Example
The invention provides a control method of electric tail anti-violence switches , which comprises the following steps as shown in figure 1:
obtaining speed of the power tail , and determining movement trend of the power tail ;
if the electric tail is determined to be in the th state according to the th speed, the electric tail is controlled to complete braking operation according to the motion trend.
That is, the invention judges whether the electric tail is in the th state according to the speed by acquiring the th speed (i.e. the movement speed of the electric tail at this time) and the movement trend (i.e. whether the electric tail is being turned off or turned on ) of the electric tail , and then the driving device of the electric tail completes the braking operation according to the movement trend.
It should be noted that before acquiring the speed of the electric tail and determining the movement trend of the electric tail , it is necessary to determine whether the electric tail is in the electric mode or the manual mode, and the problem to be solved by the present invention is the anti-violence switch in the manual mode, and in addition, the determination of whether the electric tail is in the electric mode or the manual mode can be determined according to the general control device in the vehicle.
It should be noted that the th state represents the force switch state, i.e., the external force is used to press or lift the power tail , and of course, the manual switch is operated at a speed no greater than the predetermined operating speed to represent the second state.
In this embodiment, the component for acquiring the speed of the electric tail is a hall sensor, the hall sensor acquires the 4 speed of the electric tail 0, and then sends the information to a vehicle Body Control Module (BCM), the BCM serves as a logic operation center, the BCM determines the movement trend (the trend of opening 2 or closing 3) of the electric tail 1 according to the 6 th speed, and determines whether the electric tail 5 is in the th state, and then the BCM sends an instruction to the electric tail controller, the electric tail controller controls a driving device (in this embodiment, the driving device is a strut motor) of the electric tail to complete the corresponding braking operation, that is, the trend of closing is set braking operation, the trend of opening is another set braking operation, and the corresponding braking operation is performed according to different movement trends.
, the step of obtaining the th speed of the motorized tail , the step of determining the trend of the motion of the motorized tail comprises:
the hall sensor collects the different hall position values of the power tail per unit time and converts to the th speed of the power tail .
In this embodiment, the th speed of the power tail is represented by obtaining a change in the hall position of the hall sensor.
Further , the trend of motion includes an on trend and an off trend, for example, when the hall position value of the hall sensor is positive, the power tail can be determined to be in an on trend, and when the hall position value of the hall sensor is negative, the power tail can be determined to be in an off trend.
It should be noted that the positive displacement and the negative displacement correspond to the upward movement of the power tail and the downward movement of the power tail , respectively.
It should be noted that the speed of the power tail is not limited to a hall sensor, and the speed of the power tail may be sensed by a speed sensor, for example.
, if it is determined that the electric tail is in the state according to the speed, the step of controlling the electric tail to complete the braking operation according to the movement trend includes:
comparing the th speed with the preset operation speed, judging whether the th speed exceeds the preset operation speed, if so, judging that the electric tail is in the th state.
For example, if the preset operating speed is 0.8m/s, when the speed of the inductive power tail is 2m/s, it indicates that the power tail is under a great pushing or lifting force, and thus it is determined that the power tail is in the th state, i.e., being subjected to the force switch .
, if it is determined that the tail is in the state according to the speed, the step of controlling the tail to complete the braking operation according to the movement trend further includes:
when the power tail is in the opening trend, a deceleration curve is calculated based on the current position of the power tail and the maximum open stop threshold position.
That is, if it is determined that the electric tail is in the ascending process, that is, in the trend of the opening , the current position of the electric tail is combined, for example, taking the electric tail as an example, the position of the handle (the included angle with respect to the horizontal plane is 0 °) is turned upwards by 35 ° when the electric tail is locked, and according to the known maximum opening stop threshold position, that is, the upward maximum turning angle of the handle is 80 ° with respect to the horizontal plane, at this time, deceleration curves are calculated, in this embodiment, the abscissa of the deceleration curve is time, and the ordinate is an angle, that is, the angle required to be turned upwards is just stopped to be 80 ° with respect to the horizontal plane within time.
The drag braking process is then accomplished by applying a back emf to the strut motor according to the deceleration curve to stop the tail motion before the maximum mechanical limit is reached to protect the strut, i.e., the back emf is applied to the strut motor to stop the tail before it is at its maximum, thereby preventing the break from damaging the strut.
Similarly, if it is determined that the power tail is in the descending process, i.e., the trend of closing , the current position of the power tail is combined, e.g., the power tail is turned downward by 35 ° from 80 ° to 45 ° relative to the horizontal plane, and according to the known minimum closing stop threshold position, e.g., the angle of 0 ° relative to the horizontal plane, second deceleration curves are calculated, in this embodiment, the abscissa of the second deceleration curve is time, and the ordinate is angle, i.e., the angle of downward turning needs to be stopped to just 0 ° within times.
And then, the speed reduction braking process is realized by applying reverse electromotive force to the stay bar motor, the tail stops moving before the tail enters the self-attraction process, and the mechanical structure of the self-attraction lock is protected, namely, the electric tail stops before reaching the lowest position by applying reverse electromotive force to the stay bar motor, so that the mechanical structure of the self-attraction lock is prevented from being damaged by the violent switch .
It should be noted that the electric tail controller has two modes of wake-up (activation) and sleep, only performs logic operation in the wake-up mode, and when in the sleep mode, the hall position of the hall sensor changes to be used as a wake-up source, so that the electric tail controller can enter the wake-up mode from the sleep mode, and respond in time.
The embodiment discloses control methods of an electric tail anti-violence switch , which protect the mechanical structure of the electric tail by judging whether the state is the th state of the anti-violence switch and controlling a driving device when the state is the th state, and the method distinguishes two movement trends of opening and closing for control, thereby improving the control efficiency.
