Example 1

According to an embodiment of the present invention, there is provided an embodiment of a method of controlling an engine of a vehicle, it being noted that the steps shown in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and that although a logical sequence is shown in the flowchart, in some cases the steps shown or described may be performed in a different order than here.

Fig. 1 is a flowchart of a control method of an engine of a vehicle according to an embodiment of the present invention, as shown in fig. 1, the method may include the steps of:

step S101, detecting an indication state of a traffic signal lamp.

In the technical solution provided in the above step S101 of the present invention, an indication state of a traffic signal is detected, where the traffic signal is located on a road section on which a vehicle to be controlled travels, and the indication state may be at least a first target indication state or a second target indication state, where the first target indication state is used for indicating that the vehicle is prohibited from traveling on the road section on which the vehicle travels, for example, the first target indication state may be a red light state, and the second target indication state is used for indicating that the vehicle is allowed to travel on the road section on which the vehicle travels, for example, the second target state may be a green light state.

In this embodiment, the indication state of the traffic light on the road section on which the vehicle to be controlled is traveling is detected, for example, the color information or the image information of the traffic light may be acquired by the in-vehicle navigation system, so that the indication state of the traffic light is detected from the acquired information of the traffic light, which is merely an exemplary example and a specific method of detecting the indication state of the traffic light is not limited.

For example, the car navigation system may collect image data of the traffic signal lamp through a sensor or a camera, and detect an indication state of the traffic signal lamp by performing image analysis on the collected image data of the traffic signal lamp. If the color of the traffic signal lamp is a first color, determining that the indication state of the traffic signal lamp is a first target indication state, wherein the first color can be red; if the color of the traffic signal light is a second color, determining that the indication state of the traffic signal light is a second target indication state, wherein the second color may be green.

Step S102, controlling the engine of the vehicle to stop working in response to the indication state being the first target indication state and the vehicle being in a stop driving state.

In the technical solution provided in the above step S102 of the present invention, after detecting the indication state of the traffic light according to step S101, if the indication state of the traffic light is the first target indication state, and the vehicle is in the stopped driving state, the engine of the vehicle is controlled to stop working, wherein the first target indication state is used for indicating that the vehicle is prohibited from passing through the road section.

In this embodiment, when the indication state of the traffic signal lamp is the first target indication state, since the first target indication state is used to indicate that the vehicle is prohibited from passing on the road section, in this case, it is determined whether the vehicle is in the stopped running state, and if the vehicle is in the stopped state, the engine of the vehicle can be controlled to stop operating to reduce the fuel discharge.

For example, whether the vehicle is in a stopped running state may be determined by acquiring the vehicle speed of the vehicle, the state of a transmission of the vehicle, and the like. For example, when the vehicle speed is 0, and when the transmission of the vehicle is in a P range (stop range) state, it is determined that the vehicle is in a stopped running state, which is merely an exemplary example, and the specific contents of the condition for determining that the vehicle is in the stopped running state are not limited.

Alternatively, when it is determined that the vehicle is in the stopped running state, a stop operation instruction for instructing the engine of the vehicle to stop operation may be transmitted to the engine of the vehicle.

In this embodiment, when the indication state of the traffic signal lamp is the first target indication state and the vehicle is in the stopped running state, the engine of the vehicle is controlled to stop working, so as to reduce fuel emission and improve fuel economy of the vehicle. After controlling the engine of the vehicle to stop operation, step S103 may be performed.

Step S103, during the process of stopping the engine of the vehicle, obtaining the target duration of the traffic signal from the first target indication state to the second target indication state.

In the technical solution provided in the above step S103 of the present invention, after the engine of the vehicle is controlled to stop working according to step S102, a target duration of the traffic signal from the first target indication state to the second target indication state may be obtained, where the second target indication state is used to indicate that the vehicle is allowed to pass on the road section. For example, the second target indication state may be a green light state, which is merely an exemplary example, and the specific content of the second target indication state is not limited.

In this embodiment, as is apparent from the foregoing description, the first target indication state is used to indicate that the vehicle is prohibited from passing through the road section on which the vehicle is traveling, and the second target indication state is used to indicate that the vehicle is permitted to pass through the road section on which the vehicle is traveling, and therefore, after the engine of the vehicle is controlled to stop operating, a target period of time for which the traffic signal is to be switched from the first target indication state to the second target indication state, which is used to indicate a period of time for which the traffic signal is to be switched from the state in which the vehicle is prohibited from communicating to the state in which the vehicle is permitted to pass, can be acquired.

For example, the electronic map in the vehicle navigation system of the vehicle is provided with a traffic signal light countdown function, based on which a target duration for which the traffic signal light is to be converted from a state in which vehicle communication is prohibited to a state in which vehicle communication is permitted can be obtained by starting the traffic signal light countdown function in the electronic map of the vehicle, which is only an exemplary example and a specific method for obtaining the target duration is not limited.

