Description

Technical Field

[0001] The present application relates to the technical field of vehicle control, and particularly to a vehicle pedal control method, a vehicle pedal control system, and a vehicle. Background Art

[0002] Traditional vehicles usually adopt streamlined designs to reduce wind resistance, which to a certain extent ensures the aerodynamic performance and acceleration ability of the vehicles. However, under high-speed driving conditions, there is still room for further improvement. At present, when a vehicle is driving at high speed, the air flow leaking from both sides of the chassis will generate pressure loss, affecting the aerodynamic efficiency of the vehicle, and thus indirectly limiting its acceleration performance.

[0003] Related technologies usually adopt spoilers and rear wings to help control the air flow at the top and rear of the vehicle, increase the downforce and stabilize the vehicle body. However, the designs of these components must be precise to avoid increasing unnecessary resistance. Moreover, spoilers and rear wings are exclusive accessories for some models (such as racing cars and sports cars), rather than standard accessories for ordinary household models, so they do not have universal applicability.

[0022] If the resistance is not less than a preset resistance threshold, controlling the pedal to stop moving;

[0023] Displaying prompt information related to the pedal on the vehicle's on-board electronic terminal, and / or activating a buzzer alarm.

[0024] In some of these embodiments, LEDs are provided in the pedal; the method further includes:

[0045] The method embodiments provided in this embodiment can be executed in an in-vehicle electronic terminal, a vehicle control unit, a domain control system or a similar computing device. For example, it runs on the domain control system of a vehicle. Figure 1 It is a hardware structure block diagram of the domain control system according to an embodiment of this application. As Figure 1 shown, the domain control system may include one or more ( Figure 1 only one is shown in the figure) processors 101 and a memory 102 for storing data. Among them, the processor 101 may include, but is not limited to, a processing device such as a microprocessor MCU or a programmable logic device FPGA. The above domain control system may further include a transmission device 103 for communication functions and an input / output device 104. Those of ordinary skill in the art can understand that Figure 1 the structure shown is only schematic and does not limit the structure of the above domain control system. For example, the domain control system may further include more or fewer components than those Figure 1 shown in the figure, or have a different configuration from that Figure 1 shown.

[0046] The memory 102 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the vehicle pedal control method in this embodiment.

In one instance, the transmission device 103 includes a network adapter (Network Interface Controller, abbreviated as NIC), which can be connected to other network devices through a base station and thus can communicate with the Internet. In one instance, the transmission device 103 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0048] In one embodiment, as Figure 2 shown, a vehicle pedal control method is provided. This method is applied to a vehicle equipped with an electric pedal. The vehicle is configured with a first pedal braking mode and a second pedal braking mode. Among them, in the first pedal braking mode, the pedal is at least partially unfolded (partially or fully unfolded), and in the second pedal braking mode, the pedal retracts. Taking the method applied to the Figure 1 domain control system in this example as an illustration, it includes the following steps:

[0049] Step S101, when the vehicle is in a driving state, detect the vehicle speed.

[0050] The pedal refers to the step-on pedal for getting in and out of the vehicle installed in the vehicle.

[0051] Optionally, the driving state of the vehicle can be determined by reading the vehicle speed signal in the vehicle chassis domain. When it is confirmed that the vehicle is in a driving state, the real-time vehicle speed information can be obtained through the vehicle-built vehicle speed sensor (such as a wheel speed sensor or a GPS module).

[0052] Optionally, both the first pedal braking mode and the second pedal braking mode belong to the automatic pedal mode, that is, the vehicle is allowed to automatically control the pedal state according to the vehicle speed. In some scenarios, it is only allowed to enter the first pedal braking mode or the second pedal braking mode on the premise that the vehicle starts the automatic pedal mode. Specifically, the vehicle can be controlled to start the automatic pedal mode through the pedal controller of the vehicle.

[0053] Step S102, determine whether the vehicle speed is greater than the first threshold.

[0054] The first threshold can be the speed limit value of the highway section (such as the maximum driving speed or the minimum driving speed) or take other values. If it is determined that the vehicle speed is greater than the first threshold, it means that the vehicle is in a high-speed driving state. Optionally, if the vehicle speed is greater than the first threshold, a boolean variable can be marked as true, indicating that the switching condition is met; otherwise, it remains false. To avoid continuous comparison operations, if there is no new speed change within a certain period of time, a short sleep cycle can be set to save computing resources.

