Method, device, equipment and medium for preventing misstep of automobile accelerator pedal and automobile
[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] The present application claims priority to the Chinese patent application No. 202411308976.5, filed on September 18, 2024, and entitled "Method, device, equipment and medium for preventing misstep of automobile accelerator pedal and automobile", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD
[0003] The present application relates to the technical field of vehicle control, in particular to a method, device, equipment and medium for preventing misstep of an automobile accelerator pedal and an automobile. BACKGROUND
[0004] Compared with traditional fuel vehicles, the power response speed of pure electric vehicles is faster. In the process of high-speed driving, once the accelerator pedal is misstepped, the severity of the accident is difficult to imagine in theory.
[0005] At present, in order to reduce the safety hazards caused by the misstep of the accelerator pedal by the driver, many methods for preventing the misstep of the accelerator pedal have been proposed. Most of the methods for preventing the misstep of the accelerator pedal are to set the accelerator pedal opening degree and the opening degree change rate threshold to determine the misstep of the accelerator pedal, and then to control the electric vehicle according to the determination result. Although these methods can reduce the safety hazards caused by the misstep of the accelerator pedal by the driver to a certain extent, the accuracy of the misstep determination of the accelerator pedal is low. Moreover, considering that different drivers have different driving behavior characteristics, the opening degree and the opening degree change rate of the accelerator pedal when some drivers step on the accelerator pedal normally are not significantly different from those when other drivers misstep the accelerator pedal. Therefore, in the control process, the influence of the driving intention of the driver for overtaking on the opening degree and the opening degree change rate of the accelerator pedal is not considered, and only the setting of the pedal threshold is easy to cause misjudgment. SUMMARY
[0006] Therefore, the present application provides a method, device, equipment and medium for preventing misstep of an automobile accelerator pedal and an automobile to solve the problem of misjudgment in preventing misstep of the automobile accelerator pedal.

[0021] In an optional embodiment, the safety distance between the automobile and the obstacle vehicle is obtained by: calculating the product of the brake signal transmission time of the automobile and the first speed to obtain a to-be-braked distance of the automobile; obtaining the friction coefficient between the automobile and the ground, and calculating the braking distance in the process of reducing the first speed to the second speed according to the first speed, the second speed and the friction coefficient; and calculating the sum of the to-be-braked distance and the braking distance to obtain the safety distance.
[0022] The application can determine the safety distance required for the vehicle to avoid collision with the obstacle vehicle under the condition of deceleration when the accident is likely to occur, thereby avoiding the occurrence of traffic accidents and improving driving safety by calculating the braking distance and the distance to be braked of the vehicle.

[0058] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.
[0059] The embodiments of the present application are suitable for the scene of detecting the accelerator pedal during the driving of the driver driving the vehicle to prevent traffic accidents caused by the misstep of the driver. The embodiments of the present application provide a misstep prevention method for the accelerator pedal of a vehicle, which achieves the effect of accurately preventing misstep by comprehensively analyzing the front obstacle vehicle driving information, the vehicle driving information and the accelerator pedal opening degree after detecting the change of the opening degree of the accelerator pedal.
[0060] According to the embodiments of the present application, a misstep prevention method for the accelerator pedal of a vehicle is provided. It should be noted that the steps shown in the flowchart of the drawings can be executed in a computer system such as a group of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that here.
[0061] In the present embodiment, a misstep prevention method for the accelerator pedal of a vehicle is provided, which can be used in the above-mentioned vehicle. FIG. 1 is a flowchart of a misstep prevention method for the accelerator pedal of a vehicle according to the embodiments of the present application. As shown in FIG. 1, the flowchart includes the following steps:
[0062] Step S101, after detecting the change of the opening degree of the accelerator pedal, judging whether there is an obstacle vehicle in front of the lane in which the vehicle is running.
