Embodiment Construction

[0036] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0037] The main solution of the embodiment of the present invention is: a user connection unit sleep wake-up method, the user connection unit sleep wake-up method includes the following steps:

[0038] Real-time detection of the operating status of each module in the user connection unit, the user connection unit includes at least an MCU and a CPU;

[0039] When an abnormal state is detected, the control CPU sends a wake-up instruction to the MCU;

[0040] If the MCU has not been woken up after sending the preset number of wake-up commands, the MCU will be reset.

[0041] With the rapid development of the automobile market towards intelligence, networking, and informatization, there are more and more functions of vehicles, including wake-up and start-up of vehicles in various scenarios. After continuous updates and ...

Abstract

The invention discloses a user connection unit sleep wake-up method and device and a computer readable storage medium, the user connection unit sleep wake-up method comprises the following steps: the running state of each module in a user connection unit is detected in real time, wherein the user connection unit at least comprises an MCU and a CPU; when the abnormal state is detected, the CPU is controlled to send an awakening instruction to the MCU; and if the MCU is still not awakened after the awakening instruction is sent for a preset number of times, the MCU is reset. By implementing the method and the device, the probability of occurrence of sleep wake-up faults is reduced, the user experience is improved, a good brand image is formed, and the burden of after-sales engineers is relieved.

Description

technical field [0001] The present invention relates to the field of dormancy wake-up, in particular to a dormancy wake-up method and device for a user connection unit and a computer-readable storage medium. Background technique [0002] With the rapid development of the automobile market towards intelligence, networking, and informatization, there are more and more functions of vehicles, including wake-up and start-up of vehicles in various scenarios. After continuous updates and iterations in recent years, various wake-up and sleep functions have been gradually improved, and these sleep-wake strategies have been used in various models; however, with the continuous increase in vehicle sales, there are still very few cars that appear Sleep wake-up failure, after the analysis of the faulty parts, the fault phenomenon is the speed limit fault of the vehicle, and the instrument time does not display. Contents of the invention [0003] The main purpose of the present inventio...
