在一些实施方式中，多个挡位中存在用于指示行程位置对接于汽车的天窗的逃生挡位，以及，当行程挡位按钮105被操控至逃生挡位时，应急控制模块104还可以控制行程调节电机运动至用于指示逃生挡位对应的行程位置的目标行程位置。由此，当车辆因发生碰撞，腿部空间被占用且门被卡死时，可以通过行程挡位按钮将座椅调节至对接的天窗位置，使得驾驶员可以通过天窗逃生，增大紧急情况下的逃生机会。In some embodiments, among the multiple gears, there is an escape gear for indicating that the travel position is docked with the sunroof of the car, and when the travel gear button 105 is manipulated to the escape gear, the emergency control module 104 can also control The stroke adjustment motor moves to a target stroke position that is used to indicate the stroke position corresponding to the escape gear. Therefore, when the vehicle is in a collision, the leg space is occupied and the door is blocked, the seat can be adjusted to the docking sunroof position through the stroke gear button, so that the driver can escape through the sunroof, increasing the emergency situation Chance of escape.

本发明实施例利用控制单元响应于接收到车辆的碰撞信号，控制备用电源输出的备用电能输出至车辆的座椅前后调节电机，以驱动车辆的座椅进行行程调节，解决了车辆发生碰撞后驾驶室由于发动机侵入发生溃缩且智能车辆IG下电或蓄电池损坏情况下电动座椅无法向后调节造成驾驶员脱困空间狭窄的问题，防止由于车辆电动座椅无法调节造成驾驶员不能快速有效逃生的情况发生。In the embodiment of the present invention, in response to receiving the collision signal of the vehicle, the control unit controls the standby electric energy output by the standby power supply to be output to the front and rear seat adjustment motors of the vehicle to drive the seat of the vehicle to adjust the stroke, which solves the problem of driving after a vehicle collision. The room collapses due to engine intrusion and the power seat cannot be adjusted backwards when the smart vehicle IG is powered off or the battery is damaged, which causes the driver to get out of the trap and the space is narrow, preventing the driver from being unable to quickly and effectively escape due to the inability to adjust the vehicle power seat It happened.

The first relay is also connected to a backup power source. The control unit responds to receiving the vehicle collision signal and controls the first relay by sending a drive signal. The relay drives the MOS to work, thereby controlling the first relay to be turned on. Among them, a fuse can be connected between the backup power supply and the first relay, which can quickly cut off the backup power supply to prevent the occurrence of short circuit and other failure risks.

具体的，控制单元响应于控制第一继电器接通可为控制单元响应于向第一继电器驱动MOS发送驱动信号，与接收到车辆的碰撞信号时刻相比时间差较小，可忽略。Specifically, the control unit responds to controlling the first relay to be turned on, and the control unit responds to sending a driving signal to the first relay driving MOS, and the time difference is small compared with the moment when the collision signal of the vehicle is received and can be ignored.
可以理解，考虑到例如车辆碰撞导致安全气囊展开后，需一定的时间恢复，以便乘客脱困，因此需设置一预设时间，保证乘客处于安全可脱困情况后，再控制第二继电器接通。It can be understood that, considering that, for example, after a vehicle collision causes an airbag to deploy, it takes a certain time to recover so that the passengers can get out of the trap. Therefore, a preset time should be set to ensure that the passengers are in a safe and can be out of the trap before controlling the second relay to turn on.
其中，控制单元还用于：检测车辆的座椅的状态，座椅的状态包括：最大行程状态和卡滞状态；在车辆的座椅达到最大行程状态或卡 滞状态后，控制第一继电器断开，以使备用电源停止输出备用电能。Among them, the control unit is also used to: detect the state of the seat of the vehicle, the state of the seat includes: the maximum stroke state and the stuck state; after the seat of the vehicle reaches the maximum stroke state or stuck state, control the first relay to turn off Turn on to stop the backup power supply from outputting backup power.

After the control unit receives the motor feedback signal, it compares with the normal adjustment calibration data to determine the seat state. If the result of the judgment is that the seat cannot be adjusted to the predetermined position, the control unit controls the first relay to turn off, so that the backup power supply stops outputting backup power, and sends an alarm signal through the alarm module to remind the passenger seat system of a jam failure; When the motor feedback signal received by the unit is the stroke dead-point voltage signal, it is determined that the seat has completed the maximum backward stroke adjustment.

