Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The method for controlling the exhaust emission can be applied to the application environment shown in fig. 1. In one embodiment, the vehicle 101 transmits information of the traffic participants 104 within a preset range 103 to the exhaust emission control device 105 through the on-board sensors 102. The exhaust emission control device 105 may control the exhaust emitted by the vehicle 101 according to the acquired information. The exhaust emission control device 105 may be various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices; or a device in the vehicle, such as a central control device, an auxiliary driving device, a vehicle machine or a navigation device; in addition, the exhaust emission control device 105 may also be a cloud server (Online server), and the cloud server may be implemented by an independent server or a server cluster composed of a plurality of servers, and is connected to the vehicle through a wireless network. The vehicle may be, but is not limited to, an automobile, a motorcycle, and the like, as well as various variations of vehicles. The vehicle referred to herein may be a single oil-circuit vehicle, a single gas-circuit vehicle, a vehicle combining oil and gas, a vehicle combining oil and electricity, or the like. It is to be understood that the embodiment of the present application is not particularly limited to the type of vehicle as long as the vehicle can generate exhaust gas. In addition, different vehicles have different energy source drive types depending on the source of the vehicle drive force. For example, if the source of the vehicle driving force is only fuel such as gasoline, the energy driving type of the vehicle is pure fuel driving; if the source of vehicle drive force includes more than two, the vehicle is of the energy drive type hybrid drive. In addition, if one of the power sources in the hybrid-driven vehicle is a source that does not generate exhaust gas such as electric power, the power source is clean energy. The vehicle hardly generates tail gas in a state of being driven by clean energy.
In one embodiment, referring to fig. 2, a method for controlling exhaust emissions is provided, comprising the steps of:
and step S202, acquiring the driving state of the vehicle. Wherein the vehicle may be a currently driven vehicle. The driving state is used for representing the current state of the vehicle, for example, the driving state comprises a starting state, a driving state and a parking garage state. Wherein, the starting state refers to the process from the shutdown to the starting operation of the engine of the vehicle; the driving state refers to the normal driving process of the vehicle; the parking-in state refers to a process of parking a vehicle in a parking space. In one embodiment, the vehicle may obtain the driving state of the vehicle through a tachograph, a car navigator, or other on-board sensors in the vehicle. In addition, the driving state of the vehicle can be acquired from the cloud server.
And step S204, judging whether a traffic participant exists in the preset range of the vehicle. The preset range is a space range which is set in advance within a certain distance from the vehicle, and can be set according to the diffusion range of tail gas discharged by the vehicle. Further, since the exhaust system of a typical vehicle is located at the rear of the vehicle, the predetermined range may be a space within a predetermined distance from the rear of the vehicle. The traffic participants can be harmed by the tail gas within a preset range.
And S206, if the traffic participants exist in the preset range of the vehicle, selecting a preset exhaust emission mode according to the driving state. The exhaust emission mode comprises the steps of turning off the engine and switching to clean energy driving.
The tail gas emission control method can select a proper tail gas emission mode when a traffic participant approaches the vehicle according to the driving state of the vehicle, and can effectively reduce the harm of the vehicle tail gas to the traffic participant.
Under different driving states, different exhaust emission modes can be adopted, and driving experience of the vehicle is improved. In one embodiment, since the exhaust system of the general vehicle is located at the rear of the vehicle, the determining whether the vehicle is within the preset range includes: judging whether a traffic participant exists in a preset range of the tail of the vehicle; and/or judging whether a traffic participant enters within a preset time within a preset range at the tail of the vehicle.
To further reduce the impact on the traffic participants, the vehicle needs to make judgments about both situations. One situation is that the traffic participant is already close to the vehicle, within a preset range; alternatively, the traffic participant is approaching the vehicle and will enter the predetermined range within a certain time. In both cases, the vehicle may determine that a traffic participant is present within the preset range of the vehicle. The preset time can be set according to actual needs, for example, 3 seconds, 5 seconds, 10 seconds, and the like. Taking 3 seconds as an example, if within 3 seconds, a traffic participant enters a preset range which can be influenced by tail gas emitted by the vehicle, the traffic participant is judged to exist around the vehicle. Alternatively, the preset time can also be determined according to the starting time of the vehicle and the time required for the dissipation of the exhaust gas, for example, the starting time of the vehicle is 3s, the time required for the dissipation of the exhaust gas is 10s, and then the preset time is 13 s.
In one embodiment, the determining whether there is a traffic participant within a preset range of the vehicle includes: and judging whether the traffic participants exist within the preset range of the vehicle or not according to the position of the vehicle, the positions of the traffic participants and the relative speed between the vehicle and the traffic participants.
