下面参考附图描述本公开实施例的车辆的转向控制系统。
图1是根据本公开实施例的车辆的控制系统的方框示意图。如图1和图4所示,车辆的转向控制系统包括:方向盘10、方向盘转角传感器20、方向盘驱动单元30、转向机构40和控制模块50。
其中,方向盘10是驾驶员操作车辆行驶方向的装置,即言,方向盘10在驾驶员或乘客的操作下转动,具体地,当方向盘为一个时,方向盘可设置在驾驶员位置处,当方向盘为多个时,方向盘可设置在驾驶员位置处以及其他位置例如副驾驶员位置处。
方向盘转角传感器20可与方向盘10相连,具体地,方向盘10可通过转向管柱与方向盘转角传感器20进行连接,方向盘转角传感器20用于采集方向盘10的转动信息例如方向盘10的转动角度和转动速度。可以理解的是,方向盘转角传感器20可只采集方向盘10的转动角度而不采集方向盘10的转动速度,由此,在车轮根据方向盘10的转动角度转动时,通过实时跟随方向盘10的转动角度,即可使得车轮与方向盘的转动速度基本一致,即方向盘的转动速度快时,为跟随方向盘的角度,车轮的转动速度自然会相应的加快。
方向盘驱动单元30与方向盘10相连,方向盘驱动单元30用于驱动方向盘10转动以及向方向盘10施加转向力矩。也就是说,方向盘驱动单元30可在控制模块50的控制下驱动方向盘10转动,以保持方向盘与车轮的转动角度同步,并且,方向盘驱动单元30还可在方向盘10被驾驶员操作时向方向盘10施加转向力矩,从而给方向盘10提供反方向力矩,保证驾驶员手感舒适性。具体而言,当方向盘10在驾驶员的操作(转动)下顺时针转动时,方向盘驱动单元30给方向盘10施加逆时针方向的力矩,而当方向盘10在驾驶员的操作下逆时针转动时,方向盘驱动单元30给方向盘10施加时顺时针方向的力矩。
如图2-3以及图5-6所示,方向盘驱动单元30可包括方向盘驱动电机31,方向盘驱动电机31可通过转向管柱与方向盘10连接,方向盘驱动电机31可在控制模块50的控制下驱动方向盘10转动,或者向对应的方向盘10施加转向力矩,从而保证驾驶员手感舒适性。

控制模块50可与转向机构40例如转向电机42、方向盘驱动单元30和方向盘转角传感器20分别电连接。也就是说,控制模块50通过与方向盘转角传感器20电连接可接收方向盘转角传感器20采集的方向盘10的转动信息,控制模块50通过与转向机构40电连接以对转向机构40进行控制,控制模块50通过与方向盘驱动单元30电连接以对方向盘驱动单元30进行控制。
可以理解的是,在方向盘10被驾驶员操作而转动时,控制模块50可获取方向盘10的转动信息,并根据方向盘10的转动信息对转向机构40进行控制,还可对方向盘驱动单元30进行控制以使方向盘驱动单元30向方向盘10施加转向力矩。

可以理解的是,在根据方向盘10的转动信息对转向机构40进行控制过程中,控制模块50可获取车轮100的转动信息,并判断车轮100的转动信息与方向盘10的转动信息是否相一致即车轮100的转动角度与方向盘10的转动角度是否相一致,如果一致,则控制转向机构40停止驱动,如果不一致,则控制转向机构40继续驱动,直至车轮100的转动信息与方向盘10的转动信息相一致。
根据本公开的一个实施例,如图2以及图5-6所示,控制模块50可包括方向盘控制器51与转向控制器52,方向盘控制器51与方向盘驱动单元30和方向盘转角传感器20电连接,转向控制器52与转向机构40例如转向电机42、车轮转角传感器60电连接,方向盘控制器51与转向控制器52进行通信。具体地,转向控制器52可为EPS电子控制单元。

方向盘控制器51可以有线通信方式或无线通信方式与转向控制器52进行通信。更具 体地,有线通信方式可为CAN总线、MOST总线等,无线通信方式可为wifi、蓝牙等。
由此,方向盘与底层的转向器之间取消刚性连接,采用有线信号或无线信号代替机械结构来传递车辆驾驶员的转向意愿,例如方向盘控制器51可以通过CAN总线与转向控制器52进行连接,CAN总线为双绞线,用于传输数字信号。

需要说明的是,在本公开的一些实施例中,转向控制器52可以与方向盘控制器51进行通信,并且转向控制器52可与自动驾驶控制单元70、智能设备200和服务器300进行通信。在本公开的另一些实施例中,在智能设备200为车载智能设备,且车载智能设备、转向控制器52与方向盘控制器51均连接到车辆的通信总线(进行有线通信)上时,转向控制器52可与自动驾驶控制单元70、智能设备200和服务器300进行通信,同时方向盘控制器51还可直接与车载智能设备进行通信。
需要说明的是,在本公开的一些实施例中,方向盘10可为一个或多个,也就是说,方向盘10可为M个,M为正整数。以下以方向盘10为M个为例,对车辆的转向控制系统进行描述。

M个方向盘转角传感器20可与M个方向盘10对应相连,具体地,每个方向盘10可通过转向管柱与对应的方向盘转角传感器20进行连接,或者,每个方向盘转角传感器20也可集成在对应的方向盘10上。每个方向盘转角传感器20用于采集对应的方向盘20的转动信息例如方向盘10的转动角度和转动速度。
每个方向盘驱动单元30与对应的方向盘10相连,每个方向盘驱动单元30用于驱动对应的方向盘10转动以及向对应的方向盘10施加转向力矩。也就是说,每个方向盘驱动单元30可在控制模块50的控制下驱动对应的方向盘10转动,以保持至少一个方向盘与车轮的转动角度同步,并且,每个方向盘驱动单元30还可在对应的方向盘10被驾驶员操作时向对应的方向盘10施加转向力矩,从而给方向盘10提供反方向力矩,保证驾驶员手感舒适性。也就是说,当方向盘10在驾驶员的操作(转动)下顺时针转动时,方向盘驱动单元30给方向盘10施加逆时针方向的力矩,而当方向盘10在驾驶员的操作下逆时针转动时,方向盘驱动单元30给方向盘10施加时顺针方向的力矩。

实施例一:
基于图4至图6实施例的车辆转向控制系统,本公开提出了一种车辆以及车辆的转向控制系统和方法、车载智能设备及其控制方法以及移动智能设备及其控制方法。
根据本公开的一个实施例,控制模块50用于在车辆进入方向盘驾驶模式之前,获取车轮100的转动信息,并根据车轮100的转动信息对方向盘驱动单元30进行控制以驱动方向盘10转动,直至方向盘10的转动角度与车轮的转动角度相一致。
控制模块50包括方向盘控制器51和转向控制器52,方向盘控制器51与转向控制器52进行通信,转向控制器52用于在车辆进入方向盘驾驶模式之前,获取车轮100的转动信息,并将车轮100的转动信息发送给方向盘控制器51,方向盘控制器51根据车轮100的转动信息对方向盘驱动单元30进行控制以驱动方向盘10转动,直至方向盘10的转动角度与车轮100的转动角度相一致。
需要说明的是,方向盘驾驶模式可指驾驶员通过操作方向盘转动以控制车辆的行驶方向,即言,在方向盘驾驶模式,转向控制器52根据方向盘的转动角度控制车轮100的转动角度。
可以理解的是,在车辆未处于方向盘驾驶模式时,方向盘10与车轮100的转动角度可保持一致,也可不保持一致。
在车辆进入方向盘驾驶模式之前,例如,在车辆启动时或车辆退出自动驾驶模式时,转向控制器52可以传递车轮100的转动信息到方向盘控制器51,方向盘控制器51可根据接收到的车轮100的转动信息控制方向盘10,以使方向盘10的转动角度与车轮100的转动角度相一致,即使方向盘10的转动角度与车轮100的转动角度相对应,从而保持方向盘10与车轮100的转动角度同步。
由此,在本公开的实施例中,在车辆启动时,方向盘控制器51可根据接收到的车轮100的转动信息控制方向盘10,从而可确保方向盘10的转动角度与车轮100的转动角度保持一致。并且,在车辆处于自动驾驶状态时,如果需要驾驶员进行接管,那么,方向盘控制器51可根据接收到的车轮100的转动信息控制方向盘10转动,直至与车轮100的转动角度保持一致,从而可确保方向盘10的转动角度与车轮100的转动角度保持一致,确保驾 驶员能准确判断车辆运行方向,防止车辆发生危险,还能够有效提醒驾驶员进行驾驶,即当驾驶员发现方向盘转动时可以判断此时自动驾驶需要人工干预。
根据本公开的一个实施例,如图6所示,控制模块50例如转向控制器52可与车辆的自动驾驶控制单元70进行通信,当车辆的自动驾驶控制单元70通过接收组件71例如退出自动驾驶模式的按钮接收到驾驶员的退出自动驾驶指令或者自动驾驶控制单元70自身出现故障或者车辆所处的驾驶环境不满足自动驾驶条件时,自动驾驶控制单元70控制车辆从自动驾驶模式切换至方向盘驾驶模式。
可以理解的是,自动驾驶控制单元70可控制车辆进行自动驾驶,例如可对车辆的转向、加速、减速、灯光以及雨刮等进行控制。自动驾驶模式是指自动驾驶控制单元70自动控制车辆行驶,无需驾驶员操作方向盘10。
具体而言,当车辆处于自动驾驶模式时,自动驾驶控制单元70可监测是否接收到驾驶员的退出自动驾驶指令,如果接收到驾驶员的退出自动驾驶指令即驾驶员按下退出自动驾驶的按钮,则驾驶员想要主动接管车辆,此时自动驾驶控制单元70控制车辆退出自动驾驶模式,转向控制器52将车轮100的转动信息发送到方向盘控制器51,方向盘控制器51根据接收到的车轮100的转动信息控制方向盘10,以使方向盘10的转动角度与车轮100的转动角度相一致。
自动驾驶控制单元70还可判断是否自身是否出现故障,如果自动驾驶控制单元70自身出现故障例如自动驾驶传感器故障,则自动驾驶控制单元70判断需要驾驶员接管车辆,此时自动驾驶控制单元70控制车辆退出自动驾驶模式,转向控制器52将车轮100的转动信息发送到方向盘控制器51,方向盘控制器51根据接收到的车轮100的转动信息控制方向盘10,以使方向盘10的转动角度与车轮100的转动角度相一致。
自动驾驶控制单元70还可监测车辆周边的环境以判断车辆所处的驾驶环境是否满足自动驾驶条件,如果车辆所处的驾驶环境不满足自动驾驶条件即车辆周边环境复杂(例如处于住宅小区内),则自动驾驶控制单元70判断需要驾驶员接管车辆,此时自动驾驶控制单元70控制车辆退出自动驾驶模式,转向控制器52将车轮100的转动信息发送到方向盘控制器51,方向盘控制器51根据接收到的车轮100的转动信息控制方向盘10,以使方向盘10的转动角度与车轮100的转动角度相一致。
由此,在驾驶员想要主动接管车辆,或自动驾驶控制单元70判断需要驾驶员接管车辆时,可控制方向盘进行转动,进而保持方向盘的转动角度与车辆的转动角度保持一致,方便驾驶员接管。
在本公开的一些实施例,在方向盘10未被控制时,即方向盘10未被驾驶员操作且方向盘10无需与车轮同步,方向盘10可以被收纳到收纳腔体内以使座舱具有更多空间。
根据本公开的一个实施例,转向控制器52用于在车辆处于自动驾驶模式时接收自动驾驶控制单元70发送的转动信息,并根据自动驾驶控制单元70发送的转动信息对转向机构40进行控制,以使转向机构40根据自动驾驶控制单元70发送的转动信息驱动车辆的车轮100转动。
当车辆处于自动驾驶模式时,自动驾驶控制单元70可以传递转动信息例如转动角度到转向控制器52,转向控制器52可根据自动驾驶控制单元70发送的转动信息控制转向电机42,以使转向电机42通过转向器41驱动车轮100旋转到相应的角度。
转向控制器52可接收自动驾驶控制单元70发送的转动信息,并根据转动信息驱动转向电机42进行转动,同时,转向控制器52还通过车轮转角传感器60监测车轮100的转动信息,在监测车轮100转动到自动驾驶控制单元70预期的角度时,停止驱动转向电机42。
由此,在车辆处于自动驾驶模式时,转向控制器52根据自动驾驶控制单元70的转动信息控制车轮100转动,无需方向盘,方向盘驱动单元30可以不控制方向盘进行转动。
根据本公开的一个实施例,控制模块50例如方向盘控制器51通过车辆的通信总线例如CAN网络与车载智能设备进行通信,车载智能设备在监控到车载智能设备的目标程序运行时,获取车辆的状态信息和方向盘信息,并在车辆处于自动驾驶模式时,根据方向盘10的转动信息对车载智能设备的目标对象进行控制。

