对于许多驾驶员而言,泊车是一种痛苦的经历,大城市停车空间有限,将车辆驶入狭小的空间已成为一项必备技能。然而很少有不费一番周折就停好车的情况。基于此,自动泊车技术应运而生。
现有的自动泊车技术,通常都是通过传感器来识别车位,然后根据建立的坐标系确定车辆与停车位之间的相对位置,结合车辆位姿和车位位姿进行连接路径计算,并结合周边环境、障碍物干涉检测,得出自动泊车的规划路径;在获取到车辆自动泊车的规划路径后,系统基于此路径来控制执行机构实现路径跟随,最终实现自动泊车。

具体实施方式
为使本发明的上述目的、特征和优点能够更加明显易懂,下面结合附图和具体实施方式对本发明作进一步详细的说明。
为了改变现有的泊车方式在规划路径不合理的情况下,重新规划路径的次数过多,泊车时间过长的问题。本发明提出了一种构思在于,通过检测用户的调整操作来生成调整指令,在泊车过程中调整规划路径,以优化规划路径,快速实现泊车。
如图1所示,本发明即是在车载系统中通过人机交互介质(如人机交互界面、软开关/硬开关)参与泊车控制环节,具体地,在本发明中,完成泊车控制需要以下模块协同作用,包括泊车系统控制单元,雷达,摄像头,电源模块,硬开关/软开关,关联系统(加速、转向、制动、档位等控制单元)等。其中,泊车系统控制单元用于协调控制各个模块;雷达和摄像头用于感知环境情况;电源模块用于提供能源;硬开关/软开关用于输入调整指令;人机交 互界面用于显示规划路径;关联系统用于控制车辆运动。通过多模块协调作用,即可实现在自动泊车过程中调整规划路径的效果。
以下通过具体实施例进行说明。
参照图2,示出了本发明的一种泊车的规划路径调整方法实施例的步骤流程图,所述方法应用于车载系统,所述车载系统具有显示界面,所述方法具体可以包括:
101,确定第一规划路径;
规划路径是指根据车辆与停车位之间的相对位置,结合车辆位姿和车位位姿计算得出的车辆进行泊车时所要行驶的路线。
在本发明实施例中,当车辆启动泊车功能时,可以确定车辆的第一规划路径。
具体地,当车辆启动泊车功能时,会通过传感器来识别车位,然后根据建立的坐标系确定车辆与车位的相对位置,结合车辆位姿和车位位姿进行连接路径计算,并结合周边环境、障碍物干涉检测,得出泊车的规划路径;该规划路径即为第一规划路径。
102,检测用户的调整操作;
当驾驶员发现车辆的第一规划路径规划不合理时,如发现因传感器存在盲区使得规划路径上存在障碍物,或者因为系统精度问题导致规划路径离障碍物过近。此时用户便可以进行调整操作,当检测到用户的调整操作时,便可根据调整操作对规划路径线进行调整。
103,根据所述调整操作,生成调整指令;
当检测到用户的调整操作时,可以根据调整操作生成调整指令。
104,根据所述调整指令调整所述第一规划路径,生成第二规划路径;
当确定了调整指令后,可以根据调整指令调整第一规划路径,生成第二规划路径。
例如,用户发现第一规划路径上存在障碍物,此时,通过调整操作向车载系统发出向右调整的指令,使规划路径可以向右偏移,避开障碍物。通过 调整后产生的规划路径即为第二规划路径。
105,按照所述第二规划路径进行泊车。
在确定第二规划路径后,可以按照第二规划路径进行泊车。
本发明实施例包括以下优点:本发明实施例可以通过确定第一规划路径;检测用户的调整操作;并根据检测到的调整操作,生成调整指令;根据调整指令调整第一规划路径,生成第二规划路径,从而可以按照第二规划路径进行泊车。在本发明实施例中,驾驶员可以以周边环境情况为依据,通过针对调整介质的调整操作,参与泊车规划路径的调整。从而增强了系统安全性,提高了泊车效率,优化了交互体验。
参照图3,示出了本发明的一种泊车的规划路径调整方法的另一种实施例的步骤流程图,所述方法应用于车载系统,所述车载系统具有显示界面,所述方法具体可以包括:
201,确定第一规划路径;
在本发明实施例中,当车辆启动泊车功能,可以确定第一规划路径。
具体地,当车辆启动泊车功能时,会通过传感器来识别车位,然后根据建立的坐标系确定车辆与车位的相对位置,结合车辆位姿和车位位姿进行连接路径计算,并结合周边环境、障碍物干涉检测,得出泊车的规划路径;该规划路径即为第一规划路径。
202,检测用户的调整操作;
当驾驶员发现车辆的第一规划路径规划不合理时,如发现因传感器存在盲区使得规划路径上存在障碍物,或者因为系统精度问题导致规划路径离障碍物过近。此时用户便可以进行调整操作;当检测到用户的调整操作时,便可根据调整操作对规划路径进行调整。
