Detailed Description

For the purposes of making the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail below with reference to the accompanying drawings.

"upper", "lower", "left", "right", etc. are used merely to indicate relative positional relationships, which may also be changed when the absolute position of the object to be described is changed.

As described in the background, when a power battery of a vehicle fails, the vehicle enters a limp-home mode. Power battery faults include state machine faults, too low a residual charge, or power battery component faults. When these faults occur, the power battery sends a fault signal to the power domain control unit (Power Domain Control Unit, PDCU), which then controls the vehicle to enter a limp-home mode. In limp-home mode, the vehicle will disable the use of high voltage accessories to avoid unnecessary power consumption. The vehicle starts a faulty operation so that the vehicle can travel to a roadside stop or repair shop for repair. If the current environment temperature of the vehicle is too high or too low, the air conditioner cannot be started, so that the body health of a user can be damaged, frostbite or heatstroke occurs, and the driving comfort cannot be ensured. In view of this, the present application proposes an air conditioner control method to meet the air conditioner usage requirement of the vehicle in the limp mode.

Embodiments of the present application are described in detail below with reference to the accompanying drawings.

The application provides an air conditioner control method, which is applied to a power domain control unit PDCU, and referring to FIG. 1, the method comprises the following steps:

step 102, controlling an engine of the vehicle to enter a disabled state in response to receiving the power battery fault signal.

Specifically, when the power battery fails, the sensor of the power battery may send a power battery failure signal to the power domain control unit, where the power battery failure signal may include a power battery state machine failure signal, a residual electric quantity deficiency failure signal, or a power battery component failure signal. And after the PDCU receives the power battery fault signal, controlling the vehicle to enter a limp mode. At this time, if the engine is not started, the engine is controlled to start and keep running continuously while the engine stop is prohibited. If the engine has started, the engine is controlled to maintain continuous operation and engine shutdown is inhibited. The continuous operation of the engine not only can provide driving force for the vehicle, but also can drive the motor to generate electricity. Because the power battery can not provide power demand for the vehicle at this moment, then drive the motor by the engine and generate electricity, and then supply power for high-voltage accessory and low-voltage accessory in the vehicle, provide necessary power consumption demand for the consumer in the vehicle, prevent that the vehicle from because the feed is down electric, avoid the vehicle to cause the potential safety hazard because of unable start.

It should be noted that, if the vehicle is in the idle mode at this time, the engine speed is controlled to rise from the idle speed to the target speed, and the target speed is higher than the idle speed of the vehicle, so as to prevent the vehicle from being powered off due to power feeding occurring due to power consumption of the high-voltage accessory at a low speed. For example, if the idle speed of the vehicle is 800rpm, the target speed is 1400rpm.

And 104, responding to the received air conditioner regulation request, and determining available power of the air conditioner according to the current power generation power and the current high-voltage accessory consumption power of the vehicle, wherein the current power generation power is generated by driving a motor to generate electricity by the engine.

Specifically, if the user has an air conditioner use requirement at this time, the air conditioner temperature is adjusted through a human-computer interaction interface or a physical key in the vehicle, and then the air conditioner controller sends an air conditioner adjusting and controlling request to the PDCU. After the PDCU receives the air conditioner control request, it needs to allocate available power to the air conditioner. Because the engine is used for providing power for the vehicle, the engine drives the motor to generate power, and the power is directly supplied for the high-voltage accessories and the low-voltage accessories. In addition to the power requirements of the air conditioner, other high voltage accessories have the necessary power requirements, such as a dc converter, etc. In the current power generated by the motor, the rest power can be distributed to the air conditioner controller except the power consumption necessary for other high-voltage accessories of the vehicle. Accordingly, the available power for the air conditioner may be determined based on the current generated power and the current high voltage accessory consumption power.

And step 106, sending the available power of the air conditioner to an air conditioner controller so that the air conditioner controller controls the operation of the air conditioner according to the available power of the air conditioner.

After the available power of the air conditioner is determined, the PDCU sends the available power to an air conditioner controller, and the air conditioner controller controls the air conditioner to operate according to the available power to provide heating or refrigerating functions. In the running process of the air conditioner, the power consumed by the air conditioner does not exceed the available power of the air conditioner, so that the use requirement of a user on the air conditioner can be met, the power consumption of the air conditioner can be reduced, the energy consumption of an engine can be further reduced, and the emission pollution of a vehicle can be reduced.

