Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a schematic flow chart of a vehicle control method according to an embodiment of the present invention, where the embodiment is applicable to controlling vehicle power, and the method may be executed by a vehicle control device. As shown in fig. 1, the method specifically includes the following steps:
The current driving state parameters of the vehicle may be obtained by an Electronic Stability Program (ESP), and the driving state parameters may include a maximum vehicle speed, an average vehicle speed, and a maximum acceleration over a period of time, and the parameters may be obtained by the ESP. The working condition type is a running condition of the vehicle on the road, for example, the working condition type can be divided into a congestion type, a normal type, a high-speed type and the like, and according to the current running state parameter, the working condition type corresponding to the current running state parameter can be determined and used as the current working condition type of the vehicle in the current period of time.
In this embodiment, optionally, determining the current operating mode type of the vehicle according to the current driving state parameter of the vehicle includes: acquiring at least one preset candidate working condition type and a standard driving state parameter corresponding to the candidate working condition type; and comparing the current running state parameters of the vehicle with the standard running state parameters to determine the current working condition type of the vehicle.
Specifically, different working condition types are preset as candidate working condition types, each working condition type is provided with a corresponding standard running state parameter, the current running state parameter of the vehicle is compared with the preset standard running state parameter, the standard running state parameter consistent with the current running state parameter is searched, and the working condition type corresponding to the standard running state parameter is used as the current working condition type. For example, two candidate working condition types A and B are preset, the standard running state parameter of A is that the maximum speed is between 30km/h and 40km/h, the standard running state parameter of B is that the maximum speed is between 10km/h and 20km/h, and the current maximum speed of the vehicle is 15km/h, and then the current working condition type of the vehicle is determined to be the type A. The beneficial effect who sets up like this lies in, through predetermineeing candidate operating mode type, is favorable to confirming the current operating mode type of vehicle fast to improve the control efficiency of vehicle.
And step 120, determining the target charge state of the battery under the current working condition type according to the current working condition type.
After the current working condition type is determined, the target charge state of the battery under the working condition type is obtained, the target charge state is an expected charge state value under different working condition types, the charge state can be represented by SOC, and the higher the SOC is, the more the battery heats. By determining the current working condition type, the working condition type of the vehicle on the whole running route and the change trend of the working condition type can be defined, and different target SOCs can be set for different working condition types, so that the SOC required by the whole vehicle can also change along with the target SOC along with the change of the working condition type of the vehicle.
In this embodiment, optionally, determining the target state of charge of the battery under the current operating condition type according to the current operating condition type includes: determining a preset standard charge state associated with the current working condition type according to the current working condition type; and comparing the current battery temperature with the standard battery temperature, and adjusting the standard charge state according to the comparison result to obtain the target charge state.
Specifically, the standard charge state under different candidate working condition types is preset, and after the current working condition type is determined, the standard charge state corresponding to the current working condition type is searched. And then obtaining the current Battery temperature from a BMS (Battery Management System), comparing the current Battery temperature with a preset standard Battery temperature, and adjusting the standard state of charge according to the comparison result to obtain the target state of charge. For example, if the current battery temperature is low, the target SOC may be appropriately increased, and if the current temperature is high, the target SOC may be appropriately decreased. The adjustment magnitude may be preset, for example, to raise the target SOC by 5 charge values every 1 degree celsius lower in temperature. The method has the advantages that the target charge state can be obtained quickly, the obtained target charge state is associated with the current battery temperature, the current state of the vehicle is met, and the accuracy of vehicle control is improved.
And step 130, determining the required power of the battery according to the actual charge state and the target charge state of the battery.
The actual state of charge is a current SOC value of the battery, and the power required by the battery from the actual state of charge to the target state of charge, that is, the power that the battery should be charged or discharged, may be determined according to the actual state of charge and the target state of charge of the battery, where the power is the power required by the battery.
In this embodiment, optionally, determining the required power of the battery according to the actual state of charge and the target state of charge of the battery includes: acquiring the actual charge state of the battery; and determining the required power of the battery according to the actual charge state and the target charge state of the battery.
Specifically, the actual state of charge of the battery may be obtained from the BMS system, the actual state of charge of the battery may be compared with the target state of charge, and the required power of the battery may be determined according to the comparison result. The required power of the battery may be determined based on a difference between an actual state of charge and a target state of charge of the battery, for example, a difference between the actual state of charge and the target state of charge may be determined using a euclidean distance calculation. The beneficial effect that sets up like this lies in, through comparing actual state of charge and target state of charge, can obtain the real required power of battery, through confirming battery required power, has increased the dimension of considering to whole car required power, has improved the computational accuracy to whole car required power.
And 140, determining the whole vehicle required power of the vehicle according to the battery required power and the running required power of the vehicle so as to control the running of the vehicle according to the whole vehicle required power.
Wherein the power demand for driving is determined on the basis of the torque demand of the vehicle and the actual rotational speed of the electric machine, e.g. torque is denoted by T and rotational speed is denoted by n, the power demand for driving can be formulated
And calculating, wherein P is the required driving power, and 9550 is a set parameter.
After the required driving power is determined, the required driving power can be corrected according to the required battery power, the corrected result is the required finished automobile power, and the required finished automobile power is provided by the APU, so that the APU can control the automobile to drive according to the required finished automobile power. The required power of the battery is used for properly correcting the required driving power, so that the required power of the whole vehicle can better accord with the working state of the current working condition type of the vehicle. The more power the APU provides, the less power the battery provides, and the less power the APU provides, the more power the battery provides, effectively avoiding battery and engine depletion. In a high-speed and stable traffic environment, the APU provides more power, so that the battery discharges or charges at a small multiplying power and always works under a better current working condition; when the vehicle is in a low-speed or frequently started and stopped traffic environment, the APU provides less power or even does not provide power, so that the battery is taken as an energy source to be dominant, and the power control in the running process of the vehicle is realized.
According to the technical scheme, the current working condition type of the vehicle is determined by obtaining the current running state parameter, the required power of the battery is determined according to the working condition type, and the required power of the whole vehicle is determined according to the required power of the battery and the required running power, so that the power of the APU is controlled in the running process of the vehicle.

