Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to an electric door control system and a vehicle having the same. Background Technology

[0002] With the development of automotive intelligence, electric side-opening doors (hereinafter referred to as electric doors) are increasingly used in automobiles. Electric doors rely on controllers to control the electric door opening drive action, and use Hall sensors in the electric door driver to achieve speed detection and force control, thereby obtaining a comfortable door opening and closing quality.

[0003] However, in the high-temperature environment of summer, the internal resistance of the actuator is small and the door sealing reaction force is small. In the low-temperature environment of winter, the internal resistance of the actuator is large and the door sealing reaction force is large. In order to prevent the door from failing to close in low temperatures, the conventional solution is to use the driving force required for low-temperature environment to open and close the door when it is close to the closed position.

[0004] Therefore, the output force of the electric door opener is a fixed output force that does not change with temperature. In the summer, when the temperature is high, the sealing reaction force is small and the internal resistance of the driver is small. If the door is closed with the driving force at low temperature, it will result in a large closing force and poor sound quality, which urgently needs to be solved. Utility Model Content

[0029] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0030] The above and / or additional aspects and advantages of this utility model will become apparent and readily understood from the following description of the embodiments taken in conjunction with the accompanying drawings, in which:

[0031] Figure 1 This is a block diagram of an electric door control system according to an embodiment of the present utility model. Detailed Implementation

[0032] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0033] The electric door control system and a vehicle having the same are described below with reference to the accompanying drawings, according to embodiments of the present invention.

[0034] Figure 1 This is a block diagram of an electric door control system provided in an embodiment of the present utility model.

[0035] like Figure 1 As shown, the electric door control system 10 includes: an electric opening driver 100, a temperature acquisition component 200, and a control component 300.

[0036] The electric starter drive 100 includes a first motor; a temperature acquisition component 200 is used to acquire outdoor temperature; a control component 300 is connected to the electric starter drive 100 and the temperature acquisition component 200 respectively, and the control component 300 includes a motor data acquisition unit 301, which is configured to store multiple self-closing lock drive currents. The control component 300 is configured to send calibration parameters obtained from the outdoor temperature and the average value of multiple self-closing lock drive currents to the electric starter drive 100, so that the electric starter drive 100 drives the first motor to close the door based on the calibration parameters.

[0037] Optionally, in some embodiments, the control component 300 includes: a driver motor drive module 302 and a control unit 303, wherein the control unit 303 is connected to the temperature acquisition component 200 and the driver motor drive module 302 respectively, and the control unit 303 is configured to send calibration parameters determined by the outdoor temperature and the average value of multiple self-closing lock driver currents to the driver motor drive module 302; the driver motor drive module 302 is connected to the electric opening driver 100, and the driver motor drive module 302 is configured to send calibration parameters to the electric opening driver 100, so that the electric opening driver drives the first motor to close the door based on the calibration parameters.

[0038] Optionally, in some embodiments, the control unit 303 includes a data acquisition subunit. The data acquisition subunit is connected to an electrically operated driver and is configured to acquire the current rotational speed of the first motor.

[0039] Specifically, the electric door controller (i.e., control component 300) will be calibrated according to the actual vehicle, including the environment: high temperature, low temperature, normal temperature; slope: front and rear slope, left and right slope; various humidity levels, etc., individual working conditions and combined working conditions. After multiple rounds of calibration, various calibration parameters are reasonably adjusted and finally locked. The calibration parameters include the motor voltage and current of the electric opening driver 100, the Hall signal (feedback motor speed), and the current of the self-priming lock driver 400 under various working conditions. These calibration data will be permanently stored in the electric controller.

[0040] After system calibration, when the control component 300 receives a door closing command, it determines whether the door opening conditions are met. If the conditions are met, the control unit 303 first obtains the current outdoor temperature from the temperature acquisition component 200. The motor data acquisition unit 301 pre-stores current data from multiple self-closing lock actuator operations. The control unit 303 retrieves the stored current data from the motor data acquisition unit 301 and calculates the average current value, which is inversely proportional to the door sealing reaction force. The control unit 303 then combines the outdoor temperature and the average current value to retrieve the system calibration parameters and sends these calibration parameters to the driver motor drive module 302. The driver motor drive module 302 then forwards the parameters to the electric opening driver 100. Finally, the electric opening driver 100, based on the received calibration parameters, controls the first motor to output appropriate power (such as current and speed) to complete the door closing action.

[0041] Optionally, in some embodiments, the electric door control system 10 described above further includes a self-closing lock driver 400. The self-closing lock driver 400 includes a second motor, is connected to the control component 300, and is configured to drive the second motor to close the door.