[0055] Step S103, in the case where it is determined that the vehicle speed is greater than the first threshold, switch the vehicle from the second pedal braking mode to the first pedal braking mode, or keep the vehicle in the first pedal braking mode.

[0056] When the boolean variable in step S102 is marked as true, start preparing the switching instruction and send the switching instruction to the pedal controller. If the current pedal mode is the second pedal braking mode, make it switch from the second pedal braking mode to the first pedal braking mode. If the current pedal mode is the first pedal braking mode, continue to maintain the first pedal braking mode.

[0057] Optionally, before actually performing the switch, quickly check the current vehicle state again to ensure that there are no other safety factors preventing the mode switch (such as an emergency braking situation). In addition, the driver can be informed that the pedal braking mode has been switched through the indicator light on the dashboard, sound prompt or other means, and the user can understand the current vehicle state.

[0058] Optionally, when the pedal mode of the vehicle is in the first pedal braking mode, control the pedal to at least partially unfold, and the proportion of the actual unfolding amount to the total unfolding amount is not less than the preset proportion. Such a setting can achieve the maximum benefit. The unfolding amount can refer to the pedal unfolding stroke or the pedal unfolding area. The pedal unfolding stroke refers to the distance that the pedal moves outward from the retracted position on the side of the vehicle body, and the pedal unfolding area refers to the area exposed outside the vehicle body after the pedal moves outward from the retracted position on the side of the vehicle body. In some embodiments, the value range of the first threshold is 80 km / h to 100 km / h, and the value range of the preset proportion is 50% to 60%.

[0059] In the above steps S101 to S103, based on the automatic deployment / retraction of the pedal achieved by electric control, a first pedal braking mode is added. By detecting the vehicle speed, it is determined whether the vehicle is in a high-speed driving state. If it is determined that the vehicle is in a high-speed driving state, the pedal is deployed for part or all of its travel to suppress the airflow from the chassis from flowing out from both sides, reduce the pressure loss from the middle to both sides, improve the acceleration performance of the vehicle without adding extra complex hardware, ultimately reduce the energy consumption of the vehicle during driving, and at the same time enrich the pedal function.

[0060] The benefits of the first pedal braking mode can be verified through wind tunnel tests. Wind tunnel test: An aerodynamic experimental method in which an aircraft or other object model is placed in a wind tunnel to study the gas flow and its interaction with the model to understand the aerodynamic characteristics of the actual aircraft or other object. In this embodiment, the aerodynamic differences between the deployed and retracted states of the vehicle pedal in the driving scenario can be compared to find the benefit target, that is, at what vehicle speed the pedal should be deployed to suppress the airflow from the chassis from flowing out from both sides and reduce the pressure loss from the middle to both sides, thereby improving the hundred-meter acceleration. Among them, the aerodynamic factors include drag, lift, flow separation, and downforce.

[0061] Taking a mid-large SUV model as an example for experimental testing, when the vehicle is driving, the overall drag coefficient is 0.278, and deploying the pedal can reduce the drag coefficient by 0.0046. Specifically, when the vehicle speed of the whole vehicle exceeds 100 km / h, deploying the pedal will achieve the above benefits; further, when the pedal deployment ratio is 56% (for example, the total pedal deployment amount is 142 mm and the actual deployment amount is 80 mm), the benefits reach the maximum. When the vehicle speed of the whole vehicle decreases, the benefits obtained by deploying the pedal also decrease. When the vehicle speed of the whole vehicle is less than 80 km / h, the benefits obtained by deploying the pedal disappear, and even negative benefits are generated, that is, increasing the wind resistance and wasting the vehicle's energy consumption.

[0062] In one embodiment, after determining that the vehicle speed is greater than the first threshold and switching the vehicle to the first pedal braking mode, it can be maintained for a period of time. And after maintaining for a period of time, continue to detect the vehicle speed and compare the vehicle speed with a preset threshold. The comparison results can be divided into the following two cases:

[0063] Case 1: When it is determined that the vehicle speed is greater than or equal to the second threshold, keep the vehicle in the first pedal braking mode; where the second threshold is less than the first threshold.

[0064] During vehicle driving and when the vehicle is in the first pedal braking mode, it is possible for the vehicle speed to increase to be greater than the first threshold, and this situation continues to keep the vehicle in the first pedal braking mode. Additionally, it is also possible that the vehicle appropriately reduces its speed in order to avoid or turn, and then continues to increase its speed. This situation only involves a brief deceleration with a slight reduction in vehicle speed. At this time, the deployment of the pedal will still yield positive benefits. Therefore, this situation will also continue to keep the vehicle in the first pedal braking mode, which is also conducive to ensuring the driving stability of the vehicle.

