Description

Technical Field

[0001] The present disclosure relates to the field of vehicle control technology, and in particular to a vehicle driving mode control method, device, equipment, storage medium and vehicle. Background Art

[0002] With the rapid development of new energy technology, consumers are increasingly accepting new energy vehicles, and the sales of new energy vehicles are increasing. And with the stricter requirements for new energy points and engine emissions, OEMs, i.e. vehicle manufacturers, are gradually starting to use new energy technologies in passenger cars, pickup trucks, light trucks and other models, and hybrid vehicles and extended-range vehicles are gradually entering the market.

[0003] The emission of the engine must meet the emission requirements, so it is necessary to perform engine regeneration treatment, that is, combustion treatment of the emission particles. During parking regeneration or driving regeneration, the engine speed will be relatively high, especially for hybrid vehicles equipped with diesel engines, which can even reach about 3000rpm. At present, if the current engine is regenerating, but according to the hybrid mode management strategy of the vehicle controller, as the driver decelerates or drives with a small throttle, or stops, the vehicle's driving mode may switch to pure electric mode, and the mode will be frequently switched during driving, causing the engine to frequently enter regeneration, which is not conducive to the regeneration of the engine and the economy of the vehicle.

[0004] In the prior art, the timing of engine regeneration is not considered when switching modes. As driving conditions change, the vehicle driving mode may switch from hybrid mode to pure electric mode, or switch to engine shutdown mode. When the engine was regenerated in the previous cycle, the engine temperature has reached a certain value. However, if the engine is shut down at this time, the post-processing temperature will drop. After the engine is started again, additional fuel injection is required to increase the post-processing temperature and burn the exhaust particles. The existing driving mode control method has the problem that engine regeneration cannot be performed continuously, which will cause the engine to consume more fuel in order to heat up each time it is started and regenerated, which is not conducive to the economy of the vehicle. Summary of the invention

[0058] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0059] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0060] With the rapid development of new energy technology, consumers are increasingly accepting new energy vehicles, and the sales of new energy vehicles are increasing. And with the stricter requirements for new energy points and engine emissions, OEMs, i.e. vehicle manufacturers, are gradually starting to use new energy technologies in passenger cars, pickup trucks, light trucks and other models, and hybrid vehicles and extended-range vehicles are gradually entering the market.

[0061] The emission of the engine must meet the emission requirements, so it is necessary to perform engine regeneration treatment, that is, combustion treatment of the emission particles. During parking regeneration or driving regeneration, the engine speed will be relatively high, especially for hybrid vehicles equipped with diesel engines, which can even reach about 3000rpm. At present, if the current engine is regenerating, but according to the hybrid mode management strategy of the vehicle controller, as the driver decelerates or drives with a small throttle, or stops, the vehicle's driving mode may switch to pure electric mode, and the mode will be frequently switched during driving, causing the engine to frequently enter regeneration, which is not conducive to the regeneration of the engine and the economy of the vehicle.

[0062] In the prior art, the timing of engine regeneration is not considered when switching modes. As driving conditions change, the vehicle driving mode may switch from hybrid mode to pure electric mode, or switch to engine shutdown mode. When the engine was regenerated in the previous cycle, the engine temperature has reached a certain value. However, if the engine is shut down at this time, the post-processing temperature will drop. After the engine is started again, additional fuel injection is required to increase the post-processing temperature and burn the exhaust particles. The existing driving mode control method has the problem that engine regeneration cannot be performed continuously, which will cause the engine to consume more fuel in order to heat up each time it is started and regenerated, which is not conducive to the economy of the vehicle.

[0063] To address this problem, an embodiment of the present disclosure provides a vehicle driving mode control method, which is described below in conjunction with a specific embodiment.

[0064] Figure 1 This is a flow chart of the vehicle driving mode control method provided in the embodiment of the present disclosure. The method can be applied to the scenario of controlling the vehicle driving mode when the vehicle engine is currently in a regeneration state. It can be understood that the vehicle driving mode control method provided in the embodiment of the present disclosure can also be applied in other scenarios.

[0065] Below Figure 1 The vehicle driving mode control method shown in FIG. 1 is introduced, and the method includes the following steps:

[0066] S101. Acquire a current driving mode of a vehicle, where the current driving mode of the vehicle includes one of a hybrid power mode, an engine direct drive mode, a parking power generation mode, and a creeping power generation mode.

[0067] In this step, the vehicle terminal obtains the current driving mode of the vehicle, which includes one of a hybrid power mode, an engine direct drive mode, a parking power generation mode, and a creeping power generation mode. Optionally, the current driving mode of the vehicle may also include other driving modes, without limitation.

