Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Firstly, an application scenario of the present disclosure is explained, and the present disclosure is mainly applied to a vehicle control system, and in a possible application scenario, the vehicle control system can implement integrated control on key and tire pressure display, as shown in fig. 1, a structural block diagram of the vehicle control system is shown, as shown in fig. 1, the vehicle control system 100 includes a vehicle controller 101, and a key signal acquisition device 102 and a tire pressure signal acquisition device 103 respectively connected to the vehicle controller 101; the key signal acquisition device 102 is configured to acquire a key signal of the vehicle and send the acquired key signal to the vehicle controller 101; the tire pressure signal collecting device 103 is used for collecting the tire pressure signal of the vehicle and sending the collected tire pressure signal to the vehicle controller 101, however, the key system and the tire pressure system work differently, because the internal air pressure of the tire changes when the vehicle moves to a standstill, the tire pressure system continues to operate normally for a period of time until the air pressure of the tire reaches a cold state (the cold state is a state in which the air pressure in the tire does not change), and after reaching the cold state, the tire pressure system can also automatically detect the air pressure of the tire at preset time intervals, the key system is usually operated when the vehicle is stationary, so that, when both the tire pressure system and the key system are in operation, the key signal and the tire pressure signal interfere with each other, so that data of the two signals are partially or completely lost, and normal work of the two systems is influenced.
In order to solve the existing problems, the present disclosure provides a vehicle control method, a device, a vehicle controller and a vehicle, which first receives a key signal sent by a key signal acquisition device according to a preset signal transmission strategy; and/or receiving a tire pressure signal sent by the tire pressure signal acquisition device according to the preset signal transmission strategy, and then generating a corresponding control instruction according to the signal type of the received transmission signal, specifically, when the signal type is the tire pressure signal, if the key signal is received under the condition that the reception of the tire pressure signal is not completed, generating a tire pressure display instruction corresponding to the tire pressure signal after the reception of the tire pressure signal is completed; when the signal type is the key signal, if the tire pressure signal is received under the condition that the key signal is not received, the tire pressure display instruction corresponding to the tire pressure signal is generated after the tire pressure signal is received, so that when the key signal and the tire pressure signal interfere with each other, the tire pressure signal can be ensured to be still received, and the key signal can be continuously received after the tire pressure signal is received, so that the normal work of two systems of key signal control and tire pressure display control is not influenced.
The following description of the embodiments of the present disclosure will be made with reference to the accompanying drawings.
FIG. 2 is a flow chart illustrating a method of controlling a vehicle, as shown in FIG. 2, including the steps of:
in step 201, a transmission signal is received.
The transmission signal may include a key signal, and/or a tire pressure signal, among others.
In this step, the key signal sent by the key signal acquisition device according to a preset signal transmission strategy can be received; and/or receiving the tire pressure signal sent by the tire pressure signal acquisition device according to the preset signal transmission strategy.
In a possible application scenario, when a user presses an unlock button or a lock button on the vehicle key, or the user starts the vehicle by the vehicle key, the key signal may be received.
In addition, the tire pressure signal collecting device may include a tire pressure monitoring module, such as a tire pressure sensor, in another possible application scenario, in order to ensure driving safety, current tire pressure information of the vehicle needs to be displayed to a user through the display device in time, for example, the vehicle may detect the tire pressure of the wheel every one minute in a moving state, when the vehicle is in a moving state to a static state, the air pressure inside the wheel may change significantly, at this time, the tire pressure may also be continuously monitored according to the frequency of detecting the tire pressure every one minute, when the tire pressure does not change after the vehicle is in a static state, in order to reduce static power consumption, the tire pressure of the wheel may be detected every twenty minutes, which is only exemplified herein, the disclosure does not limit this, that is, the tire pressure signal collecting device may collect the tire pressure signal according to a preset frequency, at this time, in this step, the tire pressure signal may be received at the preset frequency, and in addition, the preset frequency is generally set higher, and the transmission frequency of the tire pressure signal is generally higher than the transmission frequency of the key signal.
