Embodiment Construction
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the implementation manners in the present invention, all other implementation manners obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.
[0023] Such as figure 1 As shown, the embedded vehicle system operating panel instruction reading method of the present invention comprises the following steps:
[0024] Step 1. First, define the priority of different cases. For example, when there are knob buttons and touch buttons, the priority of defining the knob buttons is higher than that of touch buttons;
[0025] Step 2. Receive the key value information from the knob button and the touch ...

The invention provides an embedded vehicle-mounted system operation panel instruction reading method and an embedded vehicle-mounted system operation panel instruction reading system. The method comprises the following steps of: performing priority definition on the cases of the operation panel; sequentially receiving key information, performing priority determination, and delay detection, if thekey value with the high priority is received again within the delay detection time, executing the next step; if yes, filtering the key value with low priority; if the key value with the high priorityis not received; if yes, recording the key value of the last time in the delay detection time; Serving as a valid key value, starting a timer;, if the key value with higher priority is not received within the time of the timer, the timer is started; if yes, transmitting the valid key value recorded for the first time to an application program for processing; and if the key value with the higher priority is received within the time of the timer, restarting timing until the time is over, and transmitting the effective key value with the higher priority to a program for processing. The method andthe system provided by the invention avoid the problem caused by misoperation of an operator, and can avoid system crash caused by repeated pressing of the key for multiple times.
Description
technical field [0001] The invention relates to the technical field of vehicle systems, in particular to a method and system for reading commands from an operation surface of an embedded vehicle system. Background technique [0002] The embedded in-vehicle system is the operating system located in the central area of the car, formerly the radio. Due to the strategic advancement of smart connected cars, large-screen in-vehicle systems have also become standard equipment for many cars. For the sake of driving safety, many hardware design manufacturers have made a choice between the extremely simple touch-screen buttons and the configuration of physical buttons on the panel. There is a high probability that the operator will touch the nearby touch buttons when operating the button knob, which will cause misoperation and cause trouble to the operator. [0003] In order to solve this problem, it is necessary to develop an operation panel instruction reading method adapted to ...