[0068] S102: Determine whether the engine of the vehicle is currently in a regeneration state.

[0069] In this step, the vehicle-mounted terminal determines whether the vehicle's engine is currently in a regeneration state. If so, S103 is executed, otherwise, the vehicle's engine continues to be monitored to determine whether it is currently in a regeneration state.

[0070] S103: If the engine of the vehicle is currently in a regeneration state, obtain the current driving condition of the vehicle.

[0071] If it is determined that the vehicle's engine is currently in a regeneration state, the vehicle's current driving condition is obtained. Optionally, the current driving condition may be that the current motor driving force is greater than or equal to the vehicle's driving force, the throttle opening is greater than zero, the battery state of charge is greater than or equal to a preset threshold, the battery state of charge is fully charged, the throttle opening is zero, the vehicle is in a coasting state, or the current vehicle speed is less than a preset vehicle speed threshold, the current vehicle speed does not meet the vehicle speed condition of the engine direct drive mode, or the current battery state of charge does not meet the charge state condition of the engine direct drive mode, or other driving conditions, which are not specifically limited here.

[0072] S104: Based on the current driving mode and the current driving condition, the driving mode of the vehicle is controlled so that the engine continues to maintain a regeneration state.

[0073] After obtaining the current driving condition of the vehicle, the vehicle terminal can control the driving mode of the vehicle based on the current driving mode and the current driving condition, so that the engine continues to maintain the regeneration state. Specifically, when the vehicle driving mode is in the hybrid mode, engine direct drive mode, parking power generation mode, creeping power generation mode and other engine start-up states, and the engine is currently in the regeneration state, the current driving mode is maintained during driving, and the mode is switched according to the specific driving condition. When switching the driving mode, the engine regeneration state can be taken into account, so that the engine can be continuously regenerated, avoiding the engine from frequently entering regeneration, reducing the fuel consumption during the engine regeneration process, and improving the economy of the whole vehicle.

[0074] In some embodiments, S104 may include but is not limited to S1041, S1042, S1043:

[0075] S1041. Determine whether the vehicle is a single-motor hybrid vehicle.

[0076] In this step, the vehicle-mounted terminal determines whether the vehicle is a single-motor hybrid vehicle, which is essentially determining whether the vehicle is a single-motor hybrid vehicle or a dual-motor hybrid vehicle.

[0077] S1042: For a single-motor hybrid vehicle, in combination with a current driving mode and a current driving condition, a control strategy corresponding to the single-motor hybrid vehicle is used to control the driving mode of the vehicle.

[0078] In this step, if the vehicle is a single-motor hybrid vehicle, the vehicle-mounted terminal uses a control strategy corresponding to a single-motor hybrid vehicle to control the vehicle's driving mode in combination with the current driving mode and the current driving conditions.

[0079] S1043. For a dual-motor hybrid vehicle, in combination with a current driving mode and a current driving condition, a control strategy corresponding to the dual-motor hybrid vehicle is used to control the driving mode of the vehicle.

[0080] In this step, if the vehicle is a dual-motor hybrid vehicle, the vehicle-mounted terminal uses a control strategy corresponding to the dual-motor hybrid vehicle to control the vehicle's driving mode in combination with the current driving mode and the current driving condition.

[0081] In some embodiments, the method further includes: when it is detected that the driver triggers an operation of forcing the pure electric mode, stopping engine regeneration and controlling the vehicle to enter the pure electric mode.

[0082] In this embodiment, if it is detected that the driver has triggered an operation to force the pure electric mode, engine regeneration is stopped and the vehicle is controlled to enter the pure electric mode. This is based on the driver's intention. Even if the engine is in a regenerating state at this time, engine regeneration is stopped and the vehicle is controlled to enter the pure electric mode to improve the driving experience.

[0083] The disclosed embodiment determines whether the vehicle's engine is currently in a regeneration state by obtaining the vehicle's current driving mode, which includes one of a hybrid power mode, an engine direct drive mode, a parking power generation mode, and a creeping power generation mode. If the vehicle's engine is currently in a regeneration state, the vehicle's current driving condition is obtained, and based on the current driving mode and the current driving condition, the vehicle's driving mode is controlled so that the engine continues to remain in a regeneration state. Compared with the prior art, if the vehicle's engine is currently in a regeneration state, the disclosed embodiment obtains the vehicle's current driving condition, and then controls the vehicle's driving mode based on the current driving mode and the current driving condition so that the engine continues to remain in a regeneration state, so that the engine can be continuously regenerated, avoiding the engine from frequently entering regeneration, reducing fuel consumption during the engine regeneration process, and improving the economy of the entire vehicle.