In this embodiment, during the stopping of the engine of the vehicle, the target duration of the traffic signal from the first target indication state to the second target indication state is obtained, so that the time that the vehicle stays on the current road section can be predetermined, and a data reference is provided for the subsequent early starting of the engine. After the target time period is acquired, step S104 may be performed according to the acquired target time period.

And step S104, in response to the target duration being smaller than the target duration threshold value and the engine of the vehicle meeting the starting condition, controlling the engine to continue to work.

In the technical solution provided in the above step S104 of the present invention, after the target time length is obtained according to step S103, if the response time length is smaller than the target time length threshold and the engine of the vehicle meets the starting condition, the engine is controlled to continue to work. The target duration threshold is a duration threshold of a preset traffic signal lamp from a first target indication state to a second target indication state. For example, the target duration threshold may be 5 seconds(s), which is merely an illustrative example, and specific values of the target duration threshold are not limited.

In this embodiment, after determining the target duration for the traffic signal to be switched from the first target indication state to the second target indication state, the target duration may be compared with the target duration threshold, and if the target duration is less than the target duration threshold, it is indicated that the state of the traffic signal will be switched to the state allowing the vehicle to pass in a shorter time, and in this case, it may be further determined whether the engine of the vehicle satisfies the start condition.

Optionally, the starting condition of the engine of the vehicle at least includes that the door state of the vehicle is in a closed state, the belt state of the vehicle is in a tightened state, and the hood state of the vehicle is in a closed state, based on which the door state, the belt state, and the hood state of the vehicle can be obtained, and the door state, the belt state, and the hood state of the vehicle are compared with the door state, the belt state, and the hood state in the engine starting condition, so as to determine whether the engine of the vehicle satisfies the starting condition. If the door state of the vehicle is a closed state, the seatbelt state of the vehicle is a tightened state, and the hood state of the vehicle is a closed state, it can be determined that the engine of the vehicle satisfies the start condition.

In this embodiment, when the target time length is smaller than the target time length threshold value, the door state, the seat belt state, and the hood state of the vehicle may be acquired, and when the door state of the vehicle is the closed state, the seat belt state of the vehicle is the tightened state, and the hood state of the vehicle is the closed state, the engine of the vehicle is controlled to start, that is, the engine of the vehicle is controlled to be switched from the stopped operation state to the operation state.

The above-described embodiment may be executed by a control device of a vehicle engine, for example, a transmitter controller of a vehicle.

According to the method, the step S101 to the step S104 are performed, when the indication state of the traffic signal lamp indicates that the vehicle is prohibited from passing, the engine of the vehicle is controlled to stop working, the target duration corresponding to the state of the traffic signal lamp that the vehicle is prohibited from passing is obtained, when the target duration is smaller than the target duration threshold, whether the engine of the vehicle meets the starting condition is judged, if the engine of the vehicle meets the starting condition, the engine is controlled to continue working, so that the engine can be started in advance when the state of the traffic signal lamp that the vehicle is prohibited from passing is to be switched to the state of the vehicle is permitted to pass, the vehicle can exit a stop line at the first time when the traffic signal lamp is switched to the state of the vehicle is permitted to pass, the purposes of greatly improving the driving experience and controlling the pleasure of the vehicle are achieved, the technical effect of improving the acceleration time of the vehicle in the idle starting and stopping process of the vehicle is achieved, and the technical problem that the vehicle is not accelerated in the idle starting and stopping process of the vehicle is solved.

The above-described method of this embodiment is further described below.

As an optional embodiment, step S104, acquiring a door state of the vehicle, a seat belt state of the vehicle, and a bonnet state of the vehicle; in response to the door state being a closed state, the seat belt state being a tightened state, and the hood state being a closed state, it is determined that the engine satisfies a start condition.

In this embodiment, the starting conditions of the engine may include at least: based on the state of the door of the vehicle, the state of the safety belt of the vehicle and the state of the engine cover of the vehicle being in the closed state, the state of the door of the vehicle, the state of the safety belt of the vehicle and the state of the engine cover of the vehicle can be obtained, so that whether the state of the door, the state of the safety belt and the state of the engine cover meet the starting condition of the engine is judged.

Alternatively, the door state of the vehicle is obtained by a body control module of the vehicle, the seat belt state of the vehicle is obtained by a seat belt sensor, and the hood state of the vehicle is obtained by a central control system of the vehicle, which are only illustrative examples, and specific methods of obtaining the door state, the seat belt state, and the hood state of the vehicle are not limited.

Alternatively, when the door state is the closed state, the seat belt state is the tightened state, and the hood state is the closed state, it is determined that the engine satisfies the start condition.

