Car window anti-pinch detection method and device, storage medium and car
The invention discloses a car window anti-pinch detection method and device, a storage medium and a car. In the motor loading process, a reference current threshold value is determined based on the obtained current motor voltage, and a current motor direct current component is determined based on the obtained current motor current; calculating a current motor direct-current component mean value of continuous N sampling periods until the current moment, and solving the difference between the current motor direct-current component mean value and the motor direct-current component mean value at the previous moment to obtain a direct-current component mean value difference, and compensating the reference current threshold value based on the magnitude relationship between the direct current component mean value difference and the direct current component mean value variation of different levels to obtain a target current threshold value, and controlling the car window to descend when the current motor direct current component is not smaller than the target current threshold value. The current threshold value is dynamically updated according to the motor voltage and the motor current which are collected in real time in the motor loading process, the accuracy of anti-pinch detection in the motor starting process is improved, and the situations that a car window is prevented from being pinched by mistake and the clamping force of the car window is too large are effectively avoided.
