[0015] If the current gear is in any gear of the intermediate gear group, then based on the correspondence between the force and the solenoid valve state, the state of the target solenoid valve corresponding to the first force is determined as follows: both the first and second solenoid valves at both ends of the gear selection piston are in the open state, and the opening degree of the first solenoid valve is the third opening degree, and the opening degree of the second solenoid valve is the fourth opening degree; wherein, the difference between the force of the gas introduced based on the third opening degree and the force of the gas introduced based on the fourth opening degree is the second force.

[0040] Given the explosive growth of AMT (Automated Manual Transmission) technology in the domestic commercial vehicle market, as it eliminates the need for driver operation, significantly reducing labor intensity and improving fuel economy, AMT has great development potential in commercial vehicles. However, due to the complexity of AMT, abnormal situations may occur when encountering complex road conditions. For example, during low-speed, high-angle turns, the shifting piston of the AMT's gear-shifting actuator may shift due to centrifugal force. This application proposes a vehicle gear control method, device, and electronic equipment that can improve the stability of the shifting piston in the gear-shifting position, ensuring stable turning while enhancing the reliability and comfort of the AMT.

[0041] Other features and advantages of this application will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the application. The objectives and other advantages of this application may be realized and obtained by means of the structures particularly pointed out in the written description, claims, and drawings.

[0042] The method for controlling vehicle gears in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0043] Figure 1 This application illustrates a schematic flowchart of a vehicle gear control method, including:

[0044] Step 101: If no gear adjustment signal is detected during vehicle turning, and the centrifugal force of the vehicle is greater than a preset threshold, then based on the correspondence between gear, centrifugal force, and force, determine the first force of the centrifugal force of the vehicle acting on the gear selector piston of the gearbox.

[0045] Specifically, when the vehicle control unit (VCU) receives a turning signal, if it does not detect a change in gear position (e.g., the gear was 3rd before the turn), it does not need to change gears and continues to maintain 3rd gear during the turn. The centrifugal force experienced by the vehicle due to the turn is then determined.

[0046] As an optional implementation, the vehicle is equipped with a gyroscope, and the centrifugal force is determined by: acquiring the turning angle value detected by the gyroscope; and determining the centrifugal force corresponding to the current vehicle speed and the turning angle value based on a preset relationship between vehicle speed, turning angle and centrifugal force.

[0047] It should be noted that the turning angle value can be detected by a gyroscope or determined by monitoring the direction of steering wheel rotation. Once the turning angle value is determined, it is based on a preset relationship between vehicle speed, turning angle, and centrifugal force. This preset relationship can be a table mapping vehicle speed, turning angle, and centrifugal force, for example, when the vehicle speed is 'a', the turning angle is 'b', and the corresponding centrifugal force is 'c'; or it can be a table mapping vehicle speed range, turning angle, and centrifugal force, for example, if the vehicle speed is within the range of 'ab', and the turning angle is 'd', the corresponding centrifugal force is 'e'. There are no restrictions on the preset relationship here.

[0048] Once the magnitude of the centrifugal force is determined in the above manner, the direction of the centrifugal force is opposite to the turning direction. That is, when the vehicle turns left, the centrifugal force acting on the vehicle is to the right; when the vehicle turns right, the centrifugal force acting on the vehicle is to the left.

[0049] When a vehicle is subjected to centrifugal force, the gear selector piston is also subjected to centrifugal force in the same direction as the vehicle, causing the gear shifting process to be retried, resulting in power interruption and affecting the reliability of the AMT and the stability of the vehicle when cornering. Based on the pre-set correspondence between gear, centrifugal force, and applied force, the first applied force is determined. For example, when the gear is 3rd gear, the centrifugal force is a force of magnitude 'a' directed to the left, and the corresponding first applied force of the vehicle's centrifugal force acting on the gear selector piston of the gearbox is a force of magnitude 'b' directed to the left.

[0050] Step 102: Based on the correspondence between the applied force and the solenoid valve state, determine the state of the target solenoid valve corresponding to the first applied force.

[0051] Specifically, the state of a solenoid valve includes whether the solenoid valve is open or closed, and the degree of opening when the solenoid valve is open.

