Description

车辆的消耗显示系统
本发明一种涉及车辆、尤其机动车的消耗显示系统,其具有至少一个显示器以显示消耗信息,并具有工具以检测车辆的当前能量消耗,并具有计算单元以根据所检测的能量消耗来生成要在该显示器上显示的消耗信息,以及具有与该计算单元相连的导航系统。
另外本发明还涉及一种用于运行尤其如上所述的车辆消耗显示系统的方法,该消耗显示系统具有一个显示器,在该显示器上根据车辆的能量消耗来来显示消耗信息,并且其中与车辆的导航系统交换数据。
现有技术
消耗显示系统以及其运行方法由现有技术中已知。由于总是更强的环保意识以及上升的燃料价格,对车辆能量消耗、尤其燃料消耗的关注在增加。每个驾驶员的个人驾驶方式在路段相同时可能关于能量消耗而导致完全不同的结果。为了提高驾驶员对其能量消耗的意识,已知的是在车辆中设置消耗显示系统,其根据所检测的能量消耗来向驾驶员显示消耗信息。从而尤其已知的是,通过该消耗显示系统的显示器向驾驶员显示当前的能量消耗、尤其当前的燃料消耗。计算单元为此对用于检测当前能量消耗的工具的数据进行分析,以便产生相应的消耗信息。这种消耗显示系统比如在欧洲专利申请EP 1 018 449 A2中已公开。所公开的该系统在一个显示器上同时显示当前的瞬态消耗以及平均消耗。另外在该文件中还公开,把车辆的导航系统整合在该消耗显示系统中,以能够除了当前的燃料消耗之外还显示要行驶路段的估计燃料消耗。由此对于驾驶员能够将他的当前消耗与估计的消耗相比较,并必要时匹配他的驾驶方式。
本发明的公开
根据本发明的消耗显示系统相对于现有技术而具有的优点是,驾驶员能够获知他自己的与路段有关的能量消耗,并被促进以不断改善他的能量消耗。根据本发明这通过如下来实现,即该消耗显示系统的计算单元存储由该导航系统所检测的至少一个开始点和目标点对和/或相应所行驶的路段以及在相应地开始点和目标点之间所检测的至少一个消耗值,并在需要时、也即比如按照驾驶员的要求而在显示器上进行显示。根据本发明的消耗显示系统从而规定,考虑该导航系统的数据,并从而能够给驾驶员显示与所行驶路段有关的消耗信息。驾驶员从而比如能够把所行驶的路段的消耗值相互比较。因此能够把他多次行驶的路段的消耗值相互比较,由此促进他来匹配他的驾驶行为,或者关于能量消耗而进行改善。在此该计算单元可以仅仅存储具有至少一个所属消耗值的一个路段的开始点和目标点。另外该计算单元也可以存储具有至少一个所属消耗值的实际行驶路段。所检测的开始点和目标点对以及所行驶的路段分别是实际开始行驶的点以及车辆所位于的行驶路段以及该驾驶员连同他的车辆已经行驶过的路段。从而能够尤其在启程之前向驾驶员显示已经存储的具有至少一个所属消耗值的路段,并为该导航系统选择对于他匹配的路段或者具有目前最佳消耗值的路段。另外该驾驶员由此能够在行驶结束时与至少一个、优选多个存储的消耗值关于开始点和目标点对或所行驶的路段相比较而显示由他所经历的消耗值。尤其优选地显示一个列表,其具有最佳的消耗值以及他当前经历的消耗值以进行比较。
如果当前路段的至少该开始点和目标点对与所存储的消耗值的开始点和目标点对相一致,那么就优选地在该消耗显示系统的显示器上显示所述至少一个存储的消耗值连同至少一个当前的消耗值。所存储的消耗值的开始点和目标点对在此可以理解为所存储的消耗值所分配给的或者通过该计算单元所分配的开始点和目标点对。通过同时显示所存储的消耗值和当前的消耗值,其中这两者都分配给相同的开始点和目标点对,给驾驶员以简单的方式和方法来表明他当前的驾驶行为关于能量消耗而与之前的驾驶行为有什么不同。从而总是促进该驾驶员再次达到或甚至缩短之前所经历的消耗值。
