It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
Example 1
Fig. 1 is a flowchart of a method for determining engine starting capability according to an embodiment of the present invention, where the embodiment is applicable to a situation where the engine starting capability of a vehicle is determined before the vehicle is not started. The method may be performed by an engine starting capability determination device, which may be implemented in software and/or hardware.
Before the technical scheme of the embodiment of the invention is introduced, an application scene for implementing the technical scheme of the embodiment is introduced in an exemplary manner. Of course, the following application scenario is only an optional application scenario, and the present embodiment may also be implemented in other application scenarios, and the application scenario of the implemented technical method is not limited in this embodiment. Specifically, the application scenario includes: the existing method for judging the starting capability of the current engine is mostly based on the SOC of the storage battery, and alarms are given when the SOC is lower than a certain threshold value; some vehicle models increase the battery temperature to correct, and at low temperatures, the SOC limit is appropriately set high, but the problem that even if the SOC is the same after battery aging, the discharge capability is greatly different is not considered.
Based on the technical problems, the technical scheme of the embodiment of the invention mainly comprises the steps of calculating the maximum power consumed by the resistance in the starting process of the engine and the dischargeable power of the current state of the storage battery, reserving a part of power consumed by the basic load, comparing the maximum power consumed by the basic load with the dischargeable power of the current state of the storage battery, judging the current starting capability, and if the starting risk exists, alarming by an instrument, so that the judgment on the starting capability of the engine is more accurate.
Based on the technical thought, the technical scheme of the embodiment of the invention specifically obtains the internal resistance weighting coefficient, the health state weighting coefficient and the temperature of the storage battery in the vehicle, and determines the discharge power of the storage battery based on the internal resistance weighting coefficient, the health state weighting coefficient and the temperature of the storage battery; the more accurate discharge power of the storage battery is obtained; acquiring the current engine water temperature of an engine in a vehicle, a preset maximum power consumption database of engine starting resistance and load consumption power of the vehicle in the starting process, and determining the vehicle starting required power of the vehicle in the starting process; based on the average value of the maximum power consumed by the historical engine starting resistance, the prediction of the engine starting capability is more reliable, and the engine starting required power obtained by adding the load consumed power is more practical; determining an engine starting capability of the vehicle based on the vehicle starting required power and the battery discharge power; the starting capability of the obtained engine is more accurate, so that the judging result is more reliable.
As shown in fig. 1, the method specifically includes the following steps:
S110, acquiring a battery internal resistance weighting coefficient, a battery health state weighting coefficient and a battery temperature of a battery in the vehicle, and determining the battery discharge power of the battery based on the battery internal resistance weighting coefficient, the battery health state weighting coefficient and the battery temperature.
In the embodiment of the invention, the internal resistance weighting coefficient of the storage battery can be used for representing the actual available electric quantity of the storage battery; specifically, the internal resistance weighting coefficient of the storage battery can be obtained in real time through the storage battery sensing module. The battery state of health weighting coefficient may be used to represent the degree of aging of the battery; specifically, the battery state of health weighting coefficient may be obtained in real time by the battery sensing module. The battery temperature may be used to represent the real-time temperature of the battery as it is discharged; specifically, the battery temperature may be obtained by a battery sensing module.
Specifically, after the internal resistance weighting coefficient, the health state weighting coefficient and the temperature of the storage battery are obtained, the above storage battery parameters are sent to an electric quantity calculation module through the LIN bus, and the electric quantity calculation module can determine the discharge power of the storage battery based on the internal resistance weighting coefficient, the health state weighting coefficient and the temperature of the storage battery.
Optionally, the method for determining the battery discharge power of the battery may include: acquiring a preset storage battery calibration discharge power database, and determining the calibration discharge power of the storage battery based on the temperature of the storage battery and the storage battery calibration discharge power database; and determining the battery discharge power of the battery based on the battery internal resistance weighting coefficient, the battery state of health weighting coefficient and the calibrated discharge power.

Further, the calibration discharge power is multiplied by the internal resistance weighting coefficient of the storage battery and the health state weighting coefficient of the storage battery to obtain the discharge power of the storage battery.
It should be noted that, because the technical scheme provided by the embodiment of the invention considers the aging degree of the storage battery and the actual condition of the actual available electric quantity of the storage battery in the process of calculating the power of the storage battery, the obtained discharge power result of the storage battery is more accurate, so that the engine starting capability determined later is more accurate.

In the embodiment, a preset maximum power consumption database of engine starting resistance is obtained, and the water temperature of each engine in the database corresponds to the maximum power consumption of the engine starting resistance generated by a plurality of engines when the engines are started; since the starting makes the environments different, the maximum power consumed by each engine starting resistance corresponding to the same engine water temperature may not be equal; in order to reduce errors in calculating the power required for starting the vehicle in the present embodiment, in an engine starting resistance consumption maximum power database of the engine, a plurality of historical engine starting resistance consumption maximum powers corresponding to the current water temperature of the engine are read, and an average engine starting resistance consumption maximum power between the plurality of historical engine starting resistance consumption maximum powers is determined, so that the engine starting resistance consumption maximum power corresponding to the current water temperature of the engine is more reliable.
The plurality of historical engine starting resistance consumption maximum powers may be a plurality of historical engine starting resistance consumption maximum powers generated during starting at the current engine water temperature that was recently recorded. Of course, the number of the selected maximum power consumed by the historical engine starting resistance is not limited in this embodiment, and may be selected according to actual situations.
Further, the vehicle start required power during the start of the vehicle is determined based on the average engine starting resistance consumed maximum power and the load consumed power.
In addition, in the process of calculating the power required for starting the vehicle, the actual condition that the load consumes power when the controller works in the starting process of the engine is considered, so that the obtained power required for starting the vehicle is more accurate, and the starting capability of the engine determined later is more accurate.

And S130, determining the engine starting capability of the vehicle based on the power required for starting the vehicle and the discharge power of the storage battery.
In an embodiment of the present invention, a method of determining engine starting capability of a vehicle may include: a difference between the battery discharge power and the power required for starting the vehicle is determined, and the difference is used as an engine starting capability of the vehicle.
Specifically, the process of determining the required starting power of the vehicle and the discharging power of the storage battery considers the current engine starting state of the vehicle and the real-time state of the storage battery, so that the obtained engine starting capability is more reliable.
The technical scheme of the embodiment of the invention comprises the steps of obtaining a storage battery internal resistance weighting coefficient, a storage battery health state weighting coefficient and a storage battery temperature of a storage battery in a vehicle, and determining the storage battery discharge power of the storage battery based on the storage battery internal resistance weighting coefficient, the storage battery health state weighting coefficient and the storage battery temperature; the more accurate discharge power of the storage battery is obtained; acquiring the current engine water temperature of an engine in a vehicle, a preset maximum power consumption database of engine starting resistance and load consumption power of the vehicle in the starting process, and determining the vehicle starting required power of the vehicle in the starting process; based on the average value of the maximum power consumed by the historical engine starting resistance, the prediction of the engine starting capability is more reliable, and the engine starting required power obtained by adding the load consumed power is more practical; determining an engine starting capability of the vehicle based on the vehicle starting required power and the battery discharge power; the starting capability of the obtained engine is more accurate, so that the judging result is more reliable.

In contrast, the quick start prompt message corresponding to the first starting capability threshold value indicates that the current electric quantity of the storage battery is relatively low, and if the vehicle is not started within a certain time, the risk of incapability of starting the vehicle after the vehicle is also present.
