101- a以滑动方式贯穿固定电磁铁 102-a和安装框架 103并伸出安装框架 103的 底侧 103-a外。 伸出端 101-a为本发明悬浮电磁力动力装置的动力引出端， 可直 接或间接作用在动力接受部， 或与机械设备的动力接受部连接。
需要说明的是， 二个电磁铁 102可以是二个吸盘式电磁铁， 也可以是一个 吸盘式电磁铁和一个铁磁体， 电磁铁和铁磁体在通电时能产生电磁力并相互吸 附， 实际使用中， 电磁铁和铁磁体的安装位置可以根据需要互换。 图示实施方 式中采用了二个相对设置的吸盘式电磁铁， 当二个电磁铁的电磁吸附面相对时， 电磁铁的电磁吸附力、 悬浮电磁力和吸附距离都以倍数增加。
吸盘式电磁铁的外形可以是圓盘形、 方盘形或条形， 其中央既可以设置贯 穿孔也可以不设置贯穿孔， 对应的动力引出轴的结构也有多种方式。 图示实施 方式中采用了二个中间设有贯穿孔的圓盘形电磁铁， 因此动力引出轴 101 的结 构比较筒单， 直接以一根圓柱贯穿二个电磁铁 102-a、 102-b和安装框架 103 , 其 中一端为定位端 101-b, 另一端为动力引出端 101-a。
可以理解的是， 动力引出轴 101的结构和功能包括： 1)与活动电磁铁 102-b 紧固并通过定位端 101-b带动活动电磁铁 102-b作往返运动； 2)通过伸出端 101-a 引出悬浮电磁力。
有必要对安装框架 103的结构和作用进行详细说明：贯穿二个电磁铁 102-a,
102- b的动力引出轴 101需要有安装载体， 安装框架 103可作为安装载体。 安装 框架 103的一侧固定一个电磁铁 102-a, 另一个电磁铁与动力引出轴 101紧固成 活动电磁铁 102-b, 活动电磁铁 102-b通过动力引出轴 101以滑动方式安装在安 装框架 103的另一侧。 活动电磁铁 102-b通过与固定电磁铁 102-a的位置关系， 实现在二个电磁铁之间产生悬浮电磁力、 引出悬浮电磁力、 维持悬浮电磁力， 或通过切断二个电磁铁的电源使悬浮电磁力消失以进入下一次工作循环。
安装框架 103可以是圓柱形、 方柱形、 框架形、 梯形、 槽形、 L型， 通过安 装框架 103把二个电磁铁安装成固定电磁铁 102-a和活动电磁铁 102-b
辅助动力结构 110可以是带动活动电磁铁 102-b在安装框架 103内作往返运 动的各种动力结构， 包括人工动力结构、 汽动力结构、 电机动力结构、 液压力 结构、 电磁吸附力结构、 弹簧力结构或反作用力结构。
在图示实施方式中， 辅助动力结构 110为小气缸 111 , 小气缸 111安装在安 装框架 103的顶侧 103-b上，小气缸 111的连接端 112与动力引出轴 101的定位 端 101-b连接， 小气缸 111可带动活动电磁铁 102-b在安装框架 103内作往返运 动。
电源控制结构 120可安装在安装框架 103上或安装在其他的适当位置， 电 源控制结构 120与固定电磁铁 102-a, 活动电磁铁 102-b和辅助动力结构 110的 小气缸 111电性连接； 电源控制结构 120包括电磁铁电源、 辅助动力结构电源、 电源控制电路、 密码电路、 遥控电路、 电流量调控显示电路以及自动开关、 遥 控开关或各种相应的控制开关。当小气缸 111带动活动电磁铁 102-b在安装框架 103内作往返运动时，电源控制结构 120为产生和引出悬浮电磁力提供协调的电 源通断和电流量大小调节， 以实现悬浮电磁力的有无和大小调节。
为了增加对悬浮电磁力的理解， 进一步揭示悬浮电磁力大小与作用距离的 关系， 本申请的发明人对本发明悬浮电磁力动力装置进行了测试， 其中， 二个 电磁铁应用了广东中山兰达电磁铁有限公司生产的吸盘式电磁铁 (型号 16050、 功率 45W、 电磁吸附力 4000N), 拉力测试仪为深圳市新三思材料检测有限公司 生产的微机控制电子万能试验机 (型号 CN76104)。