[0065] Situation 2: When it is determined that the vehicle speed is greater than or equal to the third threshold and less than the second threshold, switch the vehicle to the second pedal braking mode; where the third threshold is greater than or equal to zero and less than the second threshold.

[0066] During vehicle driving and when the vehicle is in the first pedal braking mode, it is possible that the vehicle has passed a highway section or there is a traffic jam ahead, and the vehicle needs to decelerate. When it is detected that the vehicle speed drops below the second threshold (and greater than or equal to the third threshold), it means that the benefits obtained from the deployment of the pedal disappear or even generate negative benefits at this time, and the pedal needs to be retracted.

[0067] It should be noted that in this embodiment, when the vehicle is in a driving state and in the second pedal braking mode, the prerequisite for triggering the first pedal braking mode is that the vehicle speed reaches above the first threshold (including the first threshold). If the vehicle speed does not reach above the first threshold, the first pedal braking mode will not be triggered. After the first pedal braking mode is triggered when the vehicle speed reaches above the first threshold, the subsequent vehicle speed decision-making will be processed according to the above situations.

[0068] For ease of understanding, a specific example of a mid - large SUV model is provided in an embodiment. For a mid - large SUV model, the first threshold can be taken as 100 km / h, the second threshold can be taken as 80 km / h, and the third threshold can be taken as 5 km / h. In practical applications, when the user starts the vehicle and the vehicle speed begins to increase, when the vehicle speed exceeds 5 km / h, the pedal is retracted, the pedal controller is turned off, and the second preset time is maintained. When the vehicle speed increases to above 100 km / h, the pedal controller is turned on, and the pedal mode is switched to the first pedal braking mode. At this time, the pedal is fully or partially deployed and maintained for a period of time. Next, the vehicle speed is continuously detected, and it is divided into the following situations:

[0069] When the vehicle speed increases based on the previously detected value, the vehicle continues to maintain the first pedal braking mode. Or, when the vehicle speed starts to decrease based on the previously detected value but does not drop below 80 km / h, the vehicle continues to maintain the first pedal braking mode. Or, when the vehicle speed starts to decrease based on the previously detected value and drops to 80 km / h (and is greater than or equal to 5 km / h), it switches to the second pedal braking mode and maintains it for a period of time. Then, continue a new round of vehicle speed detection, and so on, to control the pedal according to the vehicle speed, thereby minimizing vehicle energy consumption as much as possible.

[0070] In one embodiment, after determining that the vehicle speed is greater than the first threshold and switching the vehicle to the first pedal braking mode, the method further includes:

[0071] Recording the number of times the pedal is deployed and / or retracted; if the number of times is greater than the preset number within the first preset time, switch the vehicle to the second pedal braking mode and maintain the second pedal braking mode for the second preset time.

[0072] In this embodiment, if the pedal is frequently deployed and / or retracted within the first preset time, it is easy to cause physical wear to the pedal and other related components. Therefore, the vehicle can be directly switched to the second pedal braking mode and maintained for the second preset time. That is, within the second preset time, the braking mode of the pedal no longer responds to the change in vehicle speed, thereby avoiding excessive physical wear of the pedal and related components.

[0073] In one embodiment, the vehicle is further configured with a third pedal braking mode and / or a fourth pedal braking mode. Among them, the third pedal braking mode is triggered when the vehicle speed is zero; in the third pedal braking mode: when the vehicle is unlocked, the pedal is deployed; when the vehicle is locked, the pedal is retracted. For example, when the user unlocks the vehicle, the pedals on both sides automatically deploy. When the user leaves the vehicle and locks the vehicle, the pedals on both sides automatically retract. Such a setting facilitates the user to get on and off the vehicle and improves the user experience.

[0074] In the fourth pedal braking mode, the pedal is retracted and deployment is prohibited. When the vehicle activates the suspension lowering function or the jack mode, the fourth pedal mode is triggered, and a prompt message related to the pedal is displayed on the vehicle's on-board electronic terminal.

