Description

Engine start-stop control method and device and vehicle
Technical Field
The disclosure relates to the field of vehicles, in particular to a start-stop control method and device of an engine and a vehicle.
Background
Along with more and more urban vehicles in China, the traffic jam phenomenon is more and more serious, more and more fuel oil is consumed by the vehicles in traffic jam and idling, so that the fuel oil economy is reduced, the emission of harmful gas is increased, and the urban atmospheric environment is worsened.
In order to solve the problems, the starting and stopping system of the vehicle engine is developed. The working process of the engine starting and stopping system is as follows:
usually, when a driver waits for a red light at an intersection, the driver steps on a brake pedal, after the conditions are met, an engine enters 'automatic start and stop', the engine automatically stops, and a vehicle enters an energy-saving state; after the signal lamp turns green, the driver loosens the brake pedal, and after the conditions are met, the engine enters 'automatic start and stop' and is quickly started.
By the scheme, the energy-saving development trend of the vehicle is met, and the idea that the engine is flamed out when the engine does not work and is started when the engine works is realized.
However, during the actual operation of the vehicle, such situations are often encountered: the driver sees the brake pedal depressed by the red light and the brake pedal released by the green light within a relatively short time interval, for example, no more than 20 seconds, and the vehicle still performs the "automatic start stop" function at this time. And the process from one-time automatic engine flameout to automatic ignition is executed at a short time interval, which is very unnecessary, easily increases the abrasion of the engine and influences the service life of the vehicle-mounted storage battery.

Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
FIG. 1 is a flow chart of an engine start stop control method provided by an exemplary embodiment. Referring to fig. 1, a first aspect of the present disclosure provides an engine start-stop control method, which may include: and step S11, acquiring the image information of the signal lamp under the condition that the automatic engine starting and stopping function is started and the vehicle state meets the engine flameout condition.
For example, the image information of the signal lamp may be obtained by an image obtaining device on the vehicle.
Illustratively, the image acquisition device may be an in-vehicle camera.
Alternatively, the image acquiring device may be a vehicle data recorder, and the vehicle data recorder transmits the acquired image information to the vehicle, so that the vehicle acquires the image information of the signal lamp.
Alternatively, the image information of the signal lamp may be acquired by a photographing terminal on the vehicle, and then the photographing terminal transmits the image information to the vehicle so that the vehicle acquires the image information of the signal lamp. Illustratively, the photographing terminal may be a mobile phone.
The signal lamp is provided with a timer for counting down, and the image information comprises an image of the timer.
And step S12, recognizing the remaining time length of the red light according to the image information.
Illustratively, after the image information is acquired, the features in the image information are extracted, and the remaining time period of the red light contained in the image information is identified by the extracted features.
Illustratively, the feature in the image information may be a pixel arrangement feature, and through identification of the pixel arrangement feature, a number in the image information is obtained, so as to determine the remaining duration of the red light.
For example, the image recognition algorithm model can be trained by using the picture which is marked with the red light remaining time and contains the signal lamp, and after the recognition accuracy meets the requirement, the trained algorithm model is used for recognizing the number in the image information, so that the red light remaining time is determined.
Step S13, determining whether the engine is allowed to shut down according to the remaining time length of the red light and the preset time length;
for example, the preset time period may be a time required for one start-stop of the engine, that is, the preset time period may be determined based on a time period required for the vehicle to complete one engine shut-down until the engine operates normally after re-ignition.
When the remaining duration of the red light is longer than the preset duration, the engine can be determined to be allowed to shut down; when the remaining duration of the red light is less than or equal to the preset duration, the engine can be determined not to be flamed out, unnecessary abrasion of the engine caused by frequent starting and stopping of the engine is avoided, unnecessary discharging of the vehicle-mounted storage battery is reduced, and the service lives of the engine and the vehicle-mounted storage battery are prolonged conveniently.
For example, if the time period required for the vehicle to complete one engine stall until the engine operates normally after reignition is 10 seconds, it is determined that the engine stall is not allowed in the case where the remaining time period of the red light is less than or equal to 10 seconds.
Alternatively, the preset duration can be comprehensively determined according to the engine starting and stopping wear condition, the charging and discharging service life of the vehicle-mounted storage battery and other factors, so that the service lives of the engine and the vehicle-mounted storage battery can be prolonged conveniently.
For example, if the time required by starting and stopping the engine at one time is 10 seconds, the preset time length is comprehensively determined to be 15s by integrating the factors such as the starting and stopping abrasion condition of the engine, the discharging service life of a vehicle-mounted storage battery and the like, namely the engine is controlled to keep normal operation when the remaining red light time length is less than or equal to 15 s.
And step S14, controlling the engine to keep normal operation when determining that the engine is not allowed to be flamed out.
When the engine is determined not to be allowed to be flamed out, the engine is controlled to keep normal operation, so that unnecessary starting and stopping of the engine are reduced, the abrasion of the engine is reduced, the discharging times of the vehicle-mounted storage battery are reduced, and the service lives of the engine and the vehicle-mounted storage battery are prolonged.
FIG. 2 is a flowchart of an engine start stop control method provided by another exemplary embodiment. Exemplarily, referring to fig. 2, step S13 in fig. 1 may include step S131, step S132, and step S133.
After identifying the remaining time period of the red light, step S131 is performed: judging whether the residual red light duration is less than or equal to a preset duration or not, and generating a first judgment result;
when the first determination result is yes, that is, the remaining red light time is less than or equal to the preset time, step S133 is executed: determining that an engine stall is not allowed;
when the first determination result is negative, that is, the remaining red light duration is longer than the preset duration, step S132 is executed: it is determined that the engine is allowed to stall.
