The controller according to claim 2, wherein the acquisition unit is further configured to acquire obstacle distance information acquired by an anti-collision radar, and the control unit determines whether an actual distance between the vehicle door and an obstacle is smaller than a preset threshold according to the obstacle distance information, and controls the driving unit to stop driving the actuator corresponding to the vehicle door when the actual distance is smaller than the preset threshold.
4. A controller according to claim 3, further provided integrally with a communication unit, wherein,
the communication unit is used for communicating with any input device and forwarding the vehicle door control command, the vehicle window control command, the input signal of the position sensor of the stopper and the obstacle distance information which are input by any device to the acquisition unit.
5. The controller of claim 2, further provided integrally with a memory unit, wherein,
the storage unit is used for storing the input signal of the position sensor of the position limiter, the input setting of a user and the opening angle and speed of the user.
6. A controller according to claim 1, wherein the controller is further provided integrally with a diagnostic unit, wherein,
the diagnosis unit is used for diagnosing whether the driving current, the driving voltage and the ripple wave are in corresponding preset ranges when any actuating mechanism is driven, judging faults of the corresponding actuating mechanism when the driving current, the driving voltage or the ripple wave are not in the corresponding preset ranges, and outputting fault alarm prompts.
7. The controller of claim 1, further integrally provided with a power management unit, wherein,
and the power supply management unit is used for controlling the on-off of a power supply circuit of any unit in the controller.
8. An integrated control system for a vehicle door and a vehicle window, comprising:
the actuating mechanism of any vehicle door and the actuating mechanism of any vehicle window;
the integrated controller of the vehicle door and the vehicle window as claimed in any one of claims 1 to 7, configured to control an actuator driving a corresponding vehicle door according to the vehicle door control command, so as to control the corresponding vehicle door to be in a preset opening state or a preset closing state, and/or drive the actuator of the corresponding vehicle window according to the vehicle window control command, so as to control the corresponding vehicle window to ascend or descend to a first preset position.
9. The system of claim 8, wherein,
the actuating mechanism of any vehicle door comprises a limiter motor, an electromagnetic damper, a vehicle door central locking motor and a vehicle door suction locking motor;
the actuating mechanism of any vehicle window comprises a vehicle door lifter motor.
10. An integrated control method for a vehicle door and a vehicle window, which is applied to the integrated controller for the vehicle door and the vehicle window according to any one of claims 1 to 7, and comprises the following steps:
acquiring a vehicle door control instruction of any vehicle door and a vehicle window control instruction of any vehicle window;
and controlling the driving unit to drive the executing mechanism of the corresponding vehicle door according to the vehicle door control instruction so as to control the corresponding vehicle door to be in a preset opening state or a preset closing state, and/or controlling the driving unit to drive the executing mechanism of the corresponding vehicle window according to the vehicle window control instruction so as to control the corresponding vehicle window to ascend or descend to a first preset position.