车载智能设备可根据用户的指令控制目标程序运行,并且,用户可在目标程序运行后操作方向盘,方向盘控制器51读取方向盘10的转动角度和转动速度,并将方向盘10的转动角度和转动速度发送到通信总线上,车载智能设备在监测到目标程序运行后,可直接通过车辆的通信总线读取信息,例如可先通过通信总线读取车辆的状态信息以判断工作模式,并在车辆处于自动驾驶模式时,主动通过通信总线读取方向盘10的转动信息,并根据方向盘10的转动信息对目标对象进行控制;又如,可先通过通信总线读取车辆的状态信息和方向盘10的转动信息,然后根据车辆的状态信息判断工作模式,并在车辆处于自动驾驶模式时,根据方向盘10的转动信息对目标对象进行控制。
可以理解的是,车载智能设备在车辆处于自动驾驶模式且监测到目标程序运行之后可显示提醒信息以提示用户操作方向盘。
另外,在其他一些实施例中,车载智能设备在车辆处于自动驾驶模式之后,还可对方向盘的使用状态进行判断,如果方向盘处于使用中例如遥控其他设备,则不再根据方向盘10的转动信息对目标对象进行控制,如果方向盘未处于使用中,则根据方向盘10的转动信息对目标对象进行控制。
在本公开一些实施例中,目标程序可为游戏程序例如模拟赛车游戏,目标对象可为游戏中的模拟对象,例如模拟赛车等。举例来说,当目标程序为模拟赛车游戏时,用户可触发模拟赛车游戏运行并对方向盘进行操作,方向盘控制器51读取方向盘10的转动角度和转动速度,并将方向盘10的转动角度和转动速度发送到通信总线上,车载智能设备在车辆处于自动驾驶模式且监测到目标程序运行后,可通过通信总线直接读取方向盘10的转动信息,并对方向盘10的转动信息进行处理以得到目标对象的转动信息(包括转动角度、或转动速度、或转动角度和转动速度),然后根据目标对象的转动信息对目标对象进行转向控制,例如模拟赛车游戏中的模拟赛车可根据得到的目标对象的转动角度和转动速度转动。
由此,用车辆的实体方向盘对车载智能设备进行遥控控制,在保证正常驾驶的同时兼顾乘客娱乐。
在一些实施例中,控制模块50例如转向控制器52可与移动智能设备进行无线通信,移动智能设备在监控到移动智能设备的目标程序运行时向控制模块50即转向控制器52发送请求指令,并接收控制模块20发送车辆的状态信息和方向盘信息;移动智能设备在车辆处于自动驾驶模式时,根据方向盘10的转动信息对移动智能设备的目标对象进行控制。
需要说明的是,移动智能设备可指并未安装在车辆上的智能设备。转向控制器52在接收到请求指令之后可将车辆的状态信息和方向盘信息一同发送给移动智能设备。或者,转向控制器52在接收到请求指令之后可将车辆的状态信息发送给移动智能设备,移动智能设备在判断车辆处于自动驾驶模式时可向转向控制器52发送控制请求,转向控制器52再根据控制请求获取方向盘信息,并将方向盘信息实时发送给移动智能设备,移动智能设备即可根据方向盘10的转动信息对目标对象进行控制。
可以理解的是,目标程序可为移动智能设备上安装的应用程序例如游戏程序或遥控程序,目标对象可以是虚拟对象例如移动智能设备上显示的虚拟方向盘、虚拟车辆,或者,目标对象可以是实体对象,例如移动智能设备自身或移动智能设备上的转动部件(例如无人机的转动部件)。

另外,在其他一些实施例中,移动智智能设备在车辆处于自动驾驶模式之后,还可对方向盘的使用状态进行判断,如果方向盘处于使用中例如遥控其他设备,则不再根据方向盘10的转动信息对目标对象进行控制,如果方向盘未处于使用中,则根据方向盘10的转动信息对目标对象进行控制。
在本公开一些实施例中,目标程序可为游戏程序例如模拟赛车游戏,目标对象可为游戏中的模拟对象,例如模拟赛车等。或者,目标程序可为无人机遥控程序,目标对象可为无人机。举例来说,当目标程序为无人机遥控程序时,用户可触发无人机遥控程序运行并对方向盘进行操作,方向盘控制器51读取方向盘10的转动角度和转动速度,并将方向盘10的转动角度和转动速度发送给转向控制器52,转向控制器52将方向盘10的转动角度和转动速度实时发送给无人机,无人机在车辆处于自动驾驶模式且监测到目标程序运行后,可对方向盘10的转动信息进行处理以得到目标对象的转动信息(包括转动角度、或转动速度、或转动角度和转动速度),然后根据目标对象的转动信息对无人机进行转向控制,以对无人机进行遥控控制。
由此,用车辆的实体方向盘对移动智能设备进行遥控控制,在保证正常驾驶的同时兼顾乘客娱乐。
需要说明的是,当车辆处于自动驾驶模式时车辆的车轮100可不随方向盘的转动而旋转。并且,当车辆处于方向盘驾驶模式时,车载智能设备或移动设备可自动退出目标程序,停止根据方向盘10的转动信息对目标对象进行控制。其中,车载智能设备或移动设备根据控制模块502实时发送的车辆的状态信息判断车辆进入方向盘驾驶模式。根据本公开的一个实施例,转向控制器52用于在车辆进入方向盘驾驶模式之后,获取方向盘10的转动信息,并根据方向盘10的转动信息对转向机构40进行控制,以使转向机构40按照方向盘 10的转动信息驱动车辆的车轮100转动。同时方向盘控制器51控制方向盘驱动单元30向方向盘10施加转向力矩。
也就是说,当驾驶员通过方向盘10进行操作时,方向盘控制器51可以传递方向盘10的转动信息到转向控制器52,转向控制器52根据接收到的转动信息控制转向机构40,以使车轮100旋转到相应的角度。
转向控制器52可接收方向盘控制器51发送的方向盘10的转动信息,并根据方向盘10的转动信息驱动转向电机42运转,同时,转向控制器52还通过车轮转角传感器60监测车轮100的转动信息例如转动角度,在监测车轮100转动到方向盘10的转动角度时,停止驱动转向电机42,实时保证车轮角度与方向盘角度一致。
可以理解的是,方向盘控制器51可通过方向盘转角传感器20采集方向盘10的转动信息以确定驾驶员的转向意愿;方向盘驱动单元30可模拟转向力矩,以使驾驶员有较舒适的转向力。转向控制器52可接收方向盘控制器51传输的方向盘10的转动信息,并判断车辆是否在方向盘驾驶模式,当车辆处于方向盘驾驶模式时,转向控制器52根据方向盘10的转动信息来带动转向机构40实现转向。当方向盘10进入预设工作模式且车辆未在方向盘驾驶模式时,转向控制器52可获取方向盘10的转向角度和转向速度,并通过有线或无线方式发送给智能设备200,或者智能设备200可以直接进行判断,并在判断方向盘进入预设工作模式且车辆未在方向盘驾驶模式之后主动采集方向盘10的转动信息。
由此,在驾驶员进行驾驶操作时,方向盘10的转动角度可与车轮100的转动角度保持一致。
如上所述,在本公开实施例中,在整车上电之后,转向控制器52可判断车辆是否成功启动,如果车辆启动失败,则转向控制器52不接收方向盘驱动单元30或自动驾驶控制单元70的转动信息,车轮100的角度保持不变。此时,车载智能终端可判断是否监测到目标程序运行,如果监测到目标程序,则读取方向盘10的转动角度和转动速度,并根据方向盘10的转动角度和转动速度对目标对象进行控制。或者,移动智能终端可判断是否监测到目标程序运行,如果监测到目标程序,则向转向控制器52发送请求指令,并接收转向控制器52发送的方向盘10的转动角度和转动速度,并根据方向盘10的转动角度和转动速度对目标对象进行控制。
如果车辆成功启动,转向控制器52则进一步判断车辆是否处于自动驾驶模式,如果未处于自动驾驶模式且处于方向盘控制模块,转向控制器52接收方向盘驱动单元30发送的方向盘的转动信息,并驱动转向电机42,同时通过车轮转角传感器60检测车轮100的转动信息,使车轮100的角度保持与方向盘10的角度一致,实时相应驾驶员的转向请求。
如果车辆处于自动驾驶模式,转向控制器52接收自动驾驶控制单元70发送的转动信息, 并根据自动驾驶控制单元70发送的转动信息驱动转向电机42,同时通过车轮转角传感器60检测车轮100的转动信息,使车轮100的角度保持与自动驾驶控制单元70的要求一致。此时,车载智能终端可判断是否监测到目标程序运行,如果监测到目标程序,则读取方向盘10的转动角度和转动速度,并根据方向盘10的转动角度和转动速度对目标对象进行控制。或者,移动智能终端可判断是否监测到目标程序运行,如果监测到目标程序,则向转向控制器52发送请求指令,并接收转向控制器52发送的方向盘10的转动角度和转动速度,并根据方向盘10的转动角度和转动速度对目标对象进行控制。
在车辆进行自动驾驶模式的过程中,自动驾驶控制单元70判断是否接收到驾驶员的退出指令或自动驾驶控制单元70判断是否出现自身故障或者判断驾驶环境是否不满足自动驾驶操作,如果接收到驾驶员的退出指令或自动驾驶控制单元70自身出现故障或者驾驶环境不满足自动驾驶操作,则转向控制器52将车轮100的转动信息发送给方向盘控制器51,方向盘控制器51判断方向盘10的转动角度是否与车轮100的转动角度相一致,如果一致,则方向盘控制器51通知转向控制器52同步成功,如果不一致,方向盘控制器51则根据车轮的转动信息对方向盘驱动单元30进行控制以驱动方向盘10转动,同时通过方向盘转角传感器20监测方向盘的转动信息,使方向盘10的角度转动到与车轮100的角度一致。
由此,本公开实施例的转向控制系统能够实现转向线控控制,当车辆处于停止状态或者车辆处于自动驾驶状态时,方向盘可不与轮胎转动信息保持一致,这时方向盘可以用于其他操作,例如当做遥控器,进行赛车游戏、控制无人机等,当用户操作或退出自动驾驶状态时,方向盘与轮胎角度保持一致。从而,本公开实施例既可以用作遥控系统,也可以在驾驶员操纵时保持与车轮同步,用作驾驶系统。
综上,根据本公开实施例提出的车辆的控制系统,控制模块分别与转向机构、车轮转角传感器、方向盘转角传感器和方向盘驱动单元电连接,控制模块在车辆进入方向盘驾驶模式之前,获取车轮的转动信息,并根据车轮的转动信息对方向盘驱动单元进行控制以驱动方向盘转动,直至方向盘的转动角度与车轮的转动角度相一致,从而,能够采用有线信号或无线信号来传递驾驶员的转向意愿,进而无需机械机构即可实现转向控制,便于自由布置方向盘的位置,且能够设置多个方向盘,并且,在车辆需要驾驶员接管驾驶时,能够确保方向盘的转动角度与车轮的转动角度保持一致,从而确保驾驶员能准确判断车辆运行方向,防止车辆发生危险。

