Fig. 2A is a flowchart of a vehicle control method according to an embodiment of the present invention, and referring to fig. 2A, the method includes the following steps.
Step 201: the vehicle detects an alcohol concentration inside the vehicle.
Wherein, when the vehicle detects that the power of the vehicle is turned on, the alcohol concentration inside the vehicle may be detected by an alcohol sensor mounted on the vehicle.
It should be noted that when the vehicle detects that the power is turned on, the vehicle may be running or may be just ready to run but not start running, that is, the vehicle may detect the alcohol concentration inside the vehicle during running of the vehicle or may detect the alcohol concentration inside the vehicle before the vehicle starts running. In practical applications, in order to further improve the accuracy of drunk driving detection, the vehicle may perform the alcohol concentration detection once before driving, and continue the alcohol concentration detection once during driving.
In addition, in order to ensure that there is sufficient time to detect the alcohol concentration inside the vehicle before the vehicle travels, the vehicle may be detected within a specified period of time while the power is on. During the running process of the vehicle, the alcohol concentration in the vehicle can be detected once at specified time intervals or continuously. The specified time period may be set in advance, for example, the specified time period may be 1 minute, 2 minutes, or the like. The specified time interval may also be set in advance, for example, the specified time interval may be 2 minutes, 5 minutes, and the like.
Step 202: when the alcohol concentration in the vehicle is greater than the preset alcohol concentration, sequentially performing alcohol lock control operation and alcohol test operation, wherein the alcohol lock control operation is used for controlling the vehicle to stop running, and the alcohol test operation is used for detecting whether a driver of the vehicle drives drunk.
It should be noted that the preset alcohol concentration may be set in advance, for example, the preset alcohol concentration may be 10%, 20%, and so on.
When the alcohol is not detected to exist in the vehicle or the alcohol concentration is detected to be less than the preset alcohol concentration, it indicates that the driver of the vehicle is not drinking alcohol, and at the moment, the vehicle can start to run or continue to keep a running state. When the alcohol concentration in the vehicle is higher than the preset alcohol concentration, the driver of the vehicle is possibly in risk of drunk driving, and therefore, in order to avoid traffic accidents, the vehicle can sequentially perform alcohol lock control operation and alcohol test operation. The following explains the alcohol lock control operation and the alcohol test operation of the vehicle, respectively.
Performing control operation of alcohol lock
As described above, when the vehicle is powered on, the vehicle may be in the ready-to-run state or in the running state, and the alcohol lock control operation performed in the ready-to-run state of the vehicle and the alcohol lock control operation performed in the running state are different from each other.
In the first case, when the engine of the vehicle is not operated and the vehicle speed of the vehicle is 0, the vehicle is in the ready-to-travel state at this time. Since vehicles can be classified into fuel vehicles and electric vehicles. Therefore, if the type of the vehicle is a fuel-powered vehicle, the starter of the vehicle may be controlled not to start, and if the type of the vehicle is an electric vehicle, the vehicle may be controlled to stop the power output.
It should be noted that, after the vehicle is stopped and the vehicle is started, the following alcohol test operation may be performed.
In the second case, when the engine of the vehicle is running and the vehicle speed of the vehicle is not 0, it indicates that the vehicle is in a running state, and since the vehicle can be divided into a fuel vehicle and an electric vehicle, the fuel vehicle needs to use the combustible gas mixture to burn to do work, and the electric vehicle needs to use the power output of the vehicle. Therefore, if the type of the vehicle is a fuel vehicle, the air intake amount of the vehicle is controlled to be reduced to a preset value, and if the type of the vehicle is an electric vehicle, the power output of the vehicle is controlled to be reduced to a preset power.
Since the vehicle may be in a position where the vehicle cannot be parked during driving, if the vehicle is directly controlled to be parked, a traffic accident may be caused. Therefore, in order to avoid causing traffic accidents, the vehicle can be controlled to reduce the running speed, and then the driver is prompted to find a proper position to stop.
When the type of the vehicle is a fuel vehicle, the air intake amount of the fuel vehicle is controlled by a throttle valve, and the throttle valve can be controlled by a pedal or an EMS (Engine Management System). When the throttle valve is controlled by a pedal, the throttle valve can be controlled by a user stepping on the pedal, therefore, in order to ensure that the vehicle speed can be reduced, a throttle valve controlled by a starting controller of the vehicle can be added into the vehicle, and referring to fig. 2B, the opening and closing of the added throttle valve can be controlled by the starting controller to control the air in an air inlet pipe to enter the vehicle, so that the air inlet quantity of the vehicle is reduced to a preset value. When the throttle is controlled by the EMS, referring to fig. 2C, the opening and closing of the throttle may be controlled directly by the ESM.
In addition, when the type of the vehicle is an electric vehicle, since the power output of the electric vehicle is controlled by the energy management system, the power output of the vehicle can be directly controlled by the energy management system.
It should be noted that the preset value may be preset, for example, the preset value may be 100 g/s, 50 g/s, etc., and the preset power may also be preset, for example, the preset power may be 1 kw, 2 kw, etc.
