[0053] 在本实施例中, 加速踏板位置传感器 1的加速踏板位置电压信号 Ua实吋输入油 门位置智能控制器 4。 加速踏板位置传感器的输出 Ua代表了司机对油门的操作力 度, 通常, 电压 Ua越大表示司机的踩油门的力度越大, 也反映了司机的加速意 愿越强烈。
[0054] 在本实施例中, 在收到指令接收器 6的指令后, 防止驾驶员打瞌睡模块 5采集测 速模块 3中车辆的实吋行驶速度, 并与低速且安全行驶条件下的车速相比较, 确 定能够安全行驶的目标车速, 与油门位置智能控制器 4进行实吋数据通讯, 通过 油门位置智能控制器 4的降低控制后信号输出 Va, 进而改变输入发动机控制模块 2的电压信号, 进而降低发动机转速, 使车辆逐渐减速。
[0055] 【实施例 6】
[0056] 如图 6所示, 一种防止驾驶员打瞌睡的系统, 包括具有按钮的按钮装置、 加速 踏板位置传感器 1、 发动机控制模块 2、 测速模块 3、 油门位置智能控制器 4、 防 止驾驶员打瞌睡模块 5和指令接收器 6, 加速踏板位置传感器 1、 油门位置智能控 制器 4和发动机控制模块 2顺次相联, 组成串联电路。
[0057] 在本实施例中, 加速踏板位置传感器 1的加速踏板位置电压信号 Ual和 Ua2实吋 输入油门位置智能控制器 4。 加速踏板位置传感器的输出 Ual和 Ua2代表了司机对 油门的操作力度, 通常, 电压 Ual和 Ua2越大表示司机的踩油门的力度越大, 也 反映了司机的加速意愿越强烈。
[0058] 在本实施例中, 在收到指令接收器 6的指令后, 防止驾驶员打瞌睡模块 5采集测 速模块 3中车辆的实吋行驶速度, 并与低速且安全行驶条件下的车速相比较, 确 定防止能够安全行驶的目标车速, 与油门位置智能控制器 4进行实吋数据通讯, 通过油门位置智能控制器 4降低控制后信号输出 Val和 Va2, 进而改变输入发动机 控制模块 2的电压信号, 进而降低发动机转速, 使车辆逐渐减速。
[0059] 对于防止驾驶员打瞌睡的系统, 可以包括具有按钮的按钮装置和机动车车速控 制模块。 在第一规定吋间未按压按钮吋, 进行声光警示; 在第二规定吋间仍未 按压按钮吋, 则通过机动车车速控制模块使机动车减速或者停车。 按钮装置的 按钮可以仅是现有的具有物理结构的按钮, 该装置还可以包括声光警示模块和 能够收发指令的控制器。 按钮装置还可以是在现有物理按钮上集成声光警示功 能和指令收发功能的智能按钮。 机动车车速控制模块可以包括上述加速踏板位 置传感器、 油门位置智能控制器、 发动机控制模块、 防止打瞌睡模块、 指令接 收器和测速模块等。
[0060] 对于防止驾驶员打瞌睡的系统, 按钮模块可以与油门位置智能控制器信号相连 。 如在第二规定吋间仍未按压按钮, 则在按钮模块进行声光警示的同吋, 通过 油门位置智能控制器来调节发动机控制模块的输入电压 (通常是降低该输入电 压, 特定情况下可以提高该输入电压) , 使该输入电压保持在能够满足安全行 驶条件的控制电压范围内。
[0061] 对于防止驾驶员打瞌睡的系统, 声光警示吋, 发动机依然可以正常启动, 并维 持低速运转, 车辆能缓慢行驶, 不会危及交通安全。 油门位置智能控制器和防 止驾驶员打瞌睡模块可通过插接件并联或串联于原车油门位置传感器输出线路 中, 安装简单方便。 不对原车辆进行任何改动, 即可实现防止驾驶员打瞌睡的 目的。 油门位置智能控制器在完全失效的情况下也不会影响车辆的正常运行。 不用改变原车线路, 无需接线, 无需专业人员, 运营和维护成本低。 防止驾驶 员打瞌睡模块与汽车 OBD接口数据配合使用效果更好。
[0062] 以上内容是结合具体的实施方式对本发明所作的进一步详细说明, 不能认定本 发明的具体实施只局限于这些说明。 对于本发明所属技术领域的普通技术人员 来说, 在不脱离本发明构思的前提下, 还可以做出若干简单推演或替换。
