[0027] Embodiment one

[0028] Figure 1 is a flowchart of a gear adjustment method in the embodiment one of the present application, and the present embodiment can be applied to the case of adjusting the gear of a vehicle. It should be noted that, Figure 2 is a schematic diagram of a power system in the embodiment one of the present application, wherein 101 is an engine, 102 is a power motor, 201 is a main clutch, 202 is a current gear clutch, 203 is a target gear clutch, 302 is a current gear, 303 is a target gear, 401 is a transmission input shaft, 402 is a current gear clutch output shaft, i.e. a current gear input shaft, 403 is a target gear clutch output shaft, i.e. a target gear input shaft, and 404 is a transmission output shaft. During the driving process of the vehicle, when one clutch is engaged and transmits power, the other clutch is separated and does not transmit power, but the target gear is already engaged. When the upshift adjustment is performed, the current clutch is gradually separated, and the target clutch is gradually engaged, so as to ensure that the torque of the output shaft of the transmission does not fluctuate, and the power is not interrupted.

[0029] The gear adjustment method can be executed by the gear adjustment device in this embodiment of the invention. This device can be implemented in software and / or hardware, such as... Figure 1 As shown, the method specifically includes the following steps:

[0030] S110: Obtain the current gear ratio, current transmission output shaft torque, target gear ratio, and current gear status of the current vehicle.

[0031] The current gear ratio is the gear ratio of the final drive corresponding to the current gear in the vehicle. The current transmission output shaft torque can be determined by the driver's needs. The target gear ratio is the gear ratio of the final drive corresponding to the target gear in the vehicle. During power upshifting, the input shaft torque increases rapidly, and the gear state can be divided into four states, which can be represented as follows: the first state is the current gear clutch engagement state, the second state is the current gear clutch slipping state, the third state is the alternating engagement state of the current gear clutch and the target gear clutch, and the fourth state is the target gear clutch engagement state.

[0032] Specifically, the current gear ratio, current transmission output shaft torque, target gear ratio, and current gear status of the current vehicle can be obtained by the vehicle controller in real time.

[0033] S120 determines the torque transmission capability of the target gear based on the current gear ratio of the current vehicle, the current output shaft torque of the transmission, the target gear ratio, and the current gear status.

[0034] Among them, the torque transmission capability of the target gear is the torque transmission capability of the clutch of the target gear.

[0035] Specifically, the method for determining the torque transmission capability of the target gear based on the current gear ratio, current transmission output shaft torque, target gear ratio, and current gear status can be as follows: Determine the current gear status; first determine the torque transmission capability of the clutch of the current gear based on the current gear ratio, current transmission output shaft torque, and the current gear status corresponding to the current gear; then determine the final torque transmission capability of the target gear based on the current gear status corresponding to the target gear, the torque transmission capability of the clutch of the current gear, the current transmission output shaft torque, and the target gear ratio.

[0036] S130 adjusts the current gear of the vehicle based on the torque transmission capability of the target gear.

[0037] Specifically, adjusting the current vehicle gear based on the torque transmission capability of the target gear can be done by adjusting the vehicle gear to the target gear based on the torque transmission capability of the target gear.

[0038] Optionally, the torque transmission capability of the target gear is determined based on the current gear ratio of the current vehicle, the current output shaft torque of the transmission, the target gear ratio, and the current gear status, including:

[0039] The torque transmission capability of the current gear is determined based on the current gear ratio, the current output shaft torque of the transmission, and the current gear status.

[0040] The torque transmission capability of the target gear is determined based on the torque transmission capability of the current gear, the current output shaft torque of the transmission, the current gear status, and the target gear ratio.

[0041] The torque transmission capability of the current gear is the torque transmission capability of the clutch in the current gear.

[0042] Specifically, the method for determining the torque transmission capability of the current gear based on the current gear ratio, the current transmission output shaft torque, and the current gear state can be as follows: If the current gear state is a state associated with the current gear, such as the current gear clutch engagement state, the current gear clutch slipping state, or the current gear clutch and the target gear clutch alternating engagement state, the torque transmission capability of the current gear corresponding to each current gear state is calculated sequentially based on the current gear ratio, the current transmission output shaft torque, and the current gear state.

[0043] Specifically, the method for determining the transmission torque capacity of the target gear based on the transmission torque capacity of the current gear, the current transmission output shaft torque, the current gear state, and the target gear ratio can be as follows: If the current gear state is associated with the target gear, for example, if the current gear state is an alternating engagement state of the current gear clutch and the target gear clutch, or an engagement state of the target gear clutch, the final transmission torque capacity of the target gear in the current gear state can be determined based on the transmission torque capacity of the current gear, the current transmission output shaft torque, the current gear state, and the target gear ratio.

