The present application will be further described in detail below with reference to specific embodiments and with reference to the accompanying drawings, in order to make the objects, technical solutions and advantages of the present application more apparent.

Fig. 1 is a schematic flow chart of a control method for stopping an engine of a vehicle, which is provided by the embodiment of the application, and is suitable for stopping the engine under different stopping working conditions, so as to improve the rationality of stopping the engine, improve the safety of the vehicle, improve the reasonable utilization of energy sources of the vehicle, meet the stopping requirements of users to the maximum extent, ensure that the vehicle does not have obvious power loss feeling, and facilitate the improvement of driving experience. The vehicle engine stop control method may be performed by a vehicle engine stop control device that may be implemented in software and/or hardware and integrated into an electronic apparatus.

As shown in fig. 1, the vehicle engine stop control method includes the steps of:

s110, responding to received shutdown source signals of the engine, and determining the priority of the shutdown source signals.

Wherein, different engine stop conditions correspond to the only stop source signal, or said, different stop source signals correspond to different engine stop conditions. In order to give consideration to various engine stop conditions, in the embodiment of the application, a priority is set for each engine stop condition, or a priority is set for a stop source signal corresponding to each engine stop condition, and then the vehicle is controlled by adopting different control strategies according to the priority, so that the purpose of stopping the vehicle engine is achieved.

By setting the priority for the shutdown source signals, consideration of various engine shutdown conditions is achieved, and further shutdown rationality of an engine is improved, meanwhile, the shutdown requirements of a user can be met to the greatest extent, and driving experience is improved.

S120, responding to the priority of the stop source signal as a middle level, and controlling an engine of the vehicle according to the current gear state of the rear axle of the vehicle; wherein, when the power mode of the vehicle is switched to the pure electric mode, the mid-level stop source signal is triggered.

When the priority of the shutdown source signal is the intermediate level, the corresponding control strategy is: and controlling the engine of the vehicle according to the current gear state of the rear axle of the vehicle. For example, when the current gear state of the rear axle of the vehicle is "in gear", the engine of the vehicle can be directly controlled to stop, because the motor of the rear axle of the vehicle can provide power for the vehicle when the gear state of the rear axle of the vehicle is "in gear", and even if the engine stops, the engine does not exert much influence on the overall vehicle power. In other words, the power lost by the whole vehicle caused by the stop of the engine can be compensated by the power provided by the rear axle motor, so that a driver does not feel strong power loss feeling, and the driving experience is improved while the power of the vehicle is ensured. Correspondingly, when the current gear state of the rear axle of the vehicle is neutral, namely, the vehicle is not in gear, the rear axle gear-shifting request can be triggered firstly, and when the rear axle is in gear successfully, the engine is controlled to stop, so that the power of the whole vehicle is not influenced, the purpose of stopping the engine can be achieved, and the stop requirement of a user is met.

For example, when the power mode of the vehicle is switched to the electric-only mode (including switching from the intelligent hybrid mode to the electric-only mode, and switching from the electric-only priority mode to the electric-only mode), a mid-level shutdown source signal is triggered. When the power mode of the vehicle is switched to the pure mode, the engine of the vehicle is controlled according to the current gear state of the rear axle of the vehicle, so that the stopping requirement can be met, the power of the whole vehicle is not influenced, and the stopping rationality of the engine is improved.

The driver can manually trigger the power mode switching instruction of the vehicle, for example, the driver wants to save fuel consumption, electricity burning is considered to be more economical and cost-effective, and at the moment, the driver can actively trigger the power mode switching instruction of the vehicle to enable the vehicle to enter a pure electric mode, and when the vehicle enters the pure electric mode, the engine is controlled to stop so as to save fuel consumption. In order to ensure that the power of the whole vehicle is not affected, when the power mode of the vehicle is switched to a pure electric mode, a medium-level stop source signal is triggered, and at the moment, the engine of the vehicle is controlled according to the current gear state of the rear axle of the vehicle.

According to the vehicle engine shutdown control method provided by the embodiment of the application, when the shutdown source signal of the engine is received, the priority of the shutdown source signal is determined, and then the engine is shutdown controlled according to the shutdown priority, so that various engine shutdown working conditions are considered, the shutdown rationality of the engine is improved, the engine shutdown requirement of a user can be met to the maximum extent, and the driving experience is improved. Through setting the power mode of the vehicle to be the shutdown level of the medium priority (namely, the priority of the shutdown source signal corresponding to the power mode is the medium level) under the condition that the power mode of the vehicle is switched to the pure power mode, when the medium-level shutdown source signal is detected, the engine of the vehicle is controlled according to the current gear state of the rear axle of the vehicle, so that the power is not lost when the vehicle runs, the shutdown requirement of a user can be met, the shutdown rationality of the engine is improved, and the driving experience is improved.

