Description

Engine starting control method and device, electronic equipment and storage medium thereof

Technical Field

The present invention relates to the field of vehicle control technologies, and in particular, to an engine start control method and apparatus, an electronic device, and a storage medium thereof.

Background

Vehicle manual engine starting strategies generally allow engine starting in non-power output gears (P or N) and not in power output gears (D or R).

For hybrid transmission vehicle types with a powered motor, when an engine start is required for battery charging, the transmission needs to be set to neutral in advance to avoid unintended movement of the vehicle. A torque insufficient to move the vehicle is driven by the power motor, and a difference in rotational speed of the input shaft and the output shaft is detected. When the difference in rotational speed is less than the limit, it is considered that the neutral gear at this time still transmits torque, thereby limiting the engine start.

For the prior art scheme, detection and analysis of fault data such as electric faults, idle stop, gear shifting operation and the like and vehicle states are lacked, and the engine starting is limited by adopting simple neutral gear setting operation to avoid unexpected movement of the vehicle, so that the scheme for limiting the engine starting and stopping has the problem of lower safety.

Example 1

Fig. 1 is a flowchart of an engine start control method according to an embodiment of the present invention, which is applicable to a case where unintended movement of a vehicle is prevented, and which may be performed by an engine start control device that may be implemented in hardware and/or software, and that may be provided in an electronic device provided in a vehicle such as an engine control system, a transmission control unit, or the like. As shown in fig. 1, the method includes:

S110, during the working process of the vehicle, the judging data of the electric faults and the vehicle running state data are read, and whether the vehicle meets the transmission torque generating condition of the transmission or not is determined based on at least one of the judging data and the vehicle running state data.

The electrical fault is specifically understood as a problem that a vehicle generates transmission torque under the condition of parking gear and neutral gear due to internal factors of an electrical circuit or electrical equipment, and can include, but is not limited to, circuit short-circuit faults, solenoid valve faults, shift fork clamping faults and the like; the diagnosis and analysis of the instrument and equipment in the vehicle can be achieved through a vehicle control system, and judgment and the like can be performed through an intuitive diagnosis method. The determination data may be understood as factors that cause an electrical failure in transmitting torque, and may include, but is not limited to, main oil pressure, engine speed, individual instrument sensor signals, and the like. The running state of the vehicle refers to information describing the operating condition of the vehicle during operation, and may include, but is not limited to, vehicle speed information, brake pedal information, shift lever shift position information, driving state information, and the like. The torque is a special torque for rotating an object, the torque of the engine refers to the torque output by the engine from the crankshaft end, the torque is inversely proportional to the rotation speed of the engine under the condition that the power of the engine is fixed, and the faster the rotation speed, the smaller the torque, and the larger the torque. Transmitting torque refers specifically to converting torque into a force applied to a driven component by a mechanical transmission, wherein the driving component may include, but is not limited to, an engine. The transmission torque may be generated by a mechanical transmission by pulling the shift handle, and may be caused by an electrical fault, for example: torque transfer may also occur when an electrical fault occurs, such as a plurality of shift solenoid valves. It will be appreciated that the transmission producing a transfer torque condition may include, but is not limited to, performing a shift operation, electrical failure, etc. The shift operation that produces the transfer torque includes a non-motorized to motorized gear shift event, such as a D-N, D-P, N-P, P-N, R-N, R-P shift type, within 0-500ms after the motorized gear is shifted to the non-motorized gear.

The determination that the transmission is producing the transmission torque may specifically be a determination of whether there is an electrical fault or a shift operation that causes the transmission torque to be produced. For the factors generating the electrical faults and the electrical faults are stored in a database or a server in a one-to-one correspondence, the database can be an electrical fault list, and the fault list contains information such as electrical fault reasons, electrical fault codes, fault code setting conditions and the like. The determination of the electrical fault may be determined by looking at or traversing a list of electrical faults.

