[0048] FIG1 shows a flow chart of a vehicle control method based on alcohol detection in one embodiment. As shown in FIG1 , a vehicle control method based on alcohol detection is provided. The method may include the following steps 101 to 102 .

[0049] In step 101, when the driver blows into the air pipe, a first alcohol concentration detected by a first alcohol sensor via a first air pump connected to the air pipe and a second alcohol concentration detected by a second alcohol sensor via a second air pump connected to the air pipe are obtained;

[0050] In step 102 , the vehicle is started and concentration display control is performed according to a first alcohol concentration and a second alcohol concentration, wherein the first alcohol concentration is different from the second alcohol concentration.

[0051] It can be understood that the first alcohol sensor and the second alcohol sensor can be semiconductor sensors, electrochemical sensors, infrared sensors, etc. Semiconductor sensors have low detection accuracy and slow response time but are relatively low in price. Electrochemical sensors have high detection accuracy but are easily affected by high and low temperatures. Infrared sensors have high detection accuracy but are expensive.

[0052] In some embodiments, the first alcohol sensor and the second alcohol sensor both use lower-priced semiconductor alcohol sensors, and the vehicle control method of the present application compensates for the defects of low detection accuracy and slow response time of semiconductor alcohol sensors, thereby achieving the purpose of quickly and accurately controlling the vehicle.

[0053] Figure 2 shows a schematic diagram of the structure of a vehicle control system based on alcohol detection in one embodiment. As shown in Figure 2, the vehicle control system based on alcohol detection may include a vehicle control device based on alcohol detection, an air blow pipe, a first air pump, a first alcohol sensor, a second air pump, and a second alcohol sensor. The first air pump and the second air pump are respectively connected to the air blow pipe. The first air pump is connected to the vehicle control device based on alcohol detection via the first alcohol sensor, and the second air pump is connected to the vehicle control device based on alcohol detection via the second alcohol sensor.

[0054] During implementation, the alcohol-detection-based vehicle control device can be located externally or internally in the vehicle, and this is not a limitation in the present embodiment. After boarding the vehicle, the driver blows into the air blowpipe. The air is pumped by a first air pump and a second air pump to the first and second alcohol sensors, respectively, for reaction. The alcohol-detection-based vehicle control device processes the alcohol concentrations detected by the two alcohol sensors, determines whether the vehicle is authorized to start, and displays the alcohol concentration. Of course, the relevant detection data can also be uploaded to a cloud platform for system management.

[0055] In some embodiments, the first air pump is an intermittent air pump, the second air pump is a continuous air pump, and starting and controlling the concentration display of the vehicle according to the first alcohol concentration and the second alcohol concentration may include: determining a third alcohol concentration based on the first alcohol concentration detected by the first alcohol sensor and a preset mapping relationship; wherein the preset mapping relationship is used to characterize the relationship between the single response concentration of the first alcohol sensor and the actual alcohol concentration; starting and controlling the vehicle according to the third alcohol concentration; correcting the second alcohol concentration according to the third alcohol concentration to obtain a target alcohol concentration; and controlling the vehicle to display the target alcohol concentration.

[0056] Figure 3 shows the response and recovery curves of the first alcohol sensor when the first air pump in Figure 2 is intermittent, with time plotted on the abscissa and alcohol concentration (in ppm) on the ordinate. As shown in Figure 3, the first alcohol sensor reacts incompletely with alcohol during intermittent pumping, resulting in multiple peaks in the detected alcohol concentration. Figure 4 shows the response and recovery curves of the second alcohol sensor when the second air pump in Figure 2 is continuous, with time plotted on the abscissa and alcohol concentration (in ppm) on the ordinate. As shown in Figure 4, the second alcohol sensor reacts completely with alcohol during continuous pumping, resulting in a single peak in the detected alcohol concentration. Figures 3 and 4 show that the peak alcohol concentrations of the first and second alcohol sensors are similar, and the second alcohol sensor recovers faster.

[0057] Figure 5 shows the relationship between the single-response concentration and the actual alcohol concentration of the first alcohol sensor when the first air pump in Figure 2 is an intermittent air pump. This relationship diagram can be calibrated in a laboratory environment, with the actual alcohol concentration (in mg / 100 ml) on the horizontal axis and the single-response concentration (in ppm) on the vertical axis. Assuming the intermittent air pump's pumping time is set to 1 second in a laboratory environment, the sensor's single-response concentration will vary with different pumping times. Multiple sets of data containing single-response concentrations and actual alcohol concentrations can be obtained. By fitting these data, a mapping relationship between the single-response concentration and the actual alcohol concentration can be obtained. Figure 5 shows a relatively ideal linear relationship, but the mapping relationship between the single-response concentration and the actual alcohol concentration varies for alcohol sensors from different manufacturers.

