To prevent drowsy driving prevention and safe driving induction apparatus.

Generally, when a driver drives a vehicle for a long time, the driver may feel tired and even drowsy driving. The drowsy driving of the driver causes a large accident. In other words, drowsy driving is a dangerous behavior that threatens the life of not only the driver but also the passenger and the occupant.

Therefore, for safe driving of the vehicle, it is necessary to periodically ventilate the indoor air to prevent drowsiness and to release fatigue through sufficient rest, and above all, the driver himself must have a firm will for safe driving.

However, a bus or a truck that regularly runs a predetermined section cannot take sufficient rest as it has to arrive at the destination within the designated time. Therefore, there are cases where the driver of a bus or a truck performs drowsy driving or overspeed driving, but conventionally, there is no method for preventing such drowsiness driving and overspeed driving.

In addition, an incorrect driver's posture, such as a driver's foot on the driver's seat or even a driver's foot on a dashboard with dashboards, could cause an accident.

The present invention has been invented to solve the above problems, not only to relieve driver fatigue, but also to prevent drowsy driving, to prevent overspeed of the vehicle, and to induce a correct driver's posture, resulting in accidental accidents. It is an object of the present invention to provide a device for preventing drowsy driving and driving a safe operation to prevent damage and loss of property.

In order to achieve the above object, the present invention, in a general vehicle, a vehicle speed sensor for outputting a pulse signal corresponding to the traveling speed of the vehicle, a foot switch mounted on the driver's side of the driver's seat (foot), A massage motor mounted on a separate mat or driver's seat and exerting a shock when the driver drows, speeds, or feels tired, and an input signal and the vehicle speed applied according to the flow of the accelerator pedal, the brake pedal, and the foot switch.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram schematically illustrating a safe driving guidance apparatus according to the present invention, in which an accelerator pedal 10 and a brake pedal 20 for accelerating or braking a vehicle in operation are connected to a controller 50. Therefore, when the accelerator pedal 10 and the brake pedal 20 flow, a signal corresponding thereto is applied to the controller 50.

In addition, the vehicle speed sensor 40 for outputting a pulse signal corresponding to the vehicle traveling speed is connected to the control unit 50, the control unit 50 is the driving speed of the vehicle through the pulse signal output from the vehicle speed sensor 40 In addition to detecting the driver's driver's posture, that is to say whether drowsy driving.

In addition, a foot switch 30 is connected to the control unit 50. In general, when the driver is driving in an excessively comfortable position, the foot switch 30 as shown in FIG. In the case of the left side of the pedal 80 and the automatic transmission vehicle, it is mounted on the left side of the brake pedal 20 so as to step on the driver.

The foot switch 30 is mounted to induce the driver to have a correct driver posture, in order to prevent the driver from driving with his foot on the driver's seat or dashboard. It is not operated if it is placed and it is configured to operate when a predetermined pressure is applied.

On the other hand, a large number of massage motors 60a to 60n are connected to the control unit 50 to shock the driver when the driver is dozing or speeds up and to give alarm to the safe driving of the vehicle or to release the driver's fatigue. The massage motors 60a to 60n are mounted in plural so as to impact the neck, shoulder, waist and thigh of the driver.

That is, the massage motors 60a to 60n as shown in FIG. 3 are mounted on a separate mat 90 installed in the driver's seat or directly mounted on the driver's seat 110 as shown in FIG. 4, and the mat 90 ) Or seat 110 is a heating wire 100 is built to keep the body of the driver in winter.

In addition, instead of the massage motors 60a to 60n described above, warning lights or alarms for generating an alarm sound may be mounted to give alarm regarding safety driving of the vehicle.

In addition, the controller 50 comprehensively inputs an input signal applied according to the flow of the accelerator pedal 10, the brake pedal 20, and the foot switch 30 and the input signal applied from the vehicle speed sensor 40. The controller 50 drives the massage motors 60a to 60n mounted on the mat 90 or the driver's seat 110 to determine whether the driver is drowsy and to wake the driver during the drowsy driving. Shock the driver.

In addition, the controller 50 does not need to operate a separate operation switch when the driver in sleepy driving wakes up according to the driving of the massage motors 60a to 60n and brakes the vehicle to prevent a collision with the vehicle ahead. 70) is automatically activated to shorten the braking distance of the vehicle.

Next will be described in detail with reference to Figure 5 the operation method of the safe driving guidance apparatus according to the present invention configured as described above.

The safe driving guidance apparatus according to the present invention does not operate when the vehicle travels below 60 km (101). That is, when the vehicle is congested, driving is rarely drowsy, and even when a collision occurs at a driving speed of 60 km or less, the damage is minor, so the safe driving induction device is not driven.

In addition, even when the foot switch 30 is pressed, the driver determines that the vehicle is normally driven and does not drive the massage motors 60a to 60n (102). However, when the driver drives the vehicle at a speed, for example, when driving the vehicle at 105Km or more, the motor 60a to 60n for massage is driven to give the driver a warning about the speed (103). At this time, since the driver may be surprised when a sudden strong shock is applied, the controller 50 controls the driving of the massage motors 60a to 60n so that the strong shock can be gradually applied to the driver from the weak shock.

On the other hand, even when the vehicle is braking, the driver judges that the vehicle is normally driven and does not drive the massage motors 60a to 60n (109). However, if the driver presses the brake pedal 20 while the vehicle is driving at 10 km or more (104, 107), the brake brake 70 is operated by operating the exhaust brake 70 together without driving the separately mounted operation switch ( 108).

This is when the driver who is drowsy driving wakes up by the driving of the massage motors 60a to 60n and brakes the vehicle in order to prevent a collision with the vehicle ahead. In order to prevent the collision of the vehicle by automatically driving this as there is no.

In addition, when the vehicle is driving within 60 km to 105 km, the foot switch 30 is off and the vehicle is not braking, it is determined whether the driver has changed the driving speed of the vehicle by operating the accelerator pedal 10 within 5 seconds. (105). This can be detected through the switching state of the ultrasonic sensor or the proximity switch interlocked with the accelerator pedal 10, and also the change in the number of pulses or the change in the pulse width or the speed change made for 5 seconds from the vehicle speed sensor 40 If the change is small, it is determined that the driver is drowsy driving, and the controller 50 drives the massage motors 60a to 60n (106). On the other hand, if the change is large, the driver determines that the vehicle is normally driven and does not drive the massage motors 60a to 60n (109).

On the other hand, when the vehicle is at a standstill or when the driver feels tired, the control unit 50 may perform massage motors 60a to 60n unless the driver changes the running speed of the vehicle without stepping on the foot switch 30. It stimulates the driver's neck, shoulders, waist and thighs to relieve fatigue. In addition, a separate manual switch can be provided to directly drive the motors 60a to 60n for massage.

As described above, the present invention is equipped with a massage motor on a separate mat or the driver's seat itself mounted on the driver's seat, and when the driver is overspeed or drowsy driving or feels tired, driving the motor for the massage for safe driving of the vehicle. It also raises awareness and relieves driver fatigue, protecting people and property from drowsiness, overspeed driving and accidents caused by incorrect driving posture.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Therefore, the true technical protection scope of the present invention should be defined only by the appended claims.
