Description

Technical Field

[0001] The present invention relates to the field of automobile technology, and in particular to a hybrid vehicle shift control method, device, electronic equipment, and medium. Background Art

[0002] In the existing technology, hybrid vehicles are usually developed based on multiple driving modes, and the hybrid architecture driving mode is one of the multiple driving modes. The hybrid architecture usually adopts a planetary gear solution. At this time, the hybrid architecture driving modes using the planetary gear solution include engine direct drive mode, pure electric (Electric Vehicle, referred to as EV) mode and continuously variable transmission (Continuously Variable Transmission, referred to as CVT) mode. During normal driving, different modes can be switched to meet the driver's power and comfort requirements. The preset steps of the shifting process are: gear disengagement - speed synchronization - gear engagement - torque recovery.

[0003] However, hybrid drive systems using planetary gears exhibit poor shifting smoothness during rapid acceleration and deceleration, with prolonged gear shift synchronization times, making them prone to jerking and gear sticking. For example, when a vehicle accelerates rapidly, the shaft speed increases rapidly; then decelerates rapidly, the speed drops rapidly, and a downshift is requested. The shaft speed drops rapidly with the speed, but the engine speed cannot drop quickly enough to reach the target speed, leading to a prolonged synchronization time and gear sticking. Furthermore, the engine's load torque is greater than the shifting torque, preventing gear engagement. Consequently, existing hybrid drive systems using planetary gears experience a high probability of gear sticking after a shift failure. Summary of the Invention

[0041] The main implementation principles, specific implementation methods and corresponding beneficial effects of the technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0042] Example

[0043] Please refer to Figure 1, an embodiment of the present application provides a method for controlling gear shifting of a hybrid vehicle, the method comprising:

[0044] S101. During driving of a hybrid vehicle, obtaining a first comparison result between an actual motor speed of the hybrid vehicle and a theoretical motor speed, obtaining a second comparison result between an actual vehicle speed of the hybrid vehicle and a theoretical vehicle speed, and obtaining a third comparison result between an actual engine speed of the hybrid vehicle and a theoretical engine speed;

[0045] S102: Determine whether the first comparison result, the second comparison result, and the third comparison result meet a gear initialization condition;

[0046] S103: When the first comparison result, the second comparison result, and the third comparison result satisfy the gear initialization condition, adjusting the gear of the hybrid vehicle from the current gear to the initial gear.

[0047] The hybrid vehicle shift control method described in the embodiments of this specification is typically applied to an on-board terminal or server. The on-board terminal can be, for example, the hybrid vehicle's head unit or controller, and the server can be a cloud server or a local server. The server can be, for example, a laptop, desktop computer, tablet computer, all-in-one computer, or other electronic device. The following specifically uses an on-board terminal as an example.

[0048] Among them, in step S101, during the driving process of the hybrid vehicle, the motor speed signal can be collected in real time through the motor sensor, and the real-time collected motor speed signal can be transmitted to the vehicle control unit (VECU) of the hybrid vehicle, so that the on-board terminal of the hybrid vehicle can obtain the actual motor speed in real time; then, the actual motor speed is compared with the theoretical motor speed to obtain a first comparison result.

[0049] Accordingly, while the hybrid vehicle is driving, a vehicle speed sensor can collect a vehicle speed signal in real time and transmit the collected speed signal to the hybrid vehicle's VECU, allowing the hybrid vehicle's onboard terminal to obtain the vehicle's actual speed in real time. The actual vehicle speed is then compared with the theoretical vehicle speed to obtain a second comparison result. Furthermore, while the hybrid vehicle is driving, an engine speed sensor can collect an engine speed signal in real time and transmit the collected speed signal to the hybrid vehicle's VECU, allowing the hybrid vehicle's onboard terminal to obtain the engine's actual speed in real time. The actual engine speed is then compared with the theoretical engine speed to obtain a third comparison result.

