Description

油门踏板信息回馈系统 技术领域
本发明涉及一种通过油门踏板将动力系统的负荷状态信息回馈给驾驶的系统，具体而 言， 涉及一种利用传感器收集系统运行信息， 并以电脑程序计算出车辆动力系统的负荷状 态， 并依据负荷状态信息调整油门踏板阻力， 以将该信息提供给驾驶人的信息回馈系统。 该系统主要应用于使用电动机驱动的大型车辆。 背景技术
电动车辆与内燃引擎车辆相比， 最大的优势为低噪音及低震动。 正常来说， 当驾驶人 在驾驶传统内燃引擎车辆时，可经由引擎的震动及噪音得知引擎的负荷状况及运行是否正 常。 电动车辆的低噪音及低震动特性使得驾驶人无法通过相同方式得知车辆的运行状况， 使得电动车辆因超载或过热等原因而发生故障的机会增加。 虽然车上配有仪表， 但若路况 较拥挤或是驾驶时间较长， 驾驶人很容易忽略仪表上所提供的讯息。 发明内容
传统内燃车辆在运行时会产生震动及噪音，而该震动及噪音的特征与动力系统的负荷 状态相关， 因此驾驶者可经由感觉车辆的震动及噪音即时得知车辆动力系统的负荷状态。 当使用电动车辆取代内燃车辆时， 由于动力系统的振动及噪音大幅减少， 导致驾驶者无法 得知动力系统的负荷状态， 而容易使动力系统长时间在高负荷状态下运转， 进而导致过热 及过载。 虽可让系统自行依照负荷状态进行限流保护， 但会导致驾驶者输入的指令与车辆 实际输出动力脱节， 导致驾驶者疲劳及对车辆产生不信任感； 此状况发生在急需大动力输 出的紧急情况时， 极有可能因动力被限制而导致意外发生。
基于已知电动大型车的动力系统， 易因长期处在高负荷状态下而导致过热的问题， 本 发明旨在提供一种完善的系统负荷信息回馈机制， 有效的将系统的负荷信息传达给驾驶 者， 以解决电动大型车辆因不当操作而长期处在高负荷状态下导致过热的问题。
本发明的目的在于：
一、 提供一种不影响驾驶者对周遭环境注意力的系统负荷状态回馈机制。
二、 提供一种将系统的负荷状态即时回馈给驾驶者的机制。

104 第一弹簧
105 第二弹簧
106 预压器
107 预压调整机构 具体实施方式
本发明涉及一种为了有效解决以下状况的系统负荷状态回馈系统：
一、驾驶者欲得知系统的负荷状态时需将注意力放在仪表台， 导致驾驶在该时段无法 保有对周遭环境的注意力。 已知的动力系统信息显示大多为设于驾驶台上的仪表， 当驾驶 者欲得知系统的负荷状态时， 必须将视线由路面转到驾驶台上， 导致驾驶者短暂失去对路 况的注意力。 若在该时段内发生紧急状况， 有可能延误处理时机并导致事故。
二、 驾驶者所得知的系统负荷状态信息并非直观， 导致驾驶者需要去花时间及专注力 去解读获得的信息。 已知的动力系统信息显示方式主要为数位或指针， 在驾驶者接收到这 些讯息时， 往往需耗费脑力去解读接收到的信息； 更进一步地， 经常将视线在路面及驾驶 台之间转换也易产生驾驶者眼部疲劳， 连带影响专注力。
三、 当系统负荷状态警示功能发生故障时， 易影响驾驶者对车辆的操控及专注力。 已 知的动力系统过载警示经常以闪光或声响提醒驾驶者过载的情况，若传感器发生故障而导 致系统误判， 持续的闪光或警示声响易影响驾驶的专注力及情绪， 也易引起乘客恐慌。
四、当系统处于超载状态时，系统的限流保护易导致驾驶失去对车辆的绝对操控能力， 导致危险的发生。 已知的动力系统过载保护方式是由控制系统自行对输出电流做限制， 以 减少车辆输出动力的方式避免动力系统过载。若驾驶者在急需动力以避免事故的情况下遇 到过载保护， 有可能造成驾驶者无法准确的操控车辆， 而导致事故的发生。
为了有效解决上述状况所导致的问题，本发明提供一种油门踏板系统负荷状态信息回 馈系统。 根据本发明的一种实施例， 所述油门踏板系统负荷状态信息回馈系统包括： 可控 制阻力的油门踏板机构、 数个系统状态传感器、 及控制单元。 其中可控制阻力的油门踏板 机构还包含： 踏板底座、 踏板本体、 踏板角度传感器、 固定弹性元件、 可调弹性元件及可 调弹性元件调整机构。
