[0002] The ignition switch status is a very important parameter in car driving. Different controllers work in different ignition switch states. For example, the whole car is powered off in the LOCK gear, the radio works in the ACC gear, most controllers such as the instrument work in the ON gear, and the engine can only be started in the START gear. Therefore, each controller needs to judge and identify the current state of the car's ignition switch.

[0044] Embodiment 1

[0045] Figure 1 This is a flow chart of a method for determining the state of an ignition switch provided in the first embodiment of the present invention. This embodiment is applicable to the case of determining the state of an ignition switch. The method can be executed by a device for determining the state of an ignition switch. The device for determining the state of an ignition switch can be implemented in the form of hardware and / or software. The device for determining the state of an ignition switch can be configured in an electronic device such as a computer, a server, a mobile terminal, etc. Figure 1 As shown, the method includes:

[0046] S110: Acquire an ignition hard-wire signal, and determine a current switch state of the ignition switch based on the ignition hard-wire signal.

[0047] Among them, the ignition hard-wire signal can be a simple high or low level signal, directly connected to the pin (PIN) of the chip, and is generally used for basic control functions such as ignition control. The ignition switch can be the switch of the ignition system (usually using a key), which can freely open or close the main circuit of the ignition coil, and is also applicable to other electrical circuits. The ignition switch is commonly known as the main switch, the main switch or the main key. It is the main gate that controls the entire vehicle circuit system. There are two types: plug-in type and knob type, which are not specifically limited here.

[0048] Among them, the ignition hard-line signal may include: a power signal ACC, a first start signal IG1 and a second start signal IG2, and the switch state of the ignition switch may include: an off state LOCK gear, a locked state ACC gear, an ignition state ON gear, and a start state START gear.

[0049] Accordingly, the current switch state is determined based on the corresponding relationship between the combination of the power signal ACC, the first start signal IG1 and the second start signal IG2 and the switch state, and the current power signal ACC, the first start signal IG1 and the second start signal IG2.

[0050] The status of the ignition switch is directly obtained through hard-wired signals to quickly determine the switch status.

[0051] Exemplarily, referring to Table 1, the hard-wire signal judgment strategy can be that when the three hard-wire signals of the power signal ACC, the first start signal IG1, and the second start signal IG2 are all 0, the ignition switch state is determined to be the LOCK gear; when the power signal ACC is 1, the first start signal IG1 is 0, and the second start signal IG2 has an arbitrary value, it is determined to be the ACC gear; when the power signal ACC, the first start signal IG1 are 1, and the second start signal IG2 has an arbitrary value, it is determined to be the ON gear; when the power signal ACC signal value is 0, and the first start signal IG1 and the second start signal IG2 have an arbitrary value, it is determined to be the START gear:

[0052] Table 1 Ignition switch status hard-wire signal value truth table

[0053]

[0054] Among them, 0 means that the corresponding hard-wire signal is in a low level state, 1 means that the corresponding hard-wire signal is in a high level state, and X means that the corresponding hard-wire signal is in an arbitrary level state.

[0055] It should be noted that when the vehicle is ignited, a strong current, i.e. a high level, is required. At this time, the power supply stops supplying power and will resume supplying power after the vehicle ignition ends. Therefore, the hard-wire signal of the power signal ACC is 0 in the START gear.

[0056] S120: When the current switch state is the first state, obtain the current driving state data of the vehicle, determine the current driving state data, and determine the second state.

[0057] The first state may be the ignition state ON gear. Acquiring the current driving state data of the vehicle may be message information for acquiring vehicle speed data and engine speed data, and accordingly, the driving state data includes vehicle speed data and engine speed data. The second state may be the ignition switch state corresponding to the vehicle speed data and engine speed data reaching a preset threshold.

[0058] It should be noted that the vehicle is in the ignition state ON gear during normal driving. When the user turns the vehicle key to the starting state START gear, the vehicle starts to ignite and starts the engine. After the engine starts, the user releases the vehicle key and the ignition switch returns from the starting state START gear to the ignition state ON gear. Therefore, the ignition state ON gear will have several states. When the current switch state is the first state, the current driving state data of the vehicle is obtained, the current driving state data is judged, and the second state is determined.

[0059] Accordingly, the vehicle speed data is determined based on the vehicle speed threshold, and the engine speed data is determined based on the speed threshold to obtain a determination result.

[0060] When the switch state is switched to the ignition state ON position, the instrument panel on the vehicle's central control screen may rotate, that is, the engine generates a certain speed. By setting the judgment threshold of the vehicle speed data and the engine speed data, the problem of misjudgment of the ignition switch state due to errors can be avoided.

[0061] Optionally, when the current switch state is the first state, current driving state data including vehicle speed data and engine speed data is obtained, and the vehicle speed data and engine speed data are compared with corresponding preset thresholds: if the judgment result is that the vehicle speed data does not reach the vehicle speed threshold and the engine speed data does not reach the speed threshold, then the second state is determined to be the ignition off state.