Specifically, sensor signals in each equipment are read through a control unit of the vehicle, determination data such as engine speed, gear, circuit running state, engine temperature, brake pedal information and the like and vehicle running state data are obtained, one or more of the data are analyzed and determined, and determination data and vehicle running state data of gear shifting operation causing electric faults generating transmission torque or causing transmission torque are obtained. If the control unit of the current vehicle detects a gear shifting signal fed back by the transmission control unit, as transmission torque can be generated in the transmission briefly in the gear shifting execution process, the condition that the vehicle meets the transmission torque generation condition can be determined according to the transmission torque generation condition, and otherwise, the condition is not met. And the electric fault list is checked to obtain the electric fault capable of generating the transmission torque and the electric fault reason thereof, so that whether the electric fault reason is met in the judging data is checked, and whether the transmission torque generating condition of the transmission is met is determined.

In the present embodiment, by reading the operation data of the vehicle and analyzing the determination data and the vehicle operation state data that cause the electrical failure of the transmission torque, it is found whether there is a data item satisfying the condition for the transmission to generate the transmission torque, wherein the satisfied data item may be one item or a plurality of items. These acquired data provide a data basis for the subsequent determination of electrical faults.

And S120, if the vehicle meets the condition that the transmission torque is generated by the transmission, acquiring the current gear and the engine speed of the vehicle, and determining whether the current gear and the engine speed meet the preset judging condition.

The preset determination conditions, which may include, but are not limited to, setting the gear to P or N, the engine speed being less than 20rpm, etc., may be understood, in particular, as defined settings for conditions for the transmission to produce a transmission torque, including settings for the engine speed and a shift operation, and may include, but are not limited to, settings accomplished by the transmission control unit. The current gear may be obtained by monitoring internal mechanical gear information of the transmission by the transmission control unit. The engine speed may be obtained by obtaining an engine speed signal output by an engine control system.

Specifically, when the vehicle control unit detects that a gear shifting operation exists on the vehicle, the transmission control unit starts to acquire current gear information sent by the electronic gear shifter and the rotating speed of the engine, judges whether the current gear is a P gear or an N gear, and judges whether the rotating speed of the engine is smaller than 20rmp, and if both conditions are met, the current gear and the rotating speed of the engine meet preset judging conditions.

In this embodiment, under the condition that the vehicle is judged to meet the transmission torque generation condition of the transmission, the transmission control unit is used for monitoring mechanical gear information in the transmission to obtain current gear information and engine speed, and whether the obtained information meets the preset judgment condition is judged. The judgment of the preset judgment conditions is added, and the judgment method is mainly used for judging whether the engine is allowed to start or not under the condition that the engine is in a flameout state, so that the safety of the vehicle in the driving process or the stopping process is improved.

Optionally, determining whether the current gear and the engine speed meet the preset determination conditions includes: and if the current gear is a neutral gear or a parking gear and the engine speed is smaller than a preset speed threshold, determining that the current gear and the engine speed meet a preset judging condition.

The rotational speed threshold value is specifically understood to be a rotational speed value that determines that the engine is in a flameout state. The rotational speed threshold may be determined from an experimental database. The preset rotational speed threshold is set mainly for controlling the rotational speed, and may be preset by the transmission controller, for example, 20rpm for the preset rotational speed threshold.

Specifically, it may be determined whether the current gear is a neutral or a park gear by looking at an instrument panel of the vehicle or by monitoring internal mechanical gear information of the transmission through the transmission control unit, and the engine speed is obtained through the engine control unit. If the obtained result meets that the current gear is a neutral gear or a parking gear and the rotating speed of the engine is smaller than a preset rotating speed threshold value, the current gear and the rotating speed of the engine can be determined to meet a preset judging condition.

For example, when the current gear is a neutral gear or a parking gear and the frontal rotational speed of the engine is less than the preset rotational speed threshold value of 20rpm, which is read from the determination data and the vehicle running state data that cause the transmission torque, both conditions indicating the current gear and the rotational speed of the engine satisfy the preset conditions.

And S130, if the preset judging condition is met, generating an engine start prohibition instruction, and sending the engine start prohibition instruction to the engine so as to prohibit the engine from starting.

Where the instruction refers to a command instructing the control system to perform a certain operation, the command may include, but is not limited to, a series of binary digits, a pulse signal, etc. An engine start prohibition instruction may be understood as a command that requires the engine to perform a start prohibition. The command may be generated by a transmission control unit and sent to the engine.

