Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
In a first aspect, an embodiment of the present invention provides a vehicle automatic light-off control method.
FIG. 1 is a flow chart of a method for controlling automatic light-off of a vehicle according to an embodiment of the invention;
referring to fig. 1, in one embodiment, the vehicle automatic light-off control method includes the steps of:
s11, detecting the charging condition of a storage battery, the gear state of a light combination switch and the gear state of a low-voltage power supply;
in this embodiment, the battery is used for supplying power for the car light, if the car light is in the state of lighting always, under the condition that does not need the lamp source, can cause the energy extravagant, can reduce the life of car light moreover. Because the storage battery is not charged, the voltage of the storage battery is reduced when the car lamp is always on, and the working current of the big lamp is increased to maintain the power in order to maintain the brightness of the big lamp, so that the big lamp is overheated and even burnt. The car light works for a long time, and does not supplement electricity for the storage battery, and the feeding risk of the storage battery is increased, if the storage battery feeds electricity, when the vehicle is started again, the vehicle cannot be started and cannot run due to insufficient electric quantity of the storage battery, and therefore the vehicle breaks down.
Alternatively, for a fuel vehicle, the charge condition of the battery may be detected by detecting whether the generator is started, and if the generator is not started, the battery is not in a charged state. For the new energy vehicle, the charging condition of the storage battery may be detected by detecting whether DCDC (high voltage conversion low voltage converter for converting the high voltage of the power battery to the low voltage of the storage battery) is operated, and if DCDC is not operated, the storage battery is not in a charged state.
The light combination switch is a device for controlling the illumination light and the signal light. In an embodiment, the vehicle lamp capable of being controlled by the light combination switch includes a position light, a low beam light, a high beam light and a fog light, and the gear of the light combination switch includes a position light gear, a low beam light gear, a high beam light gear and a fog light gear, which are respectively used for controlling the vehicle lamps with the same name. The fog lamp shield can control the fog lamp only when the far-reaching headlamp shield is turned on.
The gear state of the low-voltage power supply corresponds to the gear state of the ignition switch, and the gear of the low-voltage power supply comprises an ON gear, an ACC gear and an OFF gear. When the ON gear is also called an ON gear and the low-voltage power supply is in the ON gear, the whole vehicle circuit is connected, the system can perform necessary preparation work and self-checking work for starting the engine or the motor, and the low-voltage power supply can be kept at the position when the vehicle runs normally. The ACC gear is also called an accessory power-on gear, when the power supply is in the ACC gear, the accessory circuit is connected, and the equipment such as a CD, an air conditioner, a radio and the like can be used. The OFF gear is also called LOCK gear or LOCK stop, when the low voltage power supply is in the OFF gear, the circuit is completely closed except the anti-theft system and the small lamp in the vehicle, and the steering wheel is locked. For the fuel oil vehicle, the gear of the low-voltage power supply also comprises a START gear, the START gear is also called a START gear, when a key is screwed to the START gear, a starter circuit is connected, so that an engine is driven to run and START, and the key automatically returns to an ON gear after the key is loosened.
Alternatively, for a vehicle provided with a key, the gear state of the low-voltage power supply may be detected by the key rotation position. For a keyless vehicle, a vehicle body controller controls the gear of the low-voltage power supply according to the vehicle state, for example, when a vehicle door is unlocked, the gear of the low-voltage power supply is switched to an ACC gear, and when a driver enters the vehicle and steps ON a brake, the gear of the low-voltage power supply is switched to an ON gear, and the gear state of the low-voltage power supply can be detected by the vehicle body controller.
S12, if the storage battery is not in a charging state and the light combination switch is not in an OFF gear, starting an automatic light-OFF function;
in this embodiment, if the storage battery is not in a charging state, that is, the fuel vehicle generator is not started or the new energy vehicle DCDC is not operated, and the light combination switch is not in an OFF gear, that is, the light combination switch is in a position light gear, a low beam light gear or a far OFF light gear, the automatic light-OFF function is turned on. It can be understood that when the storage battery is in a charging state, the storage battery is charged, so that feeding of the storage battery or burning of the car lamp can not be caused. Under the premise of not considering energy waste and service life reduction of the car lamp, the automatic light-off function is not required to be started when the storage battery is in a charging state. If the automatic light-off function is in an on state and certain judging conditions are met, the light is controlled to be turned off, so that the situation that the light is continuously turned on when the storage battery is not charged, energy waste, power supply of the storage battery, service life reduction of the light and even burning are avoided.