[0062] Exemplarily, the user switches the ignition switch from the locked state ACC gear to the ignition state ON gear, and the entire vehicle circuit is connected, but the engine is only connected through the circuit and has not been ignited and started, and no speed data is generated. The user has not triggered the accelerator pedal, the vehicle has not started, and no vehicle speed data is generated. At this time, the vehicle speed data and the engine speed data have not reached the speed threshold, and the second state of the ignition switch is determined to be the flameout ignition state, that is, the flameout ON gear.

[0063] If the determination result is that the vehicle speed data does not reach the vehicle speed threshold, and the engine speed data reaches the speed threshold, then the second state is determined to be the ignition state.

[0064] Exemplarily, the user switches the ignition switch from the ignition state ON position to the start state START position, and manually keeps the ignition switch in the start state START position until the vehicle engine is successfully ignited and started. After the engine is ignited and started, speed data is generated. The ignition switch returns to the ignition state ON position, but the user does not trigger the accelerator pedal, the vehicle does not start, and no vehicle speed data is generated. At this time, the vehicle speed data does not reach the vehicle speed threshold, and the engine speed data reaches the speed threshold, and the second state of the ignition switch is determined to be the ignition state.

[0065] If the determination result is that the vehicle speed data reaches the vehicle speed threshold value and the engine speed data reaches the speed threshold value, then the second state is determined to be the ignition start state, that is, the ON gear is started.

[0066] Exemplarily, the user switches the ignition switch from the ignition state ON position to the start state START position, and manually keeps the ignition switch in the start state START position until the vehicle engine is successfully ignited and started. After the engine is ignited and started, speed data is generated. The ignition switch returns to the ignition state ON position, the user triggers the accelerator pedal, the vehicle starts, and vehicle speed data is generated. At this time, the vehicle speed data and the engine speed data both reach the speed threshold, and the second state of the ignition switch is determined to be the start ignition state, that is, the normal driving state.

[0067] The current state of the ignition switch is further determined through the vehicle's driving state data, avoiding the problem of errors caused by judging the ignition switch state solely through hard-wired signals, making the determination of the ignition switch state more accurate.

[0068] S130. Update the current switch state based on the second state.

[0069] Optionally, updating the current switch state based on the second state includes: performing an OR logic process on the current switch state and the second state to obtain a target state for updating the first state, wherein the priority of the second state is higher than the priority of the current switch state.

[0070] The OR logic processing may be to perform OR processing on the two when the message information of the first state and the second state are received at the same time, and the priority of the second state in the OR processing is higher than the priority of the current switch state.

[0071] Accordingly, when the current switch state is the first state (i.e., the ignition state is ON), the current switch state is determined based on the second state and the first state. The priority of the second state is higher than the priority of the first state. For example, if the second state is the start state, the current switch state is determined to be the start state, and if the second state is the ignition state, the current switch state is determined to be the ignition state.

[0072] It should be noted that, when the current switch state is other than the first state, such as the closed state, the locked state and the started state, it is determined that there is no need to update the current switch state by determining the second state.

[0073] Exemplarily, the ignition hard-wire signals are all 0, the power of the entire vehicle is turned off, no vehicle speed data and engine speed data are generated, no message information is generated, the central processing unit does not receive any message information, and determines that the current switch state of the ignition switch is the off state LOCK gear.

[0074] Based on the ignition hard-wire signal, it is determined that the current switch state of the ignition switch is the locked state ACC gear and a message information is sent that the first state of the current switch state is the locked state ACC gear. At this time, the accessory equipment circuit is connected, but the engine is not connected, and the vehicle speed data and engine speed data are still not generated, and the message information related to the second state is not generated. The central processing unit can still only receive the message information of the first state, and based on the message information of the first state, it is determined that the current switch state of the ignition switch is the locked state ACC gear.

[0075] Based on the ignition hard-wire signal, the current switch state of the ignition switch is determined to be the ignition state ON gear and a message information is sent that the first state of the current switch state is the ignition state ON gear. At this time, the auxiliary equipment circuit and the engine are connected, but the engine is not ignited, and no engine speed data is generated. The vehicle has not started, and no vehicle speed data is generated. The message information of the related second state is the flameout ignition state. The central processing unit receives the message of the first state and the second state. At this time, the message of the first state and the second state is processed by logic or according to the rule that the priority of the second state is higher than the priority 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 flameout ignition state.