[0044] Optionally, the torque transmission capability of the current gear can be determined based on the current gear ratio, the current transmission output shaft torque, and the current gear status, including:

[0045] When the current gear state is the first state, the transmission input shaft torque corresponding to the current gear state is determined based on the current gear ratio and the current transmission output shaft torque;

[0046] The transmission input shaft torque corresponding to the current gear state is determined as the transmission torque capability of the current gear corresponding to the first state;

[0047] When the current gear state is the second state, the torque transmission capability of the current gear corresponding to the first state is determined as the torque transmission capability of the current gear corresponding to the second state.

[0048] When the current gear is in the third state, the torque transmission capability of the current gear corresponding to the second state is adjusted according to the set rules, and the adjusted torque transmission capability of the current gear corresponding to the second state is determined as the torque transmission capability of the current gear corresponding to the third state.

[0049] The first state can be the current gear clutch engagement state, the second state can be the current gear clutch slipping state, and the third state can be the alternating engagement state of the current gear clutch and the target gear clutch. The set rule can be a preset rule for adjusting the torque transmission capability of the current gear; for example, the set rule could be a preset slope, where the torque transmission capability of the current gear decreases according to the preset slope.

[0050] Specifically, when the current gear state is the first state, the method for determining the transmission input shaft torque corresponding to the current gear state based on the current gear ratio and the current transmission output shaft torque can be as follows: When the vehicle controller obtains that the current gear state is the first state, it calculates the transmission input shaft torque corresponding to the first state based on the current gear ratio and the current transmission output shaft torque, and then controls the drive motor and engine to output the transmission input shaft torque corresponding to the first state. For example, the calculation method for the transmission input shaft torque corresponding to the first state can be: Transmission input shaft torque corresponding to the first state = Current transmission output shaft torque / Current gear ratio.

[0051] Specifically, the method for determining the transmission input shaft torque corresponding to the current gear state as the transmission torque capability of the current gear corresponding to the first state can be as follows: the vehicle controller can send a determination command to the transmission controller, causing the transmission controller to determine the transmission input shaft torque corresponding to the first state as the transmission torque capability of the current gear corresponding to the first state based on the determination command.

[0052] Specifically, when the current gear state is the second state, the method to determine the transmission torque capability of the current gear corresponding to the first state as the transmission torque capability of the current gear corresponding to the second state can be as follows: when the current gear state is the second state, the transmission torque capability of the current gear corresponding to the first state is determined as the transmission torque capability of the current gear corresponding to the second state. The vehicle controller and the transmission controller send a determination command, and the transmission controller outputs the transmission torque capability of the current gear. That is, in the second state, the transmission torque capability of the current gear corresponding to the second state = the current transmission output shaft torque / the current gear ratio.

[0053] Specifically, when the current gear state is the third state, the method for adjusting the transmission torque capability of the current gear corresponding to the second state according to a preset rule, and determining the adjusted transmission torque capability of the current gear corresponding to the second state as the transmission torque capability of the current gear corresponding to the third state, can be as follows: When the current gear state is the third state, the transmission torque capability of the current gear corresponding to the second state is adjusted according to a preset rule, and the adjusted transmission torque capability of the current gear corresponding to the second state is determined in real time as the transmission torque capability of the current gear corresponding to the third state. For example, if the preset rule is a preset slope, the transmission torque capability of the current gear is determined to decrease by 500 N·m per second, and the reduced transmission torque capability of the current gear is determined as the transmission torque capability of the current gear corresponding to the third state.

[0054] By determining the transmission input shaft torque corresponding to the current gear state as the transmission torque capability of the current gear in the first state; when the current gear state is the second state, the transmission torque capability of the current gear corresponding to the first state is determined as the transmission torque capability of the current gear corresponding to the second state; when the current gear state is the third state, the transmission torque capability of the current gear corresponding to the second state is adjusted according to the set rules, and the adjusted transmission torque capability of the current gear corresponding to the second state is determined as the transmission torque capability of the current gear corresponding to the third state, it is possible to ensure that the transmission torque capability of the current gear smoothly transitions in each gear state, thereby ensuring uninterrupted power.

[0055] Optionally, the transmission torque capacity of the target gear is determined based on the transmission torque capacity of the current gear, the current transmission output shaft torque, the current gear status, and the target gear ratio, including:

[0056] When the torque transmission capability of the current gear corresponding to the third state is a preset value, the current gear state is determined to be the fourth state.

[0057] When the current gear state is the fourth state, the transmission input shaft torque corresponding to the current gear state is determined based on the target gear ratio and the current transmission output shaft torque;

[0058] The transmission input shaft torque corresponding to the current gear position is determined as the transmission torque capability of the target gear.