As a specific embodiment, the coordinates of the vehicle are (a, b), and the velocity vector is v1＝(x1,y1) (ii) a The coordinates of the traffic participant are (c, d), the velocity vector is v2＝(x2,y2). According to the vehicle's velocity vector v1And the velocity vector v of the traffic participant2And obtaining the relative speed v' and the relative angle theta of the vehicle and the traffic participants. The distance d between the vehicle and the traffic participant is obtained from the coordinates of the vehicle and the coordinates of the traffic participant. Further, whether the vehicle exists in the preset range within the preset time or not is judged according to the distance d, the relative speed v' and the relative angle thetaAt the traffic participants.
In particular, traffic participants include pedestrians, non-motorized vehicles, and other vehicles that are endangered by exhaust gases. In one embodiment, if there is no traffic participant within the predetermined range of the vehicle, the step S204 is repeatedly executed. And if the traffic participants exist within the preset range of the vehicle, selecting a preset exhaust emission mode according to the driving state.
In one embodiment, step S206, selecting a preset exhaust emission mode according to the driving state includes:
step S2061, the energy drive type of the vehicle is acquired. The energy driving type refers to a power source of a vehicle, such as hybrid driving, pure fuel driving and the like. Pure fuel driven such as gasoline driven, diesel driven, ethanol driven, natural gas driven, etc.; hybrid drive is a drive mode containing more than two power sources, including oil-gas hybrid, oil-electricity hybrid and the like.
And S2062, selecting a preset exhaust emission mode according to the energy driving type of the vehicle and the driving state. Specifically, the energy driving type and the driving state can be used as conditions for selecting the exhaust emission mode, and when different conditions are met, the corresponding exhaust emission modes are different. For example, when the vehicle is driven by hybrid power, the starting state, the running state or the parking and warehousing state can correspond to different exhaust emission modes to control exhaust emission; similarly, when the vehicle is driven by fuel, the starting state, the driving state or the parking and warehousing state can correspond to different exhaust emission modes to control exhaust emission.
In one embodiment, the energy drive type of the vehicle is hybrid drive, and the step of selecting the preset exhaust emission mode according to the energy drive type of the vehicle and the driving state comprises: adjusting the energy drive of the vehicle to a clean energy drive.
In addition, when the energy drive type is the hybrid drive, if there is a traffic participant within a preset range of the vehicle, the energy drive can be adjusted to the clean energy drive regardless of whether the driving state of the vehicle is the start state, the driving state, or the parking garage state.
As a specific embodiment, when the driving state is the starting state and the energy driving type of the vehicle is the fuel driving, if there are traffic participants within a preset range of the vehicle, the engine of the vehicle is controlled to be turned off. The engine may then be manually restarted. Alternatively, the vehicle will automatically start the fuel engine upon detecting that a participant in the traffic within the predetermined range of the vehicle has left the predetermined range.
In another embodiment, referring to fig. 3, when the driving state is a driving state, the determining whether there is a traffic participant within a preset range of the vehicle further includes:
step S302, acquiring the traveling information of the traffic participants. The traveling information comprises the traveling speed and the traveling direction of the traffic participants. In another embodiment, the travel information further includes the relative speed of the transportation participant and the vehicle, and the relative angle of travel of the vehicle.
Step S304, calculating the duration of the traffic participant in the preset range according to the traveling information of the traffic participant and the driving state. In particular, during the following of the vehicle by the traffic participant, there are a difference in the driving speed and a difference in the driving angle between the traffic participant and the vehicle. Wherein, the difference of the running speeds is a relative speed, and the difference of the running angles is a relative angle. Due to the existence of the relative speed and the relative angle, the position relationship between the traffic participant and the vehicle gradually changes, and therefore, the traffic participant gradually departs from the preset range. Therefore, the time length of the traffic participant in the preset range can be obtained by acquiring the time of the traffic participant entering the preset range and the time of the traffic participant leaving the preset range.
Step S306, if the duration of the traffic participant in the preset range exceeds a preset threshold, selecting a preset tail gas emission mode. For example, if the preset threshold is 3s and the time duration of the traffic participant within the preset range is 4s, the energy drive of the vehicle is adjusted to be the clean energy drive.
In one embodiment, step S304 includes:
step S3041, acquiring a driving speed and a driving direction of a vehicle;
step S3042, obtaining the traveling speed and the traveling direction of the traffic participant;
step S3043, calculating a duration of the transportation participant within the preset range according to the driving speed and the driving direction of the transportation vehicle and the traveling speed and the traveling direction of the transportation participant.
