Description

Technical Field

[0001] The present disclosure relates to the technical field of vehicle control, and particularly to a vehicle control method, device, vehicle, and storage medium. Background Art

[0002] As a unit for storing and supplying electricity in an automobile, the storage battery is very important for the automobile. However, when the automobile is parked for a long time or in a non-powered-on gear state for a long time, the storage battery will have self-discharge and static power consumption, resulting in a discharged state of the storage battery, ultimately leading to problems such as the inability of the automobile to start normally and the reduction of the service life of the storage battery.

[0003] Currently, reducing the static current after the vehicle power supply is in the "OFF" gear (i.e., after the vehicle is powered off) is an important means to reduce the static loss of the storage battery. In existing vehicles, the storage battery detection unit calculates the actual state of charge of the storage battery through the ampere-hour integration + dynamic calibration + static calibration method. Among them, the ampere-hour integration method requires the storage battery detection unit to collect the discharge current and the theoretical state of charge of the storage battery in real time. When collecting the battery voltage and current in real time, it consumes the power of the storage battery, resulting in an increase in the static power consumption of the storage battery and a shortening of the vehicle parking time.

[0071] In order to more clearly understand the above objects, features and advantages of the present disclosure, the solutions of the present disclosure will be further described below. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments may be combined with each other.

[0072] Many specific details are set forth in the following description in order to fully understand the present disclosure, but the present disclosure may be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all the embodiments.

[0073] The vehicle control method, device, vehicle and storage medium provided by the embodiments of the present application are intended to solve the technical problem in the traditional technology that after the vehicle is powered off, the controller does not sleep or is often woken up during the sleep state, thereby consuming the power of the on-vehicle battery and increasing the static power consumption of the on-vehicle battery. The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below through embodiments and in conjunction with the drawings. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0074] Figure 1 is a schematic flowchart of a vehicle control method provided by an embodiment of the present disclosure. This embodiment is applicable to the situation of controlling the working state of the vehicle according to the detected discharge current and state of charge of the battery when the vehicle is in a powered-off state. The method of this embodiment can be executed by a controller in the vehicle control device. The device can be implemented in a hardware / or software manner and can be configured in the vehicle, and can implement the vehicle control method described in any embodiment of the present application.

[0075] As Figure 1 shown, the method specifically includes the following:

[0076] S10. When the vehicle is in a powered-off state, control the battery detection unit to perform a first wake-up action at a preset period.

[0077] The vehicle control method provided by the embodiments of the present disclosure controls the battery detection unit to perform a first wake-up action at a preset period when the vehicle is in a powered-off state. The preset period is, for example, 1 hour or 2 hours, that is, the battery detection unit is controlled to perform the first wake-up action every 1 hour or 2 hours. The first wake-up action is for the battery detection unit to perform self-wake-up.

[0078] Since the battery detection unit will detect the discharge current and state of charge of the battery after performing the first wake-up action, it will consume the battery power. By controlling the battery detection unit to perform the first wake-up action at a preset period, the wake-up times of the battery detection unit in the powered-off state of the vehicle are reduced, thereby reducing the static loss of the battery.

[0079] S20. Obtain the discharge current and state of charge of the battery detected by the battery detection unit in the first wake-up state.

[0080] After the battery detection unit performs the first wake-up action, the battery detection unit is woken up. At this time, the battery detection unit is in the first wake-up state. After the battery detection unit is woken up, it will detect the discharge current and state of charge of the battery, and obtain the discharge current and state of charge of the battery detected after the battery detection unit is woken up, that is, in the first wake-up state.

[0081] S30. When the discharge current meets the preset discharge current, control the working state of the vehicle according to the relationship between the state of charge and the first preset state of charge.

[0082] Optionally, when the discharge current meets the preset discharge current, controlling the working state of the vehicle according to the relationship between the state of charge and the first preset state of charge includes:

[0083] After obtaining the discharge current and state of charge of the battery detected by the battery detection unit in the first wake-up state, judge whether the discharge current of the battery meets the preset discharge current. If the discharge current of the battery is greater than the preset discharge current, that is, the discharge current of the battery is relatively large at this time. The reasons for the relatively large discharge current of the battery may be that some electrical devices in the vehicle are running in the powered-off state of the vehicle on the one hand, and some electrical devices in the vehicle may malfunction and consume the battery power in the powered-off state of the vehicle on the other hand.

