Technical Field
[0001] This invention relates to the field of vehicle energy-saving control technology, and in particular to a super energy-saving method, system and automobile. Background Technology
[0002] When a vehicle is parked or stored for an extended period, the overall vehicle current is relatively high, which will significantly deplete the battery's energy. If the battery drains too much power, it may become completely discharged, preventing the vehicle from starting.
[0003] There is a lack of technical solutions in the current technology for reducing the dark current of the whole vehicle to save energy.
[0004] Therefore, how to reduce the dark current consumption of the whole vehicle to meet the requirement of extending the parking time is a technical problem that needs to be solved. Summary of the Invention

[0007] Preferably, in step S2, the intelligent power distribution definition table is in shallow sleep mode. In shallow sleep mode, the power distribution status of the vehicle central control module and each electronic controller unit is power supply, and the network status is sleep.
[0008] Preferably, in step S2, the intelligent power distribution definition table is in deep sleep mode. In deep sleep mode, the network status of the vehicle central control module and each electronic controller unit is in sleep mode, and the power distribution status of the vehicle central control module, battery sensor and remote controller is in power supply mode.
[0009] Preferably, the method further includes step S3: the vehicle central control module wakes up the vehicle central control module and the electronic controller units under the vehicle BCAN network segment, ICAN network segment and PCAN network segment to start working according to the vehicle wake-up source signal accessed by the hard-wire wake-up interface or the remote specific network management message accessed by the remote controller.
[0010] Preferably, the method further includes step S4: waking up the vehicle central control module, which monitors the battery SOC power status transmitted by the battery sensor. If the battery SOC power status is lower than a predetermined threshold L1, the battery is intelligently charged. The intelligent charging means that the vehicle central control module monitors the battery power status as lower than the predetermined threshold L1 and the power battery power status as higher than the predetermined threshold H1, while the high-voltage charging system is normal, and then controls the high-voltage charging system to charge the battery.
[0011] Preferably, the wake-up of the vehicle central control module includes: waking up the vehicle central control module at a preset time, or waking up the vehicle central control module when the battery sensor has low voltage or high current, or waking up the vehicle central control module according to the vehicle wake-up source signal connected to the hard-wired wake-up interface, or waking up the vehicle central control module according to the remote specific network management message connected to the vehicle central control module by the remote controller.
[0012] Preferably, the method further includes step S5: after the vehicle central control module is woken up at a preset time, or after the battery sensor wakes up the vehicle central control module when there is low voltage or high current, the vehicle central control module only wakes up the electronic controller unit under the PCAN network segment to work.
[0013] Preferably, the method further includes step S6: After the vehicle central control module is woken up, if the vehicle central control module detects that the battery power status has been lower than the preset threshold L2 for a preset time T1 and L2 is less than L1, then the vehicle central control module will only wake up the electronic controller unit under the PCAN network segment and the remote controller under the ICAN network segment to work.

[0026] To enable those skilled in the art to better understand the technical solutions of the present invention, exemplary embodiments of the present invention are described below in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to aid understanding. These should be considered merely exemplary. Therefore, those skilled in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.
[0027] Where there is no conflict, the various embodiments of the present invention and the features thereof may be combined with each other.
[0028] As used herein, the term “and / or” includes any and all combinations of one or more related enumerated entries.
[0029] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used herein, the singular forms “a” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0033] Figure 1 This is a schematic diagram of a super energy-saving method provided in an embodiment of the present invention; as shown below. Figure 1 and Figure 5 As shown, the method includes:
[0034] Step S1: The vehicle central control module monitors vehicle signals;
[0035] Step S2: When the vehicle central control module confirms that the vehicle is in a stationary and power-off state based on the monitored vehicle signals, the vehicle central control module issues a super energy-saving mode request. The vehicle central control module configures the power distribution status and network status of each electronic controller unit according to the preset intelligent power distribution definition table, so that each electronic controller unit enters a sleep state, or the power supply of each electronic controller unit is cut off by the vehicle central control module, in order to reduce the consumption of dark current of the vehicle and extend the parking time during the long-term parking or storage period of the vehicle.
[0036] The vehicle signals include signals such as vehicle gear position, vehicle speed, power supply level, usage mode, and network status.
[0037] An electronic control unit (ECU) is used to control the driving status of a vehicle and to perform its various functions.
[0038] In some embodiments, as Figure 2 As shown, the ECU of this invention includes: an LBMS battery sensor, a DC / DC power conversion module, an HBMS power battery monitoring system, an IVI cockpit domain controller, a TBOX remote controller, a ZCU body domain controller, an ADP seat controller, a PDCU power domain controller, a HAD intelligent driving domain controller, a DKM Bluetooth master control module, and other ECUs (ECUn). Each ECU is connected to the vehicle central control module (VCM) via a CAN bus. The VCM can collect and monitor signals from each ECU and control and configure the power distribution and network status of each ECU.
[0039] In some embodiments, in step S2, the intelligent power distribution definition table is in shallow sleep mode. In shallow sleep mode, the vehicle is in a shallow sleep state, the dark current is relatively larger than in deep sleep, but the vehicle response speed is fast. In shallow sleep mode, the power distribution status of the vehicle central control module and each electronic controller unit is power supply, and the network status is sleep. The specific shallow sleep mode of the intelligent power distribution definition table is shown in Table 1-1.

