Detailed Description
In order to more clearly describe the technical contents of the present invention, the following further description is given in conjunction with specific embodiments.
The following describes a processing method for implementing operation of multiple automobile remote control keys according to the present invention in detail with reference to the drawings, wherein the multiple automobile remote control keys are used for remotely controlling the same automobile, and the processing method is described by taking two remote control keys as an example, when a remote control receiver receives signals of two remote control keys successively. For example, when a remote control key is operated, another key is operated in a short time, the system performs arbitration based on the operated key number, and the key with the smaller key number takes priority for operation. The invention can be used for ensuring the control right of the key and improving the user control safety.
The method specifically comprises the following steps:
(1) identifying the key number of the currently operated remote control key, judging whether the currently operated remote control key is the existing key number, if so, updating the protection timing, and entering the step (2); if not, no response is made, and the processing procedure is exited;
(2) judging whether the key number of the currently operated remote control key is the same as the key number of the previously operated remote control key or not, and if so, updating the action requirement; if not, entering the step (3);
(3) judging whether the time interval of the two operations reaches the protection time, if so, updating the action requirement; if not, judging whether the key number of the currently operated remote control key is the key number of the master control key, if so, updating the action requirement, otherwise, not responding, and exiting the processing process.
In the step (2) and the step (3), after the action request is updated, the method further includes: and resetting the protection timing and recording the key number of the current operation.
Before the processing step, the key numbers of the plurality of automobile remote control keys are stored in a nonvolatile memory according to a learning sequence, usually, the remote control key (the key number with the small number) which is learned firstly is used as a master key, and the other key numbers are used as spare keys, and when a 4S vehicle is purchased, the information is informed to a client, so that the safety is enhanced and hidden dangers are eliminated when a user operates the vehicle.
As shown in fig. 1, the key number of the remote control key is stored, and the flow is as follows:
s101, during learning, comparing the currently operated remote control key with key information recorded in a nonvolatile memory, judging whether the key is a new key or not, and if not, exiting the storage process;
s102, if the currently operated key is a new key, judging whether an old key number is erased or not, and if so, directly entering S106;
s103, if not, erasing the old key number information recorded in the nonvolatile memory;
s104, initializing a key number storage area, wherein the address points to the first bit;
s105, setting an erasing completion identifier to ensure that the stored information is erased only once in a learning process;
s106, recording the key number information of the current operation in a nonvolatile memory;
and S107, pointing the key number storage area to the next position for recording the next key.
As shown in fig. 2, a flow of a processing method for operating a plurality of remote control keys is:
s201, when a remote key button is pressed and operated, the remote key sends a signal, a remote control receiver receives the signal, identifies the key number of the currently operated remote key, finds the currently operated key number from a nonvolatile memory, judges whether the currently operated key number exists, and if not, does not respond and directly exits the processing process;
s202, if the key number exists, updating an operation protection timing value;
s203, judging whether the key number of the currently operated remote control key is the same as the key number of the previously operated remote control key or not for the existing key number, and if so, directly entering S206;
s204, if the key numbers are not the same, the operation is indicated to be another key, whether the set operation protection time is exceeded is judged, and if yes, the operation enters S206;
s205, if the protection time is not exceeded, judging the size of the key number (the smaller key number is the master key), if so, entering S206, otherwise, entering S208;
s206, immediately updating the action requirement;
s207, resetting a protection timing value;
and S208, recording the current operation key number, and finishing the processing process.
In this specification, the invention has been described with reference to specific embodiments thereof. It will, however, be evident that various modifications and changes may be made thereto without departing from the broader spirit and scope of the invention. The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense.