[0050] Specifically, when obtaining the first comparison result, the motor speed sensor may first collect motor speed signals over a recent period of time to determine whether the hybrid vehicle's motor speed is in an increasing or decreasing phase. If the motor speed signals collected over the recent period of time determine that the motor speed is in an increasing phase, the actual motor speed of the hybrid vehicle is compared to determine whether it is less than the sum of the theoretical motor speed and the corrected motor speed, thereby obtaining a first motor speed comparison result, wherein the first comparison result includes the first motor speed comparison result. If the motor speed signals collected over a period of time determine that the motor speed is in a decreasing phase, the actual motor speed of the hybrid vehicle is compared to determine whether it is less than the theoretical motor speed, thereby obtaining a second motor speed comparison result, wherein the first comparison result includes the second motor speed comparison result.

[0051] Among them, the most recent period of time refers to a period of time adjacent to the current time. The length of the most recent period of time can be set according to actual needs. For example, the most recent period of time can be half a minute (min), 1 minute and 30 seconds (s) before the current time. This manual does not impose any specific restrictions.

[0052] Accordingly, when obtaining the second comparison result, the vehicle speed sensor may first collect vehicle speed signals over a recent period of time to determine whether the hybrid vehicle's speed is in an increasing or decreasing phase. If the vehicle speed is determined to be increasing based on the collected vehicle speed signals over a recent period of time, the actual vehicle speed of the hybrid vehicle is compared to determine whether it is less than the sum of the theoretical vehicle speed and the corrected vehicle speed, thereby obtaining a first vehicle speed comparison result, wherein the second comparison result includes the first vehicle speed comparison result. If the vehicle speed is determined to be decreasing based on the collected vehicle speed signals over a recent period of time, the actual vehicle speed of the hybrid vehicle is compared to determine whether it is less than the theoretical vehicle speed, thereby obtaining a second vehicle speed comparison result, wherein the second comparison result includes the second vehicle speed comparison result.

[0053] Furthermore, when obtaining the third comparison result, the engine speed sensor may first collect engine speed signals over a recent period of time to determine whether the hybrid vehicle's engine speed is in an increasing or decreasing phase. If the engine speed signals collected over the recent period of time determine that the engine speed is in an increasing phase, the actual engine speed of the hybrid vehicle is compared to determine whether it is less than the sum of the theoretical engine speed and the corrected engine speed, thereby obtaining a first engine speed comparison result. The third comparison result includes the first engine speed comparison result. If the engine speed signals collected over the recent period of time determine that the engine speed is in a decreasing phase, the actual engine speed of the hybrid vehicle is compared to determine whether it is less than the theoretical engine speed, thereby obtaining a second engine speed comparison result. The third comparison result includes the second engine speed comparison result.

[0054] In the embodiments of this specification, the theoretical motor speed, the theoretical vehicle speed, and the theoretical engine speed can all be set according to actual needs, can be calibrated, or can be set manually or by the equipment itself, and this specification does not impose any specific restrictions.

[0055] After the first comparison result, the second comparison result, and the third comparison result are obtained, step S102 is executed.

[0056] In step S102, it is determined whether the first comparison result, the second comparison result and the third comparison result meet the gear initialization condition; when it is determined that the first comparison result, the second comparison result and the third comparison result all meet the gear initialization condition, step S103 is executed; otherwise, step S103 is prohibited from being executed.

[0057] Specifically, if the motor speed is in the rising stage, and the first comparison result indicates that the actual motor speed is less than the sum of the motor theoretical speed and the motor corrected speed, then the first comparison result is determined to meet the gear initialization condition; and, if the motor speed is in the falling stage, and the first comparison result indicates that the actual motor speed is less than the motor theoretical speed, then the first comparison result is determined to meet the gear initialization condition; except for the above two motor speed conditions, the first comparison result is determined to not meet the gear initialization condition.

[0058] Among them, if the vehicle speed is in the rising stage, and the second comparison result indicates that the actual vehicle speed is less than the sum of the vehicle theoretical speed and the vehicle corrected speed, then the second comparison result is determined to meet the gear initialization condition; and if the vehicle speed is in the falling stage, and the second comparison result indicates that the actual vehicle speed is less than the vehicle theoretical speed, then the second comparison result is determined to meet the gear initialization condition; except for the above two vehicle speed conditions, the second comparison result is determined to not meet the gear initialization condition.

