为更进一步阐述本发明为达成预定发明目的所采取的技术手段及功 效, 以下结合附图及较佳实施例, 对依据本发明提出的车辆的悬挂分组控 制系统及悬挂分组控制方法其具体实施方式、 结构、 特征及功效, 详细说 明如后。
有关本发明的前述及其他技术内容、 特点及功效, 在以下配合参考图 式的较佳实施例详细说明中将可清楚的呈现。 通过具体实施方式的说明, 当可对本发明为达成预定目的所采取的技术手段及功效得以更加深入且具 体的了解, 然而所附图式仅是提供参考与说明之用, 并非用来对本发明加 以限制。
本发明主要是根据传感器感测结果自动进行悬挂分组, 同时还可对手 工输入悬挂分组进行判别并及时提供可视化报警, 提高了行驶的安全性。 同时具有强制分组功能, 方便传感器发生故障时, 也可进行悬挂分组。 故, 以下特举实例进行说明, 但本发明并不以此为限。
图 1 是本发明实施例提出的车辆的悬挂分组控制系统的主要架构方块 图。请参考图 1, 本实施例的车辆的悬挂分组控制系统包括悬挂分组选择开 关组 11、 报警器 12、 位置传感器 13 (第一传感器) 、 称重传感器 15 (第 二传感器) 、 控制器 17、 悬挂阔组 18以及悬挂装置 19。 在此, 控制器 17 与悬挂分组选择开关组 11、 报警器 12、 位置传感器 13、 称重传感器 15、 悬挂阔组 18皆电性连接。
位置传感器 13感测车辆是否带载, 即感测车辆是否载有物体。 称重传 感器 15感测车辆的载荷大小。 在其它实施方式中, 称重传感器 15还可以 替换为设置于车辆的轮胎上的压力和温度传感器、 或设置于悬挂装置 19的 悬挂油缸上的压力传感器。 当称重传感器 15替换为设置于车辆的轮胎上的 温度传感器时, 则温度传感器用以感测车辆轮胎的温度, 由于车辆轮胎的 温度高低对应于车辆的载荷大小, 从而可通过温度传感器感测的车辆轮胎 的温度获知车辆的载荷大小。
悬挂装置 19作为车辆的各个车桥 (也称车轴)与车架的连接件, 其通常 包括悬挂油缸与悬挂导向机构, 且数量为多个。 车辆的各轮组则安装在对 应的车桥上。 悬挂装置 19或者说悬挂油缸的悬挂分组模式选择正确可使得 车辆的各轮组具有均衡的牵引力, 从而保证车辆的安全行驶。 反之, 则车 辆可能会出现偏载现象。
控制器 17根据位置传感器 13与称重传感器 15的感测结果产生悬挂分 组结果、 并将悬挂分组结果作为确定最终输出的悬挂分组结果之参考。 悬 挂分组结果可以为悬挂分组模式。 例如悬挂装置 19(悬挂油缸)的悬挂分组 模式可以是控制器 17根据车辆是否带载与载荷大小而进行设定的。控制器 17还可根据所确定的悬挂分组模式通过 CAN总线 16发送总线数据控制车 辆的行驶速度。
具体地, 控制器 17根据位置传感器 13与称重传感器 15的感测结果产 生悬挂分组结果、 并将悬挂分组结果作为确定最终输出的悬挂分组结果之 参考的过程如下: 控制器 17可根据位置传感器 13的感测结果判断车辆是 否带载; 当判断车辆不带载, 则控制器 17建议第一悬挂分组模式。 例如第 一悬挂分组模式可以为预先设定的车辆正常行驶时悬挂装置 19(悬挂油缸) 的悬挂分组模式。 当控制器 17判断车辆带载, 则控制器 17根据称重传感 器 15提供的车辆的载荷大小建议第二悬挂分组模式。 控制器 17将建议的 悬挂分组模式作为参考并输出悬挂分组模式以对悬挂装置 19(悬挂油缸)执 行分组控制。 例如第二悬挂分组模式可以为车辆带载时的悬挂分组模式, 至于具体为哪种带载悬挂分组模式, 则需根据车辆的载荷大小进行选择, 以保证车辆的安全行驶, 使得各轮组趋于平均承载。
悬挂分组选择开关组 11, 可通过人为触发而输入悬挂分组模式至控制 器 17作为参考。 例如操作人员可以通过触发悬挂分组选择开关组 11 中之 一来选择输入悬挂分组模式。 悬挂分组选择开关组 11中还可包括强制分组 选择开关, 强制分组选择开关可通过人为触发而输入悬挂分组模式并强制 控制器 17接受所输入的悬挂分组模式, 即强制分组选择开关被人为触发后 能够强制设定控制器 17最终输出的悬挂分组结果。 强制分组选择开关的设 置主要是为了保证传感器在发生故障的条件下车辆仍能够进行悬挂分组, 以借此保证车辆可靠、 安全地行驶。 例如, 操作人员若发现控制器 17输出 的悬挂分组结果明显错误, 则通常表示传感器出现了故障, 这样, 操作人 员可通过触发强制分组选择开关而进行悬挂分组模式的强制设定。
