The invention relates to the technical field of liquid crystal display control, in particular to a thin film liquid crystal display control panel control method based on time sequence adjustment, which comprises the following steps: applying a test voltage within a frame blanking duration of a thin film liquid crystal display panel, and detecting an aging characterization voltage; determining the establishment delay duration of the output data signal relative to the gate signal; adjusting the starting pulse width of the grid signal according to the established delay duration; determining a common electrode voltage according to the starting pulse width; forming a test frame picture; detecting the response duration of the thin film liquid crystal display panel for displaying the test frame picture, and correcting the matching parameters of the establishment delay duration and the starting pulse width according to the response duration; outputting a corrected establishment delay time length and a corrected starting pulse width according to the matching parameters; and driving the thin film liquid crystal display panel to display an image. According to the invention, the image display stability is improved.

This invention provides a parking charging control method and system for plug-in hybrid heavy-duty trucks, comprising the following steps: real-time monitoring of vehicle status signals; when the vehicle status signals meet preset parking charging conditions, disabling the auxiliary braking function of the auxiliary brake switch and enabling the auxiliary brake switch to adjust parking charging parameters; acquiring the current gear signal of the auxiliary brake switch and resolving the parking charging parameters corresponding to the current gear signal according to a preset mapping relationship; controlling the engine to charge the power battery until the real-time state of charge of the power battery reaches the target state of charge. This invention reuses the vehicle's existing auxiliary brake switch, enabling the switch to switch its function when parking charging conditions are met, transforming it from an auxiliary braking control function to a parking charging parameter adjustment function, thus achieving convenient adjustment of parking charging parameters without adding additional hardware.