[0059] Also, if the engine speed is in an increasing stage, and the third comparison result indicates that the actual engine speed is less than the sum of the engine theoretical speed and the engine corrected speed, then the third comparison result is determined to meet the gear initialization condition; and, if the engine speed is in a decreasing stage, and the third comparison result indicates that the actual engine speed is less than the engine theoretical speed, then the third comparison result is determined to meet the gear initialization condition; except for the above two engine speed conditions, the third comparison result is determined to not meet the gear initialization condition.

[0060] In this way, when the first comparison result satisfies the gear initialization condition, the second comparison result satisfies the gear initialization condition, and the third comparison result also satisfies the gear initialization condition, step S103 is executed.

[0061] For example, taking the hybrid vehicle A as an example, during the driving process of the hybrid vehicle A, the motor speed signal is collected in real time through the motor speed sensor. The actual motor speed obtained in real time is represented by N1. N1 is compared with the theoretical motor speed N. Whether to activate the motor reset function is judged by the motor speed, including: when the motor speed is in the rising stage, it is judged whether N1 is less than the sum of N and the motor correction speed N2, and the first motor speed comparison result is obtained. Among them, if the first motor speed comparison result indicates that N1 < (N + N2), the motor reset function is activated; otherwise, the activation of the motor reset function is prohibited; and when the motor speed is in the falling stage, it is judged whether N1 is less than N, and the second motor speed comparison result is obtained. Among them, if the second motor speed comparison result indicates that N1 < N, the motor reset function is activated; otherwise, the activation of the motor reset function is prohibited.

[0062] Correspondingly, the vehicle speed signal is collected in real time through the vehicle speed sensor. The actual vehicle speed obtained in real time is represented by V1. V1 is compared with the theoretical vehicle speed V. Whether to activate the vehicle speed reset function is judged by the vehicle speed, including: when the vehicle speed is in the rising stage, it is judged whether V1 is less than the sum of V and the vehicle correction speed V2, and the first vehicle speed comparison result is obtained. Among them, if the first vehicle speed comparison result indicates that V1 < (V + V2), the test reset function is activated; otherwise, the activation of the vehicle speed reset function is prohibited; and when the vehicle speed is in the falling stage, it is judged whether V1 is less than V, and the second vehicle speed comparison result is obtained. Among them, if the second vehicle speed comparison result indicates that V1 < V, the vehicle speed reset function is activated; otherwise, the activation of the vehicle speed reset function is prohibited.

[0063] And, the engine speed signal is collected in real time through the engine speed sensor. The actual engine speed obtained in real time is represented by M1. M1 is compared with the theoretical engine speed M. Whether to activate the engine reset function is judged by the engine speed, including: when the engine speed is in the rising stage, it is judged whether M1 is less than the sum of M and the engine correction speed M2, and the first engine speed comparison result is obtained. Among them, if the first engine speed comparison result indicates that M1 < (M + M2), the engine reset function is activated; otherwise, the activation of the engine reset function is prohibited; and when the engine speed is in the falling stage, it is judged whether M1 is less than M, and the second engine speed comparison result is obtained. Among them, if the second engine speed comparison result indicates that M1 < M, the engine reset function is activated; otherwise, the activation of the engine reset function is prohibited. <0,000,137>Thus, after the motor reset function, the vehicle speed reset function, and the engine reset function are all activated, it is determined that the first comparison result, the second comparison result, and the third comparison result all meet the gear initial conditions, and then step S103 is executed; otherwise, the execution of step S103 is prohibited.

[0065] When it is determined that the first comparison result, the second comparison result, and the third comparison result all meet the gear initial condition, step S103 is executed.

[0066] In step S103, if it is determined that the first comparison result, the second comparison result, and the third comparison result all meet the gear initialization condition, the previously calibrated or stored initial gear can be obtained, and a gear initialization signal is sent to the automatic transmission control unit (Transmission-Control-Unit, TCU) of the hybrid vehicle through the VECU, so that the TCU adjusts the gear of the hybrid vehicle from the current gear to the initial gear according to the gear initialization signal.

[0067] In one embodiment, to further improve the accuracy of gear adjustment, when the first comparison result, the second comparison result, and the third comparison result meet the gear initialization condition, it is further determined whether the hybrid vehicle is in a high-pressure state and whether the gear mode of the hybrid vehicle is in a continuously variable transmission (CVT) mode. If it is detected that the hybrid vehicle is in a high-pressure state and the gear mode of the hybrid vehicle is in the CVT mode, the gear of the hybrid vehicle is adjusted from the current gear to the initial gear.

