通过软件分层以及软件模块的定义实现软件模块的职责以及各系统之间的高内聚,低耦合。软件层级之间的依赖关系,实现软件的可移植可复用,更加满足用户对整车功能新的需求,同时实现开发成本的减少,更加减少资源的投入。
如图1所示,整体原则为高层级软件模块可以调用低层级模块,但不可直接调用传感器、执行器层,低层级不可调用高层层级软件模块,整车系统控制管理层(整车控制系统)同层级软件模块可以相互调用以及接口使用,系统内部功能控制管理层(内部功能控制系统)、特定功能控制管理层(特定功能控制系统)同层级尽量避免去调用同层级的软件模块,传感器、执行器控制管理层(信息采集系统)则禁止去调用同层级的软件模块。此种分层方式将软件模块分为四层,在一定程度上实现了各系统之间的高内聚,低耦合,更加在整车层面实现资源的消耗,更使软件可以灵活部署并且可复用,减少软件模块之间的强依赖性,通过分层的概念将软件实现进一步的解耦。这样设置实现系统架构之间的分成管理,从而需要对该车辆进行增加和减少功能时,只需要对相应部分进行更改即可,无需对车辆整个架构进行更改,这样能够有效地降低车辆制造成本。
上述实施例中的车辆系统还可以应用于车辆技术领域,即根据本申请的另一个具体实施例,还提供了一种车辆,包括车辆系统,车辆系统为上述实施例中的车辆系统。
为了便于描述,在这里可以使用空间相对术语,如“在……之上”、“在……上方”、“在……上表面”、“上面的”等,用来描述如在图中所示的一个器件或特征与其他器件或特征的空间位置关系。应当理解的是,空间相对术语旨在包含除了器件在图中所描述的方位之外的在使用或操作中的不同方位。例如,如果附图中的器件被倒置,则描述为“在其他器件或构造上方”或“在其他器件或构造之上”的器件之后将被定位为“在其他器件或构造下方”或“在其他器件或构造之下”。因而,示例性术语“在……上方”可以包括“在……上方”和“在……下方”两种方位。该器件也可以其他不同方式定位(旋转90度或处于其他方位),并且对这里所使用的空间相对描述作出相应解释。
除上述以外,还需要说明的是在本说明书中所谈到的“一个实施例”、“另一个实施例”、“实施例”等,指的是结合该实施例描述的具体特征、结构或者特点包括在本申请概括性描述的至少一个实施例中。在说明书中多个地方出现同种表述不是一定指的是同一个实施例。 进一步来说,结合任一实施例描述一个具体特征、结构或者特点时,所要主张的是结合其他实施例来实现这种特征、结构或者特点也落在本申请的范围内。
在上述实施例中,对各个实施例的描述都各有侧重,某个实施例中没有详述的部分,可以参见其他实施例的相关描述。
以上所述仅为本申请的优选实施例而已,并不用于限制本申请,对于本领域的技术人员来说,本申请可以有各种更改和变化。凡在本申请的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本申请的保护范围之内。
