Detailed ways

It should be noted that the embodiments in the present disclosure and the features in the embodiments can be combined with each other if there is no conflict.

Hereinafter, the present disclosure will be described in detail with reference to the drawings and in conjunction with the embodiments.

Fig. 1 is a flowchart of a method for preventing drunk driving provided by an embodiment of the present disclosure. As shown in Figure 1, the method includes:

Step S11, detecting the alcohol content in the driver's body when starting the vehicle and the driver's fingerprint information;

Specifically, the alcohol content in the driver's body can be detected based on an infrared alcohol detection device, which can analyze the alcohol content under the driver's epidermis (more specifically, the alcohol content in the capillaries). Firstly, infrared rays are irradiated on the driver's skin, similar to a low-power flashlight, and then the light enters the skin tissue, and part of the light is reflected back to the skin surface, and a touchpad is used to collect it. The light contains information on skin chemistry, including alcohol concentration information. The device can be installed in any convenient touch position, such as a steering wheel, etc. Preferably, the device can be installed in a position where the driver needs to touch the vehicle to start the vehicle, such as a one-key start touch area on a vehicle with a one-key start function.

Similarly, the device that detects the driver’s fingerprint information can also be installed in the same location as the infrared-based alcohol detection device. For example, the one-key start touch area on a vehicle with a one-key start function can be started when the driver touches a key. Touch area to detect the driver’s fingerprint information and the alcohol content in the driver’s body at the same time when starting the vehicle.

Step S12, detecting the facial information of the driver in real time;

Specifically, the driver’s facial information can be detected in real time by the face recognition system, that is, the driver’s facial information can be detected when the device that detects the driver’s fingerprint information and the infrared-based alcohol detection device perform detection, and then After that, the driver's facial information detection will continue, of course, the facial information detection can also be turned on after the door is opened.

In specific use, take a vehicle with smart key start and one-key start functions as an example. When the driver uses the smart key to open the door after drinking alcohol, that is, the body controller receives the door opening signal, and the body controller sends the signal to the gateway , The gateway forwards the signal to the face recognition system, the face recognition system is activated, and the driver’s cab shooting is started. Face recognition during detection). When the driver first steps on the clutch/brake pedal, the keyless entry and start system (Passive Entry Passive Start, PEPS) immediately starts searching for the key. The user presses the one-key start button, and when the PEPS finds the smart key in the car, the one-key start device that detects the driver's fingerprint information and the infrared-based alcohol detection device simultaneously detect the user.

If the vehicle does not have smart key start and one-key start functions, the face recognition system can also perform face recognition to detect facial information when the door is opened, or the driver touches the location (this position) to detect fingerprints and alcohol content in the body. As described above, facial information can be detected at any location that is convenient for touching.

Step S13, when it is determined that the alcohol content in the body of the driver is greater than the preset content threshold and/or the fingerprint information of the driver does not match the facial information of the driver, control to prohibit the engine of the vehicle from starting.

Specifically, in order to prevent the driver from looking for undrinking passengers to start the vehicle and then drive the vehicle after drinking, the face recognition system can compare the facial information detected in real time with the fingerprint of the person who started the vehicle. When the facial information matches the fingerprint of the person who started the vehicle (that is, the person driving the vehicle is the same as the person who started the vehicle), the engine can be started. When the fingerprint is not detected when the glove is touched), the face recognition system will send a signal to turn off the engine to the gateway, and the gateway will forward the signal. After receiving the signal, the PEPS will switch the system power from ON to OFF, and the EMS will turn the engine from ON. (Engine Run) switch to OFF (Engine Off) state.

Among them, the above-mentioned facial information and fingerprint matching information can be entered in advance.

For example, when a person enters a vehicle for the first time, the face recognition system collects facial information at this time, and if the fingerprint information entry is received within a certain time (for example, 20 seconds), the two are bound and stored. If the fingerprint information entry is not received for a certain period of time, the facial information collected when the person first entered the vehicle is discarded, and the facial information is collected while the fingerprint information entry is received, and bound.

Or, when the vehicle is started for the first time, the driver's fingerprint information is collected (the fingerprint-collecting device can be set in the touch area of the one-key start, or it can be set on the car key), and the driver's facial information is collected at the same time, and the two Binding and storage. In order to prevent cheating by the co-pilot’s personnel starting the vehicle, the weight sensor installed under the co-pilot seat can be used to detect the weight on the co-pilot seat when the vehicle is started for the first time. The weight on the co-pilot’s seat is less than or equal to the expected When setting the weight, the fingerprint information and facial information of the driver are obtained and bound and stored. If the weight on the passenger seat is greater than the preset weight, a prompt message needs to be output to prompt the driver to restart the vehicle.

With the solution of this embodiment, the vehicle cannot be started while wearing gloves. Furthermore, even if a non-drinking person starts the vehicle when starting the vehicle, as long as the drinking driver returns to the driving position, the engine will be prohibited because the facial information detected by the face recognition system does not match the fingerprint when starting the vehicle. start up.

