Abstract
Description
Technical Field
[0001] This invention relates to the field of automotive electronics technology, and in particular to a vehicle control method, device, electronic equipment, and vehicle. Background Technology
[0002] A disconnectable stabilizer bar (or electronic disconnecting sway bar) is an advanced suspension technology component designed for specific vehicle models, especially off-road vehicles and SUVs (Sport Utility Vehicles), and is a key technology for modern high-performance off-road vehicles.
[0003] When off-roading, manually disconnecting the stabilizer bar via the in-vehicle HMI (Human Machine Interaction) allows for greater independent movement of the left and right wheels. When one wheel is off-road or encounters uneven terrain, the other wheel remains in contact with the ground, providing necessary traction and grip, thus improving off-road performance. On unpaved roads or very bumpy surfaces, disconnecting the stabilizer bar reduces mutual constraints between suspension components, allowing each wheel to independently handle road undulations, thereby improving ride comfort and reducing body roll and vibration. At high speeds or on smooth roads, manually reconnecting the stabilizer bar restores its ability to control body roll, ensuring vehicle stability and handling during cornering.
[0004] However, for users with limited off-road experience, manually disconnecting and connecting the stabilizer bar is less intelligent, increasing the learning curve. Moreover, manual operation is often only performed on bumpy off-road sections when one wheel is suspended in the air, resulting in low efficiency and a risk of vehicle rollover. Furthermore, the inability to actively connect the stabilizer bar at high speeds or on smooth roads affects driving stability. Summary of the Invention
[0005] In view of this, the present invention aims to provide a vehicle control method, device, electronic device and vehicle to solve the problems that existing stabilizer bars require manual control, which increases the user's learning cost, has low work efficiency and affects driving stability.
[0006] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0027] The target vertical displacement is compared with a second preset value;
[0028] If the vertical displacement of the target is greater than the second preset value, then the target vehicle is determined to be in a bumpy state.

[0037] If the lateral state is less than the target steering urgency level and the road surface adaptation state is a bumpy state, then the disconnectable stabilizer bar driving the target vehicle will disconnect.
[0038] If the lateral state is greater than the target steering urgency level and the road surface adaptation state is non-bumpy, then the disconnectable stabilizer bar of the target vehicle is connected.

[0053] Compared with existing technologies, the vehicle control method, device, electronic equipment, and vehicle described in this invention have the following advantages:
[0054] This invention provides a vehicle control method, device, electronic device, and vehicle, comprising: real-time acquisition of the target vehicle's state information, including target lateral acceleration, first vertical acceleration, first wheel speed, target steering wheel angle, target steering wheel angular velocity, electronic differential lock system control signal, and disconnectable stabilizer bar control signal.

The automatic control of the disconnectable stabilizer bar reduces the user's learning curve and improves vehicle safety and stability. Alternatively, when the target vehicle speed is less than a first preset value, the electronic differential lock system controls the disconnection and connection of the disconnectable stabilizer bar in the target vehicle, providing auxiliary control.

These multiple control methods further ensure the stability of the disconnectable stabilizer bar control. This embodiment of the invention accurately determines the vehicle's state by acquiring vehicle status information and automatically controls the disconnection and connection of the disconnectable stabilizer bar based on the vehicle state, reducing the user's learning curve and improving vehicle safety and stability. Furthermore, the multiple control methods prevent vehicle accidents caused by malfunctions in any single method, further enhancing the stability of the disconnectable stabilizer bar control.

[0062] The technical solutions of the embodiments of the present invention will now be described with reference to the accompanying drawings. Although exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this application can be thoroughly understood and its scope can be fully conveyed to those skilled in the art.
[0063] In various embodiments of the present invention, it should be understood that the sequence number of each process described below does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.
[0064] The vehicle control method, device, electronic equipment, and vehicle provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.
[0065] Reference Figure 1 , Figure 1 This is a flowchart illustrating the steps of a vehicle control method according to an exemplary embodiment:
[0066] Step 101: Real-time acquisition of the target vehicle's status information, including the target lateral acceleration, first vertical acceleration, first wheel speed, target steering wheel angle, target steering wheel angular velocity, electronic differential lock system control signal, and disconnectable stabilizer bar control signal. The target vehicle includes a disconnectable stabilizer bar.
