Description

Technical Field

[0001] This invention relates to the field of automotive active safety technology, and more specifically, to a vehicle anti-accelerator pedal control method and system based on scene perception. Background Technology

[0002] In today's era of widespread car ownership, traffic accidents caused by drivers accidentally pressing the accelerator are frequent, especially during low-speed driving, parking, or complex road conditions. Sudden acceleration due to operational errors can easily lead to personal injury and property damage. Traditional vehicle safety control systems often rely on single parameters, such as triggering protection solely based on accelerator pedal opening or vehicle speed, lacking a comprehensive understanding of the actual driving scenario and making it difficult to accurately distinguish between normal acceleration and accidental acceleration. Existing anti-accelerator-pressing technologies have significant limitations: some systems only activate protection in specific scenarios (such as reversing), resulting in a narrow scope of application; others fail to incorporate information such as vehicle position, surrounding obstacles, and road structure, leading to misjudgments or omissions, impacting both the driving experience and failing to effectively guarantee driving safety. With the development of intelligent sensing and scene perception technologies, there is an urgent need for an anti-accelerator-pressing control solution that can integrate multi-dimensional information, accurately identify driving scenarios, and dynamically adjust protection strategies to cope with complex and changing driving environments and improve vehicle driving safety and intelligence. Summary of the Invention

[0003] In view of this, the present invention addresses the shortcomings of the prior art by proposing a vehicle anti-accelerator pedal control method and system based on scene perception, aiming to solve at least one of the problems mentioned in the background art.

[0004] This invention provides a scene-aware vehicle accelerator pedal prevention control method, comprising the following steps: Acquire the target vehicle's current speed information, the target vehicle's current location information, and the target vehicle's current radar information and image information; The current driving state of the target vehicle is obtained based on its current driving speed, and the current driving state of the target vehicle is corrected based on its current location information to obtain the final driving state of the target vehicle. Based on the current radar and image information of the target vehicle, determine whether the target vehicle is in an accelerable state. When the target vehicle is in an accelerable state, determine the accelerable time threshold of the target vehicle. When the acceleration time of the target vehicle is greater than the accelerable time threshold of the target vehicle, control the target vehicle to decelerate. When the target vehicle is decelerated, a warning signal is issued.

[0005] In some embodiments, the step of obtaining the current driving state of the target vehicle based on its current speed, and correcting the current driving state of the target vehicle based on its current location information, current radar information, and image information to obtain the final driving state of the target vehicle includes: A preset speed threshold for the target vehicle's driving state is defined. When the target vehicle's driving speed is greater than the speed threshold, the target vehicle is determined to be in a high-speed driving state. When the target vehicle's speed is less than or equal to the driving speed threshold, the target vehicle is determined to be in a low-speed driving state.

[0006] In some embodiments, when obtaining the current driving state of the target vehicle based on its current driving speed, and correcting the current driving state of the target vehicle based on its current location information to obtain the final driving state of the target vehicle, the method further includes: When the target vehicle is traveling at low speed and the current location information of the target vehicle shows that the target vehicle is on the road, the target vehicle is determined to be in the first driving state. When the target vehicle is traveling at low speed and the current location information of the target vehicle shows that the target vehicle is not on the road, the target vehicle is determined to be in the second driving state.

[0007] In some embodiments, the step of determining whether the target vehicle is in an accelerable state based on the current radar information and image information of the target vehicle, determining the accelerable time threshold of the target vehicle when the target vehicle is in an accelerable state, and controlling the target vehicle to decelerate when the acceleration time of the target vehicle is greater than the accelerable time threshold of the target vehicle includes: When the target vehicle is in the first driving state, the first driving distance between the target vehicle and the vehicle in front is obtained according to the current radar information of the target vehicle. When the first driving distance is greater than a preset safe distance threshold, it is determined that the target vehicle is in an acceleration state. When the first driving distance is less than or equal to the preset safe distance threshold, the presence of vehicles to the left or right of the target vehicle is determined based on the target vehicle's current radar information. When vehicles to the left or right of the target vehicle are present, the target vehicle is determined to be in an accelerable state. When no vehicles are present to the left or right of the target vehicle, the current road conditions of the target vehicle are determined based on the target vehicle's image information.

