[0034] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0035] like Figure 1 and Figure 3 As shown in the figure, an embodiment of the present invention provides a parking control method, the control method comprising:

[0036] Step S2: When the vehicle is parked on all four wheels, the first brake is controlled to brake one of the front axle wheels 21 or the rear axle wheels 11. That is, when the vehicle is parked, a parking signal is sent to the first brake, and the first brake generates braking force, thereby performing a parking brake operation on one of the rear axle wheels 11 and the front axle wheels 21.

[0037] Step S3: Control the second brake to brake either the front axle wheel 21 or the other rear axle wheel 11. That is, the control module 400 sends a parking signal to the second brake, which generates braking force, thereby parking the other of the rear axle wheel 11 and the front axle wheel 21. This configuration allows for simultaneous parking of both the front axle wheel 21 and the rear axle wheel 11, improving vehicle parking stability and preventing the vehicle from rolling backwards.

[0038] According to one embodiment of the invention, the parking control method further includes:

[0039] Step S1: Determine whether to put the vehicle into four-wheel parking mode based on the vehicle status information. This method uses the vehicle's status information to determine whether four-wheel parking is necessary, allowing the vehicle to enter parking mode more quickly and accurately.

[0040] Specifically, in step S2, before controlling the first brake to brake one of the front axle wheels 21 or the rear axle wheels 11 when parking the vehicle on all four wheels, there is a step S1. That is, the vehicle status information is used to determine whether the vehicle needs to be parked, and if the vehicle needs to be parked, then step S2 is entered.

[0041] like Figure 1 As shown in the figure, an embodiment of the present invention illustrates a vehicle to better illustrate the parking control method of the present invention. The vehicle includes a front axle wheel 21, a rear axle wheel 11, a first brake member, and a second brake member. The first brake member is used to brake one of the front axle wheel 21 and the rear axle wheel 22, and the second brake member is used to brake the other of the front axle wheel 21 and the rear axle wheel 22.

[0042] The first braking component can be a parking brake 13, and the second braking component includes at least one of a service brake 23 and a drive motor 22. That is, when the vehicle is parked, the first braking component is activated, and the parking brake 13 performs a parking operation on one of the rear axle wheels 11 and the front axle wheels 21.

[0043] Or, the second braking element is activated, and the service brake 23 performs a parking operation on the other of the rear axle wheel 11 and the front axle wheel 21. Alternatively, the drive motor 22 performs a parking operation on the other of the rear axle wheel 11 and the front axle wheel 21. That is, the second braking element can choose to use the service brake 23 for braking, or it can choose to use the drive motor 22 for braking.

[0044] Therefore, when the vehicle is at risk of rolling backwards, the first and second brakes are activated simultaneously, which can improve the stability of the vehicle when parked. The second brake can be used to brake using the service brake 23 or the drive motor 22, so that the vehicle can choose the braking method according to different conditions, thereby improving the success rate of vehicle braking.

[0045] Furthermore, combined Figure 1 and Figure 2 As shown, the second braking element includes a service brake 23 and a drive motor 22. Furthermore, another step in controlling the second braking element to brake the front axle wheel 21 and the rear axle wheel 11 includes:

[0046] Step S21: Control the service brake 23 and drive motor 22 to alternately brake one of the front axle wheels 21 and the rear axle wheels 11. That is, the second braking component includes the service brake 23 and the drive motor 22. Thus, the second braking component can utilize either the service brake 23 or the drive motor 22 for braking. This avoids reducing the lifespan of the drive motor 22 or service brake 23 due to prolonged use of either, and also avoids the risk of brake failure during prolonged braking. The alternating braking between the service brake 23 and the drive motor 22 ensures the safe operation of the parking system 100.

[0047] Specifically, the drive motor 22 can apply a reverse driving force to the wheels to achieve braking.