[0067] In this embodiment of the invention, the control signal for the electronic differential lock system is sent through the electronic differential lock system itself. The electronic differential lock is a key component installed on the vehicle's differential. It monitors wheel speeds via the electronic control unit (ECU) and, upon detecting slippage, uses the braking system to brake the slipping wheel, ensuring both drive wheels rotate at the same speed. Even if one wheel is suspended in the air or on a frictionless surface, it ensures the other wheel receives sufficient driving force to help the vehicle get out of trouble or maintain forward movement in adverse road conditions. Typically, when the vehicle is driving off-road or in adverse road conditions, such as mud, sand, snow, or rocky surfaces, the electronic differential lock system activates to ensure power is transmitted to the wheels with traction. The disconnectable stabilizer bar is disconnected during off-road driving to maintain the vehicle's off-road performance. In the same scenario, both the electronic differential lock system and the disconnectable stabilizer bar make decisions, so the control signal from the electronic differential lock system can be used for auxiliary control.
[0068] It should be noted that in this embodiment of the invention, the target lateral acceleration and the first vertical acceleration are obtained through an IMU (Inertial Measurement Unit). An IMU is a sensor with wide applications in many fields. In the automotive industry, it is mainly used to detect and measure the acceleration and rotational motion of objects in three-dimensional space, and is usually installed at the vehicle's center of gravity. By analyzing the IMU sensor data (target lateral acceleration and first vertical acceleration) and combining it with parameters such as steering wheel angle, angular velocity, and vehicle speed, the vehicle's driving state can be obtained more accurately. The control signal for the disconnectable stabilizer bar is implemented through the human-machine interface (HMI). Users can manually control the opening and closing of vehicle components (such as the disconnectable stabilizer bar) in the HMI system. Steering wheel angular velocity refers to the rate at which the steering wheel deflection angle changes over time, that is, the amount of change in the steering wheel deflection angle per unit time. Lateral acceleration refers to the acceleration generated by the vehicle in the lateral direction (perpendicular to the direction of travel) due to the centripetal force during cornering. Vertical acceleration refers to the change in acceleration of the vehicle in the vertical direction (i.e., up and down) due to dynamic behaviors such as vibration, bumps, or jumps.
[0069] Step 102: Determine the target vehicle speed using the first wheel speed; determine the lateral state of the target vehicle using the target lateral acceleration, the target steering wheel angle, and the target steering wheel angular velocity; and determine the road adaptation state of the target vehicle using the first vertical acceleration. The road adaptation state includes bumpy and non-bumpy conditions.
[0070] In this embodiment of the invention, different state information is transmitted through different signals. For example, the target lateral acceleration is transmitted via a lateral acceleration signal, the first vertical acceleration via a vertical acceleration signal, the first wheel speed via a wheel speed signal, the target steering wheel angle via a rudder (also known as steering wheel) angle signal, and the target steering wheel angular velocity via a rudder angular velocity signal. These signals are first input to the signal input unit and then transmitted to other units for processing, ultimately controlling the stabilizer bar to disconnect / connect. For example, ... Figure 2 As shown, the signal input unit acquires the target lateral acceleration, first vertical acceleration, first wheel speed, target steering wheel angle, target steering wheel angular velocity, electronic differential lock system control signal, and disconnectable stabilizer bar control signal. The signal input unit communicates with the MCU (Motor Control Unit) via CANFD (Controller Area Network Flexible Data-rate). The MCU continuously reads data from the CANFD bus (including sensor data and switch signals; sensor data refers to the target lateral acceleration, first vertical acceleration, first wheel speed, target steering wheel angle, and target steering wheel angular velocity; switch signals correspond to the electronic differential lock system control signal and disconnectable stabilizer bar control signal) through polling. The signal input unit transmits the data to the stabilizer bar data unit. The stabilizer bar data unit processes the acquired CANFD sensor data bit by bit and stores it in variables. The longitudinal motion estimation unit then transmits the data to the stabilizer bar data unit. The vehicle speed is estimated by the first wheel speed. The lateral motion estimation unit determines the lateral motion state of the vehicle and the urgency of the driver's steering by the target steering wheel angle, the target steering wheel angular velocity, and the target lateral acceleration. The driving bump estimation unit estimates the vehicle's bump state per unit time by the first vertical acceleration. The stabilizer bar state determination unit determines the control of stabilizer bar disconnection / connection by weighted processing of longitudinal vehicle speed, lateral motion urgency, and driving bump state. This realizes intelligent and automatic opening and closing of the stabilizer bar device under different driving conditions. The electronic differential lock system control signal and the disconnectable stabilizer bar control signal directly control the stabilizer bar disconnection / connection.
