Furthermore, features described with respect to some examples may be combined into other examples.
Referring to fig. 1, fig. 1 is a schematic flow chart of a control method for reducing energy consumption of a pure electric vehicle according to an embodiment of the present application. In an embodiment of the present application, the method includes:
s101, acquiring vehicle parameter data, and determining the state of the automobile according to the vehicle parameter data.
The execution subject of the present application may be a vehicle control unit.
The vehicle parameter data may be understood as vehicle related parameter data obtained by the vehicle controller, for example, vehicle speed, battery temperature, battery power, etc.
In the embodiment of the application, the electric automobile is provided with the energy recovery condition (for example, the automobile is in a non-stationary state, etc.), and the automobile can perform the energy recovery operation only when the energy recovery condition is met. To determine whether the vehicle satisfies the energy recovery condition, the vehicle state needs to be known, and the vehicle state may be determined from the vehicle parameter data.
S102, judging whether the automobile state meets a first energy recovery condition set or not.
In the embodiment of the application, after the automobile state is determined, the first energy recovery condition set which can comprise that the automobile is in a non-stationary state, the accelerator pedal of the automobile is released, the temperature of the battery of the automobile is in a normal temperature range and the like can be judged according to the automobile state.
In one embodiment, step S102 includes:
determining all front energy recovery conditions required by the vehicle for energy recovery, and inquiring and deleting the front energy recovery conditions representing the release of the accelerator pedal from a first energy recovery condition set to obtain a second energy recovery condition set, wherein the first energy recovery condition set comprises the front energy recovery conditions;
and judging whether the automobile state meets all the second energy recovery condition sets.
The precondition for energy recovery may be understood in the embodiments of the application as a precondition that each of the first set of conditions for energy recovery needs to meet.
In the embodiment of the application, the front energy recovery conditions may include various conditions required by the vehicle to perform the energy recovery operation, that is, under normal conditions, the vehicle needs to satisfy all the front energy recovery conditions to perform the energy recovery operation. After all the front energy recovery conditions are determined, the front energy recovery conditions corresponding to the working condition of releasing the accelerator pedal are inquired and screened, and deleted from the first energy recovery condition set, so that a second energy recovery condition set is obtained, and further the automobile state is judged through the second energy recovery condition set. That is, since the driver always performs the shifting operation by pressing the accelerator pedal during the running of the vehicle, the present application will preferentially determine other energy recovery conditions when determining the energy recovery conditions, and will perform the determination of the condition of releasing the accelerator pedal only when the other energy recovery conditions are satisfied.
And S103, when the automobile state does not meet the first energy recovery condition set, controlling the direct current converter to start working.
In the embodiment of the application, when the state of the automobile does not meet the first energy recovery condition set, namely, no energy which can be recovered is used for supplying energy to the system, so that the direct current converter is controlled to start working, and the high voltage is converted into the low voltage for energy supply.
In one embodiment, step S103 includes:
and when the automobile state does not meet all the second energy recovery condition sets, controlling the direct current converter to start working.
In the embodiment of the application, as long as the automobile state cannot meet the second set of energy recovery conditions, the direct current converter is controlled to start working even if the accelerator pedal is in a released state.
And S104, when the automobile state meets a first energy recovery condition set, controlling the direct current converter to stop working.
In the embodiment of the application, if the state of the automobile can meet the first set of energy recovery conditions, namely the automobile can recover energy at present, energy can be recovered to power the low-voltage system, so that the direct-current converter is not required to work, and under the working condition, the direct-current converter is controlled to stop working in order to reduce energy consumption.
In one embodiment, step S104 includes:
when the automobile state meets all the second energy recovery condition sets, controlling the direct current converter to stop working, and detecting the state of an accelerator pedal in real time;
when the accelerator pedal is detected to be completely released, the brake recovery energy is collected, and the direct current converter is supplied and controlled to start working based on the brake recovery energy.
