[0002] With the addition of restrictions on particulate matter emissions in the National VI emission regulations, and the emission restrictions of National VI Phase B are 10 times stricter than those of National VI Phase A, based on considerations of fuel consumption, emissions, etc., major OEMs are moving towards pure electric vehicles and hybrid vehicles. Due to the frequent start and stop of the engine in hybrid vehicles, especially strong hybrid vehicles, the start and stop are more frequent, and the amount of particulate matter emitted from their exhaust is greater than that of traditional fuel vehicles.

[0016] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0019] Embodiment 1 See also Figure 1 , shown is a service station-based strong hybrid vehicle GPF regeneration control method in a first embodiment of the present invention, the method includes steps S10 to S13.

[0020] Step S10, when a GPF service station regeneration request flag sent by the engine is received, it is determined whether the vehicle speed, gear position and parking brake status of the vehicle meet preset conditions.

[0021] Among them, the HCU (hybrid controller) receives the GPF service station regeneration request signal sent by the EMS (engine controller). Specifically, it determines whether the vehicle speed is 0, whether the gear is in P gear or N gear, whether the handbrake is pulled, and whether the brake pedal is not stepped on. The purpose of judging these conditions is to ensure that the vehicle is stationary and the driver has no intention of driving. If any of the above conditions is not met during the judgment and regeneration process, the GPF service station regeneration will not be responded.

[0022] Step S11, when it is determined that the vehicle speed, gear position and parking brake status of the vehicle meet the preset conditions, it is determined whether the engine, generator and battery pack of the vehicle meet the preset conditions.

[0023] Among them, it is judged whether the parts involved in the regeneration of the GPF service station are normal, such as the engine is not faulty, the P1 motor is not faulty, the battery pack is not faulty, and the battery pack cell temperature and discharge power are greater than the threshold (the standard for the design of this threshold is to meet the charging requirements during the regeneration process of the GPF service station. The engine has a load, and the exhaust temperature can rise smoothly, so that the regeneration effect is better). If any of the above conditions are not met during the judgment conditions and the regeneration process, the GPF service station regeneration will not be responded.

[0024] Step S12, when it is determined that the engine, generator and battery pack of the vehicle meet the preset conditions, it is determined whether the GPF service station regeneration request meets the preset conditions.

[0025] Among them, it is judged whether this service station regeneration state is the first time in this power-on cycle. If not, no response is given. It is judged whether the HCU response GPF service station regeneration time is greater than the threshold (the standard for this threshold design is about 30% longer than the normal service station regeneration time, which can be set according to the actual vehicle test). The purpose is to prevent EMS and diagnostic instrument from being triggered multiple times by mistake or EMS from not requesting to exit the GPF service station regeneration state, resulting in waste of manpower and material resources and affecting the safety of the entire vehicle. Protect the safety of the driver and the entire vehicle to the greatest extent.

[0026] Step S13, when it is determined that the GPF service station regeneration request meets a preset condition, the vehicle is controlled to enter a GPF service station regeneration state to regenerate the GPF of the vehicle.

[0027] Specifically, when all the above conditions are met, the HCU enters the GPF service station regeneration state, starts the engine, sends the target speed to the engine controller to control the engine to enter the speed control mode; starts the generator, sends the target torque to the generator, and controls the generator to enter the torque control mode.

[0028] In summary, the present invention determines whether the vehicle speed, gear position and parking brake state meet the preset conditions when receiving the GPF service station regeneration request flag sent by the engine; when it is determined that the vehicle speed, gear position and parking brake state meet the preset conditions, it determines whether the vehicle engine, generator and battery pack meet the preset conditions; when it is determined that the vehicle engine, generator and battery pack meet the preset conditions, it determines whether the GPF service station regeneration request meets the preset conditions; when it is determined that the GPF service station regeneration request meets the preset conditions, it controls the vehicle to enter the GPF service station regeneration state to regenerate the vehicle's GPF, and performs a comprehensive vehicle inspection before regeneration control to ensure that the regeneration conditions are met. The problem of poor effect of GPF regeneration control of strong hybrid vehicles based on service stations in the prior art is solved.

[0029] Embodiment 2 This embodiment also proposes a strong hybrid vehicle GPF regeneration control method based on a service station. The difference between the strong hybrid vehicle GPF regeneration control method based on a service station in this embodiment and the strong hybrid vehicle GPF regeneration control method based on a service station in the first embodiment is that: The step of sending the target speed to the engine controller to control the engine to enter the speed control mode includes: The target speed is sent to the engine controller at a preset slope to control the engine to enter the speed control mode.

