[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0036] See also Figure 1 , Figure 1 The flowchart of a method for controlling an electric rear wing that adjusts the angle according to the vehicle body state is provided in an embodiment of the present invention. Figure 1 As shown, the method includes but is not limited to the following steps:
[0037] S1. Obtain vehicle speed information, vehicle load information and slope information;
[0038] S2. Determine a first angle value according to the vehicle speed information and the pre-stored angle value of the electric rear wing corresponding to the vehicle speed, and compensate and adjust the first angle value according to the vehicle load information and / or the slope information to obtain a final angle value;
[0039] S3. Adjust the electric tail wing angle according to the final angle value.
[0040] Specifically, a vehicle load sensor is provided at the connection of the four wheels of the vehicle to obtain the vehicle load information, a vehicle speed sensor is provided to obtain the vehicle speed information, and a vehicle slope sensor is provided to obtain the slope information. The body control module (BCM) receives and processes the vehicle speed information, and feeds the information back to the VIU at the rear of the vehicle. The VIU controls the operation of the electric motor; the BCM of the vehicle receives the vehicle load sensor signal, analyzes the load size of the vehicle when driving, and sends the analysis result to the VIU at the rear of the vehicle. The rear VIU software makes compensation adjustment to the opening angle of the tail wing based on the conventional opening angle according to the calibration result and the received signal. The tail wing motor rotates and runs different hall numbers through different angle instructions, thereby realizing the adjustment of the electric tail wing with the load of the vehicle; the BCM of the vehicle receives the vehicle slope sensor signal, analyzes the slope size of the vehicle when driving, and when the duration in this slope interval exceeds the preset value, the electric tail wing enters the slope compensation working condition.
[0041] In some embodiments, determining the first angle value according to the preset angle value of the electric rear wing corresponding to the vehicle speed information includes:
[0042] A speed range in which the current speed of the vehicle is located is determined, and a first angle value is determined according to the speed range and a pre-stored angle value of the electric rear wing corresponding to the vehicle speed.
[0043] It is worth noting that in some instances, when the vehicle speed is between 60 and 80 km / h, the tail wing angle is adjusted to a preset angle β0; when the vehicle speed is between 80 and 100 km / h, the tail wing angle is adjusted to a preset angle β1; when the vehicle speed is between 100 and 120 km / h, the tail wing angle is adjusted to a preset angle β2; when the vehicle speed is greater than 120 km / h, the tail wing angle is adjusted to a preset angle β3.
[0044] According to aerodynamics, a car generates lift when it moves: F 升 =k 升 ρv 2 S 车 , where k 升 is the lift coefficient, ρ is the air density, v is the vehicle speed, S 车 is the reference area of the vehicle. After the vehicle design is completed, the above parameters have basically remained unchanged except for the speed variable.
[0045] Downforce generated by the rear wing: F 压 =k 压 ρv 2 S 翼 , where k 压 Provides downforce coefficient for the rear wing, ρ is air density, v is vehicle speed, S 翼 is the reference area of the tail wing. After the above parameters are designed and arranged, the downforce coefficient provided by the electric tail wing can also change with the opening angle β of the tail wing, such as Figure 2 As shown in the figure, the specific curve is obtained from the tail wind tunnel test measurement. The pressure coefficient generated by the tail is 0~ β L The range is approximately proportional, exceeding β L After reaching the range, the pressure coefficient first decreases slowly and then drops sharply. β0 is the initial lifting angle of the tail wing.
[0046] The present invention converts β0 to β L Divide it into 7 parts, and use the exponential relationship 1, 2, 4 to set the tail angle of attack gradient:
[0047] β1=(β L- β0) / 7
[0048] β2=(β L -β0) / 7+(β L- β0) / 7*2=3*(β L -β0) / 7
[0049] β3=β L
[0050] In some embodiments, the compensating adjustment of the first angle value according to the vehicle load information includes:
[0051] Determine the load range in which the current load of the vehicle is located, adjust the first angle value according to the load range and the pre-stored compensation angle value of the electric rear wing corresponding to the vehicle load to form a second angle value, and the second angle value is the final angle value.
[0052] Specifically, the vehicle load sensor is set at the connection of the four wheels of the vehicle. The vehicle BCM receives the vehicle load sensor signal and analyzes the load size of the vehicle when driving. The BCM sends the analysis result to the VIU at the rear of the vehicle. The rear VIU software makes compensation adjustments to the tail wing opening angle based on the conventional opening angle according to the calibration results and the received signal. The tail wing motor rotates and runs different hall numbers through different angle instructions, thereby adjusting the electric tail wing with the load of the whole vehicle. Under this load compensation condition, according to the calibration, the vehicle load is set to several levels. When the setting is ≥150kg, the load compensation is started. For every increase of 100kg, a compensation adjustment parameter is updated according to the aerodynamic calibration.