It should be noted that, step S12 may be configured to be triggered by a preset frequency or based on a specific action. Specifically, step S12 is configured to detect whether the current state satisfies the on condition that the battery is not in the charged state and the light combination switch is not in the OFF gear at regular intervals when the predetermined frequency is triggered, and step S12 is configured to detect whether the current state satisfies the on condition if a specific action (for example, switching the low-voltage power supply gear, switching the light combination switch gear, etc.) is detected when the specific action is triggered. If the signal is satisfied, the automatic light-off function is started, and if the signal is not satisfied, the automatic light-off function is stopped.
S13, determining a light-off judging time length according to a gear state of the low-voltage power supply;
in this embodiment, different low-voltage power supply gear states correspond to different user use conditions, different user use conditions correspond to different light source demand degrees, and the light-off judging duration can be met as far as possible before automatic light-off according to the gear states of the low-voltage power supply, so that the influence of light-off on user experience when the user needs the light source is avoided. For example, when the low-voltage power supply is in an ON state, the user's demand level for the light source is highest, the maximum light-OFF judging time period can be correspondingly set, when the low-voltage power supply is in an ACC state, the user's demand level for the light source is medium, the medium light-OFF judging time period can be correspondingly set, when the low-voltage power supply is in an OFF state, the user's demand level for the light source is lowest, and the minimum light-OFF judging time period can be correspondingly set.
Fig. 2 is a schematic flow chart showing step S13 in the vehicle automatic light-off control method shown in fig. 1.
Referring to fig. 2, in an embodiment, step S13 includes:
s131, if the low-voltage power supply is in an ON gear, determining that the light-off judging time period is a first preset time period; and/or
And S132, if the low-voltage power supply is in the ACC gear, determining the light-off judging time length as a second preset time length.
With continued reference to fig. 2, in one embodiment, step S13 includes:
s133, if the low-voltage power supply is in an OFF gear and the driving vehicle door is in an open state, determining the light-OFF judging duration as a third judging duration;
if the low-voltage power supply is in the OFF gear and the driving vehicle door is in the closed state, determining the light-OFF judging duration as a fourth judging duration,
the fourth judging time period is smaller than the third judging time period.
In this embodiment, when the low-voltage power supply is in the OFF gear, the state of the driver can be further determined by driving the state of the vehicle door (typically, the left front door), so that the light source demand of the user can be more accurately evaluated. Specifically, if the driving vehicle door is in an open state under the premise that the low-voltage power supply is in an OFF gear, it is indicated that a driver needs to enter the vehicle, the light source requirement is relatively high, and a long light-OFF judging time period is correspondingly set. If the vehicle door of the driving position is in a closed state, the driver is not required to enter the vehicle temporarily, the light source requirement is relatively low, and a short light-off judging time period is correspondingly set.
It should be noted that, if step S13 includes step S131, step S132, and step S133 at the same time, the first preset duration, the second preset duration, the third preset duration, and the fourth preset duration decrease sequentially. For example, the first preset time period may be set to 30 minutes, the second preset time period may be set to 20 minutes, the third preset time period may be set to 10 minutes, and the fourth preset time period may be set to 15 seconds.
And S14, if the automatic light-off function is in an on state and the lighting time length of the vehicle lamp is longer than or equal to the light-off judging time length, the vehicle lamp is turned off.
In this embodiment, after the automatic light-off function is turned on and the light-off judging duration is determined, if the light-on duration of the vehicle lamp reaches the light-off judging duration, the vehicle lamp is judged to have satisfied the light source requirement of the user, so that the vehicle lamp is turned off, thereby avoiding the continuous turn-on of the vehicle lamp when the storage battery is not charged, causing energy waste, power supply of the storage battery, and reduction or even burning of the service life of the vehicle lamp.
