Detailed Description
In addition, the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Fig. 1 is a flowchart of a vehicle power saving method according to an embodiment of the present invention. As shown in fig. 1, the vehicle is controlled by at least one smart key button, and the vehicle power saving method includes:
step S11, detecting the signal of at least one intelligent key;
and step S12, when the signal of the at least one intelligent key is the first combination of the preset key signals, controlling the vehicle to enter a low power consumption mode under the condition that the engine of the vehicle is not started.
In the embodiment of the invention, when the vehicle is started and is not started, if an operator such as a vehicle owner or a driver of a transport vehicle wants to make certain power-consuming functions not work, the vehicle can detect the combination of signals of the intelligent key keys by the combined operation of the intelligent key keys, if the combination of the signals of the intelligent key keys is a first combination of preset key signals (such as sequential combination of unlocking, locking, unlocking and locking, but not limited to the above, any sequential combination of the intelligent key keys can be selected, such as locking, vehicle searching, unlocking, locking and the like, but needs to be configured in advance, and the condition that the combination of the signals of the keys entering the low power consumption mode needs to be finally finished by taking a whole vehicle locking signal as a finishing condition) is judged that the vehicle owner has a desire to actively request the vehicle to enter the low power consumption mode, and then a control signal is sent to inform a corresponding module to enter the low power consumption, so that the corresponding function of the corresponding module is not operated any more, and the electric quantity of the storage battery is stopped being consumed.
Fig. 2 is a flowchart of a vehicle power saving method according to another embodiment of the present invention. As shown in fig. 2, the method includes:
step S21, setting a function of allowing entry into a low power consumption mode according to an external input;
step S22, detecting the signal of at least one intelligent key;
and step S23, when the signal of the at least one intelligent key is the first combination of the preset key signals, controlling the vehicle to enter a low power consumption mode under the condition that the engine of the vehicle is not started.
Since there are many functions that consume electric power even when the engine of the vehicle is not started, in the embodiment of the present invention, the vehicle may further be provided with a function that allows entry into the low power consumption mode according to an external input. Therefore, an operator such as a vehicle owner or a driver of the transport vehicle can select the function to be in the low power consumption mode through the display screen on the instrument desk, and the corresponding function can be smoothly stopped when the low power consumption mode is entered only if the low power consumption mode authorization of the corresponding function is started. For a function that an operator such as a vehicle owner or a driver of a transport vehicle does not want to enter the low power consumption mode, the function is continuously maintained even if the entire vehicle enters the low power consumption mode. In addition, the vehicle can be controlled to enter the low power consumption mode directly through a display screen on an instrument desk besides the combination of signals of the intelligent key buttons is used for controlling the vehicle to enter the low power consumption mode.
The functions that may enter the low power mode may include: the PKE/RKE unlocking function of the PEPS, the static monitoring function of the TPMS, the detection function of the space below the back door, the state detection function of a back door microswitch, a combined headlamp, a welcome lamp, a windscreen wiper, a windscreen washing function and the like, and the functions are characterized in that the electric quantity of a storage battery is still consumed when a vehicle is idle.
When the vehicle enters a low power consumption mode, light prompting can be carried out, such as normally lighting for a period of time, or horn prompting sound or short text prompting of a combination instrument and the like.
The embodiment of the invention preferably needs to be controlled by using the combination of the signals of the intelligent key press each time the low-power consumption mode is entered. However, for convenience, the owner of the vehicle may select (e.g., via the dashboard) that the vehicle enters the low power mode after the vehicle is controlled to enter the low power mode using a combination of signals from the fob key once, and then the vehicle automatically enters the low power mode after each time the engine of the vehicle is turned off for a certain period of time.
In addition, in the embodiment of the invention, the vehicle power saving method can be used only as a truck driver to transport the vehicle to a 4S store without opening the vehicle owner, so that the setting of selecting the function of entering the low power consumption mode on the instrument desk is not involved, and the complexity of the system can be further simplified.
