Description

Technical Field

[0001] The present application relates to the field of vehicle braking technology, and in particular to an automatic parking control method, device, electronic device and storage medium. Background Art

[0002] With the development of intelligent driving technology, the level of vehicle automation continues to improve, and automatic parking systems are becoming widely used. When the driver presses the brake pedal while the vehicle is parked, the system automatically maintains the vehicle's current parking position without the driver having to keep the brake pedal depressed. This prevents foot fatigue even during long parking periods. When the driver presses the accelerator pedal again, the system automatically releases the brakes and starts the vehicle. However, traditional automatic parking systems have simple operating logic, poor adaptability in complex scenarios and dynamic conditions, and low flexibility, making them unable to meet driver needs.

[0054] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0055] In this application, the terms "first", "second", etc. are used to distinguish identical or similar items with substantially the same effects and functions. It should be understood that there is no logical or temporal dependency between "first", "second", and "nth", nor is there any limitation on the quantity and execution order.

[0056] In the present application, the term "at least one" means one or more, and the term "plurality" means two or more.

[0057] It should be noted that the information (including but not limited to user device information, user personal information, etc.), data (including but not limited to data used for analysis, storage, and display, etc.), and signals involved in this application are all authorized by the user or fully authorized by all parties, and the collection, use, and processing of relevant data must comply with the relevant laws, regulations, and standards of the relevant countries and regions. For example, the vehicle status parameters involved in this application are all obtained with full authorization.

[0058] Figure 1 This is a schematic diagram of an implementation environment of an automatic parking control method provided by an embodiment of the present application. Figure 1 The implementation environment includes a parameter acquisition device 101 and a vehicle controller 102, and the implementation environment is deployed in a vehicle. The parameter acquisition device 101 and the vehicle controller 102 can be directly or indirectly connected via wired or wireless communication, which is not limited in this application.

[0059] The parameter acquisition device 101 is used to collect vehicle status parameters. These parameters include brake pedal push rod travel, brake pedal pedal change rate, accelerator pedal push rod travel, accelerator pedal change rate, motor speed, actual gear position, and ignition switch position. It should be noted that the parameter acquisition device 101 includes at least multiple sensors for collecting vehicle status parameters, such as acceleration sensors, pressure sensors, and displacement sensors. The parameter acquisition device 101 may also include a data transmission module for transmitting the vehicle status parameters to the vehicle controller 102.

[0060] The vehicle controller 102 is used to obtain vehicle status parameters, determine whether the vehicle's operating state is any of the preset states, and, if the vehicle's operating state is any of the preset states, control the vehicle to implement a braking function. This braking function includes temporary braking and parking braking. It should be noted that the vehicle controller 102 obtains the vehicle's status parameters from the parameter acquisition device 101. This application does not limit the data acquisition and data transmission methods.

[0061] Figure 2 This is a flow chart of an automatic parking control method provided by an embodiment of the present application, which is executed by a vehicle controller. Figure 2 , the method comprises the following steps:

[0062] 201. Obtain vehicle status parameters, including brake pedal push rod stroke, brake pedal stepping change rate, accelerator pedal push rod stroke, accelerator pedal stepping change rate, motor speed, actual gear position, and ignition switch gear position.

[0063] In the embodiments of the present application, state parameters refer to various data reflecting the current operating status of the vehicle. The brake pedal push rod travel indicates the degree to which the brake pedal is depressed, and the brake pedal depression rate of change indicates the change in speed at which the brake pedal is depressed. The accelerator pedal push rod travel indicates the degree to which the accelerator pedal is depressed, and the accelerator pedal depression rate of change indicates the change in speed at which the accelerator pedal is depressed. The motor speed indicates the rotational speed of the vehicle's drive motor. The ignition switch position indicates the state of the vehicle's ignition system. For example, the ignition switch position (ON) indicates that the vehicle's ignition system is active, and the vehicle's electrical system is typically powered on; the ignition switch position (OFF) indicates that the vehicle's ignition system is off, and the vehicle's engine is stopped, and the vehicle's electrical system is typically powered off. The actual gear position indicates the vehicle's current transmission gear state. The actual gear position directly reflects the vehicle's power transmission and driving status. Actual gear positions typically include P (park), N (neutral), R (reverse), and D (drive). Park is used for extended parking, locking the drive shaft and preventing the vehicle from moving. Neutral disengages the vehicle's drivetrain, preventing engine power from reaching the wheels. Reverse is used for reverse driving, while forward is for normal driving.

