[0040] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort belong to the scope of protection of the present application.

[0041] In related art, current hybrid vehicles are mainly distinguished by power systems. Japanese car companies represented by Toyota adopt power split hybrid systems, which are compact in structure and good in power economy, but are complex in control and high in technical barriers. German companies led by Volkswagen adopt P2 or P3 parallel hybrid systems, which have small changes to traditional powertrains. Currently, P2.5 parallel configuration is popular in China, such as Figure 2 as shown in the P2.5 configuration hybrid transmission schematic diagram, the motor is integrated into the double clutch transmission, and the motor is directly connected with the 2 and 4 gear teeth on the even shaft of the transmission through an idler wheel, as Figure 1The P2.5 parallel configuration is currently popular in China. In this configuration, the motor is integrated into the double-clutch transmission, and the motor is directly connected to the 2 and 4 gear teeth on the even shaft of the transmission through an idler. It can realize pure electric, hybrid and engine direct drive functions, and has the advantages of P2 and P3. It has advantages in the transition between oil and electricity and makes the economic operation area of the motor wider. In this configuration, the motor has two gears. During the 2-4 gear shifting process of the motor, the motor speed decreases and the torque increases. The gear shifting process is divided into three stages. First, the motor torque is zeroed to disconnect the 2 gear synchronizer. Second, in order to reach the target speed of the 4 gear, the motor speed needs to be controlled, and the motor needs to output negative torque to generate power. Third, when the motor reaches the target speed of the 4 gear, the 4 gear synchronizer is connected. As can be seen from the 2-4 gear shifting process of the motor, during the speed regulation process in the second stage, the motor needs to output negative torque to generate power. If the battery power is too high (98%, according to engineering experience) at this time, the battery is prohibited from charging or the allowable charging power is very small, the minimum torque available for the motor will be too small, which will cause the motor to be unable to regulate speed or the speed regulation time to be too long, the transmission cannot perform the motor gear shifting process, and the transmission will report a motor gear shifting timeout, the vehicle will directly enter the limp mode, and the vehicle driving function will be seriously affected.

[0042] To overcome the above problems, the application provides a vehicle upshift gear shifting control method, which aims to identify the request for motor upshift when the battery charging power is too high, and the power generated by the motor during the negative torque regulation process is used to provide the working power of the PTC, thereby avoiding the problem that the minimum torque available for the motor is too small due to the battery prohibiting charging or allowing very small charging power, which causes the motor to be unable to regulate speed or the speed regulation time to be too long.

[0043] Reference Figures 1 to 3 , Figure 1 is a step flow chart of a vehicle upshift gear shifting control method in an embodiment of the application, Figure 3 is a flow chart of a vehicle upshift gear shifting control method in an embodiment of the application; as shown in the figure, Figures 1 to 3 The method comprises steps S101 to S103.

[0044] Step S101: When a triggered gear upshift request is detected, acquire a plurality of working condition information associated with the gear upshift request, wherein the plurality of working condition information comprises: the chargeable power of the battery, the discharge power of the ceramic heater PTC on the vehicle and the current speed of the motor.

[0045] In the embodiment, during the vehicle operation, when the gear upshift operation from the second gear to the fourth gear is needed, the MCU (Moter Control Unit) can send a motor gear upshift request to the VCU (Vehicle Control Unit) according to the current driving speed, and the VCU receives the motor gear upshift request and saves it. In the embodiment, the motor gear upshift request and the vehicle operation parameter information during the vehicle operation can be obtained in real time. The vehicle operation parameter information includes current speed information corresponding to the current speed of the motor and current shift line parameter information corresponding to the target speed under different accelerator pedals. Different accelerator pedals correspond to different target speeds. When the VCU receives the request of the motor to upshift from the second gear to the fourth gear, the gear upshift operation can be performed only when the current speed of the motor meets the value of the target speed corresponding to the stepped accelerator pedal by judging the numerical relationship between the current speed of the motor and the target speed corresponding to the stepped accelerator pedal. The VCU collects various working condition information associated with the gear upshift request of the vehicle when detecting the triggered gear upshift request.

[0046] In a possible implementation, the various working condition information includes the chargeable power of the battery, the discharge power of the ceramic heater PTC on the vehicle, and the current speed of the motor.

[0047] In another possible implementation, the step of triggering the gear upshift when detecting the triggered gear upshift request includes steps S201-S202.

[0048] Step S201: obtaining current speed parameter information and current shift line parameter information;

[0049] In the embodiment, the vehicle operation parameter information includes current speed information corresponding to the current speed of the motor and current shift line parameter information corresponding to the target speed under different accelerator pedals. Different accelerator pedals correspond to different target speeds.

[0050] Step S202: matching the target speed of the motor according to the current shift line parameter information, and comparing it with the current speed of the motor;

[0051] In the embodiment, when the VCU receives the request of the motor to upshift from the second gear to the fourth gear, the gear upshift operation can be performed only when the current speed of the motor meets the value of the target speed corresponding to the stepped accelerator pedal by judging the numerical relationship between the current speed of the motor and the target speed corresponding to the stepped accelerator pedal.

[0052] Step S202: determining the available minimum torque of the motor according to the various working condition information.

[0053] In an embodiment, the VCU calculates and determines the available minimum torque of the motor according to the acquired working condition information

[0054] In an embodiment, the determination of the available minimum torque of the motor according to the working condition information comprises steps S301 to S303.