如果当前行驶的或由该导航系统所预先给定的路段与分配给所存储消耗值的所存储路段不一致,那么就尤其优选地在该显示器上显示所述至少一个所存储的消耗值以及所述至少一个当前消耗值。如果该计算单元借助该导航系统的数据而识别出该驾驶员行驶或将行驶已经行驶过的路段,那么就至少显示之前对该路段所存储的消耗值以及至少一个当前的消耗值,如此使得该驾驶员在该路段上的每个时间点都能够关于他之前的驾驶行为而估计并必要时优化他的驾驶行为。
优选地该计算单元根据由该导航系统所选择的路段来计算理论消耗值。在此规定,该计算单元在知道所选择的、也即要行驶的路段的情况下来计算至少一个理论消耗值。这比如可以借助发动机数据或发动机特征曲线以及必要时其他的在该导航系统中所存储的数据来进行。这可以为该驾驶员用作他驾驶行为的附加定向或指示。
优选地从所存储的消耗值中选择最低的消耗值并与当前的消耗值一起被显示。如果针对一个开始点和目标点对和/或针对某一路段已经检测并存储了多个消耗值,因为该驾驶员已经多次从该开始点行驶到该目标点,那么就优选地选择最低的消耗值并连同当前的消耗值一起来显示,以给该驾驶员呈现他目前关于消耗值的最佳记录,并由此促进他进一步消耗优化的驾驶行为。
尤其优选地作为至少一个消耗值来检测或计算一个平均消耗值和/或瞬态消耗值。该平均消耗值是在整个路段上从开始点到目标点或到当前位置而体现平均消耗的一个值。自然也可以检测或计算并显示部分平均消耗值。瞬态消耗值是在该路段的相应位置上所检测的相应当前消耗。
根据本发明的另一有利的改进而规定,如果所检测的一个开始点和目标点对与所存储的开始点和目标点对相一致,那么该导航系统就选择具有最低的所存储消耗值的路段。如果该驾驶员事先已经表明他想消耗优化地旅行,那么就尤其是这样的。这可以比如通过该导航系统或者通过选择消耗优化的驱动级别来显示给该驾驶员。
优选地给该计算单元分配了输入装置,借助该输入装置驾驶员可以输入他的名字,该名字连同所检测的开始点-目标点对和/或所行驶的路段、并尤其连同日期和/或时间一起被存储。由此可以把所述至少一个消耗值分配给已经达到该消耗值的驾驶员的名字。优选地该计算单元在需要时显示具有比如五个或十个最佳消耗值的表格,其中在每个消耗值处另外还显示日期、时间和/或驾驶员名字。从而在其行驶结束时能够给该驾驶员显示表格或最佳列表(Top 10,前10),并看到他以他的消耗值处于第几位,或者他的消耗值与已经经历的消耗值相比如何。该输入工具可以是该导航系统所提供的输入工具,或者可以设置附加的输入工具。
优选地该消耗显示系统作为组合仪表来构造。通常车辆的组合仪表由速度表、油箱指示、冷却剂温度指示器、控制灯和行驶方向指示以及必要时的转速计的组合来组成。在该情况下,在该组合仪表中对于驾驶员可见地另外还集成了该消耗显示系统的显示器。该消耗显示系统优选地通过车辆的CAN总线与为检测消耗而设置的工具、如速度和/或转速传感器以及内燃机的喷射系统和/或与该导航系统相连。