[0064] By obtaining the vehicle's status parameters, it is easy to determine the vehicle's current operating status, providing accurate data support for subsequent judgment and control.

[0065] 202. Based on the vehicle state parameters, determine whether the vehicle's operating state is any preset state.

[0066] In the embodiments of the present application, the "preset state" refers to a pre-set state condition used to determine whether the vehicle needs to perform a braking operation. This state condition can be a combination or threshold value based on state parameters such as the travel and change rate of the brake and accelerator pedals, motor speed, actual gear position, and ignition switch position. This condition can be determined based on actual needs and experiments and is not limited here.

[0067] By comparing the vehicle's current operating status with the preset status, it is possible to accurately determine whether the vehicle needs to perform braking operations, thereby ensuring driving safety.

[0068] 203. When the vehicle's operating state is any preset state, a temporary braking function of the vehicle is activated, where the temporary braking function is used to achieve service braking of the vehicle.

[0069] In the embodiments of this application, the temporary braking function refers to a braking function that is temporarily activated to slow down or stop the vehicle, with the same effect as service braking. Service braking is the process of slowing down or stopping the wheels through friction between the brake pads and the brake disc or drum, thereby slowing down or stopping the vehicle. Accordingly, the ECU (Electronic Control Unit) sends preset instructions to the service brake solenoid valve, which then generates service braking force to achieve service parking.

[0070] By first activating the vehicle's temporary braking function, the vehicle speed is effectively slowed down and driving safety is ensured.

[0071] 204. When the duration of the temporary braking function of the vehicle exceeds a first preset duration, the parking brake function of the vehicle is activated and the temporary braking function is released.

[0072] In this embodiment of the present application, the first preset duration refers to a pre-set time threshold for determining whether the vehicle needs to switch from temporary braking to parking braking. The parking brake function is a braking function activated for long-term parking. The parking brake locks the vehicle's drive shaft or rear wheels and is typically used to prevent the vehicle from moving when stationary.

[0073] By automatically switching to the parking brake function, the vehicle is ensured to stop stably, while by releasing the temporary braking function, unnecessary energy consumption and wear are avoided.

[0074] An embodiment of the present application provides an automatic parking control method, in which the vehicle's operating state can be determined by obtaining the vehicle's state parameters. Thus, when the vehicle's operating state is any preset state, the vehicle's temporary braking function is activated according to a preset strategy. Furthermore, when the vehicle executes the temporary braking function for a period exceeding a first preset duration, the vehicle's parking brake function is activated. Because the vehicle's state parameters include multiple parameters such as the brake pedal push rod travel, the brake pedal's pedaling rate of change, the accelerator pedal push rod travel, the accelerator pedal's pedaling rate of change, the motor speed, the actual gear position, and the ignition switch gear position, the current vehicle's operating state and corresponding scenarios can be accurately determined, enabling the vehicle to adopt a corresponding braking strategy, thereby better adapting to a variety of complex scenarios and dynamic conditions and providing greater flexibility.

[0075] Figure 3 This is a flow chart of another automatic parking control method provided by an embodiment of the present application, which is executed by the vehicle controller. Figure 3 , the method comprises the following steps:

[0076] 301. Obtain vehicle status parameters, including brake pedal push rod stroke, brake pedal stepping change rate, accelerator pedal push rod stroke, accelerator pedal stepping change rate, motor speed, actual gear position, and ignition switch gear position.

