[0027] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0028] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect.

[0029] With the development of the vehicle industry, vehicles are increasingly involved in our daily lives and work. Vehicle safety has become a major concern. Vehicles may face emergencies such as wading through water in the wild and urban flooding. Some vehicles have developed a floating mode. In this mode, the vehicle can move forward, backward and turn by differential control of the four wheels, which can provide effective escape and self-rescue capabilities in emergency situations.

[0030] Typically, after a vehicle has driven through water, sensors detect that the water depth, vehicle posture, and wheel slippage conditions meet the criteria for buoyancy, and the vehicle automatically activates buoyancy mode. In buoyancy mode, the vehicle usually closes its windows and opens its sunroof. The driver can control the vehicle's movement using the accelerator and steering wheel, but the speed is relatively slow. In buoyancy mode, due to the buoyancy of the water, the wheels cannot make contact with the ground or have a very small contact area. Therefore, the acceleration / braking performance achieved solely by the wheel hub motors is poor, and the vehicle struggles to maintain its direction of motion in flowing water. Therefore, there is an urgent need for a vehicle auxiliary control method in buoyancy mode.

[0031] The following describes specific embodiments in conjunction with... Figures 1 to 3 The technical solution of this application will be described in detail below.

[0032] Some embodiments of this application provide a vehicle auxiliary control method, such as Figure 1 As shown, it includes the following steps:

[0033] S1. Obtain the current target mode status of the vehicle.

[0034] The vehicle's onboard unit can obtain the vehicle's current target mode status. The target mode is floating mode, which is activated when the vehicle has waded through water and the sensors detect that the wading depth and other conditions meet the floating conditions. In floating mode, the vehicle will close the windows and open the sunroof, and the driver can control the vehicle to move in the water using the accelerator and steering wheel. The target mode status is, for example, on or off.

[0035] S2. When the target mode is enabled, the current accelerator pedal state and brake pedal state of the vehicle are obtained.

[0036] The vehicle's onboard unit can obtain the current status of the accelerator pedal and brake pedal. The pedal status is, for example, whether it is pressed or not pressed. Pressing the pedal means that the vehicle needs to accelerate or brake, while not pressing the pedal means that the vehicle needs to stop accelerating or braking.

[0037] S3. When the accelerator pedal or brake pedal is in the depressed state, the vehicle's cooling fan is turned on to allow fluid to flow within the vehicle, assisting the vehicle in acceleration or braking.

[0038] In floating mode, the vehicle is partially submerged in water or other fluids. At this point, water enters the cooling fan through the air intake grille in the front engine compartment. Once in floating mode, if the brake or accelerator pedal is pressed, it indicates the vehicle needs to accelerate or brake. The onboard unit activates the cooling fan, directing fluid flow towards the front or rear of the vehicle to provide power or resistance, assisting in acceleration or braking. The fan, in conjunction with the wheel hub motors to drive the wheels for acceleration or braking, improves the vehicle's overall acceleration / braking performance with high resource utilization. In emergencies such as wheel hub motor failure, the fan can also provide power or resistance independently to help the user get out of trouble. Furthermore, the cooling fan operation accelerates the removal of mud and sand from the engine compartment, facilitating subsequent vehicle cleaning.

[0039] This vehicle auxiliary control method is simple and convenient, and can effectively assist the vehicle in accelerating or braking in floating mode. It has high resource utilization, good user experience, and high safety, and can provide users with more effective escape and self-rescue capabilities in emergency situations.

[0040] In some embodiments, turning on the vehicle's cooling fan when the accelerator pedal or brake pedal is in a depressed state includes:

[0041] S301. When the accelerator pedal is in the depressed state and the brake pedal is in the undepressed state, the cooling fan is turned on and operates in the first mode; wherein, in the first mode, the flow direction of the fluid is opposite to the driving direction of the vehicle.

[0042] When the accelerator pedal is depressed and the brake pedal is not depressed, it means that the vehicle needs to accelerate. At this time, the cooling fan is controlled to operate in the first mode, so that the water flows in the opposite direction of the vehicle's travel. Under the reaction force of the water flow, it provides power assistance for acceleration.

[0043] S302. When the accelerator pedal is in an unpressed state and the brake pedal is in a pressed state, the cooling fan is turned on and operates in the second mode; wherein, in the second mode, the flow direction of the fluid is the same as the driving direction of the vehicle.

[0044] When the accelerator pedal is not pressed and the brake pedal is pressed, it means that the vehicle needs to brake. At this time, the cooling fan is controlled to operate in the second mode, so that the water flow is in the same direction as the vehicle's travel. Under the reaction force of the water flow, it provides resistance to assist braking.

[0045] In some embodiments, the step of activating the vehicle's cooling fan when the accelerator pedal or brake pedal is depressed further includes:

[0046] S303. When both the accelerator pedal and the brake pedal are in the depressed state, the cooling fan is turned on and operates in the second mode.

[0047] The accelerator pedal and brake pedal are both in the depressed state. This may be due to user error, causing the accelerator pedal and brake pedal to be depressed at the same time. In this case, to ensure user safety, the cooling fan can be controlled to operate in the second mode, so that the water flow is in the same direction as the vehicle's travel, thereby providing resistance to assist braking.

