Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a vehicle combination meter initialization method, including:
and S101, continuously collecting voltage signals when the vehicle is electrified, closing the interrupt enable of each timer in the combination instrument, clearing the interrupt state identification of each timer, and initializing each timer after the interrupt state identification of all timers are cleared.
Step S102, after all the timers are initialized, judging whether the voltage signals at the moment are normal or not, if so, controlling the combination instrument to execute self-checking operation and then starting normal work; if not, controlling the combination instrument to execute self-checking operation and enter an abnormal voltage protection mode.
For step S101, when the combination meter is in a working state of normal voltage, IGN is powered off, and the meter is in a low-power consumption dormant state; the ING is electrified again, the voltage signals are continuously collected at the moment, and meanwhile before the electrification execution electrification module initializes the timer, the interruption enabling of each timer in the combination instrument is closed and the interruption state identification of each timer is cleared; after the interrupt state identifiers of all timers are cleared, initializing each timer; therefore, the problem that the subsequent timer is abnormally interrupted to generate false interruption is avoided, and the phenomenon of screen blacking is further caused.
And S102, after the initialization of the timer is finished, judging whether the voltage is normal at the moment, if so, starting normal work of the combination meter after self-checking, and finishing the initialization of the combination meter. And if the voltage is abnormal, the meter self-checks and acquires abnormal voltage at the same time, and the combination meter is controlled to enter an abnormal voltage inclusion mode to carry out abnormal voltage protection processing. The abnormal voltage signal comprises an overvoltage signal and an undervoltage signal.
In a preferred embodiment, the method further comprises the step of controlling the combination meter to perform an abnormal voltage protection mode if the abnormal voltage signal is continuously acquired within a preset time period; and the preset duration is longer than the duration of the voltage being pulled down when the vehicle is powered on. The embodiment changes the condition that the original combination instrument enters into abnormal voltage protection, in the prior art, the filtering time of power detection in the under-voltage and over-voltage protection function of the combination instrument is generally set to be 20ms, the power consumption of the whole vehicle is instantly increased at the moment of power-on to cause the voltage to be pulled down, the voltage of the whole vehicle is about 1s, namely, the voltage is continuously abnormal within 1s after the power-on, if the filtering time of power detection in the under-voltage and over-voltage protection function of the combination instrument in the prior art is 20ms, the combination instrument enters into an abnormal voltage protection mode after the power-on to cause the initialization of a timer, then the voltage of 1s is recovered to be normal, and the timer enters into one-time initialization at the moment, so that the abnormal interruption of the timer can be possibly caused, and the normal interruption operation program cannot be returned. Therefore, the preset duration of the abnormal voltage protection mode is set to be longer than the duration of the voltage being pulled down when the vehicle is electrified. This prevents the above phenomenon from occurring, and the preset time period of priority may be set to 2 s. Thereby solving the black screen problem by modifying the condition (i.e., duration) of entering the abnormal voltage protection mode.
