[0040] To reduce the starting frequency of the hybrid vehicle engine and thus reduce the occurrence frequency of sudden increases in vehicle noise, the present application provides an engine start control method for a hybrid vehicle.

[0041] Figure 1 Shows a flowchart of the engine start control method for a hybrid vehicle provided by the present application. The exemplary execution subject of this method is the vehicle main control unit VCU (Vehicle Control Unit) of the hybrid vehicle. Refer to Figure 1 , this method includes:

[0042] Step S110: Monitor in real time whether the vehicle's battery is in a low power state. If it is detected that the battery is in a low power state, then detect whether the vehicle is in a parked state.

[0043] Step S120: When it is detected that the vehicle is in a parked state, if it is detected that the counter is equal to the initialized initial value, the timer starts timing until the timer exceeds a preset duration threshold, then start the engine to supply electrical energy to the battery, and increase the value of the counter.

[0044] Step S130: When it is detected that the vehicle is in a parked state, if it is detected that the counter is greater than the initial value, start the engine to supply electrical energy to the battery.

[0045] It should be noted that hybrid vehicles mainly drive the vehicle through the battery. Therefore, in order to ensure the vehicle's endurance, it is necessary to supplement electrical energy to the battery when the battery is in a low power state to avoid battery power loss. Therefore, in the embodiments of the present application, the vehicle's battery is monitored in real time whether it is in a low power state to determine whether the battery needs to be supplemented with electrical energy.

[0046] Specifically, if it is detected that the battery is not in a low power state, it means that the battery does not need to be supplemented with electrical energy temporarily. On the contrary, if it is detected that the battery is in a low power state, it means that the battery needs to be supplemented with electrical energy.

[0047] Furthermore, it should be noted that compared with starting the engine when the vehicle is driving normally, starting the engine when the vehicle is parked will cause more prominent noise and will more easily have an adverse impact on the driver's driving experience. Specifically, compared with the in-vehicle background noise when driving normally, the in-vehicle background noise when parked is usually lower, which results in the engine start noise being more prominent when the vehicle is parked even when starting the engine. Moreover, according to the driver's usual driving experience, the interior of the vehicle should be quieter when parked. Therefore, the more prominent engine start noise when the vehicle is parked will conflict with the driver's driving experience, thus having an adverse impact on the driver's driving experience. Especially when the vehicle is parked for a short time (for example: briefly parked due to waiting for a traffic light), frequent starting of the engine will have a further adverse impact on the driver's driving experience.

[0048] In order to reduce the frequency of starting the engine when the vehicle is parked for a short time, after detecting that the battery is in a low power state, detect whether the vehicle is in a parked state.

[0049] When it is detected that the vehicle is in a parked state, it is further detected whether a counter preset for the parked state is equal to an initialized initial value. If it is detected that the counter is equal to the initial value, it indicates that the vehicle first enters the parked state when in a low battery state, and there is basically no risk of battery power loss in a short period of time. Therefore, the engine does not need to be started within a short period of time after the vehicle first enters the parked state. Therefore, if it is detected that the counter is equal to the initial value, the timer starts timing. Before the timer exceeds a preset duration threshold, it indicates that the vehicle is only parked for a short time, so the engine is not started; after the timer exceeds this duration threshold, it indicates that the vehicle is not parked for a short time, so the engine is restarted to supply electrical energy to the battery and increase the value of the counter. In this way, on the premise of avoiding the risk of battery power loss, the engine start time after the vehicle first enters the parked state when in a low battery state is delayed, the start frequency of the engine when the vehicle is parked for a short time is reduced, and thus the occurrence frequency of a sudden increase in vehicle noise is reduced.

[0050] If the value of the timer is greater than the initial value, it indicates that the vehicle enters the parked state again when in a low battery state, and the battery may have been hovering around the low battery state for a long time. Even in a short period of time, there is a risk of battery power loss. Therefore, the engine needs to be started after the vehicle enters the parked state again. Therefore, if it is detected that the counter is greater than the initial value, the engine is started to supply electrical energy to the battery to avoid the risk of battery power loss.

