Description

车辆供油调节装置
技术领域
本发明涉及一种用于机动车的自动供油调节装置。 背景技术
众所周知, 机动车在空挡滑行时, 只消耗怠速供油。 此时, 机 动车的加速、 减速、 匀速运动符合牛顿力学理论及下面的公式:
(1) (2) (3) (4) 其中: m为机动车的质量, V。为初速度, ¼为末速度, t为从 V0到 Vt的行驶时间, a为加速度, S为上述 t时间段的行驶距离。
公式 S = V0t + at2/2可以变形为 S - VGt = at2/2,为了方便计算和 获得结论, 一个具有初速度¼的机动车加速行驶了 t时间后它所行 驶的距离可以^ 为定义分为二部分: 一部分定义为初速度距离为 V0t, 另一部分视为加速度距离, 即: S-V0t, 我们来比较加速度、 牵引力和加速度距离之间的关系。 机动车在加速度为 a的状态下总 共行驶了 S的距离, 按照上面的定义, 其加速度距离为: S- V0t, 而机动车在初速度为 Vo和加速度为 na的状态下总共行驶了 Sn的距 离, 按照上面的定义, 其加速度距离为: Sn- V0t, 因此:
( Sn - V0t )/ (S - V0t) =n (5) 由 F = ma可以看出, 牵引力和加速度是线性关系, 牵引力增加 了 n倍, 则加速度也增加了 n倍, 而机动车行驶的加速度距离也增 加了 n倍, 在同一挡位下可以近似认为, 牵引力增加 n倍, 油耗也 增加了 n倍。 上述公式同时也适用于机动车的匀速状态, 因为, 匀 速状态可以视为加速度为无限小。
目前, 所有的机动车都是通过驾驶员对油门踏板的操纵来调节 发动机的输出功率。 驾驶机动车的过程中, 有经驗的驾驶员有意识 地短时间松开油门, 使得机动车短时间内处于滑行状态, 以此节约 燃油。 但是在驾驶过程中通过人为操作的方式反复松开油门一方面 会使驾驶员非常疲倦, 另一方面驾驶员很难把握松开油门的最好时 机。 这样达不到最佳的节油效果。 发明内容
本发明的目的在于提出一种自动供油调节装置, 该装置通过按 设定的方式调节发动机的供油实现节油目的。
本发明是将机动车的匀速行驶变为小范围的加速和滑行行驶, 通过上述分析可以得知机动车在同等油耗下加速行驶和勾速行驶理 论上并没有损失行驶距离, 而滑行时却只消耗发动机怠速的燃油, 因而达到省油的目的。
根据本发明, 提出一种用于机动车的自动供油调节装置, 该自 动供油调节装置包括一个车速传感器、 一个行驶状态传感器和一个 油门传感器, 其特征在于: 该自动供油调节装置还包括一个空占比 单元, 油门传感器、 车速传感器以及行驶状态传感器与该空占比单 元连接, 其中
a )在油门传感器感知到油门踏板前进时, 空占比单元占运行, 从而开启力 p油油路, 发动机进行加油供油;
b )在油门传感器感知油门踏板前进保持时, 空占比单元保持占 运行直至行马史状态传感器感知机动车达到匀速状态时, 空占比单元 按一个设定的速度差值进行空占运行, 即循环交替进行空运行和占 运行;
c )在油门传感器感知油门踏板回退或回退到某一位置保持时, 空占比单元空运行, 关闭加油油路,使得发动机处于怠速供油状态。 车速传感器的重要功能是在空占比单元空运行时不断测量机动 车速度变化, 当该变化量达到一个设定的速度差值时(该设定的速 度差值可以由驾驶员操纵一个设置在驾驶室内的旋钮实现),由空运 行变为占运行或者相反, 周而复始。
在本发明中, 发动机的供油处于占运行表示按本发明的自动供 油调节装置的空占比单元不干预发动机的供油系统, 使得供油系统 可以向发动机供给由油门踏板位置决定的供油量; 发动机的供油处 于空运行表示按本发明的自动供油调节装置的空占比单元控制供油 系统仅向发动机供给保持发动机怠速所需的供油量; 发动机的供油 处于空占运行表示占运行和空运行交错地进行。 按本发明的自动供 油调节装置的空占比单元在空占运行中的占运行时不干预发动机的 供油, 在空占运行中的空运行时仅向发动机供给保持发动机怠速所 需的供油量。
按本发明的一种优选的实施方式, 所述空占比单元可以是一个 设置在加油油路上的电磁油路节流阀。在电子控制喷射的发动机中, 所述空占比单元也可以是一个控制电控喷油装置的喷油量的控制装 置。
