Description

Technical Field

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] With the development of vehicle networking technology and big data technology, the data recorded by vehicles is becoming increasingly rich and comprehensive.

[0004] Currently, autonomous driving relies on image recognition of road conditions, but its recognition rate for vibrations caused by uneven road surfaces is low. Sometimes, by the time the vibration is detected, the vehicle is already very close to the affected area. Existing full driver assistance systems will then apply emergency braking and swerve around the uneven surface. This approach not only causes panic for the driver but also poses a risk to driving safety. Summary of the Invention

[0030] As one implementation method, if no vibration occurs when the vehicle passes the vibration point location at a speed and tire pressure that matches the vibration model, the current vibration point location is deleted from the vibration map.

[0045] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0046] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0047] Example 1

[0048] Reference Figure 2 and Figure 3 This embodiment provides a driving safety assistance control method, which includes:

[0049] Step 1: Obtain GPS signals, driving direction information, vehicle speed signals, and tire pressure signals during vehicle operation.

[0050] Step 2: Compare the vehicle's GPS signal and driving direction information with the pre-drawn vibration map to determine if there are vibration points in the vehicle's driving direction.

[0051] When there is an oscillation point in the vehicle's direction of travel, the current vehicle speed signal and tire pressure signal are compared with the preset oscillation model to determine whether oscillation will occur after passing the corresponding oscillation point and to issue a corresponding oscillation warning.

[0052] exist Figure 4 In the system, both the oscillation map and oscillation model are stored on a cloud platform, and the audio host is used to remind the driver that oscillations may occur.

[0053] Among them, Figure 1 In the process, the tire pressure controller 5 and the vehicle speed controller 6 communicate with each other through the vehicle communication module 3 and the vehicle network backend 2 and the big data backend.

[0054] In specific implementation, the process of drawing the oscillation map is as follows:

[0055] During vehicle operation, when the vehicle stability value fluctuates beyond the set threshold range, the vehicle's GPS position at this time is recorded, and the current GPS position is used as the oscillation point.

[0056] All oscillation points are plotted on an electronic map to construct an oscillation map.

[0057] Specifically, referring to SiTime's AEC-Q100 automotive oscillator, the SOT23 oscillator stability value exceeding ±20ppm is defined as undesirable oscillation.

[0058] Referring to SiTime's AEC-Q100 automotive oscillator, the SOT23 oscillator stability value exceeding ±50ppm is defined as a dangerous oscillation.

[0059] The oscillation point was marked, and an algorithmic model was constructed based on the oscillation intensity, vehicle speed, and tire pressure. The oscillation intensity was measured using a stable value in ppm.

[0060] In practical implementation, the construction process of the oscillation model is as follows:

[0061] Each time an oscillation occurs at the same GPS location, a separate data pool is created for tire pressure and vehicle speed.

[0062] Based on the data pools of tire pressure and vehicle speed, the correlation between tire pressure and vehicle speed, as well as the correspondence between tire pressure and vehicle speed, are constructed respectively.

[0063] During vehicle operation, when the vehicle experiences oscillations with a stability value greater than ±20, the vehicle's GPS location, tire pressure, and speed are recorded. For each oscillation at the same GPS location, a separate data pool is created for tire pressure and vehicle speed. A correlation between tire pressure and vehicle speed is established, as well as a direct correlation between them. When 100 different tire pressure or vehicle speed data points are collected, 10 threshold ranges for tire pressure and vehicle speed, along with threshold binding relationships between tire pressure and vehicle speed, are established. Specifically, this defines the range of tire pressure (e.g., 230 kPa-250 kPa) and the corresponding vehicle speed (e.g., 85 km / h) at which the vehicle will experience oscillations with a stability value greater than ±20 when passing this GPS location.

[0064] Vehicle speed determination range: On the oscillation map, a model of a single point causing oscillation is constructed (during vehicle operation, when the vehicle experiences oscillations with a stable value greater than ±20, the vehicle's GPS position, tire pressure, and speed are recorded. For each oscillation at the same GPS location, a separate data pool is created for tire pressure and vehicle speed. A correlation between tire pressure and vehicle speed is established, as well as a correspondence between tire pressure and vehicle speed. When 100 different tire pressure or vehicle speed data points are collected, 10 threshold ranges for tire pressure and vehicle speed are constructed, along with a threshold binding relationship between tire pressure and vehicle speed. This constructs a single-point oscillation model). A vehicle speed threshold range that causes uncomfortable or dangerous oscillations is set (based on GPS signals, when the same location experiences oscillations greater than ±20, the vehicle's speed is recorded. A data pool is constructed, and the maximum and minimum values ​​in the data pool are used as the upper and lower limits of the speed threshold, forming a threshold range). When the vehicle is 1,000 meters away from the point causing the vibration (1,500 meters in rainy weather, 2,000 meters in snowy weather) and is traveling towards the vibration point, model verification is initiated. The vehicle's speed is verified; if the speed is outside the threshold range, verification is performed every minute. Once the speed reaches the threshold range or passes the vibration point, verification stops.