As a specific example, the preset range is a rectangle with a length of 5m and a width of 3 m; the relative speed of the traffic participant and the vehicle is-2 m/s, namely the traveling speed of the traffic participant is less than the traveling speed of the vehicle; the relative angle between the traffic participant and the vehicle is 0 degrees, and the traffic participant and the vehicle travel along the same traffic lane; if the traffic participant is located at the position 1m at the tail of the vehicle in the initial state, the time that the traffic participant is located within the preset range is calculated to be 2s from the moment until the traffic participant leaves the preset range.
As an alternative embodiment, when the driving state is the driving state and the energy driving type of the vehicle is the fuel driving, if the transportation participant exists within the preset range of the vehicle, the vehicle is controlled to give a prompt to the transportation participant within the preset range, for example, "you are in a position where the pollution of the exhaust gas is heavy, please keep a distance with the vehicle".
In one embodiment, if the driving state is a parking garage state; the judging whether a traffic participant exists in the preset range of the vehicle comprises the following steps:
detecting whether a non-motorized lane or the traffic participant exists within a preset area from a planned stop point of the vehicle. The preset area refers to the distance around the planned parking point. As an alternative embodiment, the preset area may be set with reference to the size of the preset range, for example, the preset area may be the same as the size of the preset range. In one embodiment, the predetermined area is an area within a fixed distance from each side of the planned parking point, for example, a rectangular area within 4m from each side of the planned parking point. It is understood that a non-motorized lane includes a sidewalk.
In one embodiment, referring to fig. 4, if the non-motor vehicle lane or the transportation participant is within the predetermined range of the vehicle, the step of selecting a predetermined exhaust emission mode according to the driving state and the traveling information of the transportation participant comprises:
step S402, acquiring the relative position of the non-motor lane or the traffic participant and the planned stop point. Wherein the relative position refers to the direction and position of the non-motor lane or the traffic participant relative to the parking space. In particular, non-motorized lanes include motorways, bicycle lanes, sidewalks, and the like. Wherein, in the current state, no non-motor vehicles or pedestrians may exist in the non-motor vehicle lane; however, during the parking and warehousing process, non-motor vehicles or pedestrians may pass through the vehicle at a certain moment.
And S404, controlling the vehicle to drive into a parking space, and enabling the tail of the vehicle to be far away from the non-motor vehicle lane or the traffic participants. Specifically, the control of the vehicle to enter the parking space may be that the vehicle enters the parking space through an automatic driving system, or that the driver manually operates the vehicle to enter the parking spot.
In one embodiment, referring to fig. 5, the planned parking spot is a rectangle X with a length of a meter and a width of b meters, wherein two long sides are respectively denoted by a1 and a2, and two widths are respectively denoted by b1 and b 2. The position of the non-motor vehicle lane is located within a rectangular area Y of 2m at a distance b 1. In this case, in order to avoid the influence on the traffic participants passing through the non-motor lane after the vehicle enters the parking space, the head of the vehicle can be controlled to enter the position b1, and the tail of the vehicle is stopped at the position b2, so that the tail of the vehicle can be far away from the non-motor lane, and the influence of the tail gas discharged from the tail of the vehicle on the traffic participants in the non-motor lane can be reduced or avoided.
In another embodiment, when the driving state is a parking garage state and the energy drive type of the vehicle is hybrid drive, if there are traffic participants within a preset range of the vehicle and/or in a preset area of a parking spot, the energy drive of the vehicle is adjusted to be clean energy drive.
In one embodiment, after step S402, the method further includes: outputting a warning signal for warning a driver of the non-motorized lane or the traffic participant. When the non-motor vehicle lane or the traffic participants exist in the preset range of the vehicle and the vehicle is driven into the parking space, the warning system can be started to send a warning signal to the driver. Specifically, the driver may be visually prompted by the in-vehicle display system, for example, to highlight the b1 location; or output a voice prompt.
The embodiment takes the non-motor lane as the condition for judging the parking mode of the vehicle, and can effectively prevent the tail gas harm to traffic participants entering the non-motor lane in the parking process. In the parking process of the vehicle, the tail part of the vehicle is already parked by avoiding the non-motor vehicle lane, so that when the vehicle is started again, the probability of traffic participants in the preset range of the tail part of the vehicle is greatly reduced.
In one embodiment, the exhaust emission mode is adjusted to the fuel driving mode when the traffic participant departs from a preset range of the vehicle or receives a mode switching command input by a user. For example, when the following state of the traffic participant is released in the driving state, the user manually adjusts the exhaust emission mode to the fuel driving mode.
According to the tail gas emission control method, the appropriate tail gas emission mode can be selected according to the driving state of the vehicle and whether a traffic participant is close to the vehicle within the preset range of the vehicle, and the harm of the vehicle tail gas to the traffic participant can be effectively reduced.
In addition, under different driving states, the method and the device can also adopt corresponding different exhaust emission modes, and the driving experience of the vehicle is well considered.