Based on the steps 102 to 106, the air conditioner control method provided in the embodiment includes: and in response to receiving the power battery fault signal, controlling an engine of the vehicle to enter a forbidden state, wherein the engine can continuously run to provide driving force for the vehicle and drive a motor to generate power so as to provide electric quantity support for electric equipment of the vehicle, and the vehicle can maintain fault operation and ensure running safety of the vehicle under the fault condition. And in response to receiving the air conditioner regulation request, determining available power of the air conditioner according to the current power generated by the motor driven by the engine to generate electricity and the current high-voltage accessory consumption power of the vehicle. If the user has the air conditioner use requirement at this time, the available power is reasonably distributed for the air conditioner besides ensuring the electric quantity consumption necessary for the running of the vehicle, so that the air conditioner use requirement of the user is realized, and the driving comfort is improved. The electric quantity consumption necessary for the running of the vehicle mainly comes from the current high-voltage accessory consumption, and the available power of the air conditioner can be determined through the generated power of the current motor and the current high-voltage accessory consumption. The available power of the air conditioner is sent to the air conditioner controller, so that the air conditioner controller controls the air conditioner to operate according to the available power, the power consumption in the air conditioner operation process cannot exceed the limit of the available power, the air conditioner use requirement of a user can be met, the energy consumption of the air conditioner can be reduced as much as possible, and the environment-friendly requirement of vehicle running is met.

The method for determining the available power of the air conditioner is described below by way of specific embodiments.

In some embodiments, the determining the available power of the air conditioner according to the current power generated by the motor driven by the engine and the current high-voltage accessory consumption power of the vehicle comprises:

Specifically, when the available power of the air conditioner is determined, the difference between the current power generation power and the current power consumption of the high-voltage accessory can be used as the available power of the air conditioner. Because the power battery breaks down at this time, the motor is driven by the engine to generate electricity so as to preferentially ensure the necessary electric quantity consumption generated when the vehicle runs in a fault, and unnecessary electric quantity consumption can be forbidden. Current high voltage accessory consumption includes high voltage line loss power and dc converter consumption power. The high-voltage line provides the electric quantity transmission function for the high-voltage accessory of vehicle, and the high-voltage line itself will produce certain heat because of the existence of resistance when carrying the electric quantity, consumes a part of electric quantity, and the power that this part of electric quantity that consumes corresponds is high-voltage line loss power. In order to avoid the vehicle from being powered down when the vehicle is in fault operation, the electric quantity requirement exists on part of low-voltage accessories of the vehicle, and the low-voltage accessories need to be provided with the direct-current converter to provide the low-voltage power. A Direct Current-to-Direct Current converter (DCDC) converter converts the high voltage power generated by the motor into a low voltage power for use by the low voltage accessory. Both the high voltage line loss power and the direct current converter consumption power are power consumption necessary for the current vehicle running, and therefore, the current high voltage accessory consumption power at least comprises the high voltage line loss power and the direct current converter consumption power. After the high-voltage line loss power and the power consumed by the direct-current and direct-current converter are removed from the current generated power, the remaining power can be distributed to an air conditioner as the available power of the air conditioner. Therefore, on the premise of ensuring the necessary power consumption for the running of the vehicle, the air conditioner using requirement of a user can be met, the situation that the vehicle is powered off due to power feeding is avoided, and the driving comfort of the user is improved.

In order to further reduce the energy consumption of the vehicle when determining the available power of the air conditioner, the available power of the air conditioner may be determined together with a preset calibration power, which is described in the following by a specific embodiment.

taking the difference value between the current power generation power and the current high-voltage accessory consumption power as a first available power; and taking the smaller value of the first available power and the preset calibration power as the available power of the air conditioner.

Specifically, as in the previous embodiment, when determining the available power of the air conditioner, the difference between the current generated power and the current high-voltage accessory consumed power is first determined, and the difference is taken as the first available power. The first available power is the maximum available power that the current air conditioner can use. Meanwhile, in the limp-home mode of the vehicle, a calibration power is preset, which ensures that the air conditioner can be successfully started and operated in a lower gear, for example, in first gear. The nominal power is, for example, 2000W. After the first available power is determined, comparing the first available power with the calibration power, taking the smaller value of the first available power and the calibration power as the available power of the air conditioner, taking the first available power as the available power of the air conditioner if the first available power value is smaller, and taking the calibration power as the available power of the air conditioner if the calibration power value is smaller. The air conditioner can be started to run, heating or refrigerating requirements are provided for users, the available power of the air conditioner can be further reduced, and the energy consumption of the air conditioner is reduced.

The method of determining the present generated power is described below by way of specific embodiments.

