For example, when running in environments such as long-term uphill climbing or high temperatures, it can cause the motor to overheat. Repeated high temperatures in a short period of time not only affect the lifespan of the motor, but also affect the driving safety of the driver. Summary of the Invention

[0004] This invention provides a method, device, electronic device, and storage medium for controlling gear shifting in an automotive transmission, in order to solve the problem that traditional gear shifting based on speed can cause motor overheating in some scenarios.

If the operating conditions of the first vehicle do not meet the first condition, the second shifting method is used for shifting. The second shifting method is to control the motor of the first vehicle to upshift when the current speed of the first speed is greater than the third speed, and to control the motor of the first vehicle to downshift when the current speed of the first speed is less than the fourth speed. The first speed is greater than the third speed; the fourth speed is equal to the third speed minus the preset speed.

[0006] According to another aspect of the present invention, a vehicle transmission shift control device is provided, the device comprising: The operating environment determination module is used to determine the operating environment of the first vehicle; The first condition determination module is used to perform a first shifting method when shifting gears if the operating environment of the first vehicle meets the first condition. The first condition is that when the first vehicle is operating in the operating environment, the temperature of the motor of the first vehicle is greater than a preset temperature within a preset time period. The first shifting method is to control the motor of the first vehicle to upshift when the current speed of the first rotational speed is greater than the first rotational speed, and to control the motor of the first vehicle to downshift when the current speed of the first rotational speed is less than the second rotational speed. The second rotational speed is equal to the first rotational speed minus the preset rotational speed. The second condition judgment module is used to shift gears using a second shifting method if the operating conditions of the first vehicle do not meet the first condition. The second shifting method is to control the motor of the first vehicle to shift up when the current speed of the first speed is greater than the third speed, and to control the motor of the first vehicle to shift down when the current speed of the first speed is less than the fourth speed. The first speed is greater than the third speed, and the fourth speed is equal to the third speed minus the preset speed.

[0010] The technical solution of this invention determines the operating environment of a first vehicle. If the operating environment of the first vehicle meets a first condition, a first shifting method is used during gear shifting. The first condition is that when the first vehicle is operating in this environment, the temperature of the first vehicle's motor is greater than a preset temperature within a preset time period.

Detailed Implementation

[0014] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0015] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0016] In one embodiment, Figure 1 This is a flowchart of a vehicle transmission shift control method provided in an embodiment of the present invention. This embodiment is applicable to situations where vehicle transmissions are shifting gears. The method can be executed by a vehicle transmission shift control device, which can be implemented in hardware and / or software. This vehicle transmission shift control device can be configured in an electronic device with data processing capabilities. Figure 1 As shown, the method includes: S110. Determine the operating environment of the first vehicle.

[0017] The first vehicle can be any vehicle requiring gearbox shift control. The first vehicle can be a new energy vehicle or a hybrid vehicle. The type of vehicle can be an engineering vehicle, a private vehicle, etc., and this application does not impose any restrictions on this.

[0018] The operating environment of the first vehicle can be the environmental information surrounding the vehicle at the current moment of operation, as well as the vehicle's own parameters. The operating environment includes, but is not limited to, throttle opening, motor temperature, motor speed, motor torque, current vehicle gradient, vehicle load, longitudinal acceleration, wind speed, and ambient temperature and humidity. The operating environment of the first vehicle can be determined through the transmission controller (TCU), vehicle controller (VCU), and acceleration sensors. Among these, sensors such as the acceleration sensor can be integrated into the vehicle controller.

[0019] S120. If the operating environment of the first vehicle meets the first condition, then the first shifting method is used for shifting when shifting gears; the first condition is that when the first vehicle is running in the operating environment, the temperature of the first vehicle motor is greater than the preset temperature within a preset time period; the first shifting method is that when the current speed of the first speed is greater than the first speed, the motor of the first vehicle is controlled to shift up; when the current speed of the first speed is less than the second speed, the motor of the first vehicle is controlled to shift down; the second speed is equal to the first speed minus the preset speed.

[0020] During the operation of the first vehicle, this application divides its operating environment into two types: one is an operating environment that meets the first condition, in which continuous operation of the first vehicle will cause the temperature of the first vehicle motor to rise above a preset temperature within a preset time period, i.e., the motor will overheat; the other is an operating environment that does not meet the first condition, in which continuous operation of the first vehicle will cause the temperature of the first vehicle motor to stabilize below the preset temperature. Therefore, different shifting methods are used in the two different operating environments. When the operating environment meets the first condition, it is not possible to prevent the first vehicle temperature from rising above the preset temperature or from dropping the temperature below the preset temperature in a timely manner after it has risen above the preset temperature. This application uses the first shifting method for automatic shifting, that is, when the current speed of the first vehicle is greater than the first speed, the motor of the first vehicle is controlled to shift up; when the current speed of the first speed is less than the second speed, the motor of the first vehicle is controlled to shift down.