- 按本发明的一种优选的实施方式, 所述自动供油调节装置具有 一个在传动系统中设置在发动机下游的与空占比单元作用连接的电 控离合器, 当空占比单元占运行时, 电控离合器结合; 当空占比单 元空运行时, 电控离合器分离。 通过这项措施, 可以进一步节约燃 油。 所述电控离合器在传动系统中优选安装在最后一级传动轴上。
有利的是, 当空占比单元进入空占运行时, 首先空运行, 直到 机动车速度下降幅度达到设定的速度差值, 然后进入占运行, 直到 行驶状态传感器检测到机动车达到匀速状态, 然后进入空占运行的 下一个循环。 同样有利的是, 当空占比单元进入空占运行时, 首先占运行, 发动机处于增加供油的加速供油状态, 当机动车速度上升幅度达到 设定的速度差值时, 然后进入空运行, 直至机动车速度下降幅度达 到设定的速度差值, 期间仅怠速供油, 然后进入空占运行的下一个 循环。
所述设定差值通过一个在驾驶室内设置的旋钮由驾驶员设定。 所述设定的速度差值在 0至 50km/h范围内, 特别是在 5至 20km/h 的范围内。 当设定的速度差值为 0时,相当于使机动车始终占运行。
油门前进到一定程度, 一般情况下, 在油门踏板满行程的 70% 以上时,说明驾驶员希望机动车大转矩输出, 而不要求其经济性能, 这时, 占空比单元占运行。
根据本发明还提出一种用于机动车的自动供油调节装置, 该自 动供油调节装置包括一个车速传感器、 一个行 3史状态传感器和一个 油门传感器, 其特征在于: 该自动供油调节装置还包括一个空占比 单元, 空占比单元与车速传感器、 油门传感器和行驶状态传感器连 接, 其中
a )在油门传感器感知到油门踏板前进或回退时, 空占比单元占 运行, 即空占比单元不干预发动机的加油供油;
b )在油门传感器感知到油门踏板前进保持或后退保持时, 空占 比单元占运行直至行马史状态传感器感知到机动车达到匀速状态时, 空占比单元按一个设定的速度差值进行空占运行, 即循环交替进行 占运行和空运行。
当机动车通过按本发明的自动供油调节装置处于空占运行时, 在一个周期内, 占的时间和空的时间都是变化的。 由于每种不同型 号的机动车有着不同的加速性能, 对于不同性能的机动车, 其空占 比, 也就是占的时间和空的时间的比例, 是不同的。 附图说明

按本发明的用于机动车的自动供油调节装置包括一个车速传感 器、 一个行马史状态传感器 SS、 一个油门传感器 9和一个空占比单元 8, 所述车速传感器、 行驶状态传感器 SS和油门传感器与空占比单 元 8连接。 必要时, 所述自动供油调节装置还具有一个在传动系统 中设置在发动机下游的与空占比单元 8作用连接的电控离合器 7, 当空占比单元 8占运行时, 电控离合器 7结合; 当空占比单元 8空 运行时, 电控离合器 7分离。
图 1示出了按本发明的自动供油调节装置的控制逻辑图。 当油 门传感器 9感知到油门踏板 P前进时, 空占比单元 8占运行, 开启 加油油路, 发动机进行加油供油; 当油门传感器 9感知到油门踏板 P前进保持时,空占比单元 8占运行直到行驶状态传感器 SS感知机 动车达到匀速状态时, 空占比单元 8按设定的速度差值进行空占运 行; 而在油门传感器 9检测到油门踏板回退或回退到某一位置保持 时, 空占比单元 8空运行, 关闭加油油路, 使得发动机处于怠速供 油状态。
图 2示出了按本发明的空占比单元 8在进入空占运行之后的一 种优选的工作方式。 其中, 空占比单元 8首先空运行, 使得发动机 只得到怠速供油, 直到机动车速度下降幅度达到设定的速度差值, 然后空占比单元 8 占运行, 使得发动机加油供油, 直到行驶状态传 感器 SS检测到机动车达到匀速状态, 然后又进入空运行, 即进入空 占运行的下一个循环。
图 3示出了按本发明的空占比单元 8在进入空占运行之后的另 一种优选的工作方式。 当空占比单元 8进入空占运行时, 首先占运 行, 发动机处于增加供油的加速供油状态, 当机动车速度上升幅度 达到设定的速度差值时, 然后进入空运行, 直至机动车速度下降幅 度达到设定的速度差值, 期间仅怠速供油, 然后进入空占运行的下 一个循环。