报警器 12在控制器 17检测到强制分组选择开关被人为触发后, 由控 制器 17控制其提供报警提示。 在其它实施方式中, 强制分组选择开关未被 人为触发时, 根据实际应用需要也可设计控制器 17控制报警器 12提供必 要的报警提示。 在此, 报警器 12可以为声报警器, 光报警器或其组合。
悬挂阔组 18根据控制器 17输出的悬挂分组结果对悬挂装置 19进行分 组控制。
图 2是本发明实施例提出的车辆的悬挂分组控制方法的步骤流程图, 请一并参考图 2及图 1, 所述悬挂分组控制方法执行于控制器 17以对多个 悬挂装置 19(悬挂油缸)进行分组控制, 本发明实施例提出的车辆的悬挂分 组控制方法主要可包括以下步骤 S201~S216。
步骤 S201 , 控制器 17根据位置传感器 13的感测结果判断车辆是否带 载, 若判断车辆带载, 则进行步骤 S202, 若判断车辆不带载, 则进行步骤 S203 o
步骤 S202, 控制器 17根据称重传感器 15感测的车辆的载荷大小设定 悬挂装置 19(悬挂油缸)的悬挂分组模式, 并进行步骤 S205。
步骤 S203 , 控制器 17自动判断为正常行驶悬挂分组模式 (第一悬挂分 组模式), 再进行步骤 S206; 在此, 正常行驶悬挂分组模式也即车辆在不带 载情形下所采用的悬挂分组模式。
步骤 S205, 控制器 17自动判断为带载悬挂分组模式 (第二悬挂分组模 式), 再进行步骤 S206; 在此, 带载悬挂分组模式可根据载荷大小划分为多 种, 也即不同的载荷大小对应不同的带载悬挂分组模式。
步骤 S206, 控制器 17检测人为触发悬挂分组选择开关组 11而输入的 悬挂分组模式, 并判断自动判断的悬挂分组模式与人为触发输入的悬挂分 组模式是否一致, 若自动判断的悬挂分组模式与人为触发输入的悬挂分组 模式不一致则进行步骤 S208, 若自动判断的悬挂分组模式与人为触发输入 的悬挂分组模式一致则进行步骤 S212。
步骤 S208, 控制器 17判断是否人为触发悬挂分组选择开关组 11中的 强制分组选择开关, 即判断人为触发输入的悬挂分组模式是否为强制; 若 强制分组选择开关被人为触发, 即人为触发输入的悬挂分组模式为强制, 则进行步骤 S215; 若强制分组选择开关未被人为触发, 即人为触发输入的 悬挂分组模式不为强制, 则进行步骤 S210。
步骤 S210, 控制器 17控制报警器 12提供报警提示, 并按自动判断的 悬挂分组模式控制悬挂阀组 18对悬挂装置 19(悬挂油缸)进行分组控制, 再 进行步骤 S216。
步骤 S212, 控制器 17按自动判断的悬挂分组模式控制悬挂阔组 18对 悬挂装置 19(悬挂油缸)进行分组控制, 即控制器 17将自动判断的悬挂分组 模式作为输出, 再进行步骤 S216。 步骤 S215, 控制器 17控制报警器 12提供报警提示, 并按人为触发输 入的悬挂分组模式控制悬挂阀组 18 对悬挂装置 19(悬挂油缸)进行分组控 制, 即控制器 17 将人为触发输入的悬挂分组模式作为输出, 再进行步骤 步骤 S216, 控制器 17根据输出的悬挂分组模式通过 CAN总线 16发 送总线数据控制车辆的行驶速度。
在其它实施方式中, 当本发明实施例的车辆的悬挂分组控制系统未设 置悬挂分组选择开关组 11 及 /或未将最终确定的悬挂分组结果用作控制车 辆的车速的情形下, 相应地可省去步骤 S206、 S208、 S210、 S215、 及 /或步 骤 S216, 即在执行完步骤 S203或 S205后, 直接进行步骤 S212。
以上所述, 仅是本发明的较佳实施例而已, 并非对本发明作任何形式 上的限制, 虽然本发明已以较佳实施例揭露如上, 然而并非用以限定本发 明, 任何熟悉本专业的技术人员, 在不脱离本发明技术方案范围内, 当可 利用上述揭示的技术内容作出些许更动或修饰为等同变化的等效实施例, 但凡是未脱离本发明技术方案内容, 依据本发明的技术实质对以上实施例 所作的任何简单修改、 等同变化与修饰, 均仍属于本发明技术方案的范围 内。