检测方法： 在悬浮电磁力动力装置的动力引出端垫上不导磁不锈钢片， 首 先， 当二个相对设置的电磁铁为相互吸附状态的零距离时， 不锈钢片与动力引 出端相互接触， 此时可检测到不锈钢片的抗拉力为零； 然后， 通过改变不锈钢 的厚度并持续对相对设置的电磁铁通电， 以不锈钢片的厚度为悬浮电磁力的作 用距离， 用拉力测量仪检测活动电磁铁的抗拉力， 以其抗拉力的最大峰值为悬 浮电磁力的作用力， 检测结果记录如下：
Figure imgf000011_0001
根据上述测试结果， 虽然应用了二个大功率的相对设置的电磁铁， 能检测 到悬浮电磁力的实际距离 L还是很短，一般不超过 10mm, 而具有实际使用价值 的距离 (称之为有效吸附距离) L1更短， 一般不超过 5mm。 从上述结果可知， 悬 浮电磁力的大小与吸附距离成反比关系， 即距离越小悬浮电磁力越大。 但在距 离为零时， 动力引出端的作用力被固定电磁铁阻挡， 故悬浮作用力为零， 这对 如何应用悬浮电磁力具有指导性意义： 即设置悬浮电磁力的有效吸附距离 L1必 须大于零， 一般而言应小于 5mm, 以数学方式表示： 0 < Ll 5mm。
当有效吸附距离 L1为零或小于零时， 固定电磁铁与活动电磁铁之间的悬浮 电磁力转化为接触的电磁吸附力， 此时， 动力引出端的力等于零， 接触的电磁 吸附力没有利用价值； 当有效吸附距离 L1大于 5mm时， 悬浮电磁力的实际使 用效果不理想， 此为本发明有別于现有技术的重要特征之一。
图 1所示实施方式的工作过程如下： 工作开始， 接通小气缸 111 电源的同 时断开二个电磁铁 l02-a、 102-b的电源， 小气缸 111带动活动电磁铁 102-b上升 到安装框架 103 的高点， 此时， 断开小气缸 111 的电源并同时接通二个电磁铁 102-a、 102-b的电源，活动电磁铁 102-b连同动力引出轴 101向固定电磁铁 102-a 运动， 当运动到二个电磁铁 102-a、 102-b的有效吸附距离时，二个电磁铁 102-a、 102-b产生强大的悬浮电磁力， 并通过动力引出端 101-a直接或间接作用在动力 接受部； 随之， 接通小气缸 111的电源， 断开二个电磁铁 102-a、 102-b的电源， 小气缸 111带动活动电磁铁 102-b上升，悬浮电磁力动力装置进入下一次工作循 环。
图 1 所示实施方式采用汽缸连接汽动力辅助动力结构， 适用于以大压力小 行程的各种机械设备， 即适用于功率较大的二个电磁铁和在安装框架内作较长 行程往返运动的悬浮电磁力动力装置， 可用于电阻焊设备上作为动力源。 如果 功率较小的二个电磁铁且在安装框架作往返运动的行程小于 50mm,本发明提出 图 2所示的悬浮电磁力动力装置。
图 2所示的悬浮电磁力动力装置包括一体化电磁铁结构 100、辅助动力结构 110和电源控制结构 120, —体化电磁铁结构 100包括动力引出轴 101、 二个电 磁铁 102和安装框架 103 , 二个电磁铁 102中的一个电磁铁固设在安装框架 103 底侧 103-a上形成固定电磁铁 102-a, 另一个电磁铁与动力引出轴 101紧固形成 活动电磁铁 102-b, 动力引出轴 101贯穿固定电磁铁 102-a和活动电磁铁 102-b„ 动力引出轴 101的两端分別为伸出端 101-a和定位端 101-b, 定位端 101-b以滑 动方式安装在安装框架 103的顶侧 103-b上，伸出端 101-a以滑动方式贯穿固定 电磁铁 102-a和安装框架 103并伸出安装框架 103的底侧 103-a外。伸出端 101-a 为本发明悬浮电磁力动力装置的动力引出端， 可直接或间接作用在动力接受部， 或与机械设备的动力接受部连接。
