Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a system, method and storage medium for driving a hidden handle to pop open when frozen. Background Art

[0002] With the rapid development of new energy vehicles, especially the rise of pure electric vehicles, hidden door handles are widely used in cars. They seem to be becoming the standard configuration of electric vehicles. Hidden door handles can reduce air resistance and make the overall appearance of the vehicle more integrated. At the same time, the door handles pop out and retract, which greatly enhances the sense of ceremony, technology and intelligence of the vehicle.

[0003] However, in winter, hidden handles are easily frozen and cannot be opened normally. The existing solution for frozen hidden handles is to use the vehicle battery to power the door handle motor when the vehicle is unlocked to unfold the handle. However, the battery voltage of the whole vehicle is usually 12V-13V, while the working voltage of the door lock motor can reach 16V, which cannot use the maximum capacity of the door handle motor. After the battery ages, the voltage will be lower, reducing the actual unfolding capacity of the handle. At the same time, when the door handle is frozen by severe rain and snow in winter, continuous driving will cause the motor to overheat and protect, and it is necessary to wait for the motor to cool down before continuing to operate, affecting the customer experience. Summary of the invention

[0004] In view of the above problems, the present application provides a system, method and storage medium for driving a hidden handle to pop open when it is frozen, so as to solve the problem that when the hidden handle of the existing vehicle is frozen, the door handle motor is driven to unfold by the battery but the maximum capacity of the door handle motor cannot be used.

[0005] To achieve the above object, the inventor provides a system for driving a hidden handle to pop open when frozen, comprising:

[0006] A handle motor, the handle motor being used to unfold a hidden handle of the vehicle;

[0007] A battery connected to the handle motor;

[0008] A high-voltage control module, wherein the high-voltage control module is connected to the handle motor;

[0009] A controller is connected to a battery and a high-voltage control module. The controller is used to control the battery to power the handle motor after the vehicle is unlocked, thereby driving the handle motor to open the hidden handle. When it is detected that the hidden handle fails to unfold, the controller enters the ice-breaking mode, outputs a preset voltage through the high-voltage control module to power the handle motor, and drives the handle motor to unfold the hidden handle.

[0010] In some embodiments, the controller is used to detect whether the hidden handle is deployed via a CAN signal on a hard line.

[0011] In some embodiments, the high voltage control module includes a power battery and a DCDC module;

[0012] The power battery is connected to the handle motor via a DCDC module;

[0013] The control end of the DCDC module is connected to the controller.

[0014] In some embodiments, the high voltage control module is also connected to a battery;

[0015] The controller is also used to supply power to the battery through the high-voltage control module when entering the ice-breaking mode.

[0016] In some embodiments, the controller is a vehicle controller.

[0017] Another technical solution is provided, a method for driving a hidden handle to pop up when frozen, which is applied to the above-mentioned system for driving a hidden handle to pop up when frozen, and the method comprises the following steps:

[0018] When the vehicle is unlocked, the control battery supplies power to the handle motor, which drives the handle motor to open the hidden handle;

[0019] Detect whether the hidden handle is unfolded;

[0020] When it is detected that the hidden handle fails to unfold, the system enters the ice-breaking mode, and the high-voltage control module outputs a preset voltage to power the handle motor, driving the handle motor to unfold the hidden handle.

[0021] In some embodiments, the step of detecting whether the hidden handle is unfolded specifically includes the following steps:

[0022] The CAN signal on the hard line detects whether the hidden handle is unfolded.

[0023] In some embodiments, the following steps are also included:

[0024] When entering the ice-breaking mode, the battery is powered by the high-voltage control module.

[0025] In some embodiments, the step of outputting a preset voltage through the high voltage control module to power the handle motor specifically includes the following steps:

[0026] The preset voltage is sent to the DCDC module, and the high voltage output by the power battery is converted into the preset voltage through the DCDC module to power the handle motor.

[0027] Another technical solution is provided, a storage medium storing a computer program, wherein the computer program, when executed by a processor, executes the steps of the method for driving a hidden handle to pop open when frozen.

[0028] Different from the prior art, the above technical solution uses a battery to power the vehicle after it is unlocked, and the controller drives the handle motor to try to open it for the first time, and then detects whether the hidden handle is successfully deployed. When the hidden handle fails to be deployed, the controller enters the ice-breaking mode, and the high-voltage control module outputs a preset voltage to the handle motor to power the handle motor and drive the handle motor to deploy the hidden handle. When entering the ice-breaking mode, the high-voltage control module outputs a set voltage to power the handle motor, so that the handle motor can achieve maximum capacity to deploy the hidden handle, which can effectively reduce the probability of the handle failing to pop open.

