智能汽车平衡检测装置 技术领域
本发明涉及智能汽车领域， 更具体的说是涉及一种智能汽车平衡检测装 置。
背景技术
汽车自上个世纪末诞生以来， 已经走过了风风雨雨的 100多年。 歩入 21 世纪， 随着科学技术的不断发展和生活水平的提高， 人们对汽车的安全性和 舒适性要求越来越高， 各种先进技术， 被应用和研究， 使得汽车工业又迎来 了新的挑战和革命。 2005年美国 《汽车新闻》、 《汽车工程》等杂志对未来汽 车技术发展的十大趋势预测表明： 下一个汽车销售高潮将从普及 "智能化汽 车"开始。汽车的智能化是大势所趋。 在智能汽车领域， 要实现汽车的跟驰， 其汽车的平衡时至关重要的部分之一， 若汽车不平衡， 汽车在跟驰驾驶时， 易发生交通事故， 譬如汽车侧翻， 给汽车行驶带来安全隐患。
发明内容
本发明提供一种智能汽车平衡检测装置， 其对汽车的平衡进行检测， 当 汽车在跟驰中失去平衡， 即告警， 保证汽车安全行驶。
为解决上述的技术问题， 本发明采用以下技术方案：
智能汽车平衡检测装置， 它包括方向传感器、 加速度传感器、 控制器和 四个分别设置于四个车轮上的称重传感器， 称重传感器、 方向传感器和加速 度传感器均连接在控制器上， 所述的控制器上还连接有告警装置。
更进一歩的技术方案是： 作为优选， 所述的称重传感器为数字式称重传感器。
作为优选， 所述的方向传感器设置于汽车的转盘上。
作为优选， 还包括速度传感器， 所述的速度传感器连接在控制器上。 作为优选， 所述的告警装置为蜂鸣器。
作为优选， 所述的控制器为 MSP430。
与现有技术相比， 本发明的有益效果是：
本发明利用称重传感器对汽车的平衡进行检测， 当汽车在跟驰中失去平 衡， 即告警， 保证汽车安全行驶。
附图说明
下面结合附图和具体实施方式对本发明作进一歩详细说明。
图 1为本发明的原理框图。
具体实施方式
下面结合附图对本发明作进一歩的说明。 本发明的实施方式包括但不限 于下列实施例。
[实施例]
如图 1所示的智能汽车平衡检测装置， 它包括方向传感器、 加速度传感 器、 控制器和四个分别设置于四个车轮上的称重传感器， 称重传感器、 方向 传感器和加速度传感器均连接在控制器上， 所述的控制器上还连接有告警装 置。 称重传感器安装固定在汽车的四个车轮上， 分别对四个车轮的承重状况 进行检测，方向传感器和加速度传感器分别对汽车的方向和加速度进行检测。 当四个称重传感器检测到四个车轮的承重情况的数据不一致时， 控制器根据 方向传感器和加速度传感器检测的数据来进行判断汽车是否处于不平衡的状 态， 以控制告警装置开始报警。举例来详细说明： 当汽车在一条直线上行驶， 即方向传感器检测到汽车的行驶方向为汽车的正前方， 此时， 若四个车轮的 承重状况不相同， 此时， 控制器判断汽车不平衡， 则控制告警装置开始告警。 当汽车处于转弯或者换道行驶时， 即方向传感器检测到汽车的行驶方向与车 身方向不在一条直线上， 此时， 控制器根据方向传感器检测的汽车行驶的方 向和加速度传感器检测的汽车状态， 即偏移的角度和加速度大小， 来判断汽 车的平衡状态， 若汽车处于正常的转弯或换道状态， 则汽车正常行驶， 若判 断汽车处于不平衡状态， 则控制告警装置开始告警， 提醒人注意， 或替换为 人为驾驶使车停驶， 以对车辆状况进行检査， 保证行车安全。
为了便于控制器对数据进行处理， 所述的称重传感器为数字式称重传感 器。 数字式称重传感器对车轮的承重状况进行检测， 其数据传输距离远， 抗 干扰能力强、 具有唯一的标记、 多只传感器并联后可分别检测每个传感器的 状态、 便于故障诊断。 且数字式称重传感器检测的结构为数字式， 其结构直 接传输给控制器， 便于控制器的处理， 也简化了处理电路。
所述的方向传感器设置于汽车的转盘上。 方向传感器用于对汽车的行驶 方向进行检测， 由于转盘控制汽车的行驶方向， 将方向传感器设置在汽车的 转盘上， 便于直接对汽车的行驶方向进行检测。
还包括速度传感器， 所述的速度传感器连接在控制器上。 速度传感器用 于对汽车的行驶速度进行检测， 可增强本发明对平衡的检测准确度。 利用速 度传感器对汽车的速度进行检测， 当车辆处于低速状态， 譬如倒车、泊车时， 控制器对平衡状态的误判。
所述的告警装置为蜂鸣器。 通过蜂鸣器的鸣叫对司机以提醒， 达到提醒 司机注意的目的。
所述的控制器为 MSP430。 利用 MSP430做控制器， 其灵敏度高， 可提 高整个装置的可靠性。
如上所述即为本发明的实施例。 本发明不局限于上述实施方式， 任何人 应该得知在本发明的启示下做出的结构变化， 凡是与本发明具有相同或相近 的技术方案， 均落入本发明的保护范围之内。
