Example one

Fig. 1 is a flowchart of an ignition switch state determination method provided in an embodiment of the present invention, and this embodiment is applicable to the case of ignition switch state determination, and this method may be executed by an ignition switch state determination device, which may be implemented in a form of hardware and/or software, and this ignition switch state determination device may be configured in an electronic device such as a computer, a server, a mobile terminal, and the like. As shown in fig. 1, the method includes:

and S110, acquiring an ignition hard wire signal, and determining the current switch state of an ignition switch based on the ignition hard wire signal.

The ignition hard wire signal can be a simple high-low level signal, is directly connected with a PIN (PIN) of the chip, and is generally used for basic control functions such as ignition control and the like. The ignition switch can be a switch of an ignition system (usually a key is used), a main circuit of an ignition coil can be freely opened or closed, and the ignition switch is also suitable for other electric system circuits, is commonly called a master switch, a master electric door or a master key, is a master gate for controlling a whole vehicle circuit system, and has two types of plug-in type and knob type, and is not particularly limited here.

Wherein the ignition hardwire signal may comprise: the electric power source signal ACC, the first start signal IG1, and the second start signal IG2, and the switching state of the ignition switch may include: off state LOCK gear, locked state ACC gear, ignition ON gear, START gear.

Accordingly, the current switching state is determined based on the correspondence relationship between the combination manner of the electric power source signal ACC, the first start signal IG1, and the second start signal IG2 and the switching state, and the current electric power source signal ACC, the first start signal IG1, and the second start signal IG 2.

The state of the ignition switch is directly obtained through a hard wire signal, and the quick judgment of the switch state is realized.

For example, referring to table 1, the hard-wired signal determination strategy may be to determine that the ignition switch state is LOCK gear when all three hard-wired signals, namely, the power signal ACC, the first start signal IG1, and the second start signal IG2, are 0; when the electric power signal ACC is 1, the first starting signal IG1 is 0, and the second starting signal IG2 has any value, the gear is determined as ACC gear; when the power supply signal ACC and the first starting signal IG1 are 1 and the second starting signal IG2 has any value, determining that the gear is ON; when the value of electric power signal ACC is 0 and the values of first START signal IG1 and second START signal IG2 are 1, it is determined that the START gear:

TABLE 1 ignition switch state hard line signal value truth table

Wherein, 0 is the low level state of the corresponding hard wire signal, 1 is the high level state of the corresponding hard wire signal, and X is the arbitrary level state of the corresponding hard wire signal.

It should be noted that when the vehicle is ignited, a strong current, i.e., a high level, is required, and at this time, the power supply stops supplying power, and the power supply is restarted after the ignition of the vehicle is finished, so that the hard line signal of the power supply signal ACC at the START gear is 0.

And S120, acquiring current running state data of the vehicle under the condition that the current switch state is the first state, judging the current running state data, and determining the second state.

Wherein the first state may be an ignition state ON gear. The obtaining of the current driving state data of the vehicle may be obtaining of message information of vehicle speed data and engine speed data, and correspondingly, the driving state data includes vehicle speed data and engine speed data. The second state may be an ignition switch state corresponding to the vehicle speed data and the engine speed data reaching a preset threshold.

It should be noted that, when the vehicle is in the ignition state ON gear during normal running, when a user turns a vehicle key to the START state START gear, the vehicle STARTs ignition, the engine is started, and after the engine is started, the user releases the vehicle key, and the ignition switch returns to the ignition state ON gear from the START state START gear.

Correspondingly, the vehicle speed data is judged based on the vehicle speed threshold value, and the engine rotating speed data is judged based on the rotating speed threshold value, so that a judgment result is obtained.

When the switch state is switched to the ignition state ON gear, an instrument panel ON a control screen in the vehicle can rotate, namely, the engine generates a certain rotating speed, and the problem of misjudgment of the ignition switch state due to errors is avoided by setting judgment thresholds of vehicle speed data and engine rotating speed data.