Further, in the embodiment of the invention, the vehicle may control the intake air amount to be decreased to a preset value, or control the power output to be decreased to a preset power, or may control the intake air amount in accordance with the running speed of the current vehicle so that the controlled running speed becomes 1/2, 1/3, 1/5, etc. of the current running speed.
Further, since the driver may be unconscious when drunk driving, the driver may still drive the vehicle at a low speed and not stop the vehicle when the vehicle is alcohol lock controlled, and there is still a risk of traffic accidents. Therefore, in order to avoid the occurrence of a traffic accident, after the vehicle performs the alcohol lock control operation, if the engine of the vehicle does not stop operating within a preset time period and the vehicle speed of the vehicle is not 0, the drunk driving information of the vehicle is transmitted to the target network device, which is a device capable of communicating with the vehicle.
It should be noted that the preset time period may be set in advance, for example, the preset time period may be 3 minutes, 5 minutes, and so on.
In addition, the target network device may be a system management device of a traffic management department, or a management device of a service station of a business to which the vehicle belongs, or a terminal used by a driver's relatives and friends preset for the vehicle, or the like.
Performing alcohol testing operation
When the alcohol concentration in the vehicle is higher than the preset alcohol concentration, the alcohol concentration may be caused by other drinkers in the vehicle, but not by the driver. Therefore, in order to improve the accuracy of drunk driving detection, after it is determined that the vehicle stops running, an alcohol test operation may be performed to determine whether the driver has drunk alcohol.
It should be noted that the alcohol test operation includes at least one of a prompt test operation, a preparation test operation, a touch screen test operation, a steering wheel test operation, and a brake application test operation.
Wherein, the vehicle can carry out a plurality of test operations including the alcohol test operation in turn; when any one of a plurality of test operations included in the alcohol test operation fails, determining that the driver of the vehicle fails the alcohol test operation, and stopping starting the rest of the alcohol test operations; when it is determined that each of a plurality of test operations included in the alcohol test operation passes, it is determined that the driver of the vehicle passes the alcohol test operation.
For example, when the alcohol test operation includes a prompt test operation, a preparation test operation, a touch screen test operation, a steering wheel test operation, and a brake test operation, if the user passes the prompt test operation, the preparation test operation is continued, if the user continues to pass the preparation test operation, the touch screen test operation is continued, if the user fails to pass the touch screen test operation, it is determined that the user fails the alcohol test operation, and the steering wheel test operation and the brake test operation are stopped from being started.
It should be noted that the vehicle may also detect whether the driver is drunk by only one of the alcohol test operations. However, when drunk driving detection is performed only through one test operation of the alcohol test operations, a driver is likely to pass the test by coincidence, and traffic accidents may occur when the subsequent driver continues driving. Therefore, in order to improve the accuracy of drunk driving detection and the safety of driving, the vehicle needs to sequentially perform a plurality of test operations including the alcohol test operation, and when any test operation fails, it is determined that the driver fails to pass the alcohol test operation, and thus it is determined that the driver is drunk driving.
In addition, in the embodiment of the present invention, the sequence of the plurality of test operations performed by the vehicle in sequence may be set in advance, for example, the sequence may be a prompt test operation, a preparation test operation, a touch screen test operation, a steering wheel test operation, and a brake application test operation, or may also be a prompt test operation, a preparation test operation, a steering wheel test operation, a brake application test operation, and a touch screen test operation.
Furthermore, the way in which the vehicle sequentially performs a plurality of test operations included in the alcohol test operation may be: determining whether a control operation responding to a target test operation is detected within a response duration of the target test operation when the target test operation is performed, the target test operation being any one of a plurality of test operations included in the alcohol test operation; determining that the driver of the vehicle passes the target test operation when a control operation responding to the target test operation is detected within the reaction period of the target test operation; when a control operation in response to the target test operation is not detected within the reaction period of the target test operation, it is determined that the driver of the vehicle fails the target test operation.
It should be noted that, in the vehicle, a corresponding response time period may be set in advance for each test operation in the alcohol test operation, where the response time period refers to a time period for a driver to respond to the corresponding test operation, for example, the response time period may be 5 seconds, 10 seconds, 30 seconds, and the like, and the response time periods of each test operation may be the same or different. In addition, the control operation in response to each test operation may also be set in advance, and each control operation is different. Meanwhile, the number of times each test operation is performed can be set in advance, and when each test operation passes, it is determined that the driver of the vehicle passes the test operation. For example, the touch screen test operation may be set to be performed 3 times, and if all of the 3 tests pass, it is determined that the driver of the vehicle passes the touch screen test operation.
In addition, when it is determined that the driver of the vehicle fails the target test operation, drunk driving information may be fed back to the target network device, or drunk driving information may be prompted to the driver.
The following description will be made of the alcohol test operation by taking a prompt test operation, a preparation test operation, a touch screen test operation, a steering wheel test operation, and a brake application test operation, which are included in the alcohol test operation, as examples.
(1) Prompt test operation