[0071] It should be noted that the stabilizer bar data unit acquires data from the CANFD sensors. The wheel speed signal, steering angle signal, steering velocity signal, IMU lateral and vertical acceleration signals, manually controlled disconnectable stabilizer bar control signal, and electronic differential lock system control signal (open / close signal) required for determining the stabilizer bar's disconnection / connection status are all provided by the CANFD bus. These signals are assigned fixed CANFDIDs by the vehicle. The stabilizer bar MCU polls the CAN bus at fixed intervals, assigning the acquired wheel speed signal to the variable Wss, steering angle signal to the variable Was, steering velocity to the variable Wass, lateral acceleration signal to the variable Las, vertical acceleration signal to the variable Vas, electronic stabilizer bar open / close signals to the variable ERC_switch_sign, and differential lock open / close signals to the variable ELD_switch_sign. This provides data for lateral, longitudinal, and vertical bumps, enabling the determination of stabilizer bar open / close. Specifically, Wss represents the wheel speed signal, Was represents the steering angle signal, and Wa represents the steering velocity. ss variable: angular velocity signal variable, Las variable: lateral acceleration signal variable, Vas variable: vertical acceleration signal variable.
[0072] In this embodiment of the invention, the target vehicle speed is determined by the first wheel speed, which is calculated by a longitudinal motion estimation unit. The longitudinal motion estimation unit can estimate the current vehicle speed using the first wheel speed and the wheel diameter. The specific steps include:
[0073] Obtain target information about the target wheels in the target vehicle. The target information includes the number of target wheels, tire diameter, and the second wheel speed of each target wheel.
[0074] The average wheel speed of the target wheel is generated based on the number of wheels and the second wheel speed of each target wheel.
[0075] The target speed of the target vehicle is determined based on the average wheel speed and tire diameter.
[0076] For example, assuming the vehicle is four-wheel drive, the target number of wheels is 4. The second wheel speed includes the right front wheel speed, right rear wheel speed, left front wheel speed, and left rear wheel speed, which are assumed to be 300 RPM, 302 RPM, 298 RPM, and 300 RPM respectively. The tire diameter is 0.6 meters. Then, the average wheel speed = (300 + 302 + 298 + 300) / 4 = 300 RPM. The tire circumference = tire diameter × π = 0.6 meters × 3.14159 ≈ 1.884954 meters. The estimated vehicle speed = average wheel speed × tire circumference = 300 RPM × 1.884954 meters / revolution ≈ 565.4862 meters / minute.
[0077] It should be noted that actual calculations also need to consider factors such as tire slip ratio (i.e., the difference between the actual rolling and ideal rolling of the tire). Assuming a slip ratio of 5%, the actual vehicle speed needs to be adjusted accordingly.
[0078] Actual speed = Estimated speed × (1 - slip ratio) = 33.929172 km / h × 0.95 ≈ 32.2327134 km / h
[0079] The accuracy of the estimate can be improved by taking into account slip ratio and other factors (such as tire wear, road conditions, etc.).
[0080] In addition, this embodiment of the invention also determines the lateral state of the target vehicle through target lateral acceleration, target steering wheel angle, and target steering wheel angular velocity. Lateral state estimation aims to reflect various driving conditions from stable to dangerous. The lateral motion estimation unit estimates the vehicle's lateral state through target lateral acceleration, target steering wheel angle, and target steering wheel angular velocity. The target steering wheel angle can estimate the size of the vehicle's turning angle (θ), and the target steering wheel angular velocity (θ¨) can estimate the driver's initial steering urgency. For example, a lower steering wheel angular acceleration θ¨ indicates smooth operation, while a higher value may mean the driver is making a sharp steering adjustment. A larger steering wheel angle θ indicates a more urgent turn. The target lateral acceleration (α...)... y It can be used to assess cornering stability, such as when the target lateral acceleration ay is less than 0.5 m / s². 2 This indicates that the vehicle is traveling in a straight line or making slight lateral movement, exceeding 1 m / s. 2 This may indicate that the vehicle is making a sharp turn or is experiencing external interference, such as crosswinds or uneven road surfaces. Combining these assessments yields the vehicle's lateral state, which can be categorized using different steering urgency levels. The above steps generate a vehicle steering urgency level table, and then the current vehicle's lateral state is determined by looking up the table based on the vehicle's current data. Specific steps include:
[0081] Different first ranges are pre-set for lateral acceleration, steering wheel rotation angle, and steering wheel angular velocity;
[0082] Different steering urgency levels are determined by a first range and a second range for each steering urgency level, wherein different steering urgency levels correspond to different lateral states;
[0083] The third range is determined by the target's lateral acceleration, the target's steering wheel angle, and the target's steering wheel angular velocity.