实施例二:
基于图1至图3实施例的车辆转向控制系统,本公开提出了一种车辆以及车辆的转向控制系统和方法、服务器。
根据本公开的一个实施例,控制模块50与转向机构40、方向盘驱动单元30和方向盘转角传感器20电连接,控制模块50还与智能方向控制装置进行通信以接收智能方向控制装置发送的转动信息中的至少一个,控制模块50用于根据方向盘10的转动信息和智能方向控制装置发送的转动信息中的至少一个对转向机构40进行控制,其中,智能方向控制装置包括自动驾驶控制单元70、智能设备200和服务器300中的至少一个。
控制模块50还与自动驾驶控制单元70、智能设备200和服务器300中的至少一个进行通信以接收自动驾驶控制单元70发送的转动信息、智能设备200发送的转动信息和服务器300发送的转动信息中的至少一个,控制模块50用于根据方向盘10的转动信息、自动驾驶控制单元70发送的转动信息、智能设备200发送的转动信息和服务器30发送的转动信息中的至少一个对转向机构40进行控制。
具体而言,控制模块50例如转向控制器52可以接收自动驾驶控制单元70发送的转动信息,可以接收方向盘控制器51发送的方向盘10的转动信息,可以接收智能设备200发送的转向信息,可以通过车载通信模块接收服务器300发送的转向信息。进而,转向控制器52可根据方向盘10的转动信息、自动驾驶控制单元70发送的转动信息、智能设备200发送的转动信息和服务器30发送的转动信息中的至少一个对转向机构40进行控制,从而,采用冗余设计,通过多种方式实现对车辆转向的控制,确保车辆的行驶安全。
在一些实施例中,控制模块50例如转向控制器52用于在车辆处于自动驾驶模式时根据自动驾驶控制单元70发送的转动信息对转向机构40进行控制,以使转向机构40根据自动驾驶控制单元70发送的转动信息驱动车辆的车轮100转动,并在车辆出现自动驾驶故障时,根据方向盘10的转动信息、智能设备200发送的转动信息和服务器300发送的转动信 息中的至少一个对转向机构40进行控制。
当车辆处于自动驾驶模式时,自动驾驶控制单元70可以传递转动信息例如转动角度到转向控制器52,转向控制器52可根据自动驾驶控制单元70发送的转动信息控制转向电机42,以使转向电机42通过转向器41驱动车轮100旋转到相应的角度。
转向控制器52可接收自动驾驶控制单元70发送的转动信息,并根据转动信息驱动转向电机42进行转动,同时,转向控制器52还通过车轮转角传感器60监测车轮100的转动信息,在监测车轮100转动到自动驾驶控制单元70预期的角度时,停止驱动转向电机42。
由此,在车辆处于自动驾驶模式时,转向控制器52根据自动驾驶控制单元70的转动信息控制车轮100转动,无需方向盘,方向盘驱动单元30可以不控制方向盘进行转动。
需要说明的是,当自动驾驶控制单元70判断传感器出现故障或自动驾驶控制单元70出现故障时,判断车辆出现自动驾驶故障即自动驾驶控制单元70失效。其中,如果转向控制器52在预设时间内一直未接收到自动驾驶控制单元70的控制报文,转向控制器52则判断自动驾驶控制单元70出现故障。
根据本公开的一个实施例,在车辆出现自动驾驶故障时,可按照预设优先级顺序并根据方向盘10的转动信息、智能设备200发送的转动信息或服务器300发送的转动信息对转向机构40进行控制。其中,方向盘10的优先级高于智能设备200,且智能设备200高于服务器300。
由此,在自动驾驶控制单元失效后,可以提供多种解决方案来实现对车辆转向的控制,从而确保车辆的行驶安全。例如可以通过驾驶座的方向盘对车辆进行控制,可以通过智能设备200例如车载智能终端对车辆进行控制,可以通过服务器300对车辆进行远程控制,例如通过监控人员对车辆进行远程控制。
在本公开的一个实施例,在车辆出现自动驾驶故障之后,控制模块50还用于获取车轮100的转动信息,并根据车轮100的转动信息对方向盘驱动单元30进行控制以驱动方向盘10转动,直至方向盘10的转动角度与车轮的转动角度相一致。