[0051] In summary, in the embodiment of the present application, for a hybrid vehicle, when it is detected that the vehicle's battery is in a low battery state and the vehicle is in a parked state, if it is detected that the counter is equal to the initialized initial value, the timer starts timing until the timer exceeds a preset duration threshold, the engine is started to supply electrical energy to the battery, and the value of the counter is increased; if it is detected that the counter is greater than the initial value, the engine is started to supply electrical energy to the battery. In this way, on the premise of avoiding the risk of battery power loss, the engine start time after the vehicle first enters the parked state when in a low battery state is delayed, thereby reducing the start frequency of the engine when the vehicle is parked for a short time, and further reducing the occurrence frequency of a sudden increase in vehicle noise.

[0052] In one embodiment, detecting whether the vehicle is in a parked state includes:

[0053] Detecting whether the vehicle speed exceeds a first vehicle speed threshold;

[0054] If it is detected that the vehicle speed does not exceed the first vehicle speed threshold, it is confirmed that the vehicle is in a parked state.

[0055] In this embodiment, for the detection of the parking state, a first vehicle speed threshold greater than 0 (for example: 3 km / h) is preset. If the vehicle main control unit detects that the vehicle speed does not exceed the first vehicle speed threshold, it confirms that the vehicle is in the parking state; conversely, if it detects that the vehicle speed exceeds the first vehicle speed threshold, it confirms that the vehicle is in a non-parking state.

[0056] In one embodiment, the method provided by this application further includes:

[0057] If it is detected that the engine is started when the vehicle is in the parking state, before detecting again whether the vehicle is in the parking state, it is necessary to monitor in real time whether the vehicle speed exceeds the second vehicle speed threshold;

[0058] When it is detected that the vehicle speed exceeds the second vehicle speed threshold, the counter is reset to the initial value; when the vehicle speed exceeds the second vehicle speed threshold, the vehicle is in the high-power charging state.

[0059] In this embodiment, a second vehicle speed threshold (for example: 20 km / h) is preset. When the vehicle speed exceeds the second vehicle speed threshold, the vehicle will enter the high-power charging state to efficiently charge the battery, so that the battery can quickly get rid of the low-battery state. Therefore, once the vehicle speed exceeds the second vehicle speed threshold, it can be basically confirmed that the battery has once got rid of the low-battery state, and the counter used to confirm whether the vehicle is first parked when the battery is in the low-battery state can be reset.

[0060] Therefore, if the vehicle main control unit detects that the engine has been started when the vehicle is in the parking state, before detecting again whether the vehicle is in the parking state, it is necessary to monitor in real time whether the vehicle speed exceeds the second vehicle speed threshold. Once it is detected that the vehicle speed exceeds the second vehicle speed threshold, it means that the battery has once got rid of the low-battery state, so the counter is reset to the initial value.

[0061] In one embodiment, after detecting whether the vehicle is in the parking state, the method provided by this application further includes:

[0062] When it is detected that the vehicle is in a non-parking state, start the engine to supply electrical energy to the battery.

[0063] It should be noted that if the vehicle is in a non-parking state, it means that there will be a certain degree of background noise during the vehicle driving. Therefore, when the vehicle is not in the parking state, even if the engine is started, the starting noise of the engine will not be too prominent. Therefore, in this embodiment, when the vehicle main control unit detects that the battery is in the low-battery state and the vehicle is in the non-parking state, it directly starts the engine to supply electrical energy to the battery.

[0064] In one embodiment, after starting the engine, the method provided by this application further includes:

[0065] Control the engine to operate in the catalyst heating condition.

[0066] Specifically, in order to meet the requirements of emission regulations, after starting the engine, control the engine to operate in the catalyst heating condition. It should be noted that when operating in the catalyst heating condition, the engine speed is relatively high, the combustion stability is poor, and the overall noise is 2 - 3 dB(A) higher than that in normal idle speed. By reducing the speed or not advancing the ignition angle to improve combustion, the emissions may not meet the standards. Therefore, when operating in the catalyst heating condition, the engine start noise problem is more prominent, and the improvement effect achieved by the method provided in this application is also more obvious.

[0067] In one embodiment, starting the engine to supply electrical energy to the battery includes:

[0068] Send an engine start signal to the engine management system, so that the engine management system responds to the engine start signal to start the engine to supply electrical energy to the battery.