该数个系统状态传感器主要用于感测动力系统的负荷状态， 如： 马达温度、 马达驱动 器温度、 电池温度、 冷却系统温度及电池充电状态信息， 并将信息提供给控制单元。 控制 单元将利用系统状态传感器所提供的信息决定踏板阻力，并指示该油门踏板机构做出相应 的调整。 请参阅图 1及图 2， 所述附图分别示出了根据本发明第一实施例的油门踏板信息回馈 系统及控制方法。 底座 101 用于与车身结构结合， 并提供一稳固的基座。 踏板 102 与底 座 101 以一轴心结合， 并可以该轴心为转轴转动。 角度传感器 103 与踏板 102 及底座 101 结合， 用以感测踏板 102 与底座 101 间的角度； 该角度传感器 103 用于提供踏板 102 的移动量给动力系统。
第一弹簧 104 用于提供踏板 102 稳定的阻力。
第二弹簧 105 与踏板 102 之间留有一特定距离。 在踏板 102 的移动量小于该特定 距离在第一活动范围内时， 踏板 102 将不与第二弹簧 105 接触， 踏板 102 只由第一弹 簧 104 提供阻力。在踏板 102 的移动量超过该特定距离在第二活动范围内时， 踏板 102 将与第二弹簧 105 接触， 并由第一弹簧 104 及第二弹簧 105 同时对踏板 102 提供阻 力。
预压器 106 会对第二弹簧 105 进行预压， 该预压会增加第二弹簧 105 对踏板 102 所施加的阻力。预压调整机构 107 可接受控制单元的指令， 并调整预压器 106 对第二弹 簧 105 的预压量， 以改变第二弹簧 105 对踏板 102 所施加的阻力。
本实施例亦同时包含一控制方法。在车辆启动时， 会依照下列步骤控制该预压调整机 构 107：
步骤一： 系统进入一自检状态， 确认各个传感器是否正常运行。
步骤二： 数个系统状态传感器将动力系统负荷状态信息提供给控制单元。 该动力系统 负荷状态信息包括： 马达温度、 马达驱动器温度、 电池温度、 冷却系统温度及电池充电状 态。
步骤三：控制单元利用动力系统负荷状态信息计算出踏板阻力，并以第二弹簧 105 的 参数计算出相对应的预压量。
步骤四： 将该预压量转换成一控制指令， 并将该指令传达给预压调整机构 107， 以改 变预压器 106 对第二弹簧 105 所施加的预压量。
步骤五： 在第二弹簧 105 的预压量调整后， 此控制方法完成， 并等待下次启动。 本实施例所披露的控制单元在避免动力系统因不当操作造成过载的同时，还可利用其 他车辆相关信息以提升行车安全或能源使用效率。该车辆相关信息包括：车重、路段限速、 驾驶者持续行驶时间、 与前方车辆的距离及电池充电状态。
本实施例所披露的构思可有效解决先前已叙述的情况， 并达成下列功效：
一、驾驶者在行驶期间可通过油门踏板的阻力得知系统的负荷状态， 可免去驾驶者将 注意力从路面转移到驾驶台的需求及连带的风险。
二、 驾驶者可以很直觉的通过油门踏板的阻力去得知系统的负荷状态， 免去解读数据 或指针位置的需求； 相较于需要思考的数据或指针位置， 透过腿部肌肉所感觉到的油门阻 力更可即时的将系统的负荷状态信息传达给驾驶者。
三、 若此系统发生故障， 只会影响第二弹簧对踏板所施加的阻力， 并不会影响驾驶者 对车辆的控制能力， 也不会产生易影响驾驶的闪光或声响。
四、此信息回馈系统在动力系统处于高负荷状态的时候， 只会增加第二弹簧对踏板所 施加的阻力， 并不会对动力系统输出施加限制。若驾驶者需要车辆大幅输出动力以避免意 外发生， 只需用力将踏板踩下， 动力系统依然会依照踏板的移动量提供动力输出。