As an alternative embodiment, step S104 controls the engine of the vehicle to continue to stop operating in response to the target duration being not less than the target duration threshold.

In this embodiment, when the target time period is not less than the target time period threshold value, it is explained that the time period for which the traffic signal is to be converted from the no-vehicle-traffic state to the no-vehicle-traffic state is longer, in which case the engine of the vehicle may be controlled to continue to stop operating, that is, the transmitter of the vehicle may be controlled to continue to maintain the stopped operating state.

For example, assuming that the target duration threshold is 5s and the target duration is 6s, that is, the duration in which the traffic signal is to be converted from the no-vehicle-traffic state to the no-vehicle-traffic state is 6s, since 6s >5s, that is, the target duration is not less than the target duration threshold, in this case, the engine of the vehicle may be controlled to continue to stop operating.

As an optional embodiment, step S103, during a process of stopping an engine of the vehicle, obtains a target duration of a traffic signal from a first target indication state to be converted to a second target indication state, including: in response to the engine stopping, starting a traffic signal light countdown function of an electronic map of the vehicle, wherein the traffic signal light countdown function is used for determining the duration of time for the traffic signal light to be converted from a first target indication state to a second target indication state; determining the display duration of an electronic map of the vehicle based on the traffic signal lamp countdown function; and determining the display duration as the target duration.

In this embodiment, when the engine stops operating, the traffic signal light countdown function of the electronic map of the vehicle may be started, which is used to determine the time period during which the traffic signal light is to be converted from the first target indication state to the second target indication state, that is, the time period during which the traffic signal light is to be converted from the no-vehicle-traffic state to the no-vehicle-traffic state, where the time period during which the traffic signal light is to be converted from the first target indication state to the second target indication state, which is determined by the traffic signal light countdown function, may be displayed on the electronic map of the vehicle, based on which the display time period on the electronic map of the vehicle may be determined as the target time period.

For example, when the engine stops working, a traffic signal lamp countdown function of an electronic map of the vehicle is started, and when the remaining duration of the red light is displayed in the electronic map of the vehicle to be 5s, the target duration is determined to be 5s.

As an optional embodiment, step S104 generates a prompt message in response to the target duration being less than the target duration threshold, where the prompt message includes at least the target duration.

In this embodiment, when the target duration is less than the target duration threshold, a prompt message may be generated, where the prompt message is used to remind the driver of the state of the traffic signal, and the prompt message at least includes the target duration for which the traffic signal is to be converted from the no-traffic state to the no-traffic state.

For example, assuming that the target duration is 3s and the target duration is less than the target duration threshold, a prompt message may be generated, where the prompt message may be "the current red light remaining duration is 3s, please start the vehicle", which is only an exemplary example and not limited to the specific content of the prompt message.

As an alternative embodiment, after generating the prompt message, the method for controlling the engine of the vehicle further includes: and controlling a loudspeaker of the vehicle to play the prompt information of the vehicle, and/or sending the prompt information to a vehicle-mounted navigation system of the vehicle through a wireless communication link, wherein the vehicle-mounted navigation system is used for displaying the prompt information.

In this embodiment, after the generated prompt information, the speaker of the vehicle is controlled to play the generated prompt information, or the prompt information is transmitted to the car navigation system of the vehicle through the wireless communication link, and the car navigation system displays the generated prompt information on the display interface.

Optionally, through the mode that voice broadcast prompt message and car navigation system show prompt message, the condition of suggestion driver current traffic light that can be more swift for the driver in time starts the vehicle, promotes the acceleration time of vehicle, and then avoids just starting the vehicle after traffic light changes, leads to the slower problem of vehicle acceleration.

The above-described embodiment may be performed by a control device of a vehicle engine.

In this embodiment, by detecting the indication state of the traffic signal lamp, when the indication state of the traffic signal lamp indicates that the vehicle is prohibited from passing, the engine of the vehicle is controlled to stop working, and the target duration corresponding to the state of the traffic signal lamp that the vehicle is prohibited from passing is obtained, when the target duration is smaller than the target duration threshold, whether the engine of the vehicle meets the starting condition is judged, if the engine of the vehicle meets the starting condition, the engine is controlled to continue working, so that the engine can be started in advance when the state of the traffic signal lamp that the vehicle is prohibited from passing is to be switched to the state of the vehicle is permitted to pass, the vehicle can be driven out of the stop line at the first time when the traffic signal lamp is switched to the state of the vehicle is permitted to pass, the aim of greatly improving the driving experience and the control pleasure of the vehicle is achieved, and the technical effect of improving the acceleration time of the vehicle is achieved in the idle starting and stopping process of the vehicle, and the technical problem of untimely acceleration of the vehicle is solved in the idle starting and stopping process of the vehicle is solved.