[0053] When the vehicle load increases, on the one hand, the load causes the vehicle body posture to be lower, which improves the driving stability. On the other hand, the load will also increase the downforce of the vehicle on the ground and increase the vehicle adhesion. When the vehicle detects that the load size exceeds a certain value (such as more than 150kg), and the vehicle speed reaches the driving speed of each stage of the first working condition, the adjustment of the rear wing angle is corrected based on the above β0~β3. At this time, the actual rear wing adjustment angle = c*β n , c is the load correction factor, which has a value less than or equal to 1 and is determined based on the vehicle wind tunnel test under load conditions.
[0054] In some embodiments, the compensating and adjusting the first angle value according to the slope information further includes:
[0055] Determine the slope interval where the slope of the vehicle's current position is located, and adjust the first angle value according to the slope interval and the pre-stored compensation angle value of the electric rear wing corresponding to the slope of the vehicle's current position to form a third angle value, which is the final angle value.
[0056] In some embodiments, the compensating and adjusting the first angle value according to the slope information further includes:
[0057] Determine the slope interval where the slope of the vehicle's current position is located, adjust the second angle value according to the slope interval and the pre-stored compensation angle value of the electric rear wing corresponding to the slope of the vehicle's current position to form a fourth angle value, and the fourth angle value is the final angle value.
[0058] Through the vehicle slope sensor installed at the connection of the four wheels of the vehicle. The vehicle BCM receives the vehicle slope sensor signal, analyzes the slope size of the vehicle when driving, and when the duration in this slope range exceeds 5s, the electric tail wing enters the slope compensation condition. The BCM sends the slope signal to the VIU at the rear of the vehicle. The rear VIU software makes slope compensation for the tail wing opening angle based on the conventional opening angle according to the calibration results and the received signal. The tail wing motor rotates and runs different hall numbers through different angle instructions, thereby adjusting the electric tail wing with the load of the whole vehicle. Under this slope compensation condition, according to the calibration, the slope of the whole vehicle is set to several levels. When the setting is ≥5%, the slope compensation is started. Every 5% increase is updated according to the aerodynamic calibration. A compensation adjustment parameter is updated.
[0059] When the vehicle detects that it is driving on a long downhill road with a slope of ≥5%, the tail angle is directly adjusted to β L The value can improve braking performance by increasing the downforce of the rear wing. On the other hand, the windward angle of the rear wing increases, and the air resistance generated by the rear wing itself also increases, which is conducive to reducing the vehicle speed. This mode triggers adjustment: you can use the slope sensor at the tire, or you can use the road conditions in the car or mobile phone navigation to enter the long downhill road condition for automatic adjustment.
[0060] like Figure 3 As shown, in some embodiments, the compensating and adjusting the first angle value according to the vehicle load information and the slope information to determine the final angle value also includes:
[0061] When the speed information, load information or slope information exceeds a preset departure threshold, the electric tail wing angle is adjusted according to the information.
[0062] Specifically, of the three adjustment modes, the speed adjustment mode is triggered first. Speed is a prerequisite for the tail wing to open. The tail wing will only open when the speed is greater than the set value, such as setting the electric tail wing to open at 60km / h. At the same time, when the vehicle speed reaches the tail wing opening trigger condition, VIU first obtains the vehicle load information from the vehicle, and directly adds the load correction factor when adjusting the tail wing opening along with the speed. When the vehicle is detected to be on a long downhill road condition and the speed is greater than the starting speed of 60km / h, the tail wing is directly adjusted to β L .
[0063] The electric rear wing control method of the present invention, which adjusts the angle according to the vehicle body state, obtains vehicle speed information, vehicle load information and slope information; determines a first angle value according to the vehicle speed information and the pre-stored angle value of the electric rear wing corresponding to the vehicle speed, and compensates and adjusts the first angle value according to the vehicle load information and / or the slope information to obtain a final angle value; and adjusts the electric rear wing angle according to the final angle value. The electric rear wing can be used to conveniently adjust the rear wing angle at any time, maximizing the effect of the rear wing on improving vehicle driving stability and reducing energy consumption under various working conditions.
[0064] See also Figure 4 The embodiment of the present invention further provides an electric rear wing control device for adjusting the angle according to the vehicle body state, comprising:
[0065] A collection unit, used to obtain vehicle speed information, vehicle load information and slope information;
[0066] a calculation unit, configured to determine a first angle value according to the vehicle speed information and a pre-stored angle value of the electric rear wing corresponding to the vehicle speed, and to compensate and adjust the first angle value according to the vehicle load information and / or the slope information to obtain a final angle value;
[0067] The adjusting unit is used to adjust the electric tail wing angle according to the final angle value.
