For better understanding of the technical solutions of the present invention, the following detailed descriptions of the embodiments of the present invention are provided with reference to the accompanying drawings.
It should be understood that the described embodiments are only some embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
In the related art, if the output power of the DCDC converter exceeds a safety threshold, it is liable to affect the driving safety of the vehicle. In order to solve the problem, embodiments of the present invention provide a load shedding method and a vehicle control system, which can distinguish multiple load shedding grades according to a difference between an output power and a safety threshold and/or a duration of the output power greater than or equal to the safety threshold when the output power of a DCDC converter is greater than or equal to the safety threshold, where each load shedding grade is associated with a load shedding policy for an energy consumption module, and different load shedding policies are respectively used to reduce a required power of the energy consumption module to different preset values, so as to reduce the output power of the DCDC converter.
Fig. 1 is a schematic diagram of a vehicle control system according to an embodiment of the present invention. As shown in fig. 1, the vehicle control system includes a vehicle control unit 11, a DCDC converter 12, and an energy consumption module 13, where the vehicle control unit 11 is connected to the DCDC converter 12 and the energy consumption module 13, respectively.
The DCDC converter 12 is configured to change a voltage of the direct current, so as to supply the energy consuming module with a suitable voltage.
The vehicle control unit 11 is configured to detect an output power of the DCDC converter 12; if the output power of the DCDC converter 12 is greater than or equal to the first threshold, determining a target load rejection level according to a difference between the output power and the first threshold and/or a duration of the output power greater than or equal to the first threshold; and executing the load throwing of the energy consumption module according to the load throwing strategy associated with the target load throwing grade.
Specifically, in the process of determining the target load rejection level, when the difference between the output power and the first threshold is smaller than the second threshold, if the duration of the output power being greater than or equal to the first threshold is greater than or equal to the third threshold and smaller than the fourth threshold, determining that the target load rejection level is the first-level load rejection; when the difference value between the output power and the first threshold is larger than a second threshold, or the duration of the output power larger than or equal to the first threshold is larger than or equal to a fourth threshold, determining that the target load throwing grade is a secondary load throwing grade; the primary load throwing and the secondary load throwing are respectively associated with different load throwing strategies, and the different load throwing strategies are respectively used for reducing the required power of the energy consumption module to different preset values.
When the target load throwing level is a first-level load throwing level, sending a first-level load throwing instruction to the energy consumption module 13 according to a first-level load throwing strategy, so that the energy consumption module 13 reduces the required power to a first preset value: when the target load throwing grade is the secondary load throwing grade, a secondary load throwing instruction is sent to the energy consumption module 13 according to a secondary load throwing strategy, so that the energy consumption module 13 reduces the required power to a second preset value, and the second preset value is smaller than the first preset value.
After the vehicle control unit 11 executes load shedding on the energy consumption module 13 according to the load shedding strategy associated with the target load shedding level, if the output power of the DCDC converter 12 is recovered to be within the first threshold, a load shedding closing instruction is sent to the energy consumption module 13, so that the energy consumption module 13 is adjusted up to the required power before load shedding.
In addition, the vehicle control system further includes a gear controller 14, and the gear controller 14 is connected to the vehicle control unit 11. After the vehicle control unit 11 executes load shedding on the energy consumption module according to the load shedding strategy associated with the target load shedding grade, if it is detected that the gear controller 14 is switched to the parking gear, a load shedding closing instruction is sent to the energy consumption module 13, so that the energy consumption module 13 is adjusted up to the required power before load shedding.
The energy consuming modules 13 may include a seat control module 15, a temperature control module 16, an in-vehicle infotainment module 17, and the like. The seat control module 15 can adjust the required power by controlling the on-off state of the heating, ventilating and massaging functions of the seat; the temperature control module 16 can adjust the required power by adjusting the temperature in the vehicle; the vehicle infotainment module 17 can adjust the required power by controlling the volume and the on-off state of the speaker.
For example, as an optional load shedding strategy, when the target load shedding level is a primary load shedding level, the vehicle control unit 11 may control the seat control module 15 to turn off the heating, ventilating and massaging functions of the seats other than the main driver seat, and control the in-vehicle infotainment module 17 to adjust the volume of the speaker down to 20; when the target load rejection level is the secondary load rejection level, the vehicle control unit 11 may control the seat control module 15 to turn off the heating, ventilating and massaging functions of all the driver seats, control the vehicle-mounted infotainment module 17 to turn off the speaker, and turn off the temperature control module 16.
Fig. 2 is a flowchart of a load shedding method according to an embodiment of the present invention. The method is applied to the vehicle control system shown in fig. 1, and the load shedding method is executed by a vehicle control unit in the vehicle control system. As shown in fig. 2, the load shedding method may include:
And 102, if the output power of the DCDC converter is greater than or equal to a first threshold, determining a target load rejection level according to a difference value between the output power and the first threshold and/or a duration of the output power greater than or equal to the first threshold.
And 103, executing the load throwing of the energy consumption module according to the load throwing strategy associated with the target load throwing grade.
Specifically, the vehicle control unit needs to determine whether the output power of the DCDC converter is greater than or equal to a first threshold after acquiring the output power. The first threshold value can be understood as a safety threshold value of the output power of the DCDC converter.