Therefore, in the embodiment, the charging condition of the storage battery, the gear state of the light combination switch and the gear state of the low-voltage power supply are detected; if the storage battery is not in a charging state and the light combination switch is not in an OFF gear, the automatic light-OFF function is started; determining a light-off judging time length according to the gear state of the low-voltage power supply; if the automatic light-off function is in an on state and the lighting time length of the vehicle lamp is longer than or equal to the light-off judging time length, the vehicle lamp is turned off. Through this embodiment, whether judge whether need to turn on the automatic function of turning on light according to whether the battery is in the state of charge to avoid the battery to charge when the car light continuously turn on, cause the energy extravagant, battery feed, car light life reduces even burns out. And determining the light-off judging time according to the gear state of the low-voltage power supply, and considering the requirement degree of a user on the light source under different conditions, thereby improving the user experience.
Fig. 3 is a schematic flow chart of a method for controlling automatic light-off of a vehicle according to another embodiment of the invention.
Referring to fig. 3, in one embodiment, the vehicle auto light-off control method includes the steps of:
s21, detecting the charging condition of a storage battery, the gear state of a light combination switch and the gear state of a low-voltage power supply;
s22, if the storage battery is not in a charging state and the light combination switch is not in an OFF gear, starting an automatic light-OFF function;
in this embodiment, the analysis of step S21 and step S22 may refer to the analysis of step S11 and step S12 in the foregoing embodiment, and will not be described herein.
S23, if the automatic light-off function is in an on state and the electric quantity of the storage battery is lower than the preset electric quantity or the voltage of the storage battery is lower than the preset voltage, turning off the vehicle lamp;
in this embodiment, even if the lighting duration of the vehicle lamp does not reach the light-off judging duration, the vehicle lamp is controlled to be turned off as long as the electric quantity of the storage battery is detected to be too low, so that the feeding risk of the storage battery is further reduced. Alternatively, for a vehicle provided with the battery charge sensor, the lamp is turned off when the charge of the battery is lower than a preset charge, and for a vehicle not provided with the battery charge sensor, the lamp is turned off when the voltage of the battery is lower than a preset voltage. For example, the preset charge may be set to 20% and the preset voltage may be set to 9.5 volts. Optionally, before the car lamp is turned off, a light-off prompt can be output to inform the user that the light is about to be turned off to save electricity, for example, a popup window prompts that the light is about to be turned off to save electricity, and an audible alarm prompt. If the user still does not turn off the car lamp or inputs an instruction for keeping the lamp on after reminding, the car lamp is automatically turned off after the time delay is preset. The preset time delay period is, for example, 2 minutes.
S24, determining a light-off judging time length according to the gear state of the low-voltage power supply;
in this embodiment, the analysis of step S24 may refer to the analysis of step S13 in the previous embodiment, and will not be described herein.
S25, determining reminding judging time according to the light-off judging time, wherein the reminding judging time is smaller than the light-off judging time;
if the automatic light-off function is in an on state and the lighting time length of the car light is longer than or equal to the reminding judging time length, outputting a light-off reminding;
in this embodiment, when the lighting duration of the lamp approaches the light-off judging duration, a light-off prompt is output to inform the user that the lamp is about to be turned off so as to save electric quantity, and if the user still does not turn off the lamp after prompt or inputs an instruction for keeping the lamp on, the lamp is automatically turned off when the lighting duration of the lamp reaches the light-off judging duration. Therefore, the user reaction time can be reserved before the lamp is turned off, the influence of the light-off on the user experience when the user needs the light source is avoided, and the user experience is further improved. Further, the reminding judging time length is a light-off judging time length minus a preset time length interval. The preset time interval is, for example, 2 minutes.
S26, if the automatic light-off function is in an on state and the lighting time length of the vehicle lamp is longer than or equal to the light-off judging time length, the vehicle lamp is turned off.
In this embodiment, the analysis of step S26 may refer to the analysis of step S14 in the previous embodiment, and will not be described herein.
In one embodiment, after step S13 or step S24, the method further includes:
if the automatic light-off function is in an on state and the gear state of the low-voltage power supply is changed, returning to the step of determining the light-off judging time length according to the gear state of the low-voltage power supply, and turning on the car light and recalculating the light-on time length of the car light.