由此,能够确保驾驶员能准确判断车辆运行方向,防止车辆发生危险,还能够有效提醒驾驶员进行驾驶,即当驾驶员发现方向盘转动时可以判断此时自动驾驶需要人工干预。
根据本公开的一个具体实施例,在车辆出现自动驾驶故障之后,控制模块50用于,在 接收到方向盘控制指令之后,接收方向盘10的转动信息,并根据方向盘10的转动信息对转向机构40进行控制。
可以理解的是,方向盘10的转动信息的优先级高于智能设备200发送的转动信息和服务器300发送的转动信息,进而,在接收到方向盘10的转动信息时,即使接收到智能设备200发送的转动信息和服务器300发送的转动信息,也根据方向盘10的转动信息对转向机构40进行控制。
当自动驾驶控制单元70或其传感器出现故障时,驾驶座上的驾驶员可以通过方向盘20接管对车辆的控制,此时车辆进入方向盘控制模式,方向盘20在驾驶员的操作下转动,转向控制器52获取方向盘10的转动信息,并根据方向盘10的转动信息对转向机构40进行控制,以使转向机构40按照方向盘10的转动信息驱动车辆的车轮100转动。同时,方向盘控制器51控制方向盘驱动单元30向方向盘10施加转向力矩。
具体而言,在自动驾驶控制单元70或其传感器出现故障时,转向控制器52可判断是否接收到方向盘控制指令,例如在方向盘10在驾驶员的操作下转动时判断接收到方向盘控制指令,或者方向盘10上的接管按键被触发时判断接收到方向盘控制指令。在接收到方向盘控制指令之后,车辆进入方向盘控制模式,此时驾驶员通过方向盘10对车辆进行控制,方向盘控制器51可以传递方向盘10的转动信息到转向控制器52,转向控制器52根据接收到的转动信息控制转向机构40,以使车轮100旋转到相应的角度。
转向控制器52可接收方向盘控制器51发送的方向盘10的转动信息,并根据方向盘10的转动信息驱动转向电机42运转,同时,转向控制器52还通过车轮转角传感器60监测车轮100的转动信息例如转动角度,在监测车轮100转动到方向盘10的转动角度时,停止驱动转向电机42,从而保证车轮角度与方向盘角度一致。
可以理解的是,方向盘控制器51可通过方向盘转角传感器20采集方向盘10的转动信息以确定驾驶员的转向意愿;方向盘驱动单元30可模拟转向力矩,以使驾驶员有较舒适的转向力。转向控制器52可接收方向盘控制器51传输的方向盘10的转动信息,并根据方向盘10的转动信息来带动转向机构40实现转向。
由此,在自动驾驶控制器出现故障时,优先通过方向盘10对车辆进行控制,避免车辆事故的发生。
在一些实施例中,控制模块50例如转向控制器52用于,在未接收到方向盘控制指令且接收到智能设备控制指令时,接收智能设备200发送的转动信息,并根据智能设备200发送的转动信息对转向机构40进行控制。
可以理解的是,智能设备200发送的转动信息的优先级高于服务器300发送的转动信息,进而,在未接收到方向盘10的转动信息且接收到智能设备200发送的转动信息时,即 使接收到服务器300发送的转动信息,也根据智能设备200发送的转动信息对转向机构40进行控制。
当自动驾驶控制单元70或其传感器出现故障时,驾驶员如果不能及时的接管方向盘,则可通过智能设备200对车辆进行控制,此时智能设备200可接收转向操作指令,并根据转向操作指令生成转动信息,以及将该转动信息发送给转向控制器52,转向控制器52获取智能设备200发送的转动信息,并根据智能设备200发送的转动信息对转向机构40进行控制,以使转向机构40按照智能设备200发送的转动信息驱动车辆的车轮100转动。
具体而言,在自动驾驶控制单元70或其传感器出现故障时,转向控制器52在判断未接收到方向盘控制指令之后,进一步判断是否接收到智能终端控制指令,例如智能终端在接收到驾驶员的转动操作指令时判断接收到智能终端控制指令,或者智能终端上的接管按键被触发时判断接收到智能终端控制指令。在接收到智能终端控制指令之后,驾驶员通过智能设备200进行转向控制,智能设备200可以传递转动信息到转向控制器52,转向控制器52根据智能设备200发送的转动信息控制转向机构40,以使车轮100旋转到相应的角度。转向控制器52可接收智能设备200发送的方向盘10的转动信息,并根据智能设备200发送的转动信息驱动转向电机42运转,同时,转向控制器52还通过车轮转角传感器60监测车轮100的转动信息例如转动角度,在监测车轮100转动到智能设备200所提供的转动角度时,停止驱动转向电机42,从而保证车轮角度与智能设备200所提供的转动角度一致。
可以理解的是,智能设备200可显示虚拟方向盘,驾驶员可通过虚拟方向盘输入转向操作指令,智能设备200可根据转向操作指令生成虚拟方向盘的转动信息例如转动角度,并将转动信息发送给转向控制器52,转向控制器52可接收智能设备200传输的虚拟方向盘的转动信息,并根据虚拟方向盘的转动信息来带动转向机构40实现转向,使虚拟方向盘的转动角度与车轮的转动角度保持一致。
由此,在自动驾驶控制器出现故障时,且驾驶员来不及接管方向盘时,通过智能设备200对车辆进行控制,例如智能终端200中的虚拟方向盘对车辆进行控制,避免车辆事故的发生,确保车辆的行驶安全。
需要说明的是,在车辆出现自动驾驶故障之后,控制模块50例如转向控制器52还可获取车轮100的转动信息例如转动角度,并将车轮100的转动信息发送给智能终端200,以提示车轮100的转动角度。例如,当智能设备200显示虚拟方向盘时,智能设备200可根据车轮100的转动信息控制虚拟方向盘转动,直至虚拟方向盘的转动角度与车轮的转动角度相一致。
由此,能够确保驾驶员能准确判断车辆运行方向,防止车辆发生危险。
在一些实施例中,控制模块50例如转向控制器52用于,在未接收到方向盘控制指令 且未接收到智能设备控制指令时,获取车辆周边的图像信息,并将车辆周边的图像信息和接管指令发送至服务器300,并在接收到服务器300发送的转动信息时,根据服务器300发送的转动信息对转向机构40进行控制。
可以理解的是,在未接收到方向盘控制指令且未接收到智能设备控制指令时,可请求服务器300接管车辆的控制,此时可根据服务器300发送的转动信息对转向机构40进行控制。
当自动驾驶控制单元70或其传感器出现故障时,驾驶员如果不能及时的接管方向盘,且无法通过智能设备200对车辆进行控制时,此时转向控制器52可通过车载摄像头采集车辆周边的图像信息,并将车辆周边的图像信息和接管指令一同发送给服务器300,服务器300可接收外部输入的转向操作指令以生成转动信息或者直接根据车辆周边的图像信息生成转动信息,然后,服务器300将生成的转动信息发送给转向控制器52,转向控制器52接收服务器300发送的转动信息,并根据服务器300发送的转动信息对转向机构40进行控制,以使转向机构40按照服务器300发送的转动信息驱动车辆的车轮100转动。
具体而言,当通过服务器300对车辆进行转向控制时,服务器300可以传递转动信息到转向控制器52,转向控制器52根据服务器300发送的转动信息控制转向机构40,以使车轮100旋转到相应的角度。转向控制器52可接收服务器300发送的方向盘10的转动信息,并根据服务器300发送的转动信息驱动转向电机42运转,同时,转向控制器52还通过车轮转角传感器60监测车轮100的转动信息例如转动角度,在监测车轮100转动到服务器300所提供的转动角度时,停止驱动转向电机42,从而保证车轮角度与服务器300所提供的转动角度一致。
可以理解的是,车辆的多个车载摄像头可设置在车身周边以采集车辆周边的图像信息(可以是视频信息),其中,多个车载摄像头可在设置在车身前方、两侧以及后方,转向控制器52可以通过V2X通讯模块80将车载摄像头采集的车辆周边图像信息及接管指令发送给路边V2X通讯设施90,路边V2X通讯设施90通过4G或5G通信方式将车辆周边图像信息及接管指令传送给服务器300。
在一个实施例中,服务器300可将图像信息实时推送至后台监控人员的监控终端,后台监控人员通过监控终端的界面获得车辆周边图像信息以确定车辆周边环境,监控人员可结合车辆周边环境并通过室内仿真方向盘输入转向操作指令,以实现对车辆的远程控制。服务器300实时采集室内仿真方向盘的转动信息并将转动信息远程传送至车辆的V2X通讯模块80,V2X通讯模块80将来自服务器300的转动信息令传送给转向控制器52,转向控制器52接收服务器300发送的转动信息,并根据服务器300发送的转动信息对转向机构40进行控制。
在另一个实施例中,服务器300可对图像信息进行分析,并根据分析结果计算车辆行驶路线,以获得最佳的方向盘控制信号即生成转动信息例如转动角度和转动速度,并将转动信息远程传送至车辆的V2X通讯模块80,V2X通讯模块80将来自服务器300的转动信息令传送给转向控制器52,转向控制器52接收服务器300发送的转动信息,并根据服务器300发送的转动信息对转向机构40进行控制。

根据本公开的一个实施例,控制模块50例如方向盘控制器51通过车辆的通信总线例如CAN网络与车载智能设备进行通信,当M=1时,车载智能设备在监控到目标程序运行时,获取车辆的状态信息和方向盘信息,并在车辆未处于方向盘驾驶模式且未处于自动驾驶模式时,根据方向盘10的转动信息对目标对象进行控制。
可以理解的是,车辆的状态信息可包括车辆所处的驾驶模式,例如车辆是否处于方向盘驾驶模式,或者是否处于自动驾驶模式,或者是否处于停车状态等,方向盘信息可包括方向盘的转动信息、方向盘的使用情况以及方向盘的标志信息等。