[0084] Figure 2 A flow chart of a vehicle driving mode control method provided by another embodiment of the present disclosure is as follows: Figure 2 As shown, the method includes the following steps:

[0085] S201. Acquire a current driving mode of a vehicle, where the current driving mode of the vehicle includes one of a hybrid power mode, an engine direct drive mode, a parking power generation mode, and a creeping power generation mode.

[0086] Specifically, the implementation process and principle of S201 and S101 are the same, and will not be repeated here.

[0087] S202: Determine whether the engine of the vehicle is currently in a regeneration state.

[0088] Specifically, the implementation process and principle of S202 and S102 are the same, and will not be repeated here.

[0089] S203: If the engine of the vehicle is currently in a regeneration state, obtain the current driving condition of the vehicle.

[0090] Specifically, the implementation process and principle of S203 and S103 are the same, and will not be repeated here.

[0091] S204: Determine whether the vehicle is a single-motor hybrid vehicle.

[0092] In this step, the vehicle-mounted terminal determines whether the vehicle is a single-motor hybrid vehicle, which is essentially determining whether the vehicle is a single-motor hybrid vehicle or a dual-motor hybrid vehicle.

[0093] S205. For a single-motor hybrid vehicle, if the current driving mode is a hybrid power mode, the current driving condition is that the current motor driving force is greater than or equal to the vehicle driving force, and the throttle opening is greater than zero, then the vehicle is controlled to maintain the current driving mode as a hybrid power mode and maintain the engine regeneration state.

[0094] For a single-motor hybrid vehicle, if the current driving mode is hybrid mode, the current motor driving force can meet the vehicle driving force required by the driver, that is, the current driving condition is that the current motor driving force is greater than or equal to the vehicle driving force, and the vehicle is currently in a driving condition where the driver steps on the accelerator (the accelerator opening is greater than 0) and has power, then the vehicle is controlled to maintain the current driving mode in hybrid mode. At this time, the engine can be kept in a continuous regeneration state, or it can generate electricity according to the power battery charging requirements.

[0095] S206: If the current driving mode is the hybrid mode, and the current driving condition is that the battery state of charge is greater than or equal to a preset threshold, and the throttle opening is greater than zero, then control the vehicle to maintain the current driving mode as the hybrid mode and maintain the engine regeneration state.

[0096] For a single-motor hybrid vehicle, if the current driving mode is hybrid mode, the current battery state of charge (SOC) has reached the threshold for exiting hybrid mode, that is, the battery state of charge is greater than or equal to the preset threshold, and the vehicle is currently in a driving condition where the driver steps on the accelerator (the throttle opening is greater than 0) and has power, then the vehicle is controlled to maintain the current driving mode in hybrid mode. At this time, the engine can be kept in a continuous regeneration state, or it can generate electricity according to the power battery charging demand.

[0097] S207. If the current driving mode is the hybrid power mode, the current driving condition is that the battery state of charge is fully charged and the throttle opening is greater than zero, then the high-voltage power consumption is detected. When the high-voltage power consumption is less than the preset power threshold, the vehicle is controlled to switch the current driving mode to the engine direct drive mode to maintain the engine regeneration state.

[0098] For a single-motor hybrid vehicle, if the current driving mode is hybrid mode, and the current driving condition is that the SOC has reached the limit state of 100%, that is, the battery state of charge is fully charged and the throttle opening is greater than zero, then the high-voltage power consumption is detected. When the high-voltage power consumption is less than the preset power threshold, the vehicle is controlled to switch the current driving mode from hybrid mode to engine direct drive mode to maintain the engine regeneration state. Optionally, the preset power threshold can be 0.5kw or other values, without specific limitation.

[0099] Optionally, the power consumption of high-voltage electrical appliances such as an electric heater (Positive Temperature Coefficient, PTC), an electric compressor, and a direct current converter (Direct Current-Direct Current converter, DCDC) may be added together to obtain the magnitude of the high-voltage power consumption.

[0100] S208. If the current driving mode is the hybrid mode, the current driving condition is that the throttle opening is zero and the whole vehicle is in a coasting state, the vehicle is controlled to enter a coasting energy recovery state, and the battery charging power is increased based on the battery charging demand. When the ratio of the input shaft speed to the transmission ratio is less than or equal to the sum of the output shaft speed and the preset offset, the vehicle is controlled to disconnect the clutch between the engine and the motor to maintain the engine regeneration state.