[0048] According to an optional embodiment of the invention, the service brake 23 includes an electro-hydraulic braking system 40 for driving the brake to operate, and controlling the service brake 23 to alternately brake the front axle wheel 21 and the other of the rear axle wheel 11 with the drive motor 22 includes:

[0049] Step S2111: Obtain the temperature of the electro-hydraulic braking system 40 and the temperature of the drive motor 22. Based on the temperatures of the electro-hydraulic braking system 40 and the drive motor 22, determine whether to switch the current braking component that is braking the other wheel on the front axle 21 or the rear axle 11. In other words, by knowing the temperatures of the electro-hydraulic braking system 40 and the drive motor 22, it is determined whether to switch the current braking component. This can effectively avoid the temperature rise of the electro-hydraulic braking system 40 due to prolonged operation, which would affect the service life of the electro-hydraulic braking system 40, thereby ensuring the safe operation of the parking system 100.

[0050] Step S2112: When the temperature of the electro-hydraulic braking system 40 exceeds the first safe temperature and the temperature of the drive motor 22 is less than or equal to the second safe temperature, the other braking component currently braking the front axle wheel 21 or the rear axle wheel 11 is switched from the electro-hydraulic braking system 40 to the drive motor 22. In other words, when the temperature of the electro-hydraulic braking system 40 exceeds the first safe temperature, the electro-hydraulic braking system 40 has been running for a long time, and its operating temperature has increased. If the electro-hydraulic braking system 40 continues to be used for braking, braking failure is likely to occur. Therefore, the current braking component is switched from the electro-hydraulic braking system 40 to the drive motor 22. Furthermore, when the current braking component is switched from the electro-hydraulic braking system 40 to the drive motor 22, the electro-hydraulic braking system 40 stops working to reduce its temperature.

[0051] Step S2113: When the temperature of the drive motor 22 exceeds the second safe temperature and the temperature of the electro-hydraulic braking system 40 is less than or equal to the first safe temperature, the other braking component currently braking the front axle wheel 21 or the rear axle wheel 11 is switched from the drive motor 22 to the electro-hydraulic braking system 40. In other words, when the temperature of the drive motor 22 exceeds the second safe temperature, the drive motor 22 has been running for a long time, and its operating temperature has increased. If the drive motor 22 is continued to be used for braking, braking failure is likely to occur. Therefore, the current braking component is switched from the drive motor 22 to the electro-hydraulic braking system 40. Furthermore, when the current braking component is switched from the drive motor 22 to the electro-hydraulic braking system 40, the drive motor 22 stops working to reduce its temperature.

[0052] The first safe temperature can be the maximum safe operating temperature of the electro-hydraulic braking system 40, and the second safe temperature can be the maximum safe operating temperature of the drive motor 22.

[0053] The electro-hydraulic braking system 40 serves as the initial braking component for braking the other of the front axle wheels 21 and rear axle wheels 11. In other words, when braking the other of the front axle wheels 21 and rear axle wheels 11, the second braking component employs two braking strategies: using the service brake 23 to provide braking force or using the drive motor 22 to provide braking force. Since the electro-hydraulic braking system 40 is more convenient and faster for braking the other of the front axle wheels 21 and rear axle wheels 11, and causes relatively less damage to the drive motor 22, it is preferentially chosen as the initial braking component for braking the other of the front axle wheels 21 and rear axle wheels 11.

[0054] According to another embodiment of the invention, the control method further includes:

[0055] Step S2121: Obtain the temperature of the electro-hydraulic braking system 40 and the temperature of the drive motor 22;

[0056] Step S2122: Determine whether to trigger an alarm based on the temperature of the electro-hydraulic braking system 40 and the temperature of the drive motor 22;

[0057] Step S2123: When the temperature of the electro-hydraulic braking system 40 exceeds the first safe temperature and the temperature of the drive motor 22 exceeds the second safe temperature, an alarm is triggered. Specifically, when the temperature of the electro-hydraulic braking system 40 exceeds the first safe temperature and the temperature of the drive motor 22 exceeds the second safe temperature, both the electro-hydraulic braking system 40 and the drive motor 22 stop working. The alarm is triggered by the alarm device 70 sending a prompt message to the user to remind them that the current road conditions have exceeded the vehicle's braking range, thus ensuring safety.