另外,在其他一些实施例中,车载智能设备在车辆未处于方向盘驾驶模式之后,还可对方向盘的使用状态进行判断,如果方向盘处于使用中例如遥控其他设备,则不再根据方 向盘10的转动信息对目标对象进行控制,如果方向盘未处于使用中,则根据方向盘10的转动信息对目标对象进行控制。
在本公开一些实施例中,目标程序可为游戏程序例如模拟赛车游戏,目标对象可为游戏中的模拟对象,例如模拟赛车等。举例来说,当目标程序为模拟赛车游戏时,用户可触发模拟赛车游戏运行并对方向盘进行操作,方向盘控制器51读取方向盘10的转动角度和转动速度,并将方向盘10的转动角度和转动速度发送到通信总线上,车载智能设备在车辆未处于方向盘驾驶模式且未处于自动驾驶模式、且监测到目标程序运行后,可通过通信总线直接读取方向盘10的转动信息,并对方向盘10的转动信息进行处理以得到目标对象的转动信息(包括转动角度、或转动速度、或转动角度和转动速度),然后根据目标对象的转动信息对目标对象进行转向控制,例如模拟赛车游戏中的模拟赛车可根据得到的目标对象的转动角度和转动速度转动。
在本公开的其他实施例中,M=1时,控制模块50例如转向控制器52可在车辆处于自动驾驶模式时,不对方向盘10进行控制,即方向盘10与车轮100可不保持同步。此时,车载智能设备在根据方向盘10的转动信息对目标对象进行控制之前只需判断车辆是否处于方向盘驾驶模式,即在车辆未处于方向盘驾驶模式例如处于自动驾驶模式或停止状态时,根据方向盘10的转动信息对目标对象进行控制。应理解,自动驾驶模式下,方向盘10与车轮100可不保持同步的时,车载智能设备在自动驾驶模式下的控制方式与前述实施例中车辆未处于方向盘驾驶模式且未处于自动驾驶模式时的控制方式基本一致,这里不再详细赘述。
由此,用车辆的实体方向盘对车载智能设备进行遥控控制,在保证正常驾驶的同时兼顾乘客娱乐。
在一些实施例中,控制模块50例如转向控制器52可与移动智能设备进行无线通信,移动智能设备在监控到目标程序运行时向控制模块50即转向控制器52发送请求指令,并接收控制模块20发送车辆的状态信息和方向盘信息;移动智能设备在车辆未处于所述方向盘驾驶模式且未处于自动驾驶模式时,根据方向盘10的转动信息对目标对象进行控制。
需要说明的是,移动智能设备可指并未安装在车辆上的智能设备。转向控制器52在接收到请求指令之后可将车辆的状态信息和方向盘信息一同发送给移动智能设备。或者,转向控制器52在接收到请求指令之后可将车辆的状态信息发送给移动智能设备,移动智能设备在判断车辆未处于方向盘驾驶模式且未处于自动驾驶模式时可向转向控制器52发送控制请求,转向控制器52再根据控制请求获取方向盘信息,并将方向盘信息实时发送给移动智能设备,移动智能设备即可根据方向盘10的转动信息对目标对象进行控制。
可以理解的是,目标程序可为移动智能设备上安装的应用程序例如游戏程序或遥控程 序,目标对象可以是虚拟对象例如移动智能设备上显示的虚拟方向盘、虚拟车辆,或者,目标对象可以是实体对象,例如移动智能设备自身或移动智能设备上的转动部件(例如无人机的转动部件)。
当方向盘10为一个时,移动智能设备可根据用户的指令控制目标程序运行,并且,用户可在目标程序运行后操作方向盘,方向盘控制器51读取方向盘10的转动角度和转动速度,并将方向盘10的转动角度和转动速度发送给转向控制器52。移动智能设备在监测到目标程序运行后,可向转向控制器52发送请求指令,转向控制器52在接收到请求指令之后向移动智能设备反馈信息。
例如转向控制器52可向移动智能设备发送车辆的状态信息,移动智能设备可根据车辆的状态信息进行工作模式判断,并在车辆未处于方向盘驾驶模式且未处于自动驾驶模式时,例如处于停止状态时,再向转向控制器52发送控制请求,转向控制器52再根据控制请求获取方向盘信息,并将方向盘信息实时发送给移动智能设备,移动智能设备即可根据方向盘10的转动信息对目标对象进行控制,以及在车辆处于方向盘驾驶模式或处于自动驾驶模式时,则不再向转向控制器52发送控制请求,即不再根据方向盘10的转动信息对目标对象进行控制。
又如,转向控制器52在接收到请求指令之后可将车辆的状态信息和方向盘10的转动信息一同发送给移动智能设备,然后移动智能设备根据车辆的状态信息判断工作模式,并在车辆未处于方向盘驾驶模式且未处于自动驾驶模式时,根据方向盘10的转动信息对目标对象进行控制,以及在车辆处于方向盘驾驶模式或处于自动驾驶模式时,不再根据方向盘10的转动信息对目标对象进行控制。
可以理解的是,移动智能设备在车辆未处于方向盘驾驶模式且未处于自动驾驶模式、且监测到目标程序运行之后可显示提醒信息以提示用户操作方向盘。移动智智能设备在车辆处于方向盘驾驶模式且未处于自动驾驶模式之后可显示提醒信息以提示用户无法通过方向盘对目标对象进行控制。
另外,在其他一些实施例中,移动智智能设备在车辆未处于方向盘驾驶模式且未处于自动驾驶模式之后,还可对方向盘的使用状态进行判断,如果方向盘处于使用中例如遥控其他设备,则不再根据方向盘10的转动信息对目标对象进行控制,如果方向盘未处于使用中,则根据方向盘10的转动信息对目标对象进行控制。
在本公开一些实施例中,目标程序可为游戏程序例如模拟赛车游戏,目标对象可为游戏中的模拟对象,例如模拟赛车等。或者,目标程序可为无人机遥控程序,目标对象可为无人机。举例来说,当目标程序为无人机遥控程序时,用户可触发无人机遥控程序运行并对方向盘进行操作,方向盘控制器51读取方向盘10的转动角度和转动速度,并将方向盘 10的转动角度和转动速度发送给转向控制器52,转向控制器52将方向盘10的转动角度和转动速度实时发送给无人机,无人机在车辆未处于方向盘驾驶模式且未处于自动驾驶模式、且监测到目标程序运行后,可对方向盘10的转动信息进行处理以得到目标对象的转动信息(包括转动角度、或转动速度、或转动角度和转动速度),然后根据目标对象的转动信息对无人机进行转向控制,以对无人机进行遥控控制。
由此,用车辆的实体方向盘对移动智能设备进行遥控控制,在保证正常驾驶的同时兼顾乘客娱乐。
需要说明的是,当车辆未处于方向盘驾驶模式且未处于自动驾驶模式时车辆的车轮100可不随方向盘的转动而旋转。并且,当车辆处于方向盘驾驶模式或处于自动驾驶模式时,车载智能设备或移动设备可自动退出目标程序,停止根据方向盘10的转动信息对目标对象进行控制。其中,车载智能设备或移动设备根据控制模块502实时发送的车辆的状态信息判断车辆进入方向盘驾驶模式或自动驾驶模式。
在本公开的其他实施例中,M=1时,控制模块50例如转向控制器52可在车辆处于自动驾驶模式时,不对方向盘10进行控制,即方向盘10与车轮100可不保持同步。此时,移动智能设备在根据方向盘10的转动信息对目标对象进行控制之前只需判断车辆是否处于方向盘驾驶模式,即在车辆未处于方向盘驾驶模式例如处于自动驾驶模式或停止状态时,根据方向盘10的转动信息对目标对象进行控制。应理解,自动驾驶模式下,方向盘10与车轮100可不保持同步的时,移动智能设备在自动驾驶模式下的控制方式与前述实施例中车辆未处于方向盘驾驶模式且未处于自动驾驶模式时的控制方式基本一致,这里不再详细赘述。
如上所述,当M=1时,本公开实施例的控制流程可如下:
整车上电之后,转向控制器52判断车辆是否处于停止状态,如果未处于停止即处于方向盘驾驶模式或处于自动驾驶模式,转向控制器52则读取方向盘10的转动角度和转动速度,并驱动转向机构40按照转动角度和转动速度旋转车轮,
如果处于停止状态,则车载智能终端可判断是否监测到目标程序运行,如果监测到目标程序,则读取方向盘10的转动角度和转动速度,并根据方向盘10的转动角度和转动速度对目标对象进行控制。
或者,如果处于停止状态,则移动智能终端可判断是否监测到目标程序运行,如果监测到目标程序,则向转向控制器52发送请求指令,并接收转向控制器52发送的方向盘10的转动角度和转动速度,并根据方向盘10的转动角度和转动速度对目标对象进行控制。
根据本公开的另一个实施例,控制模块50例如转向控制器52进一步用于在车辆处于方向盘驾驶模式时,获取预设的优先级信息以确定M个方向盘10的优先级排序,并根据 M个方向盘10的优先级排序确定M个方向盘10中用于控车的方向盘,并根据用于控车的方向盘的转动信息对转向机构40进行控制,以使转向机构40按照用于控车的方向盘的转动信息驱动车辆的车轮100转动。
当M>1时,方向盘控制器51可通过M个方向盘转角传感器20分别采集对应的M个方向盘20的转动信息以确定驾驶员的转向意愿;每个方向盘驱动电机31可模拟转向力矩,以使驾驶员有较舒适的转向力。转向控制器52可接收M个方向盘控制器51发送的方向盘10的转动信息,并判断车辆是否在方向盘驾驶模式,当车辆处于方向盘驾驶模式时,转向控制器52根据M个方向盘10的转动信息和车轮100的转动信息来带动转向机构40以实现转向。
应当理解的是,预设的优先级信息可为出厂时预先设定的优先级信息,也可为用户自行设定的优先级信息。即言,可根据用户自身需求设置M个方向盘10的优先级排序,例如,以主驾方向盘和副驾方向盘为例,可设置主驾方向盘的优先级高于副驾方向盘的优先级,或者可设置副驾方向盘的优先级高于主驾方向盘的优先级。应理解,本文的优先级是根据方向盘控制车轮的级别设置的,而不是根据方向盘控制其他智能设备的级别来设置的。
需要说明的是,用于控车的方向盘是指当前控制车辆行驶方向的方向盘,换言之,车轮的转动角度至少与用于控车的方向盘的转动角度相一致。
根据本公开的一个实施例,方向盘为多个,与每个方向盘一一对应的多个方向盘驱动单元,每个方向盘驱动单元用于驱动与其对应的方向盘转动,其中,控制模块用于在车辆进入方向盘驾驶模式之前,获取车轮的转动信息,并根据车轮的转动信息对方向盘驱动单元进行控制以驱动方向盘转动,直至方向盘的转动角度与车轮的转动角度相一致包括:控制模块用于在车辆进入方向盘驾驶模式之前,获取车轮的转动信息,并根据车轮的转动信息对待控车的方向盘驱动单元进行控制以驱动待控车的方向盘转动,直至待控车的方向盘的转动角度与车轮的转动角度相一致。
举例来说,假设车辆上安装有三个方向盘A、B、C,且方向盘A的优先级大于方向盘B的优先级,方向盘B的优先级大于方向盘C的优先级(在后面实施例中,方向盘A、B、C的优先级均参照此排序),当确定方向盘B为用于控车的方向盘时,控制模块50可获取方向盘B的转动信息,并根据方向盘B的转动角度对转向机构40进行控制,直至转车轮100的转动角度与方向盘B的转动角度相一致。
还需说明的是,控制模块50在根据用于控车的方向盘的转动信息对车轮100进行控制时,其他方向盘可以与车轮100同步转动,也可不与车轮同步转动,即言,当方向盘B为用于控车的方向盘时,方向盘A和C可以与车轮100的转动保持同步,也可不与车轮100的转动保持同步。
在本公开的一个具体实施例中,控制模块50例如转向控制器52用于在确定用于控车的方向盘时,确定M个方向盘中被操作的至少一个方向盘,并将被操作的至少一个方向盘中优先级最高的方向盘的作为用于控车的方向盘。也就是说,包括一个方向盘转动,则直接将该方向盘作为用于控车的方向盘,即直接使用该方向盘控制车辆的行驶方向;而当多个方向盘同时转动时,则将高优先级的方向盘作为用于控车的方向盘,即使用高优先级的方向盘控制车辆的行驶方向。
举例来说,当方向盘B和方向盘C同时被用户操作而转动时,由于方向盘B的优先级高于方向盘C的优先级,因此,控制模块50可将方向盘B作为用于控车的方向盘,并根据方向盘B的转动角度对转向机构40进行控制。
根据本公开的一个实施例,控制模块50例如转向控制器52进一步用于在根据用于控车的方向盘的转动信息对转向机构40进行控制时,还确定除用于控车的方向盘以外的其他方向盘中的待同步方向盘,并根据车轮100的转动信息对待同步方向盘进行控制,以使待同步方向盘与车轮100保持同步。其中,非待同步方向盘与车轮100可不保持同步。
需要说明的是,待同步方向盘是指,当前未控制车辆行驶方向,但需要与车轮同步的方向盘。
控制模块50在按照用于控车的方向盘的转动信息控制车轮100转动时,还可实时根据车轮100的转动信息驱动待同步方向盘转动,以使待同步方向盘与车轮100保持同步,从而,便于用户接管车辆。此时,非待同步方向盘与车轮100可不保持同步。
举例来说,当方向盘B为用于控车的方向盘,方向盘A为待同步方向盘时,控制模块50可根据方向盘B的转动角度对转向机构40进行控制,直至转车轮100的转动角度与方向盘B的转动角度相一致,并可根据车轮100的转动角度对方向盘A进行控制,直至方向盘A的转动角度与转车轮100的转动角度相一致。此时,方向盘C为非待同步方向盘,方向盘C可与车轮100可不保持同步。
根据本公开的另一个实施例,控制模块50例如转向控制器52进一步用于在根据用于控车的方向盘的转动信息对转向机构40进行控制时,还确定除用于控车的方向盘以外的其他方向盘中的待同步方向盘,并在确定待同步方向盘接管控车时,根据车轮100的转动信息对接管控车的待同步方向盘进行控制,以使与接管控车的待同步方向盘与车轮100保持同步。
控制模块50在按照用于控车的方向盘的转动信息控制车轮100转动时,待同步方向盘与车轮100可先不保持同步,而在待同步方向盘需要接管控车时,再根据车轮100的转动信息驱动接管控车的待同步方向盘转动,以使接管控车的待同步方向盘与车轮100保持同步,从而,便于用户接管车辆。此时,非待同步方向盘与车轮100可不保持同步。
需要说明的是,待同步方向盘可为一个或多个,可选择待同步方向盘中的一个接管控车,进而该接管控车的待同步方向盘与车轮100保持同步。而其他未接管控车的待同步方向盘可与车轮100保持同步,也可不与车轮100保持同步,本公开对此不做限定。
应理解,控制模块50可在用户控车的方向盘出现故障或用户控车的方向盘停止控车例如接收到用户输入的退出接管指令时,确定待同步方向盘接管控车。或者,控制模块50可接收到任一待同步方向盘的接管指令且该待同步方向盘的优先级高于用于控车的方向盘的优先级时,确定该待同步方向盘接管控车。
举例来说,当方向盘B为用于控车的方向盘,方向盘A为待同步方向盘时,控制模块50可根据方向盘B的转动角度对转向机构40进行控制,直至车轮100的转动角度与方向盘B的转动角度相一致,而方向盘A与车轮100可不保持同步,直至接收到方向盘A的接管指令。在接收到方向盘A的接管指令时,控制模块50在根据车轮100的转动角度对方向盘A进行控制,直至方向盘A的转动角度与转车轮100的转动角度相一致,并在方向盘A的转动角度与转车轮100的转动角度相一致之后,根据方向盘A的转动角度对车轮100进行控制。此时,方向盘C为非待同步方向盘,方向盘C可与车轮100可不保持同步。
在本公开的一个具体实施例中,控制模块50例如转向控制器52用于将M个方向盘中优先级高于用于控车的方向盘的优先级的方向盘作为待同步方向盘;或者控制模块50用于将M个方向盘中优先级高于用于控车的方向盘的优先级的方向盘和M个方向盘中的默认方向盘一同作为待同步方向盘。
需要说明的是,默认方向盘可为出厂时默认设定的方向盘,例如,在出产设定时,默认方向盘可为优先级最高的方向盘,可以为主驾方向盘。
当M个方向盘10中不存在默认方向盘时,可将高于用于控车的方向盘的优先级的方向盘作为待同步方向盘,这样,控制模块50在根据用于控车的方向盘的转动信息控制车轮100转动时,可根据车轮100的转动信息驱动高于用于控车的方向盘的优先级的方向盘转动,以使高于用于控车的方向盘的优先级的方向盘与车轮100保持同步,或者,高于用于控车的方向盘的优先级的方向盘与车轮100可先不保持同步,而在高于用于控车的方向盘的优先级的方向盘需要接管控车时,再根据车轮100的转动信息驱动高于用于控车的方向盘的优先级的方向盘转动。此时,低于用于控车的方向盘的优先级的方向盘作为非待同步方向盘,非待同步方向盘与车轮100可不保持同步。
举例来说,当方向盘B为用于控车的方向盘时,由于方向盘A的优先级高于方向盘B的优先级,因此,方向盘A可作为待同步方向盘,即控制模块50在根据方向盘B的转动角度对车轮100进行控制时,还可控制方向盘A与车轮保持同步,或者,方向盘A与车轮100不保持同步,直至在需要方向盘A接管控车时,控制方向盘A与车轮100保持同步。 此时,方向盘C的优先级低于方向盘B的优先级,方向盘C可作为非待同步方向盘,方向盘C与车轮100可不保持同步。
另外,当M个方向盘10中存在默认方向盘时,可将高于用于控车的方向盘的优先级的方向盘和默认方向盘共同作为待同步方向盘。应理解,默认方向盘的优先级高于用于控车的方向盘的优先级时,高于用于控车的方向盘的优先级的方向盘即包括默认方向盘,而默认方向盘的优先级低于用于控车的方向盘的优先级时,除了将高于用于控车的方向盘的优先级的方向盘作为待同步方向盘以外,还将默认方向盘也作为待同步方向盘。
这样,控制模块50在根据用于控车的方向盘的转动信息控制车轮100转动时,可根据车轮100的转动信息驱动高于用于控车的方向盘的优先级的方向盘和默认方向盘转动,以使高于用于控车的方向盘的优先级的方向盘和默认方向盘与车轮100保持同步,或者,高于用于控车的方向盘的优先级的方向盘和默认方向盘与车轮100可先不保持同步,而在高于用于控车的方向盘的优先级的方向盘或默认方向盘需要接管控车时,再根据车轮100的转动信息驱动高于用于控车的方向盘的优先级的方向盘和默认方向盘转动。此时,低于用于控车的方向盘的优先级的方向盘(不包括默认方向盘)作为非待同步方向盘,非待同步方向盘与车轮100可不保持同步。
举例来说,当方向盘B为用于控车的方向盘时,由于方向盘A的优先级高于方向盘B的优先级,因此,方向盘A可作为待同步方向盘,同时,由于方向盘C为默认方向盘,因此,方向盘C也可作为待同步方向盘,即控制模块50在根据方向盘B的转动角度对车轮100进行控制时,还可控制方向盘A和方向盘C与车轮保持同步,或者,方向盘A和方向盘C与车轮100不保持同步,直至在需要方向盘A或方向盘C接管控车时,控制方向盘A和方向盘C与车轮100保持同步。
可以理解的是,当待同步方向盘与车轮100同步之后,可根据任一待同步方向盘的转动信息对转向机构40进行控制,以驱动车轮100转车。
根据本公开的一个实施例,除用于控车的方向盘以外的其他方向盘中非待同步方向盘与车轮100不保持同步。也就是说,控制模块50在根据用于控车的方向盘的转动信息对车轮100进行控制时,非待同步方向盘与车轮100不保持同步,即控制模块50不会根据车轮100的转动信息控制非待同步方向盘转动。此时,非同步方向盘可用于遥控控制。
控制模块50用于将M个方向盘中优先级低于用于控车的方向盘的优先级的方向盘作为非待同步方向盘;或者控制模块50用于将除默认方向盘以外的其他方向盘中,优先级低于用于控车的方向盘的优先级的方向盘作为非待同步方向盘。
也就是说,当M个方向盘10中不存在默认方向盘时,可将低于用于控车的方向盘的优先级的方向盘作为非待同步方向盘,这样,控制模块50在根据用于控车的方向盘的转动 信息控制车轮100转动时,可不根据车轮100的转动信息驱动低于用于控车的方向盘的优先级的方向盘转动,使得低于用于控车的方向盘的优先级的方向盘与车轮100不保持同步。
举例来说,当方向盘B为用于控车的方向盘时,方向盘C的优先级低于方向盘B的优先级,方向盘C可作为非待同步方向盘,方向盘C与车轮100可不保持同步。
另外,当M个方向盘10中存在默认方向盘时,可将除默认方向盘以外,低于用于控车的方向盘的优先级的方向盘作为非待同步方向盘。应理解,默认方向盘的优先级高于用于控车的方向盘的优先级时,低于用于控车的方向盘的优先级的方向盘即为非待同步方向盘,而默认方向盘的优先级低于用于控车的方向盘的优先级时,低于用于控车的方向盘的优先级的方向盘包括默认方向盘,可在低于用于控车的方向盘的优先级的方向盘中除去默认方向盘,并将除去默认方向盘后的低于用于控车的方向盘的优先级的方向盘作为非待同步方向盘。这样,控制模块50在根据用于控车的方向盘的转动信息控制车轮100转动时,可不根据车轮100的转动信息驱动低于用于控车的方向盘的优先级的方向盘(除去默认方向盘)转动,使得低于用于控车的方向盘的优先级的方向盘(除去默认方向盘)与车轮100不保持同步。
举例来说,当方向盘B为用于控车的方向盘时,由于方向盘C的优先级低于方向盘B的优先级,但由于方向盘C为默认方向盘,因此,方向盘C可作为待同步方向盘。假设车轮还设置有方向盘D,且方向盘D的优先级低于方向盘C的优先级,且方向盘D不是默认方向盘,此时,方向盘D可作为非待同步方向盘,方向盘D与车轮100可不保持同步。
可以理解的是,在车辆处于方向盘驾驶模式时,如果存在非待同步方向盘,可将非待同步方向盘用于遥控控制。
根据本公开的一个实施例,控制模块50例如转向控制器52进一步用于接收到任一非待同步方向盘的触发指令时,根据车轮100的转动信息对任一非待同步方向盘进行控制,以使任一非待同步方向盘与车轮100保持同步。并且,在任一非待同步方向盘与车轮100保持同步之后,根据任一非待同步方向盘的转动信息对转向机构40进行控制,以使转向机构40按照任一非待同步方向盘的转动信息驱动车辆的车轮100转动。
也就是说,当控制模块50在按照用于控车的方向盘即高优先级的方向盘的转动信息控制车辆时,如果非待同步方向盘即低优先级的方向盘要控制车辆,则可输入触发指令以触发任一低优先级的方向盘进入接管状态,此时,根据车轮100的转动信息对低优先级的方向盘进行控制,以使任一低优先级的方向盘与车轮100保持同步。并且,在任一低优先级的方向盘与车轮100保持同步之后,根据低优先级的方向盘的转动信息对转向机构40进行控制,以使车轮100响应低优先级的方向盘。
需要说明的是,在任一低优先级的方向盘与车轮100保持同步之后,还可在接收到另 一触发指令时,根据低优先级的方向盘的转动信息对转向机构40进行控制,以使车轮100响应低优先级的方向盘。
下面结合一个具体实施例来详细描述本公开实施例的M大于1时车辆的转向控制系统的控制方法。
根据本公开的一个实施例,当M>1时,控制模块50例如转向控制器52在车辆进入方向盘驾驶模式之后,先获取M个方向盘10的优先级顺序,然后判断默认方向盘的优先级是否为最高,如果默认方向盘的优先级为最高,则直接获取默认方向盘的转动信息,并根据默认方向盘的转动信息对转向机构40进行控制,以使车辆的车轮100与默认方向盘的转动同步。
默认方向盘例如主驾方向盘的优先级为最高时,直接根据默认方向盘的转动信息控制车轮,而除了默认方向盘以外的其他方向盘将不再进行车轮控制,例如可用于智能设备等的进行遥控控制。
举例来说,可以在主驾驶及副驾驶或其他位置各安装一个方向盘,可在主驾驶位置安装一个方向盘作为主驾方向盘,并可在副驾驶位置安装一个方向盘以作为副驾方向盘,并设置主驾方向盘和副驾方向盘的优先级。如图8所示,M个方向盘10包括主驾方向盘10-1和副驾方向盘10-2,M个方向盘转角传感器20可包括主驾方向盘转角传感器20-1和副驾方向盘转角传感器20-2,M个方向盘驱动单元30可包括主驾电机31-1以及副驾电机31-2,M个方向盘控制器51可包括主驾方向盘控制器51-1和副驾方向盘控制器51-2。其中,主驾方向盘控制器51-1通过主驾方向盘转角传感器20-1采集主驾方向盘10-1的转动角度和转动速度,以确定主驾驾驶人的转向意愿,并通过无线或无线方式发送给转向控制器52;主驾电机31-1可模拟转向力矩,以确保主驾方向盘10-1的转向舒适性;副驾方向盘控制器51-2通过副驾方向盘转角传感器20-2采集副驾方向盘10-2的转动角度和转动速度,以确定副驾驾驶人转向意愿,并通过有线或无线方式发送给转向控制器52;副驾电机31-2可模拟转向力矩,以确保副驾方向盘10-2的转向舒适性。
进而,转向控制器52通过采集主驾方向盘控制器51-1和副驾方向盘控制器51-2发送的转动角度和转动速度,并判断主驾方向盘10-1和副驾方向盘10-2的优先级,当主驾方向盘10-1的优先级高于副驾方向盘10-2的优先级时,转向控制器52根据主驾方向盘10-1的转动信息来带动转向机构40实现转向。另外,副驾方向盘可以控制其他智能设备。
由此,在默认方向盘优先级最高时,通过默认方向盘操作车辆方向,而其他方向盘不再操作车辆方向,从而确保车辆的驾驶安全性,同时兼备娱乐。并且,可以自由多个方向盘的优先级,提升用户的体验。
在本公开的一些实施例,控制模块50进一步用于在默认方向盘的优先级低于M个方 向盘10中至少一个方向盘的优先级时,确定M个方向盘10中被操作的至少一个方向盘,并根据被操作的至少一个方向盘中优先级最高的方向盘的转动信息对转向机构40进行控制,以使转向机构40按照被操作的至少一个方向盘中优先级最高的方向盘的转动信息驱动车辆的车轮100转动。
可以理解的是,方向盘10被操作可以指方向盘被驾驶员转动。
当M>1时,控制模块50例如转向控制器52在车辆进入方向盘驾驶模式之后,先获取M个方向盘10的优先级,然后判断默认方向盘的优先级是否为最高,如果默认方向盘的优先级非最高,即M个方向盘中至少存在一个方向盘的优先级高于(不包括等于)默认方向盘,那么,转向控制器52可实时采集M个方向盘的状态,当M个方向盘中只有一个方向盘10被操作时,转向控制器52可根据该方向盘10的转动信息来带动转向机构40以实现转向,当M个方向盘中有多个方向盘10被操作时,转向控制器52可确定多个方向盘10中优先级最高的方向盘,并根据多个方向盘10中优先级最高的方向盘的转动信息来带动转向机构40以实现转向。同时,在任一方向盘10被操作时该方向盘10所对应的方向盘驱动单元30可向相应的方向盘10施加转向力矩,以保证驾驶员手感舒适性。
在车辆处于方向盘驾驶模式且默认方向盘的优先级非最高时,可按照M个方向盘的优先级控制车辆的车轮100,不同优先级的方向盘同时有旋转动作时,优先级高的方向盘有优先控制权。
举例来说,当主驾驶位置为驾校学员或生手,而副驾驶位置为教练时,可设置副驾方向盘10-2的优先级最高,进而当主驾方向盘10-1被操作且副驾方向盘10-2未被操作时,转向控制器52可获取主驾方向盘10-1的转动角度和转动速度,并驱动转向机构40按照主驾方向盘10-1的转动角度和转动速度带动车轮100转向,当发现紧急状况而主驾驶位置人员不知如何处理或处理错误时,副驾驶教练可转动副驾方向盘10-2,此时,无论主驾方向盘10-1是否转动,转向控制器52均通过副驾方向盘控制器51-2获取副驾方向盘10-2的转动角度和转动速度,并驱动转向机构40按照副驾方向盘10-2的转动角度和转动速度带动车轮100转向,从而便于教练接替车辆驾驶权。
由此,多个方向盘可按照优先级控制车辆,提升驾驶安全性,便于进行驾驶教学。
在本公开的一些实施例,控制模块50进一步用于在被操作的至少一个方向盘中的优先级最高的方向盘与M个方向盘10中的优先级最高的方向盘不一致时,根据被操作的至少一个方向盘中优先级最高的方向盘的转动信息对M个方向盘10中优先级最高的方向盘进行控制,以驱动M个方向盘10中优先级最高的方向盘按照被操作的至少一个方向盘中优先级最高的方向盘的转动信息转动。
如果默认方向盘的优先级非最高,即M个方向盘中至少存在一个方向盘的优先级高于 (不包括等于)默认方向盘,那么,转向控制器52可实时采集M个方向盘的状态。当M个方向盘中只有一个方向盘10被操作时,转向控制器52可根据该方向盘10的转动信息来带动转向机构40以实现转向,同时判断该方向盘10是否为M个方向盘中的优先级最高的方向盘,如果不是,转向控制器52则将该方向盘10的转动信息发送给方向盘控制器51,方向盘控制器51可通过相应的方向盘驱动单元30并按照该转动信息对M个方向盘中优先级最高的方向盘进行控制,以使M个方向盘10中优先级最高的方向盘与该一个被操作的方向盘10同步转动。当M个方向盘中有多个方向盘10被操作时,转向控制器52可确定多个方向盘10中优先级最高的方向盘,并根据多个方向盘10中优先级最高的方向盘的转动信息来带动转向机构40以实现转向。同时,判断多个方向盘10中优先级最高的方向盘是否为M个方向盘中优先级最高的方向盘,如果不是,转向控制器52则将该多个方向盘10中优先级最高的方向盘的转动信息发送给方向盘控制器51,方向盘控制器51可通过相应的方向盘驱动单元30并按照该转动信息对M个方向盘中优先级最高的方向盘进行控制,以使M个方向盘10中优先级最高的方向盘与多个方向盘10中优先级最高的方向盘同步转动。
举例来说,假设主驾方向盘10-1的优先级低于副驾方向盘10-2的优先级,当主驾方向盘10-1被操作且副驾方向盘10-2未被操作时,转向控制器52可获取主驾方向盘10-1的转动角度和转动速度,并驱动转向机构40按照主驾方向盘10-1的转动角度和转动速度带动车轮100转向,同时,转向控制器52还可将主驾方向盘10-1的转动角度和转动速度发送给副驾方向盘控制器51-2,副驾方向盘控制器51-2可驱动副驾电机31-2,以控制副驾方向盘10-1按照主驾方向盘10-1的转动角度和转动速度转动,从而实现副驾方向盘10-2与主驾方向盘10-1的同步转动。
在本公开的一些实施例中,当M>1时,车载智能设备在监控到目标程序运行时,获取车辆的状态信息和方向盘信息,并在车辆处于方向盘驾驶模式或处于自动驾驶模式时,确定M个方向盘中的非待同步方向盘,并根据非待同步方向盘中至少一个方向盘的转动信息对目标对象进行控制。
可以理解的是,车辆的状态信息可包括车辆所处的驾驶模式,例如车辆是否处于方向盘驾驶模式,或者是否处于自动驾驶模式,或者是否处于停车状态等,方向盘信息可包括方向盘的转动信息、方向盘的使用情况以及方向盘的标志信息等。
需要说明的是,车载智能设备可一同获取车辆的状态信息和方向盘信息,或者,车载智能设备可依次获取车辆的状态信息和方向盘信息。并且,目标对象可以是虚拟对象例如车载智能设备上显示的虚拟方向盘、虚拟车辆,或者,目标对象可以是实体对象,例如车载智能设备自身,或车载智能设备的转动部件。
当M>1时,转向控制器52在车辆进入方向盘驾驶模式或进入自动驾驶模式之后,可判断M个方向盘是否存在非待同步方向盘,如果存在非待同步方向盘,则将非待同步方向盘中的至少一个用于遥控控制。
进而,当方向盘10为多个时,车载智能设备可根据用户的指令控制目标程序运行,并且,用户可在目标程序运行后操作方向盘。每个方向盘控制器51读取对应的方向盘10的转动角度和转动速度,并将对应的方向盘10的转动角度和转动速度发送到通信总线上。车载智能设备在监测到目标程序运行后,可直接通过车辆的通信总线读取信息,例如可通过通信总线读取车辆的状态信息和方向盘信息,并根据车辆的状态信息判断工作模式,即如果车辆处于方向盘驾驶模式或处于自动驾驶模式,则判断是否存在非待同步方向盘,如果存在非待同步方向盘,则从非待同步方向盘中选择出至少一个方向盘,并根据选择出的至少一个方向盘的转动信息对目标对象进行控制。如果不存在非待同步方向盘,则可不再根据M个方向盘10的转动信息对目标对象进行控制。
可以理解的是,车载智能设备在车辆处于方向盘驾驶模式或处于自动驾驶模式、且存在非待同步方向盘、且监测到目标程序运行时可显示提醒信息以提示用户操作方向盘。车载智能设备在车辆处于方向盘驾驶模式或处于自动驾驶模式、且未存在非待同步方向盘时可显示提醒信息以提示用户无法通过方向盘对目标对象进行控制。
举例来说,当M>1时,转向控制器52在车辆进入方向盘驾驶模式或处于自动驾驶模式之后,可判断默认方向盘的优先级是否为最高,如果默认方向盘的优先级为最高,则直接根据默认方向盘的转动信息对转向机构40进行控制。此时其他方向盘例如副驾方向盘10-2可用于遥控控制。
进而,当方向盘10为多个时,车载智能设备可根据用户的指令控制目标程序运行,并且,用户可在目标程序运行后操作方向盘。每个方向盘控制器51读取对应的方向盘10的转动角度和转动速度,并将对应的方向盘10的转动角度和转动速度发送到通信总线上。车载智能设备在监测到目标程序运行后,可直接通过车辆的通信总线读取信息,例如可通过通信总线读取车辆的状态信息和方向盘信息,并根据车辆的状态信息判断工作模式,即如果车辆处于方向盘驾驶模式或处于自动驾驶模式,则判断默认方向盘的优先级是否为最高,如果默认方向盘的优先级最高,则从默认方向盘以外的其他方向盘中选择出至少一个方向盘,并根据选择出的至少一个方向盘的转动信息对目标对象进行控制。如果默认方向盘的优先级并非是最高,则可不再根据M个方向盘10的转动信息对目标对象进行控制。
可以理解的是,车载智能设备在车辆处于方向盘驾驶模式或处于自动驾驶模式、且默认方向盘的优先级最高、且监测到目标程序运行时可显示提醒信息以提示用户操作方向盘。车载智能设备在车辆处于方向盘驾驶模式或处于自动驾驶模式、且默认方向盘的优先级非 最高时可显示提醒信息以提示用户无法通过方向盘对目标对象进行控制。
还需说明的是,用户可通过车载智能设备设置所需选择的方向盘,或者,车载智能设备可根据预设信息或实际需求设置所需选择的方向盘。例如车载智能设备可以根据模拟赛车游戏中赛车的数量及每个赛车对应方向盘的设置来确定所需选择的方向盘,即决定接收哪些方向盘的转动信息。
另外,在其他一些实施例中,车载智能设备还可对方向盘的使用状态进行判断,如果所需选择的方向盘处于使用中例如遥控其他设备,则可重新选择其他方向盘,或不再根据方向盘10的转动信息对目标对象进行控制,如果方向盘未处于使用中,则根据方向盘10的转动信息对目标对象进行控制。
在本公开一些实施例中,目标程序可为游戏程序例如模拟赛车游戏,目标对象可为游戏中的模拟对象,例如模拟赛车等。举例来说,当目标程序为模拟赛车游戏时,用户可触发模拟赛车游戏运行并对方向盘10进行操作,每个方向盘控制器51读取相应的方向盘10的转动角度和转动速度,并将相应的方向盘10的转动角度和转动速度发送到通信总线上。车载智能设备在车辆处于方向盘驾驶模式或处于自动驾驶模式、且默认方向盘的优先级最高且监测到目标程序运行后,可通过通信总线直接读取除默认方向盘以外的其他方向盘中至少一个方向盘的转动信息,并对该至少一个方向盘10的转动信息进行处理以对应生成至少一个目标对象的转动信息(包括转动角度、或转动速度、或转动角度和转动速度),然后根据至少一个目标对象的转动信息分别对对应的至少一个目标对象进行转向控制,例如模拟赛车游戏中的至少一个模拟赛车可分别根据对应的至少一个目标对象的转动角度和转动速度转动。
由此,在默认方向盘控制车辆时,其他方向盘可用于车载智能设备的遥控控制,在保证正常驾驶的同时兼顾乘客娱乐。
当M>1时,车载智能设备在监控到目标程序运行时,获取车辆的状态信息和方向盘信息,并在车辆未处于方向盘驾驶模式且未处于自动驾驶模式时,根据M个方向盘10中至少一个方向盘的转动信息对目标对象进行控制。
当M>1时,转向控制器52在车辆未进入方向盘驾驶模式且未处于自动驾驶模式时,例如处于停止状态时,车辆的车轮100可不随方向盘的转动而旋转,此时M个方向盘均可用于遥控控制。
进而,当方向盘10为多个时,车载智能设备可根据用户的指令控制目标程序运行,并且,用户可在目标程序运行后操作方向盘。每个方向盘控制器51读取对应的方向盘10的转动角度和转动速度,并将对应的方向盘10的转动角度和转动速度发送到通信总线上。车载智能设备在监测到目标程序运行后,可直接通过车辆的通信总线读取信息,例如可通过 通信总线读取车辆的状态信息和方向盘信息,并根据车辆的状态信息判断工作模式,即如果车辆未处于方向盘驾驶模式且未处于自动驾驶模式,则从M个方向盘中选择出至少一个方向盘,并根据选择出的至少一个方向盘的转动信息对目标对象进行控制。

