Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
At present, the doors of many vehicle types in the market are provided with an unlocking motor and a self-priming motor, wherein the self-priming motor is used for assisting in closing the door, and a user only needs to close the door to a certain angle, and then the vehicle can control the self-priming motor to assist the door in the closing direction, so that the user can completely close the door without applying force like a common vehicle type, and further the automatic suction of the door is realized; the unlocking motor drives the door lock mechanism to move from the closed position to the open position, so that the unlocking of the vehicle door is realized.
Under normal conditions, the unlocking motor can meet the unlocking requirement of the vehicle, however, under the environment with lower air temperature, such as in rainy and snowy weather, the vehicle door is easily frozen, at the moment, the unlocking motor usually cannot provide enough ejection force, further ice cannot be broken, and the condition that the vehicle door cannot be pulled open occurs.
The application aims at not changing the basis of door structure, under the unable condition of breaking ice of unblock motor, through control self-priming motor reversal in order to provide the required ejection force of breaking ice to adopt the circulation ice-breaking strategy that opens ice-resets, effectively improve the success rate of breaking ice when avoiding motor long-time reversal work to damage, improve user's use experience.
Referring to fig. 1, there is shown a method of breaking ice for a motor vehicle door of the present application, which may include the steps of:
step S101: and when the unlocking motor does not open the vehicle door within a first preset time, determining that the vehicle door is frozen.
In this embodiment, considering that the door is only partially frozen, the unlocking motor is utilized to open the door, and at this time, the self-priming motor is not required to be started to break ice, so in this embodiment, the unlocking motor is utilized to open the door first, and by setting a first preset time, the unlocking condition of the door is detected in a delayed manner, if the door is still in a closed state after the first preset time, it is indicated that the ejection force provided by the unlocking motor cannot open the door, and further it is determined that the door is frozen.
Preferably, the first preset time may be set to 2 seconds, that is, the unlocking motor fails to unlock the door within 2 seconds, it is determined that the door is frozen, and the unlocking motor is controlled to stop working.
Step S102: and controlling the self-priming motor to rotate reversely in a second preset time to break ice of the vehicle door, and controlling the self-priming motor to rotate forwards and reset after the second preset time.
In the embodiment, the self-priming motor positively rotates to drive the working process of the vehicle door from the open state to the closed state; the reverse rotation of the self-priming motor refers to the working process of driving the vehicle door from a closed state to an open state. The present embodiment is not limited to the direction of rotation of the self-priming motor in the forward or reverse direction, and may be applied to the reverse direction of the self-priming motor in the reverse direction and the reverse direction of the motor in the forward direction. It should be noted that, in the process of breaking ice, the self-priming motor can continuously reverse in the second preset time to provide continuous ejection force, after the second preset time, no matter whether the door breaks ice successfully, the self-priming motor can be controlled to forward rotate to restore to the working state before breaking ice, and then forward rotation reset of the self-priming motor is realized. In this embodiment, the self-priming motor can provide 2000-3000N force during reversing, so that when the unlocking motor cannot unlock the door, the self-priming motor is controlled to reverse, and a sufficiently large ejection force can be provided to break ice on the door. In this embodiment, by setting the second preset time and controlling the forward rotation and the reset of the self-priming motor after the second preset time, damage caused by long-time reverse rotation operation can be avoided, and preparation is made for breaking ice on the vehicle door next time.
In this embodiment, the second preset time may be set to 0.5 seconds, that is, after the self-priming motor rotates reversely for 0.5 seconds, the unlocking motor is controlled to perform the reset operation no matter whether the door breaks ice successfully or not.
In this embodiment, the self-priming motor is controlled to work by adopting an electric control pulse width modulation technology, a voltage signal with a certain frequency loaded on the self-priming motor is modulated by a vehicle body controller 401, and the voltage average value of the voltage signal on the self-priming motor is controlled by controlling the ratio of the effective voltage by switching on and off of a switching circuit, so that the current control on the self-priming motor is finally realized, and the accurate and continuous control on the state of the self-priming motor is realized.
In this embodiment, to ensure the maximum intensity of the output of the ice breaking force during the ice breaking process of the self-priming motor, the vehicle body controller 401 outputs a duty cycle of 100%, so that the self-priming motor can operate at the maximum allowable power within the operation time of 0.5 seconds, and a continuous maximum intensity ejection force is provided to break ice on the vehicle door.
Step S103: judging whether the self-priming motor breaks ice successfully or not.
In this embodiment, for the situation of possible ice breaking failure of the self-priming motor when the self-priming motor breaks ice on the vehicle door for the first time, whether the self-priming motor breaks ice successfully can be judged through the current unlocking condition of the vehicle door, and preconditions are provided for whether the self-priming motor needs to be started again to break ice on the vehicle door.
Step S104: and under the condition that the self-priming motor fails to break ice, controlling the self-priming motor to reversely rotate within a second preset time to break ice on the vehicle door, and controlling the self-priming motor to reversely rotate and reset after the second preset time until the ice breaking is successful or the ice breaking times reach the preset ice breaking times.
The embodiment needs to be explained that the control of the self-priming motor to reverse again is performed on the basis that the self-priming motor is reset, namely, a circulating ice breaking strategy of ice breaking-resetting-ice breaking-resetting is adopted, so that the success rate of ice breaking is effectively improved while damage caused by long-time reverse operation of the motor is avoided.
In this embodiment, as a preferred solution, the preset number of times of breaking ice may be set to ten times, that is, if the self-priming motor fails after attempting to break ice on the vehicle door for the first time, the self-priming motor may be controlled to invert within a second preset time again to break ice on the vehicle door, so that the self-priming motor is repeatedly utilized to invert to break ice on the vehicle door until the breaking of ice is successful or the number of times of breaking ice reaches 10.