[0063] Specifically, in the embodiment of the present application, during driving the car, the driver controls the opening degree of the engine throttle by the accelerator pedal, thereby controlling the power output of the engine. The driver changes the power output of the engine by changing the depth of the accelerator pedal, so that the car accelerates or decelerates. However, if the driver mistakenly steps on the accelerator pedal, a traffic accident may occur. For example, if the driver mistakenly steps on the accelerator pedal and the car suddenly accelerates, if there is a car in front of the car, a rear-end collision accident may occur. Therefore, the embodiment of the present application detects the opening degree of the accelerator pedal in real time, and if the opening degree changes, immediately determines whether there is an obstacle vehicle in front of the lane in which the car is driving (i.e. the front of the car driven by the driver) by the radar in front of the car, thereby determining whether the driver has an intention to accelerate forward, but not limited to this. If there is no obstacle vehicle in front of the car, it is determined that the driver has an intention to accelerate forward, i.e. it is determined that the accelerator pedal is not mistakenly stepped on. In this case, even if the driver does not have an intention to accelerate forward, because there is no vehicle in front of the car, the car accelerating will not cause a traffic accident, and the driver will quickly react and timely control the car after accelerating.
[0064] Step S102, if there is an obstacle vehicle, obtaining driving information of the car, and predicting whether the user performs lane changing and overtaking according to the driving information.
[0065] Specifically, in the embodiment of the present application, although it is detected that there is an obstacle vehicle in front of the car driven by the driver, it cannot be determined that the driver does not have an intention to accelerate forward, because in the scenario that there is an obstacle vehicle in front of the car, it is possible that the driver pre-controls the car to change lanes and overtake, so it is necessary to determine whether the driver has an intention to change lanes and overtake. The embodiment of the present application obtains driving information of the car such as driving state information and driving environment information of the car by the terminal sensors such as radar sensors, steering wheel sensors, speed sensors and the like, thereby determining whether the driver has an intention to change lanes and overtake and the conditions of changing lanes and overtaking according to the driving information, and predicting whether the user performs lane changing and overtaking. If the driver really wants to perform lane changing and overtaking, it is determined that the driver has an intention to accelerate forward, i.e. it is determined that the accelerator pedal is not mistakenly stepped on, and the driver controls the car to accelerate and turn to realize lane changing and overtaking.
[0066] Step S103, if lane changing and overtaking is not performed, determining whether the accelerator pedal is mistakenly stepped on according to the relative driving state of the car and the obstacle vehicle and the opening degree information of the accelerator pedal.
[0067] Specifically, in the embodiment of the present application, although it is determined that there is an obstacle vehicle in front of the vehicle driven by the driver and the driver does not perform lane changing and overtaking, it cannot be determined that the driver does not have the intention of forward acceleration because the obstacle vehicle in front is possibly far away and the driver is likely to pre-control the vehicle for forward acceleration, so it is needed to determine whether there is a forward acceleration condition at this time. The embodiment of the present application acquires the relative driving state between the vehicle driven by the driver and the obstacle vehicle, including the relative speed and the relative distance, through the radar sensor attached to the vehicle, and determines whether there is a forward acceleration condition based on the opening information of the accelerator pedal, which is equivalent to determining whether a rear-end collision accident will occur if the forward acceleration is performed. If there is no forward acceleration condition at this time, it is determined that the accelerator pedal is mistakenly stepped on; if there is a forward acceleration condition at this time, it is determined that the accelerator pedal is not mistakenly stepped on.
[0068] In step S104, if it is determined that the accelerator pedal is not mistakenly stepped on, power output is performed according to the throttle opening corresponding to the accelerator pedal, and if it is determined that the accelerator pedal is mistakenly stepped on, the power output is controlled so that the vehicle maintains the speed and the throttle opening is set to a preset opening value.
[0069] Specifically, in the embodiment of the present application, if it is determined that the accelerator pedal is not mistakenly stepped on through the above-mentioned various condition analysis, corresponding power output is performed according to the throttle opening corresponding to the accelerator pedal, the vehicle accelerates and drives, and the anti-mistaken-stepping detection continues after the power output is performed. However, if it is determined that the accelerator pedal is mistakenly stepped on, in order to avoid the occurrence of traffic accidents, the power output of the engine is controlled so that the vehicle maintains the existing speed, and the throttle opening is set to 0%, but it is not limited to this, and the anti-mistaken-stepping detection is re-performed after detecting that the opening of the accelerator pedal changes again.
