Description

Hazard flasher unit in car

The present invention relates to an emergency light lighting device for a vehicle, and more particularly, to an emergency light lighting device for a vehicle to automatically flash the emergency light when braking the car in an emergency.

At present, the front and rear ends of the vehicle are provided with direction indicators and stop lights, which not only indicate the direction of the vehicle but also operate the emergency light switch (or lever) attached to the front control panel of the vehicle or the steering wheel itself. It blinks and serves to inform the driver of the subsequent car of an emergency such as an abnormality or safe driving of the car.

Conventional emergency light lighting device that informs the occurrence of such an emergency state is composed of an emergency light switch 100, an emergency light relay 110 and an emergency light circuit 120, as shown in Figure 1, the driver's emergency light switch 100 The emergency light relay 100 is "on" when "on", and as a result, the emergency light circuit 120 is driven to flash the emergency light.

In addition, the stop light is automatically turned on by the driver's brake operation to inform the driver of the subsequent vehicle that the corresponding vehicle is currently braking.

Therefore, when the braking is made while the vehicle is driving, the stop light is automatically turned on to inform the subsequent vehicle that the corresponding vehicle is currently braking.

However, the stop light that is turned on when the car suddenly brakes in an emergency state during the daytime operation cannot be easily identified by the driver of a subsequent car with a certain safety distance. When sudden braking is performed in a state, it is difficult to easily identify the lighting state of the stop light according to the sudden braking state.

Therefore, when a sudden braking is normally performed during the day or at night, the driver manually operates the emergency light switch to flash the emergency light. However, in the high-speed driving state, the operation of the emergency light switch puts a considerable burden on the driver (especially the novice driver). do.

The object of the present invention is to provide an emergency light lighting device of a vehicle that can alert a subsequent vehicle by automatically flashing an emergency light when suddenly braking in an emergency.

In order to achieve the above object, the emergency light lighting device for a vehicle according to the present invention includes a brake pedal position detecting means for detecting a position of a brake pedal, and a changeable position of the brake pedal is detected by the brake pedal position detecting means. It is characterized in that it comprises a control means for calculating the time taken to change to its position, whether it is sudden braking, and controls the flashing of the emergency light during sudden braking.

Hereinafter, with reference to the accompanying drawings a preferred embodiment of the emergency light lighting device for a vehicle according to the present invention.

2 is a block diagram of the emergency light lighting device of the present invention, in the emergency light lighting device of the vehicle provided with an emergency light switch 100, an emergency light relay 110 and an emergency light circuit 120, to detect the position of the brake pedal A brake pedal position sensor 130; It is configured to include a microprocessor 140 for determining whether the emergency light flashes from the input signal of the brake pedal position sensor 130 and outputs a control signal for emergency light flashing to the emergency light relay (110).

In the emergency light lighting device for a vehicle according to the present invention configured as described above, the brake pedal position sensor 130 detects the position of the brake pedal that is changed according to the driver's stepping on the brake pedal, and sends the information to the microprocessor 140. to provide.

The brake pedal position sensor 130 has contact points A, B, C, and D, which are "on" by the rotation of the brake pedal, at a position obtained by dividing the rotatable range of the brake pedal in several stages. Thus, when the contacts A, B, C, and D are "on", the signal is transmitted to the microprocessor 140.

Then, the microprocessor 140 determines whether it is sudden braking using the position information of the brake pedal input from the brake pedal position sensor 130 and controls the emergency light relay 110 according to the determination result. It demonstrates in detail with reference.

First, the microprocessor 140 performs a routine for detecting the position of the brake pedal from the signal input from the brake pedal position sensor 130 (S100).

The brake pedal position detection routine detects whether the position of the brake pedal is in the " off " state without pedaling or in any of the A, B, C and D positions.

If it is detected that the brake pedal has rotated to the A position in the "off" state, the timer is activated to start counting the time from the moment of detecting the A position, and conversely, if the rotation of the brake pedal to the A position is detected from the B position, the timer is turned off. .

In step S100, it is determined whether the brake pedal has been detected at the maximum brake pedal rotation position D (S101).

If the brake pedal is not detected at the position D as a result of the determination, the process returns to step S100 to detect the position of the brake pedal.

However, as a result of the determination in step S101, if the brake pedal is detected at the D position, it is determined whether the time T taken from the brake pedal to the D position after being detected at the A position is greater than the reference value (S102).

This means that if the driver presses the brake pedal rapidly, the time it takes for the brake pedal to be detected at the A position and then to the D position will be very short. will be.

As a result of the determination in step S102, if the time T from the detection of the brake pedal at the position A to the detection at the position D is greater than the reference value, it is not a sudden braking, and the flow returns to step S100 to detect the brake pedal position again.

However, if it is determined in step S102 that the time taken from the brake pedal is detected at the A position to the detected D position is less than the reference value, it is determined as a sudden braking and outputs a control signal for turning on the emergency light relay 110. The timer is driven (S103, S104).

When the emergency light relay 110 is "on" by the control signal output from the microprocessor 140, the emergency light circuit 120 is driven to flash the emergency light.

Thus, the stop light that is turned on when the vehicle suddenly brakes during an emergency during the daytime operation was not easily discernible by the driver of the subsequent vehicle, and when the vehicle suddenly brakes while the vehicle is turned on during night driving. The problem that the lighting state of the stop light according to the sudden braking state was not easily discernible is solved.

When the timer for counting the "on" time of the emergency light relay 110 reaches a reference value, the control signal for "turning off" the emergency light relay 110 is output, and the emergency light relay 110 is "off" to thereby turn off the emergency light circuit 120. The operation of the emergency light that was flashing by the operation is stopped, and the object of the present invention is to achieve the purpose of flashing the emergency light only for a predetermined time during sudden braking (S105, S106).

In this way, apart from the flashing of the emergency light automatically during sudden braking, the driver may flash the emergency light by operating the emergency light switch 100 to notify a subsequent car of an emergency even when the emergency braking is not performed.

As described above, the emergency light lighting device of a vehicle of the present invention includes a brake pedal position detecting means for detecting a position of the brake pedal, and when the maximum rotational position of the brake pedal is detected by the brake pedal position detecting means, the position changes to the position. Determines whether it is sudden braking as the time taken, and has control means for controlling the flashing of the emergency light during sudden braking, and automatically flashes the emergency light during sudden braking to reduce the burden of operating the emergency light switch when the driver suddenly brakes in an emergency state. It has the effect of preventing crash accidents by increasing the alarm effect during sudden braking.
