[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and 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.
[0041] During vehicle operation, the vehicle's passenger compartment and every object within it are subject to gravity. Effectively, the gravitational forces acting on all parts of the vehicle are concentrated at a single point, the center of gravity. To maintain balance during operation, the tires on both sides of the vehicle experience uniform force, which is counteracted by the reaction force from the ground, thus maintaining the vehicle's equilibrium.
[0042] However, during vehicle operation, especially during high-speed turns, the vehicle's center of gravity may shift from its original position, moving towards the outer tires. This uneven distribution of force between the tires creates torque that is unbalanced with the vehicle's gravitational torque. Consequently, the vehicle cannot maintain its balance, ultimately leading to a rollover accident.
[0043] Therefore, this application provides a vehicle balance control method applied to a vehicle center of gravity control system, which adjusts the vehicle's center of gravity through external force, so that the vehicle maintains a balanced state during driving and reduces the probability of vehicle rollover accidents.
[0044] Reference Figure 1 This document illustrates an optional flowchart of a vehicle balance control method provided in an embodiment of this application. The vehicle balance control method can be applied to a controller of a vehicle center of gravity control system installed on a vehicle. The vehicle center of gravity control system may further include an electromagnetic induction device installed at a predetermined location within the vehicle compartment. This electromagnetic induction device can be a magnetic induction coil, an inductor coil, or similar device, which generates a magnetic field based on a current-carrying conductor, producing a magnetic force F. The magnitude of the magnetic field is controlled by controlling the current in the current-carrying conductor, thereby controlling the magnitude of the magnetic force F. In this embodiment, the magnetic force F generated by the electromagnetic induction device is used to change the force state of the vehicle, thereby adjusting the vehicle's center of gravity position and maintaining the vehicle's balance.
[0045] The predetermined positions include at least two symmetrical positions located on either side of the vehicle's centerline, where the vehicle centerline is a straight line passing through the center of the rectangular base of the carriage and parallel to the vehicle's direction of travel. Figure 2 The diagram shows a projection of the bottom surface of a vehicle body. Typically, the bottom surface of a vehicle chassis or vehicle body is designed as a rectangle. The rectangle in the diagram is a projection of the bottom surface of the vehicle chassis or vehicle body. a, b, c, d, e, and f in the diagram are electromagnetic induction devices.
[0046] In this embodiment of the application, the center of the rectangle is used as the coordinate reference point, the straight line passing through the center and parallel to the vehicle's driving direction is used as the vehicle centerline, and the straight line passing through the center and perpendicular to the vehicle centerline is used as the vertical centerline. The two positions can be located at two positions symmetrical about the centerline on the rectangular bottom surface of the carriage.
[0047] Optionally, the two locations are situated at the two intersections of the vertical centerline and the rectangular base of the carriage. The vertical centerline is a straight line passing through the center of the rectangular base of the carriage and perpendicular to the vehicle's centerline. Therefore, the electromagnetic induction device installed at the predetermined location in the carriage comprises two electromagnetic induction devices respectively installed at the two intersections of the vertical centerline and the rectangular base of the carriage. It can be understood that the two locations described above are... Figure 2 The two positions of e and f in the middle of the rectangle.
[0048] This application embodiment is not limited to installing two electromagnetic induction devices; optionally, four or more electromagnetic induction devices may be installed. For example, the two positions located at the two symmetrical apex corners of the rectangular bottom surface of the carriage about the vehicle centerline also include two other apex corners of the rectangular bottom surface of the carriage; the electromagnetic induction devices installed at the predetermined positions in the carriage include: four electromagnetic induction devices respectively installed at the four apex corners of the rectangular bottom surface of the carriage. It is understood that the positions described above are located at... Figure 2 The two positions of a, b, c, and d are shown.
[0049] Reference Figure 1 The specific process of the vehicle balance control method corresponding to the above-mentioned vehicle center of gravity control system will be described, and the process may include:
[0050] Step S110: Obtain the center of gravity position of the vehicle in its current state and the center of gravity position of the vehicle in its balanced state.
[0051] The vehicle's center of gravity position in its balanced state typically remains unchanged. When the vehicle's current center of gravity position coincides with the center of gravity position in its balanced state, it ensures that the vehicle's tires receive uniform force, preventing imbalance due to uneven force distribution. In this embodiment, the vehicle's center of gravity position in its balanced state can be obtained during vehicle operation.
