It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of an automobile signal filtering method according to an embodiment of the present invention, where this embodiment is applicable to a situation where a signal sent by a signal controller is filtered during a self-starting process of the signal controller, and the method may be executed by an automobile signal filtering apparatus, and specifically includes the following steps:
and step 110, in the self-starting process of the signal controller, when a signal sent by the signal controller is received, determining filtering information according to the signal characteristics.
Wherein, the filtering information includes but is not limited to interception time and interception digit number; signal controllers include, but are not limited to: CAN signal controller, LIN signal controller, hard wire signal controller and Ethernet signal controller. In addition to the currently used signal controller, along with the development of the automobile technology, a new signal controller may also be added to the system, for example, a reverse radar controller may be added to the system, and only the corresponding interception time and interception bit number need to be set in the filter for the reverse radar controller signal, and the whole program does not need to be adjusted.
In this embodiment, the manner of determining the filtering information according to the signal characteristics may be: and determining the filtering information corresponding to the signal according to the mapping relation.
Specifically, when the vehicle is ignited and powered on, the controllers except the vehicle controller need self-starting time, and in the time, the signal controller sends a signal to the combination instrument, wherein a filter is arranged in the combination instrument. When the filter receives the signal sent by the signal controller, the signal can be judged so as to select to allow the signal to pass or filter the signal.
Further, the filtering information may be preset in the car signal filtering system, and different signals are set respectively. For example, for a signal affecting a start-up picture of a display screen, the interception time can be set, and the signal is displayed after being delayed by corresponding time; there may be one or several bits in the signal that need to be filtered, the number of interception bits can be set for such a signal, part of the filtered signal can pass through, and the rest can pass through. When the filter receives the signal sent by the signal controller, the corresponding filtering information can be determined according to the signal characteristics, and further, what kind of operation is performed on the received signal can be determined according to the filtering information.
And step 120, performing corresponding filtering operation on the signal according to the filtering information.
In this embodiment, the manner of performing the corresponding filtering operation on the signal according to the filtering information may be: judging whether to filter the signal according to the filtering information; if not, sending the signal to a display screen for displaying; and if so, filtering the signal.
Specifically, the filter receives the signal sent by the signal controller, and can judge whether filtering is needed according to preset filtering information, and then execute corresponding operation.
In this embodiment, the manner of filtering the signal may be: filtering data corresponding to the interception digits in the signal to obtain a filtered signal; and delaying and displaying the filtered signal on a display screen according to the interception time.
Specifically, different signals can have different filtering modes, one or more bits of the signals needing to be partially intercepted can be intercepted according to set interception bits, and the signals needing to be delayed and displayed can be delayed and displayed on the display screen according to set interception time. In practical application, the interception time and the interception digit number can be adjusted in the filter according to the needs of a user.
In this embodiment, data corresponding to the interception digits in the signal is filtered, and the way of obtaining the filtered signal may be: if the number of intercepted bits includes all of the bits of the signal, the signal is deleted.
Further, the operation of filtering the signal may further include deleting the signal, and specifically, if the interception bit number in the filtering information corresponding to the signal includes all the bit numbers of the signal, the signal is deleted by the filter.
Further, the way of filtering the signal may also be: and pre-establishing a mapping relation between the signal characteristics and the filtering information.
Specifically, for each signal sent by the signal controller, the operation performed on the signal by the filter can be preset according to the characteristic, so as to establish a mapping relationship between the signal characteristic and the filtering information. After that, the filter can determine the filtering information corresponding to each received signal, and then perform the corresponding operation. When a new signal controller is added, a mapping relation between new signal characteristics and filtering information can be established without adjusting the whole program.
