Description

一种利用平衡车载物的方法和平衡车 【技术领域】
本发明涉及平衡车控制领域,更具体的说,涉及一种利用平衡车载物的方法和平衡车。
【背景技术】
电动平衡车,又叫体感车、思维车,其运作原理主要是建立在一种被称为“动态稳定”的基本原理上,利用车体内部的陀螺仪和加速度传感器,来检测车体姿态的变化,利用伺服控制系统,精确地驱动电机进行相应的调整,以保持系统的平衡。
现有的电动平衡车一般有两种,一种是车体上具有一个操作杆,使用者站在电动平衡车的脚踏平台上对操作杆进行操作,从而前进、后退及停止,这样的控制也称“手控”。另一种是车体由两部分组成,左部分和右部分之间通过转动机构实现相互转动,从而实现“脚控”。现有的平衡车都基于载人来设计的,并未考虑到载物的情况。
【发明内容】
本发明所要解决的技术问题是提供一种可以让平衡车载物的利用平衡车载物的方法和平衡车。
本发明的目的是通过以下技术方案来实现的:
根据本发明的一个方面,本发明公开了一种平衡车载物的方法,包括步骤:
获取控制信号进入载物模式;
平衡车在空载状态下启动自平衡;
在预设的时间后计算载物的重量;
根据测量的载物重量计算安全行驶速度;
启动平衡车运行。
进一步的,所述获取控制信号进入载物模式的步骤包括:
将平衡车跟移动智能终端配对;
接收移动智能终端的控制信号进入载物模式;
所述启动平衡车运行的步骤包括:
实时计算平衡车跟控制器的距离,控制平衡车跟控制器的距离保持在预设距离内;当检测到平衡车按安全行驶速度运行时,平衡车和控制器的距离仍然持续拉大,发出告警信息;
所述平衡车的最大运行速度小于等于安全行驶速度。
本技术方案独创跟随模式,通过蓝牙跟手机、手环等连接,人走动时平衡车跟随走动。无须复杂的路线规划、导航,且由于有人“带路”,运行可靠性更高,且可以适用于各种复杂的环境和路道,显著提高了平衡车载物的应用场景。
进一步的,所述利用平衡车载物的方法还包括预存路线信息的步骤,所述启动平衡车运行的步骤包括:控制平衡车按路线信息、以安全行驶速度匀速运行。
进一步的,所述预存路线信息的步骤还包括:
与移动智能终端建立通信连接;
存储移动智能终端发送的路线信息;
所述控制平衡车按路线信息、以安全行驶速度匀速运行的步骤包括:
基于导航系统控制平衡车按路线信息、以安全行驶速度匀速运行。
通过导航(GPS、北斗、伽利略等都可以)可以预先规划路线,让平衡车按预定路线行走。
进一步的,所述利用平衡车载物的方法还包括规避障碍物的步骤:
计算平衡车前方物体高度,将高度超过预设值的物体标记为障碍物;
测量障碍物宽度;
根据障碍物宽度和坐标位置规划行车路线;
标注障碍物坐标位置并更新到障碍物地图数据库;
与附近的平衡车联网共享障碍物地图数据库。
现有技术是被动式探测障碍物,要实时探测、计算,运算量大,算法复杂。本发明先通过判断物体高度,先排除一部分平衡车可以直接越过的物体,而对于平衡车无法越过的障碍物,本发明技术方案也仅计算物品的宽度,不需要构件障碍物的形状和尺寸,算法简单,运算量很小。再者,本发明可以将新发现的障碍物实时更新到障碍物地图,供自己和其他平衡车参考,随着数据的积累,判断障碍物和规划行车路线会越来越准确,具备自成长的能力,智能化程度更高,且避免了不必要的重复计算。
进一步的,所述根据障碍物宽度和坐标位置规划行车路线的步骤还包括:
拍摄障碍物的图片;
将图片上传到云端服务器进行识别;
根据识别结果修正行车路线。
有些物品,比如海绵、草堆,虽然比较高,但平衡车还是可能直接跨过去的。但同样高度的物品,如果换成是砖头,可能就得绕行了。
进一步的,所述根据障碍物宽度和坐标位置规划行车路线的步骤还包括:
访问通用地图数据库;
获取道路信息;
基于道路信息规划行车路线。
通用地图数据库是指百度地图、高德地图、腾讯地图等常用的地图,里面包含了各个道路的信息,因此平衡车可以在道路的限定条件下规划行车路线。传统的通用地图已经给出了道路的边界,即道路的边界等同于障碍物,但道路地图不可能把道路中存在的障碍物标示出来,因此两者结合,才能使行车路线更具有可操作性,安全程度更高。
进一步的,所述标注障碍物坐标位置并更新到障碍物地图数据库包括:
判断障碍物的运动状态;
仅将静止状态的障碍物更新到障碍物地图数据库。
动态障碍物随时移动,更新到地图没有实际意义。
进一步的,所述规避障碍物的方法还包括:
判断障碍物的运动状态;
当障碍物处于运动状态时,控制平衡车减速或暂停。
根据本发明的另一个方面,本发明公开了一种平衡车,包括:
用于获取控制信号进入载物模式的装置;
用于启动平衡车自平衡的装置;
用于在预设的时间后计算载物的重量的装置;
用于根据测量的载物重量计算安全行驶速度的装置;
用于启动平衡车运行的装置。
进一步的,所述用于获取控制信号进入载物模式的装置包括:
用于将平衡车跟移动智能终端配对的装置;
用于接收移动智能终端的控制信号进入载物模式的装置;
用于启动平衡车运行的装置包括:
用于实时计算平衡车跟控制器的距离,控制平衡车跟控制器的距离保持在预设距离内;当检测到平衡车按安全行驶速度运行时,平衡车和控制器的距离仍然持续拉大,发出告警信息的装置;
所述平衡车的最大运行速度小于等于安全行驶速度。
与现有技术相比,本发明的技术效果是:平衡车进入载物模式以后,在空载状态下启动自平衡,这样就可以在上面稳定地放置物品,等放置完毕后,计算载物的重量,根据重量来设置安全行驶速度,最后控制平衡车运行。一般来说,越重的物品惯性越大,安全行驶速度越低。采用本发明无须更改现有平衡车的电路和结构,就可以让平衡车能够安全、可靠地载物。

