Problems solved by technology

Under normal circumstances, the power management control strategy for the Internet of Vehicles terminal (TBOX) is very rough, and it is often a weak link in the hardware system, with many problems such as unclear status, increased power consumption, and system abnormalities. The system is the "lifeline" of the entire hardware system. Once it has a problem, it will definitely cause the collapse of the entire hardware system. Therefore, it is necessary to improve the power control strategy as much as possible.
However, there is no uniform standard for the power management strategy of the IoV terminal in the industry, and the practices of various equipment manufacturers vary widely, and it is difficult to judge which is better. However, as an important part of the control unit of the vehicle system, the IoV terminal has the advantages of its power management strategy. Inferiority is not only the impact of its own safety, but even affects the safety and energy-saving indicators of the entire vehicle system, which can be said to affect the whole body.
[0003] The working environment of the Internet of Vehicles terminal is harsh, the working conditions are complicated, and the driving habits of users are unpredictable. If the instant service is blindly provided, it will inevitably lead to too long working hours, resulting in excessive quiescent current and increased power consumption; and excessive power consumption will cause Battery loss affects user experience, so IoV terminals must enter low-power or ultra-low power mode to save power
However, in the dormant state, users often want to be able to wake up quickly. At this time, the communication module of the Internet of Vehicles terminal is not working. It must wait for the communication module to take effect, which will lead to a very long wake-up time and poor user experience.

Embodiment 1

[0027] see figure 1 , the power control method of the Internet of Vehicles terminal of the present invention, a built-in power management module in the Internet of Vehicles terminal is responsible for realizing the power-on, power-off, sleep, and wake-up functions of the vehicle-mounted functional modules, and provides reliable and low-energy for the entire system (Internet of Vehicles terminal, TBOX). Consumption voltage logic operation control strategy, the voltage logic operation control strategy is divided into three working states:

[0028] Normal: full working mode, realizing the power-on, power-off, sleep and wake-up of the on-board functional modules;

[0029] Standby: Low power consumption mode, support background GPRS wake-up, CAN wake-up;

[0030] Ultra-low power consumption mode: support background SMS wake-up, CAN wake-up, charging wake-up;

[0031] After the system (Internet of Vehicles terminal) is normally powered on, there is actually an IGN_ON (vehicle igni...

Embodiment 2

[0035] see figure 1 The difference between the power supply control method of the Internet of Vehicles terminal in this embodiment and Embodiment 1 is that the time constants for Normal to enter Standby and Standby to enter ultra-low power consumption mode can be flexibly configured according to requirements, or algorithms can be freely added / modified to help Analyze the user's behavior habits; the power-on sequence of the vehicle-mounted functional modules can also be flexibly configured to ensure that the power-on sequence is always conducive to the startup of the system (Internet of Vehicles terminal);

[0036] In the ultra-low power consumption state, when other wake-up sources except RTC meet the conditions, the system (Internet of Vehicles terminal) will start the system in the order of starting the communication module first, and then start the rest of the hardware, and enter the Normal mode; ultra-low power sleep The wake-up sources of the module are CAN (CAN bus signa...

Embodiment 3

[0038] see figure 1, the power control method of the Internet of Vehicles terminal in this embodiment differs from Embodiment 1 or Embodiment 2 in that each working mode has a pre / transition state when entering another working mode to ensure perfect Control all the state transition process; once the pre / transition state of the working mode transition is abnormal, the power management module can quickly detect the abnormality and report the abnormality through the communication module for personnel analysis; at the same time, there are self-resetting measures for the abnormal state, once detected If there is a serious abnormality, reset measures will be taken to try to repair it, so as to ensure the stability of the vehicle system;

[0039] If the reset measures cannot be resolved, the power will be turned off forcibly, and the user will be notified of the abnormality in advance on the APP, which ensures the safety of the user and avoids the battery from losing power due to the...

Abstract

The invention relates to an Internet-of-Vehicles terminal power control method. A power management module is arranged in an Internet-of-Vehicles terminal to take charge of power-on, power-off, dormancy and awakening functions of vehicle-mounted functional modules, and a reliable and low-energy-consumption voltage logic operation control strategy is provided for a whole system. The control strategyincludes three working states which are the full working mode, a low power consumption mode and an ultra-low power consumption mode. After the system is powered on, the power management module adoptsa full power-on mode to start all the vehicle-mounted functional modules and enters in a Normal mode, and a state machine monitors the working state of the system in real time; after an active dormancy signal is received, the system enters in a front / transitional state, the related functional modules are sequentially stopped according to a set sequence, after all dormancy conditions are met, thesystem enters in the low power consumption dormancy state, and an overtime detection program is started; and after the current working state meets the ultra-low power consumption dormancy condition, the system enters in the ultra-low power consumption dormancy mode, and a deep electricity saving requirement is met.