图 4示出自动供油调节装置的一种实施形式。 油门传感器 9设 计成一个滑动变阻器 F, 油门踏板 P带动变阻器的滑动端 B。 滑动 变阻器 F的两端 A、 B输出的电阻和油门踏板的位置相对应, 当油 门踏板 P前进时, 电阻不断减小, 当油门踏板回退时, 电阻不断变 大, 或者相反。 根据电阻的变化, 经过一个电路 Ci可以识别出油门 前进、 油门回退、 油门前进保持以及油门回退保持等各种状态, 当 油门踏板例如处于满行程的 70 %至 100 %时, 对应一个特定范围的 电阻值, 因此当然也可以识别这种状态。 油门传感器 9、 车速传感 器 SV以及行驶状态传感器 SS经过电路 Ci与空占比单元 8以及必 要时的电控离合器 7连接。
图 5示出自动供油调节装置的另一实施例。 油门传感器 9设计 成一个直流发电机, 它设置在油门踏板 P的转动轴 N上,其中 K为 发电机转子, E为发电机定子, A'和 B'分别为引出线。 当油门踏板 前进时, 输出一个电动势, A'为正, B'为负, 或者相反; 当油门踏 板回退时, 输出一个电动势, A'为负, B'为正, 或者相反。 输出电 动势的大小与操纵油门踏板 P的速度大小相对应。 同样根据输出的 电动势通过一个电路 Ci可以识别出油门前进、 油门回退、 油门前进 保持以及油门回退保持等各种状态。 油门传感器 9、 车速传感器 SV 以及行驶状态传感器 SS经过电路 Ci与空占比单元 8以及必要时的 电控离合器 7连接。
图 6示出了按本发明的自动供油调节装置的另一种实施形式的 控制逻辑图。 在油门传感器 9感知到油门踏板 Ρ前进或回退时, 空 占比单元 8占运行, 即空占比单元 8不干预发动机的加油供油; 在 油门传感器 9感知到油门踏板 Ρ前进保持或后退保持时, 空占比单 元 8占运行直至行驶状态传感器 SS感知到机动车达到匀速状态时, 空占比单元 8按一个设定的速度差值进行空占运行, 即循环交替进 行占运行和空运行。
图 7a至 7c示出了安装本发明的自动供油调节装置的机动车的 一组油门踏板位置、 空占比单元 8工作状态和机动车行驶速度示意 图。 图 7a为油门踏板 P位置的示意图; 图 7b为空占比单元 8工作 状态的示意图, "1,, 表示占运行, "0" 表示空运行; 图 7c为机动 车行驶速度的示意图。从图 7可以看出, 当机动车进入匀速状态时, 空占比单元 8开始空占运行, 机动车的速度处于在最大速度 Vmax 和最小速度 Vmin之间, Vmax与 Vmin之间的速度差值由设定差值 确定。
下面为一辆机动车的试驗数据。 该机动车的车重为 2.5吨, 发 动机的功率可调范围为 0 - 200马力 (1马力 =735瓦)。 机动车设计 为 5挡,当机动车在公路上以每小时 80公里的速度平稳行驶时的油 耗为每 100公里 15公升, 通过采用按本发明的自动供油调节装置, 其中速度差值由驾马史员手动调节为 5公里, 当油门踏板踩到一定的 位置使得机动车在 77.5km/h至 82.5km/h的速度行驶, 这时机动车 滑行的距离遵循上述公式即: S = V。t + at2/2, 其中 t = ( Vt-V。)/a,Vt = 75.5公里 /小时, VQ - 82.5公里 /小时, F= 10%mg ( g为重力加速 度, 数值大约为 9.8 ) =2450000 N, m = 2500 kg, a = 0.98 m/S2, t = 5.1秒,这时空所滑行的距离 S = 131.5 m,在该距离下机动车只有怠 速油耗, 在占状态同时也遵循上述公式, 因此牵引的距离也为 131.5 m, 时间为 5.1秒, 这时的油耗由于加速而增加 50%, 节油量 2/1.5 -1=0.33 (即节油 33% )。
由此可见, 机动车获得了一定的滑行距离而省油, 由于机动车 在绝大部分的状态都是处于低于设计的极限速度行驶, 因此本发明 在机动车的非极限速度行驶的过程中使机动车节省 10% - 35%的燃 油消耗。