根据本发明的方法特征在于,由该导航系统所检测的至少一个开始点和目标点对和/或所行驶的路段以及在该开始点与该目标点之间所检测的至少相应一个消耗值被存储并在需要时在该显示器上被显示,尤其如前文中关于该消耗显示系统所述。尤其优选地,如果当前所行驶路段的至少该开始点和目标点对与所存储消耗值的该开始点和目标点对相一致,那么把至少一个所存储的消耗值与至少一个当前的消耗值一起在该显示器上来显示。优选地,如果另外当前行驶的或通过该导航系统所预先给定的路段与所存储的路段相一致,那么就把至少一个所存储的消耗值连同至少一个当前的消耗值一起在该显示器上来显示。尤其优选地从所存储的消耗值中选择最低的消耗值,并连同所述至少一个当前的消耗值一起来显示,以促进驾驶员更加消耗优化地改进他的驾驶行为。优选地检测或计算至少一个瞬态消耗值和/或至少一个平均消耗值。尤其规定,如果所检测的开始点和目标点对与所存储的开始点和目标点对相一致,那么该导航系统就选择具有最低的所存储消耗值的路段。
通过本发明的方法尤其获得了以下的优点,即能够在启程之前向驾驶员显示所存储的路段连同他的消耗,以选择适合他的路段和/或在经济上最有意义的路段。另外驾驶员还可以在行驶期间把他的当前消耗值与所存储的消耗值相比较,由此促进他总是达到新的消耗最佳值,或者进一步降低他的能量消耗。
下面本发明应该借助附图来更详细解释,其中:
唯一的附图以示意图示出了一个消耗显示系统。
附图以示意图示出了机动车的消耗显示系统1。该消耗显示系统包含有屏幕或显示器2,其上可以给机动车的驾驶员至少显示消耗信息。另外该消耗显示系统1还包含有计算单元3,其中该计算单元确定要在该显示器2上显示的信息。该计算单元3另外还与用于检测车辆当前能量消耗的工具4相连接。该工具4在该情况下是用于检测机动车当前速度v的一个单元5,其中该单元5在此优选地包含有至少一个速度传感器和/或转速传感器。作为其他的工具4还采用了车辆1的发动机控制设备6。该发动机控制设备6把数据续传到该计算单元3,其中该数据涉及该机动车的当前能量消耗。在此如果该机动车具有由内燃机和至少一个电机组成的所谓混合驱动,那么该数据不仅可以涉及电能消耗,而且还可以涉及机动车的燃料消耗。但出于简化在该实施例中从仅仅具有内燃机来作为驱动机的机动车出发,如此使得该发动机控制设备6向该计算单元3传输该内燃机的燃料喷射系统的数据d。
根据与速度和喷射系统有关的数据v、d,该计算单元3借助消耗计算装置7来首先计算瞬态消耗值a以及平均消耗值b。该瞬态消耗值体现为该机动车的当前燃料消耗,而该平均消耗值b体现为自行驶开始或自另一由驾驶员选择的开始点以来机动车的平均消耗。
另外该计算单元3还包含有一个装置8,其中给该装置传输了该瞬态消耗值a以及该平均消耗值b。该装置8确定应该把哪个值以及该值如何在该显示器2上来显示。那么该装置8比如就可以确定把该瞬态消耗值a和该平均消耗值b同时在该显示器2上来显示。该装置8具有非易失的存储器9,在该存储器中可以存储或存放消耗值、也即瞬态消耗值a和平均消耗值b。
另外该消耗显示系统1还与该机动车的一个导航系统10相连接,如此使得该导航系统10在该情况下构成该消耗显示系统1的组成部分。代替地该消耗显示系统1自然也可以作为该导航系统10的组成部分来构造,其中该计算单元3和该显示器2在此优选地是该导航系统的计算单元以及显示器。该导航系统10检测一个开始点以及一个目标点以及可选的该驾驶员在该开始点和目标点之间已经历的路段。