图 2所示悬浮电磁力动力装置中的辅助动力结构 110为另一个电磁铁 111 , 电磁铁 111的结构为电磁铁线圏 112-a、 线圏 112-b和活动铁芯 113; 电磁铁 111 的工作过程如下： 在对线圏 112-a通电时线圏 112-b处于断电状态， 此时可对活 动铁芯 113回拉； 在对线圏 112-a断电的同时， 接通线圏 112-b的电流， 此时可 使活动铁芯 113外推。电磁铁 111安装在安装框架 103的顶端 103-b,使线圏 112-a 处在活动电磁铁的远端， 线圏 112-b处在活动电磁铁的近端， 活动铁芯 113则与 动力引出轴 101的定位端 101-b连接。
电源控制结构 120分別与一体化电磁铁结构 100的二个电磁铁 102-a、 102-b 和辅助动力结构 110的另一电磁铁 111电性连接和设置开关 121 ,或者还设置密 码电路、 遥控电路和遥控开关 122。
工作开始，开关 121或遥控开关 122接通电磁铁线圏 112-a电源的同时断开 电磁铁线圏 112-b和二个电磁铁 102-a、 102-b的电源， 电磁铁 111产生电磁吸附 力， 把活动铁芯 113回拉， 同时带动活动电磁铁 102-b向电磁铁 111方向运动； 随之，断开电磁铁线圏 112-a的电源，并同时接通线圏 112-b和二个电磁铁 102-a、 102-b的电源， 活动铁芯 113推动活动电磁铁 102-b向固定电磁铁 102-a方向运 动， 当运动到二个电磁铁 102的有效吸附距离时， 二个电磁铁 102-a、 102-b产 生悬浮电磁力，并通过动力引出轴 101的伸出端 101-a直接或间接作用在动力接 受部；随之，接通电磁铁线圏 112-a的电源，断开线圏 112-b和二个电磁铁 102-a, 102-b的电源， 悬浮电磁力动力装置进入下一次工作循环。
图 2所示的悬浮电磁力动力装置的二个电磁铁功率较小， 且在安装框架作 往返运动的行程较小， 可以安装在枪弹击发装置上作动力源， 也可以在电阻焊 显微焊接上作动力源。
因为悬浮电磁力动力装置具有由电信号控制、 响应极其迅速和作用力行程 短的特点，所以可应用于电阻焊设备上 (图 3),枪弹击发装置上 (图 4)和机动车智 能紧急掣动系统中（图 5)。
下面结合图 3 ,进一步说明采用本发明悬浮电磁力动力装置作为电阻焊点焊 机的动力源的实施方式的结构、 工作过程和原理。
请参阅图 3所示，电阻焊点焊机 300包括机身 301、上电极 302、下电极 303、 被焊件 304、 阻焊变压器 305、 上电极夹头 306和电极夹头轴 307。
上电极 302和下电极 303分別与阻焊变压器 305连接， 作为加压机构的动 力接受部的电极夹头轴 307设于上电极夹头 306上， 电极夹头轴 307与悬浮电 磁力动力装置的动力引出端 (即伸出端 101-a)连接， 为电阻焊点焊提供焊接力。 悬浮电磁动力装置作为加压机构安装在机身 301 的顶框， 即原加压机构汽缸的 安装位置上， 悬浮电磁力动力装置完全取代原先的空气压缩机和汽缸。
在图 3所示的实施方式中：悬浮电磁力动力装置的固定电磁铁 102-a和活动 电磁铁 102-b为二个 180x50mm、功率 45W的圓柱形吸盘式相向电磁铁， 电源 控制结构 120分別与固定电磁铁 102-a, 活动电磁铁 102-b电性连接； 贯穿固定 电磁铁 102-a和活动电磁铁 102-b的动力引出轴 101的规格为 Φ15ηιηι; 辅助动 力结构 110为小汽缸 111 , 小汽缸 111的活动轴 112与动力引出轴 101的定位端 101-b连接， 为活动电磁铁 102-b在安装框架 103内作往返活动提供动力。
因为悬浮电磁力的有效吸附距离 L1很小，所以本实施方式把二个电极 202、 203 和焊件 204之间的距离设置在零距离， 二个相向电磁铁吸附面之间的距离 L1设置在 0 < LI 5mm, 以保证电极力的足够行程和取得令人满意的电极力。 通过测量， 在上述距离范围内， 本实施方式利用悬浮电磁力可获得最大 6000N 的电极力。 因此， 作为动力源， 本发明悬浮电磁力动力装置完全可以取代传统 电阻焊设备中粗大笨重的空气压缩机。
