Abstract
The utility model relates to an anti-pinch device of an electric window which is based on the self-adaptability, including a controller unit part, a driving circuit of the electric window and a LIN bus interface circuit which are connected sequentially, and the driving circuit of the electric window is connected with a motor to drive the electric window. The utility model further provides a control method of the anti-pinch device of the electric window which is based on the self-adaptability, the utility model can continuously extract the necessary parameters of judgement of a control system to realize the anti-pinch at the same time of detection of the current of the electric window and continuously modify the parameters of judgement. The utility model can improve the control system continuously, so the control function which is based on the control system can be improved continuously accordingly. Thus, the control system has the certain capacity of self-adaptability, and the utility model can be applicable to the dynamic specific changes of the different vehicle types and the different vehicle electric windows of the same type by the continuous correction of the control parameters.
Description
Technical field
The utility model relates to a kind of vehicle servicing unit, and is specifically a kind of based on adaptive power windows finger pinch device.
Background technology
The control object of power windows control module is exactly a power supply 11V-15V, and operating current is not more than 15A, and locked rotor current is not more than the permanent magnet DC motor of 28A.Once the door device of controlling with mechanical means made Electronic Control now gradually in the past, and increasing low side automobile also begins to adopt electronically controlled door control system, utilized the communication between four car doors of bus communication technology realization.For the sake of security, now a lot of passenger cars have all adopted electronic anti-pinch vehicle window.Existing electronic anti-pinch vehicle window all is Hall element to be installed come induction machine whether to be subjected to resistance on the motor of glass-frame riser, the sensing of other optics perhaps has been installed, but this motor needs specially treated, and the motor of present most of glass-frame riser all is a common electric machine.According to the electrical characteristic of direct current generator, the variation of the electric current that the lifter motor passes through reflects the resistance transfer situation that runs in the glass process of rising or falling.Thereby, can realize the anti-tong function of power windows fully by the electric current situation of change of analyzing the lifter motor.But the vehicle window of various vehicle is different in the electric current situation of change of running mid-riser motor; The vehicle that same vehicle is different may increase a lot of external disturbance, thereby the electric current situation of change is different.
Summary of the invention
The utility model is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of can adapt to different automobile types, the dynamic specific change of same model different vehicle power windows based on adaptive power windows finger pinch device.
The purpose of this utility model is to adopt following technical proposals to realize:
A kind of based on adaptive power windows finger pinch device, comprise controller unit part, power windows drive circuit, LIN bus interface circuit, LIN bus interface circuit, controller unit part are connected successively with the power windows drive circuit, and the power windows drive circuit links to each other with the motor that drives power windows.
Described controller unit part is responsible for communicating by letter with the LIN communications portion, and is sent motor control signal; Change by ND and to detect the vehicle window current of electric, adopt adaptive algorithm to realize anti-tong function.
Described power windows drive circuit is the intelligent power driver module, is responsible for receiving the control signal of motor, and drive motors, the current signal of the Car window electric machine of sampling simultaneously.