[0077] In the embodiments of the present application, vehicle status parameters are collected and acquired in real time. Status parameters refer to various data reflecting the current operating status of the vehicle. For ease of description, the brake pedal may also be referred to as the foot brake pedal, service brake pedal, or foot brake pedal, and the accelerator pedal may also be referred to as the accelerator pedal or accelerator pedal.

[0078] The brake pedal push rod stroke indicates the degree to which the brake pedal is depressed, and the brake pedal depression rate of change indicates the change in speed at which the brake pedal is depressed. The accelerator pedal push rod stroke indicates the degree to which the accelerator pedal is depressed, and the accelerator pedal depression rate of change indicates the change in speed at which the accelerator pedal is depressed. The motor speed indicates the rotational speed of the vehicle's drive motor. The ignition switch position indicates the state of the vehicle's ignition system. For example, the ignition switch position (ON) indicates that the vehicle's ignition system is activated, and the vehicle's electrical system is typically powered on. The ignition switch position (OFF) indicates that the vehicle's ignition system is turned off, and the vehicle's engine is stopped, and the vehicle's electrical system is typically powered off.

[0079] Among them, the actual gear position indicates the current transmission gear state of the vehicle. The actual gear position directly reflects the power transmission and driving status of the vehicle. The actual gear position usually includes P gear (parking gear), N gear (neutral gear), R gear (reverse gear) and D gear (forward gear), and may also include S gear (sports gear) and L gear (low gear), etc., which are not restricted here. Among them, the parking gear is used for long-term parking, locking the drive shaft to prevent the vehicle from moving. Neutral gear is used to disconnect the vehicle's transmission system, and the engine power will not be transmitted to the wheels. Reverse gear is used for reverse driving, and forward gear is used for normal driving. Sports gear provides a more sensitive acceleration response and is suitable for scenarios such as overtaking. Low gear is used to provide greater torque output and is suitable for scenarios such as low-speed driving or climbing.

[0080] Optionally, before obtaining the vehicle's status parameters, parameters such as the brake pedal push rod stroke and the brake pedal's pedaling change rate are collected using devices such as displacement sensors, acceleration sensors, speed sensors, and pressure sensors installed on the brake pedal. Parameters such as the accelerator pedal push rod stroke and the accelerator pedal's pedaling change rate are collected using devices such as displacement sensors, acceleration sensors, speed sensors, and pressure sensors installed on the accelerator pedal. Motor speed is collected using devices such as motor speed sensors. The actual gear position indicated by the transmission is collected using devices such as gear sensors; alternatively, the actual gear position is obtained from the TCU (Transmission Control Unit) via the CAN (Controller Area Network) bus. The ignition switch gear position is collected using devices such as an ignition switch sensor; alternatively, the ignition switch gear position is obtained through the vehicle's power management system.

[0081] By obtaining the vehicle's status parameters, it is easy to determine the vehicle's current operating status, providing accurate data support for subsequent judgment and control.

[0082] 302. Based on the vehicle state parameters, determine whether the vehicle's operating state is any preset state.

[0083] In the embodiments of this application, the "preset state" refers to a pre-set condition used to determine whether the vehicle requires braking. This condition can be a combination or threshold based on parameters such as the travel and rate of change of the brake and accelerator pedals, motor speed, actual gear position, and ignition switch position. This condition can be determined based on actual needs and testing and is not limited here. By comparing the vehicle's current operating state with the preset state, it is possible to accurately determine whether the vehicle requires braking, thereby ensuring driving safety.

[0084] It should be noted that the preset states may include a single or multiple states, and different preset states may indicate different driving scenarios. The braking strategies corresponding to the different preset states may be the same or different, without limitation herein. For illustration, the first and second preset states correspond to the same braking strategies, as illustrated in steps 303 and 304 below, respectively.