[0052] The vehicle's center of gravity position in its current state is related to the vehicle's geometry and the mass distribution of objects inside the vehicle. The vehicle's geometry is usually fixed, so the main factors affecting the center of gravity are the mass distribution of passengers, cargo, and other objects inside the vehicle. However, during vehicle operation, cargo may shift or sway within the vehicle due to unstable placement, affecting the mass distribution and causing a change in the vehicle's center of gravity position.
[0053] To ensure vehicle driving safety, this embodiment acquires the vehicle's center of gravity position in real time during operation. The vehicle's center of gravity position can be obtained using a gyroscope positioned at the center of the vehicle or the center of the passenger compartment. The current center of gravity position is calculated by the gyroscope based on the vehicle's driving parameters, which include at least: vehicle speed, steering wheel angle, and vehicle acceleration. The gyroscope, also known as an angular velocity sensor, can calculate the current vehicle center of gravity position based on the collected vehicle driving parameters such as vehicle speed, steering wheel angle, and acceleration.
[0054] Step S120: Determine the center of gravity offset distance of the vehicle based on the center of gravity position of the vehicle in its current state and the center of gravity position of the vehicle in its balanced state.
[0055] In the embodiments of this application, it can be used as Figure 2 Using the center shown as the origin of the coordinate system, a three-dimensional spatial coordinate system is established. Then, the center of gravity position of the vehicle in its current state and the center of gravity position of the vehicle in its balanced state are three-dimensional coordinate points. When determining the center of gravity offset distance between the two, the straight-line distance between the two three-dimensional coordinate points can be directly calculated.
[0056] For example, if the coordinates of the center of gravity of the vehicle in its current state are (x1, y1, z1) and the coordinates of the center of gravity of the vehicle in its balanced state are (x2, y2, z2), then the formula for calculating the center of gravity offset distance can be the following formula (1):
[0057]
[0058] Step S130: Determine whether the center of gravity offset distance meets the preset balance condition. If the preset balance condition is not met, proceed to step S140. If the preset balance condition is met, the vehicle's center of gravity does not need to be adjusted and the current state can be maintained to continue driving.
[0059] Step S140: Adjust the current of the electromagnetic induction device so that the magnetic force generated by the electromagnetic induction device adjusts the center of gravity position of the vehicle in its current state until the center of gravity offset distance corresponding to the adjusted center of gravity position of the vehicle in its current state meets the preset balance condition.
[0060] In this embodiment, at least one electromagnetic induction device is installed on each side of the centerline. Alternatively, one electromagnetic induction device can be installed at each of the four apex corners of the rectangle. By adjusting the magnitude of the magnetic force at the four corners of the carriage, the tilt angle of the carriage can be adjusted, thereby changing the position of the vehicle's center of gravity.
[0061] The process of adjusting the vehicle's center of gravity position using an electromagnetic induction device in this application embodiment may include: when the center of gravity offset distance does not meet a preset balance condition, determining the offset direction and the opposite offset direction of the vehicle's center of gravity position in the current state; controlling the current of the electromagnetic induction device corresponding to the offset direction to increase and the current of the electromagnetic induction device corresponding to the opposite offset direction to decrease, so that the magnetic force generated by the electromagnetic induction device adjusts the center of gravity position of the vehicle in the current state, thereby obtaining the adjusted center of gravity position of the vehicle; and determining the adjusted center of gravity offset distance based on the adjusted center of gravity position of the vehicle and the center of gravity position of the vehicle in a balanced state.
[0062] When the adjusted center of gravity offset distance meets the preset balance condition, the control of the current of the electromagnetic induction device is stopped; when the adjusted center of gravity offset distance does not meet the preset balance condition, the steps of determining the offset direction and the opposite offset direction of the center of gravity position of the vehicle in the current state are executed until the adjusted center of gravity offset distance meets the preset balance condition.
[0063] Reference Figure 3 The diagram shown is an application example of the vehicle balance control method provided in this application embodiment. Figure 3 This can be understood as a schematic diagram of the carriages projected from the rear of the vehicle. The diagram includes: 10 carriages, 20 gyroscopes, and two 30 electromagnetic induction devices, labeled a and b. The dotted line in the diagram represents the balance line. When the swaying range of carriage 10 remains within the preset range of the balance line, carriage 10 can maintain balance. The swaying range can be represented by the distance of the center of gravity offset.
