Abstract
The utility model discloses a be applied to controlgear of car door, including voltage/current signal processing circuit module, motor formula door lock module, the voltage/current signal processing circuit module include signal detection device, signal separation device, motor formula door lock module include controller and motor, electric machine control car door lock atress module, the signal separation device become two passageways with signal separation, send into respectively among two parallelly connected motor formula door lock module, one of them motor formula door lock module is equipped with the velocity compensator, velocity compensator received signal from the signal separation ware to send a signal to the controller, the motor is connected to the controller, speed signal transfer to the signal detection device and the controller of motor.
Description
Technical field
This utility model relates to the technical field of bi-motor Synchronization Control arrangements for automotive doors state, it is a kind of state based on current detection technology in electric system (current sensor) method detection arrangements for automotive doors in particular, if automobile detects that arrangements for automotive doors is in not closed state on startup, then the control of Guan Bi arrangements for automotive doors of being had an effect by load quickening motor speed.
Background technology:
Currently, along with the further development of Chinese society's economy with science and technology, the Automobile Market of China is also greatly increased, and also becomes one of automobile production state of maximum in the world simultaneously.In order to improve China's automobile product competitiveness in the world market it is necessary to improve product technology.The safety of arrangements for automotive doors Guan Bi is also a most critically important link, it is possible to the personal safety of guarantee driver and by bus member.There is stronger practicality.
Utility model content
The purpose of this utility model be for automobile driver and by bus member one safety is provided use car environment, it is to avoid the unnecessary danger caused because of vehicle gate ajar when driving.
The system schema that this utility model is used is: a kind of control equipment being applied to arrangements for automotive doors, including current signal processing module, electric motor type door lock module；Described current signal processing module includes that signal supervisory instrument, signal separator, described electric motor type door lock module include that controller and motor, described motor control car door lock stress module；Described signal separator separates the signal into two passages, is respectively fed in two electric motor type door lock modules of parallel connection；One of them electric motor type door lock module is provided with velocity compensator, and described velocity compensator receives signal from demultiplexer, and sends a signal to controller, and controller connects motor；The rate signal of motor is sent to signal supervisory instrument and controller.
Preferably, described signal supervisory instrument completes signal detection by current sensor.
Its operation principle is as follows: current signal processing module is that the circuital current of method based on current detection technology (current sensor) detection automobile arrangements for automotive doors functional module on startup the most normally works.When electric current passes through a conductor being positioned in magnetic field when, magnetic field can produce an active force being perpendicular on electron motion direction to the electronics in conductor, thus in the voltage difference of the two ends of conductor generation.
The Signal separator fed back in current signal processing module is become two passages by signal separator, and the signal after separation is sent in two electric motor type door lock modules in parallel.Controller in electric motor type door lock module regulates the input of controlled volume according to the deviation (deviation and deviation variation rate here refer to the speed between two motors and percentage speed variation) of setting value and measured value, thus regulate the rotating speed of motor so that it is in the range of error required.
The work process of the electric motor type door lock module being provided with compensator is: if the signal of detection is normal signal, then velocity compensator does not starts, and directly exports.If detecting, signal is not in normal condition, then toggle speed compensator, is increased the rotating speed of motor by backoff algorithm, makes motor control car door lock stress Guan Bi.
Now, the rotating speed of another electric motor type door lock module is ensured rated speed by controller.The speed difference that two motor feedbacks are returned is poor, i.e. the deviation of motor 1 deducts the deviation of motor 2, obtains a deviation value, then carries out PID regulation, is that arrangements for automotive doors circuit returns normal operating conditions.When deviation is fed back to motor, motor 1 is positive feedback, and motor 2 is negative feedback.Make arrangements for automotive doors circuit return normal duty, be in locked state to prevent car door lock from being had an effect by motor, and then the safety of protection occupant.
In sum, this utility model advantage is as follows: this utility model uses the mode of current detection technology, it is possible to accurately effectively detect that arrangements for automotive doors circuit module the most normally works.Synchronizing system deviation coupling PID control in conjunction with using bi-motor, system has higher synchronization accuracy, improves the trace performance of motor, enhances the robustness of system, and has taken into account rapidity and the requirement of stability of system response.

Fig. 1 is principle schematic of the present utility model；
Fig. 2 is that bi-motor synchronizes system deviation coupling control structure figure.