It should be noted that, in consideration of practical application scenarios, usually when the user triggers the vehicle key, the key signal is received, so that the transceiving frequency of the key signal depends on the operation of the user, the key signal may also continue to be received when the user again triggers the vehicle key, either when the key signal is not received or when the reception fails, and the key system is typically operated while the vehicle is stationary, there is no particular requirement in terms of batteries, whereas the tire pressure system is operated during vehicle movement, has strict requirements on hardware, battery life, power consumption and the like, and the tire pressure of the vehicle is an important factor for judging whether the vehicle meets the driving safety condition at present, it is required to receive the tire pressure signal in time, and therefore, in the present disclosure, when the tire pressure signal and the key signal interfere with each other, the tire pressure signal may be preferentially received.
Further, when receiving the transmission signal, as long as it is ensured that at least one frame of data in one frame of data packet is completely received, the received transmission signal is an effective signal, and therefore, when the tire pressure signal and the key signal interfere with each other, in order to ensure that at least one frame of data in one tire pressure signal frame of data packet is completely received, a transmission policy for transmitting the transmission signal by the key signal transmission device and the tire pressure signal transmission device may be preset, and in this step, the preset signal transmission policy may include:
(n-1)*B2+(n-2)*B1≥A1 (1)
A2≥n*B1+(n-1)*B2-A1 (2)
wherein, a1 represents the transmission time of each frame data in the frame data packet contained in one key signal; a2 represents a frame interval time of two adjacent frames in a frame data packet contained in a key signal; b1 represents the transmission time of each frame of data in the frame data packet contained in one tire pressure signal; b2 represents the frame interval time of two adjacent frames of data in a frame data packet contained in one tire pressure signal; n represents the number of data frames in a frame data packet contained in one tire pressure signal.
The preset signaling strategy is described below with reference to fig. 3: fig. 3 is a schematic diagram of key signal frame data transmission and tire pressure signal frame data transmission, in fig. 3, a1, a2, B1, and B2 are the same as those in formulas (1) and (2), and are not repeated here, one key signal frame data packet includes more than three frames of data (in fig. 3, one key signal frame data packet includes four frames of data for example), one tire pressure signal frame data packet may include three frames of data, four frames of data, or other frames of data, which is not limited by the disclosure, but in most practical application scenarios, one tire pressure signal frame data packet generally includes three frames of data, so in fig. 3, only an example where one tire pressure signal frame data packet includes three frames of data is illustrated, after step 201 is executed, if a key signal is received even if a tire pressure signal is received, the key signal may collide with the tire pressure signal frame data at the top (i.e., the first frame in fig. 3 is the first frame of the tire pressure signal frame data packet The a1 collides with the left side of the first frame B1), and may collide with the middle of the first frame B1 (that is, the first frame a1 in fig. 3 collides with the middle of the tire pressure signal frame data packet), at this time, in order to ensure that both systems can still work normally when the two signals interfere with each other, it is necessary to set the a1, a2, B1, and B2 shown in fig. 3, so that the a1, a2, B1, and B2 satisfy the formula (1) and the formula (2), and thus, at least one frame data during signal transmission can be retained by the tire pressure, and thus, an effective tire pressure signal can be received.
In step 202, a signal type of the transmission signal is determined, the signal type comprising a tire pressure signal and/or a key signal.
In this step, the baud rate of the transmission signal may be obtained; the transmission signal includes the tire pressure signal and the key signal; and determining the signal type of the transmission signal according to the baud rate.
The baud rate represents the number of binary bits transmitted per second, which is an index for measuring the data transmission rate, so that in a possible implementation manner, the baud rate of the transmission signal can be determined by determining the number of binary bits of the transmission signal received in unit time, and because different transmission signals correspond to different signal baud rates, when the baud rate of the transmission signal is obtained, the signal type of the transmission signal can be determined according to the baud rate.