[0048] In some embodiments, turning on the cooling fan to operate in a first mode includes:

[0049] S3011. Obtain the current gear of the vehicle.

[0050] The vehicle's onboard unit can obtain the vehicle's current gear position, such as forward or reverse.

[0051] S3012. When the gear is forward, the motor of the cooling fan is controlled to rotate in the forward direction. When the motor rotates in the forward direction, the fluid flows towards the rear of the vehicle.

[0052] When the current gear is forward, it means the vehicle is moving forward. At this time, the motor controlling the cooling fan rotates in the forward direction, and the fan blades drive the water flow towards the rear of the vehicle. Under the reaction force of the water flow, the vehicle is propelled forward, assisting the vehicle in accelerating.

[0053] S3013. When the gear is reverse gear, the motor is controlled to rotate in the reverse direction. When the motor rotates in the reverse direction, the fluid flows towards the front of the vehicle.

[0054] When the current gear is reverse, it means the vehicle is moving backward towards the rear. At this time, the motor controlling the cooling fan rotates in the opposite direction, and the fan blades drive the water flow towards the front of the vehicle. Under the reaction force of the water flow, the vehicle is pushed backward towards the rear, assisting the vehicle in accelerating.

[0055] By changing the direction of the motor, the direction of the water flow can be controlled, thereby assisting the vehicle in accelerating, which is simple and convenient.

[0056] In some embodiments, turning on the cooling fan to operate in a second mode includes:

[0057] S3021. Obtain the current gear of the vehicle.

[0058] The vehicle's onboard unit can obtain the vehicle's current gear position, such as forward or reverse.

[0059] S3022. When the gear is forward, the motor is controlled to rotate in the reverse direction.

[0060] When the current gear is forward, it means the vehicle is moving in the direction of the front. At this time, the motor controlling the cooling fan rotates in the opposite direction, and the fan blades drive the water flow towards the front of the vehicle. Under the reaction force of the water flow, the vehicle is hindered from moving in the direction of the front, thus assisting in braking.

[0061] S3023. When the gear is reverse gear, the motor is controlled to rotate in the forward direction.

[0062] When the current gear is reverse, it means the vehicle is moving backward towards the rear. At this time, the motor controlling the cooling fan rotates in the forward direction, and the fan blades drive the water flow towards the rear of the vehicle. Under the reaction force of the water flow, the vehicle is prevented from moving backward towards the rear, thus assisting in braking.

[0063] By changing the direction of the motor, the direction of water flow can be controlled, thereby assisting in vehicle braking, which is simple and convenient.

[0064] In some embodiments, the vehicle auxiliary control method further includes:

[0065] S4. When a motor direction switching command is received, the motor is controlled to gradually decrease in speed from the current rotation direction to a stop, and then the motor is controlled to gradually increase in speed from a stop to the target speed in the opposite rotation direction.

[0066] When using the vehicle in floating mode, there will be situations where the motor direction needs to be switched, such as when the vehicle is switching between forward and reverse gears, or between acceleration and braking. According to the aforementioned control method, this will cause the motor direction to change, so as to change the direction of water flow.

[0067] When the vehicle's main unit receives a pedal switching command or a gear shifting command, it can generate a motor steering switching command and send it to the cooling fan motor. In order to avoid sudden motor stops or frequent steering changes, the motor can be controlled to gradually decrease in speed from the current rotation direction to a stop, and then controlled to gradually increase in speed from a stop to the target speed in the opposite rotation direction, so as to ensure smooth motor switching, improve service life and safety.

[0068] The target rotational speed can be a preset fixed value or proportional to the pedal opening; there is no specific limitation. Gradual rotation to increase or decrease the speed can be achieved by changing the rotational speed according to a fixed rate of change, etc., and there is no specific limitation; calibration should be based on actual user experience. For example, controlling the motor to rotate forward from 1000 r / min to 0 r / min within 10 seconds, with a rate of change of -100 r / s; then controlling the motor to rotate in the reverse direction from 0 r / min to 500 r / min within 10 seconds, with a rate of change of 50 r / s.

[0069] In some embodiments, turning on the cooling fan to operate in a first mode includes:

[0070] S3014. Obtain the current accelerator pedal opening of the vehicle.

[0071] The vehicle's onboard unit can obtain the current accelerator pedal opening of the vehicle. The range of accelerator pedal opening is, for example, from 0% to 100%, where 0% represents the accelerator pedal being fully released and 100% represents the accelerator pedal being fully depressed.

[0072] S3015. When the accelerator pedal opening is greater than or equal to the first preset opening and continues for more than the first preset time, the cooling fan is turned on and operates in the first mode.

[0073] The first preset opening degree is, for example, 5%, 6%, or 7%, and the first preset time is, for example, 0s, 5s, or 10s, etc., without any specific limitation. When the accelerator pedal opening degree is greater than or equal to the first preset opening degree and continues to exceed the first preset time, it means that the user urgently needs to accelerate. At this time, turning on the cooling fan to operate in the first mode can improve the user experience and save energy.

