With the development of the electronization and the intellectualization of automobiles, the comfort of the automobiles is higher and higher, for example, the one-key automatic lifting function of windows becomes a necessary configuration for most automobile models. The whole vehicle can improve the comfort and simultaneously consider the safety of the function, and if the power window is required to have a certain anti-pinch function. The car window is prevented pressing from both sides and is an important component of car humanized design, and its main function is after the car window rises to the centre gripping object, can discern that the car window is in the clamping state to make the car window roll back and release the centre gripping object, prevent that window motor stall for a long time from leading to burning out, and prevent that vehicle passenger from being hindered by the clamp.
At present, the anti-pinch function of the electric vehicle window mainly comprises two schemes of Hall anti-pinch and ripple anti-pinch. Compare hall and prevent pressing from both sides technique, prevent pressing from both sides technical cost more excellent based on ripple current, only have the hall about and prevent 1/2 that press from both sides, this just makes the door window prevent pressing from both sides the function and promote by a wide margin at passenger car field configuration rate.
At present, most of ripple anti-pinch modules in the market are independent modules, and the anti-pinch control function of four-door car windows is realized by an independent ripple anti-pinch module. Information interaction is carried out between ripple anti-pinch module and four door window switches through the hardwire, and the window motor work of driving by the controller again. Therefore, the wiring harness layout of the whole vehicle is complex, the space in the vehicle occupies a large space, and the weight and the cost of the whole vehicle are increased. In addition, the ripple current acquisition circuit of the car window motor is far away from the car window motor, so that the accuracy of the acquired current ripple is insufficient, and the system is easy to prevent mistaken clamping; moreover, one controller controls four window motors, the functional requirement on the controller (namely MCU) is high, only few supplier resources exist at present, and potential risks exist in material conservation.