[0053] See also Figure 1 This embodiment provides a system for driving a hidden handle to pop open when frozen, comprising:

[0054] A handle motor 110, wherein the handle motor 110 is used to unfold a hidden handle of the vehicle;

[0055] A battery 120, wherein the battery 120 is connected to the handle motor 110;

[0056] A high voltage control module 130 , wherein the high voltage control module 130 is connected to the handle motor 110 ;

[0057] The controller 140 is connected to the battery 120 and the high-voltage control module 130. The controller 140 is used to control the battery 120 to power the handle motor 110 after the vehicle is unlocked, so as to drive the handle motor 110 to open the hidden handle. When it is detected that the hidden handle fails to be unfolded, the controller 140 enters the ice-breaking mode, and outputs a preset voltage through the high-voltage control module 130 to power the handle motor 110, so as to drive the handle motor 110 to unfold the hidden handle.

[0058] When the vehicle is unlocked, the battery 120 is used for power supply, and the controller 140 drives the handle motor 110 to try to open it for the first time, and then detects whether the hidden handle is successfully deployed. When the hidden handle fails to be deployed, the controller 140 enters the ice-breaking mode, and the high-voltage control module 130 outputs a preset voltage to the handle motor 110 to power the handle motor 110 and drive the handle motor 110 to deploy the hidden handle. When entering the ice-breaking mode, the high-voltage control module 130 outputs a set voltage to power the handle motor 110, so that the handle motor 110 can achieve maximum capacity to deploy the hidden handle, which can effectively reduce the probability of the handle failing to pop open.

[0059] In some embodiments, the controller 140 is used to detect whether the hidden handle is unfolded through a CAN signal on a hard line. The controller 140 detects whether the hidden handle is unfolded through a hard line. In other embodiments, an angle sensor may be provided on the rotating shaft of the hidden handle to detect the unfolding angle of the hidden handle, and whether the hidden handle is opened may be determined based on the unfolding angle of the hidden handle.

[0060] See also Figure 2 , in some embodiments, the high voltage control module 130 includes a power battery and a DCDC module;

[0061] The power battery is connected to the handle motor 110 via a DCDC module;

[0062] The control end of the DCDC module is connected to the controller 140 .

[0063] The high-voltage control module 130 is composed of a power battery and a DCDC module. When the high-voltage control module 130 is required to output a preset voltage, the controller 140 sends the set voltage value to the DCDC module, and the high voltage output by the power battery is converted into a low voltage through the DCDC module. The converted low voltage value is the preset voltage value sent by the controller 140, so that the high-voltage control module 130 outputs the preset voltage. In other embodiments, the high-voltage control module 130 can also be composed of a generator, a rectifier module and a DCDC module of the vehicle. After the generator generates electricity, it is rectified by the rectifier module and converted into a preset voltage by the DCDC module to power the handle motor 110.

[0064] See also Figure 3 , in some embodiments, the high voltage control module 130 is also connected to the battery 120;

[0065] The controller 140 is also used to supply power to the battery 120 through the high-voltage control module 130 when entering the ice-breaking mode.

[0066] When the controller 140 enters the ice-breaking mode, the high-voltage control module 130 supplies power to the battery 120 to ensure that the battery 120 has sufficient power.

[0067] In some embodiments, the controller 140 is a vehicle controller. The controller 140 may be a vehicle controller, and the unfolding action of the hidden handle is completed by the vehicle controller. In other embodiments, the controller 140 may also be a vehicle body controller or a combination of a vehicle body controller and a vehicle controller.

[0068] In some embodiments, Figure 3 As shown, a system for driving a hidden handle to pop open when it is frozen has the following specific working principle: when the vehicle is unlocked, the vehicle battery 120 is used for power supply, and the controller 140 drives the handle motor 110 to try to pop open for the first time; when the handle fails to unfold (the controller 140 detects the unfolded state of the door handle through a hard line), the controller 140 enters the ice-breaking mode, that is, the vehicle is controlled to enter a high-voltage state, and the voltage value for converting high voltage to low voltage is set, and the high-voltage control module 130 converts the high voltage into a low voltage according to the required voltage value (the high-voltage control module 130 includes a high-voltage power battery and a DCDC, that is, it realizes high-voltage power supply and converts the high voltage into a low voltage, and the converted low voltage value is set by the low voltage sent by the controller 140, and the whole vehicle will be powered by the battery 120 and converted into the low voltage output by the DCDC), and the actual capacity of the handle motor 110 is used to control the handle to pop open again with greater force.

[0069] After entering the high-voltage state, the vehicle power supply voltage is converted by the high-voltage control module 130B into a low voltage to supply power to the vehicle, and the power supply voltage is output based on the set voltage value, so the ice-breaking mode does not depend on the service life and performance of the battery 120; because the greater actual capacity of the door handle motor 110 is utilized, the probability of the handle failing to pop open can be effectively reduced. It does not increase the extra cost of the vehicle cost and has good economic performance.

[0070] See also Figure 4 In another embodiment, a method for driving a hidden handle to pop up when frozen is applied to the above-mentioned system for driving a hidden handle to pop up when frozen, and the method comprises the following steps:

[0071] Step S410: When the vehicle is unlocked, the battery is controlled to supply power to the handle motor, and the handle motor is driven to open the hidden handle;

[0072] Step S420: Detect whether the hidden handle is unfolded;

[0073] When it is detected that the hidden handle fails to be unfolded, step S430 is executed: entering the ice-breaking mode, outputting a preset voltage through the high-voltage control module to power the handle motor, and driving the handle motor to unfold the hidden handle.