For example, in the event that it is determined that engine stall is allowed, engine stall may be controlled by maintaining an automatic start-stop routine of the engine; in the event that it is determined that engine stall is not allowed, the engine may be controlled to remain operating normally by interrupting the automatic start-stop routine.
For example, an automatic start stop routine of the engine may be implemented by an automatic start stop function.
The above exemplary steps S131, S132 and S133 may be expressed as intervention functions of an automatic start-stop function:
Figure BDA0002977372940000071
wherein, t 0 The remaining duration of the red light, t 1 Is a preset duration.
When t is 0 Is less than or equal to t 1 When F (t) 0 ,t 1 ) The return value of the engine start-stop function is 0, the intervention function is used for carrying out intervention on the start-stop function and enabling the start-stop function to be invalid, and the engine is controlled to keep normal operation by interrupting the automatic start-stop routine.
When t is 0 Greater than t 1 When F (t) 0 ,t 1 ) The return value of the engine start-stop function is 1, the intervention function has no intervention on the start-stop function, the automatic start-stop function of the engine continues to control the start and stop of the engine through the start-stop function, namely the engine is controlled to be flamed out through maintaining the automatic start-stop routine of the engine.
Exemplarily, referring to fig. 2, the method in fig. 1 may further include step S15: and under the condition that the countdown corresponding to the remaining time of the red light is finished, controlling the engine to start so as to facilitate the vehicle to start.
For example, if the preset time period is 15s and the remaining time period of the red light is 20s, it is determined that the engine is allowed to be turned off at this time, and the countdown of 20 seconds is started. The automatic start-stop routine of the engine operates to shut down the engine, and when the countdown is finished, the engine is controlled to start so that the vehicle can rapidly advance when the signal lamp is switched, and the delay time caused by starting the engine is reduced.
Alternatively, the countdown time may also be shortened as appropriate, or may be determined as the difference between the remaining time period of the red light and the engine start requirement, so that the engine completes starting when the green light is on, to facilitate direct vehicle start.
FIG. 3 is a flowchart of an engine start stop control method provided by yet another exemplary embodiment. Exemplarily, referring to fig. 3, in the method shown in fig. 2, the step S13 may further include a step S134 and a step S135.
If the first determination result is yes, step S134 is executed: a forward motion state of the vehicle is determined.
For example, the moving state of the front vehicle may include three states of stationary, traveling, and backing.
For example, a radar sensor may be provided on the front side of the vehicle, and the motion state of the preceding vehicle may be determined by a signal detected by the radar sensor and the current speed of the vehicle.
Alternatively, it is also possible to provide an image sensor on the front side of the vehicle, acquire image information of the preceding vehicle by the image sensor, and determine the moving state of the preceding vehicle by determining whether the position of the preceding vehicle in the continuously captured image information changes.
Alternatively, it is also possible to acquire image information of the preceding vehicle through an image sensor on a terminal in the vehicle, and then the terminal transmits the acquired image information to the vehicle so that the vehicle analyzes the motion state of the preceding vehicle. Illustratively, the terminal may be a tachograph.
After the forward movement state of the vehicle is determined, it is determined whether the forward vehicle is in a traveling state, and a second determination result is generated (i.e., step S135).
If the second determination result is negative, that is, if the preceding vehicle is in a stationary state, step S132 is executed to determine that the engine stall is permitted.
When the second determination result is yes, that is, when the preceding vehicle is in a traveling state, although the remaining time of the red light is long, the vehicle needs to travel along with the preceding vehicle when the preceding vehicle travels, and therefore, it is determined that the engine is not allowed to be shut down at this time, so that unnecessary wear due to rapid start of the engine after the engine is stopped is avoided.
Illustratively, on the basis of the method shown in fig. 3, the step S13 may further include:
when the first judgment result is yes, acquiring the position of the vehicle, and determining the distance between the vehicle and the intersection according to the position of the vehicle;
when it is determined that the distance between the vehicle and the intersection is greater than the preset distance, it is determined that the engine is allowed to shut down.
Since the vehicle needs to be movable after the preceding vehicle moves even if the remaining time period of the red light is short. Therefore, when vehicles queue more at the intersection, when the green light is turned on, the vehicles need to wait for a long time to move, and under the condition, if the distance between the vehicles and the intersection is larger than the preset distance, namely the sum of the estimated waiting time from turning on of the green light to moving of the vehicles and the remaining duration of the red light is larger than the preset duration, the engine is determined to be allowed to shut down, so that the fuel economy is improved, and the emission of harmful gas is reduced.
For example, a GPS positioning module may be disposed on the vehicle, and the GPS positioning module is used to obtain the position information of the vehicle and determine the distance between the vehicle and the intersection according to the off-line map data in the vehicle.
Alternatively, the position information of the vehicle can be acquired through a mobile terminal in the vehicle, the mobile terminal sends the acquired position information to the vehicle, and the vehicle determines the distance between the vehicle and the intersection according to the position information and the off-line map data.
When it is determined that the distance of the vehicle from the intersection is less than or equal to the preset distance, it is determined that the engine is not allowed to shut down.
When the distance between the vehicle and the intersection is smaller than or equal to the preset distance, the estimated waiting time from the turning-on of the green light to the movement of the vehicle is smaller than or equal to the preset time, and at the moment, the engine is determined not to be allowed to shut down.
