Description

BRAKE INTENSITY INDICATOR
FIELD OF THE INVENTION
The present invention generally relates to a system for detecting the braking of a vehicle, and more particularly to the system which detects braking based on the light emitted from the rear lights of the vehicle, which can be controlled by the driver using various mechanisms.
BACKGROUND AND PRIOR ART
The vehicle which is currently in use has a braking system that includes brake lights and the brakes which when are applied by the driver, the brake lights willbe illuminated on the rear end of the vehicle. The driver presses the brakes, and in response to the actuating of the brake pedal, the brake lights glow and the vehicle comes to a halt due to a reduction of speed. When the driver of the vehicle applies the brake, the other vehicles which are on road right behind the said vehicle will be warned and they can immediately decide to slow down.
The advancement of the technologies the vehicles have led to t h e usage of various braking systems. Most modem vehicles have brakes on all four wheels which are operated mainly by a hydraulic system. The brakes operated by the hydraulic system can wither disc type or drum type. As brakes are located on all four wheels, the front brakes play a greater part in stopping the car than the rear wheel brakes, because braking throws the car weight forward onto the front wheels. The modernization of vehicles has also improved the braking performance of the vehicles, which also involves using electronic systems. The brake lights glow at the rear end of the vehicle even when the brake pedal is applied slightly. Also, there is no way for the other vehicles that are on the tail of the said vehicle to know how hard the brake pedal is pressed, which can prove to be a problem to the other drivers as they can see only the illumination of the brake lights but not how strongly the vehicle brake pedal was applied. Due to this, the vehicles which are behind cannot know the situation which the vehicle driver is facing so that they can decide to brake hard. There are several prior art patents that provide various methods for indication of hard brakes.
US patent application 9387798B2 discloses a system for vehicle braking detection of a vehicle may include a device provided in a first vehicle. The device may be in communication with a detector mounted to the first vehicle to monitor an area in front of the first vehicle. The detector may detect light emitted by the rear lights of a second vehicle when the second vehicle is ahead of the first vehicle in the monitored area. The device may acquire data from the detector and analyze the acquired data in order to detect an optical signal emitted by the rear lights of the second vehicle. The optical signal may encode information indicative of a braking procedure being performed by the second vehicle. The device may evaluate the detected optical signal in order to derive the information indicative of the braking procedure of the second vehicle.
US patent application 8587424B2 discloses vehicle regenerative deceleration actuator and indicator system for regenerative slowing of a hybrid or electric vehicle includes at least one regenerative-only deceleration indicator positioned on the rear ofa vehicle in addition to the conventional vehicle brake lights, a vehicle deceleration monitor configured to monitor deceleration of the vehicle and produce a control output signal if deceleration exceeds a predetermined level, a vehicle braking module configured to detect application of the conventional vehicle brakes, and an indicator control module configured to actuate the regen-only deceleration indicator whena vehicle deceleration output signal exceeding the predetermined level is received andthe conventional vehicle brakes are not applied. An independent driver-operated regen mode switch may provide for driver-initiated regen slowing independent of the conventional vehicle brakes or gears, with the regen-only deceleration indicator being on when regen mode is initiated by the driver without application of the frictio brakes, and the predetermined deceleration level is exceeded.
US patent application 10127816B2 discloses detection and alert of automobile braking event which alerts a driver of a driven vehicle about an unsafe traffic condition. The method detects ,by one or more of a radar detector, a Light Detection and Ranging (LIDAR) detector, or a camera, a braking event of a nearby vehicle. The method stores, in a storage device, the braking event of the nearby vehicle. The method communicates a signal indicative of the braking event of the nearby vehicle to a brake system of the driven vehicle. The method also alerts the driver, by one or more of a user display alert or an audible alert, of the braking event of the nearby vehicle.
The issues which are faced by the vehicle drivers are trying to be solved by the vehicle manufacturers and other innovators, by including several visible indications through the rear lights, which can be through flashing of the brake lights or the hazard flashers, or increasing the brightness of brake lights or addition of an extra light indicator or so forth. But these systems are not caught or recognized immediately by the drivers which are behind, which can lead to collisions. The prior arts which are mentioned above are complex and some require changes and installations to be done in the car mechanics to detect the brake strength.