Fig. 2 is a flowchart of a method for preventing drunk driving according to another embodiment of the present disclosure. As shown in Figure 2, the method includes:

Step S21, detecting the alcohol content in the driver's body when starting the vehicle and the driver's fingerprint information;

Step S22, detecting the facial information of the driver in real time;

Specifically, the embodiment of step S21 to step S22 is similar to the above, and will not be repeated here.

In step S23, it is determined that the alcohol content in the driver's body is greater than a preset content threshold, the driver's facial information indicates that the driver is drunk driving, and/or the driver's fingerprint information is different from the driver's fingerprint information. When the facial information does not match, the control prohibits the vehicle engine from starting.

Specifically, in addition to judging whether the driver’s fingerprint information matches the driver’s facial information as described above to prevent the driver from finding undrinking passengers to start the vehicle and then drive the vehicle by himself, this embodiment can also determine the driver’s facial information. Whether it means that the driver is drunk driving to prevent the driver from finding undrinking passengers after drinking alcohol to start the vehicle and then drive the vehicle by himself. Based on this, the facial information of the driver in this embodiment may further include: current eyeball conjunctival information and/or current eye opening information. The facial information indicating that the driver is drunk driving is: the current eyeball conjunctiva information indicates the current eyeball congestion and/or the current eye opening information indicates that the current eye opening is less than a preset opening threshold.

The face recognition system can detect eyeball conjunctival information and/or current eye opening information in real time. When it is recognized that the eyeball conjunctiva is congested and/or the eye opening is less than a preset opening threshold (for example, the person’s face and eyes stored in the database). When the opening is 80%), the face recognition system will send a signal to turn off the engine to the gateway, the gateway will forward the signal, and the PEPS will switch the system power from ON to OFF after receiving the signal, and the engine management system (Engine Management System, EMS) Switch the engine from ON (Engine Run) to OFF (Engine Off) state.

With the solution of this embodiment, even if a non-drinking person starts the vehicle when starting the vehicle, as long as the drinking driver returns to the driving position, the engine will be prohibited from starting due to the facial information detected by the face recognition system.

Fig. 3 is a flowchart of a method for preventing drunk driving according to another embodiment of the present disclosure. As shown in Figure 3, the method includes:

Step S31, detecting the alcohol content in the driver's body when starting the vehicle and the driver's fingerprint information;

Step S32, detecting the facial information of the driver in real time;

Step S33, judging whether the alcohol content in the driver's body is less than or equal to a preset threshold;

Step S34, when it is determined that the alcohol content in the driver's body is less than or equal to a preset threshold, it is determined whether the driver's facial information indicates that the driver is not drunk driving;

Step S35, when it is judged that the driver's facial information indicates that the driver is not drunk driving, it is judged whether the driver's fingerprint information matches the driver's facial information;

Specifically, the embodiments of steps S31-S35 are similar to the above, and will not be repeated here. It should be noted that this embodiment provides a specific method for preventing drunk driving, in which it is determined in order whether the alcohol content in the driver's body is less than or equal to a preset threshold, whether the driver's facial information indicates that the driver is not drunk driving, and Whether the driver’s fingerprint information matches the driver’s facial information, but it is understandable that the judgment order can also be changed. For example, first judge whether the alcohol content in the driver’s body is less than or equal to a preset threshold, and then judge the driver Whether the fingerprint information of the driver matches the facial information of the driver, it is also possible to finally determine whether the facial information of the driver indicates that the driver is not drunk driving, which is not limited in the present disclosure.

Step S36, when it is judged that the fingerprint information of the driver matches the facial information of the driver, control allows the engine of the vehicle to start;

Specifically, the related process of controlling the starting of the vehicle engine may be that the PEPS controls the electronic steering column lock (Electrical Steering Colum Lock, ESCL) to perform unlocking and control the IGN1 relay to pull in. The EMS will be awakened, and the engine anti-theft certification will be initiated after the EMS initialization is completed. After the authentication is successful, PEPS sends a start request signal to the EMS and cuts off the ACC and IGN2 relays at the same time. After the EMS receives the start request signal, it controls the START relay to pull in. The starter starts to run and the EMS controls the engine to inject fuel to start the engine. When the engine starts to run normally, the EMS sends a successful start message to the PEPS, the PEPS reconnects ACC and IGN2 (the IGN1 relay is always on during the start process), and the system power mode switches to ON (Engine Run). If the EMS fails to control the engine to start, the EMS sends a start failure message to the PEPS, and PEPS sets a time limit in the process of switching the system power supply to ON (Engine Off), that is, if the PEPS does not receive the EMS back within the limited time It is a signal for judging whether the engine is started successfully or not, and PEPS switches the system power mode to ON (Engine Off).

In step S37, it is determined that the alcohol content in the body of the driver is greater than a preset content threshold, the facial information of the driver indicates that the driver is drunk driving, and/or the fingerprint information of the driver is similar to that of the driver. When the facial information does not match, the control prohibits the vehicle engine from starting.

Specifically, the embodiment of step S37 is similar to the above, and will not be repeated here.