Optionally, when the current switch state is the first state, obtaining current driving state data including vehicle speed data and engine speed data, and comparing the vehicle speed data and the engine speed data with corresponding preset thresholds: and if the judgment result is that the vehicle speed data does not reach the vehicle speed threshold value and the engine rotating speed data does not reach the rotating speed threshold value, determining that the second state is a flameout ignition state.

For example, a user switches an ignition switch from a locking state ACC gear to an ignition state ON gear, a whole vehicle circuit is communicated, but an engine is only communicated through the circuit and is not ignited to start, no rotating speed data is generated, the user does not trigger an accelerator pedal, the vehicle does not start, no vehicle speed data is generated, at the moment, the vehicle speed data and the engine rotating speed data do not reach a rotating speed threshold value, and the second state of the ignition switch is determined to be a flameout ignition state, namely a flameout ON gear.

And if the judgment result is that the vehicle speed data does not reach the vehicle speed threshold value and the engine rotating speed data reaches the rotating speed threshold value, determining that the second state is the ignition state.

For example, the user switches the ignition switch from the ignition state ON gear to the starting state START gear, and manually keeps the ignition switch in the starting state START gear until the vehicle engine is successfully ignited and started, the engine generates rotation speed data after ignition and starting, the ignition switch returns to the ignition state ON gear, but the user does not trigger the accelerator pedal, the vehicle does not START, and does not generate vehicle speed data, at the moment, the vehicle speed data does not reach a vehicle speed threshold value, the engine rotation speed data reaches the rotation speed threshold value, and the second state of the ignition switch is determined to be the ignition state.

And if the judgment result is that the vehicle speed data reaches the vehicle speed threshold and the engine rotating speed data reaches the rotating speed threshold, determining that the second state is a starting ignition state, namely starting an ON gear.

For example, a user switches an ignition switch from an ignition state ON gear to a starting state START gear, and manually keeps the ignition switch in the starting state START gear until an engine of the vehicle is successfully ignited and started, after the engine is ignited and started, rotation speed data is generated, the ignition switch returns to the ignition state ON gear, the user triggers an accelerator pedal, the vehicle STARTs, vehicle speed data is generated, at the moment, the vehicle speed data and the engine rotation speed data reach rotation speed threshold values, and the second state of the ignition switch is determined to be an ignition starting state, namely a normal driving state.

The current state of the ignition switch is further determined through the driving state data of the vehicle, so that the problem that the ignition switch state is judged only through a hard wire signal to cause errors is avoided, and the ignition switch state is determined more accurately.

And S130, updating the current switch state based on the second state.

Optionally, updating the current switch state based on the second state includes: and performing OR logic processing on the current switch state and a second state to obtain a target state for updating the first state, wherein the priority of the second state is higher than that of the current switch state.

The performing or logic processing may be performing or processing on the first state and the second state when the message information of the first state and the second state are received simultaneously, and the priority of the second state is higher than the priority of the current switch state in the or processing.

Accordingly, in the case where the current switching state is the first state (i.e., the ignition state ON position), the current switching state is determined based ON the second state and the first state. The priority of the second state is higher than that of the first state, for example, if the second state is the starting state, the current switch state is determined to be the starting state, and if the second state is the ignition state, the current switch state is determined to be the ignition state.

It should be noted that, in the case where the current switch state is a state other than the first state, such as an off state, a locked state, and an on state, it is determined that the current switch state does not need to be updated by determining the second state.

Illustratively, the ignition hard wire signals are all 0, at this time, the power supply of the whole vehicle is turned off, the vehicle speed data and the engine rotating speed data are not generated, no message information is generated, the central processing unit does not receive any message information, and the current switch state of the ignition switch is determined to be the closed state LOCK gear.

The method comprises the steps of determining that the current switch state of an ignition switch is a locking state ACC gear based on an ignition hard wire signal, sending message information that the first state of the current switch state is the locking state ACC gear, turning on an accessory circuit at the moment, but not turning on an engine, still not generating vehicle speed data and engine rotating speed data, not generating message information related to the second state, enabling a central processing unit to still only receive the message information of the first state, and determining that the current switch state of the ignition switch is the locking state ACC gear based on the message information of the first state.