[0084] To avoid excessive discharge current of the battery, which may increase the static power consumption of the battery, when the discharge current of the battery meets the preset discharge current, the working state of the vehicle is controlled according to the relationship between the state of charge (SOC) of the battery and the first preset SOC. Specifically, when the SOC of the battery is greater than or equal to the first preset SOC, the battery cell is controlled to output a first control instruction to control the information processing module in the vehicle to upload the vehicle fault information. When the SOC of the battery is less than the first preset SOC, the battery cell is controlled to output a second control instruction to control the vehicle control unit in the vehicle to send a first charging request to charge the battery.

[0085] Exemplarily, if the 20-hour discharge rate current of the battery is I 20 , and the SOC of the battery when it is fully charged is SOC, then the preset discharge current I 预设 = 10I 20 , and the first preset SOC is 60% SOC.

[0086] The vehicle control method provided by the embodiments of the present disclosure controls the battery detection unit to perform a first wake-up action at a preset period when the vehicle is in the power-off state; obtains the discharge current and SOC of the battery detected by the battery detection unit in the first wake-up state; and controls the working state of the vehicle according to the relationship between the SOC and the first preset SOC when the discharge current meets the preset discharge current. When the vehicle is in the power-off state, by controlling the battery detection unit to perform a first wake-up action at a preset period, the wake-up times of the battery detection unit in the power-off state of the vehicle are reduced, thereby reducing the static loss of the battery. When the discharge current meets the preset discharge current, the working state of the vehicle is controlled according to the relationship between the SOC and the first preset SOC, thereby reducing the static loss of the battery.

[0087] Figure 2 is a schematic flowchart of another vehicle control method provided by the embodiments of the present disclosure. This embodiment is based on the above embodiment, as Figure 2 shown, a feasible implementation manner of step S30 includes:

[0088] S31. When the discharge current meets the preset discharge current, control the battery detection unit to perform a second wake-up action according to the relationship between the SOC and the first preset SOC.

[0089] Specifically, since the battery detection unit detects the discharge current and state of charge of the battery in the first wake-up state, the duration of the first wake-up state may be only 1 s or shorter, that is, after detecting the discharge current and state of charge of the battery in the first wake-up state, the battery detection unit will enter the sleep state. When the obtained discharge current of the battery is greater than the preset discharge current, the corresponding discharge current of the battery is relatively large. To reduce the static loss of the battery, according to the relationship between the state of charge and the first preset state of charge, the battery detection unit is controlled to perform a second wake-up action, that is, the battery detection unit is controlled to perform a second self-wake-up.

[0090] S32. Control the battery detection unit to issue a control command in the second wake-up state.

[0091] S33. Control the working state of the whole vehicle according to the control command.

[0092] After the battery detection unit performs the second wake-up action, the battery detection unit is woken up. At this time, the battery detection unit is in the second wake-up state. After the battery detection unit is woken up, control the battery detection unit to issue a control command in the second wake-up state. At this time, control the working state of the whole vehicle according to the control command issued by the battery detection unit.

[0093] The vehicle control method provided by the embodiments of the present disclosure controls the battery detection unit to perform a second wake-up action according to the relationship between the state of charge and the first preset state of charge when the discharge current meets the preset discharge current, controls the battery detection unit to issue a control command in the second wake-up state, and controls the working state of the whole vehicle according to the control command, so as to control the battery detection unit to perform a second wake-up action when the discharge current is greater than the preset discharge current, enable the battery detection unit to issue a control command in the second wake-up state, and control the working state of the whole vehicle according to the control command, avoiding a large discharge current of the battery, increasing the static loss of the battery, and affecting the parking duration of the whole vehicle.

[0094] When the discharge current meets the preset discharge current, the specific process of controlling the battery detection unit to perform a second wake-up action according to the relationship between the state of charge and the first preset state of charge, and controlling the battery detection unit to issue a control command in the second wake-up state and controlling the working state of the whole vehicle according to the control command will be specifically introduced through the following embodiments.

[0095] Figure 3 It is a schematic flowchart of another vehicle control method provided by the embodiments of the present disclosure. The embodiments of the present disclosure are based on Figure 2 the corresponding embodiments, as Figure 3 described, one realizable manner of step S31 includes:

[0096] S311. When the discharge current meets the preset discharge current and the state of charge is greater than or equal to the first preset state of charge, control the battery detection unit to perform a second wake-up action for a first preset duration.

[0097] Specifically, when the discharge current of the battery is greater than the preset discharge current, according to the relationship between the state of charge and the first preset state of charge, control the duration of the second wake-up action of the battery detection unit. When the discharge current of the battery is greater than the preset discharge current and the state of charge of the battery is less than the first preset state of charge, that is, I 放电 >I 预设 , SOC 荷电 <60% SOC, at this time, control the battery detection unit to perform a second wake-up action for a first preset duration. Exemplarily, the first preset duration is 10S, that is, control the battery detection unit to remain powered on within 10S.