On the basis of the above embodiment, fig. 2 provides a schematic flow chart of another vehicle engine shutdown control method, and in this embodiment, the step S120 "responding to the priority of the shutdown source signal is a middle level", and the control of the vehicle engine according to the current gear state of the rear axle of the vehicle "is specifically refined: and responding to the priority of the stop source signal as the middle level and the current gear state of the rear axle of the vehicle as the gear state, controlling the engine of the vehicle to stop, responding to the priority of the stop source signal as the middle level and the current gear state of the rear axle of the vehicle as the neutral gear state, triggering a rear axle gear request, and controlling the engine of the vehicle to stop based on the response result of the rear axle gear request.

As shown in fig. 2, the vehicle engine stop control method includes the steps of:

and S210, responding to receiving a stop source signal of the engine, and determining the priority of the stop source signal, wherein when the power mode of the vehicle is switched to the pure electric mode, the intermediate-stage stop source signal is triggered.

And S220, controlling the engine of the vehicle to stop in response to the priority of the stop source signal being a medium level and the current gear state of the rear axle of the vehicle being a gear-in state.

Specifically, taking a new energy automobile with a DHT-2 architecture as an example, a front axle of the automobile is provided with a motor and an engine for providing driving force for front wheels. The rear axle is provided with an electric motor for providing driving force to the rear wheels. When the speed of a motor vehicle is lower, the rear axle motor provides most power, and gradually deviates to the front drive along with the lifting of the speed of the motor vehicle, so that the phenomenon of gear disengagement possibly occurs in the rear axle, namely, the power of the whole motor vehicle is provided by the front axle, at the moment, if the engine is stopped, only the front axle motor can provide power for the whole motor vehicle, and the load capacity of the motor of the front axle is smaller in general, so that the motor vehicle has stronger power loss sense. Therefore, when the rear axle is out of gear, the engine is not suitable for stopping, otherwise, strong power loss feeling can be brought to a driver, and the driving experience is influenced due to insufficient power of the whole vehicle.

Thus, in an embodiment of the present application, when a power mode of the vehicle is detected to be switched to a pure mode (engine stop is required in the pure mode), a mid-level stop source signal is triggered, when the mid-level stop source signal is detected, the current gear state of the rear axle of the vehicle is determined, if the gear state is the gear state, the engine stop of the vehicle is controlled, otherwise, a rear axle gear request is triggered, and the engine stop of the vehicle is controlled based on the response result of the rear axle gear request instead of directly controlling the engine stop.

And S230, responding to the condition that the priority of the stop source signal is a medium level and the current gear state of the rear axle of the vehicle is a neutral gear state, triggering a rear axle gear engaging request, and performing stop control on an engine of the vehicle based on a response result aiming at the rear axle gear engaging request.

Illustratively, the response result includes a successful rear axle gear or a rear axle gear failure, and the engine of the vehicle is controlled to stop based on the response result for the rear axle gear request, including:

Wherein, can judge whether the rear axle is put into gear and is out of order through following mode:

starting timing when the rear axle gear shifting request is triggered, if the rear axle gear shifting success signal is not received for more than 2s (the value can be calibrated), the rear axle gear shifting fault can be determined. Or upon receipt of an explicit rear axle upshift fault signal, a rear axle upshift fault may be determined.

When a mid-level stop source signal is detected, the embodiment controls the engine of the vehicle according to the current gear state of the rear axle of the vehicle, and if the current gear state of the rear axle of the vehicle is 'gear engaged', the engine is directly controlled to stop, namely an engine stop instruction is triggered, and the instruction is executed by a related executing mechanism. If the current gear state of the rear axle of the vehicle is neutral, the engine is not directly controlled to stop, but the rear axle gear engaging request is triggered, and further control operation is carried out according to the rear axle gear engaging result, so that the power is not lost when the vehicle runs, the stop requirement of a user can be met, the stop rationality of the engine is improved, and the driving experience is improved.

On the basis of the above embodiment, fig. 3 provides a schematic flow chart of another vehicle engine shutdown control method, and in this embodiment, a control strategy for a high-priority shutdown source signal and a low-priority shutdown source signal is added, which specifically includes: controlling an engine of the vehicle to stop in response to the priority of the stop source signal being advanced; and controlling an engine of the vehicle according to the shutdown source signal in response to the priority of the shutdown source signal being low.

S330, controlling the engine of the vehicle to stop in response to the priority of the stop source signal being high.

And S340, controlling the engine of the vehicle according to the stopping source signal in response to the priority of the stopping source signal being low.

Wherein determining the priority of the shutdown source signal comprises:

And determining the level corresponding to the data bit occupied by the shutdown source signal as the priority of the shutdown source signal according to the corresponding relation between each data bit and the level. I.e. different data bits represent different priority sources of stalling.

In some embodiments, the vehicle engine stop control method further comprises:

The engine stopping device has the advantages that the stopping working conditions of various engines are considered, the stopping rationality of the engines is improved, meanwhile, the engine stopping requirements of users can be met to the greatest extent, and the driving experience is improved. Specifically, if the priority of the stop source signal is a medium level, the current gear state of the rear axle of the vehicle is determined.
