Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] The flowchart shown in the attached diagram is for illustrative purposes only and does not necessarily include all content and operations / steps, nor does it necessarily have to be performed in the order described. For example, some operations / steps can be broken down, combined, or partially merged, so the actual execution order may change depending on the actual situation.

[0045] This application provides a control method, system, and vehicle for mitigating the bumps and jolts of a vehicle when going over speed bumps. The control method for mitigating the bumps and jolts of a vehicle when going over speed bumps can be applied to vehicles.

[0046] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0047] Please refer to Figure 1 , Figure 1 This is a flowchart illustrating a control method for mitigating vehicle bumps when going over speed bumps, provided as an embodiment of this application.

[0048] like Figure 1 As shown, the method includes step S101.

[0049] Step S101: By collecting road surface information, determine the acceleration and acceleration time of the front axle of the vehicle, and the deceleration and deceleration time of the rear axle of the vehicle, thereby activating the control module to control the acceleration of the front axle of the vehicle at the acceleration time and the deceleration of the rear axle of the vehicle at the deceleration time. The road surface information includes the height of the speed bump and the distance between the speed bump and the vehicle.

[0050] As an example, a pre-set data acquisition device collects road information in front of the vehicle, including the height of speed bumps and the distance between the speed bump and the vehicle. Based on the collected data on the speed bump height and distance, the acceleration and acceleration timing of the vehicle's front axle, as well as the deceleration and deceleration timing of the vehicle's rear axle, are determined. For example, the acceleration and acceleration timing of the front axle are determined by the height of the speed bump, and the deceleration and deceleration timing of the rear axle are determined by the distance between the speed bump and the vehicle. This activates the control module, which controls the acceleration of the front axle during acceleration and the deceleration of the rear axle during deceleration.

[0051] Specifically, determining the acceleration and acceleration time of the vehicle's front axle, and the deceleration and deceleration time of the vehicle's rear axle, based on the collected road surface information, includes: detecting whether there is a speed bump ahead using a preset vehicle radar; if a speed bump is detected ahead, collecting road surface information ahead using a preset camera; determining the acceleration of the vehicle's front axle and the deceleration of the vehicle's rear axle based on the height of the speed bump; and determining the acceleration time of the vehicle's front axle and the deceleration time of the vehicle's rear axle based on the distance between the speed bump and the vehicle.

[0052] An exemplary method involves using a radar pre-installed in front of the vehicle to detect speed bumps on the road surface ahead of the vehicle in real time or at set intervals. For example, this radar could be an ultrasonic radar, emitting sound waves to detect speed bumps in real time or at set intervals. If the emitted sound waves are received, a speed bump is identified; otherwise, it is determined that no speed bump exists. Once a speed bump is identified, a pre-installed camera captures an image of the road surface ahead, which is then analyzed to obtain road information. This analysis includes using a pre-set neural network model to predict the road surface information from the image. The road information includes the height of the speed bump and the distance between the speed bump and the vehicle. The distance between the speed bump and the vehicle includes the distance between the speed bump and the front axle and the rear axle.

[0053] Based on the height of the speed bump, determine the acceleration of the front axle and the deceleration of the rear axle of the vehicle. For example, obtain a first preset reference table and a second preset reference table, match the speed bump height with the first preset reference table, obtain a first speed in the first preset reference table that matches the speed bump height, and use this first speed as the acceleration of the front axle of the vehicle; match the speed bump with the second preset reference table, obtain a second speed in the second preset reference table that matches the speed bump height, and use this second speed as the deceleration of the rear axle of the vehicle.

[0054] Based on the distance between the speed bump and the vehicle, the acceleration time of the front axle and the deceleration time of the rear axle are determined. The distance between the speed bump and the vehicle includes both the distance between the speed bump and the front axle and the distance between the speed bump and the rear axle. For example, a third preset reference table and a fourth preset reference table are obtained. The distance between the speed bump and the front axle is matched with the time in the third preset reference table, and the first matching time is taken as the acceleration time of the front axle. Similarly, the distance between the speed bump and the rear axle is matched with the fourth preset reference table, and the second matching time is taken as the deceleration time of the rear axle.