[0070] The anti-mistaken-stepping method for the accelerator pedal of the vehicle provided in the embodiment of the present application determines whether there is an obstacle vehicle in front of the lane in which the vehicle drives after detecting that the opening of the accelerator pedal changes, and if there is, it predicts whether the user performs lane changing and overtaking according to the driving information of the vehicle, and if not, it determines whether the accelerator pedal is mistakenly stepped on according to the relative driving state of the vehicle and the obstacle vehicle and the opening information of the accelerator pedal, and if not, it performs power output, and if so, it controls the power output. The present application can predict the driving intention of the driver according to the driving related information by performing multi-parameter comprehensive judgment after the accelerator pedal is stepped on, so as to accurately determine whether the accelerator pedal is mistakenly stepped on based on the driving intention, avoid limiting the accelerator pedal when it is not mistakenly stepped on, and ensure driving safety in time when it is mistakenly stepped on. Moreover, the collected parameters and judgment conditions can be obtained through the existing sensors on the vehicle, without the need for additional equipment, less modification of the vehicle, and no additional cost.
[0071] A method for preventing missteps of an accelerator pedal of a vehicle is provided in the embodiment, which can be applied to the vehicle described above. FIG. 2 is a flowchart of the method for preventing missteps of the accelerator pedal of the vehicle according to the embodiment of the application. As shown in FIG. 2, the flowchart includes the following steps.
[0072] In step S201, it is judged whether there is an obstacle vehicle in front of the lane in which the vehicle travels after detecting that the opening degree of the accelerator pedal changes. For details, refer to step S101 of the embodiment shown in FIG. 1, which will not be described here again.
[0073] In step S202, if there is an obstacle vehicle, the driving information of the vehicle is acquired, and it is predicted whether the user performs lane changing and overtaking according to the driving information.
[0074] Specifically, step S202 includes the following steps.
[0075] In step S2021, the driving state information of the vehicle is acquired, and it is judged whether the user has the intention of lane changing and overtaking according to the driving state information.
[0076] Specifically, in the embodiment of the application, it is considered that the driver turns on the turn signal of the corresponding direction, turns the steering wheel to the corresponding direction, and increases the stepping force of the accelerator pedal to accelerate and overtake when performing lane changing and overtaking, for example, the left turn signal is turned on, the steering wheel is turned to the left, which are only examples and are not limited thereto. Therefore, the steering wheel sensor arranged on the vehicle is used to collect the turning angle of the steering wheel, the use of the current turn signal is acquired by the area controller, and the current speed standard deviation of the vehicle is collected by the speed sensor, so as to judge whether the user has the intention of lane changing and overtaking according to the turning angle of the steering wheel, the use of the turn signal and the current speed. Specifically, the speed standard deviation is greater than 6 km / h, but is not limited thereto.
[0077] In step S2022, if the user has the intention of lane changing and overtaking, the overtaking direction is determined according to the driving state information.
[0078] Specifically, in the embodiment of the application, if it is determined that the driver has the intention of lane changing and overtaking, the overtaking direction of the intention of the driver is further determined according to the driving state information, for example, if the left turn signal is turned on and the steering wheel is turned to the left, it is determined that the overtaking direction is the left side, which is only an example and is not limited thereto.
[0079] In step S2023, the driving environment information of the vehicle is acquired according to the overtaking direction, and it is judged whether there is the condition of lane changing and overtaking according to the driving environment information.
[0080] Specifically, in the embodiment of the present application, the driving environment information of the overtaking direction of the vehicle is collected by radar, and whether there is an obstacle, such as a vehicle, a fence, etc., on the overtaking side is detected, which is only an example and is not limited thereto. At the same time, it is determined whether there is a lane-changing and overtaking condition if the lane-changing is performed at this time according to the driving environment information. If there is an obstacle on the overtaking side, there is no lane-changing and overtaking condition, that is, if the lane-changing is performed, a traffic accident is likely to occur.