[0065] Tire pressure determination range: When constructing a model of a single point causing oscillations on an oscillation map, a vehicle speed threshold range is set to determine the speed at which unpleasant or dangerous oscillations occur. When the vehicle is 1000 meters away from the point causing the oscillation (1500 meters in rainy weather, 2000 meters in snowy weather) and the driving direction is towards the oscillation point, model verification is initiated (based on GPS signals, when oscillations greater than ±10 occur at the same location, the tire pressure of the vehicle at that time is recorded. A data pool is constructed, and the maximum and minimum values ​​in the data pool are used as the upper and lower limits of the tire pressure threshold, forming a threshold range). The vehicle's tire pressure is verified. When the tire pressure reaches the threshold for causing unpleasant or dangerous oscillations, the verification result is that oscillations have occurred. When the tire pressure does not reach the threshold, periodic verification is performed at the same frequency as the vehicle speed.

[0066] As one implementation method, if no vibration occurs when the vehicle passes the vibration point location at a speed and tire pressure that matches the vibration model, the current vibration point location is deleted from the vibration map.

[0067] When multiple drivers are at a vibration point, and based on driving conditions (vehicle speed and tire pressure) and the environment (vehicle location and GPS location passing through the vibration point) they judge that it would cause uncomfortable or dangerous vibrations, but the vehicle does not experience any discomfort or dangerous vibrations, then it is determined that the vibration point has been repaired and there is no longer a need to issue a warning. The vibration point is then removed from the map.

[0068] Specifically, the big data backend cloud platform uses the oscillation model of the oscillation map to verify vehicle speed and tire pressure. If the verification does not cause oscillation, the vehicle speed and tire pressure are read again after one minute for verification.

[0069] When the verification result indicates that vibration will occur, a notification will be sent to the vehicle's audio system.

[0070] When a vehicle passes a vibration point, the driver is alerted. Simultaneously, vehicle speed, tire pressure, and vehicle vibration are recorded and verified against a vibration model. If both vehicle speed and tire pressure reach levels that could cause discomfort or driving hazards, the system checks whether the vehicle experiences any discomfort or dangerous vibrations. If the corresponding vibration occurs, the process ends. If no corresponding vibration occurs, a record is made; when ten consecutive records are made, the vibration point is erased. If no corresponding vibration occurs, and the next vehicle to pass experiences discomfort or dangerous vibrations, the recorded count is cleared.

[0071] Specifically, the control strategies or methods include:

[0072] Tire pressure, vehicle speed, vibration, and GPS signals are recorded by the controller.

[0073] The vehicle communication module uploads the controller signal to the cloud, where it performs verification based on the algorithm model.

[0074] Based on the verification results and the corresponding processing method, the cloud will send timely reminders to the car owner to the main unit audio system.

[0077] The vehicle driving information acquisition module is used to acquire GPS signals, driving direction information, vehicle speed signals and tire pressure signals during vehicle driving.

[0078] The oscillation point detection module is used to compare the vehicle's GPS signal and driving direction information with a pre-drawn oscillation map to determine whether there are oscillation points in the vehicle's driving direction.

[0079] When there is an oscillation point in the vehicle's direction of travel, the current vehicle speed signal and tire pressure signal are compared with the preset oscillation model to determine whether oscillation will occur after passing the corresponding oscillation point and to issue a corresponding oscillation warning.

[0080] As one implementation method, the process of drawing the oscillation map is as follows:

[0081] During vehicle operation, when the vehicle stability value fluctuates beyond the set threshold range, the vehicle's GPS position at this time is recorded, and the current GPS position is used as the oscillation point.

[0082] All oscillation points are plotted on an electronic map to construct an oscillation map.

[0083] The construction process of the oscillation model is as follows:

[0085] Based on the data pools of tire pressure and vehicle speed, the correlation between tire pressure and vehicle speed, as well as the correspondence between tire pressure and vehicle speed, are constructed respectively.

[0086] If no vibration occurs when the vehicle passes the vibration point at a speed and tire pressure that matches the vibration model, the current vibration point location is removed from the vibration map.