And determining that the current switch state of the ignition switch is an ignition state ON gear based ON the ignition hard wire signal, and sending message information that the first state of the current switch state is the ignition state ON gear, wherein the auxiliary equipment circuit and the engine are both switched ON at the moment, but the engine is not ignited and does not generate engine rotating speed data, the vehicle is not started and does not generate vehicle speed data, and the message information generating a related second state is a flameout ignition state. And the central processing unit receives the messages in the first state and the second state, performs OR logic processing on the messages in the first state and the second state according to a rule that the priority of the second state is higher than that of the current switch state, updates the first state based on the message information in the second state, and determines that the current switch state of the ignition switch is a flameout ignition state.

The method comprises the steps that the current switch state of an ignition switch is determined to be a START locking state START gear based on an ignition hard wire signal, message information that the first state of the current switch state is the START state START gear is sent, an accessory circuit and an engine are both switched on at the moment, the engine ignites to generate engine speed data, the vehicle does not START, speed data are not generated, the speed data do not reach a speed threshold, the engine speed data reach the speed threshold, and message information related to the second state is generated to be the ignition state. The central processing unit receives the messages of the first state and the second state, at the moment, the messages of the first state and the second state are subjected to OR logic processing according to a rule that the priority of the second state is higher than that of the current switch state, the first state is updated based on the message information of the second state, and the current switch state of the ignition switch is determined to be the ignition state.

After the engine is ignited and started, the ignition switch returns to an ignition state ON gear, the current switch state of the ignition switch is determined to be a locked ignition state ON gear based ON an ignition hard wire signal, message information that a first state of the current switch state is the ignition state ON gear is sent, at the moment, an accessory equipped circuit and the engine are both connected, the engine is ignited, engine rotating speed data are generated, the vehicle starts, vehicle speed data are generated, the vehicle speed data and the engine rotating speed data both reach rotating speed threshold values, message information related to a second state is generated to be a starting ignition state, and a central processing unit receives messages of the first state and the second state. And at the moment, performing OR logic processing on the messages in the first state and the second state according to a rule that the priority of the second state is higher than that of the current switch state, updating the first state based on the message information of the second state, and determining the current switch state of the ignition switch as the ignition starting state.

By setting a determination rule that the priority of the second state is higher than that of the current switch state and carrying out OR logic processing on the state of the ignition switch based on the determination rule, the occurrence of misjudgment is avoided, and the accuracy is improved.

Optionally, a switch state message is generated based on the current switch state or the updated first state, and the switch state message is transmitted to the vehicle controller domain network to be called by the controller in the vehicle.

The message information of the switch state message may be customized according to the actual situation, and is not specifically limited here. Each switch state corresponds to different message values respectively, the corresponding message values are read according to the determined current switch state, and the switch state messages are generated based on the read message values. Exemplarily, when the message value is 00, the message value is defined as a LOCK gear in a closed state; when the message value is 01, defining the message as a locking state ACC gear; when the message value is 10, defining the message value as an ignition state ON gear; when the message value is 11, defining the message value as a START state START gear; and processing other message values according to the invalidation. For example, when the current switch state is determined to be the START gear, the message value corresponding to the START gear is read, that is, 11, the switch state message with the message content of 11 is generated.

Optionally, the switch state determined by the ignition switch is stored, and the stored switch state is subjected to frequency statistics to obtain state statistical data of the ignition switch, where the state statistical data is used to evaluate the service life of the ignition switch. And performing service life evaluation of the ignition switch based on the state statistical data. In some embodiments, the statistical data of different states may be weighted to obtain comprehensive use data, and the expected service life of the ignition switch may be determined based on the corresponding relationship between the comprehensive use data and the service life. In some embodiments, the state statistics may be used as input information of an evaluation model, and the evaluation model processes the state statistics to obtain a predicted service life of the ignition switch.

