Detailed Description
The present application will be described in further detail with reference to the accompanying drawings, in order to make the objects, technical solutions and advantages of the present application more apparent.
The application scenario of the present application is described as follows:
In the powered-down state, the power supply and the engine of the vehicle are in a turned-off state, thereby bringing the vehicle into a dormant state. In the sleep state, the controller in the vehicle maintains the monitoring function, and by receiving the wake-up signal to wake up, the controller after wake-up is converted from the sleep state to the working state, and can be used for realizing all functions of the controller.
The vehicle provided by the embodiment of the application comprises a power battery and a low-voltage battery, wherein the power battery is used for providing energy for a power system of the electric vehicle, and the low-voltage battery is used for supplying power for low-voltage equipment of the vehicle, so that the low-voltage equipment is ensured to realize the corresponding functions. For example: when the whole vehicle is in a dormant state, the electric energy generator can be used for providing electric energy for electric appliances or equipment of the whole vehicle.
When the vehicle is in a dormant state, the low-voltage battery supplies power for electric equipment in the vehicle, so that the electric quantity of the low-voltage battery can be gradually consumed, and when the residual electric quantity of the low-voltage battery is smaller than a certain threshold value, the power battery can consume the battery electric quantity of the power battery to charge the low-voltage battery, so that the normal operation of the low-voltage equipment in the vehicle is ensured. Thus, the residual electric quantity of the power battery can be gradually reduced along with the increase of the vehicle sleep time, so that a large amount of electric energy stored in the vehicle is consumed, and the electric quantity is wasted.
To solve the above problems, an embodiment of the present application provides a vehicle energy saving control method, which is applied to a vehicle including a power battery, a low voltage battery, and a first controller, the method including:
After the vehicle is powered down, if the vehicle meets the energy-saving condition, the first controller controls the power battery and the low-voltage battery to be in a battery locking state, and the battery locking state is used for prohibiting the power battery and the low-voltage battery from discharging outwards.
In the embodiment of the application, after the vehicle is powered down, if the vehicle meets the energy-saving condition, the first controller controls the power battery and the low-voltage battery to inhibit external discharge, so that the consumption of electric equipment in the vehicle to the low-voltage battery can be reduced, and the consumption of the high-voltage battery to the power supply to the low-voltage battery is reduced, thus the consumption of electric energy stored in the vehicle is effectively reduced when the vehicle is in a powered down state for a long time.
As shown in fig. 1, an embodiment of the present application provides a control method for energy saving of a vehicle, the method being applied to the vehicle, the vehicle including a power battery, a low-voltage battery, and a first controller, the method including:
In the embodiment of the application, if the vehicle meets the energy-saving condition, the first controller controls the power battery and the low-voltage battery to be in a battery locking state. The above energy saving conditions include at least one, and the details of at least one of the energy saving conditions are described below.
In one embodiment of the present application, the energy saving conditions include: at least one of a parking time length of the vehicle in a power-down state reaches a first time length, a state of charge of the low-voltage battery is smaller than a first charge threshold value, a state of charge of the power battery is smaller than a second charge threshold value, and a first control instruction is detected, wherein the first control instruction is triggered by a user and instructs the low-voltage battery and the power battery to enter a battery power-locking state.
The following embodiments take energy-saving conditions as examples to describe various energy-saving conditions, the energy-saving conditions satisfied by the vehicle are different, and specific steps of the first controller for controlling the low-voltage battery and the power battery to be in a battery power-locking state are different, and are specifically described through steps 101-106.
Step 101, if the parking time length of the vehicle in the power-down state reaches the first time length or the detected first control instruction, the first controller generates a first energy saving instruction, and sends the first energy saving instruction to the power battery controller and the low-voltage battery controller respectively.
Wherein the first controller is any controller except a power battery controller and a low-voltage battery controller. In an embodiment of the present application, the first controller may be a vehicle body controller or a vehicle control unit.
In the embodiment of the application, the parking time of the vehicle in the power-down state can be counted by the device with the timing function on the vehicle, and the device with the timing function on the vehicle can be the vehicle-mounted communication terminal T-BOX. The parking period refers to a continuous period in which the vehicle is in a powered-down state. For example: and (3) starting to time from the last vehicle power-down time to obtain the time length from the last vehicle power-down time to the current time, wherein the time length is the parking time length of the vehicle.