In some embodiments, referring to fig. 2, the method for determining the current generated power includes the following steps:

step 202, obtaining the current engine speed, the current vehicle speed and the current high-voltage accessory consumption power.

Specifically, the current power generated by the motor is changed in real time according to the actual demand of the user. Because the engine drives the motor to generate electricity at the moment, the engine drives the motor to rotate reversely through the output load adjusting torque to generate electricity. The load adjustment torque is a negative torque. When determining the load adjustment torque, it is necessary to obtain the current engine speed, the current vehicle speed and the current high-voltage accessory consumption in real time to determine the real-time load adjustment torque, that is, the current load adjustment torque.

Step 204, determining the current load adjusting torque of the engine according to the current engine speed, the current vehicle speed and the current high-voltage accessory consumption power.

Specifically, the engine outputs a whole vehicle required torque, and the whole vehicle required torque comprises a driving torque and a load adjusting torque, wherein the driving torque provides driving force for the vehicle, and the load adjusting torque drives the motor to generate power. The driving torque is positive torque and the load adjusting torque is negative torque. The engine outputs the whole vehicle required torque, generates a certain rotating speed, the vehicle starts to operate and generates a certain vehicle speed, and the energy consumption of the power consumption of the high-voltage accessory comes from the load adjusting torque. Therefore, the determination of the load adjustment torque has a certain correlation with the engine speed, the vehicle speed and the high-voltage accessory consumption power. The current load adjusting torque can be determined through the current engine speed, the current vehicle speed, the current high-voltage accessory consumption power and the pre-calibrated association relation. And determining the corresponding relation among the current engine speed, the current vehicle speed, the current high-voltage accessory consumption power and the current load adjusting torque in the pre-calibrated association relation. The pre-calibrated association is determined according to a plurality of real vehicle tests.

And 206, determining the current power generation power according to the current load adjusting torque.

After the load adjusting torque is determined, the current power generation power can be calculated according to the relation between the load adjusting torque and the power generation power of the motor. Motor generated power = motor rotational speed generated torque (load adjustment torque)/9549, the current generated power can be determined by the current load adjustment torque and the above-described correspondence.

By the method for determining the current power generation power in the embodiment, the current power generation power can be accurately determined according to the vehicle related data (the engine speed, the vehicle speed and the high-voltage accessory consumption power) related to the power generation power, the calculation accuracy of the current power generation power is improved, and more reasonable available power is further distributed for the air conditioner.

The method of determining the current load adjustment torque is specifically described below by way of example.

In some embodiments, the determining the current load adjustment torque of the engine based on the current engine speed, the current vehicle speed, and the current high pressure accessory consumption power comprises:

determining a first adjusting torque according to a preset mapping relation based on the current engine speed and the current vehicle speed; determining a second adjusting torque according to a preset mapping relation based on the current engine speed, the current high-voltage accessory consumption power and the preset consumption power; and taking the smaller value of the first adjusting torque and the second adjusting torque as the current load adjusting torque.

Specifically, the preset mapping relationship is a corresponding relationship determined in advance according to the real vehicle test. The preset mapping relation comprises a first mapping relation and a second mapping relation. In the first map, a correspondence of a current engine speed, a current vehicle speed, and a first adjustment torque is determined. In the second mapping relation, the corresponding relation among the current engine speed, the current high-voltage accessory power consumption, the preset power consumption and the second regulating torque is determined. And determining a first regulating torque according to a first mapping relation according to the current engine speed and the current vehicle speed. In the first map, when the vehicle speed is fixed, the first adjustment torque tends to increase and then decrease with an increase in the engine speed. Meanwhile, when the engine speed is smaller than the first speed, the first regulating torque is a first constant value, and when the engine speed is larger than the second speed, the first regulating torque is a second constant value, namely the first constant value is a lower limit value of the first regulating torque, and the second constant value is an upper limit value of the first regulating torque. When the engine speed is fixed, the first regulating torque is proportional to the vehicle speed. According to the current engine speed and the current vehicle speed, a unique first regulating torque can be determined according to a first mapping relation.

In the second mapping relation, when the power consumption of the high-voltage accessory and the preset power consumption are fixed, the second regulating torque tends to increase and decrease firstly along with the increase of the rotating speed of the engine. Meanwhile, the second regulating torque is a third constant value when the engine speed is smaller than the first speed, and is a fourth constant value when the engine speed is larger than the second speed, namely the third constant value is a lower limit value of the second regulating torque, and the fourth constant value is an upper limit value of the second regulating torque. The preset power consumption is a fixed value, and represents the corresponding power of the air conditioner in the low gear operation, such as the power generated by the air conditioner in the first gear operation. Current high voltage accessory power consumption includes at least high voltage line loss power and dc to dc converter power consumption. At this time, because the user has the air conditioner use demand, the preset power consumption is increased on the basis of the current high-voltage accessory power consumption, so as to request larger load adjusting torque to the engine and meet the air conditioner use demand. The second regulated torque is proportional to the current high pressure accessory power consumption when the engine speed is fixed. The greater the current high voltage accessory consumes power, the greater the second regulating torque. And determining a unique second regulating torque according to a second mapping relation according to the current engine speed, the current high-voltage accessory power consumption and the preset power consumption.

By the method for determining the current power generation power in the embodiment, the current power generation power can be accurately determined according to vehicle related data (engine speed, vehicle speed and high-voltage accessory consumption power) related to the power generation power and a preset mapping relation, so that the calculation accuracy of the current power generation power is improved, and more reasonable available power is further distributed for an air conditioner.

After the vehicle enters the limp-home mode, if the user does not have the air conditioner use requirement, the power consumption requirement necessary when the vehicle runs in a fault can be met when the load adjustment torque is requested to the engine. The following is a description of specific examples.

In some embodiments, the method further comprises:

Specifically, after the vehicle enters the limp-home mode, if the current user does not have the air conditioner use requirement, the power consumption required by the vehicle fault operation can be met when the engine drives the motor to generate power, the excessive load regulation torque output by the engine is avoided, and the energy consumption of the engine is reduced. When determining the necessary electricity consumption for the faulty operation of the vehicle, the electricity consumption needs to be determined according to the current operation information of the vehicle. The current operating information may include real-time vehicle information such as engine speed, vehicle speed, etc. After the current load adjusting torque is determined according to the current running information, the current load adjusting torque is sent to the engine, so that the engine outputs the load adjusting torque and drives the motor to generate power, power is supplied to the high-voltage accessories and the low-voltage accessories which are necessary for running the vehicle, the phenomenon that the vehicle is powered off due to flameout of the power supply is avoided, and the running safety of the vehicle during fault running is ensured.

A method of determining the current load adjustment torque based on the current operating information is described below with specific embodiments.

In some embodiments, the current operating information includes a current engine speed, a current vehicle speed, and a current high-pressure accessory consumption power; the determining the current load adjusting torque of the engine according to the current running information comprises the following steps:

Specifically, the current operating information includes a current engine speed, a current vehicle speed, and a current high-voltage accessory consumption power. The preset mapping relation is a corresponding relation determined in advance according to the real vehicle test. The preset mapping relation comprises a first mapping relation and a second mapping relation. And determining a first regulating torque according to a first mapping relation according to the current engine speed and the current vehicle speed. In the first map, when the vehicle speed is fixed, the first adjustment torque tends to increase and then decrease with an increase in the engine speed. Meanwhile, when the engine speed is smaller than the first speed, the first regulating torque is a first constant value, and when the engine speed is larger than the second speed, the first regulating torque is a second constant value, namely the first constant value is a lower limit value of the first regulating torque, and the second constant value is an upper limit value of the first regulating torque. When the engine speed is fixed, the first regulating torque is proportional to the vehicle speed. According to the current engine speed and the current vehicle speed, a unique first regulating torque can be determined according to a first mapping relation.

In the second map, when the high-voltage accessory consumes a certain power, the second regulating torque tends to increase and decrease with the increase of the engine speed. Meanwhile, the second regulating torque is a third constant value when the engine speed is smaller than the first speed, and is a fourth constant value when the engine speed is larger than the second speed, namely the third constant value is a lower limit value of the second regulating torque, and the fourth constant value is an upper limit value of the second regulating torque. Current high voltage accessory power consumption includes at least high voltage line loss power and dc to dc converter power consumption. The second regulated torque is proportional to the current high pressure accessory power consumption when the engine speed is fixed. The greater the current high voltage accessory consumes power, the greater the second regulating torque. And determining a unique second regulating torque according to a second mapping relation according to the current engine speed and the current high-pressure accessory consumption power.

By the method for determining the current power generation power in the embodiment, the current power generation power can be accurately determined according to the vehicle related data (the engine speed, the vehicle speed and the high-voltage accessory consumption power) related to the power generation power and the preset mapping relation, and the calculation accuracy of the current power generation power is improved so as to meet the power consumption requirement when the vehicle runs in a fault mode. Meanwhile, through accurate calculation of the current power generation power, excessive load adjustment torque output by the engine can be avoided, and the energy consumption of the engine is further reduced.