[0021] In this method, the first speed is higher than the third speed. This allows for a further increase in the speed required for upshifting when the first condition is met, based on the principle that higher motor speeds result in less energy loss and less heat generation. This reduces the problem of rapid temperature rise after upshifting. Similarly, the downshifting speed will also be higher than that of the second shifting method.

[0022] For example, the engine shifts up when the current speed is greater than 9200 rpm and downshifts when the current speed is less than 9200-400=8800 rpm. Here, the first speed is 9200 rpm; the preset speed is 4000 rpm.

[0023] Optionally, the first condition is that the first slope of the first vehicle is greater than the preset slope and the first weight of the first vehicle is greater than the preset weight. Accordingly, the operating environment of the first vehicle is determined, including: Determine the first gradient and the first weight of the first vehicle. The first gradient is the gradient of the road surface on which the first vehicle is traveling at the current moment, and the first weight is the sum of the vehicle weight and the load weight of the first vehicle at the current moment.

[0024] Further refining the operating environment that meets the first condition, we can see that the heavy-load hill-climbing scenario belongs to this operating environment.

[0025] Therefore, it is necessary to determine the first slope and the first weight of the first vehicle. Since it was clarified earlier that the vehicle controller integrates an acceleration sensor, the first slope and the first weight can be estimated by using the recursive least squares method based on the acceleration sensor.

[0026] The corresponding determination of whether the operating environment of the first vehicle meets the first condition can be made by determining whether the first slope of the first vehicle is greater than the preset slope and whether the first weight of the first vehicle is greater than the preset weight.

[0027] When the first gradient of the first vehicle is greater than the preset gradient and the first weight of the first vehicle is greater than the preset weight, it can be determined that the operating environment of the first vehicle meets the first condition.

[0028] Optionally, in addition to specific values, the first weight can be divided into three states: light load, standard load, and heavy load. The corresponding first slope can also be divided into uphill, plain, and downhill. The three states are used to determine whether the operating environment meets the first condition.

[0029] Optionally, the first condition is that the first temperature of the motor of the first vehicle is greater than the preset temperature; Accordingly, the operating environment of the first vehicle is determined, including: Determine the first temperature of the motor of the first vehicle at the current moment.

[0030] In addition to heavy-load uphill conditions, there may also be problems such as hot weather, which directly lead to an increase in motor temperature. At this time, the first temperature of the first vehicle motor is determined. When the first temperature is greater than the preset temperature, it can be determined that the operating environment meets the first condition.

[0031] Optionally, the first condition is that the first longitudinal acceleration of the first vehicle is less than the preset acceleration and the first throttle opening of the first vehicle is greater than the preset opening; Accordingly, the operating environment of the first vehicle is determined, including: Determine the longitudinal acceleration of the first vehicle at the current moment to obtain the first longitudinal acceleration; Determine the throttle opening of the first vehicle at the current moment to obtain the first longitudinal acceleration.

[0032] In addition to the first two scenarios, there is also a third scenario related to longitudinal acceleration and throttle opening. When the longitudinal acceleration is collected by an acceleration sensor, and the first longitudinal acceleration is less than the preset acceleration and the first throttle opening of the first vehicle is greater than the preset opening, it can be determined that the operating environment of the first vehicle meets the first condition.

[0033] S130. If the operating conditions of the first vehicle do not meet the first condition, the second shifting method shall be used for shifting when shifting gears. The second shifting method is that when the current speed of the first speed is greater than the third speed, the motor of the first vehicle shall be controlled to shift up; when the current speed of the first speed is less than the fourth speed, the motor of the first vehicle shall be controlled to shift down. The first speed is greater than the third speed; the fourth speed is equal to the third speed minus the preset speed.

[0034] If the operating conditions of the first vehicle do not meet the first condition, it can be determined that the motor temperature of the first vehicle will not exceed the preset temperature. In this case, the shifting can be performed according to the original second shifting method.

