As shown in fig. 4 and 5, the gas cylinder 31 is preferably mounted on the back of the spoke 11 of the steering wheel 1, so that the gas cylinder 31 is less affected by external heat sources such as sunlight, is safer, and can not hurt a driver even if an accident such as explosion occurs, and the shielding of the metal skeleton is avoided. Further, the first opening/closing valve 421, the second opening/closing valve 431, the pressure sensor 411 and other structures can utilize the circuit interface of the original functional assembly in the vehicle to solve the power supply and electrical communication problems, and establish electrical connection with the vehicle fatigue reminding system through the electrical connection of the original steering wheel 1 and the instrument panel, thereby realizing cooperative work.
The embodiment of the application also provides a vehicle fatigue reminding method which adopts the vehicle fatigue reminding system and is characterized by comprising the following steps of controlling the first opening and closing valve 421 to be opened when the fatigue driving of a driver is monitored, so that gas in the gas storage mechanism 3 is sprayed to the driver through a circulation pipeline. The fatigue driving of the driver can be monitored by adopting an original fatigue monitoring system on the vehicle, such as adopting an imaging device to shoot facial information of the driver, and judging that the fatigue driving occurs when the conditions such as yawning are found. After the opening of the first on-off valve 421 is controlled, the gas having a certain pressure in the gas cylinder 31 is blown to the driver through the main pipe 41 to the first branch pipe 42 and finally to the release pipe 21.
Furthermore, the vehicle fatigue reminding method in the embodiment of the application also should read the current vehicle speed control signal according to the past vehicle speed signal, namely the whole vehicle ECU, and only when the vehicle speed is not 0, the odor reminding function is started after the driver fatigue driving is judged. In addition, the smell reminding function can work in cooperation with other fatigue reminding functions, the other fatigue reminding functions can adopt one or two reminding modes of sound (such as sending out a drop and a sound), an optical signal (an indicator lamp flashes) or vibration (a seat and/or a steering wheel built-in vibration motor), when the driver is monitored to perform fatigue driving, the other fatigue reminding functions except the smell reminding are started first, if the other fatigue reminding is repeated for three times (such as 15 minutes) in a period of time, the driver is monitored to be still in fatigue driving again next time, and in the embodiment of the application, the driver can be reminded in multiple directions by matching the smell reminding with the other fatigue reminding, so that the driver can be kept in a clear state as much as possible, and the driving safety is enhanced.
Preferably, when the smell reminding function is started, the gas injection can be performed in a pulse mode, the injection time is 0.1 s-0.2 s each time, the state of a driver is continuously monitored after the injection, and if the driver is still in a fatigue and sleepiness state, the next injection is started. The spraying interval time is not less than 15s, and the spraying is performed for 3 times at most. After the gas jet is started, the conventional reminder (sound, light, vibration) should be kept in a continuous working state. If the driver is still detected to be in a fatigue state after 3 times of gas injection, follow-up measures such as automatic side parking (for a vehicle with an automatic driving function), notification of relevant parties (including but not limited to police, relatives and fleet managers, in a mode of telephone/short message/mobile phone APP message) and the like are taken. When the pressure in the gas cylinder 31 is low enough to support injection, a fault code is sent to the driver by the meter, prompting replacement of the gas cylinder 31, while disabling the scent reminding function.
In some alternative embodiments, the circulation pipeline includes a main pipeline 41 and a first branch pipeline 42 connected to the main pipeline 41, the main pipeline 41 is further connected to a second branch pipeline 43 connected to the first branch pipeline 42 in parallel, the first on-off valve 421 is installed on the first branch pipeline 42, the first branch pipeline 42 is connected to the main pipeline 41 and the gas release mechanism, and the vehicle fatigue reminding method may further include monitoring a pressure value of the gas storage mechanism 3 in real time and comparing the monitored pressure value with a preset pressure value, and controlling the second on-off valve 431 installed on the second branch pipeline 43 to open when the pressure value of the gas storage mechanism 3 is greater than the preset pressure value, so that the gas storage mechanism 3 is communicated with the outside. The real-time monitoring of the pressure value of the gas storage mechanism 3 may be that a pressure sensor 411 is installed at the main pipeline 41, the pressure sensor 411 is connected with the whole vehicle ECU through signals, and the change of the pressure value in the gas storage mechanism 3 can be obtained, it should be understood that if the gas in the gas storage bottle 31 needs to be released to act on the driver, the gas is released, in the process, the pressure value in the gas storage bottle 31 should be in a reduced state, therefore, when the pressure value of the gas storage mechanism 3 is greater than a preset pressure value, the first opening and closing valve 421 and the second opening and closing valve 431 can be both in a closed state before the pressure value of the gas storage mechanism 3 is greater than the preset pressure value, which may mean that the pressure of the gas storage bottle 31 is abnormally increased, and at the moment, a fault code can be sent to the driver through an instrument, so that the driver is promoted to pay attention to remove the fault. If the pressure sensor 411 detects that the pressure value rises to a dangerous state, in order to ensure the safety of the environment in the vehicle, the pressure is actively released, at this time, the vehicle ECU may control the second on/off valve 431 to be opened, and the first on/off valve 421 is still closed, so that the gas in the gas storage bottle 31 is discharged from the second on/off valve 431 to the outside of the vehicle.
In some alternative embodiments, the vehicle fatigue reminding method may further include monitoring the pressure value change condition in the gas storage mechanism 3 in a preset time in real time when the first on-off valve 421 is in a closed state, controlling the second on-off valve 431 to open if the pressure value is gradually reduced so as to enable the gas storage mechanism 3 to be communicated with the outside, and controlling the second on-off valve 431 to close if the pressure value is not gradually reduced. The whole vehicle ECU can continuously monitor the change condition of the pressure value in the pressure sensor 411, when the first on-off valve 421 is closed, the smell reminding function is not started, but the value in the pressure sensor 411 continuously drops, so that the risk of gas leakage in the gas storage bottle 31 or the circulation pipeline can be considered, adverse effects can be caused to a driver, in order to reduce the influence of the gas leakage on the driver, the pressure release function is started at the same time, the second on-off valve 431 is opened, the first on-off valve 421 is continuously closed, and the residual gas flows out of the vehicle from the main pipeline 41 through the second branch pipeline 43.
Further, when the whole vehicle safety airbag is ignited and unfolded, the whole vehicle ECU determines that a traffic accident occurs in the vehicle, and in order to prevent the gas storage bottle 31 as a pressure container from being squeezed to generate danger, the whole vehicle ECU actively releases pressure, and controls the second opening and closing valve 431 to be in an open state, and the first opening and closing valve 421 to be in a closed state, so that gas in the gas storage bottle 31 flows to the outside of the vehicle through the hose 44, i.e. flows out of the passenger cabin.