Specifically, when the transmission control unit determines that the vehicle satisfies the preset determination condition, an engine start prohibition instruction is generated, and the engine start prohibition instruction is transmitted to the engine through a bus transmission technology, and the engine performs start prohibition after receiving the instruction.

For example, the obtained current gear and the engine speed are matched with preset judging conditions through the transmission control unit, if the matching result is that the matching is successful, the vehicle control unit can be given to send an engine start prohibition instruction which can be generated and sent to the engine through a bus data transmission technology, and an engine brake receives the instruction and executes an engine start prohibition operation to prohibit the engine from starting.

According to the technical scheme, the judgment data of the electrical faults and the vehicle running state data are obtained for comprehensive analysis, so that whether the vehicle meets the transmission torque generating condition of the transmission is judged, whether the transmission torque generating condition is met or not is judged through detection of the gear and the engine speed, if the transmission torque generating condition is met, an engine start prohibiting instruction is generated and sent to the engine, and the engine is prohibited from being started under the condition that the electrical faults exist. By prohibiting the engine from starting in such a way, the safety problem caused by unexpected movement of the vehicle is avoided, and the safety of starting and stopping the engine is improved.

Example two

Fig. 2 is a flowchart of an engine start control method according to a second embodiment of the present invention, where the engine start control method is optimized based on the foregoing embodiment, and optionally, electrical fault determination processing is performed on determination data to obtain an electrical fault determination result; and if the electrical fault determination result is that the electrical fault exists, determining that the vehicle meets the transmission torque generating condition of the transmission. As shown in fig. 2, the method includes:

s210, during the working process of the vehicle, the judging data of the electrical faults and the running state data of the vehicle are read.

S220, performing electrical fault judgment processing on the judgment data to obtain an electrical fault judgment result.

The electrical fault determining process may be specifically understood as determining whether the obtained determination data satisfies the electrical fault list by performing the determining process through one or more of the obtained determination data and the vehicle running state data. The determination processing may be performed by a matching model or may be performed by a vehicle control unit. For example, by matching model processing, any one or more items of data can be used as input parameters, and by matching model judging processing, an electrical fault judging result can be obtained. The electrical fault determination result includes two types of results of the presence or absence of an electrical fault.

Specifically, the judging data is obtained, any item of data or a plurality of items of data are used as input parameters to be input into the matching model, the input parameters are matched with the electric fault list through the matching model, if electric fault information which accords with the input parameters is found in the electric fault list, the existence of electric faults can be determined, and otherwise, the existence of electric faults is not detected.

By way of example, any item of data or items of data in the determination data is/are matched with an electrical fault list through a matching model, for example, the normal mode display "ON" of the engine fault indicator is obtained, the inspection model display "ON" is displayed, the circuit of the idle starting control valve system is in short circuit, the electrical fault list is checked, the condition consistent with the obtained engine fault indicator is found, the circuit of the idle control valve system is in short circuit, the electrical fault of the idle control valve system is determined, and the corresponding electrical fault code is 33. If the corresponding electrical fault is matched, the existence of the electrical fault of the idle control valve system can be judged, and otherwise, the electrical fault does not exist.

In this embodiment, the electrical fault matching result is obtained by matching any one or more of the determination data with the electrical fault list. All hidden dangers generating electrical faults can be checked, and a foundation is laid for adopting corresponding measures to deal with the problems of the electrical faults.

And S230, if the electric fault judging result shows that the electric fault exists, determining that the vehicle meets the condition that the transmission torque is generated by the transmission.

Specifically, the determination that the vehicle satisfies the transmission torque generation condition of the transmission is based on determining that the electrical fault determination result is that there is an electrical fault, analyzing the electrical fault, obtaining a fault location that generates the electrical fault, and checking an electrical fault list, whether the electrical fault generates the transmission torque, and if the electrical fault causes the transmission torque to occur, determining that the vehicle satisfies the transmission torque generation condition of the transmission.