[0052] As an optional implementation, in this embodiment of the application, a first edge gear group, a middle gear group, and a second edge gear group are sequentially arranged along the gearbox. See also Figure 2 When the gear selection direction is perpendicular to the vehicle's driving direction, the gear group settings may include, but are not limited to, reverse gear and 1st gear; the middle gear group includes 2nd gear and 3rd gear; and the second edge gear group includes 4th gear and 5th gear.

[0053] Step 103: Control the target solenoid valve according to its state to generate a second force acting on the gear selection piston. The first force and the second force are of the same magnitude but opposite in direction. A solenoid valve is provided at each end of the gear selection piston. The state of the solenoid valve includes its open / closed state and its opening degree.

[0054] Based on the correspondence between the applied force and the solenoid valve state, the state of the target solenoid valve corresponding to the first applied force can be determined in three cases:

[0055] Scenario 1: If the current gear is any gear in the first edge gear group, and the direction of the first force is opposite to the first pointing direction, then based on the correspondence between the force and the solenoid valve state, the state of the target solenoid valve corresponding to the first force is determined as follows: the solenoid valve in the target direction of the gear selection piston is in the open state, and the opening degree of the solenoid valve is the first opening degree. Wherein, the target direction is the same as the direction of the centrifugal force, the first pointing direction is the direction from the middle gear group to the first edge gear group, the difference between the first solenoid valve force and the first edge force is the second force, the first solenoid valve force is the force of the gas introduced based on the first opening degree, the first edge force is the force of the first edge wall of the gear box on the gear selection piston, and the first edge gear group is attached to the first edge wall of the gear box.

[0056] Specifically, if the current gear is reverse or 1st gear, the first pointing direction is left. For example, when the vehicle turns left, it experiences a centrifugal force to the right, and similarly, the shift piston experiences a first force to the right. See [link to relevant documentation]. Figure 3At this point, the target direction is to the right. The vehicle controller energizes the first solenoid valve on the right side of the gear selector piston, opening it and allowing air to enter through the first air intake port. The difference between the force exerted by the gas introduced at the first opening and the force exerted by the first edge wall of the gearbox on the gear selector piston is the final second force. When the gear selector piston is subjected to this second force, it will avoid deflection and stably maintain its position in the current gear.

[0057] Scenario 2: If the current gear is any gear in the second edge gear group, and the direction of the first force is the same as the second pointing direction, then based on the correspondence between the force and the solenoid valve state, the state of the target solenoid valve corresponding to the first force is determined as follows: the solenoid valve in the target direction of the gear selection piston is in the open state, and the opening degree of the solenoid valve is the second opening degree. Here, the target direction is the same as the direction of the centrifugal force, the second pointing direction is the direction from the middle gear group to the second edge gear group, the sum of the second solenoid valve force and the second edge force is the second force, the second solenoid valve force is the force of the gas introduced based on the second opening degree, the second edge force is the force of the second edge wall of the gear box on the gear selection piston, and the second edge gear group is attached to the second edge wall of the gear box.

[0058] Specifically, if the current gear is 4th or 5th, and the second direction of reference is to the right, for example, when the vehicle turns left, it experiences a centrifugal force to the right. Similarly, the shift piston experiences a second force to the right. Since the target direction is to the right, the vehicle controller energizes the first solenoid valve on the right side of the shift piston, opening it and allowing air to enter through the first air intake port on the right. This means that the force of the air intake and the force exerted on the shift piston by the second edge wall of the gearbox simultaneously provide force to the shift piston, preventing it from shifting and ensuring it remains stably in the current gear. Therefore, the sum of the force of the gas introduced at the second opening and the force exerted on the shift piston by the second edge wall of the gearbox constitutes the final second force.

[0059] When the second direction points to the left, for example when a vehicle turns right, the vehicle experiences a centrifugal force to the left. Similarly, the shift piston experiences a second force to the left. See [link to relevant documentation]. Figure 4 At this time, the target direction is to the left. The vehicle controller controls the second solenoid valve on the left side of the gear selector piston to be energized, so that the second solenoid valve on the left side is in the open state. The second air intake on the left side opens to allow air to enter. That is, the force of the air intake on the left side provides force to the gear selector piston, so that the gear selector piston will avoid deflection after being subjected to the second force and will stably maintain the current gear position.