[0085] 303. When the vehicle's operating state is the first state, activate a temporary braking function of the vehicle.

[0086] In the embodiment of the present application, the first state means that the ignition switch gear is in the on gear, the push rod stroke of the brake pedal is greater than the push rod stroke preset value, the brake pedal stepping change rate is less than the change rate preset value, the accelerator pedal push rod stroke is zero, the accelerator pedal stepping change rate is zero, the motor speed is less than the speed preset value and the actual gear is the forward gear.

[0087] In the first state, both the accelerator pedal's push rod travel and the accelerator pedal's rate of change are zero, indicating the accelerator pedal is not depressed. Forward gear is typically used to control vehicle travel on normal roads. Open gear is used to connect all vehicle circuits. Therefore, when the vehicle's operating state is in the first state, it generally indicates that the vehicle is capable of normal driving, but the driver intends to temporarily stop. Accordingly, the first state corresponds to scenarios such as stopping at a red light, pulling over, and driving in congested traffic. In these situations, the vehicle is temporarily braked.

[0088] Temporary braking is a function that is temporarily activated to slow the vehicle, stop it in the shortest possible distance, or maintain a stable speed when driving downhill. Service braking uses friction between the brake pads and the brake disc or drum to slow or stop the wheels, thereby slowing or stopping the vehicle. Accordingly, the ECU (Electronic Control Unit) sends preset commands to the service brake solenoid valve, which then generates service braking force to achieve parking.

[0089] By first activating the vehicle's temporary braking function, the vehicle speed is effectively slowed down and driving safety is ensured.

[0090] In some embodiments, temporary braking is performed to a corresponding degree based on the recommended travel range of the brake pedal push rod. Accordingly, when the vehicle is in the first operating state, a temporary braking level is determined based on the travel range of the brake pedal push rod. Different travel ranges correspond to different temporary braking levels, and the temporary braking level is positively correlated with the degree of temporary braking. Based on the temporary braking level, the temporary braking function of the vehicle corresponding to the temporary braking level is activated.

[0091] Temporary braking levels are divided into different levels based on the range of the brake pedal's push rod travel. Each temporary braking level corresponds to a different degree of braking and effect.

[0092] This approach allows for more precise control of the vehicle's braking level and effectiveness, meeting the driver's braking needs in different situations and improving the accuracy and flexibility of braking control. Precise control of braking level and effectiveness prevents over- or under-braking, reducing brake system wear and failure rates while improving driving safety.

[0093] In some embodiments, a corresponding braking function is activated when the vehicle is in a downhill state. Accordingly, when the vehicle is in a first operating state, if the push rod stroke of the brake pedal is greater than a preset push rod stroke value for a second preset time period, a vehicle slope parameter is obtained, which indicates the vehicle's inclination angle. If the slope parameter indicates that the vehicle is in a downhill state, the vehicle's downhill auxiliary braking function is activated and the temporary braking function is released.

[0094] The slope parameter indicates the vehicle's current slope or inclination angle. The slope parameter can be measured by the vehicle's sensors, such as accelerometers and gyroscopes. Downhill assist braking automatically adjusts the braking force when the vehicle is traveling downhill to prevent acceleration due to gravity.

[0095] By activating the downhill assist braking function when the vehicle is traveling downhill, it automatically adjusts braking force to prevent the vehicle from accelerating downward due to gravity, thereby improving downhill driving safety and stability. Through intelligent braking control strategies, the braking force and effect are automatically adjusted based on the driver's needs and the vehicle's operating status, improving driving convenience.

[0096] 304. When the vehicle's operating state is the second state, activate a temporary braking function of the vehicle.

[0097] In the embodiment of the present application, the second state means that the ignition switch gear is in the on gear, the push rod stroke of the brake pedal is zero, the brake pedal stepping change rate is zero, the push rod stroke of the accelerator pedal is zero, the accelerator pedal stepping change rate is zero, the motor speed is not zero and the actual gear is non-parking gear.

