Description

一种车辆节能减排辅助系统、辅助方法及汽车 技术领域
本发明属于汽车辅助驾驶技术领域，具体涉及一种车辆节能减排辅助系统、辅助方法及汽车。
背景技术
汽车的发明给人类的出行及货物运输带来了便利，但同时也因能源的消耗带来了环境污染和资源枯竭等问题，如何能够在满足使用需求的基础上，减少能源消耗和尾气污染物排放，已是各大汽车厂商共同追求的目标。
汽车在行驶过程中，由于发动机工作工况复杂多变，不能一直工作在热效率高的区域，但如果能有一些方法使其尽可能多的工作在热效率高的区域，那么也能带来节能减排的效果。
现有技术中，通过控制发动机尽可能多的工作在热效率高的区域，进而带来节能减排效果的技术方案中，往往存在以下技术问题：
1、现有技术中，有些技术方案会通过分析后，根据分析结果主动干预车辆的驾驶状态，以使车辆发动机工作在热效率高的区域，该方案会根据车辆行驶状态进行主动干预，这样容易使驾驶员产生失控感，或因自动控制的参与使车辆违背驾驶员的驾驶意图，甚至在某些条件下容易引起安全事故。
2、现有技术中，有些技术方案以显示提醒的方式，使驾驶员在系统的提示下主动修正驾驶行为，该方案通过对车辆行驶状态进行监控，当车辆加速度超限或车速超限时会有轻踩油门的提示，当车辆怠速时间超限时会有熄火提示，当车辆挡位使用不当时会有换挡提示，但这些指令的发出均基于单一因素，并未考虑车辆自身的状态及车辆所处的路况条件等因素，导致所发出的有些提示 并不科学，甚至会误导驾驶员，对节能减排和安全驾驶不利，同时，缺少对驾驶员显示车辆的实时油耗水平及最佳油耗的工作区域等信息，使驾驶员不清楚如何调整车辆状态到最佳油耗区。

具体实施方式
为清楚、完整地描述本发明所述技术方案及其具体工作过程，结合说明书附图，本发明的具体实施方式如下：
实施例一：
本实施例一公开了一种车辆节能减排辅助系统，如图1所示，所述车辆节能减排辅助系统包括车辆数据全面检测模块、数据采集模块、数据处理模块、提示信息判断模块、计时器、油耗监测模块以及终端模块。
所述车辆信息全面检测模块包括：
油门踏板开度传感器，与数据采集模块信号连接，用于检测油门踏板开度， 并将油门踏板开度数据发送至数据采集模块；
车速传感器，与数据采集模块信号连接，用于检测车速，并将车速数据发送至数据采集模块；
车距测量单元，与数据采集模块信号连接，用于检测本车与周围车辆或周围障碍物之间的车辆间距，并将车辆间距数据发送至数据采集模块，本实施例一中，所述车距测量单元采用车距测量雷达；
发动机水温传感器，与数据采集模块信号连接，用于检测发动机冷却水温度，并将发动机水温数据发送至数据采集模块；
空调启停检测单元，与数据采集模块信号连接，用于检测空调的启停状态，即检测空调处于开启状态还是关闭状态，并将空调启停状态数据发送至数据采集模块，本实施例一中，所述空调启停检测单元为空调开关；
挡位传感器，与数据采集模块信号连接，用于检测车辆的挡位状态，并将车辆的挡位状态数据发送至数据采集模块。
电瓶电压检测单元，与数据采集模块信号连接，用于检测车辆电瓶电压，并将电瓶电压数据发送至数据采集模块；
电瓶电量消耗检测单元，与数据采集模块信号连接，用于检测车辆电瓶电量消耗，并将电量消耗数据发送至数据采集模块；
车辆停车怠速检测单元，与数据采集模块信号连接，用于检测车辆停车怠速时长，并将车辆停车怠速时长数据发送至数据采集模块；
所述数据采集模块通过整车的CAN线分别与所述车辆数据全面检测模块中的油门踏板开度传感器、车速传感器、车距测量单元、发动机水温传感器、空调启停检测单元、挡位传感器、电瓶电压检测单元、电瓶电量消耗检测单元和车辆停车怠速检测单元信号连接，用于接收车辆数据全面检测模块输出的油门踏板开度数据信息、车速数据信息、车辆间距数据信息、发动机水温数据信息、空调启停状态数据信息、挡位状态数据信息、电瓶电压数据信息、电量消耗数 据信息以及车辆停车怠速时长数据信息，所述数据采集模块将接收到的各数据信息进行整合后通过整车的CAN线发送至数据处理模块。
所述数据处理模块内存储有预先设置的各车辆状态数据信息的对应关系数据、车辆换挡策略、车辆停车怠速时长限值、电瓶电压正常值范围、发动机水温正常值范围以及电瓶电量消耗正常值范围；