[0081] In step S2024, if there is a lane-changing and overtaking intention and a lane-changing and overtaking condition, it is determined that the user performs lane-changing and overtaking, and it is determined that the accelerator pedal is not mistakenly stepped, otherwise it is determined that the user does not perform lane-changing and overtaking.
[0082] Specifically, in the embodiment of the present application, as shown in FIG. 3, in order to ensure driving safety, when it is determined that the driver has a lane-changing and overtaking intention and there is a lane-changing and overtaking condition at this time, it is determined that the user wants to perform lane-changing and overtaking, and at this time, no false step detection is performed, that is, it is determined that the accelerator pedal is not mistakenly stepped. However, if at least one of the lane-changing and overtaking intention or the lane-changing and overtaking condition is not present, it is determined that the driver does not perform lane-changing and overtaking at this time, and the next false step detection is continued.
[0083] In step S203, if lane-changing and overtaking is not performed, it is determined whether the accelerator pedal is mistakenly stepped according to the relative driving state of the vehicle and the obstacle vehicle and the opening information of the accelerator pedal.
[0084] Specifically, the above step S203 includes:
[0085] In step S2031, the first speed of the vehicle and the second speed of the obstacle vehicle are obtained.
[0086] Specifically, in the embodiment of the present application, as shown in FIG. 3, the first speed v1 of the vehicle driven by the driver is obtained by a speed sensor, and the second speed v2 of the front obstacle vehicle is obtained by radar, and the relative speed information between the two vehicles can be determined.
[0087] In step S2032, if the first speed is greater than or equal to the second speed, the distance interval and the safety distance between the vehicle and the obstacle vehicle are obtained.
[0088] Specifically, in the embodiment of the present application, as shown in FIG. 3, the relative speed information between the vehicle driven by the driver and the front obstacle vehicle is determined, and if the first speed v1 is greater than or equal to the second speed v2, it is proved that the distance between the two vehicles is gradually approaching at this time. At this time, the distance interval ΔS between the vehicle driven by the driver and the obstacle vehicle is obtained by radar, and the safety distance of the vehicle is calculated according to the first speed v1 of the vehicle driven by the driver, and the false step detection is further performed according to the relative distance information.
[0089] In some optional embodiments, the embodiments of the present application calculate the safety distance according to the braking function of the automobile, and the specific calculation process is as shown below:
[0090] (1) Calculate the product of the braking signal transmission time t1 of the automobile and the first speed v1 to obtain the to-be-braked distance S1 of the automobile, and the calculation formula is as shown below: S1=v1*t1
[0091] Wherein, the braking signal transmission time t1 is the time for transmitting the braking signal to the motor and the braking system, and the motor and the braking system start to take effect, which is generally 0.02-0.05s, s is second.
[0092] (2) Obtain the friction coefficient μ of the automobile and the ground, and calculate the braking distance S2 in the process of reducing the first speed v1 to the second speed v2 according to the first speed v1, the second speed v2 and the friction coefficient μ, and the calculation formula is as shown below: S2=(v1 2 -v2 2 ) / 2a=(v1 2 -v2 2 ) / 2μg
[0093] Wherein, the deceleration is a=μg, μ is the friction coefficient of the automobile and the ground, and the value is 0.7; g is the gravity coefficient, and g=9.8m / s 2 , s is second.
[0094] (3) Calculate the sum of the to-be-braked distance S1 and the braking distance S2 to obtain the safety distance S, and the calculation formula is as shown below: S=S1+S2
[0095] Step S2033, if the distance interval is greater than the safety distance, the opening of the accelerator pedal and the opening change rate are obtained.
[0096] Specifically, in the embodiments of the present application, as shown in FIG. 3, if the distance interval ΔS between the two automobiles at this time is greater than the safety distance S, the opening of the accelerator pedal and the opening change rate are obtained through the accelerator pedal sensor, and the false step detection is continued.