[0030] Among them, when all the above conditions are met, the HCU enters the GPF service station regeneration state, starts the engine, and outputs the speed control mode to the EMS, and sends the target speed to the EMS according to a smaller slope (this slope should not be too large to avoid causing poor NVH of the whole vehicle).

[0031] The step of sending the target torque to the generator to control the generator to enter the torque control mode includes: Acquiring a remaining power percentage of the vehicle, determining a corresponding torque according to the remaining power percentage, and sending the torque as a target torque to the generator; During the regeneration control, the remaining power percentage of the vehicle is monitored in real time, and when the remaining power percentage of the vehicle is higher than a threshold, the torque is reduced and the regeneration control is performed again; When the remaining power percentage of the vehicle is lower than a threshold, the torque is reduced and then the regeneration control is performed again until the regeneration is completed.

[0032] Among them, the control mode of the generator is torque control, and the output torque is determined by the battery SOC. When the vehicle SOC does not reach a higher threshold (this threshold should be as large as possible, but not exceed the upper limit of the BMS's safe SOC), a torque of 10Nm (this value is not a fixed value, it can be calibrated according to the actual vehicle, so that the SOC does not rise too fast and the engine exhaust temperature can be increased) is sent. This can make the GPF combustion effect better. When the threshold is reached, a smaller torque value (usually 0Nm or 1Nm) is output to the generator. At this time, the energy SOC of the vehicle due to the loss of accessory power and engine speed control will slowly decrease. When it reaches a lower SOC value, the above operation is repeated over and over again until the GPF service station regeneration is completed. This method can protect the battery pack to the greatest extent and improve the regeneration efficiency of the GPF service station.

[0033] In addition, in some optional embodiments of the present invention, the method further includes: Acquiring a GPF service station regeneration status, and sending the GPF service station regeneration status to an engine controller; If a successful response is sent to the GPF service station for regeneration, the engine controller will perform the corresponding actions according to this status; If a component failure or vehicle conditions are not met, resulting in GPF service station regeneration failure, a prompt message is sent to the engine controller.

[0034] Among them, the regeneration status of the GPF service station is sent to the EMS. If the response to the GPF service station regeneration is sent successfully, the EMS will perform corresponding actions according to this status. If it is due to component failure or vehicle conditions are not met, the specific reasons will also be fed back to the EMS, and the EMS will interact with the diagnostic instrument to display the specific reasons for the failure of the after-sales engineer, which improves the simplicity of after-sales maintenance.

[0035] In summary, the GPF regeneration control method for a strong hybrid vehicle based on a service station in the above embodiment of the present invention determines whether the vehicle speed, gear position and parking brake state meet the preset conditions by receiving the GPF service station regeneration request flag sent by the engine; when it is determined that the vehicle speed, gear position and parking brake state meet the preset conditions, it determines whether the vehicle engine, generator and battery pack meet the preset conditions; when it is determined that the vehicle engine, generator and battery pack meet the preset conditions, it determines whether the GPF service station regeneration request meets the preset conditions; when it is determined that the GPF service station regeneration request meets the preset conditions, it controls the vehicle to enter the GPF service station regeneration state to regenerate the vehicle's GPF, and performs a comprehensive vehicle inspection before regeneration control to ensure that the regeneration conditions are met. The problem of poor effect of strong hybrid vehicle GPF regeneration control based on service stations in the prior art is solved.

[0036] In addition, the present invention has at least the following beneficial effects: 1. It can wait for the battery pack to heat up to the appropriate range before regenerating in the service station in a cold state, avoiding the situation where the battery cannot maintain the electrical balance when entering the GPF service station regeneration state at the beginning, thus ensuring the safety of the whole vehicle; 2. Determine whether it is the first regeneration and whether the regeneration time is reasonable, so as to ensure that manpower and material resources are not wasted; 3. Starting different loads to the generator according to SOC can protect the battery pack to the greatest extent and improve the regeneration efficiency of the GPF service station; 4. Sending the GPF service station regeneration status to EMS not only ensures the success of the GPF service station regeneration, but also reminds after-sales engineers of the specific reasons for failure, thus improving the simplicity of after-sales repair and maintenance.