在一个示例中,当车辆泊车时,车辆的实时位姿在不断变化,传感器的盲区也会随之变化,当传感器检测到原本存在于盲区内的障碍物时,可以向用户发出警示;具体的,可以在人机界面上显示报警信息,也可以通过语音输出模块向用户发出语音提醒,从而提醒用户对泊车路径进行调整。
在一个示例中,还可以在人机界面上生成规避障碍物的建议路径,引导用户避开障碍物。建议路径可以为多条,用于尽量降低传感器盲区对规划路径的影响。用户可以通过直接选择建议路径的方式来改变泊车路径,也可以通过调整操作,使车辆的新的规划路径与建议路径重合,以按照建议路径进行泊车操作。
在一个示例中,车辆还可以通过服务器获取到其他车辆上传的于此处泊车的数据记录,通过分析数据记录得到当前位置的泊车出错率,并依据泊车出错率来提醒用户提高泊车过程中的注意力,在必要时调整泊车路径,以避免泊车失误。
又或者,通过服务器获取到其他车辆在此处泊车时的调整路径,从而筛选出较好的泊车路径推荐给用户,并在界面上进行显示,以供用户进行选择,进而根据所选择的路径进行泊车。
在本发明实施例中,所述车载系统包括调整介质,所述检测用户的调整操作可以包括:检测用户作用于调整介质的调整操作。
其中,调整介质可以包括物理接触作用介质和声音作用介质。物理接触作用介质可以包括人机界面上的软开关、面板上的物理开关、旋钮等。声音作用介质可以包括语音接收模块等。
具体地,用户作用于调整介质的调整操作可以包括对软开关的点击、长按或滑动等;对物理开关的按压、掰动等;也可以包括对旋钮的扭动;还可以包括对语音接收模块进行声音输入操作。
在一个示例中,以软开关为例,软开关可以包括“向左调整”和“向右调整”。用户的调整操作可以包括点击“向左调整”或点击“向右调整”。
在本发明实施例中,在检测用户的调整操作之前,还包括:检测用户的调整启动操作;响应所述调整启动操作,启动规划路径调整功能。
在实际应用中,可以在车载系统中设置调整功能启动介质,用以控制调整功能的启动与关闭。具体的,调整功能启动介质可以包括物理接触作用介质和声音作用介质。物理接触作用介质可以包括人机界面上的软开关、面板上的物理开关、旋钮等。声音作用介质可以包括语音接收模块等。
具体地,用户作用于调整介质的调整操作可以包括对软开关的点击、长按或滑动等;对物理开关的按压、掰动等;也可以包括对旋钮的扭动;还可以包括对语音接收模块进行声音输入操作。
在本发明实施例中,当检测到用户的调整启动操作时,便可启动规划路径调整功能。
如图4所示,在本发明实施例中,所述显示界面展示有调整功能图标,所述方法还可以包括:响应所述调整启动操作,点亮所述调整功能图标。
为了让用户能够知道所发出的调整启动操作是否得到响应,可以在显示界面上设置对应的调整功能图标,当调整启动操作得到响应时,点亮该调整功能图标,以告知用户操作已被执行。
203,确定所述调整操作的调整方向;
用户作用于调整介质上的调整操作可以根据调整介质的不同而不同。其中,用户作用于调整介质上的调整操作可以包括点击、长按、旋转、声控等。
当检测到用户的调整操作时,可以根据调整操作作用的介质确定调整方向。例如,当检测到用户的调整操作作用于软开关的“向左调整”时,可以确定调整方向为行进路线的左侧。
204,按照所述调整方向,生成方向调整指令;
当确定了规划路径的调整方向后,可以根据调整方向生成方向调整指令。
在一个示例中,当“向左调整”图标被点击,则意味着确定对规划路径的调整为向左调整,此时可以生成向左调整的指令,用以对规划路径进行向左的调整。
如图4所示,在本发明实施例中,所述显示界面上还展示有多个方向调整图标,所述方法还包括:响应所述调整指令,点亮相应的方向调整图标。
在本发明实施例中,方向调整图标可以包括“向左调整”图标和“向右调整”图标。
为了让用户能够知道所发出的调整操作是否得到响应,可以在显示界面上设置调整操作对应的方向调整图标,当调整操作得到响应时,点亮该方向 调整图标,用以告知用户操作已被执行。例如,当调整操作是向左调整时,在显示界面上对应点亮“向左调整”图标。
在本发明实施例中,所述根据所述调整操作生成调整指令还可以包括:
S11,确定所述调整操作的操作类型;
在本发明实施例中,操作类型还可以包括微调和快速调整。
在本发明实施例中,调整操作可以根据不同的调整介质而不同,其中,可以包括:点击、长按或旋转等。根据不同的操作确定不同的操作类型。