由此,在车辆处于停止状态时,M个方向盘均可用于车载智能设备的遥控控制,在保证正常驾驶的同时兼顾乘客娱乐。
在本公开的其他实施例中,M>1时,控制模块50例如转向控制器52可在车辆处于自动驾驶模式时,不对M个方向盘10进行控制,即M个方向盘10与车轮100可不保持同步。此时,车载智能设备在确定M个方向盘中的非待同步方向盘之前只需判断车辆是否处于方向盘驾驶模式,即在所述车辆处于方向盘驾驶模式时,确定M个方向盘中的非待同步方向盘,并根据所述非待同步方向盘中至少一个方向盘的转动信息对目标对象进行控制,而在车辆未处于方向盘驾驶模式例如处于自动驾驶模式时,根据M个方向盘中至少一个方向盘的转动信息对目标对象进行控制。应理解,自动驾驶模式下,M个方向盘10与车轮100可不保持同步的时,车载智能设备在自动驾驶模式下的控制方式与前述实施例中车辆未处于方向盘驾驶模式且未处于自动驾驶模式时的控制方式基本一致,这里不再详细赘述。
根据本公开的另一些实施例,当M>1时,控制模块50例如转向控制器52可与移动智能设备进行无线通信,移动智能设备在监控到目标程序运行时向控制模块50发送请求指令,并接收控制模块50发送的车辆的状态信息和方向盘信息;移动智能设备在车辆处于方向盘驾驶模式或处于自动驾驶模式时,确定M个方向盘中非待同步方向盘,并根据非待同步方向盘中至少一个方向盘的转动信息对目标对象进行控制。
需要说明的是,移动智能设备可指并未安装在车辆上的智能设备。转向控制器52在接 收到请求指令之后可将车辆的状态信息和方向盘信息一同发送给移动智能设备,或者,转向控制器52将按照先后顺序依次将车辆的状态信息发送给移动智能设备。并且,目标对象可以是虚拟对象例如移动智能设备上显示的虚拟方向盘、虚拟车辆,或者,目标对象可以是实体对象,例如移动智能设备自身,或移动智能设备的转动部件。
当M>1时,转向控制器52在车辆进入方向盘驾驶模式或自动驾驶模式之后,可判断M个方向盘是否存在非待同步方向盘,如果存在非待同步方向盘,则将非待同步方向盘中的至少一个用于遥控控制。
进而,当方向盘10为多个时,移动智能设备可根据用户的指令控制目标程序运行,并且,用户可在目标程序运行后操作方向盘。每个方向盘控制器51读取对应的方向盘10的转动角度和转动速度,并将对应的方向盘10的转动角度和转动速度发送给转向控制器52。移动智能设备在监测到目标程序运行后,可向转向控制器52发送请求指令,转向控制器52在接收到请求指令之后向移动智能设备反馈信息。
例如转向控制器52在接收到请求指令之后可将车辆的状态信息和方向盘10的转动信息发送给移动智能设备,然后移动智能设备根据车辆的状态信息判断工作模式,即如果车辆处于方向盘驾驶模式或自动驾驶模式,则判断是否存在非待同步方向盘,如果存在非待同步方向盘,则从非待同步方向盘中选择出至少一个方向盘,并根据选择出的至少一个方向盘的转动信息对目标对象进行控制。如果不存在非待同步方向盘,则可不再根据M个方向盘10的转动信息对目标对象进行控制。
可以理解的是,移动智能设备在车辆处于方向盘驾驶模式或自动驾驶模式、且存在非待同步方向盘、且监测到目标程序运行时可显示提醒信息以提示用户操作方向盘。移动智能设备在车辆处于方向盘驾驶模式或自动驾驶模式、且未存在非待同步方向盘时可显示提醒信息以提示用户无法通过方向盘对目标对象进行控制。

