The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The traditional internal combustion engine automobile judges whether the engine is started successfully or not by an engine controller. On the engine, there is a clear distinction between the usual rotation speed of the starter motor and the rotation speed at which the engine is fired to successfully maintain normal operation, and the engine controller usually uses this physical characteristic to design software logic to make a decision that the engine is successfully started. The engine controller monitors that the engine reaches the rotating speed for maintaining normal operation of the engine, and can judge that the engine successfully organizes a combustion process after a certain time, the running state can be continued, and the engine controller sequentially judges that the engine is successfully started. After the condition for successful engine start is fulfilled, the engine controller may switch the control state of the engine.
In the related art, for an extended range electric vehicle, a starting motor specially used for starting an engine is not usually configured, and a generator is used for dragging the engine to a certain running rotating speed, then an oil injection ignition signal is released, and the engine enters a starting process. However, the engine speed is not obviously distinguished when the engine is judged to be started or not by adopting the mode, and the engine starting success judgment logic based on the engine speed distinguishing of the traditional internal combustion engine automobile engine controller is not applicable any more. Therefore, how to better realize the vehicle starting control becomes an urgent problem to be solved.
To this end, the invention provides a vehicle start control system, a vehicle start control method, a vehicle and a computer readable storage medium.
Specifically, a vehicle start-up control system, a method, a vehicle, and a computer-readable storage medium of embodiments of the invention are described below with reference to the drawings.

That is, the first control module 110 may determine that the engine start was successful by measuring engine speed, motor torque, and the number of fuel injections based on the engine speed.
In the embodiment of the invention, when the engine speed is judged to be greater than the first threshold value, the fuel injection times are greater than the second threshold value, and the measurement result of the motor torque is smaller than the third threshold value, the engine starting success can be determined.

The first control module 110 obtains a signal collected by the sensor, and when detecting that the signal is an engine start signal, sends the engine start signal to the second control module 120 and the third control module 130.

For example, when the water temperature signal is received, it can be determined that the water temperature is greater than the preset threshold, and the water temperature signal can be detected as an engine start signal.
In an embodiment of the present invention, when the third control module 130 receives the engine start signal, it controls the motor to drive the engine to the first target rotational speed, measures the torque of the motor, and transmits the measurement results of the engine rotational speed and the motor torque to the first control module 110.
The motor controller can calculate the torque through the output voltage and the output current, and then a result of measuring the motor torque can be obtained.
The target rotation speed is defined as a rotation speed at which the engine can normally operate when the engine is operated to a certain rotation speed. Wherein, different motorcycle types, because of the engine difference, therefore the target rotational speed value also differs. For example, the engine cold start speed is not equal to 1000 and 1400 revolutions.
In an embodiment of the present invention, when the second control module 120 receives the engine start signal and detects that the engine is operated to the target speed, the second control module controls the engine to inject fuel for ignition and sends the number of times of fuel injection to the first control module 110.
That is, the first control module 110 receives the engine speed sent by the third control module 130, and based on the communication connection between the first control module 110 and the second control module 120, the first control module 110 may send the target speed to the second control module 120, so that the second control module 120 detects the target speed, and when receiving an engine start signal, controls the engine to inject fuel and ignite, and sends the number of times of fuel injection to the first control module 110, so that the first control module 110 receives the number of times of fuel injection sent by the second control module 120.
In one embodiment of the invention, the engine start success determination may be performed after the first control module 110 sends the engine start signal to the second control module 120 and the third control module 130.
According to the vehicle starting control system provided by the embodiment of the invention, the first control module is used for sending an engine starting signal to the second control module and the third control module, so that when the second control module receives the engine starting signal and detects that the engine runs to the target rotating speed, the engine is controlled to inject oil and ignite, the oil injection frequency is sent to the first control module, the third control module is used for controlling the motor to drag the engine to run to the target rotating speed when the third control module receives the engine starting signal, the motor torque is measured at the same time, the measurement results of the engine rotating speed and the motor torque are sent to the first control module, the first control module further receives the engine rotating speed, the measurement results of the motor torque and the oil injection frequency, and the engine starting success is determined according to the engine rotating speed, the measurement results of the motor torque and the oil injection frequency. And when the engine speed is judged to be greater than the first threshold, the oil injection frequency is judged to be greater than the second threshold, and the measurement result of the motor torque is judged to be less than the third threshold, the engine is determined to be started successfully. The system can determine the success of the engine starting according to the measurement results of the engine rotating speed and the motor torque and the oil injection times, and can better judge the success of the engine starting by comparing with the threshold value, thereby realizing the coordination and switching among control modules in the system.
In order to make the present invention more easily understood by those skilled in the art, the present invention further provides a vehicle start control method, fig. 3 is a flowchart of the vehicle start control method according to the embodiment of the present invention, and as shown in fig. 3, the vehicle start control method includes:

For example, various signals can be collected by various sensors, for example, collision signals can be collected by a collision sensor, rainwater signals can be collected by a rainwater sensing sensor, rotating speed signals can be collected by a wheel speed sensor, water temperature signals can be collected by a water temperature sensor, accelerator position signals can be collected by an electronic accelerator pedal position sensor, when collision signals, rainwater signals, rotating speed signals, water temperature signals and accelerator position signals are received, the received signals can be detected, when a detection signal is an engine starting signal, a motor can be controlled to drag an engine to operate to a target rotating speed, motor torque can be measured simultaneously, and when the engine is detected to operate to the target rotating speed, oil injection and ignition of the engine are controlled.