In the present embodiment, by further analyzing the portion where the electrical fault is generated on the basis of determining that the vehicle has the electrical fault, it is determined whether the fault can cause the transmission torque to be generated, and if so, it can be determined that the vehicle satisfies the transmission torque generation condition of the transmission. Through further judgment of the electrical faults, the electrical faults except the condition that transmission torque is generated by gear shifting operation are obtained, so that the detection result is more comprehensive, and an effective data basis is provided for controlling the motor.

S240, if the vehicle meets the transmission torque generating condition of the transmission, acquiring the current gear and the engine speed of the vehicle, and determining whether the current gear and the engine speed meet the preset judging condition.

S250, if the preset judging condition is met, an engine start prohibition instruction is generated, and the engine start prohibition instruction is sent to the engine so as to prohibit the engine from starting.

On the basis of the above embodiment, after determining that the electrical fault determination result is that there is an electrical fault, the method further includes: generating a disabling instruction of the idle stop state of the engine, and sending the disabling instruction of the idle stop state of the engine to the engine; the disabling instruction of the idle stop state of the engine is sent based on a first delay time period, and the starting prohibition instruction of the engine is sent based on a second delay time period, wherein the first delay time period is longer than the second delay time period.

The idle stop is a state in which the engine is automatically stopped when the vehicle stops when the vehicle idle start-stop function is in normal operation. The disabling instruction is specifically understood as a signal for controlling the idle stop of the engine not to be allowed, and the control instruction for controlling whether the idle stop of the engine can be performed may include, but is not limited to, a high-low level signal, a pulse signal, a binary character, and the like. When the engine idle stop enabling signal is set to be 'not enabled', if the engine is in an idle stop state, the engine is started; if the engine is not in the idle stop state, the idle stop of the engine is not allowed. The first delay period may be specifically understood as a period between a time when the disabling instruction of the engine idle stop state is generated and a time when the disabling instruction of the engine idle stop state is transmitted, and the second delay period may be specifically understood as a period between a time when the vehicle controller generates the engine start prohibition instruction and a time when the engine start prohibition instruction is transmitted.

For example, after determining that the electrical failure determination result is that there is an electrical failure, there is a vehicle control unit that generates a disable instruction of the idle stop state of the engine and generates an engine start prohibition instruction that requires ensuring that the engine receives the engine start prohibition instruction preferentially.

According to the technical scheme of the embodiment, when the electric fault judging result shows that the electric fault exists, the engine idle stop enabling signal is set to be 'not enabled', and the engine idle stop is not allowed. The determination meter indicates whether the gear satisfies a preset determination condition, such as that the current gear of the vehicle is P or N and the engine speed is less than an engine stop speed threshold (e.g., 20 rpm). If so, the transmission control unit transmits an engine start prohibition instruction, and performs the engine start prohibition. And, the transmission control unit transmits the engine start prohibition instruction earlier than the timing at which the idle stop enable signal is not transmitted. By the mode of prohibiting the engine from starting, unexpected movement of the vehicle caused by automatic starting of the engine due to electric faults of the electromagnetic valve in the idle stop stage can be prevented, so that accidents are prevented, and the safety of the vehicle is ensured.

Example III

Fig. 3 is a flowchart of an engine start control method according to a third embodiment of the present invention, where the engine start control method is optimized based on the foregoing embodiment, and optionally, electrical fault determination processing is performed on determination data to obtain an electrical fault determination result; if the electrical fault judging result is that the electrical fault does not exist, detecting gear shifting operation; if the detected gear shifting operation is a gear shifting operation of a preset type, determining that the vehicle meets the condition that the transmission generates transmission torque; after the detected shift operation is a shift operation of a preset type, further comprising: and determining whether the vehicle is in an idle stop state, and if so, canceling generation of an engine start prohibition instruction. As shown in fig. 3, the method includes:

s310, during the working process of the vehicle, the judging data of the electric faults and the running state data of the vehicle are read.

S320, performing electrical fault judgment processing on the judgment data to obtain an electrical fault judgment result.

And S330, if the electrical fault judging result shows that the electrical fault exists, detecting a gear shifting operation.

The detection of the gear shifting operation can be performed by reading the gear state on the instrument display, and also can be performed by gear position information sent by the transmission.