所述对应关系数据为车辆在保证行车安全的基础上使车辆发动机工作在高热效率区域时，相关车辆状态数据信息的最佳值对应关系；
所述预先设置的各车辆状态数据信息的对应关系数据包括：
(1)加速度限值与车速的对应关系数据，如图3所示；
所述“加速度限值与车速的对应关系数据”的制定依据为：如果车辆加速度太大即通常所说的急加速，这时车辆的油耗会急剧升高，不利于节能减排，故以此为依据制定加速度限值与车速的对应关系，当前车速下，若车辆的加速度在对应的加速度限值之下，则车辆油耗将区域平稳，实现节能减排；
(2)最高车速与水温的对应关系数据，如图4所示；
所述“最高车速与水温的对应关系数据”的制定依据为：车辆冷启动时，水温一般都比较低尤其是冬季，这种情况下，如果车辆快速行驶时油耗及磨损都比较严重，故以此为依据制定车辆允许的最高车速与水温的对应关系数据，当前水温下，在对应的最高车速下行使，既节能减排又能延长车辆的使用寿命；
(3)车间距分别与最高车速限值、最低车速限值的对应关系数据，，如图5所示；
所述“车间距分别与最高车速限值、最低车速限值的对应关系数据”的制定依据为：在一定的距离内，如果车速过高，制动距离会加大，容易引发交通事故，对安全驾驶不利；如果车速过低，则会使发动机工作在燃油消耗率相对较高的区域，引起车辆的油耗和排放增加，故以此为依据制定当前车间距下，最高车速限值与最低车速限值，当前车间距下，在对应的最高车速限值与最低 车速限值区间行驶，既能保证行车安全，又能使发动机工作在热效率较高区域，从而达到节能减排的效果；
所述数据处理模块，用于接收所述数据采集模块发送的各车辆信息数据，分析各车辆信息数据进而判断车辆驾驶状态，并通过调用相应车辆信息的对应关系数据，并与预先设置的各车辆状态数据信息的对应关系数据、车辆换挡策略、车辆停车怠速时长限值、电瓶电压正常值范围、发动机水温正常值范围以及电瓶电量消耗正常值范围进行比对，以获得需要修正的驾驶行为的提示指令；
所述提示指令包括：“请缓加速”、“请勿抖动”、“请减速”、“请加速”、“请升挡”、“请降挡”和“请熄火”；
(1)当数据处理模块接收到油门踏板开度数据信息与车速数据信息，油门踏板开度数据信息进行处理转换为加速度信号后，如图3所示，与内置预设的加速度限值与车速的对应关系数据进行比对，若当前车辆的加速度值大于当前车速对应的加速度限制，则说明此时驾驶员处于急加速状态，车辆油耗急剧升高，故数据处理模块发出“请缓加速”提示指令；
(2)当数据处理模块接收到油门踏板开度数据信息与车速数据信息，油门踏板开度数据信息进行处理转换为加速度信号后，如图3所示，与内置预设的加速度限值与车速的对应关系数据进行比对，如果在预设的时间段内，连续发生两次以上当前车辆的加速度值大于当前车速对应的加速度限制的情况(加速度限值可根据车辆状态设定)，则判定驾驶员驾驶习性不良，故数据处理模块发出“请勿抖动”提示指令；
(3)当数据处理模块接收到发动机水温数据信息与车速数据信息，如图4所示，与内置预设的最高车速与水温的对应关系数据进行比对，若当前车速值大于当前水温对应的最高车速，则判断当前车速下车辆行驶油耗及磨损均较为严重，故数据处理模块发出“请减速”提示指令；
(4)当数据处理模块接收到车辆间距数据信息与车速数据信息，如图5 所示，与内置预设的车间距分别与最高车速限值、最低车速限值的对应关系数据进行比对，若当前车速值大于当前车辆间距对应的最高车速限值，则判断当前车速较快，制动距离会加大，容易引起交通事故，对安全驾驶不利，故数据处理模块发出“请减速”提示指令；若当前车速值小于与当前车辆间距对应的最低车速限值，则判断当前车速较低，发动机此时工作在燃油消耗率相对较高的区域，引起车辆的油耗和排放增加，故数据处理模块发出“请加速”提示指令；
(5)当车辆处于手动挡控制模式下，数据处理模块接收到挡位状态数据信息，并与内置的挡位策略下当前车速所对应的挡位进行比对，如图6所示，若车辆当前挡位低于当前车速所对应的挡位，则数据处理模块发出“请升挡”提示指令；若车辆当前挡位高于当前车速所对应的挡位，则数据处理模块发出“请降挡”提示指令，以降低车辆的油耗和排放，且提升驾驶员驾驶体验；