[0008] In some embodiments, when there are no vehicles to the left or right of the target vehicle, determining the current road conditions of the target vehicle based on the image information of the target vehicle includes: Based on the image information of the target vehicle, it is determined whether the current road of the target vehicle is a multi-lane road. When the current road of the target vehicle is a multi-lane road, it is determined that the target vehicle is in an acceleration state. When the target vehicle is currently on a single-lane road, it is determined that the target vehicle is in a state where it cannot accelerate.

[0009] In some embodiments, when determining whether the target vehicle is in an accelerable state based on the current radar information and image information of the target vehicle, and when the target vehicle is in an accelerable state, determining the accelerable time threshold of the target vehicle, and when the acceleration time of the target vehicle is greater than the accelerable time threshold of the target vehicle, controlling the target vehicle to decelerate, the method further includes: When the target vehicle is in the second driving state, the current radar information of the target vehicle is used to determine whether there are obstacles around the target vehicle. When there are no obstacles around the target vehicle, it is determined that the target vehicle is in an acceleration state. When there are obstacles around the target vehicle, the target vehicle is determined to be in a state where it cannot accelerate.

[0010] In some embodiments, when determining whether the target vehicle is in an accelerable state based on the current radar information and image information of the target vehicle, and when the target vehicle is in an accelerable state, determining the accelerable time threshold of the target vehicle, and when the acceleration time of the target vehicle is greater than the accelerable time threshold of the target vehicle, controlling the target vehicle to decelerate, the method further includes: When the target vehicle is in a first driving state and the target vehicle is in an acceleration state, a first acceleration time threshold of the target vehicle is determined based on the current road speed limit value of the target vehicle. When the acceleration time of the target vehicle is greater than the first acceleration time threshold of the target vehicle, the target vehicle is controlled to decelerate.

[0011] In some embodiments, when determining whether the target vehicle is in an accelerable state based on the current radar information and image information of the target vehicle, and when the target vehicle is in an accelerable state, determining the accelerable time threshold of the target vehicle, and when the acceleration time of the target vehicle is greater than the accelerable time threshold of the target vehicle, controlling the target vehicle to decelerate, the method further includes: When the target vehicle is in the second driving state and the target vehicle is in an accelerable state, a second accelerable time threshold for the target vehicle is preset. When the acceleration time of the target vehicle is greater than the second accelerable time threshold for the target vehicle, the target vehicle is controlled to decelerate.

[0012] In some embodiments, issuing a warning signal when controlling the target vehicle to decelerate includes: When a warning signal is issued, if the accelerator pedal of the target vehicle is pressed harder than the brake pedal of the target vehicle, the deceleration control of the target vehicle is lifted.

[0013] Secondly, the present invention provides a scene-aware vehicle accelerator pedal prevention control system, comprising: The acquisition module is configured to acquire the target vehicle's current speed information, the target vehicle's current location information, and the target vehicle's current radar information and image information; The processing module is configured to obtain the current driving state of the target vehicle based on the current driving speed of the target vehicle, and correct the current driving state of the target vehicle based on the current location information of the target vehicle to obtain the final driving state of the target vehicle. The judgment module is configured to determine whether the target vehicle is in an accelerable state based on the current radar information and image information of the target vehicle. When the target vehicle is in an accelerable state, the module determines the accelerable time threshold of the target vehicle. When the acceleration time of the target vehicle is greater than the accelerable time threshold of the target vehicle, the module controls the target vehicle to decelerate. The warning module is configured to issue a warning signal when the target vehicle is controlled to decelerate.

[0014] Compared with existing technologies, the advantages of this invention are as follows: It overcomes the limitations of traditional technologies that rely on single-parameter judgment. By integrating multi-dimensional information such as vehicle speed, position, radar, and images, it achieves accurate perception of driving scenarios, effectively distinguishing between normal acceleration and accidental accelerator pedal press, significantly reducing the probability of misjudgment and missed judgment, and preventing the impact of erroneous protection on the driving experience or safety accidents caused by lack of protection. It overcomes the problem of narrow applicability of some anti-accelerator pedal press systems, covering different driving states such as low speed and high speed on roads, and also taking into account off-road scenarios. It dynamically adjusts the acceleration judgment criteria and time thresholds for different scenarios (such as multi-lane, single-lane, and whether there are obstacles nearby), providing more comprehensive protection and adapting to complex and changing driving environments. When detecting the risk of accidental pedal press and controlling the vehicle to decelerate, it simultaneously issues a warning signal while retaining the driver's emergency operation deactivation authority. This ensures driving safety while respecting the driver's control, balancing safety and operational flexibility, further improving vehicle driving safety and intelligence, and reducing personal injury and property damage caused by accidental accelerator pedal press.