[0055] Specifically, determining the acceleration of the front axle and the deceleration of the rear axle of the vehicle based on the height of the speed bump includes: obtaining the current vehicle speed; and determining the acceleration of the front axle and the deceleration of the rear axle of the vehicle based on the current vehicle speed and the height of the speed bump.

[0056] As an example, the current vehicle speed is obtained, and the acceleration of the front axle and the deceleration of the rear axle are determined based on the current vehicle speed and the speed bump height. For instance, if the current vehicle speed is less than a preset speed, a first speed matching the speed bump height in a first preset reference table is obtained, and this first speed is used as the acceleration of the front axle; if the current vehicle speed is greater than or equal to the preset speed, a second speed matching the speed bump height in a second preset reference table is obtained, and this second speed is used as the deceleration of the rear axle.

[0057] Specifically, determining the acceleration of the front axle and the deceleration of the rear axle of the vehicle based on the current vehicle speed and the speed bump height includes: obtaining a first initial quantity reference table and a second initial quantity reference table; matching the current vehicle speed and the speed bump height with the first initial quantity reference table, and using the matched acceleration as the acceleration of the front axle of the vehicle; matching the current vehicle speed and the speed bump height with the second initial quantity reference table, and using the matched acceleration as the deceleration of the rear axle of the vehicle.

[0058] As an example, a first initial quantity reference table and a second initial quantity reference table are obtained, wherein the first initial quantity reference table is shown below:

[0059] X 30mm 50mm 70mm 110mm 5km / h 0.05 0.07 0.09 0.1 10km / h 0.07 0.09 0.1 0.1 20km / h 0.09 0.1 0.12 0.12 30km / h 0.1 0.1 0.12 0.15 50km / h 0.12 0.12 0.15 0.15 80km / h 0.12 0.15 0.15 0.2 100km / h 0.15 0.15 0.2 0.2

[0060] The x-value is determined by two factors: the height of the speed bump and the vehicle speed. The initial values ​​for calibration are shown in the table above. Rows and columns represent the speed bump height in mm; vertical columns represent the vehicle speed in km / h; initial values ​​for x in the table are in g (acceleration due to gravity).

[0061] For example, if a vehicle is given an acceleration x, the axle load on the front axle becomes: F z1 = mg*b-mx, where F z1 Let m be the front axle load, g be the vehicle mass, b be the distance from the center of gravity to the rear axle, and x be the acceleration of the vehicle's front axle. Therefore, the vehicle deceleration x value can be set as a follow-up momentum based on the speed bump height and vehicle speed to improve vehicle comfort under different operating conditions.

[0062] The reference table for the second initial quantity is shown below:

[0063] X 30mm 50mm 70mm 110mm 5km / h -0.05 -0.07 -0.09 -0.1 10km / h -0.07 -0.09 -0.1 -0.1 20km / h -0.09 -0.1 -0.12 -0.12 30km / h -0.1 -0.1 -0.12 -0.15 50km / h -0.12 -0.12 -0.15 -0.15 80km / h -0.12 -0.15 -0.15 -0.2 100km / h -0.15 -0.15 -0.2 -0.2

[0064] The x-value is determined by two factors: the height of the speed bump and the vehicle speed. The initial values ​​for calibration are shown in the table above. Rows and columns represent the speed bump height in mm; vertical columns represent the vehicle speed in km / h; initial values ​​for x in the table are in g (acceleration due to gravity).