If the output power is greater than or equal to the first threshold, a difference between the output power and the first threshold and a duration for which the output power is greater than or equal to the first threshold need to be further determined.
And when the difference value between the output power and the first threshold is smaller than a second threshold, if the duration is greater than or equal to a third threshold and smaller than a fourth threshold, determining that the target load throwing grade is first-level load throwing.
And when the difference value between the output power and the first threshold is greater than a second threshold, or the duration is greater than or equal to a fourth threshold, determining that the target load throwing grade is a secondary load throwing grade.
Preferably, the first threshold is 2700W, the second threshold is 150W, the third threshold is 5 minutes, and the fourth threshold is 5 minutes and 15 seconds. At this time, the condition for determining that the target load rejection level is the first-level load rejection level is as follows: the output power of the DCDC converter is not less than 2700W and not more than 2850W (2850W is the first threshold value plus the second threshold value), and meanwhile, the duration of the output power not less than 2700W is greater than or equal to 5 minutes and not more than 5 minutes and 15 seconds.
The condition for determining the target load throwing grade as the secondary load throwing grade comprises two conditions, and the condition that the target load throwing grade is the secondary load throwing grade can be determined when any one condition is met. The first method comprises the following steps: the output power of the DCDC converter exceeds 2850W. And the second method comprises the following steps: the duration of the output power of not less than 2700W is 5 minutes or more and 15 seconds or less.
It should be noted that each load rejection level is associated with a load rejection strategy, and different load rejection strategies are respectively used for reducing the required power of the energy consumption module to different preset values.
For example, when the target load throwing level is a primary load throwing level, a primary load throwing instruction is sent to the energy consumption module according to a primary load throwing strategy associated with the primary load throwing level, so that the energy consumption module reduces the required power to a first preset value; and when the target load throwing grade is a secondary load throwing grade, sending a secondary load throwing instruction to the energy consumption module according to a secondary load throwing strategy associated with the secondary load throwing grade, so that the energy consumption module can reduce the required power to a second preset value. Wherein the second preset value is smaller than the first preset value. It can be understood that the higher the target load rejection level is, the smaller the preset value to which the energy consumption module in the corresponding load rejection strategy adjusts the required power is.
The energy consumption module can comprise a seat control module, a temperature control module and a vehicle-mounted information entertainment module. The seat control module can control the on-off state of the heating, ventilating and massaging functions of the seat to adjust the required power; the temperature control module can adjust the required power by adjusting the temperature in the vehicle; the vehicle-mounted infotainment module can adjust the required power by controlling the volume and the switch state of the loudspeaker.
In addition, the energy consumption module can also comprise an atmosphere lamp, a head-up display, an external power supply USB interface and the like. As an optional load throwing strategy, when the target load throwing grade is a first-level load throwing grade, the vehicle controller can control the seat control module to close the heating, ventilating and massaging functions of seats except the main driver seat, control the vehicle-mounted information entertainment module to adjust the volume of the loudspeaker to 20, and close the USB interface for external power supply; when the target load throwing grade is the secondary load throwing grade, the vehicle control unit can control the seat control module to close heating, ventilating and massaging functions of all the drivers' seats, control the vehicle-mounted information entertainment module to close the loudspeaker, and close the atmosphere lamp, the head-up display and the temperature control module.
It should be noted that the load shedding policy is only an example, and a user may modify load shedding policies corresponding to different load shedding levels according to actual requirements.
After step 103 is executed, if it is detected that the output power of the DCDC converter is restored to be within the first threshold, a countdown is started; if the countdown is finished and the output power of the DCDC converter is recovered to be below a fifth threshold (preferably, the fifth threshold is 2000W), a load throwing closing instruction is sent to the energy consumption module, so that the energy consumption module is adjusted up to the required power before load throwing, even if the energy consumption module is recovered to be in a non-throwing state. The countdown duration may be the duration mentioned in the foregoing step, that is, the duration in which the output power of the DCDC converter is greater than or equal to the first threshold.
As another alternative, after step 103 is performed, if it is detected that the output power of the DCDC converter is restored within the first threshold, a countdown is started; and if the countdown is finished and the gear controller is detected to be switched to the parking gear, sending a load throwing closing instruction to the energy consumption module so that the energy consumption module is adjusted to the required power before load throwing, even if the energy consumption module is recovered to the non-throwing state.
By setting the countdown method, the frequent switching of the vehicle before the load throwing state and the non-throwing state can be avoided.
According to the load shedding method provided by the embodiment of the invention, when the output power of the DCDC converter is greater than or equal to the first threshold, a plurality of load shedding grades are distinguished according to the difference value between the output power and the first threshold and/or the duration of the output power greater than or equal to the first threshold, each load shedding grade is associated with a load shedding strategy for an energy consumption module, and different load shedding strategies are respectively used for reducing the required power of the energy consumption module to different preset values so as to reduce the output power of the DCDC converter. According to the load shedding method provided by the embodiment of the invention, the DCDC converter can be protected and the normal running of the vehicle can be kept on the premise of reducing the influence on the riding experience of the user as much as possible by grading the load shedding grades.