[0020] See Figure 1-2 As shown, in the first embodiment, a vehicle anti-accelerator pedal control method based on scene awareness according to an embodiment of this application includes the following steps: S100: Obtain the target vehicle's current speed information, the target vehicle's current location information, and the target vehicle's current radar information and image information; S200.

S300. Determine whether the target vehicle is in an accelerable state based on the current radar information and image information of the target vehicle.

When the acceleration time of the target vehicle is greater than the accelerable time threshold of the target vehicle, control the target vehicle to decelerate. S400: When controlling the target vehicle to decelerate, issue a warning signal.

[0021] In some specific embodiments, the step of obtaining the current driving state of the target vehicle based on its current speed, and correcting the current driving state of the target vehicle based on its current location information, current radar information, and image information to obtain the final driving state of the target vehicle includes: A preset speed threshold for the target vehicle's driving state is defined. When the target vehicle's driving speed is greater than the speed threshold, the target vehicle is determined to be in a high-speed driving state. When the target vehicle's speed is less than or equal to the driving speed threshold, the target vehicle is determined to be in a low-speed driving state.

[0022] In some specific embodiments, when obtaining the current driving state of the target vehicle based on its current speed, and correcting the current driving state of the target vehicle based on its current location information to obtain the final driving state of the target vehicle, the method further includes: When the target vehicle is traveling at low speed and the current location information of the target vehicle shows that the target vehicle is on the road, the target vehicle is determined to be in the first driving state. When the target vehicle is traveling at low speed and the current location information of the target vehicle shows that the target vehicle is not on the road, the target vehicle is determined to be in the second driving state.

[0023] In some specific embodiments, the step of determining whether the target vehicle is in an accelerable state based on the current radar information and image information of the target vehicle, determining the accelerable time threshold of the target vehicle when the target vehicle is in an accelerable state, and controlling the target vehicle to decelerate when the acceleration time of the target vehicle is greater than the accelerable time threshold of the target vehicle includes: When the target vehicle is in the first driving state, the first driving distance between the target vehicle and the vehicle in front is obtained according to the current radar information of the target vehicle. When the first driving distance is greater than a preset safe distance threshold, it is determined that the target vehicle is in an acceleration state. When the first driving distance is less than or equal to the preset safe distance threshold, the presence of vehicles to the left or right of the target vehicle is determined based on the target vehicle's current radar information. When vehicles to the left or right of the target vehicle are present, the target vehicle is determined to be in an accelerable state. When no vehicles are present to the left or right of the target vehicle, the current road conditions of the target vehicle are determined based on the target vehicle's image information.

[0024] In some specific embodiments, when there are no vehicles to the left or right of the target vehicle, determining the current road conditions of the target vehicle based on the image information of the target vehicle includes: Based on the image information of the target vehicle, it is determined whether the current road of the target vehicle is a multi-lane road. When the current road of the target vehicle is a multi-lane road, it is determined that the target vehicle is in an acceleration state. When the target vehicle is currently on a single-lane road, it is determined that the target vehicle is in a state where it cannot accelerate.

[0025] It should be understood that the vehicle anti-accelerator pedal control method based on scene perception works through a three-level collaboration of "perception layer - processing layer - decision layer". The core is to accurately identify the accidental pedaling scenario and dynamically intervene by relying on multi-source data fusion. At the perception layer, the system synchronously acquires four types of key data through the acquisition module: vehicle dynamic data is collected in real time by the vehicle speed sensor with an accuracy of ±0.1km / h, while also recording the accelerator pedal opening and depressing rate, providing a basis for subsequent acceleration behavior verification; location scene data combines GPS / BeiDou positioning with high-precision maps, with positioning errors controlled within 1 meter, accurately distinguishing between "road areas" (such as urban main roads) and "non-road areas" (such as parking lots); radar environment data relies on forward millimeter-wave radar (detection distance 0-150 meters) and side ultrasonic radar (detection distance 0.2-4 meters, response time <100ms), respectively acquiring the first driving distance to the vehicle in front (accuracy ±0.3 meters), the presence of vehicles on the side, and the characteristics of surrounding obstacles; image scene data is collected by a forward-looking high-definition camera with a resolution of 1920×1080 and a frame rate of 30fps, and lane lines and road markings are extracted through image segmentation algorithms, providing visual support for determining the number of lanes.