具体的，电源管理芯片、备用电源及车辆的IG电之间并联连接，控制单元检测IG电是否下电，若IG电未下电，则可直接使用IG电和备用电源驱动座椅电机向后最大行程调节座椅，为乘客提供足够的脱困空间。若控制单元检测到IG电断开，则控制单元发送通讯信号至电源管理芯片，电源管理芯片断开其与车辆的IG电的电连接，防止备用电源向其他控制器反向供电，此时只有备用电源为系统供电， 以自动执行座椅电机向后调节。Specifically, the power management chip, the backup power supply and the IG power of the vehicle are connected in parallel, and the control unit detects whether the IG power is powered off. If the IG power is not powered off, it can directly use the IG power and the backup power source to drive the seat motor backwards. The maximum stroke adjustment seat provides enough space for passengers to escape. If the control unit detects that the IG power is disconnected, the control unit sends a communication signal to the power management chip, and the power management chip disconnects its electrical connection with the IG power of the vehicle to prevent the backup power supply from supplying reverse power to other controllers. At this time, only The backup power supply supplies power to the system to automatically perform the rear adjustment of the seat motor.
此外，电源管理芯片还用于根据备用电源和/或IG电输出的电能为控制单元提供其所需的稳定电流。In addition, the power management chip is also used to provide the control unit with the required stable current according to the power output from the backup power supply and/or IG electricity.

The waterproof connector can be sealed and waterproofed with IPX7 to prevent the battery pack from being immersed in water and short-circuited. When the smart vehicle is driving normally, the backup power supply can be automatically charged, and the charging power supply will be automatically cut off after being fully charged. The fuse of the backup power supply is located inside the protective shell. After the fuse is disconnected, the current at the connector of the shell will be completely cut off to prevent short circuits.

The two relays are turned on, so that the backup electric energy output by the backup power supply is output to the front and rear adjustment motors of the vehicle seat. Compared with the prior art, when the IG is powered off and the seat adjustment motor cannot be driven to adjust the seat, the embodiment of the present invention can control the relay to drive the seat adjustment motor through the main control MCU of the vehicle, and cooperate with the sensor at the same time. Cooperate with the signal receiving module to automatically adjust the seat system without human intervention, providing sufficient escape space for the driver or front passenger after a smart vehicle collision. In addition, the emergency relief module automatically cuts off the system power after completing the emergency adjustment operation to prevent other accidents.
另外，座椅控制器由IG电提供的电能D+供电，当智能汽车发生碰撞后，在碰撞加速度达不到座椅域控制器和应急脱困模块抗冲击极 限的情况下，碰撞信号会在短时间(毫秒级)内传递到应急脱困模块内。该过程在碰撞瞬间完成，蓄电池损坏或IG下电的情况均发生在应急脱困模块接收到碰撞信号后。然后应急脱困模块响应于接收到车辆的碰撞信号控制其内部的备用电源输出的备用电能输出至车辆的座椅前后调节电机，以驱动车辆的座椅进行行程调节。霍尔传感器用于提供电机反馈信号，从而确定座椅电机运行情况，判断是否完成调节和电机是否卡滞。In addition, the seat controller is powered by the electrical energy D+ provided by IG. When the smart car crashes, if the collision acceleration does not reach the impact resistance limit of the seat domain controller and the emergency escape module, the collision signal will be in a short time. (Milliseconds) to the emergency escape module. The process is completed at the moment of the collision, and the battery damage or the IG power off all occur after the emergency escape module receives the collision signal. Then the emergency escape module responds to the collision signal received from the vehicle and controls the backup power output from its internal backup power supply to output to the front and rear seat adjustment motors of the vehicle to drive the seat of the vehicle for stroke adjustment. Hall sensors are used to provide motor feedback signals to determine the seat motor's operating conditions, to determine whether the adjustment is completed and whether the motor is stuck.

Specifically, the collision signal is transmitted to the seat area controller through the CAN bus, where CAN-L is the low-level data line, and CAN-H is the high-level data line.