[0098] Corresponding to step S311, an implementable manner of step S32 includes:

[0099] S321. Control the battery detection unit to issue a first control command in the second wake-up state.

[0100] After the battery detection unit performs the second wake-up action, the battery detection unit is awakened. At this time, the battery detection unit is in the second wake-up state, and the duration of the second wake-up state is the same as the duration of the second wake-up action. That is, control the battery detection unit to supply power to the whole vehicle within 10S in the second wake-up state, and control the battery detection unit to issue a first control command in the second wake-up state.

[0101] Corresponding to step S311 and step S321, an implementable manner of step S33 includes:

[0102] S331. Upload the vehicle fault information according to the first control command.

[0103] Control the information processing module in the whole vehicle to upload the vehicle fault information according to the first control command, which is convenient for the station control personnel to receive the vehicle fault information in time and reduce the static loss of the battery. Exemplarily, the station control personnel can be the owner of the whole vehicle or the station control personnel corresponding to the vehicle brand.

[0104] Optionally, after controlling the battery detection unit to supply power to the whole vehicle in the second wake-up state and controlling the information processing module in the whole vehicle to upload the vehicle fault information, it further includes:

[0105] Control the whole vehicle to power off to further reduce the static loss of the battery.

[0106] The vehicle control method provided by an embodiment of the present disclosure controls the battery detection unit to perform a second wake-up action for a first preset duration when the discharge current meets a preset discharge current and the state of charge is less than a first preset state of charge, controls the battery detection unit to issue a control instruction in the second wake-up state, and controls the information processing module in the vehicle to upload vehicle fault information according to the first control instruction, so as to realize that when it is determined that a part of the controllers in the vehicle have a fault in the vehicle power-off state when the battery discharge current is greater than the preset current, a fault signal is reported to the station control personnel, and the battery detection unit only remains awake for the first preset duration, reducing the static power consumption of the battery detection unit.

[0107] Figure 4 It is a schematic flowchart of another vehicle control method provided by an embodiment of the present disclosure. The embodiment of the present disclosure is based on the corresponding embodiment, as Figure 2 described, another implementable manner of step S31 includes: Figure 4

[0108] S312. When the discharge current meets the preset discharge current and the state of charge is less than the first preset state of charge, control the battery detection unit to perform a second wake-up action for a second preset duration.

[0109] Specifically, when the discharge current of the battery is greater than the preset discharge current, according to the relationship between the state of charge and the first preset state of charge, control the duration of the second wake-up action of the battery detection unit. When the discharge current of the battery is greater than the preset discharge current and the state of charge of the battery is less than the first preset state of charge, that is, I 放电 >I 预设 , SOC 荷电 <60% SOC, at this time, control the battery detection unit to perform a second wake-up action for a second preset duration. Exemplarily, the second preset duration is related to the vehicle power-on duration, that is, control the battery detection unit to remain in the power-on state when the vehicle is powered on.

[0110] Corresponding to step S312, another implementable manner of step S32 includes:

[0111] S322. Control the battery detection unit to issue a second control instruction in the second wake-up state.

[0112] After the battery detection unit performs the second wake-up action, the battery detection unit is awakened. At this time, the battery detection unit is in the second wake-up state, and the duration of the second wake-up state is the same as the duration of the second wake-up action, and control the battery detection unit to issue a second control instruction in the second wake-up state.

[0113] Corresponding to steps S312 and S322, another implementable manner of step S33 includes:

[0114] S332. Send a first supplementary charging request according to the second control instruction.

[0115] Control the battery detection unit to supply power to the whole vehicle in the second wake-up state according to the second control instruction, and control the vehicle control unit in the whole vehicle to send a first supplementary charging request, thereby realizing the charging of the battery detection unit.

[0116] It should be noted that when the discharge current meets the preset discharge current and the state of charge is greater than or equal to the first preset state of charge, control the battery detection unit to perform a second wake-up action for a first preset duration. The duration of the battery detection unit in the second wake-up state is less than that when the discharge current meets the preset discharge current and the state of charge is less than the first preset state of charge, and control the battery detection unit to perform a second wake-up action for a second preset duration. The duration of the battery detection unit in the second wake-up state. Control the battery detection unit to issue a second control instruction in the second wake-up state, and control the vehicle control unit in the whole vehicle to send a first supplementary charging request according to the second control instruction, so as to realize that when it is determined that the battery discharge current is less than the preset current, control the vehicle control unit in the whole vehicle to send a first supplementary charging request to charge the battery.

[0117] Figure 5 It is a flowchart of another vehicle control method provided by the embodiments of the present disclosure. The embodiments of the present disclosure are based on Figure 4 the corresponding embodiments. As Figure 5 shown, after step S332, it further includes:

[0118] S333. Control the on-vehicle voltage unit to charge the battery according to the first supplementary charging request.