[0058] If the driver has been drinking, both the first and second alcohol sensors will respond after blowing into their breath. Based on the first alcohol sensor's initial response (i.e., the first alcohol concentration) and the pre-set mapping relationship, the driver's actual breath alcohol concentration (i.e., the third alcohol concentration) can be predicted, allowing a timely decision on whether to grant vehicle start permission. The intermittent and continuous air pumps will operate continuously, and the first alcohol sensor will perform multiple incomplete responses. Each response from the first alcohol sensor is compared and analyzed with the fully reacted response from the second alcohol sensor. The resulting alcohol concentration (i.e., the target alcohol concentration) is ultimately displayed on the vehicle.

[0059] During the implementation process, the maximum alcohol concentration among multiple second alcohol concentrations detected by the second alcohol sensor can be determined before the second alcohol sensor reaches saturation; and the target alcohol concentration can be determined based on the third alcohol concentration, the maximum alcohol concentration and the second-to-last first alcohol concentration detected by the first alcohol sensor.

[0060] Assuming the alcohol sensor takes 5 seconds to fully respond to alcohol, and the driver's breathalyzer duration is no less than 3 seconds, the time it takes for the fully reacting second alcohol sensor to detect a response is 8 seconds. The intermittent air pump's pumping time is set to 0.5-1.5 seconds, with a rest period equal to half the pumping time. The shorter the intermittent pump's pumping time, the faster the response time. The continuous air pump continues pumping during the driver's breathalyzer. The flow rates of both the intermittent and continuous air pumps can be set to 200ml / min-400ml / min.

[0061] The multiple response results of the first alcohol sensor must be compared with the real-time response results of the second alcohol sensor. The first alcohol concentration obtained by the first alcohol sensor in each round of detection is set to X1, X2, X3, ...X n-1 、X n The second alcohol concentration detected in real time by the second alcohol sensor is X t The maximum alcohol concentration detected by the second alcohol sensor is X max The third alcohol concentration predicted by the first alcohol concentration X1 is X y .

[0062] The target alcohol concentration is calculated according to the following formula:

[0063] ;

[0064] in, is the target alcohol concentration; is the maximum alcohol concentration; For the third alcohol concentration, The second-to-last alcohol concentration.

[0065] The first alcohol concentrations detected by the first alcohol sensor are X1=10mg / 100ml, X2=40mg / 100ml, X3=80mg / 100ml, X4=130mg / 100ml, and X5=120mg / 100ml, respectively. The maximum alcohol concentration detected by the second alcohol sensor is is 140mg / 100ml, and the third alcohol concentration X1 is obtained by the first alcohol concentration X1. y Taking 138mg / 100ml as an example, the target alcohol concentration can be calculated by the above formula. It is 137.8mg / 100ml.

[0066] In some embodiments, it may be determined that there is alcohol in the driver's oral cavity when the second first alcohol concentration detected by the first alcohol sensor is greater than the first first alcohol concentration detected by the first alcohol sensor.

[0067] It should be noted that after a driver consumes alcohol-containing foods (such as egg yolk pie), alcohol residue is likely to remain in the driver's mouth. Since the alcohol sensor measures the alcohol concentration in the driver's alveoli, if only oral alcohol detection is required, the detection result can be determined based on the first few alcohol concentrations detected by the first alcohol sensor. For example, when X2 > X1 or X3 > X2, the presence of alcohol in the driver's mouth is determined. Using this solution to detect oral alcohol in the driver can yield faster results than the existing method of analyzing the effect curve of a fully reacted alcohol sensor.

[0068] In some embodiments, the first air pump and the second air pump are both continuous air pumps, and the flow rate of gas obtained by the first air pump from the air pipe is greater than the flow rate of gas obtained by the second air pump from the air pipe. Starting and controlling the concentration display of the vehicle according to the first alcohol concentration and the second alcohol concentration may include: starting and controlling the vehicle according to the first alcohol concentration; and controlling the concentration display of the vehicle according to the second alcohol concentration.

