Automobile electric tailgate stay bar anti-clamping control system based on Hall sensor
The invention discloses an automobile electric tailgate stay bar anti-clamping control system based on a Hall sensor. The system comprises a central processing unit, a CAN signal transceiving unit with a signal transceiving function, a CAN bus for receiving vehicle information and a tailgate stay bar device, wherein the central processing unit is connected with the tailgate stay bar device; the tailgate stay bar device comprises the Hall sensor used for detecting the rotating speed of a stay bar motor, when the tailgate meets an obstacle when being opened or closed, when the rotating speed ofthe stay bar motor falls below a set limit, the Hall sensor detects the existence of an obstacle, meanwhile, the current consumption of the stay bar motor is increased, the power supply of the stay bar motor is reversed, so that the trunk cover moves in the opposite stroke direction. The system has the functions of intelligently detecting obstacles and realizing emergency braking, and the tailgatecan be automatically retracted when encountering obstacles when the tailgate is opened, so that the stay bar motor is prevented from being burnt due to excessive current; when the tailgate is closed,the tailgate can automatically bounce back when encountering obstacles, and accidental clamping injury is avoided.
本发明公开了一种基于霍尔传感器的汽车电动尾门撑杆防夹控制系统，包括中央处理单元、具有信号收发功能的CAN信号收发单元、用于接收车辆信息的CAN总线和尾门撑杆装置，中央处理单元与尾门撑杆装置连接，尾门撑杆装置包括用于检测撑杆电机转速的霍尔传感器，当尾门在开启或关闭遇到障碍物时，撑杆电机转速下降至设定的限度以下，则霍尔传感器探测到障碍物的存在，同时撑杆电机电流消耗增加则对撑杆电机的电源供应会反向进行从而导致行李箱盖按相反的行程方向运动。本发明具有智能检测障碍物并实现紧急制动的功能，当尾门开启时遇到障碍物能自动收回，避免因电流过大烧坏撑杆电机；在闭合时遇到障碍物能自动弹回，避免意外夹伤。