Fig. 3 is a flowchart of a vehicle power saving method according to another embodiment of the present invention. As shown in fig. 3, the method includes:
step S31, detecting the signal of at least one intelligent key;
step S32, judging whether the signal of at least one intelligent key is the first combination of the preset key signal;
step S33, when the signal of the at least one intelligent key is the first combination of the preset key signals, the vehicle is controlled to enter a low power consumption mode under the condition that the vehicle engine is not started;
step S34, judging whether the signal of at least one intelligent key is the second combination of the preset key signal;
and step S35, when the signal of the at least one intelligent key is the second combination of the preset key signals, controlling the vehicle to exit the low power consumption mode.
In addition, in the embodiment of the invention, in addition to the method for controlling the vehicle to enter the low power consumption mode described above, the vehicle may be controlled to exit the low power consumption mode. For example, when the vehicle detects that the signal of the at least one smart key is the second combination of the preset key signals, the vehicle can be controlled to exit the low power consumption mode. The second combination of the preset key signals may be an unlocking signal, a locking signal, and an unlocking signal in sequence, but is not limited thereto, and any combination different from any combination in sequence of the smart key keys entering the low power consumption mode may be used, but the configuration needs to be performed in advance, and a condition that the combination of the signals of the keys exiting the low power consumption mode finally needs to take the vehicle unlocking signal as the end needs to be satisfied). When the vehicle receives the second combination of the preset key signals needing to exit the low power consumption mode, the combination instrument carries out state prompt at the moment, informs a user that the vehicle is still in the low power consumption mode, and inquires the vehicle owner whether the vehicle owner determines that the vehicle needs to exit the mode.
If it is forgotten to use the combination of key signals to control the vehicle to exit the low power mode, the non-execution of some functions in the low power mode may cause inconvenience and even danger, and thus the low power mode may be exited if the vehicle is still in the low power mode while the engine of the vehicle is started. When the vehicle exits the low power consumption mode, similar to the vehicle entering the low power consumption mode, the light prompt can be performed, such as flashing for a certain number of times, or a horn prompt tone or a short text prompt of a combination instrument and the like.
By the invention, when a vehicle owner has an idle vehicle idea or before a truck driver transports the vehicle, the vehicle can actively and timely enter a low power consumption mode through simple operation, and the consumption of the electric quantity of the storage battery is further reduced. Experiments prove that when the function enters the degradation mode, the static current of 3-9mA can be saved. Compared with a vehicle without the function, the whole vehicle can be promoted by about 1/3 in idle time on the premise of not influencing the function of the whole vehicle. That is, a vehicle which needs to be charged with a storage battery after more than 20 days is transported, and the function can be applied for about 30 days.
Fig. 4 is a schematic structural diagram of a vehicle power saving device according to an embodiment of the present invention. As shown in fig. 4, the vehicle is controlled by at least one smart key button, and the vehicle power saving device includes: the device comprises a detection unit 1 and a control unit 2, wherein the detection unit 1 is used for detecting a signal of at least one intelligent key; the control unit 2 is configured to control the vehicle to enter a low power consumption mode when the engine of the vehicle is not started when the signal of the at least one key fob key is a first combination of preset key signals (such as, but not limited to, an unlock signal, a lock signal, an unlock signal, and a lock signal).
Since there are many functions that can enter the low power consumption mode, such as the PKE/RKE unlocking function of the PEPS, the static monitoring function of the TPMS, the detection function of the space below the back door, the state detection function of the back door microswitch, the combination headlight, the usher lamp, the wiper, and the windshield washing function, etc., the owner sometimes does not want all the functions to enter the low power consumption mode, in the embodiment of the present invention, the control unit 2 may further set a function that allows the low power consumption mode to be entered according to an external input, such as a function that needs to enter the low power consumption mode to be selected through a display screen located on the dashboard.
After the vehicle enters the low power consumption mode, the embodiment of the present invention further provides a manner of exiting the low power consumption mode, for example, the control unit 2 may further control the vehicle to exit the low power consumption mode when the signal of the at least one smart key is a second combination of the preset key signals (for example, but not limited to, an unlock signal, and an unlock signal), or when the vehicle engine is started.
The specific embodiment of the vehicle power saving device is similar to the embodiment of the vehicle power saving method, and redundant description is omitted here.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