[0059] The preset value can be 0. The fourth state can be the target gear clutch engagement state.

[0060] Specifically, when the torque transmission capability of the current gear corresponding to the third state is a preset value, the method to determine the current gear state as the fourth state can be as follows: if the torque transmission capability of the current gear corresponding to the third state has been adjusted to the preset value according to preset rules, and the clutch of the current gear is fully disengaged, then the current gear state is determined to have entered the fourth state. Another method to determine the current gear state as the fourth state is that the vehicle controller can directly obtain the current gear state of the vehicle.

[0061] Specifically, when the current gear state is the fourth state, the method for determining the transmission input shaft torque corresponding to the current gear state based on the target gear ratio and the current transmission output shaft torque can be as follows: When the current gear state is the fourth state, obtain the target gear ratio and the current transmission output shaft torque, and calculate the transmission input shaft torque corresponding to the fourth state based on the target gear ratio and the current transmission output shaft torque. For example, the calculation method for the transmission input shaft torque corresponding to the fourth state can be: Transmission input shaft torque corresponding to the fourth state = Current transmission output shaft torque / Target gear ratio.

[0062] Specifically, the method to determine the transmission input shaft torque corresponding to the current gear state as the transmission torque capability of the target gear can be as follows: the vehicle controller sends a determination command to the transmission controller, instructing the transmission controller to control the transmission input shaft torque corresponding to the fourth state to be the transmission torque capability of the target gear.

[0063] When the torque transmission capability of the current gear corresponding to the third state is a preset value, the current gear state is determined to be the fourth state. When the current gear state is the fourth state, the transmission input shaft torque corresponding to the current gear state is determined according to the target gear ratio and the current transmission output shaft torque. Determining the transmission input shaft torque corresponding to the current gear state as the torque transmission capability of the target gear ensures that the target clutch gradually engages in the third and fourth states, and the gear is smoothly adjusted according to the torque transmission capability of the target gear.

[0064] Optionally, when the current gear state is the third state, the torque transmission capability of the current gear corresponding to the second state is adjusted according to a set rule, and the adjusted torque transmission capability of the current gear corresponding to the second state is determined as the torque transmission capability of the current gear corresponding to the third state, including:

[0065] Adjust the transmission input shaft torque corresponding to the current gear state according to the torque transmission capability of the current gear corresponding to the second state, and obtain the first speed difference between the active and driven parts of the clutch of the current gear during the adjustment process;

[0066] When the current gear is in the third state, if the duration of the first speed difference between the driving and driven parts of the clutch in the current gear is greater than the time threshold, the torque transmission capability of the current gear corresponding to the second state is adjusted according to the set rules, and the adjusted torque transmission capability of the current gear corresponding to the second state is determined as the torque transmission capability of the current gear corresponding to the third state.

[0067] The first speed difference and time threshold can be set according to actual needs.

[0068] It should be noted that the clutch's torque transmission capability can be controlled by adjusting the engagement pressure of the driving and driven parts of the clutch. When the driving and driven parts of the clutch are engaged, if the torque transmission capability is higher than or equal to the actual torque transmitted, the clutch remains engaged, and the transmitted torque is the actual torque. When the torque transmission capability is lower than the actual torque transmitted, the driving part of the clutch begins to slip, and the speed of the driving part gradually exceeds that of the driven part, and the transmitted torque is the clutch's torque transmission capability. When the driving and driven parts of the clutch are disengaged, the clutch's torque transmission capability is 0, and the torque transmitted by the clutch is also 0. When the driving and driven parts of the clutch are slipping, if the torque transmission capability is lower than the actual torque transmitted, the driving part of the clutch continues to slip, and the speeds of both the driving and driven parts continue to increase, and the transmitted torque is the clutch's torque transmission capability. If the torque transmission capability is higher than the actual torque transmitted, the speeds of both the driving and driven parts continue to decrease until they decrease to 0, and the transmitted torque is the clutch's torque transmission capability.

[0069] Specifically, the method of adjusting the transmission input shaft torque corresponding to the current gear state based on the transmission torque capability of the current gear state in the second state, and obtaining the first speed difference between the active and driven parts of the clutch in the current gear state during the adjustment process, can be as follows: In the second state, the clutch in the current gear state begins to slip, the transmission input shaft torque corresponding to the current gear state is adjusted, and the first speed difference between the active and driven parts of the clutch in the current gear state is continuously obtained during the adjustment process.