[0058] Furthermore, the electro-hydraulic braking system 40 includes a brake motor for driving the brake, and the temperature of the electro-hydraulic braking system 40 includes at least one of the temperatures of the brake motor and the hydraulic oil. That is, a high temperature of the hydraulic oil may damage the brake motor or the service brake component 23, and a high temperature of the brake motor may damage the brake motor itself. The steps for determining whether the temperature of the electro-hydraulic braking system 40 exceeds a first safe temperature include:

[0059] Step S213: Determine whether the temperature of the brake motor is greater than a first threshold, or whether the temperature of the hydraulic oil is greater than a second threshold. If the temperature of the brake motor is greater than the first threshold and / or the temperature of the hydraulic oil is greater than the second threshold, determine whether the temperature of the electro-hydraulic braking system 40 exceeds a first safe temperature. Thus, when the temperature of the brake motor is greater than the first threshold or the temperature of the hydraulic oil is greater than the second threshold, it is determined that the temperature of the electro-hydraulic braking system 40 exceeds the first safe temperature. Alternatively, if the temperature of the brake motor is greater than the first threshold and the temperature of the hydraulic oil is greater than the second threshold, then it is determined that the temperature of the electro-hydraulic braking system 40 exceeds the first safe temperature.

[0060] The temperatures of the first threshold and the second threshold can be the same or different. For example, the first threshold can be the overheating temperature of the brake motor, and the second threshold can be the temperature at which the hydraulic oil damages the brake motor or the service brake component 23.

[0061] According to another optional embodiment of the invention, the step of controlling the service brake 23 and the drive motor 22 to alternately brake one of the front axle wheels 21 or the rear axle wheels 11 further includes:

[0062] Step S231: The service brake 23 and the drive motor 22 alternately brake one of the front axle wheels 21 or the rear axle wheels 11 according to a cycle. That is, the service brake 23 and the drive motor 22 can directly alternate according to a cycle. For example, the optimal operating time of the service brake 23 and the optimal operating time of the drive motor 22 can be determined experimentally. Thus, after the service brake 23 has been running for a preset period of time, the current brake is switched to the drive motor 22, and after the drive motor 22 has been running for a preset period of time, the current brake is switched back to the service brake 23. In this way, the safe operation of the parking system 100 is achieved. That is, the switching condition between the service brake 23 and the drive motor 22 is the operating time of the service brake 23 and / or the operating time of the drive motor 22.

[0063] The optimal working time of the service brake component 23 and the optimal working time of the drive motor 22 can be different or the same.

[0064] According to one embodiment of the invention, the vehicle status information includes the wheel speed information of the vehicle. The steps of obtaining the vehicle status information and determining whether to put the vehicle into four-wheel parking based on the vehicle status information include:

[0065] Step S11: When at least one of the wheel speeds is not 0, and the first brake is applied to either the front axle wheel 21 or the rear axle wheel 11, four-wheel parking is determined. That is, when the first brake is applied to either the front axle wheel 21 or the rear axle wheel 11, if at least one of the wheel speeds is not 0, the parking system 100 needs to be controlled to enter four-wheel parking mode, i.e., both the first and second brakes are activated.

[0066] The first braking component can be a parking brake component 13.

[0067] According to one embodiment of the invention, the control method of the parking system 100 further includes:

[0068] Step S41: Determine whether to issue an alarm based on the vehicle status information, which includes the vehicle's wheel speed information.

[0069] Step S42: When at least one of the wheel speeds is not zero, and the first and second brakes apply four-wheel parking to the vehicle, an alarm is triggered. In other words, when the vehicle is at risk of rolling backwards, an alarm can be triggered to alert the driver to safety.

[0070] Therefore, the alarm modes for vehicle alarms also include the following:

[0071] Alarm 1: When the first brake is engaged in parking operation, if the speed of either the rear axle wheel 11 or the front axle wheel 21 is not 0, it is determined that there is a risk of the vehicle rolling away, and an alarm signal will be sent to the alarm device 70, which will then sound an alarm.

[0072] Alarm 2: When the first and second brakes are simultaneously engaged in parking operation, if the vehicle wheel speed is still not 0, it is determined that there is a risk of the vehicle rolling away, and an alarm signal will be sent to alarm 70, which will then sound an alarm.

[0073] Alarm 3: Both the drive motor 22 and the service brake 23 report that their temperatures have reached the critical temperature for permissible operation. If parking is not performed, it is determined that the vehicle is at risk of rolling away, and an alarm signal is sent to alarm 70. Alarm 70 then sounds an alarm, and the corresponding strategy stops executing. At this point, environmental factors or a vehicle malfunction should be considered.