[0101] For a single-motor hybrid vehicle, if the current driving mode is hybrid mode, the current driver does not step on the accelerator, that is, the throttle opening is zero, and the vehicle is in a coasting state, the vehicle is controlled to enter a coasting energy recovery state. Increasing the battery charging power based on the battery charging demand can increase the vehicle charging rate. The maximum charging power cannot exceed the upper limit of the power battery charging power and the lower limit of the generator torque. However, as the vehicle coasts or brakes, the vehicle speed will gradually decrease. For a non-decoupled single-motor hybrid vehicle, as the vehicle speed gets lower and lower, if the engine speed is not decoupled in time at this time, the engine will be stopped, causing the engine regeneration to stop. Therefore, when the ratio of the input shaft speed to the transmission ratio is less than or equal to the sum of the output shaft speed and the preset offset, the on-board terminal controls the vehicle to disconnect the clutch between the engine and the motor to maintain the engine regeneration state. Specifically, when InPutSpd / Ratio≤OutPutSpd+offset, where InPutSpd represents the input shaft speed, Ratio represents the transmission ratio, OutPutSpd represents the output shaft speed, and offset represents the preset offset, at this time, the clutch between the engine and the motor is disconnected to protect the engine's transmission, so that the engine continues to maintain the regenerative state, and the hybrid coupler of the motor enters the braking energy recovery state to generate electricity for the battery.

[0102] S209. For a single-motor hybrid vehicle, if the current driving mode is the engine direct drive mode, and the current driving condition is that the current vehicle speed does not meet the vehicle speed condition of the engine direct drive mode or the current battery state of charge does not meet the charge state condition of the engine direct drive mode, then the vehicle is controlled to switch the current driving mode to the hybrid power mode and maintain the engine regeneration state.

[0103] For a single-motor hybrid vehicle, if the current driving mode is the engine direct drive mode, the engine direct drive mode is generally used at high speeds, at which time the engine's output power just meets the high-speed driving requirements. If the vehicle speed, SOC and other conditions do not meet the engine direct drive mode and the driving mode needs to be switched, the vehicle is controlled to switch the current driving mode from the engine direct drive mode to the hybrid power mode, thereby maintaining the engine drive and maintaining the engine regeneration state.

[0104] S210. If the current driving mode is the creeping power generation mode and the current driving condition is that the current vehicle speed is less than a preset vehicle speed threshold, the vehicle is controlled to disconnect the clutch between the engine and the motor, the engine is maintained in a regenerative state, and the charging power of the battery is increased based on the charging demand of the battery.

[0105] If the current driving mode is the creeping power generation mode, for a single-motor hybrid vehicle, the vehicle's driving force to maintain the creeping speed depends on the engine, and the engine also needs to continue to maintain a certain power generation power to keep the power battery charged. If the current driving condition is that the vehicle speed is less than the preset speed threshold, the engine speed cannot be maintained and may stall. At this time, it is necessary to disconnect the clutch between the engine and the motor, maintain the engine regeneration state, and increase the battery charging power based on the battery charging demand.

[0106] S211. If the current driving mode is the parking power generation mode and the current driving condition is that the driver is detected to have engaged a gear, the vehicle is controlled to temporarily stop engine high speed regeneration or the vehicle is controlled to continue engine regeneration based on the idle speed.

[0107] If the current driving mode is the parking power generation mode, when it is detected that the driver has engaged a gear, if the engine continues to regenerate at a high speed, the vehicle will rush out in an instant, endangering the driver's safety. Therefore, it is necessary to control the vehicle to temporarily stop the high-speed regeneration of the engine or control the vehicle to continue the engine regeneration based on the idle speed.

[0108] Compared with the prior art, the technical solution provided by the embodiments of the present disclosure has the following advantages:

[0109] The disclosed embodiment determines whether the vehicle's engine is currently in a regeneration state by obtaining the vehicle's current driving mode, which includes one of a hybrid power mode, an engine direct drive mode, a parking power generation mode, and a creeping power generation mode. Further, if the vehicle's engine is currently in a regeneration state, the vehicle's current driving condition is obtained to determine whether the vehicle is a single-motor hybrid vehicle. Furthermore, for a single-motor hybrid vehicle, the vehicle's driving mode is controlled by a control strategy corresponding to the single-motor hybrid vehicle in combination with the current driving mode and the current driving condition, so that the single-motor hybrid vehicle can consider the engine regeneration timing when switching the driving mode, and can enable the engine to regenerate continuously, avoiding the engine from frequently entering regeneration, reducing the fuel consumption of the engine regeneration process, and improving the economy of the whole vehicle. Through the above method, it can not only meet the requirement that the engine can be regenerated quickly, but also improve the charging efficiency and charging rate of the whole vehicle, and can avoid the problem of increased fuel consumption caused by frequent switching of driving modes, thereby improving the fuel saving rate of the whole vehicle.