[0074] In some embodiments, turning on the cooling fan to operate in a second mode includes:

[0075] S3024. Obtain the current brake master cylinder pressure of the vehicle.

[0076] The onboard unit can obtain the current brake master cylinder pressure of the vehicle. The range of brake master cylinder pressure is, for example, from 0 bar to 100 bar, where 0 bar represents the brake pedal being fully released and 100 bar represents the brake pedal being fully depressed.

[0077] S3025. When the pressure of the brake master cylinder is greater than or equal to the first preset pressure and continues for more than the second preset time, the cooling fan is turned on and operates in the second mode.

[0078] The first preset pressure is, for example, 5 bar, 6 bar, or 7 bar, and the second preset time is, for example, 0 seconds, 5 seconds, or 10 seconds, etc., without specific limitations. When the brake master cylinder pressure is greater than or equal to the first preset pressure and continues to exceed the second preset time, it indicates that the user urgently needs to brake. At this time, the cooling fan is turned on to operate in the second mode, which can improve the user experience and save energy.

[0079] In some embodiments, turning on the cooling fan to operate in a first mode includes:

[0080] S3016. Turn on the cooling fan and operate it at a first speed in the first mode, wherein the first speed is positively correlated with the opening of the accelerator pedal.

[0081] The first RPM is positively correlated with the current accelerator pedal opening. That is, the larger the current accelerator pedal opening, the higher the first RPM, which provides more power and matches the user's acceleration needs at this time, thus improving the user experience.

[0082] Specifically, the first speed is n1, Nmax is the maximum speed of the cooling fan, Va is the current accelerator pedal opening, V is the first preset opening, and Vmax is the maximum opening of the accelerator pedal. For example, n1 = Nmax * (Va - V) / Vmax is satisfied so that the cooling fan can gradually increase its speed after the current accelerator pedal opening exceeds the first preset opening.

[0083] In some embodiments, turning on the cooling fan to operate in a second mode includes:

[0084] S3026. Turn on the cooling fan and operate it at the second speed in the second mode. The second speed is positively correlated with the pressure of the brake master cylinder.

[0085] The second rotational speed is positively correlated with the current master cylinder pressure. That is, the higher the current master cylinder pressure, the higher the second rotational speed, which in turn provides greater resistance, matching the user's braking needs at that moment and improving the user experience.

[0086] Specifically, the second rotational speed is n2, Nmax is the maximum rotational speed of the cooling fan, Pa is the current brake master cylinder pressure, P is the first preset pressure, and Pmax is the maximum brake master cylinder pressure. For example, n2 = Nmax * (Pa - P) / Pmax is satisfied so that after the current brake master cylinder pressure exceeds the first preset pressure, the cooling fan can gradually increase its rotational speed.

[0087] In some embodiments, turning on the vehicle's cooling fan includes:

[0088] S300. Open the vehicle's air intake grille to its maximum opening and turn on the cooling fan.

[0089] Before turning on the cooling fan, open the air intake grille to its maximum opening. This ensures smooth water flow and does not obstruct the cooling fan's power delivery or create resistance, thus ensuring the vehicle's improved acceleration and braking performance.

[0090] In some embodiments, the vehicle auxiliary control method further includes:

[0091] S4. When the accelerator pedal state or the brake pedal state changes from being pressed to being unpressed, the cooling fan is turned off.

[0092] When the pedal is switched from being pressed to being released, it means that the user needs to stop accelerating or braking. At this point, the cooling fan is turned off, the auxiliary control functions are turned off, and energy efficiency is improved.

[0093] In some embodiments, the step of turning on the cooling fan to operate in a first mode includes:

[0094] S401. When the accelerator pedal opening is less than or equal to the second preset opening, the cooling fan is turned off; wherein the second preset opening is less than the first preset opening.

[0095] The second preset opening degree is, for example, 2%, 3%, or 4%, etc., and is not specifically limited. When the accelerator pedal opening degree is less than or equal to the second preset opening degree, it means that the user needs to stop accelerating. At this time, the cooling fan is turned off to stop the auxiliary acceleration, which can save energy. The second preset opening degree is less than the first preset opening degree, which can avoid the auxiliary acceleration function from frequently entering or exiting, realize hysteresis control, avoid function jumps, improve user experience, and ensure performance.

[0096] In some embodiments, the step of turning on the cooling fan to operate in a second mode includes:

[0097] S402. When the pressure of the brake master cylinder is less than or equal to the second preset pressure, the cooling fan is turned off; wherein the second preset pressure is less than the first preset pressure.

[0098] The second preset pressure is, for example, 2 bar, 3% bar, or 4 bar, etc., and is not specifically limited. When the brake master cylinder pressure is less than or equal to the second preset pressure, it means the user needs to stop braking. At this time, the cooling fan is turned off to stop auxiliary braking, which can save energy. The second preset pressure is less than the first preset pressure, which can avoid the auxiliary braking function from frequently entering or exiting, realizing hysteresis control, avoiding function jumps, improving user experience, and ensuring performance.