When the time is counted by the device with the time counting function on the vehicle, and the parking time obtained by the time counting reaches the first time, the vehicle is still in the power-down state although the parking time is determined to meet the first time, the device with the time counting function is needed to wake up the network of the vehicle, so that the controller in the whole vehicle is waken up by the vehicle network, the vehicle is switched from the dormant state to the working state, and the first controller sends a first energy saving instruction to the power battery controller and the low-voltage battery controller respectively.
The specific process of sending the first energy saving instruction to the power battery controller and the low-voltage battery controller respectively will be described below taking the first control instruction triggered by the user and entering the battery power locking state as an example.
In the embodiment of the application, a user can trigger a first control instruction outside the vehicle through a remote control key or a button arranged on a vehicle door, and the first control instruction can be detected by the vehicle body controller, so that the first controller can be the vehicle body controller.
In order to ensure that a user having control authority over the vehicle controls the power battery and the low-voltage battery to enter a battery-locked state, it is necessary to perform security authentication on the identity of the user to determine whether the user has authority to control the vehicle. In one embodiment of the application, the second controller is used for carrying out safety authentication on the identity of the user based on the first control instruction, wherein the safety authentication is used for determining whether the user has the authority to control the vehicle; if the identity security authentication of the user passes, the second controller sends a fourth energy-saving instruction to the first controller; the first controller responds to a fourth energy-saving instruction to control the power battery and the low-voltage battery to be in a battery locking state.
Wherein the second controller may be a security authentication controller.
In the embodiment of the application, the identity security authentication of the user is to match the vehicle key of the user with the vehicle, and when the vehicle key carried by the user is matched with the vehicle, the identity security authentication of the user is considered to pass, the user is considered to have the authority to control the vehicle, and when the key carried by the user is not matched with the vehicle, the identity security authentication of the user is not passed, and the user is considered to not have the authority to control the vehicle.
It should be noted that, the security authentication of the identity of the user is used to determine whether the user has the authority to control the vehicle, and the user having the authority to control the vehicle can actively control the power battery and the low-voltage battery to be in the battery power locking state through the first control command triggered by the user.
Step 102, the power battery controller responds to the first energy saving instruction to control the power battery to enter a battery locking state and responds to the first energy saving instruction to control the low-voltage battery to enter the battery locking state.
In the embodiment of the application, the low-voltage battery controller controls the low-voltage battery to enter the battery power-locking state by controlling the MOS switch tube or the relay to disconnect the corresponding charging and discharging loop so as to inhibit the low-voltage battery from supplementing power to the low-voltage equipment in the vehicle, thereby maintaining the current electric quantity of the low-voltage battery, wherein the state is the battery power-locking state corresponding to the low-voltage battery. The power battery controller is used for controlling the relay to be disconnected so as to disconnect a circuit between the relay and the power battery and inhibit the power battery from supplementing electricity to the power battery.
It should be noted that, since the first controller is any controller other than the power battery controller and the low-voltage battery controller, and cannot directly control the power battery and the low-voltage battery, the first controller needs to control the power battery and the low-voltage battery to enter the corresponding battery power locking states respectively through the power battery controller and the low-voltage battery controller. In this case, the first controller is required to transmit a first power saving instruction to the power battery controller and the low-voltage battery controller, respectively, so that the power battery controller and the low-voltage battery control the corresponding battery to enter the corresponding battery lock state based on the first power saving instruction.
In another embodiment of the present application, when the first controller may be a power battery controller or a low-voltage battery controller, the first controller may send an energy-saving instruction to another battery controller other than the first controller, so as to control the power battery and the low-voltage battery to enter into corresponding battery lock states. The specific procedure can be seen in the following steps 103-106.
And step 103, if the state of charge of the power battery is smaller than the second charge threshold value, the first control generates a second energy-saving instruction and sends the second energy-saving instruction to the battery controller to control the power battery to enter a battery lock state.
The first controller is a power battery controller, and in the embodiment of the application, the magnitude of the second charge threshold is set according to actual conditions.