[0097] Step S2034, if the opening or the opening change rate is greater than or equal to the corresponding preset threshold, it is determined that the accelerator pedal is false stepped.
[0098] Specifically, in the embodiment of the present application, if the opening degree of the accelerator pedal or the opening degree change rate is greater than the corresponding preset threshold, it is determined that the accelerator pedal is mispressed, otherwise, it is determined that the accelerator pedal is not mispressed. Specifically, the preset threshold of the opening degree of the accelerator pedal can be, but is not limited to, 50%, and the preset threshold of the opening degree change rate of the accelerator pedal can be, but is not limited to, 40% within 50 ms. If the opening degree is not less than 50% and the opening degree change rate is not less than 40% within 50 ms, it is determined that the accelerator pedal is mispressed, and the vehicle is controlled to keep the original speed. If the opening degree is less than 50% and the opening degree change rate is less than 40% within 50 ms, it is determined that the accelerator pedal is not mispressed, which is only an example and is not limited thereto.
[0099] In some optional embodiments, the embodiment of the present application sets the accelerator pedal opening degree threshold and the opening degree change rate threshold by testing the speed of multiple drivers during normal driving and overtaking driving, and taking the maximum opening degree and the opening degree change rate of the accelerator pedal during overtaking driving as preset conditions. The test results are divided into different stages based on 50 ms, and the maximum opening degree change value of the accelerator pedal in different stages is calculated. Through data analysis, it is known that the maximum opening degree value of the accelerator pedal within 50 ms during normal driving is distributed in 10% to 20%, and the maximum opening degree value of the accelerator pedal during fast overtaking is distributed in 20% to 50%. Therefore, the accelerator pedal opening degree threshold is set to 50%, and the opening degree change rate threshold is set to 40% within 50 ms.
[0100] If it is determined that the accelerator pedal is not mispressed, the power output is performed according to the corresponding throttle opening degree of the accelerator pedal, and if it is determined that the accelerator pedal is mispressed, the power output is controlled to keep the speed of the vehicle unchanged, and the throttle opening degree is set to a preset opening degree value. For details, please refer to step S104 of the embodiment shown in FIG. 1, which will not be described here.
[0101] The method for preventing mispressing of the accelerator pedal of the vehicle provided by the embodiment of the present application can determine whether the accelerator pedal is mispressed by judging whether there is an obstacle vehicle in front of the lane in which the vehicle travels after detecting that the opening degree of the accelerator pedal changes, predicting whether the user performs lane changing and overtaking according to the driving information of the vehicle if there is an obstacle vehicle, judging whether the accelerator pedal is mispressed according to the relative driving state of the vehicle and the obstacle vehicle and the opening degree information of the accelerator pedal if the user does not perform lane changing and overtaking, performing power output if the accelerator pedal is not mispressed, and performing power output control if the accelerator pedal is mispressed. The present application can predict the driving intention of the driver according to the driving related information by comprehensively judging multiple parameters after the accelerator pedal is pressed down, so as to accurately determine whether the accelerator pedal is mispressed based on the driving intention, avoid limiting the accelerator pedal when it is not mispressed, and ensure driving safety in time when it is mispressed.
[0102] A method for preventing false stepping of an accelerator pedal of a vehicle is provided in the embodiment, which can be applied to the vehicle described above. FIG. 4 is a flowchart of the method for preventing false stepping of the accelerator pedal of the vehicle according to the embodiment of the application. As shown in FIG. 4, the flowchart includes the following steps:
[0103] In step S401, it is determined whether there is an obstacle vehicle in front of the lane in which the vehicle travels after detecting a change in the opening degree of the accelerator pedal. For details, please refer to step S201 of the embodiment shown in FIG. 2, which will not be described here again.
[0104] In step S402, if there is an obstacle vehicle, the driving information of the vehicle is obtained, and it is predicted whether the user performs lane changing and overtaking according to the driving information. For details, please refer to step S202 of the embodiment shown in FIG. 2, which will not be described here again.
[0105] In step S403, if lane changing and overtaking is not performed, it is determined whether the accelerator pedal is false stepped according to the relative driving state of the vehicle and the obstacle vehicle and the opening degree information of the accelerator pedal.
[0106] Specifically, step S403 includes the following steps:
[0107] In step S4031, if the first speed is less than the second speed, it is determined that the accelerator pedal is not false stepped.
[0108] Specifically, in the embodiment of the application, as shown in FIG. 3, if it is determined that the first speed v1 of the vehicle driven by the driver is less than the second speed v2 according to the relative speed information between the vehicle driven by the driver and the obstacle vehicle in front, it is proved that the driver has an intention of forward acceleration at this time, and it is determined that the accelerator pedal is not false stepped, and no false stepping prevention detection is performed.
[0109] In step S4032, if the first speed is greater than or equal to the second speed, and the distance interval is less than or equal to the safety distance, the power output is reduced until the first speed is less than or equal to the second speed.
[0110] Specifically, in the embodiment of the application, if the first speed v1 is greater than or equal to the second speed v2, it is proved that the driver does not have an intention of forward acceleration at this time, but the speed of the vehicle is relatively fast, and it is necessary to determine whether the vehicle driven at the first speed v1 at this time is likely to have a traffic accident with the obstacle vehicle in front. The embodiment of the application determines whether the relative distance interval ΔS between the two vehicles is less than the safety distance S. If it is less than the safety distance S, it is proved that the distance traveled by the vehicle after the speed is reduced to the second speed v2 without inhibiting the power output is greater than the distance interval ΔS, and therefore the two vehicles are likely to collide. Therefore, the vehicle controller controls the braking system of the vehicle to directly generate the maximum braking force to brake, reduces the power output, and actively slows down, so as to complete the process of emergency braking as soon as possible until the first speed v1 is less than or equal to the second speed v2, thereby ensuring driving safety.
[0111] In step S4033, if the first speed is greater than or equal to the second speed, the distance interval is greater than the safety distance, and the opening or the opening change rate is less than the corresponding preset threshold, it is determined that the accelerator pedal is not mistakenly stepped on.
[0112] Specifically, in the embodiment of the present application, if the first speed v1 is greater than or equal to the second speed v2, it is proved that the driver does not have the forward acceleration intention at this time, and the distance interval ΔS is greater than the safety distance S at this time, and there is no collision risk. At the same time, the change of the accelerator pedal is consistent with the driving operation of the driver, so it is determined that the accelerator pedal is not mistakenly stepped on.
[0113] In step S404, if it is determined that the accelerator pedal is not mistakenly stepped on, the power output is performed according to the throttle opening corresponding to the accelerator pedal, and if it is determined that the accelerator pedal is mistakenly stepped on, the power output is controlled to keep the speed of the vehicle unchanged, and the throttle opening is set to a preset opening value. For details, please refer to step S204 of the embodiment shown in FIG. 2, which will not be repeated here.
[0114] The method for preventing the accelerator pedal of the vehicle from being mistakenly stepped on provided in the embodiment of the present application, by detecting whether there is an obstacle vehicle in front of the lane in which the vehicle is running after detecting that the opening of the accelerator pedal changes, if there is an obstacle vehicle, predicting whether the user performs lane changing and overtaking according to the driving information of the vehicle, if not, judging whether the accelerator pedal is mistakenly stepped on according to the relative driving state of the vehicle and the obstacle vehicle and the opening information of the accelerator pedal, if not, performing power output, and if yes, controlling the power output. The present application can predict the driving intention of the driver according to the driving related information by comprehensively judging multiple parameters after the accelerator pedal is stepped on, so as to accurately judge whether the accelerator pedal is mistakenly stepped on based on the driving intention, avoid limiting the accelerator pedal when it is not mistakenly stepped on, and ensure driving safety in time when it is mistakenly stepped on.
