Design of anti-clip calibration system for car sunroof based on Hall pulse width
In order to solve the problem that traditional anti-clip system has low adaptability to the actual driving environment and the algorithm parameters are difficult to be determined,a kind of anti-clip calibration system for automobile sunroof based on Hall pulse width is designed.Hall sensor is used to monitor the running state of sunroof motor,and anti-clip function is triggered according to the approximate proportional relationship between Hall pulse width and clamping force.At the same time,Kalman filter and pulse width integration algorithm are used to reduce the false anti-clip operation caused by noise.Universal calibration system for vehicle field is established by calibration protocol based on CAN bus.The actual parameter values of anti-clip algorithm under different power supply voltages and road surface conditions are calibrated by experiments,and good anti-clip effect is achieved,which meets the requirements of the anti-clip system for environment.