[0075] For example, when the vehicle activates the suspension lowering function to facilitate passing through some special sections (such as tunnels and bridge openings), the pedal needs to be retracted, and even when the vehicle speed is greater than the first threshold, the pedal cannot be deployed. At this time, the fourth pedal braking mode is triggered, and the in-vehicle electronic terminal reminds the user that the vehicle has been lowered and the pedal will be disabled to ensure that the vehicle reaches the specified minimum ground clearance. Taking a mid - to - large - sized SUV model as an example, the shortest vertical distance between the bottom of the vehicle front end and the ground is 170 mm, and the shortest vertical distance between the bottom of the vehicle rear end and the ground is 184 mm. Optionally, the pedal can be disabled by turning off the pedal controller.

[0076] In one embodiment, the pedal is provided with an LED. When the pedal is deployed, the LED lights up; and / or when the pedal is retracted, the LED goes out. The LED light changes accordingly with the movement process of the pedal, providing necessary lighting not only in low - brightness environments but also increasing the aesthetics and further enhancing the user experience.

[0077] In one embodiment, the method further includes: detecting the resistance during the movement process of the pedal when it is deployed or retracted; if the resistance is not less than the preset resistance threshold, controlling the pedal to stop moving; displaying prompt information related to the pedal on the in - vehicle electronic terminal of the vehicle, and / or activating the buzzer alarm. For example, when the pedal is in the movement process, that is, during the deployment or retraction of the pedal, if the detected resistance ≥ 150 N, the pedal is controlled to stop moving. At this time, the in - vehicle electronic terminal pops up a window to prompt the user, or activates the buzzer alarm, achieving the effect of anti - pinch and anti - collision.

[0078] In some embodiments, the above - mentioned method further includes: when the pedal fails, the in - vehicle electronic terminal pops up a window to prompt the user. When the user uses the off - road mode and activates the automatic pedal function, the in - vehicle electronic terminal reminds the user to be careful of ground obstacles to avoid damaging the electric pedal. When a vehicle collision accident occurs, the automatic pedal function will be disabled. Optionally, the pedal can be disabled by turning off the pedal controller.

[0079] It should be understood that although the steps in the flowcharts involved in the above - mentioned embodiments are displayed in sequence according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless there is a clear description in this article, the execution of these steps has no strict order limit, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above - mentioned embodiments may include multiple steps or multiple stages. These steps or stages are not necessarily executed at the same moment, but can be executed at different moments. The execution order of these steps or stages is not necessarily sequential, but can be executed alternately or in turn with at least a part of other steps or steps or stages in other steps.

[0080] In one embodiment, Figure 3 Another vehicle pedal control method is provided.

[0081] As Figure 3 shown, the process includes the following steps:

[0082] Step S201, the vehicle starts and travels.

[0083] Step S202, detect the vehicle speed.

[0084] Step S203, determine whether the vehicle speed is greater than the first threshold; if so, go to step S204; if not, go to step S211; if the vehicle speed is 0, end the process.

[0085] Step S204, turn on the pedal controller.

[0086] Step S205, switch the vehicle to the first pedal braking mode and maintain for a second preset time.

[0087] Step S206, determine whether the number of pedal actions is greater than a preset number within the first preset time; if so, go to step S207; if not, go to step S208.

[0088] Step S207, switch the vehicle to the second pedal braking mode and maintain for a second preset time; after the second preset time ends, return to step S202.

[0089] Step S208, detect the vehicle speed.

[0090] Step S209, determine the vehicle speed; if the vehicle speed is greater than or equal to the second threshold, go to step S210; if the vehicle speed is greater than or equal to the third threshold and less than the second threshold, go to step S207; if the vehicle speed is 0, end the process.

[0091] Step S210, keep the vehicle in the first pedal braking mode and maintain for a second preset time; after the second preset time ends, return to step S208.

[0092] Step S211, turn off the pedal controller and maintain for a second preset time; after the second preset time ends, return to step S202.

[0093] The above steps S201 to S211 perform vehicle speed detection and judgment throughout the process of the vehicle starting and traveling to the end of traveling, and switch the pedal braking mode according to the vehicle speed to reduce energy consumption when the vehicle is traveling at high speed (vehicle speed greater than the first threshold).