[0110] Figure 3 A flow chart of a vehicle driving mode control method provided by another embodiment of the present disclosure is as follows: Figure 3 As shown, the method includes the following steps:

[0111] S301. Acquire a current driving mode of a vehicle, where the current driving mode of the vehicle includes one of a hybrid power mode, an engine direct drive mode, a parking power generation mode, and a creeping power generation mode.

[0112] Specifically, the implementation process and principle of S301 and S101 are the same, and will not be repeated here.

[0113] S302: Determine whether the engine of the vehicle is currently in a regeneration state.

[0114] Specifically, the implementation process and principle of S302 and S102 are the same, and will not be repeated here.

[0115] S303: If the engine of the vehicle is currently in a regeneration state, obtain the current driving condition of the vehicle.

[0116] Specifically, the implementation process and principle of S303 and S103 are the same, and will not be repeated here.

[0117] S304: Determine whether the vehicle is a single-motor hybrid vehicle.

[0118] Specifically, the implementation process and principle of S304 and S204 are the same, and will not be repeated here.

[0119] S305. For a dual-motor hybrid vehicle, if the current driving mode is the hybrid power mode, the current driving condition is that the current motor driving force is greater than or equal to the vehicle driving force, and the throttle opening is greater than zero, then the vehicle is controlled to maintain the current driving mode as the hybrid power mode and maintain the engine regeneration state.

[0120] For a dual-motor hybrid vehicle, under the current driving mode and current driving conditions, the control strategy is the same as that of a single-motor hybrid vehicle and will not be repeated here.

[0121] S306: If the current driving mode is the hybrid mode, and the current driving condition is that the battery state of charge is greater than or equal to a preset threshold, and the throttle opening is greater than zero, then control the vehicle to maintain the current driving mode as the hybrid mode and maintain the engine regeneration state.

[0122] For a dual-motor hybrid vehicle, under the current driving mode and current driving conditions, the control strategy is the same as that of a single-motor hybrid vehicle and will not be repeated here.

[0123] S307. If the current driving mode is the hybrid power mode, the current driving condition is that the battery state of charge is fully charged and the throttle opening is greater than zero, then the high-voltage power consumption is detected. When the high-voltage power consumption is less than the preset power threshold, the vehicle is controlled to switch the current driving mode to the engine direct drive mode to maintain the engine regeneration state.

[0124] For a dual-motor hybrid vehicle, under the current driving mode and current driving conditions, the control strategy is the same as that of a single-motor hybrid vehicle and will not be repeated here.

[0125] S308. If the current driving mode is the hybrid mode, the current driving condition is that the throttle opening is zero and the vehicle is in a coasting state, the vehicle is controlled to enter a coasting energy recovery state, and the battery charging power is increased based on the battery charging demand to maintain the engine regeneration state.

[0126] For dual-motor hybrid vehicles, if the current driving mode is hybrid mode, the current driver does not step on the accelerator, that is, the accelerator opening is zero, and the vehicle is in a coasting state, the vehicle is controlled to enter the coasting energy recovery state, and the battery charging power is increased based on the battery charging demand, which can increase the vehicle charging rate and continue to maintain the engine regeneration state. Since the engine of the dual-motor hybrid vehicle is decoupled, it is not necessary to decouple the engine speed according to the vehicle speed, that is, it is not necessary to control the vehicle to disconnect the clutch between the engine and the motor.

[0127] S309. If the current driving mode is the engine direct drive mode, and the current driving condition is that the current vehicle speed does not meet the vehicle speed condition of the engine direct drive mode or the current battery state of charge does not meet the charge state condition of the engine direct drive mode, then control the vehicle to switch the current driving mode to the hybrid power mode and maintain the engine regeneration state.

[0128] For a dual-motor hybrid vehicle, under the current driving mode and current driving conditions, the control strategy is the same as that of a single-motor hybrid vehicle and will not be repeated here.

[0129] S310: If the current driving mode is the creeping power generation mode and the current driving condition is that the current vehicle speed is less than a preset vehicle speed threshold, the engine regeneration state is maintained and the charging power of the battery is increased based on the charging demand of the battery.

[0130] For a dual-motor hybrid vehicle, if the current driving mode is the creeping power generation mode and the current driving condition is that the current vehicle speed is less than the preset vehicle speed threshold, the engine regeneration state is maintained and the battery charging power is increased based on the battery charging demand. Since the engine of the dual-motor hybrid vehicle is decoupled, it is not necessary to decouple the engine speed according to the vehicle speed, that is, it is not necessary to control the vehicle to disconnect the clutch between the engine and the motor.
