当控制器检测到 ACC和 Run由高电平变低电平或从 CAN/汽车通 用串行总线收到点火开关由 R u n, ACC状态变到定车状态, 控制器将 不输出电压驱动所有电机拖动遮阳布。
当控制器检测到 ACC 由低电平变高电平或从 CAN/汽车通用串行 总线收到点火开关处于 ACC状态,其将检测是否有 Rise button或 Down button有高电平。 Rise button 或 Down button有高电平表明有按键按下。 如 Rise button或 Down button的高电平持续短时间后, 即变为低电平, 控制器将输出电压驱动相应电机拖动前后挡风玻璃的遮阳布升降到最终 位置。如 Rise button或 Down button的高电平持续较长时间, 控制器将 输出电压驱动相应电机拖动前后挡风玻璃遮阳布, 直到 Rise button或 Down button变低电平为至或到达终点。当控制器检测到车门侧的上升 I 下降按键由低电平变高电平, 同时, 控制器从 C A N /汽车通用串行总 线读取到侧车窗处于完全升起状态, 控制器将输出电压驱动相应电机拖 动遮阳布, 根据按键的时间长短对遮阳布依前述方式控制。
当控制器检测到 ACC和 Run由低电平变高电平或从 CAN/汽车通 用串行总线收到点火开关由停车状态变到 R u n状态, 控制器将输出电 压驱动所有电机拖动遮阳布, 下降到终点, 完全露出车窗。 如有的遮阳 布已在完全下降位置, 电机将不再拖动。 在此状态下, 如收到侧后排两 车门上的上升 /下降按键由低电平变高电平, 同时, 控制器从 C A N / 汽车通用串行总线读取到车窗处于完全升起状态, 控制器将输出电压驱 动相应电机拖动遮阳布, 根据按键按下的时间长短确定。 上升 /下降的 位置。
在手动模式下, 当控制器从 CAN/汽车通用串行总线收到开门信号 或发动机启动信号, 控制器将不输出电压驱动任何电机拖动遮阳布, 遮 阳布将保持原状。
另外, 本发明还可以设置以下自诊断功能:
当系统出现故障, 微电脑将根据故障类型, 分配故障代码, 并存储 在微电脑内存中, 用户可通过 CAN/汽车通用串行总线读出故障代码, 方便系统的维护和修理。
本发明的遮阳布卷盒放置位置可以不同。 以上只是本发明的其中一 种实施例,即将其放置于前后挡风玻璃和车侧车窗的底部(如图 3所示)。 考虑不同车型的设计, 遮阳布卷盒可放置于前后挡风玻璃和车侧车窗的 底部或侧部。