[0098] In the second state, the push rod stroke of the brake pedal and the rate of change of the brake pedal are both zero, indicating that the brake pedal is not being stepped on; the push rod stroke of the accelerator pedal and the rate of change of the accelerator pedal are both zero, indicating that the accelerator pedal is not being stepped on. The motor speed is not zero, indicating that the motor is running or in working condition and is providing power. In one possible case, the motor speed is getting faster and faster. The parking gear can be used to lock the axle when the vehicle is stationary on a slope. The non-parking gear refers to the actual gear corresponding to the transmission other than the parking gear. The non-parking gear indicates that the vehicle has not locked the axle. Therefore, when the vehicle's operating state is the second state, it usually means that the vehicle is in a slipping state. At this time, the vehicle is temporarily braked.

[0099] By first activating the vehicle's temporary braking function, the vehicle speed is effectively slowed down and driving safety is ensured.

[0100] 305. When the duration of the vehicle executing the temporary braking function exceeds a first preset duration, the parking brake function of the vehicle is activated and the temporary braking function is released.

[0101] In this embodiment of the present application, the first preset duration refers to a pre-set time threshold for determining whether the vehicle needs to switch from temporary braking to parking braking. The parking brake function is a braking function activated for long-term parking. The parking brake locks the vehicle's drive shaft or rear wheels and is typically used to prevent the vehicle from moving when stationary.

[0102] By automatically switching to the parking brake function, the vehicle is ensured to stop stably, while by releasing the temporary braking function, unnecessary energy consumption and wear are avoided.

[0103] In some embodiments, when the vehicle is performing a temporary braking function, if a first preset parameter is not zero, the temporary braking function is released, and the first preset parameter includes at least one of the push rod stroke of the brake pedal, the pedaling change rate of the brake pedal, the push rod stroke of the accelerator pedal, and the pedaling change rate of the accelerator pedal.

[0104] When the vehicle is in a temporary braking state within a first preset time period, if at least one of the push rod stroke of the brake pedal and the rate of change of the brake pedal is not zero, it means that the brake pedal of the vehicle is stepped on, which means that the driver needs to stop temporarily or the vehicle is in a slipping state, and the driver has taken braking measures at this time, so the temporary braking is released; if at least one of the push rod stroke of the accelerator pedal and the rate of change of the accelerator pedal is not zero, it means that the accelerator pedal of the vehicle is stepped on, which means that the driver has no intention of stopping temporarily and still needs to accelerate the vehicle, and the temporary braking is released at this time.

[0105] This approach allows the vehicle to respond promptly and activate or deactivate the temporary braking function in a variety of scenarios, providing greater convenience and improved safety. For example, the system can respond promptly when the driver alternates between pressing the brake and accelerator pedals while driving in congested traffic or following a vehicle.

[0106] 306. When the vehicle's operating state is the third state, activate the parking brake function.

[0107] In the embodiment of the present application, the third state refers to the ignition switch position being in the off position, the motor speed being non-zero, and the actual gear being a non-parking position. In the third state, the off position is the position in which the entire vehicle is powered off. The actual gear position is not in the park position, indicating that the vehicle is not parked. In this case, the motor speed is non-zero, indicating that the vehicle is unmanned and rolling. At this point, the vehicle is parked. The parking brake locks the vehicle's drive shaft or rear wheels, providing resistance to the vehicle when parked and preventing it from rolling.

[0108] By switching to the parking brake function, the vehicle is ensured to stop stably. At the same time, by releasing the temporary brake function, unnecessary energy consumption and wear are avoided. This approach reduces the driver's operational burden in heavy traffic or when parking, improving the driving experience and enhancing driving safety.