[0069] In this embodiment, after the vehicle main control unit confirms the need to start the engine, it sends an engine start signal to the engine management system EMS (Engine Management System). After receiving the engine start signal, the engine management system starts the engine to supply electrical energy to the battery.

[0070] In one embodiment, increasing the value of the counter includes:

[0071] After receiving the signal fed back by the engine management system for confirming that the engine has started, increase the value of the counter.

[0072] In this embodiment, after starting the engine, the engine management system generates a signal describing that the engine has started, and then feeds back this signal to the vehicle main control unit. When it is detected that the vehicle is in a parked state, the counter is equal to the initial value, and the timer exceeds the duration threshold, after receiving this signal, the vehicle main control unit can confirm that the engine has started, and then increase the value of the counter.

[0073] Figure 2 Shows the detailed flowchart of the hybrid vehicle engine start control in one embodiment of this application.

[0074] See Figure 2 , in one embodiment, the vehicle main control unit VCU monitors the state of charge SOC (State Of Charge) of the vehicle's battery in real time and determines whether the SOC is greater than 3%.

[0075] If it is detected that the SOC is greater than 3%, it indicates that the battery is not in a low power state and there is no immediate need to replenish electrical energy. Therefore, no engine start demand signal is generated to indicate that the engine does not need to be started.

[0076] If it is detected that the SOC is less than or equal to 3%, it indicates that the battery is in a low power state and electrical energy needs to be replenished. Therefore, an engine start demand signal is generated to indicate that the engine needs to be started. Then, the vehicle speed is judged.

[0077] If the vehicle speed is greater than the first vehicle speed threshold of 3 km / h, it indicates that the vehicle is not in a parked state. During vehicle operation, a certain degree of background noise is generated, and even if the engine is started, the starting noise of the engine will not be overly prominent. Therefore, the engine is directly started to supply electrical energy to the battery.

[0078] If the vehicle speed is less than or equal to the first vehicle speed threshold of 3 km / h, it indicates that the vehicle is in a parked state. Then, the counter is judged.

[0079] If the count value Sc of the counter is equal to the initial value 0, it indicates that the vehicle has entered the parked state for the first time while in a low power state. Then, the timer is started to count, and the timing value Tc of the timer is judged. When the timing value Tc is less than the duration threshold of 150 s, it indicates that the vehicle is parked for a short time. Therefore, no engine start signal is generated to indicate that the engine is not started. After the timer Tc is greater than or equal to the duration threshold of 150 s, it indicates that the vehicle is not parked for a short time. Then, an engine start signal is generated and sent to the engine management system EMS to instruct the engine management system to start the engine. After the engine is started, the engine management system feeds back a signal to confirm that the engine has been started to the vehicle main control unit, and then the vehicle main control unit increments the count value Sc of the counter by 1. Then, before judging the vehicle speed again to confirm whether the vehicle is in a parked state, it is judged whether the real-time monitored vehicle speed exceeds the second vehicle speed threshold of 20 km / h.

[0080] If, before judging the vehicle speed again to confirm whether the vehicle is in a parked state, the vehicle speed was once greater than or equal to the second vehicle speed threshold of 20 km / h, it indicates that the battery has once escaped from the low power state. Therefore, the counter is reset to the initial value 0; conversely, if, before judging the vehicle speed again to confirm whether the vehicle is in a parked state, the vehicle speed has always been less than the second vehicle speed threshold of 20 km / h, the counter remains unchanged.

[0081] If the count value Sc of the counter is greater than or equal to 1, it indicates that the vehicle has entered the parked state again while in a low power state. Therefore, an engine start signal is directly generated and sent to the engine management system to instruct the engine management system to start the engine. Then, before judging the vehicle speed again to confirm whether the vehicle is in a parked state, it is judged whether the real-time monitored vehicle speed exceeds the second vehicle speed threshold of 20 km / h.

[0082] Similarly, if the vehicle speed was greater than or equal to the second vehicle speed threshold of 20 km / h before re-determining the vehicle speed to confirm whether the vehicle is in a parked state, the counter is reset to the initial value of 0; conversely, if the vehicle speed was always less than the second vehicle speed threshold of 20 km / h before re-determining the vehicle speed to confirm whether the vehicle is in a parked state, the counter remains unchanged.