还需说明的是,用户可通过移动智能设备设置所需选择的方向盘,或者,移动智能设备可根据预设信息或实际需求设置所需选择的方向盘。例如移动智能设备可以根据模拟赛车游戏中赛车的数量及每个赛车对应方向盘的设置来确定所需选择的方向盘,即决定选择哪些方向盘的转动信息。
另外,在其他一些实施例中,移动智能设备还可对方向盘的使用状态进行判断,如果所需选择的方向盘处于使用中例如遥控其他设备,则可重新选择其他方向盘,或不再根据方向盘10的转动信息对目标对象进行控制,如果方向盘未处于使用中,则根据方向盘10的转动信息对目标对象进行控制。
在本公开一些实施例中,目标程序可为游戏程序例如模拟赛车游戏,目标对象可为游戏中的模拟对象,例如模拟赛车等。或者,目标程序可为无人机遥控程序,目标对象可为无人机,无人机的转向机构可控制无人机转向。举例来说,当目标程序为至少一个无人机遥控程序时,用户可触发至少一个无人机遥控程序运行并对至少一个方向盘进行操作,M个方向盘控制器51分别读取对应的M个方向盘10的转动角度和转动速度,并将M个方向盘10的转动角度和转动速度发送给转向控制器52,转向控制器52将除默认方向盘以为的其他方向盘的转动角度和转动速度实时分别发送给每个无人机,每个无人机在车辆处于方向盘驾驶模式或自动驾驶模式、且默认方向盘的优先级最高且监测到目标程序运行后,从除默认方向盘以为的其他方向盘的转动角度和转动速度选择出一个方向盘,并对选择出的方向盘的转动信息进行处理以得到目标对象的转动信息(包括转动角度、或转动速度、或转动角度和转动速度),然后根据目标对象的转动信息对无人机进行转向控制,以对无人机进行遥控控制。