[0035] The technical solution provided by this invention determines the operating environment of a first vehicle. If the operating environment of the first vehicle meets a first condition, a first shifting method is used during gear shifting. The first condition is that when the first vehicle is operating in this environment, the temperature of the first vehicle's motor is greater than a preset temperature within a preset time period. The first shifting method involves controlling the first vehicle's motor to upshift when the current speed of the first rotational speed is greater than the first rotational speed, and controlling the first vehicle's motor to downshift when the current speed of the first rotational speed is less than the second rotational speed. The second rotational speed is equal to the first rotational speed minus a preset rotational speed. If the operating conditions of the first vehicle do not meet the first condition, a second shifting method is used during gear shifting. The second shifting method involves controlling the first vehicle's motor to upshift when the current speed of the first rotational speed is greater than the third rotational speed, and controlling the first vehicle's motor to downshift when the current speed of the first rotational speed is less than the fourth rotational speed. The first rotational speed is greater than the third rotational speed, and the fourth rotational speed is equal to the third rotational speed minus a preset rotational speed. This avoids the problem of motor overheating during the operation of the first vehicle, ensuring the driver's safety and preventing a reduction in the vehicle's service life.

[0036] In one embodiment, Figure 2 This is a flowchart of another vehicle transmission shift control method provided by an embodiment of the present invention. The relationship between this embodiment and the above embodiments is that, when the first vehicle includes a motor and an engine, the steps of controlling the motor of the first vehicle to shift up are further explained. Figure 2 As shown, the method includes: S210. Determine the first power of the motor of the first vehicle and the shift power of the engine; the first power is the motor power at the current moment.

[0037] S220, based on the first power and the engine shift power, shifts the first vehicle up a gear.

[0038] When the first vehicle includes a motor and an engine, in order to avoid the vehicle jerking due to sudden power changes during gear shifting, a first power and an engine shifting power are determined. During gear shifting, the power of the engine and motor are adjusted by the first power and the engine shifting power to achieve upshifting of the first vehicle.

[0039] Optionally, based on the first power and the engine shift power, the first vehicle is upshifted, including: The engine power of the first vehicle is increased from the first power to the engine shift power, and the motor torque is simultaneously reduced to zero before upshifting. Adjust the engine power from the engine shift power to the first power, and control the motor power to increase from zero to the first power.

[0040] The upshifting process for the first vehicle is the same as the downshifting process, so only the upshifting process for the first vehicle will be described. When upshifting or downshifting, the vehicle controller (VCU) first sends the target gear to the transmission controller (TCU), and then the VCU calculates the current power of the drive motor, which is the first power, and calculates the engine shifting power.

[0041] The vehicle controller controls the engine power to increase from the first power to the engine shift power, while simultaneously controlling the drive motor torque to zero. The transmission controller (TCU) controls disengagement. The vehicle controller calculates the target speed of the drive motor and sends it to the motor controller to adjust the drive motor to the target speed. The transmission controller (TCU) controls shifting and adjusts the engine power from the engine shift power to the first power, while controlling the motor power to increase from zero to the first power.

[0042] By adopting the technical solution of this application, the first power of the motor of the first vehicle and the shifting power of the engine are determined; the first power is the motor power at the current moment; based on the first power and the shifting power of the engine, the first vehicle is shifted up to ensure stable driving of the vehicle during the shifting process.

The first condition is that when the first vehicle is operating in the operating environment, the temperature of the motor of the first vehicle is greater than a preset temperature within a preset time period. The first shifting method is to control the motor of the first vehicle to shift up when the current speed of the first speed is greater than the first speed, and to control the motor of the first vehicle to shift down when the current speed of the first speed is less than the second speed. The second speed is equal to the first speed minus the preset speed. The second condition discrimination module 330 is used to shift gears using a second shifting method if the operating conditions of the first vehicle do not meet the first condition. The second shifting method is to control the motor of the first vehicle to shift up when the current speed of the first speed is greater than the third speed, and to control the motor of the first vehicle to shift down when the current speed of the first speed is less than the fourth speed. The first speed is greater than the third speed, and the fourth speed is equal to the third speed minus the preset speed.

[0044] In one embodiment, optionally, the first condition is that the first slope of the first vehicle is greater than a preset slope and the first weight of the first vehicle is greater than a preset weight. Accordingly, the operating environment of the first vehicle is determined, including: Determine the first gradient and the first weight of the first vehicle. The first gradient is the gradient of the road surface on which the first vehicle is traveling at the current moment, and the first weight is the sum of the vehicle weight and the load weight of the first vehicle at the current moment.

[0045] In one embodiment, optionally, the first condition is that the first temperature of the first vehicle motor is greater than a preset temperature; Accordingly, the operating environment of the first vehicle is determined, including: Determine the first temperature of the motor of the first vehicle at the current moment.

[0046] In one embodiment, optionally, the first condition is that the first longitudinal acceleration of the first vehicle is less than a preset acceleration and the first throttle opening of the first vehicle is greater than a preset opening; Accordingly, the operating environment of the first vehicle is determined, including: Determine the longitudinal acceleration of the first vehicle at the current moment to obtain the first longitudinal acceleration; Determine the throttle opening of the first vehicle at the current moment to obtain the first longitudinal acceleration.