[0074] The first brake element is used to brake the rear axle wheel 11, and the second brake element is used to brake the front axle wheel 21. Specifically, the parking brake 13 is an EPB (electronic parking brake system). The long-term operation of the service brake 23 will affect the service life of the service brake 23. Therefore, the braking force of the parking brake 13 is increased to achieve parking.

[0075] Reference Figure 1 As shown, the vehicle in this embodiment of the invention has a parking system 100 to implement the parking control method described above.

[0076] like Figure 1 As shown, the parking system 100 also includes a motor controller 50, which is electrically connected to the drive motor 22 and to the control module 400. In other words, the motor controller 50 can control the operation of the drive motor 22.

[0077] The parking system 100 further includes a first temperature sensor and a second temperature sensor. The first temperature sensor is located in the electro-hydraulic braking system 40, and the second temperature sensor is located in the drive motor 22. Both the first and second temperature sensors are electrically connected to the control module 400. Thus, the first temperature sensor can detect the temperature of the electro-hydraulic braking system 40 and send the relevant temperature information to the control module 400. The control module 400 performs logical operations to compare the temperature information with a first safe temperature of the electro-hydraulic braking system 400, thereby controlling the start and stop of the electro-hydraulic braking system 400. Similarly, the second temperature sensor can detect the temperature of the drive motor 22 and send the relevant temperature information to the control module 400. The control module 400 performs logical operations to compare the temperature information with a second safe temperature of the drive motor 22, thereby controlling the start and stop of the drive motor 22.

[0078] Reference Figure 1 As shown, the parking system 100 also includes wheel speed sensors 60, which are installed on the front axle wheels 21 and the rear axle wheels 11. The wheel speed sensors 60 are electrically connected to the control module 400 to provide the control module 400 with wheel speed information for detecting the front axle wheels 21 and the rear axle wheels 11. Thus, the wheel speed sensors 60 are used to determine whether the vehicle is at risk of rolling backwards. Specifically, there are two front axle wheels 21 and two rear axle wheels 11; wheel speed sensors 60 are installed on both front axle wheels 21 and both rear axle wheels 11, thereby effectively improving the accuracy of vehicle rollback detection.

[0079] Among them, the first temperature sensor, the second temperature sensor, and the wheel speed sensor 60 are all types of acquisition modules 200.

[0080] Reference Figure 1 As shown, the parking system 100 also includes an alarm 70, which is electrically connected to the control module 400. The alarm 70 can issue an alarm message when the vehicle rolls down a slope. The alarm message includes instrument text display, horn blast, and sending a message to the vehicle's APP, which can effectively remind the driver, pedestrians, or other vehicles to avoid collisions.

[0081] Therefore, the specific control method of the parking system 100 is as follows:

[0082] When the parking system 100 is activated, the control module 400 controls the parking brake 13 to provide braking force to the rear axle wheel 11, and when the control module 400 receives that the wheel speed of the rear axle wheel 11 and / or the front axle wheel 21 is not 0, the control module 400 controls the second brake to provide braking force to the front axle wheel 21. In other words, when the vehicle is parked, a parking signal is sent to the parking brake 13 of the rear axle wheels 11. The parking brake 13 then performs a parking operation on the rear axle wheels 11. After the parking operation is completed, the control module 400 continuously receives wheel speed signals from the wheel speed sensor 60 to determine if there is a risk of the vehicle rolling away. If the wheel speeds of both the front axle wheels 21 and the rear axle wheels 11 are consistently 0, the control module 400 determines that there is no risk of the vehicle rolling away, and the vehicle completes parking. When the received wheel speeds of the front axle wheels 21 and the rear axle wheels 11 are not 0, it is determined that there is a risk of the vehicle rolling away. At this time, the control module 400 will prioritize sending a parking signal to the second brake. When the second brake receives the parking signal, it will cause the front axle wheels 21 to generate braking force, achieving simultaneous parking of the front axle wheels 21. After the second brake completes braking of the front axle wheels 21, the control module 400 receives wheel speed signals. If the wheel speed signals are consistently 0, it is determined that there is no risk of the vehicle rolling away, and the second brake generates continuous braking force to maintain the vehicle's parking position.