辅助动力结构 110的小汽缸 111的作用是带动活动电磁铁 102-b在安装框架 103内作往返运动， 本实施方式中活动电磁铁 102-b的重量约 5公斤， 现有技术 要获得 6000N的电极力必须要配备粗大的空气压缩机， 因此， 本实施方式中的 辅助动力结构显然要小巧得多。
在图 3实施方式中， 电源控制结构 120与悬浮电磁力动力装置的固定电磁 铁 102-a、活动电磁铁 102-b和辅助动力小气缸 111电性连接，电源控制结构 120 包括电源接通和延时断开电源的电路。当小气缸 111带动活动电磁铁 102-b上升 至最高端或最远端时，触发接通电磁铁电源； 当活动电磁铁 102-b下降至最低端 或最靠近固定电磁铁 102-a时， 电源控制电路提供一个断开电源的延时电讯号， 延迟电讯号一方面维持悬浮电磁力的作用时间， 另一方面又不影响活动电磁铁 102-b进入下一个工作循环。 电源控制结构 120的电流量调控显示电路则对电磁 铁的电流量进行调节和显示， 从而间接调节悬浮电磁力的大小， 满足机械设备 对动力的大小不同的要求。
在操作图 3 所示的电阻焊点焊机进行焊接前， 首先要调节好悬浮电磁力的 吸附距离 L1 , 具体方法为： 首先把电极 302、 303和焊件 304之间的距离调节到 相互接触的零距离， 然后将固定电磁铁 102-a和活动电磁铁 102-b之间的距离 L 调节到约 3mm, 如此， 就能保证焊接时悬浮电磁力处于有效吸附距离 L1内， 为 焊接提供足够大的电极力。
焊接开始前， 固定电磁铁 102-a和活动电磁铁 102-b的电源处于断开状态， 小汽缸 111带动活动电磁铁 102-b向上运动至安装框架 103的最高或最远端；焊 接开始，电源控制结构 120将电磁铁电源接通，小汽缸 111带动活动电磁铁 102-b 向下运动； 当活动电磁铁 102-b下降至悬浮电磁力的有效吸附距离 L1时， 固定 电磁铁 102-a和活动电磁铁 102-b之间产生强大悬浮电磁力， 动力引出端 101通 过动力接受部 电极夹头轴 307把悬浮电磁力传递到上电极 302, 为电阻焊的焊 接提供足够大的电极力， 使焊接顺利完成； 随后， 电源控制结构 120 自动将固 定电磁铁 102-a和活动电磁铁 102-b的电源断开， 小汽缸 111 带动活动电磁铁 102-b上升至安装框架 103的最高点，悬浮电磁力动力装置进入下一个工作循环。
可以理解的是， 以相同的方式， 本发明悬浮电磁力动力装置也可以安装在 电阻焊设备的缝焊机上， 此时， 悬浮电磁力动力装置的动力引出端与缝焊机加 压机构的动力接受部连接， 即可为电阻焊缝焊提供电极力。 此外， 本发明悬浮 电磁力动力装置还可以安装在电阻焊设备的对焊机上， 此时， 悬浮电磁力动力 装置的动力引出端与对焊机送进机构的动力接受部连接， 即可为电阻焊对焊提 供顶锻力。
在实际应用时， 根据需要加大二个相对设置的电磁铁就可以产生数千、 数 万牛顿的悬浮电磁力， 相对于传统电阻焊设备中粗重的高压空气压缩机， 本发 明只需配合 4艮小的辅助动力就可以得到足够大的电极力。 经测试， 本发明悬浮 电磁力动力装置不仅加压平稳， 而且能量转换率可达 80%以上， 远高于空气压 缩机不到 30%的能量转换率。
以下结合图 4,进一步说明采用本发明悬浮电磁力动力装置作为枪弹击发装 置的撞击动力的实施方式的结构、 工作过程和原理。
