电动车窗（Power window） Design of automobile power window control circuit 2010-05-26 15:20:14 source: internet keyword: car window control, clip automotive electronics In the design of a new car model of Hunan Changfeng automobile manufacturing Limited by Share Ltd, according to the definition of the whole car, the electric vehicle window adds the automatic closing window function and the anti pinch function on the basis of the basic vehicle model. At the same time, it is necessary to use the spare parts of the base vehicle as much as possible during the design process, which can save development time and reduce cost. In this paper, the new type of power window control circuit is designed, and the design of the new type of power window control circuit is solved. 1. basic car electric window control circuit The new model design, not everything from scratch, but first of all, according to the design requirements, select a basic model as a reference, this can reduce design difficulty, so that design ideas more clearly. The new type of power window design is also based on reference models, power windows, therefore, it is necessary to introduce the basic type of electric car window function and control principle and method. The utility model relates to an electric window control mechanism of a base type vehicle, comprising an electric vehicle window main switch, an electric vehicle window vice switch, an electric window motor, an electric window motor and a circuit breaker. Schematic diagram of power car windows for basic models shown in figure 1. In Figure 1, the ignition switch is located in the ON position, the power window relay is closed, the voltage of the battery through the fusible wire electric window control circuit of the power supply to the 10. When you press the power window? The main point or side? Snow switch (UP or DOWN) when the current flows to the power window motor through the fuse no.. As a result, the electric window motor is rotated to obtain electrical