[0026] After entering the processing layer, the system classifies the final driving state through a two-level logic of "initial classification → scenario correction": First, a driving state speed threshold of 20-30km / h is preset (referencing Nissan's EAPM system). If the vehicle speed is greater than the threshold, it is initially determined to be "low-speed driving state". If the vehicle speed is less than or equal to the threshold, it is determined to be "high-speed driving state" (in this state, the driver's intention is clear, and the anti-accidental step intervention is not activated). Then, the "low-speed driving state" is corrected based on the location information. If it is in a road area, it is determined to be "first driving state" (such as following other vehicles in urban congestion). If it is in a non-road area, it is determined to be "second driving state" (such as moving a car in a parking lot).

[0027] As the core control link, the decision-making layer designs a three-level progressive verification logic to determine the accelerability of the first driving state: The first level of verification takes the first driving distance obtained by radar as the core and compares it with the dynamically calculated preset safe distance threshold (usually 5-10 meters in low-speed scenarios, the formula is "vehicle speed × reaction time + braking distance"). If the distance is greater than the threshold, it is directly determined that the state can be accelerated; if the distance is less than or equal to the threshold, it enters the second level of verification, which scans adjacent lanes by side radar. If there are vehicles, it is determined that the state can be accelerated (the right to use the lane to overtake is retained). If there are no vehicles, it enters the third level of verification; The third level of verification is achieved through the image processing of the forward-looking camera. After the image is grayscaled and edge detected, the Hough transform algorithm is used to extract lane line features, and it is combined with high-precision map cross-verification (recognition accuracy ≥95%). If there are multiple lanes, it is determined that the state can be accelerated; if there is a single lane, it is determined that the state cannot be accelerated (acceleration at this time is likely to cause a rear-end collision, and the probability is accidental stepping).

[0028] In the acceleration-enabled state, the system also prevents continuous accidental acceleration through time threshold control: the first driving state uses a dynamic first acceleration time threshold (e.g., about 3-5 seconds at a speed limit of 40km / h, the formula is "road speed limit / acceleration"), and the second driving state uses a preset second acceleration time threshold of 2-3 seconds (refer to Nissan's EAPM system); if the acceleration time exceeds the corresponding threshold, the system immediately suppresses the throttle output through the power system (non-braking deceleration, in accordance with GB24545 standard), and at the same time, the warning module triggers a buzzer and a flashing audible and visual alarm on the instrument panel; if the throttle force is greater than the braking force after the warning, the system determines that the driver intends to accelerate actively, and will immediately release the deceleration state to ensure that the driver retains the highest control authority and avoid misjudgment interfering with normal driving.

[0029] In some specific embodiments, the step of determining whether the target vehicle is in an accelerable state based on the current radar information and image information of the target vehicle, determining the accelerable time threshold of the target vehicle when the target vehicle is in an accelerable state, and controlling the target vehicle to decelerate when the acceleration time of the target vehicle is greater than the accelerable time threshold of the target vehicle, further includes: When the target vehicle is in the second driving state, the current radar information of the target vehicle is used to determine whether there are obstacles around the target vehicle. When there are no obstacles around the target vehicle, it is determined that the target vehicle is in an acceleration state. When there are obstacles around the target vehicle, the target vehicle is determined to be in a state where it cannot accelerate.

[0030] In some specific embodiments, the step of determining whether the target vehicle is in an accelerable state based on the current radar information and image information of the target vehicle, determining the accelerable time threshold of the target vehicle when the target vehicle is in an accelerable state, and controlling the target vehicle to decelerate when the acceleration time of the target vehicle is greater than the accelerable time threshold of the target vehicle, further includes: When the target vehicle is in a first driving state and the target vehicle is in an acceleration state, a first acceleration time threshold of the target vehicle is determined based on the current road speed limit value of the target vehicle. When the acceleration time of the target vehicle is greater than the first acceleration time threshold of the target vehicle, the target vehicle is controlled to decelerate.

[0031] In some specific embodiments, the step of determining whether the target vehicle is in an accelerable state based on the current radar information and image information of the target vehicle, determining the accelerable time threshold of the target vehicle when the target vehicle is in an accelerable state, and controlling the target vehicle to decelerate when the acceleration time of the target vehicle is greater than the accelerable time threshold of the target vehicle, further includes: When the target vehicle is in the second driving state and the target vehicle is in an accelerable state, a second accelerable time threshold for the target vehicle is preset. When the acceleration time of the target vehicle is greater than the second accelerable time threshold for the target vehicle, the target vehicle is controlled to decelerate.