图 4所示枪弹击发装置包括： 枪膛 401、 子弹 402、 弹壳 403 , 弹壳 403外 圏上设有弹壳 槽 404, 弹壳 403后端面上有引信 槽 405 , 引信 槽 405作为 枪弹击发装置的动力接受部。 悬浮电磁力动力装置 100安装在枪膛 401的后面， 悬浮电磁力动力装置的动力引出端（即伸出端 101-a)的顶端加工成与引信凹槽 405适配的柱形的撞针， 动力引出端伸出端 101 -a与引信凹槽 405安装在同一轴 线上， 在安装框架 103的顶端 103-b固定安装有另一个电磁铁 111。 电磁铁 111 包括电磁铁线圏 112-a、线圏 112-b和活动铁芯 113 ,活动铁芯 113与定位端 101-b 连接。
本实施方式枪弹击发装置在开始工作前， 二个电磁铁 102处于靠近悬浮电 磁力的有效吸附距离的范围。 需要击发时， 电源控制结构 120接通电磁铁线圏 112-a的电源并同时断开线圏 112-b和二个电磁铁 102的电源， 电磁铁 111产生 电磁吸附力把活动电磁铁 102-b拉向安装框架顶端 103-b; 随之，断开线圏 112-a 的电源并同时接通线圏 112-b和二个电磁铁 102的电源，活动铁芯 113推动活动 电磁铁 112-b向固定电磁铁 102-a方向运动， 当达到悬浮电磁力的有效作用距离 L1 , 悬浮电磁力带动活动电磁铁 102-b和动力引出端 101-a的撞针， 快速撞击动 力接受部引信 槽 405 , 子弹 402被击发； 随之， 再断开线圏 112-b和二个电磁 铁 102-a、 102-b的电源而接通电磁铁线圏 112-a的电源， 悬浮电磁力随之消失， 活动电磁铁 102-b迅速复位， 枪弹击发装置进入下一次工作循环。
本实施方式枪弹击发装置的电磁铁只需要 4艮小的功率， 以设定电压为 12V、 功率为 2W 的电磁铁完全满足使用要求， 由于枪弹击发的时间很短， 一般只有 0.1秒左右，如果采用 lOOOOmAh的高容量充电电池，每充电一次就能实现约 200 万次的击发。 因此， 本实施方式枪弹击发装置的电源只需采用高容量的充电电 池， 无需以电源线外接电源。
现有技术枪弹击发通过弹簧板机的机械开关， 每个人都可以随意使用。 而 图 4所示实施方式悬浮电磁力动力装置枪弹击发的开关以电讯号控制， 就完全 可以设计出各种控制方式的击发开关， 包括可以设置通过密码电路控制的击发 开关， 实现枪支只能专人使用， 避免随意和滥用枪支， 对管控枪支的安全使用 具有重要意义。
由于本申请的发明人无法真正实施枪弹击发装置， 且枪弹击发还有很多复 杂的条件和环境， 但起码本发明可以作为现有技术的补充。 结合使用枪弹击发 产生的反作用力作辅助动力、 结合使用弹簧力作辅助动力， 可以设计出比现有 的枪支击发装置更完美、 更安全的新的枪弹击发装置。
以下结合图 5 ,进一步说明应用本发明悬浮电磁力动力装置的机动车智能紧 急掣动系统的实施方式的结构、 工作过程和原理。
本发明提出机动车智能紧急掣动系统是指机动车在行驶中即将撞上危险障 碍物时的霎间， 机动车能实现紧急自动掣动， 避免撞上障碍物的掣动系统。 本 发明机动车智能紧急掣动系统包括： 安装在车辆上的车速监测装置、 遥感测距 装置、 悬浮电磁力动力装置和智能控制装置， 智能紧急掣动系统的上述四部份 装置的电讯号相互连接、 协同作用， 可实现对车辆的智能紧急掣动。 可以理解 的是， 智能紧急掣动系统可以独立于正常行驶时用于减速、 停车的原有的掣动 系统。
机动车智能紧急掣动系统的结构如图 5 所示， 机动车智能紧急掣动系统包 括： 安装在车辆上的车速监测装置 501、 遥感测距装置 502、 悬浮电磁力动力装 置 503和智能控制装置 504,悬浮电磁力动力装置 503安装在邻近车辆传动结构 505的合适位置 511处，悬浮电磁力动力装置的动力引出端 506上安装有刹车闸 瓦片 507,刹车闸瓦片 507相应的位置为车辆传动结构 505的车轴 508,车轴 508 相应的表面加工有凹凸槽纹， 用以刹车闸瓦片 507掣动时加大掣动摩擦力， 悬 浮电磁力动力装置 503还包括电源控制结构 509和辅助动力结构 510,其具体结 构可以参照图 1和图 2所示的悬浮电磁力动力装置， 不再赘述。