For example, assuming that the baud rate of the tire pressure signal is 6KHZ and the baud rate of the key signal is 2KHZ, when it is determined that the baud rate of the transmission signal received within the preset time period is 6KHZ, it may be determined that the signal type of the transmission signal is the tire pressure signal; when the baud rate of the transmission signal received within a preset time period is determined to be 2KHZ, determining the signal type of the transmission signal to be the key signal; when the baud rate of the transmission signal received first in the preset time period is determined to be 6KHZ and then the baud rate of the transmission signal is received to be 2KHZ, or the baud rate of the transmission signal received first in the preset time period is determined to be 2KHZ and then the baud rate of the transmission signal is received to be 6KHZ, the signal types of the transmission signal are determined to be the tire pressure signal and the key signal, it needs to be stated that when the tire pressure signal and the key signal are determined to be received simultaneously, the tire pressure signal is taken as priority, and a corresponding tire pressure display instruction is generated according to the tire pressure signal.
In step 203, when the signal type is the tire pressure signal, if the key signal is received when the reception of the tire pressure signal is not completed, a tire pressure display command corresponding to the tire pressure signal is generated after the reception of the tire pressure signal is completed.
In this step, if the key signal is received in the case where the reception of the tire pressure signal has not been completed, the key signal is an interference signal that interferes with the tire pressure signal, as described in step 201, in which case the tire pressure signal is received preferentially, and therefore, in this step, in the case where the reception of the tire pressure signal is not completed, the software execution continues to maintain the tire pressure system mode, and after the reception of the tire pressure signal is completed, the tire pressure display instruction is generated, and in addition, after step 201 is executed, the transmission time (i.e. a1, B1) of each frame of data of the received tire pressure signal and the key signal and the frame interval time (i.e. a2, B2) of two adjacent frames of data satisfy formula (1) and formula (2), in this way, if the key signal is received in a situation where the reception of the tire pressure signal is not completed, it is ensured that at least one frame of data of the tire pressure signal is completely received.
In addition, in this step, when the reception of the tire pressure signal is completed (for example, the end code in the frame data of the received tire pressure signal may be regarded as the reception of the tire pressure signal is completed), the software operating mode of the system may be switched to the operating mode of the key system, so that the key signal may be continuously received and the key control command may be generated according to the key signal.
In step 204, when the signal type is the key signal, if the tire pressure signal is received without completing the reception of the key signal, a tire pressure display command corresponding to the tire pressure signal is generated after completing the reception of the tire pressure signal.
In this step, when the signal type is the key signal, if the tire pressure signal is received when the key signal has not been received, the tire pressure signal is an interference signal that interferes with the key signal, but as described in step 201, when the key signal and the tire pressure signal interfere with each other, the tire pressure signal is received preferentially, so in this step, if the tire pressure signal is received when the key signal has not been received, the software executes to immediately switch the current key system mode to the operating mode of the tire pressure system, and after the tire pressure signal is received, the tire pressure display instruction is generated.
Likewise, in this step, when the tire pressure signal is received, the software operating mode of the system may be switched to the operating mode of the key system, so that the key signal may be continuously received and the key control command may be generated according to the key signal.
In addition, in an actual signal transmission scenario, when the signal type is the key signal, if the key signal has not been received completely, in order to avoid a false operation of switching the system operating mode when other interference signals having the same baud rate as the tire pressure signal are received, and improve the accuracy of signal identification, in one possible implementation manner, whether the tire pressure signal is received may be determined according to a preamble of the received transmission signal, and specifically, when a preset number of preambles corresponding to the tire pressure signal are continuously received, the tire pressure signal is determined to be received, so that the accuracy of signal identification is improved, and system resources are saved.
In addition, in this step, when the signal type is the key signal, if the reception of the key signal is completed, the tire pressure signal is not received, and a key control command corresponding to the key signal is generated.
Further, when the tire pressure display instruction is generated, the tire pressure display device can be controlled to display the tire pressure of the vehicle according to the tire pressure display instruction, so that a user (such as a driver or a vehicle maintenance worker) can know the current tire pressure information of the vehicle in time; when the key control command is generated, the key execution device may be controlled to respond to the key control command so as to control unlocking, locking or starting of the vehicle according to the key control command.
The tire pressure display device may include a meter display device or a vehicle liquid crystal display device, and the key execution device may include a key unlocking module, a vehicle starting module, and the like.
By adopting the method, when the key signal and the tire pressure signal are interfered with each other, the tire pressure signal can be ensured to be still received, and the key signal can be continuously received after the tire pressure signal is received, so that the normal work of the two systems of the key signal control and the tire pressure display control is not influenced.