[0041]
[0042] In some embodiments, in step S2, the intelligent power distribution definition table is in deep sleep mode. In deep sleep mode, the vehicle is in a deep sleep state, the dark current is very small, but the vehicle response is relatively slow. In deep sleep mode, the vehicle central control module and the network status of each electronic controller unit are in sleep mode, the power distribution status of the vehicle central control module, battery sensors, and remote controllers is powered on, and the power distribution status of the remaining electronic controller units is powered off. The specific deep sleep mode of the intelligent power distribution definition table is shown in Table 1-2.

[0044]
[0045] In some embodiments, as Figure 4 and Figure 5 As shown, it also includes step S3: The vehicle central control module wakes up the vehicle central control module and the electronic controller units under the vehicle BCAN network segment, ICAN network segment and PCAN network segment to work according to the vehicle wake-up source signal accessed by the hard-wire wake-up interface or the remote specific network management message accessed by the remote controller.

[0047] In some embodiments, as Figure 4 and Figure 5 As shown, it also includes step S4: wake up the vehicle central control module, the vehicle central control module monitors the battery SOC power status transmitted by the battery sensor, and if the battery SOC power status is lower than the predetermined threshold L1, then intelligently replenish the battery.
[0048] In some embodiments, waking up the vehicle central control module includes: waking up the vehicle central control module at a preset time, or waking up the vehicle central control module when the battery sensor has low voltage or high current, or waking up the vehicle central control module according to the vehicle wake-up source signal accessed by the hard-wired wake-up interface, or waking up the vehicle central control module according to the remote specific network management message accessed by the remote controller to the vehicle central control module.
[0049] In some embodiments, intelligent charging involves the vehicle's central control module monitoring the battery's charge level when it is below a predetermined threshold L1 and the power battery's charge level when it is above a predetermined threshold H1. If the high-voltage charging system is functioning normally, the module then controls the high-voltage charging system to charge the battery.
[0050] In some embodiments, after the vehicle central control module is woken up, if the vehicle central control module detects that the battery power status has been lower than a preset threshold L2 for a preset time T1, and L2 is less than L1, the vehicle central control module sends a low battery power reminder signal to the TBOX remote controller, and the TBOX forwards it to the cloud platform / mobile APP / SMS, etc.
[0051] In some embodiments, as Figure 4 and Figure 5 As shown, it also includes step S5: after the vehicle central control module is woken up at a preset time, or after the battery sensor wakes up the vehicle central control module when there is low voltage or high current, the vehicle central control module only wakes up the electronic controller unit under the PCAN network segment to work, while the electronic controller units under the ICAN / BCAN network segments remain in sleep mode.
[0052] In some embodiments, as Figure 4 and Figure 5 As shown, it also includes step S6: After the vehicle central control module is woken up, if the vehicle central control module detects that the battery power status has been lower than the preset threshold L2 for a preset time T1, and L2 is less than L1, then the vehicle central control module will only wake up the electronic controller unit under the PCAN network segment and the remote controller TBOX under the ICAN network segment to work, while the electronic controller units under other network segments are in a dormant state.
