Because of adopting the circuit structure aforementioned, the control system has the following advantages that 1, the normal use of the window is not influenced while the anti-pinch function of the power window is reliably ensured; 2, via the combination of a current and a speed, and adoption for an adaptive algorithm, the thresholds of the current and the speed are updated in real time, thus avoiding false anti-pinch; and 3, the current flowing through a motor can be randomly controlled, so that the control system is strong in universality.
Description
Technical field
The utility model relates to automobile manufacturing field; Be particularly related to a kind of electric vehicle window of vehicle and control system.
Background technology
Along with constantly popularizing of automobile, the security performance of automobile more and more comes into one's own.Power windows with automobile is an example, and the power windows with pinch resistant functionality is applied on the increasing vehicle.
For the reliability that improves pinch resistant functionality in the glass for vehicle window uphill process motor is carried out constant current control in the prior art, after folder people accident took place, the maximum power output of also having only 100N can guarantee safety and the probability that reduces wrong anti-pinch.But the feedback circuit that wherein constant current is leaned on is to use amplifier, resistance to form realizes, can not real-time regulated; Current value can only reflect the level of torque of motor output, and can not reflect the size of glass to the chucking power of obstruction.When just dispatching from the factory, it is 100N that the electric current of 3A is reflected on the chucking power, and spends 1 year, the corresponding 60N of 3A electric current, even electric current can not exceed restriction, but the comparison that this moment, speed possibly descend is severe.Thereby possibly make a mistake anti-pinch.
For power windows provides a kind of novel control system, when guaranteeing the power windows pinch resistant functionality reliably, not influencing normal use of vehicle window is the problem that has Technology Need to solve.
The utility model content
The utility model technical problem to be solved is that a kind of electric vehicle window of vehicle is controlled system, when guaranteeing the power windows pinch resistant functionality reliably, is not influencing the normal purpose of using of vehicle window to reach.
For solving the problems of the technologies described above; The technical scheme of the utility model is; A kind of electric vehicle window of vehicle is controlled system; It is characterized in that: described control system is that signal gathering unit passes to signal processing unit with the current signal that collects and compares judgement, signal processing unit control performance element, thus realize pinch resistant functionality through the closed loop feedback of vehicle window drive current.
Described signal gathering unit is current sensor or current acquisition resistance, realizes the real-time monitoring to electric current.
Described signal processing unit is that microcontroller is connected to electric-motor drive unit, and through output PWM waveform, the break-make of operation MOSFET is controlled the output voltage of electric-motor drive unit.
Described performance element is a Car window electric machine.
Described electric-motor drive unit is the H bridge circuit.
A kind of electric vehicle window of vehicle is controlled system, owing to adopt the foregoing circuit structure, this control system has the following advantages: 1, when guaranteeing the power windows pinch resistant functionality reliably, do not influence vehicle window and normally use; 2, through the combination of electric current and speed, adopt adaptive algorithm, the threshold value of real-time update electric current and speed avoids taking place the mistake anti-pinch; 3, can control the electric current that flows through motor, highly versatile arbitrarily.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation;
Fig. 1 is the theory diagram of a kind of electric vehicle window of vehicle control of the utility model system;
Fig. 2 is the fundamental diagram of a kind of electric vehicle window of vehicle control of the utility model system;
In Fig. 1-2,1, signal processing unit; 2, signal gathering unit; 3, performance element; 4, microcontroller; 5, electric-motor drive unit.
The specific embodiment
As shown in Figure 1, the utility model is that signal gathering unit 2 passes to signal processing unit 1 with the current signal that collects and compares judgement, signal processing unit 1 control performance element 3, thus realize pinch resistant functionality through the closed loop feedback of vehicle window drive current.
As shown in Figure 2, the utility model comprises signal gathering unit 2, the signal processing unit 1 that is connected with signal gathering unit 2, and performance element 3.Wherein signal gathering unit 2 is selected current sensor or current acquisition resistance for use, and signal processing unit 1 is made up of with the electric-motor drive unit 5 that is connected with microcontroller 4 microcontroller 4, and performance element 3 is a Car window electric machine; Electric-motor drive unit 5 is the H bridge circuit.The utility model can be controlled the electric current that flows through motor arbitrarily.Like this, can be along with the variation of systematic parameter, suitable adjustment current value guarantees to have enough electric currents to promote motor, and the mistake anti-pinch does not take place.And, can make the voltage power supply of motor with maximum in non-anti-pinch zone, make system's reflection rapidly.Select the circuit of current closed-loop for use; Can use current sensor or current acquisition resistance to gather current signal, use the comparing unit output PWM waveform of microcontroller 4, the break-make of operation MOSFET; Control the magnitude of voltage at motor two ends, and then reach the purpose of control motor current.Also can be in the motor allowed band, the electric current of any condition motor of realization.
The utility model does not use traditional " constant current control ", and adopts " current closed-loop FEEDBACK CONTROL ", just can control the electric current that flows through motor arbitrarily, and universal performance is good.Through the combination of electric current and speed, adopt adaptive algorithm, the threshold value of real-time update electric current and speed solves the situation of anti-pinch by mistake.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as the various improvement of having adopted the utility model technical scheme to carry out; Or directly apply to other occasion without improvement, all within the protection domain of the utility model.