In the embodiment of the application, the power battery controller monitors the state of charge of the power battery to determine whether the state of charge of the power battery is smaller than the second charge threshold, and when the power battery controller detects that the state of charge of the power battery is smaller than the second charge threshold, the power battery controller wakes up the vehicle network to enable the vehicle to be switched from the dormant state to the working state. And in the working state, the power battery controller sends a second energy-saving instruction to the low-voltage battery controller, so that the low-voltage battery and the power battery are controlled to enter the battery power locking state respectively through the power battery controller.
And 104, the low-voltage battery controller responds to the second energy-saving instruction to control the low-voltage battery to enter a battery locking state.
In this step, the step of controlling the battery to enter the battery locking state by the battery controller may be referred to as step 102, and will not be described herein.
And 105, if the charge state of the low-voltage battery is smaller than the first charge threshold value, the first controller generates a third energy-saving instruction and sends the third energy-saving instruction to the power battery controller to control the low-voltage battery to enter a battery locking state.
The first controller is a battery controller, and in the embodiment of the present application, the first charge threshold may be set according to an actual situation.
In the embodiment of the application, the low-voltage battery controller monitors the state of charge of the low-voltage battery, so as to determine whether the state of charge of the low-voltage battery is smaller than the first charge threshold, and when the low-voltage battery controller detects that the state of charge of the low-voltage battery is smaller than the first charge threshold, the low-voltage battery controller wakes up the vehicle network to enable the vehicle to be switched from the dormant state to the working state. And in the working state, the low-voltage battery controller sends a second energy-saving instruction to the power battery controller, so that the low-voltage battery and the power battery are controlled to enter the battery locking state respectively by the low-voltage battery controller.
And step 106, the power battery controller responds to the third energy-saving instruction to control the power battery to enter a battery power locking state.
In this step, the step of controlling the battery to enter the battery locking state by the battery controller may be referred to as step 102, and will not be described herein.
When the low-voltage battery and the power battery are controlled to enter the battery power-locking state respectively, whether the functions of other low-voltage devices powered by the low-voltage battery are being used or not and whether the power battery is being used or not need to be judged, if yes, the low-voltage battery and the power battery are delayed from entering the battery power-locking state until the ongoing process is executed, and then the battery power-locking state is entered.
The steps 101-106 describe that the first controller controls the power battery and the low-voltage battery to be in the battery power locking state under the condition that different energy saving conditions are met. In order to enable a user to obtain states of a power battery and a low-voltage battery, in the embodiment of the application, if the power battery and the low-voltage battery both enter a battery power locking state, first prompt information is sent to a target terminal corresponding to a vehicle, and the first prompt information is used for indicating that the vehicle enters the battery power locking state; if one of the power battery and the low-voltage battery does not enter the battery power locking state, sending second prompt information to a target terminal corresponding to the vehicle, wherein the second prompt information is used for indicating that the vehicle fails to enter the battery power locking state.
The steps 101-106 are described above to control the power battery and the low-voltage battery to enter a battery-locked state, and the steps 107-109 are described below to illustrate the steps of exiting the battery-locked state.
And step 107, waking up the low-voltage controller based on a second control instruction triggered by the user and exiting the battery power-on state, generating a first wake-up signal by the low-voltage controller, and sending the first wake-up signal to the second controller.
It should be noted that the second control instruction is triggered by the user pressing an electronic switch on the vehicle body, where the electronic switch is a switch connected to the low-voltage controller through a hard wire, and the electronic switch on the vehicle body may be any electronic switch on the vehicle body, for example, the electronic switch may be an electronic switch on a back door, or may be a switch on a charging port cover. Because the electronic switch is connected to the low-voltage controller through a hard wire, when the electronic switch is pressed to trigger the second control instruction, the low-voltage controller can be awakened from the dormant state to the working state.
In step 108, the second controller responds to the first wake-up signal to securely authenticate the user and generate an authentication result.
It should be noted that, the process of the user security authentication may refer to the specific details in step 101, which is not described herein.
And step 109, if the authentication result is used for indicating that the identity authentication of the user is successful, the second controller controls the power battery and the low-voltage battery to exit the battery power locking state.
In the embodiment of the application, after the power battery and the low-voltage battery exit from the battery locking state, the power battery and the low-voltage battery can be recharged to the outside.
In one embodiment of the present application, the second controller controls the power battery and the low-voltage battery to exit the battery lock state, comprising:
