Description

Front and rear interlocking braking warning system {Emergency brake alarm system}

The present invention relates to a sudden braking warning system, and more particularly, warns the danger of sudden braking for all the front and rear areas, and forwards and rearwards to enable a more efficient emergency supply warning by dividing the risk warning step by step according to the state of the sudden braking. The interlocking braking warning system.

In general, when an emergency situation occurs while the driver is driving and the driver momentarily presses the brake pedal, the vehicle is equipped with a brake warning system that informs the driver of the rear vehicle by turning on the brake light provided at the rear of the vehicle. have.

The braking warning system lights up unconditionally when the driver turns the brake light on. Therefore, the driver of the following vehicle must control the speed of his vehicle appropriately according to the flow of the entire vehicle on the road.

However, if the vehicle ahead stops suddenly in a smooth road condition, the driver of the vehicle following the driver sometimes does not cope with it and collides with the vehicle ahead.

Therefore, in case of an emergency or emergency, the driver operates the emergency light switch so that the emergency light flashes repeatedly to inform the driver of the rear vehicle. However, when a very urgent situation arises in which the driver cannot operate the emergency light, the emergency light flashing by the driver's operation is of no use.

In order to solve this problem, recently, when the sudden breakdown situation occurs sudden braking, ABS (Anti-lock Brake System) is automatically recognized when the operation is activated and flashing the emergency light automatically and dangerous to the driver of the surrounding vehicle Braking warning systems are being developed to alert the situation.

However, such a conventional warning device also merely detects the driver's brake pedal operation, and there is a problem in that warning is provided only for the rear vehicle, thereby not providing practical help.

It is an object of the present invention to improve the braking warning system to provide a front and rear interlocking braking warning system for informing the risk of sudden braking not only in the rear but also in front and rear areas according to the road conditions and vehicle conditions.

The front and rear interlocking emergency braking warning system of the present invention is a detection unit for detecting a driving state and a road condition of the vehicle and a control unit for classifying the target direction of the emergency braking warning according to the detection result of the detection unit and warning the danger step by step according to the state of the rapid braking. Include.

The present invention warns the driver of the vehicle in front of the vehicle as well as the rear, and the danger of sudden braking, and by dividing the risk warning step by step according to the state of the sudden braking, it is possible to enable more efficient supply warning.

Preferably, in the front and rear interlocking rapid braking warning system of the present invention, the control unit blinks the emergency light when the deceleration reaches a preset standard in a state in which the traveling speed of the vehicle reaches a predetermined level or is higher than the predetermined level.

Preferably, in the front and rear interlocking rapid braking warning system of the present invention, the control unit operates the anti-lock brake system (ABS) when the running speed of the vehicle reaches a predetermined level or is higher than the predetermined level, and the coefficient of friction is pre-set. The front and rear interlocking braking warning system characterized in that the head lamp flashes when the set condition is satisfied.

Preferably, in the front and rear interlocking braking warning system of the present invention, the control unit operates a horn when the steering variation reaches a reference value while the head lamp is flashing and an obstacle is detected in front.

The present invention warns the driver of the vehicle in front of the vehicle as well as the rear due to sudden braking. Furthermore, the risk warning can be performed in two stages according to the degree of danger, thereby enabling a more efficient supply warning.

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

1 is a block diagram showing the configuration of the front and rear interlocking sudden braking warning system according to the present invention.

Front and rear interlocking sudden braking warning system of the present invention includes a sensing unit 10 and the control unit 20.

The detector 10 detects a driving state and a road condition of the vehicle and transmits the detection result to the controller 20. For example, the sensing unit 10 uses vehicle-mounted sensors to detect vehicle speed, deceleration (G value), steering variation, ABS (anti-lock brake system) operation, road friction coefficient (slip rate). ) And the presence of an obstacle and transmits the detection result to the controller 20.

The control unit 20 determines whether the warning target area is the front or the rear of the vehicle according to the detection result from the sensing unit 10 and controls the warning system to perform a stepwise warning on the warning target direction. For example, the controller 20 flashes the brake light 32 at the rear of the vehicle when the speed and deceleration of the vehicle satisfy the rear braking warning condition, and then increases the deceleration amount so that the emergency braking warning flashes when the emergency light flashing condition is satisfied. Perform the action. In the state where the rear sudden braking warning is made, the control unit 20 blinks the head lamp 38 when the ABS is operated and the friction coefficient (slip rate) satisfies the front braking warning condition. At this time, if the steering fluctuates more than 30 ° (± 30 °) left and right and an obstacle is detected within a certain distance (about 2 m) in front of the front of the vehicle performs a front brake warning operation to operate the horn (horn).

2 is a flowchart illustrating the operation of the front and rear interlocking rapid braking warning system according to the present invention.

While the vehicle is driving, the sensing unit 10 detects the driving speed, deceleration, steering variation, ABS operation, friction coefficient (slip rate) of the road surface, presence of obstacles, and the like through the detection sensors installed in the vehicle. The driving state and the road condition are detected and the detection result is transmitted to the control unit 20 (step 211).

When the driver presses the brake pedal, the control unit 20 provided with the detection result from the sensing unit 10 determines whether the current driving speed and deceleration (the brake amount) of the vehicle satisfy the sudden braking warning condition (step 212).

For example, the controller 20 determines whether or not the brake pedal is stepped in a state where the vehicle traveling speed is 55 km per hour or more. If the sudden braking warning condition is satisfied, the control unit 20 flashes the brake lamp 32 (step 213).

In the state where the brake lamp 32 is blinking, the control unit 20 determines whether the emergency flashing condition in which the speed of the vehicle is rapidly reduced is satisfied (step 214).

For example, the controller 20 determines whether the deceleration becomes 7 kPa or more in a state where the vehicle traveling speed is 55 km / hour or more. If the emergency light flashing condition is satisfied, the control unit 20 flashes the emergency light (step 215).

 As such, the controller 20 performs a rapid braking warning operation to the rear driver by using the vehicle's driving speed and deceleration.

In addition to the rear sudden braking warning operation, the control unit 20 determines whether the front braking warning condition is satisfied in the situation where the sudden braking warning condition in step 213 is satisfied (step 216).

For example, the controller 20 determines whether the ABS is operated and whether the friction coefficient (slip rate) for each road surface state (ice road / snow road / wet road / normal road surface, etc.) satisfies a preset condition. At this time, the slip ratio (%) can be obtained by [(vehicle speed-wheel speed) / vehicle speed] x 100.

If the forward braking warning condition is satisfied, the control unit 20 blinks the head lamp 38 to primarily warn the vehicle ahead of the danger of sudden braking (step 217).

In the state where the head lamp 38 is blinking, the controller 20 determines whether the steering variation amount has reached the reference value (step 218).

For example, the control unit 20 determines whether the steering variation amount is 30 ° (± 30 °) or more from side to side.

If the steering variation amount is 30 ° or more, the control unit 20 determines whether there is an obstacle ahead (step 219).

For example, the controller 20 determines whether an obstacle is present within 2 m in front of the ultrasonic sensor of the detector 10. If there is an obstacle, the controller 20 operates a horn to warn the vehicle ahead of the danger of sudden braking.

Embodiment of the present invention described above is for the purpose of illustration, those skilled in the art will be capable of various modifications, changes, substitutions and additions through the spirit and scope of the appended claims, such modifications and changes are the following claims It should be seen as belonging to a range.

For example, it will be apparent to those skilled in the art that the vehicle speed, deceleration, steering variation, obstacle sensing distance, etc., which are presented as reference values in the above-described embodiments, are presented as preferred embodiments, but are not limited thereto.