在一个示例中,针对于软开关,调整操作可以包括点击和长按,点击可以表示微调,长按可以表示快速调整。
在一个示例中,针对旋钮,调整操作可以为旋转操作。
S12,按照所述调整操作的操作类型,确定调整幅度。
当确定了操作类型后,便可以根据操作类型确定调整幅度。
在实际应用中,可以为不同的操作类型配置不同的调整幅度。
在一个示例中,针对软开关,当操作类型为微调时,规划路径做5度的微调,当操作类型为快速调整时,规划路径做15度的调整。此外,快速调整还可以根据长按的时间长度来设置相应的调整幅度。例如,长按2秒调整10度,长按3秒调整15度等。
在一个示例中,针对旋钮,不同的旋转角度可以代表不同的调整幅度。
在本发明实施例中,在确定了调整方向和调整幅度后,可以根据调整方向和调整幅度生成调整指令。
205,根据所述调整指令调整所述第一规划路径,生成第二规划路径;
当确定了调整指令后,可以根据调整指令调整第一规划路径,生成第二规划路径。
例如,用户发现第一规划路径上存在障碍物,此时,启动路径调整功能,通过长按向右调整功能图标,使规划路径向右偏移,避开障碍物。通过调整后产生的规划路径即为第二规划路径。
206,按照所述第二规划路径进行泊车。
在确定第二规划路径可以被执行时,可以按照第二规划路径进行泊车。
在本发明实施例中,在生成了第二规划路径后,还需要判断第二规划路径是否超出路径调整范围,在不超出路径调整范围的情况下才执行路径调整操作,在超出路径调整范围的情况下不执行路径调整操作。具体的,判断规划路径是否超出路径调整范围可以包括:
S21,获取车辆的当前姿态和方向盘转角参数,根据所述当前姿态和所述方向盘转角参数确定所述车辆的路径调整范围;
在实际应用中,车辆的路径调整范围可以通过车辆的当前姿态和方向盘转角参数确定。
车辆的当前姿态可以包括静止状态、加速状态、减速状态、左转状态、右转状态等,车辆的方向盘转角参数表征车轮相对于车身的角度关系。
在实际应用中,车辆的路径调整范围因车辆的当前姿态和方向盘转角参数的不同而有所差异。例如,在方向盘转角参数不变的情况下,加速状态的路径调整范围会小于静止状态下的路径调整范围。此外,路径调整范围的确定还与车辆本身性能有关。针对不同车辆的路径调整范围可以通过实验得出。
S22,判断所述第二规划路径是否处于所述路径调整范围之内;
当生成了第二规划路径后,需要判断第二规划路径是否处于路径调整范围之内。
在本发明实施例中,206可以包括:若所述第二规划路径处于所述路径调整范围之内,按照处于所述路径调整范围之内的第二规划路径进行泊车。
当第二规划路径处于路径调整范围之内时,则证明第二规划路径是可执行的,此时可以在显示界面上显示第二规划路径,并显示第二规划路径为可执行的第二规划路径,例如可以将第二规划路径显示为绿色。
若第二规划路径超出路径调整范围,证明第二规划路径是不合理的,无法被执行。此时显示第二规划路径为不可被执行的第二规划路径,例如可以将第二规划路径显示为红色,表示第二规划路径将不会被执行。
在本发明实施例中,在按照所述第二规划路径进行泊车时,若所述规划路径调整功能被关闭,则按照所述第一规划路径进行泊车。
在按照第二规划路径进行泊车的过程中,如果规划路径调整功能被关闭,则第二规划路径将无法被执行。为了保证泊车顺利进行,此时可以将规划路径切换为第一规划路径进行泊车。
如图5所示,在一个示例中,在车辆进入泊车(泊入或泊出)状态时,判断显示界面是否显示有第一规划路径,若有,判断第一规划路径是否合理(若显示界面没有显示第一规划路径,也可判断第一规划路径是否合理,只是可能出现滞后现象);若第一规划路径不合理;判断需要向左调整还是向右调整;若需要向左调整,则激活路径调整功能,点击向左调整;若需要向右调整,则激活路径调整功能,点击向右调整;判断显示界面上显示的调整后生成的第二规划路径是否合理;若合理,按照该第二规划路径进行泊车,直至下一次路径规划;若不合理,重新调整规划路径。
本发明实施例包括以下优点:本发明实施例通过确定第一规划路径;检测用户的调整操作;并根据检测到的调整操作,生成调整指令;根据调整指令调整第一规划路径,生成第二规划路径,从而可以按照第二规划路径进行泊车。在本发明实施例中,驾驶员可以以周边环境情况为依据,通过针对调整介质的调整操作,参与泊车规划路径的路线调整。从而增强了系统安全性,提高了泊车效率,优化了交互体验。