[0055] Step S301: Real-time acquisition of the battery available charging power parameter, the PTC discharging power parameter and the motor current actual speed parameter in the vehicle operating parameters

[0056] In the embodiment, the VCU acquires the working condition information such as the battery available charging power parameter, the PTC discharging power parameter and the motor current actual speed parameter in real time during the vehicle operation. The battery available charging power parameter is used to reflect the remaining capacity of the battery, which is defined as the ratio of the remaining capacity to the battery capacity in value. The PTC discharging power parameter refers to the rated working power of the ceramic heater. According to the engineering experience, the rated working power of the ceramic heater is 5KW. The motor current actual speed parameter is the actual speed of the motor under the current operating condition.

[0057] Step S302: Calculation of the available minimum torque of the motor according to the calculation formula of the minimum torque of the motor constructed by the battery available charging power parameter, the PTC discharging power parameter, the motor current speed parameter and the motor discharging efficiency parameter.

[0058] In the embodiment, the VCU obtains the available minimum torque of the motor through logical calculation of the real-time parameter data such as the battery available charging power parameter and the motor current actual speed parameter and the preset fixed parameter data such as the PTC discharging power parameter and the motor discharging efficiency parameter. The calculation formula of the available minimum torque of the motor is

[0059]

[0060] Step S103: When the calculated value of the available minimum torque of the motor is greater than the minimum torque threshold value, the electrical connection between the motor and the PTC is turned on, so that the power generated by the motor for speed regulation is used for the operation of the PTC.

[0061] In the embodiment, the available minimum torque of the motor is compared with the preset minimum torque threshold value of the motor. When the available minimum torque of the motor is greater than the minimum torque threshold value, the VCU sends a working request to the PCT, turns on the electrical connection part of the motor and the PTC, so that the PTC starts to work, and the power generation amount of the motor during the upshift speed regulation process is used for the work of the PTC to heat the circulating water. When the available charging power of the battery is too high, the power generation amount of the motor during the upshift speed regulation process in the configuration does not exceed 10kJ, and when the rated power of the PTC is 5kW, the upshift speed regulation time of the motor does not exceed 2s, and the temporary opening of the PTC does not affect the performance of the vehicle.

[0062] In another possible embodiment, when the available minimum torque of the motor is less than the minimum torque threshold value, the motor speed regulation mode is executed to drive the motor to complete the upshift.

[0063] In the embodiment, when the available minimum torque of the motor is less than the minimum torque threshold value, the available minimum torque of the motor at this time meets the condition of continuing to execute the upshift, and the motor speed regulation mode is executed to drive the motor to complete the upshift operation.

[0064] In a possible embodiment, the motor speed regulation mode driving the motor includes steps S401 to S402.

[0065] Step S401: Real-time acquisition of the rotating speed of the motor.

[0066] Step S402: When the rotating speed of the motor reaches the target rotating speed of the target gear, the gearbox is controlled to upshift, and the output shaft of the motor is controlled to close the synchronizer corresponding to the target gear.

[0067] In the embodiment, when it is determined that the vehicle needs to upshift, the upshift operation is executed, the torque of the motor shaft and the synchronizer is cleared, and there is no interaction torque between the motor shaft and the synchronizer, so that the motor shaft and the synchronizer can be smoothly separated. When the torque clearing is completed, the motor shaft and the synchronizer are controlled to be separated. When the rotating speed of the vehicle motor reaches the target rotating speed of the target gear, the gearbox needs to be controlled to upshift, and the output shaft of the motor needs to be controlled to close the synchronizer corresponding to the target gear, so that the motor is combined with the synchronizer of the target gear.

[0068] In another feasible implementation, during the process of the motor being connected to the PTC, the calculated value of the available minimum torque of the motor is updated based on real-time multi-condition information associated with the gear shift request. When the updated calculated value of the available minimum torque of the motor is less than the minimum torque threshold, the motor speed regulation mode is executed to drive the motor, disconnect the electrical connection between the motor and the PTC, and complete the gear shift.

[0069] In this embodiment, during the process of the motor and the PTC being connected, the motor continuously supplies power to the PTC to heat the circulating water, and updates the calculated minimum available torque value of the motor in real time based on various real-time operating condition information associated with the gear shift request. It continuously judges the relationship between the calculated minimum available torque value of the motor and the minimum available torque threshold of the motor. When the minimum torque calculated value is less than the minimum available torque threshold of the motor, the motor speed regulation mode is executed to drive the motor, and the electrical connection between the motor and the PTC is disconnected. The motor no longer supplies power to the PTC, and the vehicle completes the gear shift.

[0070] In another feasible implementation, the motor and the PTC are kept connected when the updated calculated minimum available torque of the motor is not less than the minimum torque threshold, until the updated calculated minimum available torque of the motor is less than the minimum torque threshold, at which point the connection between the motor and the PTC is disconnected.

[0071] In this embodiment, during the process of the motor being connected to the PTC, the motor continuously supplies power to the PTC to heat the circulating water. The motor's calculated minimum available torque is updated in real-time based on various operating condition information associated with the gear shift request. The relationship between the calculated minimum available torque and the minimum available torque threshold is continuously assessed. When the calculated minimum torque is not less than the minimum available torque threshold, the connection between the motor and the PTC is maintained, and the calculated minimum available torque is continuously updated until it falls below the minimum torque threshold, at which point the connection between the motor and the PTC is disconnected.

[0072] The motor is driven in speed control mode, and the electrical connection between the motor and the PTC is disconnected. The motor no longer supplies power to the PTC, and the vehicle completes the upshift.