[0094] In one embodiment, Figure 4 A vehicle pedal control system is provided, as Figure 4As shown in the figure, the system includes: a domain control system 100 and a pedal 200. The domain control system 100 is connected to the pedal 200. Among them, the pedal 200 includes a first pedal 201 and a second pedal 202, and the first pedal 201 and the second pedal 202 are respectively arranged on the left and right sides of the vehicle. The domain control system 100 is used to control the state of the pedal 200 by executing the vehicle pedal control method described in any one of the above. It should be noted that for the specific examples in this embodiment, reference can be made to the examples described in the above embodiment and the optional implementation manners, and details will not be repeated in this embodiment.

[0095] In one embodiment, Figure 5 a structural block diagram of a domain control system is provided, as Figure 5 shown. The domain control system 100 includes: a chassis domain 101 and a pedal controller 102. The output end of the chassis domain 100 is connected to the input end of the pedal controller 102. Among them, the chassis domain 100 is used to output a vehicle speed signal; the pedal controller 102 is used to receive the vehicle speed signal and control the pedal 200 to deploy or retract based on the vehicle speed signal.

[0096] In one embodiment, Figure 6 a structural block diagram of a domain control system is provided, as Figure 6 shown. On the basis of Figure 5 the above, the domain control system further includes: a body domain 103 and a power domain 104.

Among them, the body domain 103 is used to output a door opening / closing signal and a central locking state; the power domain 104 is used to output a P gear signal.

[0097] Optionally, the domain control system further includes a pedal switch 105. The pedal switch 105 is connected to the pedal controller 102 and is used to trigger the pedal controller 102 to be in an enabled state. When the pedal switch 105 is turned on, the pedal controller 102 is in an enabled state, and at this time, the pedal automatic mode is turned on, that is, the first pedal braking mode and the second pedal braking mode are supported. When the pedal switch 105 is turned off, the pedal controller 102 is not enabled, and the pedal automatic mode is turned off, and at this time, the pedal is disabled.

[0098] Optionally, the pedal controller 102 is built-in with a buzzer 1021. When the pedal is moving, if it detects that the resistance is large, it controls the pedal to stop moving and starts the buzzer alarm to achieve the effect of anti-pinch and anti-collision.

[0099] In one embodiment, Figure 7 a vehicle pedal control system is provided, as Figure 7 shown. On the basis of Figure 6On this basis, the vehicle pedal control system further includes: an LED module, which is arranged on the pedal. Specifically, the LED module includes a first LED light group 2011 and a second LED light group 2012. Among them, the first LED light group 2011 is arranged on the first pedal 201, and the second LED light group 2012 is arranged on the second pedal 202. When the pedal 200 is deployed, the first LED light group 2011 and the second LED light group 2012 are lit; or when the pedal 200 is retracted, the first LED light group 2011 and the second LED light group 2012 are extinguished. The LED lights change accordingly according to the movement process of the pedal, providing necessary lighting and increasing aesthetics in a low-light environment, thus enhancing the user experience.

[0100] In one embodiment, a vehicle is provided, which includes a main body and any one of the above vehicle pedal control systems, and the vehicle pedal control system is installed in the main body. The vehicle realizes automatic deployment and automatic retraction of the pedal through an electric control method. In addition, on the basis of the automatic deployment / retraction of the pedal realized by electric control, a first pedal braking mode is added. By detecting the vehicle speed, it is determined whether the vehicle is in a high-speed driving state. If it is determined that the vehicle is in a high-speed driving state, the pedal is deployed for part or all of the stroke, suppressing the airflow of the chassis from flowing out from both sides, reducing the pressure loss from the middle to both sides, improving the acceleration performance of the vehicle without adding additional complex hardware, ultimately reducing the energy consumption of the vehicle during driving, and at the same time enriching the pedal function. It should be noted that specific examples in this embodiment can refer to the examples described in the above embodiments and optional implementation manners, and will not be repeated in this embodiment.

[0101] In some of these embodiments, the vehicle pedal also has functions such as overspeed disabling, fault display, anti-pinch and anti-collision, buzzer alarm, light following, off-road mode reminder, jack mode, suspension for easy entry and exit, collision disabling, and keeping closed, enhancing the interactive experience with the user. For example, when it is detected that the current vehicle speed exceeds the road-specified vehicle speed, if the vehicle is in the first pedal braking mode at this time, it is forced to switch to the second pedal braking mode, and the pedal switch 105 is closed, that is, the pedal automatic mode is closed and the pedal is disabled. For example, when it is detected that the current vehicle speed exceeds the road-specified vehicle speed, if the vehicle is in the second pedal braking mode at this time, the pedal switch 105 is directly closed to disable the pedal.
