Anti-pinch circuit, anti-pinch circuit device and anti-pinch circuit method for positioning ripple waves of vehicle window precisely and vehicle
The invention relates to the field of vehicle electronic control, in particular to an anti-pinch circuit, an anti-pinch circuit device and an anti-pinch circuit method for positioning ripple waves ofa vehicle window precisely and a vehicle. The circuit comprises a driving current collecting module and a control module, wherein the driving current collecting module is used for collecting a drivingcurrent of a vehicle window motor; and the control module is used for acquiring the value of the driving current and the quantity of the ripple waves to judge the position of vehicle window glass, and the control module is configured to control a vehicle window motor to stop rotating when the position belongs to a preset stopping area and to control disconnection of the driving current collectingmodule and the vehicle window motor within a preset time after the vehicle window motor stops rotating. After the vehicle window motor stops, the control module controls disconnection of the drivingcurrent collecting module and the vehicle window motor, so that a relay is resilient to not affect the wave form the ripple wave current in the disconnection process, and therefore, the positioning precision and reliability of the ripple wave anti-pinch module are improved.
本申请涉及车辆电子控制领域，特别是涉及一种精确定位车窗纹波防夹电路、装置、方法和车辆，所述电路包括：驱动电流采集模块，用于采集所述车窗电机的驱动电流；控制模块，用于获取所述驱动电流的值及纹波个数以判断车窗玻璃的位置，所述控制模块被配置为：当所述位置属于预设的停止区域时，控制所述车窗电机停止转动，以及在所述车窗电机停止转动之后预设的时间内，控制断开所述驱动电流采集模块与所述车窗电机的连接。本申请在车窗电机停止之后,所述控制模块控制断开所述驱动电流采集模块与所述车窗电机的连接，使得断开连接过程中的继电器回弹不会对纹波电流的波形产生影响，从而提高了纹波防夹模块的定位精度与可靠性。