[0064] However, when the vehicle's center of gravity shifts beyond the preset balance condition, it proves that the 10-carriage compartment has seriously deviated from the balance line and cannot maintain a balanced state. In this embodiment, the preset balance condition can be a threshold for the allowable center of gravity shift distance. Assuming the allowable center of gravity shift distance threshold is 10mm, when the center of gravity shift distance is not less than 10mm, it can be determined that the center of gravity shift distance does not meet the preset balance condition, and the vehicle is currently unbalanced.
[0065] Vehicle imbalance can cause the vehicle to veer severely to one side of the balance line, such as... Figure 2 As shown, carriage 10 has clearly shifted at an angle, with the entire carriage tilted to the left. Therefore, the left side of the vertical balance line can be determined as the direction of the shift, and the right side can be determined as the opposite direction of the shift.
[0066] Based on the direction of the offset, it can be seen that the pressure on the left and right sides of the vehicle is uneven, with the left side experiencing a greater force than the right side. To maintain the balance between the two sides, the pressure on the left side can be reduced, and / or the pressure on the right side can be increased at the same time, so that the force on both sides is even.
[0067] Based on the above concept, this embodiment of the application increases the current of the electromagnetic induction device in the offset direction, causing the electromagnetic induction device in the offset direction, i.e., the left electromagnetic induction device, to generate an upward magnetic force. As the current increases, the magnetic force also increases, and this magnetic force can cancel out the pressure on the left side, thereby reducing the pressure on the left side. At the same time, the current of the electromagnetic induction device in the opposite offset direction can be reduced, thereby reducing the magnetic force generated by the right electromagnetic induction device. The reduction in the magnetic force on the right side will reduce the pressure canceled out on the right side, thus increasing the pressure on the right side.
[0068] like Figure 3 By controlling the current of electromagnetic induction device a in the offset direction and electromagnetic induction device c on the same side (not shown), a and c generate a magnetic force F, which counteracts the downward pressure in the offset direction. Electromagnetic induction device b in the opposite offset direction and electromagnetic induction device d on the same side (not shown) can be controlled or not. If b and d are not controlled, and a, b, c, and d are controlled simultaneously, the adjustment speed of the vehicle's center of gravity will be faster, further reducing the probability of vehicle rollover.
[0069] As the pressure on both sides changes, the center of gravity of the vehicle or carriage also changes accordingly. In this embodiment of the application, when adjusting the forces on both sides through the electromagnetic induction device, the center of gravity position of the vehicle can be obtained in real time through a gyroscope, and the center of gravity offset distance between the adjusted center of gravity position and the center of gravity position in the vehicle's balanced state can be calculated. When the center of gravity offset distance meets the preset balance condition, the current control of the electromagnetic induction device is stopped to avoid missing the current or force state that can keep the vehicle in balance.
[0070] If the center of gravity offset distance does not meet the preset balance condition, the current of the electromagnetic induction device will continue to be controlled to adjust the center of gravity position of the vehicle or carriage.
[0071] In summary, this embodiment calculates the offset distance between the current vehicle center of gravity and the center of gravity position in the vehicle's balanced state, compares this offset distance with preset balance conditions, and if the preset balance conditions are not met, the vehicle cannot maintain its balance and is at risk of overturning. Furthermore, the current in the electromagnetic induction device can be controlled to generate magnetic force. This magnetic force can adjust the offset angles of the vehicle's four corners, thereby adjusting the vehicle's center of gravity position and ensuring that the offset distance between the adjusted center of gravity position and the center of gravity position in the vehicle's balanced state meets the preset balance conditions, thus preventing the vehicle from becoming unbalanced and overturning.
[0072] The vehicle balance control device provided in the embodiments of this application is described below. The vehicle balance control device described below can be referred to in correspondence with the vehicle balance control method described above.

[0077] This application embodiment compares the offset distance between the current vehicle center of gravity position and the center of gravity position under balanced conditions with preset balance conditions to determine whether there is a risk that the vehicle cannot maintain balance. It then determines whether to control the current of the electromagnetic induction device to adjust the vehicle's center of gravity position. The current causes the electromagnetic induction device to generate magnetic force, which adjusts the vehicle's offset angle, thereby adjusting the vehicle's center of gravity position. This ensures that the offset distance between the adjusted center of gravity position and the center of gravity position under balanced conditions meets the preset balance conditions, preventing the vehicle from becoming unbalanced and overturning.