[0076] Based on the ignition hard-wire signal, the current switch state of the ignition switch is determined to be the locked start state START gear and the message information that the first state of the current switch state is the start state START gear is sent. At this time, the auxiliary equipment circuit and the engine are connected, the engine is ignited, and the engine speed data is generated, but the vehicle has not started, and the vehicle speed data is not generated. The vehicle speed data does not reach the vehicle speed threshold, and the engine speed data reaches the speed threshold, and the message information of the related second state is generated as the ignition state. The central processing unit receives the messages of the first state and the second state. At this time, the messages of the first state and the second state are processed by OR logic according to the rule that the priority of the second state is higher than the priority of the current switch state, and 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.

[0077] After the engine is ignited and started, the ignition switch returns to the ignition state ON gear. Based on the ignition hard-wire signal, the current switch state of the ignition switch is determined to be the locked ignition state ON gear and a message is sent indicating that the first state of the current switch state is the ignition state ON gear. At this time, the auxiliary equipment circuit and the engine are all connected, the engine is ignited, and the engine speed data is generated. The vehicle starts and the vehicle speed data is generated. The vehicle speed data and the engine speed data both reach the speed threshold, and the message information of the related second state is generated as the start ignition state. The central processing unit receives the messages of the first state and the second state. At this time, the messages of the first state and the second state are processed by OR logic according to the rule that the priority of the second state is higher than the priority 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 start ignition state.

[0078] By setting a determination rule that the priority of the second state is higher than the priority of the current switch state, and performing OR logic processing on the state of the ignition switch based on the second state, misjudgment is avoided and accuracy is improved.

[0079] Optionally, based on the current switch state or the updated first state, a switch state message is generated, and the switch state message is transmitted to the vehicle controller area network to be called by a controller in the vehicle.

[0080] Among them, the message information of the switch status message can be customized according to the actual situation, and no specific limitation is made here. Each switch state corresponds to a different message value. According to the determined current switch state, the corresponding message value is read, and the switch status message is generated based on the read message value. Exemplarily, when the message value is 00, it is defined as the closed state LOCK gear; when the message value is 01, it is defined as the locked state ACC gear; when the message value is 10, it is defined as the ignition state ON gear; when the message value is 11, it is defined as the start state START gear; other message values ​​are treated as invalid. For example, when it is determined that the current switch state is the START gear, the message value corresponding to the START gear is read, that is, 11, and a switch status message with a message content of 11 is generated.

[0081] Optionally, the switch state determined by the ignition switch is stored, and the frequency statistics of the stored switch states are counted to obtain state statistics of the ignition switch, and the state statistics are used to evaluate the service life of the ignition switch. The service life of the ignition switch is evaluated based on the state statistics. In some embodiments, statistical data of different states may be weighted to obtain comprehensive usage data, and the estimated service life of the ignition switch may be determined based on the corresponding relationship between the comprehensive usage data and the service life. In some embodiments, the state statistics may be used as input information of the evaluation model, and the estimated service life of the ignition switch may be obtained after being processed by the evaluation model.

[0082] Among them, the storage of the switch state determined by the ignition switch can be performed by a storage module, a memory, etc., and the statistics and evaluation of the switch state determined by the ignition switch can be performed by the central processing unit MCU. By estimating the life of the ignition switch, the ignition switch can be better protected.

[0083] In another optional embodiment, see Figure 2 , when only the hard-wire signal exists, the current switch state is judged based on the hard-wire signal, and it is determined whether the power signal ACC is 0. If the power 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. If the second start signal IG2 is not 0, it is determined that the current switch state is START gear. If the power 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 switch state is ACC gear. If the first start signal IG1 is not 0 either, it is determined that the current switch state is ON gear. A switch state message is generated based on the current switch state.

[0084] If the hard-wire signal and the second state message information are received at the same time, while judging the current switch state based on the hard-wire signal, it is judged whether the current vehicle engine speed reaches the threshold. If the current vehicle engine speed reaches the threshold, it is judged whether the current vehicle speed reaches the threshold. If the current vehicle speed also reaches the threshold, it is judged that the current switch state is ON gear. If the current vehicle speed does not reach the threshold, it is judged that the current switch state is START gear. If the current vehicle engine speed does not reach the threshold, it is judged that the current switch state is ON gear. Based on the rule that the priority of the second state is higher than the priority of the current switch state, the current switch state and the second state are subjected to OR logic processing, the target state of the first state is updated, and the switch state message is generated based on the updated first state.

[0085] It should be noted that when the hard-line signal is not received, the message information of the second state cannot be received. Therefore, there is no situation where only the message signal of the second state is received.

[0086] The technical solution of this embodiment obtains the ignition hard-wire signal, determines the current switch state of the ignition switch based on the ignition hard-wire signal, obtains the current driving state data of the vehicle when the current switch state is the first state, determines the current driving state data, determines the second state, and updates the current switch state based on the second state. Accurate judgment of the current ignition switch state is achieved, solving the problems of easy misjudgment of the existing ignition switch state, wiring harness redundancy caused by each controller collecting signals separately, and complex interface matching.