The storage of the switch state determined by the ignition switch can be executed by a storage module, a memory and the like, the statistics and the evaluation of the switch state determined by the ignition switch can be executed by a central processing unit (MCU), and the ignition switch is better protected by estimating the service life of the ignition switch.

In another alternative embodiment, referring specifically to fig. 2, when only the hard-wired signal is present, the current switch state is determined based on the hard-wired signal, and it is determined whether the power supply signal ACC is 0, if the power supply signal ACC is 0, it is determined whether the second START signal IG2 is 0, if the second START signal IG2 is also 0, it is determined that the current switch state is LOCK gear, and if the second START signal IG2 is not 0, it is determined that the current switch state is START gear. If the power supply signal ACC is not 0, it is determined whether the first start signal IG1 is 0, if the first start signal IG1 is 0, it is determined that the current ON-off state is the ACC gear, and if the first start signal IG1 is not 0, it is determined that the current ON-off state is the ON gear. And generating a switch state message based on the current switch state.

If the hard wire signal and the message information of the second state are received simultaneously, the current switch state is judged based ON the hard wire signal, whether the rotating speed of the current transmitter of the vehicle reaches a threshold value is judged, if the rotating speed of the current transmitter of the vehicle reaches the threshold value, whether the current vehicle speed of the vehicle reaches the threshold value is judged, if the current vehicle speed of the vehicle also reaches the threshold value, the current switch state is judged to be an ON gear, and if the current vehicle speed of the vehicle does not reach the threshold value, the current switch state is judged to be a START gear. And if the rotating speed of the current transmitter of the vehicle does not reach the threshold value, judging that the current switch state is the ON gear. And performing OR logic processing on the current switch state and the second state based on a rule that the priority of the second state is higher than that of the current switch state, updating the target state of the first state, and generating a switch state message based on the updated first state.

It should be noted that, when the hard-wired signal is not received, the message information in the second state cannot be received, and therefore, there is no case where only the message signal in the second state is received.

According to the technical scheme, the ignition hard wire signal is obtained, the current switch state of the ignition switch is determined based on the ignition hard wire signal, the current driving state data of the vehicle is obtained under the condition that the current switch state is the first state, the current driving state data is judged, the second state is determined, and the current switch state is updated based on the second state. The accurate judgment of the current ignition switch state is realized, and the problems that the existing ignition switch state is easy to judge wrongly, the wire harness redundancy and the interface matching are complex and the like caused by the fact that each controller respectively collects signals are solved.

More specific examples of a machine-readable storage medium would include an electrical connection based on one or more wires, a portable computer diskette, a hard disk, a Random Access Memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or flash memory), an optical fiber, a compact disc read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing.

To provide for interaction with a user, the systems and techniques described here can be implemented on an electronic device having: a display device (e.g., a CRT (cathode ray tube) or LCD (liquid crystal display) monitor) for displaying information to a user; and a keyboard and a pointing device (e.g., a mouse or a trackball) by which a user can provide input to the electronic device. Other kinds of devices may also be used to provide for interaction with a user; for example, feedback provided to the user can be any form of sensory feedback (e.g., visual feedback, auditory feedback, or tactile feedback); and input from the user may be received in any form, including acoustic, speech, or tactile input.

The systems and techniques described here can be implemented in a computing system that includes a back-end component (e.g., as a data server), or that includes a middleware component (e.g., an application server), or that includes a front-end component (e.g., a user computer having a graphical user interface or a web browser through which a user can interact with an implementation of the systems and techniques described here), or any combination of such back-end, middleware, or front-end components. The components of the system can be interconnected by any form or medium of digital data communication (e.g., a communication network). Examples of communication networks include: local Area Networks (LANs), wide Area Networks (WANs), blockchain networks, and the Internet.

The computing system may include clients and servers. A client and server are generally remote from each other and typically interact through a communication network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other. The server can be a cloud server, also called a cloud computing server or a cloud host, and is a host product in a cloud computing service system, so that the defects of high management difficulty and weak service expansibility in the traditional physical host and VPS service are overcome.