[0068] Specifically, a vehicle load sensor is provided at the connection of the four wheels of the vehicle to obtain the vehicle load information, a vehicle speed sensor is provided to obtain the vehicle speed information, and a vehicle slope sensor is provided to obtain the slope information. The body control module (BCM) receives and processes the vehicle speed information, and feeds the information back to the VIU at the rear of the vehicle. The VIU controls the operation of the electric motor; the BCM of the vehicle receives the vehicle load sensor signal, analyzes the load size of the vehicle when driving, and sends the analysis result to the VIU at the rear of the vehicle. The rear VIU software makes compensation adjustment to the opening angle of the tail wing based on the conventional opening angle according to the calibration result and the received signal. The tail wing motor rotates and runs different hall numbers through different angle instructions, thereby realizing the adjustment of the electric tail wing with the load of the vehicle; the BCM of the vehicle receives the vehicle slope sensor signal, analyzes the slope size of the vehicle when driving, and when the duration in this slope interval exceeds the preset value, the electric tail wing enters the slope compensation working condition.
[0069] In some embodiments, the calculation unit is further configured to determine a first angle value according to a preset angle value of the electric rear wing corresponding to the vehicle speed information, including:
[0070] A speed range in which the current speed of the vehicle is located is determined, and a first angle value is determined according to the speed range and a pre-stored angle value of the electric rear wing corresponding to the vehicle speed.
[0071] It is worth noting that in some instances, when the vehicle speed is between 60 and 80 km / h, the tail wing angle is adjusted to a preset angle β0; when the vehicle speed is between 80 and 100 km / h, the tail wing angle is adjusted to a preset angle β1; when the vehicle speed is between 100 and 120 km / h, the tail wing angle is adjusted to a preset angle β2; when the vehicle speed is greater than 120 km / h, the tail wing angle is adjusted to a preset angle β3.
[0072] According to aerodynamics, a car generates lift when it moves: F 升 =k 升 ρv 2 S 车 , where k 升 is the lift coefficient, ρ is the air density, v is the vehicle speed, S 车 is the reference area of the vehicle. After the vehicle design is completed, the above parameters have basically remained unchanged except for the speed variable.
[0073] Downforce generated by the rear wing: F 压 =k 压 ρv 2 S 翼 , where k 压 Provides downforce coefficient for the rear wing, ρ is air density, v is vehicle speed, S 翼 is the reference area of the tail wing.

The pressure coefficient generated by the tail is 0~ β L The range is approximately proportional, exceeding β L After reaching the range, the pressure coefficient first decreases slowly and then drops sharply. β0 is the initial lifting angle of the tail wing.
[0074] The present invention converts β0 to β L Divide it into 7 parts, and use the exponential relationship 1, 2, 4 to set the tail angle of attack gradient:
[0075] β1=(β L- β0) / 7
[0076] β2=(β L -β0) / 7+(β L- β0) / 7*2=3*(β L- β0) / 7
[0077] β3=β L
[0078] In some embodiments, the calculation unit is further configured to perform compensation adjustment on the first angle value according to the vehicle load information, including:
[0079] Determine the load range in which the current load of the vehicle is located, adjust the first angle value according to the load range and the pre-stored compensation angle value of the electric rear wing corresponding to the vehicle load to form a second angle value, and the second angle value is the final angle value.
[0080] Specifically, the vehicle load sensor is set at the connection of the four wheels of the vehicle.

The tail wing motor rotates and runs different hall numbers through different angle instructions, thereby adjusting the electric tail wing with the load of the whole vehicle. Under this load compensation condition, according to the calibration, the vehicle load is set to several levels. When the setting is ≥150kg, the load compensation is started. For every increase of 100kg, a compensation adjustment parameter is updated according to the aerodynamic calibration.
[0081] When the vehicle load increases, on the one hand, the load causes the vehicle body posture to be lower, which improves the driving stability. On the other hand, the load will also increase the downforce of the vehicle on the ground and increase the vehicle adhesion. When the vehicle detects that the load size exceeds a certain value (such as more than 150kg), and the vehicle speed reaches the driving speed of each stage of the first working condition, the adjustment of the rear wing angle is corrected based on the above β0~β3.

[0082] In some embodiments, the calculation unit is further configured to perform compensation adjustment on the first angle value according to the slope information, further comprising:
[0083] Determine the slope interval where the slope of the vehicle's current position is located, and adjust the first angle value according to the slope interval and the pre-stored compensation angle value of the electric rear wing corresponding to the slope of the vehicle's current position to form a third angle value, which is the final angle value.

Under this slope compensation condition, according to the calibration, the slope of the vehicle sets a slope trigger condition. For example, when the vehicle is driving on a 5% slope, the electric tail wing starts the slope adjustment mode, and the tail wing angle is directly adjusted to β L The value can improve braking performance by increasing the downforce of the rear wing. On the other hand, the windward angle of the rear wing increases, and the air resistance generated by the rear wing itself also increases, which is conducive to reducing the vehicle speed.