[0060] Scenario 3: If the current gear is in any gear of the intermediate gear group, then based on the correspondence between the force and the solenoid valve state, the state of the target solenoid valve corresponding to the first force is determined as follows: both the first and second solenoid valves at both ends of the gear selection piston are in the open state, and the opening degree of the first solenoid valve is the third opening degree, and the opening degree of the second solenoid valve is the fourth opening degree; wherein, the difference between the force of the gas introduced based on the third opening degree and the force of the gas introduced based on the fourth opening degree is the second force.

[0061] Specifically, if the current gear is 2nd or 3rd, and the vehicle is turning without changing gears, when turning left, the vehicle experiences a centrifugal force to the right. The primary force is to the right, and the gear selector piston will shift to the right under the influence of this centrifugal force. See [link to relevant documentation]. Figure 5 To prevent the shifting piston from deviating, the first solenoid valve on the right side of the shifting piston is opened. The gas introduced based on the third opening of the first solenoid valve exerts a certain force on the shifting piston to the left. However, at this time, it is possible to push the shifting piston directly to the far left, for example, to the neutral position between reverse and first gear. Therefore, to prevent the shifting piston from being driven to the far left by force, the second solenoid valve on the left side of the shifting piston is opened. The gas introduced based on the fourth opening of the second solenoid valve exerts a certain force on the shifting piston to the right. Therefore, the difference between the force exerted by the gas introduced based on the third opening and the force exerted by the gas introduced based on the fourth opening is the second force. That is, the shifting piston is kept in the middle gear group position by the second force.

[0062] As an optional implementation, controlling the target solenoid valve according to its state includes: determining the target intake airflow rate corresponding to the opening degree of the target solenoid valve based on a preset correspondence between the solenoid valve opening degree and the intake airflow rate; and controlling the target solenoid valve according to the determined state of the target solenoid valve.

[0063] Specifically, the correspondence between the solenoid valve opening and the intake air velocity is preset. For example, a table showing the correspondence between the solenoid valve opening and the intake air velocity through the solenoid valve is used. When the solenoid valve opening is 1, the intake air velocity is p1; when the solenoid valve opening is 2, the intake air velocity is p2. When the solenoid valve is opened, air is introduced according to the corresponding intake air velocity.

[0064] As an optional implementation, the target solenoid valve is controlled according to its state to generate a second force acting on the gear selection piston. The method further includes closing the target solenoid valve after a preset time has elapsed since the turn was completed.

[0065] Specifically, after completing the turn, in order to ensure that the turn of the tractor and trailer is completely finished, after receiving the signal that the turn is complete, the control of the target solenoid valve is terminated and the target solenoid valve is closed after a preset time.

[0066] If the embodiment of this application detects that the vehicle is turning and the gear has not been updated, the AMT gear selection solenoid valve is controlled based on the turning signal to ensure the stability of the gear selection piston in the gear selection position. While ensuring turning stability, it can improve the reliability and comfort of the AMT.

[0077] If the current gear is any gear in the first edge gear group, and the direction of the first force is opposite to the first pointing direction, then based on the correspondence between the force and the solenoid valve state, the state of the target solenoid valve corresponding to the first force is determined as follows: the solenoid valve in the target direction of the gear selection piston is in the open state, and the opening degree of the solenoid valve is the first opening degree, wherein the target direction is the same as the direction of the centrifugal force, the first pointing direction is the direction from the middle gear group to the first edge gear group, the difference between the first solenoid valve force and the first edge force is the second force, the first solenoid valve force is the force of the gas introduced based on the first opening degree, the first edge force is the force of the first edge wall of the gear box on the gear selection piston, and the first edge gear group is attached to the first edge wall of the gear box;

[0079] If the current gear is in any gear of the intermediate gear group, then based on the correspondence between the force and the solenoid valve state, the state of the target solenoid valve corresponding to the first force is determined as follows: both the first and second solenoid valves at both ends of the gear selection piston are in the open state, and the opening degree of the first solenoid valve is the third opening degree, and the opening degree of the second solenoid valve is the fourth opening degree; wherein, the difference between the force of the gas introduced based on the third opening degree and the force of the gas introduced based on the fourth opening degree is the second force.