[0069] It can be understood that since the flow rate of gas obtained by the first air pump from the blowpipe is greater than the flow rate of gas obtained by the second air pump from the blowpipe, the first alcohol sensor can quickly obtain the first alcohol concentration, and although the second alcohol sensor obtains the second alcohol concentration more slowly, the second alcohol concentration is more accurate than the first alcohol concentration. Therefore, controlling the vehicle start-up according to the first alcohol concentration can achieve quick start-up of the vehicle and avoid the driver waiting for a long time. Controlling the vehicle concentration display according to the second alcohol concentration makes the alcohol concentration displayed by the vehicle more accurate.

[0070] In some embodiments, the flow rate of gas obtained by the first air pump from the blowing tube is greater than or equal to twice the flow rate of gas obtained by the second air pump from the blowing tube. In this way, the response time of the first alcohol sensor will be significantly shorter than the response time of the second alcohol sensor, that is, the first alcohol sensor can obtain the first alcohol concentration more quickly.

[0071] In some embodiments, the first air pump and the second air pump can work simultaneously, or the first air pump can be turned on first and then the second air pump can be turned on after a preset time.

[0072] Figure 6 shows a schematic diagram comparing the response and recovery curves for the first and second air pumps in Figure 2, when both are continuous. The horizontal axis represents time (in seconds) and the vertical axis represents alcohol concentration (in ppm). As shown in Figure 6, the dashed line represents the response and recovery curve for the first alcohol sensor, while the solid line represents the response and recovery curve for the second alcohol sensor. The maximum peak values ​​in the two curves are similar, with the first alcohol sensor exhibiting a slightly faster response and recovery. After the driver drinks alcohol and blows into the air, the first and second air pumps operate simultaneously, and both the first and second alcohol sensors respond. The first alcohol concentration detected by the first alcohol sensor determines whether to grant vehicle start permission, and the second alcohol concentration detected by the second alcohol sensor is then displayed on the vehicle screen.

[0073] Figure 7 shows another comparison of the response and recovery curves for the first and second air pumps in Figure 2, when both are in continuous operation. The horizontal axis represents time (in seconds) and the vertical axis represents alcohol concentration (in ppm). As shown in Figure 7, the dashed line represents the response and recovery curve for the first alcohol sensor, and the solid line represents the response and recovery curve for the second alcohol sensor. The second air pump is turned on 1 second later than the first.

[0074] In this application, the vertical axis ppm of Figures 3, 4, 6, and 7 is the concentration of alcohol gas exhaled by the human body, and the horizontal axis mg / 100ml of Figure 5 is the alcohol content in the blood.

[0075] During the implementation process, after the first air pump is turned on, it can be determined whether the first alcohol concentration is greater than the preset concentration; if the first alcohol concentration is not greater than the preset concentration, the second air pump is not turned on.

[0076] It is understood that when the first air pump is operating, the first alcohol sensor begins to respond. If the first alcohol concentration detected by the first alcohol sensor exceeds a preset concentration, the vehicle is determined to be started based on the first alcohol concentration. After a preset response time, the second air pump is controlled to begin operating, at which point the second alcohol sensor begins to respond, and the second alcohol concentration detected by the second alcohol sensor is output to the vehicle display. If the first alcohol sensor does not detect the first alcohol concentration, or if the detected first alcohol concentration does not exceed the preset concentration, the second air pump is controlled to not operate, the second alcohol sensor also does not respond, the vehicle is directly controlled to start, and the first alcohol concentration is displayed on the vehicle. This method can significantly reduce the frequency of use of the precision-measured second alcohol sensor and the total amount of gas exposed, thereby extending the life of the second alcohol sensor.

[0077] In an embodiment of the present application, when a driver blows into the air tube, a first alcohol concentration detected by a first alcohol sensor via a first air pump connected to the air tube and a second alcohol concentration detected by a second alcohol sensor via a second air pump connected to the air tube are obtained; the vehicle is started and the concentration display is controlled according to the first alcohol concentration and the second alcohol concentration, wherein the first alcohol concentration is different from the second alcohol concentration. By using two different alcohol concentrations to start the vehicle and control the concentration display, not only can the driver's waiting time for driving be shortened and the speed of vehicle startup control be increased, but more accurate detection results can also be obtained. By using the predicted concentration of the first alcohol concentration to correct the second alcohol concentration, the accuracy of the alcohol concentration displayed by the vehicle can be further improved.