In this embodiment, in order to avoid overheating during continuous reverse rotation of the self-priming motor, the service life of the self-priming motor is reduced, and after each forward rotation reset of the self-priming motor, a third preset time may be set under the condition that the self-priming motor tries to break ice for a second preset time, so that each time of breaking ice after the self-priming motor tries to break ice for the second preset time, the self-priming motor can be restarted at intervals of the third preset time until the breaking ice is successful or reaches the preset breaking ice time, where the second preset breaking ice time is preferably 5 times, and the third preset time is preferably 3 seconds.
In one example, the self-priming motor is controlled to rotate reversely with the maximum power to break ice on the vehicle door within 0.5 seconds, and after the self-priming motor continuously works for 0.5 seconds, the self-priming motor is controlled to rotate forwards and reset until the self-priming motor tries to break ice for the 5 th time, at this time, in order to avoid overheat damage of the self-priming motor, the self-priming motor is restarted after 3 seconds, so as to wait for the temperature of the self-priming motor to drop to the normal working temperature, and the self-priming motor can be restarted after each break ice after the self-priming motor tries to break ice for 5 times, until the ice breaking is successful or the number of times of breaking ice reaches 10.
In the embodiment, under the condition that the unlocking motor does not open the vehicle door within the first preset time, the vehicle door is determined to be frozen, and the self-priming motor is controlled to rotate reversely within the second preset time to break ice on the vehicle door, so that the ejection force required by breaking ice can be provided; if the self-priming motor fails to break ice, the self-priming motor can be controlled to reversely rotate in the second preset time to break ice on the vehicle door until the ice breaking is successful or the ice breaking times reach the preset ice breaking times, and the self-priming motor is controlled to reversely rotate and reset after the vehicle door is broken each time, so that the self-priming motor can avoid damage caused by long-time reverse rotation work, and the success rate of breaking ice on the vehicle door can be effectively improved on the premise that the structure of the vehicle door is not changed through the circulating ice breaking of the self-priming motor, and the use experience of a user is improved.
In a possible embodiment, step S103 may include the following specific steps:
step S103-1, judging whether a triggered signal of the half-lock micro switch is received.
It should be noted that, in this embodiment, the electronic vehicle door generally has three states, including full lock, half lock and full open. The three states are detected through a full-lock micro switch and a half-lock micro switch respectively, wherein when the vehicle door is in a full-lock state, the full-lock micro switch is triggered, and a full-lock micro switch triggered signal is sent to the vehicle body controller 401 to indicate that the current vehicle door goes out of the full-lock state; when the vehicle door is in a half-lock state, at the moment, the half-lock micro switch is triggered, and a half-lock micro switch triggered signal is sent to the vehicle body controller 401 to indicate that the vehicle door is in a half-lock state currently; if the body controller 401 does not receive the full-lock micro-switch triggered signal or the half-lock micro-switch triggered signal, it indicates that the vehicle door is fully opened.
Step S103-2, under the condition that the trigger signal of the half-lock micro switch is received, judging that the vehicle door is in a full-lock state, and determining that the self-priming motor breaks ice successfully.
And step S103-3, judging that the vehicle door does not exit from the full-lock state under the condition that the triggered signal of the half-lock micro switch is not received, and determining that the self-priming motor fails to break ice.
In this embodiment, the door is normally frozen in the full-lock state, and therefore, if the door is frozen and the half-lock micro-switch is triggered, it is indicated that the door has been switched from the full-lock state to the half-lock state, and further it can be determined that the self-priming motor has broken ice successfully. And under the condition that the triggered signal of the half-lock micro switch is not received, the fact that the vehicle door does not exit the full-lock state is indicated, and further, the self-priming motor ice breaking failure can be judged, and the next ice breaking attempt is ready to enter.
In a possible embodiment, during controlling the self-priming motor to reverse for breaking ice of the vehicle door within a second preset time, the electric vehicle door breaking method may further include the steps of:
step S104: receiving an ice breaking stop instruction sent by the central control system within the second preset time;
in this embodiment, in order to enable the user to stop the self-priming motor at any time according to the actual requirement, the present embodiment provides an ice breaking interruption function, that is, the user may send an ice breaking stop instruction to the vehicle body controller 401 through the central control system during the period of controlling the self-priming motor to reverse in a second preset time to break ice on the vehicle door, so as to stop the self-priming motor.
Step S105: according to the ice breaking stopping instruction, the self-priming motor is controlled to rotate reversely in a second preset time to break ice on the vehicle door, and after the second preset time, the self-priming motor is controlled to rotate forwards to reset and stop working.
In this embodiment, after receiving the ice breaking stop command, the vehicle body controller 401 controls the self-priming motor to continue to rotate reversely within a second preset time, so as to break ice on the vehicle door, i.e. after completing the current ice breaking-resetting cycle, then controls the self-priming motor to stop working.
In summary, according to the method for breaking ice of the electric vehicle door, under the condition that the unlocking motor does not open the vehicle door within the first preset time, the vehicle door is determined to be frozen, and the self-priming motor is controlled to rotate reversely with the maximum power within the second preset time to break ice of the vehicle door, so that ejection force required by breaking ice can be provided; if the self-priming motor fails to break ice, the self-priming motor can be controlled to reversely rotate in the second preset time to break ice on the vehicle door until the ice breaking is successful or the ice breaking times reach the preset ice breaking times, the self-priming motor is controlled to positively rotate and reset after the vehicle door is broken ice each time, and a self-priming motor cooling strategy is added in the process of circularly breaking ice on the self-priming motor.