(6)当车辆无起停功能或起停功能关闭工况下，车辆处于停车怠速状态下，数据处理模块接收到发动机水温数据信息、空调启停状态数据信息、挡位状态数据信息、电瓶电压数据信息、电量消耗数据信息以及车辆停车怠速时长数据信息，当电瓶电压处于电瓶电压正常值范围内，空调处于关闭状态，电量消耗值处于电瓶电量消耗正常值范围内，发动机水温处于发动机水温正常值范围内，挡位状态处于空挡，且车辆停车怠速时长超过车辆停车怠速时长限值，则数据处理模块发出“请熄火”提示指令；
所述数据处理模块将发出的指示指令信息通过整车的CAN线发送至信息判断模块作进一步分析处理。
所述信息判断模块对接收到的提示指令信息进行判断，如为新类型的提示指令信息，则直接通过整车的CAN线发送至终端设备，如为重复类型的提示信息，则通过整车的CAN线发送至计时器。
所述计时器内设有多个计时通道，不同的计时通道对应不同类型的提示指 令信息，且不同计时通道分别设置计时时长，当计时器接收到信息判断模块发送的重复类型的提示指令信息后，该类型提示指令信息对应的计时通道被触发，开始倒计时，当该计时通道倒计时结束后，如仍有该类型的提示指令发来，则计时器将该提示指令信息通过整车的CAN线发送至终端模块，且该计时通道计时复位，待下次对应类型提示指令信息再次传来，再次触发倒计时。
所述油耗监测模块，包括实时油耗检测单元和最佳油耗工况区域存储单元；

    S2：分析处理采集到的车辆信息，判断车辆驾驶状态，并与预先设置的各车辆状态数据信息的对应关系数据、车辆换挡策略、车辆停车怠速时长限值、电瓶电压正常值范围、发动机水温正常值范围以及电瓶电量消耗正常值范围进行比对，以获得需要修正的驾驶行为的提示指令；
    S3：判断提示指令，如为新类型的提示信息则进行提示，如为重复类型的提示信息则开始倒计时，倒计时结束后若仍获得重复类型的提示信息，则进行提示。
  8. 如权利要求7所述一种车辆节能减排辅助系统的辅助方法，其特征在于：
    所述步骤S2中，获得需要修正的驾驶行为的提示指令的过程包括：
    油门踏板开度数据信息进行处理转换为加速度信号后，和车速数据信息一同与内置预设的加速度限值与车速的对应关系数据进行比对，若当前车辆的加速度值大于当前车速对应的加速度限制，获得“请缓加速”提示指令；
    油门踏板开度数据信息进行处理转换为加速度信号后，和车速数据信息一同与内置预设的加速度限值与车速的对应关系数据进行比对，如果在预设的时间段内，连续发生两次以上当前车辆的加速度值大于当前车速对应的加速度限制的情况，获得“请勿抖动”提示指令；
    将发动机水温数据信息与车速数据信息与内置预设的最高车速与水温的对应关系数据进行比对，若当前车速值大于当前水温对应的最高车速，获得“请减速”提示指令；
    将车辆间距数据信息与车速数据信息与内置预设的车间距分别与最高车速限值、最低车速限值的对应关系数据进行比对，若当前车速值大于当前车辆间距对应的最高车速限值，获得“请减速”提示指令；若当前车速值小于与当前车辆间距对应的最低车速限值，获得“请加速”提示指令；
    当车辆处于手动挡控制模式下，将挡位状态数据信息与内置的挡位策略下当前车速所对应的挡位进行比对，若车辆当前挡位低于当前车速所对应的挡位，则获得“请升挡”提示指令；若车辆当前挡位高于当前车速所对应的挡位，则获得“请降挡”提示指令；
    当车辆无起停功能或起停功能关闭工况下，车辆处于停车怠速状态下，数据处理模块接收到发动机水温数据信息、空调启停状态数据信息、挡位状态数据信息、电瓶电压数据信息、电量消耗数据信息以及车辆停车怠速时长数据信息，当电瓶电压处于电瓶电压正常值范围内，空调处于关闭状态，电量消耗值处于电瓶电量消耗正常值范围内，发动机水温处于发动机水温正常值范围内，挡位状态处于空挡，且车辆停车怠速时长超过车辆停车怠速时长限值，则获得“请熄火”提示指令。
  9. 如权利要求7或8所述一种车辆节能减排辅助系统的辅助方法，其特征在于：
    在所述车辆节能减排辅助方法进行过程中，实时分析并获得车辆的实时油耗及与车辆行驶状态工况相匹配的最佳油耗工况区域，并实时显示所述实时油耗及最佳油耗工况区域。
  10. 一种汽车，其特征在于：
    所述汽车上安装有如权利要求6所述的车辆节能减排辅助系统。