[0032] In some specific embodiments, issuing a warning signal when controlling the target vehicle to decelerate includes: When a warning signal is issued, if the accelerator pedal of the target vehicle is pressed harder than the brake pedal of the target vehicle, the deceleration control of the target vehicle is lifted.

[0033] A second embodiment of a scene-aware vehicle accelerator pedal prevention control system according to an embodiment of this application includes: The acquisition module is configured to acquire the target vehicle's current speed information, the target vehicle's current location information, and the target vehicle's current radar information and image information; The processing module is configured to obtain the current driving state of the target vehicle based on the current driving speed of the target vehicle, and correct the current driving state of the target vehicle based on the current location information of the target vehicle to obtain the final driving state of the target vehicle. The judgment module is configured to determine whether the target vehicle is in an accelerable state based on the current radar information and image information of the target vehicle. When the target vehicle is in an accelerable state, the module determines the accelerable time threshold of the target vehicle. When the acceleration time of the target vehicle is greater than the accelerable time threshold of the target vehicle, the module controls the target vehicle to decelerate. The warning module is configured to issue a warning signal when the target vehicle is controlled to decelerate.

[0034] It should be understood that in the scenario-aware vehicle anti-accelerator pedal control method, a complete logical chain is formed for different driving states, including acceleration determination, time threshold setting, and deceleration intervention release. When the target vehicle is in the second driving state (i.e., low speed and located in a non-road area, such as a parking lot or residential compound), the system first relies on the current radar information to determine whether there are obstacles around the vehicle. Due to the complexity of non-road environments (e.g., there may be pedestrians or other parked vehicles in a parking lot, or residents suddenly crossing in a residential compound), the forward millimeter-wave radar and the side and rear ultrasonic radars will simultaneously scan the area around the vehicle from 0.2 to 150 meters. If the radar data does not detect obstacles (e.g., an empty parking lot passage or a residential road without pedestrians), the vehicle is determined to be in an acceleration state, allowing the driver to perform normal starting or maneuvering acceleration operations. If the radar detects obstacles around the vehicle (e.g., vehicles in adjacent parking spaces or roadside bollards), it is directly determined to be in an acceleration-prohibited state, thus preventing collisions caused by accidental accelerator pedal presses from the source.

[0035] Regarding the setting of the acceleration time threshold, the system will configure it differently based on the vehicle's final driving state. When the vehicle is in the first driving state (low speed driving in a road area, such as a congested urban road or a rural road) and has been determined to be in an acceleration state, the first acceleration time threshold is not a fixed value, but is dynamically calculated based on the target vehicle's current road speed limit. For example, when the current road speed limit is 40km / h, the system will calculate the first acceleration time threshold (about 3-5 seconds) based on the vehicle's acceleration (usually referring to the vehicle's own power parameters, such as the average acceleration converted from the 0-60km / h acceleration time of a family sedan) using the formula "road speed limit / acceleration", ensuring that the acceleration behavior is always within the reasonable range allowed by the road speed limit. If the vehicle is in the second driving state and has been determined to be in an acceleration state, considering that the speed requirements in non-road scenarios are lower (usually not exceeding 20km / h), the system will preset a fixed second acceleration time threshold (usually 2-3 seconds, referring to the error correction time settings of mature systems such as Nissan EAPM), to avoid the vehicle speed exceeding the safe range of the scenario due to prolonged acceleration.

[0036] When the system determines that the acceleration time exceeds the corresponding threshold and initiates deceleration control (achieving non-braking deceleration by suppressing power system output, in compliance with GB24545 vehicle safety standards), the warning module will simultaneously issue an audible and visual warning signal (such as a continuous alarm in the vehicle and a flashing red warning light on the instrument panel). At this time, the system does not completely lock the deceleration state, but retains the driver's active control authority—if the driver continues to press the accelerator after the warning, and the pressure of the accelerator pedal exceeds the system's preset braking force threshold (this threshold is calibrated according to the vehicle's braking system parameters to ensure that it can distinguish between accidental pressing and active acceleration intent), the system will determine that the driver has a clear active acceleration need (such as overtaking in an emergency), immediately release the deceleration control of the vehicle, restore normal power output, and avoid affecting the driver's emergency operation due to system misjudgment.