行驶路段的开始点和目标点对以及必要时该路段本身被传输到该装置8,该装置把由该导航系统10所获得的数据与由该消耗计算装置7所获得的消耗数据相逻辑关联,如此使得给所检测的开始点-目标点对和/或所行驶的路段分配至少一个所属的消耗值,并连同该开始点-目标点对和/或该路段一起被存储在该存储器9中。如果该计算单元3借助该装置8检测到当前所检测的开始点-目标点对对应于已经存储的开始点-目标点对,那么它就在该显示器2上除了当前所检测的消耗值a和b之外还显示事先存放在该存储器9中的、分配给该开始点和目标点对的一个或多个消耗值。从而给该机动车的驾驶员同时显示当前的消耗值以及较早的消耗值,由此该驾驶员可以把他目前的驾驶行为直接与他之前的驾驶行为关于能量或燃料消耗来相比较,并必要时可以匹配或优化。优选地该计算单元3或该装置8从所存储的消耗值中选择在该开始点和目标点对的开始点和目标点之间曾经检测的最低消耗值。优选地显示所存储的其中所行驶的路段与所存储的路段相一致的消耗值。
优选地另外在该导航系统10和该计算单元3或该装置8之间如此进行通信,使得如果该装置8识别出由该导航系统10所期望的开始点-目标点对与已存储的开始点和目标点对相一致,那么该计算单元8就向该导航系统10传输被分配给所存储开始点和目标点对的消耗值,如此使得该导航系统10借助所存储的消耗值来选择具有最低的所存储消耗值的路段。由此能够借助该导航系统10给该驾驶员预先给定一个路段,其中该路段在他个人驾驶行为的情况下产生最低的消耗值。代替地,该装置8也可以选择在所期望的开始点和目标点对之间具有最低消耗值的路段,并传输到该导航系统10。同样也可以考虑在该显示器2上或者在该导航系统10的显示器上除了在一个所期望的开始点和目标点对之间提供用于选择的多个路段之外,还显示对于相应路段所存储的最低消耗值,如此使得该驾驶员自己就可以决定目前哪个路段对于他是最合适的。
如果该驾驶员多次行驶过一个开始点和目标点对,那么比如就可以总是给该驾驶员显示目前为止最低的消耗值、尤其最低的平均消耗值,由此该驾驶员就可以把他当前的消耗与所存储的消耗相比较,这致使促进该驾驶员总是达到新的消耗最佳值,并降低他的消耗,或匹配他的驾驶行为以获得更低消耗。也可以在启程之前给该驾驶员显示在开始点和目标点对处所存储的路段连同相应所存储的消耗值,并选择为他匹配的或经济上最有价值的路段。
为了使该消耗显示系统1的存储需求保持为微小,优选地仅存储与开始点和目标点对和/或所行驶的路段有关的最低消耗值。那么如果检测到开始点和目标点对和/或路段的新消耗值,其中该消耗值低于相应所存储的消耗值,那么就把已存储的消耗值替换为当前所检测的消耗值。
该消耗显示系统可以与所行驶的或所预先给定的路段无关地、或者也根据所行驶的路段来确定或使用开始点-目标点对的消耗值。该消耗显示系统1优选地通过在此未示出的CAN总线与该工具4和该导航系统10相连接以进行数据交换。优选地该消耗显示系统1作为机动车的组合仪表来构造,如此使得它除了该消耗值和必要时的导航数据之外,还包含或显示速度、剩余燃料量、冷却剂或该内燃机的温度、必要时的控制灯和/或转速表以及行驶方向指示。
该导航系统10优选地借助GPS数据、尤其与车辆的驾驶员是否已经激活该导航系统10以引导该驾驶员无关地来检测行驶的开始点和目标点和/或所行驶的路段。如果该驾驶员激活该导航系统10以进行引导,那么如前所述,有利地给他显示/示出到达目的地的不同路段的选择、连同之前所检测的最低消耗值、或必要时理论计算的消耗值。