[0068] In actual application, Figure 2 As shown, a logic diagram for gear initialization enable judgment is used for gear initialization function judgment, including the following steps: A1, judging that the current gear signal is a CVT mode gear, such as CVT_1, CVT_2, etc.; A2, judging the high-voltage state of the vehicle; A3, used to calculate the motor speed enabling condition, according to the comparison between the motor end speed N1 and the motor theoretical speed N, and then judging whether to activate the motor reset function according to the motor speed: when the motor speed increases, the motor end speed N1 is less than (theoretical motor speed N+corrected motor speed N2), and the motor reset function is activated; when the motor speed decreases, the motor end speed N1 is less than the theoretical motor speed N, and the motor reset function is activated; A4, used to calculate the vehicle speed enabling condition, according to the comparison between the vehicle speed V1 and the theoretical vehicle speed V The vehicle speed is used to determine whether the speed reset function is activated: when the vehicle speed increases, the speed V1 is less than (theoretical speed V + speed correction V2), the speed reset function is activated; when the vehicle speed decreases, the speed V1 is less than the theoretical speed V, the speed reset function is activated. A5 is used to calculate the engine speed enabling condition. Based on the comparison between the engine speed M1 and the theoretical engine speed M, the engine reset function is activated based on the engine speed: when the engine speed increases, the engine speed M1 is less than (theoretical speed M + engine correction speed M2), the engine reset function is activated; when the speed decreases, the engine speed M1 is less than the theoretical speed M, the engine reset function is activated. A6 indicates the gear initialization function is activated, with 1 indicating active and 0 indicating inactive. All of the above conditions are in an AND relationship.

[0069] Furthermore, when the current gear signal is a CVT mode gear, the vehicle is in a high-voltage state, the motor reset function is activated, the vehicle speed reset function is activated, the engine reset function is activated, and the gear initialization function is activated, step A7 is executed to execute the gear initialization function to adjust the gear of the hybrid vehicle from the current gear to the initial gear; otherwise, execution of the gear initialization function is prohibited.

[0070] In this way, the VECU performs gear initialization judgment, and makes a comprehensive judgment based on the current vehicle information, the motor speed, the vehicle speed, the engine speed, the vehicle high voltage and the CVT mode. It can accurately judge whether the hybrid vehicle is currently in a gear stuck situation after a gear shift failure. When it is judged that the hybrid vehicle is currently in a gear stuck situation after a gear shift failure, the TCU performs a gear initialization action, and rotates the gear shift mechanism back to the initial gear position through the gear shift motor to reduce the probability of gear sticking after a gear shift failure, and also reduce the probability of insufficient power due to gear sticking, thereby improving the driving performance of the hybrid vehicle and providing the user with a better driving experience.

[0071] The above one or at least one technical solution in the embodiments of the present application has at least the following technical effects:

[0072] Based on the above technical solution, during the driving process of the hybrid vehicle, a first comparison result of the actual motor speed of the hybrid vehicle and the theoretical motor speed is obtained, a second comparison result of the actual vehicle speed of the hybrid vehicle and the theoretical vehicle speed is obtained, and a third comparison result of the actual engine speed of the hybrid vehicle and the theoretical engine speed is obtained; and when it is determined that the first comparison result, the second comparison result and the third comparison result meet the gear initialization condition, the gear of the hybrid vehicle is adjusted from the current gear to the initial gear. It can be seen that by judging the first comparison result, the second comparison result and the third comparison result meet the gear initialization condition, the gear of the hybrid vehicle is adjusted from the current gear to the initial gear. The result of the first gear shift and the result of the third comparison are compared to see whether they meet the gear initialization condition. If they meet the condition, it can be confirmed that the hybrid vehicle has a gear stuck after a gear shift failure, thereby activating the gear initialization function to adjust the gear of the hybrid vehicle from the current gear to the initial gear to solve the problem of insufficient power caused by the gear sticking. In this way, the above technical solution can effectively reduce the probability of gear sticking after a gear shift failure when using a planetary gear solution, and can also reduce the probability of insufficient power caused by gear sticking, thereby improving the driving performance of the hybrid vehicle and providing users with a better driving experience.