在本公开的其他实施例中,M>1时,控制模块50例如转向控制器52可在车辆处于自动驾驶模式时,不对M个方向盘10进行控制,即M个方向盘10与车轮100可不保持同步。此时,移动智能设备在确定M个方向盘中的非待同步方向盘之前只需判断车辆是否处于方向盘驾驶模式,即在所述车辆处于方向盘驾驶模式时,确定M个方向盘中的非待同步 方向盘,并根据所述非待同步方向盘中至少一个方向盘的转动信息对目标对象进行控制,而在车辆未处于方向盘驾驶模式例如处于自动驾驶模式时,根据M个方向盘中至少一个方向盘的转动信息对目标对象进行控制。应理解,自动驾驶模式下,M个方向盘10与车轮100可不保持同步的时,移动智能设备在自动驾驶模式下的控制方式与前述实施例中车辆未处于方向盘驾驶模式且未处于自动驾驶模式时的控制方式基本一致,这里不再详细赘述。
如上,当M>1时,本公开实施例的控制流程可如下:
对于车辆而言,在整车上电之后,转向控制器52判断车辆是否处于停止状态即未处于方向盘驾驶模式,如果处于停止,则车载智能终端可判断是否监测到目标程序运行,如果监测到目标程序,则读取副驾方向盘和主驾方向盘的转动角度和转动速度,并根据副驾方向盘和主驾方向盘中至少一个的转动角度和转动速度对至少一个目标对象进行控制移动智能设备移动智能设备移动智能设备。或者,移动智能终端可判断是否监测到目标程序运行,如果监测到目标程序,则向车辆发送请求指令,接收副驾方向盘和主驾方向盘的的转动角度和转动速度,并根据副驾方向盘和主驾方向盘的中至少一个的转动角度和转动速度对至少一个目标对象进行控制。
如果未处于停止状态,转向控制器52则在车辆处于方向盘驾驶状态时,读取设置的方向盘优先级,并判断主驾方向盘的优先级是否为最高,如果主驾方向盘的优先级最高,则转向控制器52读取主驾方向盘的转动角度和转动速度,并驱动转向机构40按照主驾方向盘的转动角度和转动速度转动车轮,同时主驾电机提供对应反向扭矩,保证用户手感舒适性。此时,车载智能终端可判断是否监测到目标程序运行,如果监测到目标程序,则读取副驾方向盘的转动角度和转动速度,并根据副驾方向盘的转动角度和转动速度对目标对象进行控制。或者,移动智能终端可判断是否监测到目标程序运行,如果监测到目标程序,则向车辆发送请求指令,接收副驾方向盘的转动角度和转动速度,并根据副驾方向盘方向盘的转动角度和转动速度对目标对象进行控制。