[0065] For example, if a vehicle is required to decelerate by a speed x, the axle load on the front axle becomes: F z2 = mg*a-mx, where F z2 Let m be the rear axle load, g be the vehicle mass, a be the gravitational acceleration, a be the distance from the center of gravity to the front axle, and x be the acceleration of the vehicle's front axle. Therefore, the vehicle deceleration x value can be set as a follow-up momentum based on the speed bump height and vehicle speed to improve vehicle comfort under different operating conditions.

[0066] Specifically, determining the acceleration time of the front axle and the deceleration time of the rear axle of the vehicle based on the distance between the speed bump and the vehicle includes: determining the distance between the speed bump and the front axle of the vehicle and the distance between the speed bump and the rear axle of the vehicle based on the distance between the speed bump and the vehicle; determining the acceleration time of the front axle of the vehicle based on the distance between the speed bump and the front axle of the vehicle; and determining the deceleration time of the rear axle of the vehicle based on the distance between the speed bump and the rear axle of the vehicle.

[0067] As an example, the distance between the speed bump and the vehicle is obtained, and this distance is used as the distance between the speed bump and the vehicle's front axle. The distances between the front and rear axles are also obtained, and the distance between the speed bump and the rear axle is derived from these distances. A pre-set neural network model is used, and the distance between the speed bump and the front axle is input into the model to obtain the acceleration time of the front axle; similarly, the distance between the speed bump and the rear axle is input into the model to obtain the deceleration time of the rear axle. The pre-set neural network model is obtained by pre-training with training data.

[0068] Specifically, determining the acceleration time of the vehicle's front axle based on the distance between the speed bump and the vehicle's front axle includes: acquiring the current vehicle speed and the current time; calculating a first duration based on the current vehicle speed and the distance between the speed bump and the vehicle's front axle; and determining the acceleration time of the vehicle's front axle using the current time and the first duration.

[0069] As an example, the current vehicle speed and current time are obtained. By dividing the distance between the speed bump and the vehicle's front axle by the current vehicle speed, the time it takes for the vehicle's front axle to travel to the speed bump is obtained. This time is used as the first time. The acceleration time of the vehicle's front axle is obtained by combining the first time and the current time. For example, the acceleration time of the vehicle's front axle is obtained by adding the first time to the current time.

[0070] Specifically, determining the deceleration time of the vehicle's rear axle based on the distance between the speed bump and the vehicle's rear axle includes: acquiring the current vehicle speed and the current time; calculating a second duration based on the current vehicle speed and the distance between the speed bump and the vehicle's rear axle; and determining the deceleration time of the vehicle's rear axle using the current time and the second duration.

[0071] As an example, the current vehicle speed and current time are obtained. By dividing the distance between the speed bump and the vehicle's rear axle by the current vehicle speed, the time it takes for the rear axle to travel to the speed bump is obtained. This time is used as a second time. By combining the second time and the current time, the deceleration time of the rear axle is obtained. For example, adding the second time to the current time gives the deceleration time of the rear axle.

[0072] In this embodiment, by collecting road surface information, the acceleration and acceleration time of the front axle of the vehicle, as well as the deceleration and deceleration time of the rear axle of the vehicle, are determined. This activates the control module, which controls the acceleration of the front axle at the acceleration time and the deceleration of the rear axle at the deceleration time. The system intelligently identifies speed bumps and then controls the acceleration and deceleration of the vehicle to achieve load transfer between the front and rear axles. This reduces the energy value of the impact between the tires and the deceleration, reduces the load on the vehicle's suspension damping system, and ultimately improves the vehicle's ride comfort.

[0074] like Figure 2 As shown, the system includes: an information acquisition module 401, a determination module 402, and a control module 403.

[0075] Information acquisition module 401 is used to collect road surface information;

[0076] The determination module 402 is used to determine the acceleration and acceleration time of the front axle of the vehicle, and the deceleration and deceleration time of the rear axle of the vehicle.

[0077] The control module 403 is used to control the acceleration of the front axle of the vehicle during acceleration and the deceleration of the rear axle of the vehicle during deceleration.