In the embodiment of the application, when the automobile state meets the second energy recovery condition set, namely the whole automobile controller judges that all conditions except the condition of releasing the accelerator pedal meet the recovery condition, the control direct current converter is stopped to work at first for reducing the energy consumption, and the accelerator pedal state is monitored in real time. After the accelerator pedal is detected to be completely released, namely the current state of the vehicle meets all the front-end energy recovery conditions, an energy recovery process is carried out, and in the energy recovery process, the whole vehicle controller can collect braking recovery energy, and the braking recovery energy is used for supplying the direct-current converter, so that the direct-current converter is controlled to start working. It should be noted that under normal conditions, the dc converter is powered by the power battery of the automobile, and the recovered energy is used to supply the dc converter to work, so that the energy input into and output from the battery frequently can be effectively reduced, and the energy consumption loss of the battery in conversion efficiency due to frequent charging and discharging can be caused.
In one embodiment, the collecting brake recovered energy and supplying and controlling the dc converter to start operating based on the brake recovered energy includes:
collecting braking recovery energy, and obtaining the current electric quantity and the electric quantity descending rate of a low-voltage system of the whole vehicle;
calculating whether the estimated electric quantity after the preset waiting time is lower than a preset safety critical electric quantity or not based on the electric quantity decreasing rate and the current electric quantity;
when the estimated electric quantity is not lower than the safety critical electric quantity, the braking recovery energy is fully supplied to the direct current converter, and the direct current converter is controlled to start working;
and when the estimated electric quantity is lower than the safety critical electric quantity, supplying the power battery with the braking recovery energy based on the braking recovery energy until the estimated electric quantity is not lower than the safety critical electric quantity, supplying the rest braking recovery energy to the direct current converter, and controlling the direct current converter to start working.
The safety critical electric quantity can be understood as a preset critical value of the basic electric quantity required for ensuring the normal operation of the system in the embodiment of the application.
In the embodiment of the application, if the electric quantity of the system is low, the recovered energy is required to be used for supplying energy to the system preferentially in order to ensure the normal operation of the system, so that after the recovered energy is collected in braking, the current electric quantity and the electric quantity reduction rate of the low-voltage system of the whole vehicle are firstly obtained. The current electric quantity consists of the residual electric quantity of a power battery in the electric automobile and the residual electric quantity of a storage battery. The safety critical electric quantity is preset, and the system estimated electric quantity after a certain waiting time can be calculated according to the current electric quantity and the electric quantity descending rate. By comparing and judging the estimated electric quantity with the safety critical electric quantity, when the estimated electric quantity is not lower than the safety critical electric quantity, all braking recovery energy can be supplied to the direct current converter, so that the direct current converter is supported to work. When the estimated electric quantity is lower than the safety critical electric quantity, the braking recovery energy is required to be supplied to the power battery preferentially in order to ensure that the system can normally operate, the current electric quantity of the system is increased along with the supply of the braking recovery energy, and when the estimated electric quantity calculated by the increased current electric quantity is not lower than the safety critical electric quantity, the rest braking recovery energy is supplied to the direct current converter to enable the direct current converter to work.
In one embodiment, the method comprises:
when the voltage of the storage battery is lower than a preset warning voltage, the direct current converter is controlled to start and continuously work for a preset working time, and then the direct current converter is controlled to stop working.
In the embodiment of the application, the recovered energy is possibly insufficient to ensure the work of the low-voltage system of the whole vehicle, and the system electric quantity is possibly insufficient, so that when the system uses a storage battery, the voltage of the storage battery is lower than a preset warning voltage, the power storage can cause a feeding phenomenon. In order to ensure that the storage battery cannot cause a feeding phenomenon, the direct current converter is controlled to start to work continuously for a fixed period of time, and after enough electric energy is converted from a high-voltage system to a low-voltage system through the work of the period of time, the direct current converter stops working. Although a certain battery power is required for controlling the work of the direct current converter, in order to prevent the storage battery from continuously causing the feeding phenomenon, the direct current converter is powered by a small amount of battery power, so that the direct current converter can convert more electric energy to complement the electric quantity.