[0084] The third range is compared with the second range to determine the lateral state of the target vehicle.
[0085] It should be noted that a steering urgency level table needs to be established before looking up the table. Refer to Table 1, which is the steering urgency level table:
[0086] Table 1: Steering Urgency Level Table
[0087]
[0088] The numerical ranges set above can be varied according to actual circumstances, and this invention does not impose specific limitations on them.
[0089] Furthermore, in this embodiment of the invention, the road adaptation state of the target vehicle is determined by the first vertical acceleration. The road adaptation state includes a bumpy state and a non-bumpy state, calculated by a vehicle bump estimation unit. The vehicle bump estimation unit estimates the road adaptation state using the vertical acceleration obtained from the IMU. Because the IMU sensor is installed at the vehicle's center of gravity, it can more accurately reflect the overall bumpy state of the vehicle. First, the real-time first vertical acceleration is obtained from the IMU. To prevent misjudgment due to individual spike signals and to ensure the accuracy of the original data, a time window concept is introduced. That is, a bumpy state is only determined when the acceleration of multiple consecutive sampling points exceeds a threshold. The vertical acceleration data within the first preset time window are summed using Formula 1 and averaged and filtered to generate the second vertical acceleration.
[0090]
[0091] in, This refers to the second vertical acceleration after smoothing at time point t, a z (i) represents the first vertical acceleration during the time interval from time point t-N+1 to t, where N is the window size for the moving average, i.e., the number of data points used to calculate the average. The choice of window size affects the smoothing effect; a larger window results in a stronger smoothing effect.
[0092] After filtering, the standard deviation of the second vertical acceleration within the second preset time window is calculated using standard deviation calculation formula 2, indicating the degree of fluctuation in acceleration change.
[0093]
[0094] Among them, SD az This refers to the standard deviation of the second vertical acceleration, used as a turbulence indicator. M refers to the second preset time window, the length of the time window used to calculate the standard deviation. This window can be the same size as or different from the first preset time window, depending on the data processing requirements. It refers to the average value of the second vertical acceleration within the second preset time window.
[0095] The vertical displacement is obtained by double integration of the standard deviation of the second vertical acceleration. A vertical displacement threshold, i.e., a second preset value, is set. The second preset value is compared with the target vertical displacement to determine whether the vehicle is in a bumpy state. The specific steps include:
[0096] Collect several first vertical accelerations within the first preset time window;
[0097] A second vertical acceleration is generated by averaging and filtering several first vertical accelerations.
[0098] Obtain several second vertical accelerations within a second preset time window, and generate the standard deviation of the second vertical accelerations;
[0099] The target vertical displacement is generated based on the standard deviation;
[0100] Compare the target vertical displacement with the second preset value;
[0101] If the vertical displacement of the target is greater than the second preset value, it is determined that the target vehicle is in a bumpy state.
[0102] If the vertical displacement of the target is less than the second preset value, the target vehicle is determined to be in a non-bumpy state.
[0103] In summary, the above process estimates the vehicle's longitudinal, lateral, and vertical driving states, such as... Figure 3 As shown, the first wheel speed is input to the longitudinal motion estimation unit to determine the target vehicle speed, the target lateral acceleration, the target steering wheel angle and the target steering wheel angular velocity are input to the lateral motion estimation unit to determine the vehicle's lateral state, and the first vertical acceleration is input to the driving bump estimation unit to determine the road surface adaptation state.
[0104] Step 103: Control the disconnection and connection of the disconnectable stabilizer bar in the target vehicle based on the target vehicle speed, lateral state, and road adaptability; or, if the target vehicle speed is less than a first preset value, control the disconnection and connection of the disconnectable stabilizer bar in the target vehicle based on the electronic differential lock system control signal; or, if the target vehicle speed is less than a first preset value, control the disconnection and connection of the disconnectable stabilizer bar in the target vehicle based on the disconnectable stabilizer bar control signal.
