Abstract

The invention discloses a control system and method of a car window. The system comprises a car window motor drive circuit, a key sampling circuit, a ripple sampling circuit, a power circuit and a carwindow ripple anti-pinch controller; the car window ripple anti-pinch controller comprises a processor, an operational circuit used for collecting motor lifting current value and a detection circuitused for detecting the number of motor current ripples, the ripple sampling circuit comprises a sampling resistor arranged at the powering-on end of a car window motor, the car window ripple anti-pinch controller is connected with the key sampling circuit, the ripple sampling circuit and the output end of the power circuit. Compared with an existing car window control system, the system has the beneficial effects that the automation degree and the user-friendly degree are higher, the anti-pinch performance is more stable and reliable, and the effect can be effectively improved.

Description

technical field [0001] The invention relates to the field of automobile window control, in particular to an automobile window control system and method. Background technique [0002] At present, China's automotive electronics market is developing very rapidly, and it is also a key point in the development of the automotive industry. With the advancement of modern automotive electronics technology, traditional parts and assemblies in automobiles are also developing towards mechatronics. A large number of electronic devices used in automobiles not only improve the comfort of automobiles, but also put forward new requirements for automobile safety. For the convenience of drivers and passengers, a large number of automobiles use electric windows, many of which do not have an anti-pinch function, which is likely to cause injuries to occupants, especially children. For safety reasons, it is absolutely necessary to develop a window control with anti-pinch function. Although China...