[0070] Specifically, when the current gear state is the third state, if the duration of the first speed difference between the active and driven parts of the current gear clutch is greater than a time threshold, the transmission torque capability of the current gear corresponding to the second state is adjusted according to the set rules, and the adjusted transmission torque capability of the current gear corresponding to the second state is determined as the transmission torque capability of the current gear corresponding to the third state. The method is as follows: the vehicle controller controls the transmission input shaft torque output by the power motor and engine to be higher than the preset threshold of the transmission torque capability of the current gear, so that the duration of the first speed difference between the active and driven parts of the current gear clutch is greater than the time threshold, that is, a fixed first speed difference is maintained. When the current gear state is the third state, the transmission torque capability of the current gear corresponding to the second state is adjusted according to the set rules, and the adjusted transmission torque capability of the current gear corresponding to the second state is determined as the transmission torque capability of the current gear corresponding to the third state.

[0071] Optionally, when the current gear state is the fourth state, the transmission input shaft torque corresponding to the current gear state is determined based on the target gear ratio and the current transmission output shaft torque, including:

[0072] The transmission torque capability of the target gear corresponding to the third state is determined based on the transmission torque capability of the current gear corresponding to the third state, the current gear ratio, the current transmission output shaft torque, and the target gear ratio.

[0073] The transmission input shaft torque corresponding to the current gear state is adjusted based on the transmission torque capability of the current gear corresponding to the third state and the transmission torque capability of the target gear corresponding to the third state, and the second speed difference between the active and driven parts of the clutch in the current gear state is obtained during the adjustment process.

[0074] When the current gear is in the fourth state, if the duration of the second speed difference between the active and driven parts of the current gear clutch is greater than the time threshold, the transmission input shaft torque corresponding to the current gear state is determined based on the target gear ratio and the current transmission output shaft torque.

[0075] The second speed difference and time threshold can be set according to actual needs and can be consistent with the first speed difference.

[0076] Specifically, the method for determining the transmission torque capability of the target gear corresponding to the third state based on the transmission torque capability of the current gear, the current gear ratio, the current transmission output shaft torque, and the target gear ratio can be as follows: Obtain the transmission torque capability of the current gear, the current gear ratio, the current transmission output shaft torque, and the target gear ratio corresponding to the third state; then calculate the transmission torque capability of the target gear corresponding to the third state based on these parameters. For example, the formula for calculating the transmission torque capability of the target gear corresponding to the third state can be: Transmission torque capability of the target gear corresponding to the third state = (Current transmission output shaft torque - Transmission torque capability of the current gear * Current gear ratio) / Target gear ratio.

[0077] Specifically, the method of adjusting the transmission input shaft torque corresponding to the current gear state based on the transmission torque capability of the current gear corresponding to the third state and the transmission torque capability of the target gear corresponding to the third state, and obtaining the second speed difference between the active and driven parts of the clutch in the current gear state during the adjustment process, can be as follows: In the third state, the transmission input shaft torque corresponding to the current gear state is adjusted in real time based on the transmission torque capability of the current gear corresponding to the third state and the transmission torque capability of the target gear corresponding to the third state, and the second speed difference between the active and driven parts of the clutch in the current gear state is obtained during the adjustment process.

[0078] Specifically, when the current gear state is the fourth state, if the duration of the second speed difference between the driving and driven parts of the current gear clutch is greater than a time threshold, the transmission input shaft torque corresponding to the current gear state can be determined based on the target gear ratio and the current transmission output shaft torque as follows: the vehicle controller controls the transmission input shaft torque output by the power motor and engine to be higher than the sum of the transmission torque capability of the current gear, the transmission torque capability of the target gear corresponding to the third state, and the preset threshold, so that the duration of the second speed difference between the driving and driven parts of the current gear clutch is greater than the time threshold, i.e., maintaining a fixed second speed difference. When the current gear state is the fourth state, the target gear ratio and the current transmission output shaft torque are obtained, and the transmission input shaft torque corresponding to the current gear state is determined based on the target gear ratio and the current transmission output shaft torque. For example, the transmission input shaft torque corresponding to the fourth state can be calculated as: transmission input shaft torque corresponding to the fourth state = current transmission output shaft torque / target gear ratio.

[0079] The technical solution of this embodiment obtains the current gear ratio, current transmission output shaft torque, target gear ratio, and current gear status of the current vehicle; determines the transmission torque capability of the target gear based on the current gear ratio, current transmission output shaft torque, target gear ratio, and current gear status; and adjusts the gear of the current vehicle according to the transmission torque capability of the target gear. This solves the problem that the transmission is prone to power interruption during upshifting, which leads to a decrease in vehicle driving performance. It can achieve uninterrupted power transmission and smooth, shock-free transmission during upshifting, effectively improving vehicle driving performance.