[0042] Optionally, in some embodiments, the control component 300 further includes a self-priming motor drive module 304, which is connected to the control unit 303, the motor data acquisition unit 301, and the self-priming lock driver 400, respectively. The self-priming motor drive module 304 is configured to send a closing command to the self-priming lock driver 400, so that the self-priming lock driver 400 drives the second motor to close the door.

[0043] Specifically, the current data of the self-closing lock actuator 400 in closing the car door under different scenarios is stored in the motor data acquisition unit 301. When the car door begins to close, the first stage is dominated by the electric opening actuator 100: the control unit 303 first obtains the outdoor temperature from the temperature acquisition component 200, then retrieves the historical current data of the electric opening actuator from 301 and calculates the average value, combines the two to retrieve the system calibration parameters, and forwards them to the electric opening actuator 100 through the actuator motor drive module 302. Finally, the first motor drives the car door from the open state to the half-closed position (i.e., the edge of the car door is close to the door frame, but not fully locked). In the second stage: the control unit 303 again retrieves the historical current data of the self-closing lock actuator 400 from 301, retrieves the system calibration parameters in combination with the outdoor temperature, and sends the closing command to the self-closing motor drive module 304. The self-closing motor drive module 304 forwards the closing command to the self-closing lock actuator 400, so that the self-closing lock actuator 400 drives the second motor to close the car door.

[0044] Therefore, the control component connects the electric door opener and the temperature acquisition component, and its motor data acquisition unit stores multiple self-closing lock driver currents. The control component calculates calibration parameters by combining the outdoor temperature with the average value of these currents, and sends them to the electric door opener, which then drives the first electric door to close. This solves the problem of poor sound quality when closing the door in high-temperature environments and optimizes the driver's driving experience.

[0045] Furthermore, in addition to the basic process of determining calibration parameters and driving the motor to close the door by using temperature and historical current data, the control components also include a real-time monitoring and dynamic adjustment mechanism to further ensure the accuracy of the door closing action and the stability of the system, and to conduct closed-loop management of the operating status of the first motor.

[0046] Optionally, in some embodiments, the control unit 303 further includes a detection subunit. The detection subunit is connected to the acquisition subunit and is configured to generate an adjustment command when the current speed of the first motor does not meet the preset calibration requirements, causing the control unit to resend the calibration parameters to the driver motor drive module 302.

[0047] Optionally, in some embodiments, the control component 300 further includes: a counting unit, which is connected to the detection subunit and configured to accumulate the number of times the current rotational speed of the first motor does not meet the preset calibration requirements; and a communication unit, which is connected to the counting unit and configured to send the number of consecutive occurrences to a preset mobile terminal if the number of consecutive occurrences exceeds a preset number.

[0048] Specifically, the detection subunit is connected to the acquisition subunit. When the first motor is working, the detection subunit of the control unit 303 monitors the current speed of the first motor in real time. If the speed does not meet the preset calibration requirements, an adjustment command is generated, prompting the control unit 303 to recalculate and send new calibration parameters to the driver motor drive module 302 to ensure that the motor speed meets the standard. The counting unit is connected to the detection subunit. The counting unit accumulates the number of times the speed does not meet the standard. When the accumulated number exceeds a preset value, the communication unit will send the number (e.g., via wireless signal, Bluetooth, etc.) to a preset mobile terminal (e.g., the driver's mobile phone, vehicle management platform, etc.) for timely warning.

[0049] This avoids incomplete door closing or excessive operation due to abnormal rotation speed. At the same time, by accumulating the number of abnormalities and triggering warnings, potential system faults can be detected in a timely manner, further improving the stability and safety of the entire door control system.

[0050] Optionally, in some embodiments, the electric door control system 10 described above further includes a power supply component 500. The power supply component 500 is connected to the control component 300 and is used to supply power to the control component 300.

[0051] Alternatively, in some embodiments, the power supply component 500 is a battery.

[0052] Specifically, the power supply component 500 is the energy core of the electric door control system, connected to and supplying power to the control component 300. The power supply component 500 can be a battery, which can automatically recharge, ensuring continuous operation of the control component when the main power supply is interrupted. It also features overcharge protection and low battery warning functions. Besides batteries, the power supply component 500 can also take other forms. For example, it can be directly connected to the vehicle's onboard power system, or a supercapacitor can be used. Different power supply methods can be selected according to the needs of the actual usage scenario.

[0053] According to the electric door control system proposed in this utility model, the control component is connected to the electric door opener and the temperature acquisition component. Its motor data acquisition unit stores multiple self-closing lock driver currents. The control component calculates calibration parameters by combining the outdoor temperature with the average value of these currents, and sends them to the electric door opener. The electric door opener then drives the first electric door to close. This solves the problem of poor sound quality when closing the door in high-temperature environments and optimizes the driver's driving experience.

[0054] Furthermore, this utility model embodiment also proposes a vehicle, which includes... Figure 1 The electric door control system shown in the embodiment.