[0119] When controlling the battery detection unit to supply power to the whole vehicle in the second wake-up state and controlling the vehicle control unit in the whole vehicle to send a first supplementary charging request, at this time, the on-vehicle voltage unit charges the battery according to the first supplementary charging request, that is, when the discharge current of the battery is greater than the preset discharge current and the state of charge of the battery is less than the first preset state of charge, by controlling the battery detection unit to perform a wake-up action for a second preset duration and supplying power to the whole vehicle in the second wake-up state corresponding to the second wake-up action, the whole vehicle in the powered-on state controls the vehicle control unit to issue a first supplementary charging request after receiving the control signal, and the on-vehicle voltage unit charges the battery according to the first supplementary charging request.

[0120] S334. When the battery detection unit detects that the state of charge of the battery is the full charge state, control the whole vehicle to power off.

[0121] When the battery detection unit detects that the state of charge of the battery is the full charge state, control the whole vehicle to power off.

[0122] It should be noted that when the discharge current meets the preset discharge current and the state of charge is less than the first preset state of charge, the battery detection unit is controlled to perform a second wake-up action for a second preset duration, and the battery detection unit is controlled to supply power to the entire vehicle in the second wake-up state, and the vehicle control unit in the entire vehicle is controlled to send a first charge replenishment request. During this process, the second preset duration corresponds to the duration from when the battery detection unit performs the second wake-up action to when the entire vehicle is powered off, and the battery detection unit is in the second wake-up state between when the battery detection unit performs the second wake-up action and when the entire vehicle is powered off.

[0123] Figure 6 It is a schematic flowchart of another vehicle control method provided by an embodiment of the present disclosure. The embodiment of the present disclosure is based on the above embodiment. As Figure 6 shown, after step S20, it further includes:

[0124] S40. When the state of charge meets the second preset state of charge and the battery detection unit is in the sleep state, control the working state of the entire vehicle.

[0125] Optionally, when the state of charge is less than the second preset state of charge and the battery detection unit is in the sleep state, control the working state of the entire vehicle.

[0126] After obtaining the discharge current and state of charge of the battery detected by the battery detection unit in the first wake-up state, the battery detection unit will be powered off, that is, the battery detection unit is in the sleep state. When it is obtained that the state of charge of the battery detection unit is less than the second preset state of charge and the battery detection unit still performs a power-off action after detecting the discharge current and state of charge of the battery in the first wake-up state, at this time, the battery unit is controlled to be powered on and an electrical signal is output to the entire vehicle to supply power to the entire vehicle, and a charge replenishment request is sent through the controlled vehicle control unit to charge the battery.

[0127] It should be noted that the second preset state of charge is related to the ambient temperature of the battery. The second preset state of charge is different at different ambient temperatures. Exemplarily, when the battery is at a temperature of 25 degrees Celsius, the second preset state of charge is 25% SOC. The embodiment of the present disclosure does not specifically limit the specific value of the second preset state of charge. In a specific application scenario, the value of the second preset state of charge can be set according to the ambient temperature of the battery.

[0128] The vehicle control method provided by the embodiments of the present disclosure controls the battery detection unit to perform a first wake-up action at a preset period when the vehicle is in a power-off state; obtains the discharge current and state of charge of the battery detected by the battery detection unit in the first wake-up state; controls the working state of the vehicle when the state of charge meets the second preset state of charge and the battery detection unit is in a sleep state, so as to reduce the static loss of the battery when the state of charge of the battery is less than the second state of charge and the battery detection unit is still in a sleep state by controlling the working state of the vehicle.

[0129] Figure 7 is a schematic flowchart of another vehicle control method provided by the embodiments of the present disclosure. This embodiment is based on the Figure 6 corresponding embodiment. As Figure 7 shown, one feasible implementation of step S40 includes:

[0130] S41. When the state of charge meets the second preset state of charge and the battery detection unit is in a sleep state, control the battery detection unit to perform a third wake-up action.

[0131] Specifically, since the battery detection unit detects the discharge current and state of charge of the battery in the first wake-up state, the duration of the first wake-up state may be only 1 s or shorter, that is, the battery detection unit will enter a sleep state after detecting the discharge current and state of charge of the battery in the first wake-up state. When the obtained state of charge of the battery is less than the second preset state of charge, that is, the state of charge of the battery is less than the lowest allowable state of charge of the battery at this time, if the battery detection unit is still in a sleep state, control the battery detection unit to perform a third wake-up action, and then output an electrical signal to the vehicle to power on the vehicle.