And step 220, determining the target charge state of the battery under the current working condition type according to the current working condition type.

And step 250, determining the required power of the whole vehicle according to the required power of the battery, the required driving power of the vehicle and the required working condition power.
When the required power of the whole vehicle is calculated, two dimensions of the required power of the battery and the required power of the working condition are increased besides the required driving power. The working condition required power is the average power in a statistical period of time, the value of the working condition required power can well reflect the overall power requirement condition of the vehicle, the working condition required power is relatively stable, and large-amplitude fluctuation cannot occur. The SOC of battery changes slowly, and under the unchangeable condition of operating mode, battery demand power also can not great change, and the numerical value tends to stable. Because the battery required power and the working condition required power are relatively stable, severe fluctuation can not be generated along with the operation of a driver, and the fluctuation can be greatly reduced when the power of the APU (auxiliary Power Unit) is calculated, namely the power required by the whole vehicle, so that the working condition point conversion frequency of the engine is reduced, the economic characteristic and the emission characteristic of the engine are effectively improved, and the control efficiency of the vehicle is improved.

Specifically, the working condition required power and the running required power can be weighted according to a preset weight, and an intermediate value is obtained and recorded as the power required power. And correcting and adjusting the power demand power according to the battery demand power to obtain the finished automobile demand power, wherein the correction mode of the power demand power can be a calculation mode such as addition and subtraction. The beneficial effect who sets up like this lies in, through combining battery required power, the required power of going and the operating mode required power of vehicle, has effectively improved the computational accuracy of whole car required power to avoided APU frequent start-stop to provide whole car required power, made APU remain stable, improved the control efficiency of vehicle, and the life of engine and battery.