In this embodiment, if the gear state of the low-voltage power supply changes, it is determined that the requirement of the user for the light source also changes, so that it is necessary to determine the light-off determination duration according to the new gear state of the low-voltage power supply. If the preceding lamp is turned off, the lamp is turned on again and the lighting time period is calculated after the lamp is turned on. If the front car lamp is not turned off, the lighting time length is directly recalculated.
Further, if the automatic light-OFF function is in an on state, the low-voltage power supply is in an OFF state, and the state (on state or OFF state) of the driving vehicle door is changed, the step of determining the light-OFF judging time period according to the gear state of the low-voltage power supply is performed again, and the vehicle lamp is turned on and the light-on time period of the vehicle lamp is recalculated.
After step S13 or step S24, the method further comprises:
if the automatic light-off function is in an on state and the gear state of the light combination switch is changed, the vehicle lamp is lightened, and the lighting time of the vehicle lamp is recalculated.
In this embodiment, if the gear state of the light combination switch changes, the corresponding vehicle lamp is turned on according to the new gear state of the light combination switch, and the turn-on duration of the vehicle lamp is recalculated.
After step S13 or step S24, the method further comprises:
if the automatic light-off function is in an on state and the vehicle is in an anti-theft state, the vehicle lamp is turned on and the lighting time of the vehicle lamp is recalculated.
In this embodiment, after the low voltage power supply is in the OFF gear, the doors are closed, and the whole vehicle is armed, the vehicle enters an anti-theft state. According to the previous analysis, the lamp will be extinguished in a very short time. And if the anti-theft state is released again, the extinguished car lamp is re-lighted and the lighting time of the car lamp is re-calculated, so that the driver can get on the car conveniently.
In one embodiment, after step S12 or step S22, the method further includes:
if the automatic light-off function is in an ON state, the low-voltage power supply is in an ON state, and the power system is in an active state, the automatic light-off function is turned off.
In this embodiment, when the power source is in the ON range and the powertrain is in the active state, it indicates that the vehicle is traveling. The light is critical to ensuring the running safety when the vehicle runs, and the light should not be turned off automatically. Therefore, in order to secure driving safety, the auto-turn-off function needs to be turned off. Alternatively, for a fuel-fired vehicle, the powertrain is in an activated state if the engine is started. For the new energy vehicle, if the whole vehicle power system works, the power system is in an activated state.
In addition, since the battery is normally in a charged state when the vehicle is running, the auto-light-off function is not activated. However, the power generation system failure may cause a situation in which the battery cannot be charged while the vehicle is running, in which case the automatic light-off function is turned on by the on determination condition in step S12 or step S22. At this time, besides turning off the automatic light-off function, a fault alarm can be further output to inform the driver of the power generation system fault so as to take countermeasures in time.
Fig. 4 is a flowchart showing a vehicle automatic light-off control method in an embodiment of the invention.
Referring to fig. 4, in an embodiment, if the battery is not in a charged state (for the fuel vehicle generator is not started, for the new energy vehicle DCDC is not operated), and the light combination switch is not in an OFF gear, the automatic light-OFF function is turned on. When the automatic turn-off function is turned on, if the battery power is low (if a battery power sensor is provided, the battery power is lower than 20%, and if the battery power sensor is not provided, the battery voltage is lower than 9.5 v), the automatic turn-off function is performed.
When the automatic light-off function is started, if the low-voltage power supply is in an ON gear, when the lighting time of the car lamp reaches 28 minutes, a popup window ON an instrument panel is used for reminding that the lamp light is turned off so as to save the electric quantity, and an audible alarm is given. If the user does not turn off the lamp within 2 minutes after reminding, the lamp is automatically turned off when the lighting time reaches 30 minutes. When the automatic light-off function is started, if the power supply is in ACC gear, when the lighting time of the car lamp reaches 18 minutes, a popup window on an instrument panel is used for reminding that the lamp light is turned off so as to save the electric quantity, and an audible alarm is given. If the user does not turn off the lamp within 2 minutes after reminding, the lamp is automatically turned off when the lighting duration reaches 20 minutes.