Specifically, if the vehicle control system determines that there is no electrical failure in the vehicle, execution of a shift operation on the vehicle is started, and it is checked whether a shift operation such as D-N, D-P, N-P is present.

In the embodiment, when the vehicle is determined to have no electrical fault, the judgment of the gear shifting operation is added, whether the vehicle has the gear shifting operation is obtained, and a data basis is provided for judging whether the vehicle meets the transmission torque generating condition of the transmission.

And S340, if the detected gear shifting operation is a gear shifting operation of a preset type, determining that the vehicle meets the condition that the transmission generates the transmission torque.

The preset gear shifting operation may be specifically understood as a shift from a motorized gear to a non-motorized gear, a shift from a non-motorized gear to a non-motorized gear, etc., and may include, but is not limited to, a gear shifting type such as D-N, D-P, N-P, P-N, R-N, R-P, etc.

The determination of meeting the condition of the engine transmitting torque is performed by matching the obtained determination data and the vehicle running state data with a preset type of shift operation, if the preset type of shift operation exists, the condition that the transmission generates the transmitting torque can be determined to be met, the matching process can be completed through a vehicle control system, and a matching model can be called for completion, and the method is not limited to the above.

S350, determining whether the vehicle is in an idle stop state, and if so, canceling generation of an engine start prohibition instruction.

The method comprises the steps of determining whether the vehicle is in an idle stop state or not through judging an idle start-stop state signal sent by an engine control unit, and considering that the vehicle is in the idle stop state when a signal value is in an idle stop process and an idle start process. Whether the idle stop function is on may be by detecting whether a signal at the enable end of the idle control valve system is an enable or high signal, etc.

Specifically, after it is determined that the shift operation belongs to a preset type of shift operation, an idle start-stop state signal sent by the engine control unit is acquired, and if the signal value is in the idle stop process, the idle stop process and the idle start process, it can be determined that the vehicle is in the idle stop state, and the vehicle control system cancels generation of the engine start prohibition instruction.

On the basis of the above embodiments, the present embodiment also provides a preferred example, and referring to fig. 4, fig. 4 is a schematic diagram of an engine start control method provided by the embodiment of the present invention. During operation of the vehicle, determining whether there is an associated electrical fault that can cause torque transfer within the transmission; if so, the engine idle stop enabling signal is set to be 'not enabled', and the engine idle stop is not allowed; meanwhile, judging whether the instrument displays that the current gear is the P gear or the N gear and the engine speed is less than an engine speed threshold (such as 20 rpm); if so, an engine start prohibition instruction is sent to prohibit the engine start. Secondly, judging whether a gear shifting operation which is not in an idle stop stage and can cause transmission torque exists or not under the condition that the relative electric faults which can cause the transmission torque inside the transmission are judged to exist; if so, judging whether the instrument displays that the current gear is the P gear or the N gear and the engine speed is less than the engine speed threshold (such as 20 rpm), if so, generating and sending an instruction for prohibiting the engine starting, and prohibiting the engine starting. If the judgment result of the gear shifting operation which is not in the idle stop stage and can cause the transmission torque is NO, the generation of the instruction for prohibiting the engine from starting is canceled. It should be noted that, setting the idle stop enable signal to "disable" will limit the idle stop of the engine during the period when the engine is not stopped, but will cause the engine to start automatically during the period when the engine is idle, so that the engine start prohibiting command sent by the transmission control unit should be earlier than the time point when the idle stop enable signal is sent "disable". This can prevent unexpected movement of the vehicle in the case of an idle stop because an electric failure that causes transmission torque causes the engine to automatically start.

In the present embodiment, by determining whether the vehicle has performed a preset type of shift operation and whether the vehicle is in an idle stop state for the vehicle in the case where there is no electrical failure of the vehicle, the generation of the engine start prohibition instruction is canceled in the case where the above conditions are both satisfied. The generation of the engine start prohibition instruction is canceled, so that the situation that the vehicle cannot start the engine at idle speed due to gear shifting operation after idle stop can be prevented, and the usability of the vehicle is improved on the premise of ensuring the safety of the vehicle.