[0083] Furthermore, when the parking brake 13 provides braking force to the rear axle wheels 11 and the second brake provides braking force to the front axle wheels 21, if the wheel speeds of the rear axle wheels 11 and the front axle wheels 21 are not zero, the control module 400 increases the braking force of the parking brake 13. In other words, when both the parking brake 13 and the second brake are engaged, if the speeds of the rear axle wheels 11 and the front axle wheels 21 are not zero, meaning the vehicle still has a risk of rolling backwards, the control module 400 can increase the braking force of the parking brake 13. This improves the braking effect of the rear axle wheels 11, thereby reducing the risk of the vehicle rolling backwards.

[0084] When the vehicle is parked, the parking brake 13 is activated first. To meet the goals of energy conservation and emission reduction, the braking force applied by the parking brake 13 to the rear axle wheels 11 is relatively small at this time. When the parking brake 13 and the second brake are activated simultaneously, but the vehicle is still at risk of rolling backward, braking can be achieved by increasing the braking force of the parking brake 13.

[0085] Furthermore, when the temperature of the electro-hydraulic braking system 40 exceeds the first safe temperature, the control module 400 controls the drive motor 22 to reverse to generate a reverse driving force on the wheels, and the control module 400 controls the electro-hydraulic braking system 40 to stop working. Specifically, when the electro-hydraulic braking system 40 controls the parking brake component 13 and the second brake component to generate braking force, the continuous pressure generated by the electro-hydraulic braking system 40 causes the internal brake motor temperature to continuously rise. When the temperature reaches its own predetermined first safe temperature, the control module 400 receives a signal and sends a parking signal to the motor controller 50. When the motor controller 50 receives the parking signal, it sends a command to the drive motor 22 to generate a reverse driving force. The drive motor 22 executes the command, applying a reverse driving force to the front axle wheels 21, causing the front axle wheels 21 to generate corresponding resistance, thus parking the vehicle. Simultaneously, it sends a cancel parking signal to the electro-hydraulic braking system 40, and the electro-hydraulic braking system 40 cancels the pressure on the front axle wheels 21. After the drive motor 22 generates reverse braking force, the control module 400 will continuously receive wheel speed signals. When the received wheel speed signal is continuously 0, it is determined that there is no risk of the vehicle rolling away, and the vehicle is parked.

[0086] Furthermore, when the temperature of the drive motor 22 exceeds the second safe temperature, the control module 400 controls the parking brake 13 to provide braking force to the rear axle wheels 11 and the second brake to provide braking force to the front axle wheels 21, and the control module 400 controls the drive motor 22 to stop working. In other words, when parking is achieved by reversing the drive motor 22, the drive motor 22 generates a large amount of heat. The motor controller 50 continuously monitors the temperature of the drive motor 22. When the temperature of the drive motor 22 reaches the second safe temperature, it sends a temperature signal to the control module 400. After receiving the temperature signal, the control module 400 resends a parking signal to the electro-hydraulic braking system 40. When the internal temperature monitored by the electro-hydraulic braking system 40 is within a safe range, i.e., the temperature of the electro-hydraulic braking system is less than or equal to the first safe temperature, the electro-hydraulic braking system 40 performs a parking operation, providing braking force to the front axle wheels 21 and the rear axle wheels 11. The motor controller 50 cancels the parking operation, and the drive motor 22 stops working.

[0087] Furthermore, when the temperature of the electro-hydraulic braking system 40 is greater than or equal to the first safe temperature, and the temperature of the drive motor 22 is greater than or equal to the second safe temperature, the control module 400 controls the electro-hydraulic braking system 40 to stop working, and also controls the drive motor 22 to stop working. Thus, when both the electro-hydraulic braking system 40 and the drive motor 22 overheat, the second braking component and the drive motor 22 will not function properly. In this case, it is necessary to control the electro-hydraulic braking system 40 to stop working, and also control the drive motor 22 to stop working, to ensure the service life of the braking system. Then, an alarm is triggered, and a notification message is sent to the user.