机动车智能紧急掣动系统的工作过程包括： 车辆正常行驶， 车速监测装置 501检测车速， 当检测的车速达到预设定速度 (如 80公里 /小时)通过智能控制装 置接通遥感测距装置 502, 车辆正常行驶状态时， 刹车闸瓦片 507与车轴 508处 于分离状态， 当遥感测距装置 502检测到前方障碍物在预设定的危险距离 (如 5 米)通过智能控制装置接通悬浮电磁力动力装置 503 , 随着悬浮电磁力的产生和 引出， 动力引出端 506迅速带动刹车闸瓦片 507对车轴 508加压， 实现瞬间掣 动车辆， 车辆被完全掣动车速为零时。 通过智能控制装置 504松开悬浮电磁力 动力装置的刹车闸瓦片 507, 刹车闸瓦片 507与车轴 508回复到分离状态， 车辆 回复到可正常行驶状态。
图 5所示的机动车智能紧急掣动系统的工作原理包括： 一是现有技术的车 速检测装置、 遥感测距装置和智能控制装置都是以电讯号显示和控制， 而本发 明的悬浮电磁力动力装置也是以电讯号控制， 因此车速检测装置、 遥感测距装 置、 智能控制装置和悬浮电磁力的动力装置四部分就很容易通过相互自动连接， 实现智能控制紧急掣动的协同作用； 二是悬浮电磁力的响应极其迅速， 以刹车 闸瓦片与车轴距离为 10毫米， 悬浮电磁力动力装置完全可以在 10毫秒内以强 大而持久的悬浮电磁力作用在车轴上实现自动掣动，而按车速 80公里 /小时撞上 5米外的障碍物， 约需 220毫秒， 故以悬浮电磁力动力装置能实现及时对车辆的 自动紧急掣动， 为车辆的安全行驶智能紧急掣动提供了一种新的途径。
需要说明的是， 只要对机动车智能紧急掣动系统中的悬浮电磁力动力装置 503另外设置一个手控电源开关，悬浮电磁力动力装置 503也能独立进行手控紧 急掣动和复位。 还需要说明的是， 现有技术已提供有车辆向后行驶的倒车遥感测距装置， 由于车辆向后行驶的车速很慢， 机动车智能紧急掣动系统就很容易实现包括倒 车智能紧急掣动。 换言之， 机动车智能紧急掣动系统包括机动车向前行驶时的 智能紧急掣动系统和机动车向后行驶时的倒车智能紧急掣动系统。
倒车智能紧急掣动系统包括安装在车辆上的车速监测装置、 遥感测距装置、 悬浮电磁力动力装置和智能控制装置。 由于车辆行驶的方向不同， 只需要设置 另一个遥感测距装置。
倒车智能紧急掣动系统的工作过程如下： 当遥感测距装置在车辆向后行驶 时， 当检测到障碍物与车尾的预设定距离 (如 0.3米)， 通过智能监测装置同时接 通悬浮电磁力动力装置， 实现对倒车的智能紧急掣动； 车辆完全掣动后， 车速 监测装置监测到车速为零时， 通过智能控制装置松开悬浮电磁力动力装置的刹 车闸瓦片， 车辆回复到可正常行驶状态。 倒车智能紧急掣动系统的其它结构、 工作过程和作用原理都与车辆向前行驶的机动车智能紧急掣动系统相同， 不再 赘述。
在对机动车智能紧急掣动系统的结构、 工作过程和工作原理说明后， 需要 对智能控制装置作进一步介绍。 很明显， 机动车智能紧急掣动系统中的车速监 测装置、 遥感测距装置和悬浮电磁力动力装置所产生的各种讯息， 以电讯号的 形式经智能控制装置收集处理再以电讯号的形式发出执行指令。 换言之， 智能 控制装置也就是软件控制装置， 硬件部分包括车速监测及其车速预设定装置， 遥感测距及其预设定 (障碍物)距离装置， 悬浮电磁力动力装置， 软件控制的程序 至少包括：
一、 机动车向前行驶控制程序
1、 收集车速监测装置设置对车速预设定的电讯号， 当车速达到预定值时， 对遥感测距装置发出开始工作指令； 当收集到车速低于预设定值时， 对遥感测 距装置发出停止工作指令。 2、 收集遥感测距装置对障碍物距离预设定的电讯号， 当测距障碍物在预设 定值时， 对悬浮电磁力动力装置发出开始工作指令。
3、 收集车速监测装置的车速讯号， 当车速为零时， 对悬浮电磁力动力装置 发出停止工作指令。
二、 机动车向后行驶的倒车控制程序