[0109] In some embodiments, when the vehicle is performing the parking brake function, if the second preset parameter is not zero, the parking brake function is released, and the second preset parameter is at least one of the push rod stroke of the accelerator pedal and the accelerator pedal depression change rate.

[0110] When the vehicle is in a state of temporary braking, if the push rod stroke of the accelerator pedal and the rate of change of the accelerator pedal are not zero, it means that the accelerator pedal of the vehicle is stepped on, which means that the driver needs to control the vehicle to start, and the parking brake is released at this time. Normally, the release of the parking brake function means that the vehicle exits the Auto Hold function and enters the Standby state. Among them, Standby usually refers to the low-power standby state of the vehicle. Optionally, the condition for releasing the parking brake can also be set to that the push rod stroke of the accelerator pedal is greater than the corresponding preset value, which is not restricted here.

[0111] Through the above method, the vehicle can quickly respond to the driver's operation of the accelerator pedal to start the vehicle, thereby improving the driving experience.

[0112] In some embodiments, when the vehicle's operating state is in the third state, an abnormality prompt function of the vehicle is activated, and the prompt function is used to prompt the vehicle to be in an abnormal state through sound and light prompts. For example, a red indicator light on the vehicle's dashboard lights up, or the vehicle emits a continuous alarm sound.

[0113] Through the above method, the driver or other personnel can be promptly reminded that the vehicle is in an abnormal state, thereby improving intelligence and ensuring safety.

[0114] To describe the overall process of the automatic parking method, see Figure 4 As shown, Figure 4This is a schematic diagram of an overall process provided by an embodiment of the present application. First, the state parameters of the vehicle are collected in real time. Then, the state of the vehicle's ignition switch is determined. When the vehicle's ignition switch is in the off position, if the motor speed is not zero and the actual gear is not the parking gear, it means that the vehicle is in a rolling state at this time, and the parking brake function is activated. When the vehicle's ignition switch is in the on position, the vehicle's operating state is determined. When the vehicle's operating state is the first state or the second state, the temporary braking function is activated. When the duration of the temporary braking exceeds the first preset duration, the parking brake function is activated. Among them, the first state refers to the ignition switch gear being the on gear, the push rod stroke of the brake pedal being greater than the push rod stroke preset value, the brake pedal's stepping change rate being less than the change rate preset value, the accelerator pedal's push rod stroke being zero, the accelerator pedal's stepping change rate being zero, the motor speed being less than the speed preset value, and the actual gear being the forward gear. The second state means that the ignition switch gear is on, the brake pedal push rod stroke is zero, the brake pedal stepping change rate is zero, the accelerator pedal push rod stroke is zero, the accelerator pedal stepping change rate is zero, the motor speed is not zero and the actual gear is non-parking gear.

[0115] Specifically, the system first collects vehicle status parameters in real time, including brake pedal push rod travel, brake pedal depression rate of change, accelerator pedal push rod travel, accelerator pedal depression rate of change, motor speed, actual gear position, and ignition switch position. The system then analyzes these parameters to determine whether the driver intends to stop the vehicle temporarily, whether the vehicle is rolling, or whether the vehicle is rolling without a driver. If the driver intends to stop the vehicle temporarily or the vehicle is rolling, the system applies the temporary brake. If the temporary brake lasts longer than a preset time, the parking brake is applied and the temporary brake is released. If the vehicle is in the temporary brake state and the brake pedal or accelerator pedal is depressed, the temporary brake is released. If the vehicle is rolling without a driver, the parking brake is applied.