所述平衡车的最大运行速度小于等于安全行驶速度。
平衡车在载人的时候,只要踏板检测载重,就会启动运行,这种运行模式是无法进行载物的。而本发明的平衡车进入载物模式以后,在空载状态下启动自平衡,这样就可以在上面稳定地放置物品,等放置完毕后,计算载物的重量,根据重量来设置安全行驶速度,最后控制平衡车运行。一般来说,越重的物品惯性越大,安全行驶速度越低。采用本发明无须更改现有平衡车的电路和结构,就可以让平衡车能够安全、可靠地载物。
基于上述平衡车,本实施方式公开一种平衡车载物的方法,该方法可应用但不局限于本发明的平衡车。
该平衡车载物的方法包括步骤:
获取控制信号进入载物模式;
平衡车在空载状态下启动自平衡;
在预设的时间后计算载物的重量;
根据测量的载物重量计算安全行驶速度;
启动平衡车运行。
可选的,所述获取控制信号进入载物模式的步骤包括:
将平衡车跟移动智能终端配对;

所述平衡车的最大运行速度小于等于安全行驶速度。
本技术方案独创跟随模式,通过蓝牙跟手机、手环等连接,人走动时平衡车跟随走动。无须复杂的路线规划、导航,且由于有人“带路”,运行可靠性更高,且可以适用于各种复杂的环境和路道,显著提高了平衡车载物的应用场景。在此模式下,基本上驾驶人员操控平衡车可以运行的环境,载物状态下的平衡车都能适用,应用场景更宽泛。平衡车和控制器的实时测距有多种方式可以实现,以下以蓝牙测距进行举例说明。
蓝牙是一种电磁波的,所以可以使用电磁波原理测距。发射位置与接收位置的距离,可以中间有一个镜子进行反射的。根据发射时间与接收时间进行测距,当然,这种方法用不到电脑上的。且误差是+/-1M左右。按时间与传播的速度得出的。
另外一种方式,可以让蓝牙同时发身不同波长的波,接收后可以得到相应的处理,因为是同时发射击,而不同波在接收后查看其查关的相位。然后进行一些复杂的计算,如果其两个波长又时相位重合,则这个距离一定是波长最小公倍数的整数倍。波长越多越精确,类似激光测距仪的原理的,这样更精确。