[0105] In this embodiment of the invention, after determining the target vehicle speed, lateral state, and road surface adaptation state, the disconnection and connection of the disconnectable stabilizer bar in the target vehicle can be controlled based on these states. First, the vehicle speed is assessed. When the vehicle speed is too high (greater than a first preset value), the disconnectable stabilizer bar of the target vehicle needs to be activated to improve the vehicle's high-speed stability. At this time, the influence of the lateral state and road surface adaptation state on the vehicle's state, as well as the electronic differential lock system control signal and the disconnectable stabilizer bar control signal, are not considered. To achieve this operation, target weights are set for the lateral state, road surface adaptation state, electronic differential lock system control signal, and disconnectable stabilizer bar control signal. The effectiveness of this information is controlled by adjusting these weights.
[0106] For example, if the vehicle speed is too high (greater than the first preset value), the target weight is set to 0. In this case, the lateral state, road adaptation state, electronic differential lock system control signal, and disconnectable stabilizer bar control signal have no effect on the disconnectable stabilizer bar. When the vehicle speed is less than the first preset value, the target weight is set to 1. This allows the lateral state, road adaptation state, electronic differential lock system control signal, and disconnectable stabilizer bar control signal to be considered in relation to the disconnectable stabilizer bar. The specific steps include:
[0107] Pre-set target weights, which include a first weight and a second weight;
[0108] If the target weight is the first weight, then the lateral state, road adaptation state, electronic differential lock system control signal and disconnectable stabilizer bar control signal are invalid for the control of the disconnectable stabilizer bar.
[0109] If the target weight is the second weight, then the lateral state, road adaptation state, electronic differential lock system control signal, and disconnectable stabilizer bar control signal are determined to be effective for controlling the disconnectable stabilizer bar.
[0110] After assessing the longitudinal state's impact on the disconnectable stabilizer bar, the lateral and vertical influences are considered. If the target vehicle speed is less than a first preset value, the road surface is bumpy, and the lateral state is less than the target steering urgency level, the drive IC is controlled to disconnect the stabilizer bar system to ensure vehicle passability on bumpy roads at low speeds. Conversely, if the target speed is higher than the preset value, the drive IC is controlled to connect the stabilizer bar system, indicating that the vehicle is currently in a low-speed, large-angle turning condition and the stabilizer bar cannot be disconnected to maintain vehicle turning stability. The specific steps include:
[0111] If the target vehicle speed is greater than the first preset value, the target weight is set to the first weight, and the disconnectable stabilizer bar of the target vehicle is activated.
[0112] If the target vehicle speed is less than the first preset value, the target weight is set to the second weight, and the lateral state and road surface adaptation state are determined.
[0113] If the lateral condition is less than the target steering urgency level and the road surface condition is bumpy, then the disconnectable stabilizer bar driving the target vehicle will disconnect.
[0114] If the lateral condition is greater than the target steering urgency level and the road surface condition is non-bumpy, then the disconnectable stabilizer bar of the target vehicle is connected.
[0115] In addition, the disconnectable stabilizer bar in the target vehicle can be controlled via the electronic differential lock system control signal. The specific steps include:
[0116] When the target vehicle speed is less than a first preset value, determine the operating status of the electronic differential lock system control signal;
[0117] If the electronic differential lock system control signal is in the differential lock activation state, the disconnectable stabilizer bar of the target vehicle will disconnect.
[0118] In addition, users can manually control the disconnectable stabilizer bar control signal to drive the disconnectable stabilizer bar of the target vehicle to disconnect and connect.
[0119] The above process can be achieved through Figure 4 This means that the target vehicle speed is compared with the first preset value. If it is greater than the target speed, the weights of Ka, Kb, Kc, and Kd in the weighted windows A and B are adjusted to be invalid. If it is less than the target speed, the weights are adjusted to be valid. Then, the lateral state judgment and road adaptation state judgment are performed to drive the IC to control the stabilizer bar. In addition, the IC can also be driven to control the stabilizer bar by controlling the disconnectable stabilizer bar control signal and the electronic differential lock system control signal.

The automatic control of the disconnectable stabilizer bar reduces the user's learning curve and improves vehicle safety and stability. Alternatively, when the target vehicle speed is less than a first preset value, the electronic differential lock system controls the disconnection and connection of the disconnectable stabilizer bar in the target vehicle, providing auxiliary control. Or, when the target vehicle speed is less than a first preset value, the disconnectable stabilizer bar control signal controls the disconnection and connection of the disconnectable stabilizer bar in the target vehicle.