[0116] The embodiment of the present application provides an automatic parking control method, which reduces the driver's operating load, effectively reduces the probability of accidents, and improves driving safety. In this method, the operating state of the vehicle can be determined by obtaining the vehicle's state parameters, so that when the vehicle's operating state is any preset state, the vehicle's temporary braking function is activated according to a preset strategy, and when the vehicle performs the temporary braking function for a period exceeding a first preset time, the vehicle's parking brake function is activated. Since the vehicle's state parameters include multiple parameters such as the brake pedal push rod stroke, the brake pedal's stepping change rate, the accelerator pedal push rod stroke, the accelerator pedal's stepping change rate, the motor speed, the actual gear position, and the ignition switch gear position, the current vehicle's operating state and corresponding scenarios can be accurately determined, thereby enabling the vehicle to adopt a corresponding braking strategy, thereby better adapting to a variety of complex scenarios and dynamic conditions, and having high flexibility.

[0121] The control module 503 is further configured to activate the parking brake function of the vehicle and release the temporary braking function when the duration of the temporary braking function of the vehicle exceeds a first preset duration.

[0122] In some embodiments, the control module 503 is used to start the temporary braking function of the vehicle when the vehicle's operating state is a first state, wherein the first state is that the ignition switch gear is in the on gear, the push rod stroke of the brake pedal is greater than the push rod stroke preset value, the brake pedal's stepping change rate is less than the change rate preset value, the accelerator pedal's push rod stroke is zero, the accelerator pedal's stepping change rate is zero, the motor speed is less than the speed preset value and the actual gear is the forward gear.

[0123] In some embodiments, the control module 503 is also used to determine the temporary braking level based on the push rod stroke range of the brake pedal when the vehicle's operating state is the first state, different push rod stroke ranges correspond to different temporary braking levels, and the temporary braking level is positively correlated with the temporary braking degree; based on the temporary braking level, the temporary braking function of the vehicle corresponding to the temporary braking level is started.

[0124] In some embodiments, the control module 503 is also used to obtain the slope parameter of the vehicle if the push rod stroke of the brake pedal is greater than the preset push rod stroke value within a second preset time period when the vehicle's operating state is the first state, and the slope parameter is used to indicate the inclination angle of the vehicle; when the slope parameter indicates that the vehicle is in a downhill state, the vehicle's downhill auxiliary braking function is started and the temporary braking function is released.

[0125] In some embodiments, the control module 503 is used to start the temporary braking function of the vehicle when the vehicle's operating state is a second state, wherein the second state is that the ignition switch gear is on, the push rod stroke of the brake pedal is zero, the brake pedal's stepping change rate is zero, the accelerator pedal's push rod stroke is zero, the accelerator pedal's stepping change rate is zero, the motor speed is not zero and the actual gear is a non-parking gear.

[0126] In some embodiments, the control module 503 is also used to release the temporary braking function when the vehicle is performing the temporary braking function if the first preset parameter is not zero. The first preset parameter includes at least one of the push rod stroke of the brake pedal, the pedaling change rate of the brake pedal, the push rod stroke of the accelerator pedal, and the pedaling change rate of the accelerator pedal.

[0127] In some embodiments, the control module 503 is further used to release the parking brake function when the vehicle is executing the parking brake function if a second preset parameter is not zero, and the second preset parameter is at least one of the push rod stroke of the accelerator pedal and the pedaling change rate of the accelerator pedal.

[0128] In some embodiments, the control module 503 is further used to activate the parking brake function when the vehicle's operating state is a third state, where the ignition switch gear is in the off gear, the motor speed is not zero, and the actual gear is a non-parking gear.

Thus, when the vehicle's operating state is any preset state, the vehicle's temporary braking function is activated according to a preset strategy. Furthermore, when the vehicle executes the temporary braking function for a period exceeding a first preset duration, the vehicle's parking brake function is activated. Because the vehicle's state parameters include multiple parameters such as brake pedal push rod travel, brake pedal depression rate of change, accelerator pedal push rod travel, accelerator pedal depression rate of change, motor speed, actual gear position, and ignition switch position, the device can accurately determine the vehicle's current operating state and corresponding scenarios, enabling the vehicle to adopt a corresponding braking strategy, thereby better adapting to a variety of complex scenarios and dynamic conditions and providing greater flexibility.
