a switching element 1.
It should be noted that the user can send the closing signal through the switching element 1. For example, the user can operate by a key, causing the switching element 1 to transmit a closing signal.
The vehicle stall control system further includes:
a signal receiving element connected to the switching element 1, the signal receiving element receiving a turn-off signal of the switching element 1;
the state monitoring element is respectively connected with an engine controller of a vehicle and the signal receiving element, and the signal receiving element sends a first indicating signal to the state monitoring element according to the closing signal; the state monitoring element obtains state information of the engine controller according to the first indication signal;
and the judging element is respectively connected with the state monitoring element and the engine controller, receives the state information and sends a flameout indicating signal to the engine controller according to the state information.
It should be noted that the signal receiving element, the state monitoring element, and the determination element may be integrated together, for example, may be integrated in a vehicle controller of the vehicle. Here, as shown in fig. 1, the switching element 1 may transmit a turn-off signal to the signal receiving element through the first harness 3. The status monitoring element may obtain status information through the second harness 4.
In this embodiment, the signal receiving element may send the first indication signal to the status monitoring element after the user sends the off signal through the switch element, so that the status monitoring element obtains the status information of the engine controller, and thus, the determining element may determine whether to send the misfire indication signal to the engine controller and when to send the misfire indication signal by receiving the status information. That is to say, through the signal transmission among the above-mentioned each component, the vehicle controller can decide the delay time of engine shutdown according to the engine service condition (namely status information), has realized the engine stall delay function of excavator to reach the purpose of engine heat dissipation, reduced the fault rate of turbo charger, avoided causing turbo charger sintering because of excavator's engine instant shut down.
Optionally, the condition monitoring element comprises:
the timing element is respectively connected with the engine controller and the judging element, receives an electrifying signal of the engine controller, and sends working time length information of the electrified engine controller to the judging element according to the first indicating signal;
the load monitoring element is respectively connected with the engine controller and the judging element, receives load rate information of the engine sent by the engine controller, and sends the load rate information to the judging element according to the first indicating signal;
wherein the state information includes the operating duration information and the load rate information.
It should be noted that, the timing element may obtain the energization time of the engine controller by receiving an energization signal of the engine controller, so as to obtain the working time of the engine of the vehicle, specifically, obtain the working time after the engine controller is energized this time. In addition, the vehicle controller may receive load rate information of the engine transmitted from the engine controller in real time. In this way, the judging element can know the service condition of the engine according to the working duration and the load rate information, so as to determine whether the engine needs to be turned off in a delayed mode.

It should be noted that, after the dashboard receives the flameout countdown signal, the specific situation of the delayed flameout can be displayed, so that the user can know the reason and time of the delayed flameout through the dashboard. For example, the dashboard displays a countdown to delay misfire indicating how much time is left until the engine stalls. When the countdown is over, the vehicle executes a normal stall procedure, i.e. the vehicle controller sends a stall indication signal to the engine controller via the second wiring harness 4 and a power down signal to the power supply unit 2 via the third wiring harness 5. After receiving the power-off signal, the engine controller sends an oil circuit cutting-off instruction to the injection system, so that the engine stalls, and after receiving the power-off signal, the power supply element 2 can cut off a power supply path between a power supply and other elements through a power supply relay, so that the whole vehicle is shut down.

Therefore, the process of delaying the flameout of the engine can be forcibly ended under special conditions, so that the engine can be immediately flameout, and the application requirement under special scenes is met.
The following specifically exemplifies the scheme provided in the embodiments of the present application.
As an optional embodiment of the present invention, the vehicle stall control system of the present invention specifically performs the following steps when in operation:
s201: when the user operates the vehicle by the key, the switch element 1 may be caused to emit a turn-off signal through the first wire harness 3.
S202: the timing element in the vehicle controller can obtain the working time of the engine, the load monitoring element can receive the load rate information of the engine sent by the engine controller, and the judging element can calculate the average load rate of the engine according to the load rate information.
S203: the judging element can judge whether the working condition of the current engine meets the preset condition, namely, the judgment is as follows: the working time of the engine is larger than a first time threshold value, and the average load rate of the engine is larger than a preset load rate. It should be noted that the first time threshold and the preset load rate can be set according to specific situations, and in this embodiment, the first time threshold is 5 minutes, and the preset load rate is 50% as an example.
If a preset condition is met (i.e., the working time is longer than 5 minutes and the average load rate is greater than 50%), executing S204;
if not (i.e., the operating time is less than or equal to 5 minutes, or the average load rate is less than or equal to 50%), S208 is performed.
S204: entering a delayed flameout process.
S205: the dashboard may display a countdown to delay misfire.
Specifically, the vehicle controller does not send a stall indication signal to the engine controller nor a power-off signal to the power supply element 2 through the third harness 5 until the countdown is finished.
S206: when the countdown is finished, S208 is executed.
S207: the dashboard displays an operable interface for emergency shutdown, e.g., the dashboard displays a force shutdown switch, and the user performs S208 by operating (e.g., clicking) the force shutdown switch.
S208: the engine stalls.
Specifically, the vehicle controller may send a misfire indication signal to the engine controller via the second wiring harness 4 and a power-off signal to the power supply element 2 via the third wiring harness 5. After receiving the power-off signal, the engine controller sends an oil circuit cutting instruction to the injection system through the fourth wiring harness 6, so that the engine is shut down. After the power supply element 2 receives the power-off signal, a power supply path between a power supply and other elements can be cut off through a power supply relay, so that the whole vehicle is shut down.
The vehicle flameout control system provided by the embodiment of the utility model realizes the engine flameout delay function of the vehicle, can reduce the failure rate of the turbocharger, and avoids sintering of the turbocharger caused by instantaneous shutdown of the engine of the excavator.