[0074] When the vehicle is unlocked, the battery is used to power the handle motor to try to open it for the first time, and then detect whether the hidden handle is successfully deployed. When the hidden handle fails to deploy, the ice-breaking mode is entered, and the high-voltage control module outputs a preset voltage to the handle motor to power the handle motor and drive the handle motor to deploy the hidden handle. When entering the ice-breaking mode, the high-voltage control module outputs a set voltage to power the handle motor, so that the handle motor can achieve maximum capacity to deploy the hidden handle, which can effectively reduce the probability of the handle failing to pop open.

[0075] In some embodiments, the step of detecting whether the hidden handle is unfolded specifically includes the following steps:

[0076] The CAN signal on the hard line detects whether the hidden handle is unfolded.

[0077] Whether the hidden handle is unfolded is detected by the CAN signal on the hard line. In other embodiments, an angle sensor may be provided on the rotating shaft of the hidden handle to detect the unfolding angle of the hidden handle, and whether the hidden handle is opened is determined according to the unfolding angle of the hidden handle.

[0078] In some embodiments, the following steps are also included:

[0079] When entering the ice-breaking mode, the battery is powered by the high-voltage control module.

[0080] In some embodiments, the step of outputting a preset voltage through the high voltage control module to power the handle motor specifically includes the following steps:

[0081] The preset voltage is sent to the DCDC module, and the high voltage output by the power battery is converted into the preset voltage through the DCDC module to power the handle motor.

[0082] By using a power battery and a DCDC module to form a high-voltage control module, when the high-voltage control module is required to output a preset voltage, the set voltage value is sent to the DCDC module, and the high voltage output by the power battery is converted into a low voltage through the DCDC module. The converted low voltage value is the preset voltage value sent by the controller, so that the high-voltage control module outputs the preset voltage. In other embodiments, the high-voltage control module can also be composed of a generator, a rectifier module and a DCDC module of the vehicle. After the generator generates electricity, it is rectified by the rectifier module and converted into a preset voltage by the DCDC module to power the handle motor.

[0083] See also Figure 5 In another embodiment, a storage medium 510 stores a computer program, and when the computer program is executed by a processor 520, the steps of the method for driving a hidden handle to pop open when frozen in the above embodiment are performed:

[0084] When the vehicle is unlocked, the control battery supplies power to the handle motor, which drives the handle motor to open the hidden handle;

[0085] Detect whether the hidden handle is unfolded;

[0086] When it is detected that the hidden handle fails to unfold, the system enters the ice-breaking mode, and the high-voltage control module outputs a preset voltage to power the handle motor, driving the handle motor to unfold the hidden handle.

[0087] When the vehicle is unlocked, the battery is used to power the handle motor to try to open it for the first time, and then detect whether the hidden handle is successfully deployed. When the hidden handle fails to deploy, the ice-breaking mode is entered, and the high-voltage control module outputs a preset voltage to the handle motor to power the handle motor and drive the handle motor to deploy the hidden handle. When entering the ice-breaking mode, the high-voltage control module outputs a set voltage to power the handle motor, so that the handle motor can achieve maximum capacity to deploy the hidden handle, which can effectively reduce the probability of the handle failing to pop open.

[0088] In some embodiments, the processor specifically includes the following steps when executing the detection of whether the hidden handle is unfolded:

[0089] The CAN signal on the hard line detects whether the hidden handle is unfolded.

[0090] Whether the hidden handle is unfolded is detected by the CAN signal on the hard line. In other embodiments, an angle sensor may be provided on the rotating shaft of the hidden handle to detect the unfolding angle of the hidden handle, and whether the hidden handle is opened is determined according to the unfolding angle of the hidden handle.

[0091] In some embodiments, the processor further performs the following steps when executing the computer program:

[0092] When entering the ice-breaking mode, the battery is powered by the high-voltage control module.

[0093] In some embodiments, the processor specifically performs the following steps when outputting a preset voltage through the high-voltage control module to power the handle motor:

[0094] The preset voltage is sent to the DCDC module, and the high voltage output by the power battery is converted into the preset voltage through the DCDC module to power the handle motor.

[0095] By using a power battery and a DCDC module to form a high-voltage control module, when the high-voltage control module is required to output a preset voltage, the set voltage value is sent to the DCDC module, and the high voltage output by the power battery is converted into a low voltage through the DCDC module. The converted low voltage value is the preset voltage value sent by the controller, so that the high-voltage control module outputs the preset voltage. In other embodiments, the high-voltage control module can also be composed of a generator, a rectifier module and a DCDC module of the vehicle. After the generator generates electricity, it is rectified by the rectifier module and converted into a preset voltage by the DCDC module to power the handle motor.