Therefore, there is a need for an advanced system which can be installed universally, which specifically helps the drivers to avoid rear end collisions of the vehicles by clearly indicating the drivers when the hard brake is applied.
OBJECTS OF THE INVENTION
The primary object of the present invention is to provide an advanced braking system with brake intensity indicator which can indicate the drivers through the indicators on the rear end of the vehicle.
Another object of the present invention is to provide a brake intensity indicator system where the activation of the indicators can be done through laser device located at the bottom of the brake pedal of the vehicle.
Another object of the present invention is to provide a brake intensity indicator system where the activation of the indicators can also be done through the pressure sensor devices installed under the brake pedal. SUMMARY OF THE INVENTION
The present invention discloses a braking intensity indicator system comprising of the indicators located on the rear end of the vehicle in the form of LED strips which can be activated through different systems which can include laser devices. According to the present invention, the braking system includes the trigger mechanisms like laser devices which are in connection with a push-button specifically installed below the brake pedal which when pressed only with a certain force, such as hard brake, where the brake pedal comes in contact with the push button, activating the indicators or LED strips on the rear end of the vehicle which are specific for the hard brake. The system is controlled by a microcontroller, which controls the time of activation of the LED lights. The microcontroller maintains the duration of indication i.e., the total time of flashing the LED light strip, where the said LED lights glow for a set amount of time when the vehicle driver applies hard to break.
An additional embodiment of the present invention discloses the use of pressure sensors as the triggering mechanism. With the use of the pressure sensors as the triggers, where the pressure sensors are installed at the bottom of the brake pedal which when pressed hard, activates the indicators on the rear end of the vehicle.
According to the present invention, this method of using the indicators at the rear end of the vehicle makes it possible for automatic indication of the application of the hard brakes, which can help the other vehicles which are behind the said vehicle to immediately decelerate and coming to a halt. As separate indicators are used for relaying the information to the other vehicles about the hard braking or immediate deceleration, the reaction time can be greatly reduced. The braking system of the present invention is specifically developed for the indication of vehicle brake detection, which highly improves the process and efficiency of warning the other drivers behind the said vehicle which leads to prevention of rear-end collisions. Also using the present invention, the indicator lights which are used for indicating the other vehicles about the hard brake, the following vehicles can benefit from knowing about braking immediately which can avoid vehicular damage for them too. It should be understood that the features mentioned above and those yet to be explained below can be used not only in the respective combinations indicated, but also in other combinations or in isolation. To the people skilled in the art, the systems, methods and other components and their combination of the same for usage will be apparent.

In another embodiment of the present invention, the pressure sensor located below the brake pedal (4) identifies the application of hard brake or emergency brake when the threshold of 50% is reached, which is when the pressure applied on the brake pedal (4) by the driver is above the threshold level.
In another embodiment of the present invention, the indication of the brake strength bythe vehicle is through the illumination of the lights from the assembly of LED lights. In another embodiment of the present invention, the duration of illumination of the LEDlights on the LED strip (1) is controlled by the microcontroller (3) ranging from 2 seconds to 10 seconds.
According to the present invention, this method of using the indicators at the rear end of the vehicle makes it possible for automatic indication of the application of the hard brakes, which can help the other vehicles which are behind the said vehicle to immediately decelerate and coming to a halt. As separate indicators are used for relaying the information to the other vehicles about the hard braking or immediate deceleration, the reaction time can be greatly reduced.
The present invention can be understood in detail with the help of examples:
Example 1: In case of any person or an animal accidentally coming in front of the vehicle which requires the application of hard brake or emergency brake by the driver, then the push button 2 is pressed by the driver by pressing the brake pedal 4 to the maximum, which immediately activates the LED indicator lights on the LED strip 1 located on the rear end of the vehicle. The microcontroller 3 controls the activation of the LED lights on the LED strip 1 where the said LED lights glow for 4 seconds, which can be detected by the following vehicles. This indicates the following vehicles to immediately stop or reduce the speed of their vehicles to avoid rear-end collision.
Example 2: In case of any person or an animal coming in front of the vehicle, or in case of any accidents which happened on the busy road which requires application of hard brake or emergency brake by the driver, then the brake pedal 4 is pushed to an extent which goes beyond the threshold (75%), which immediately activates the LED indicator lights on the LED strip 1 located on the rear end of the vehicle. This indicates the following vehicles to immediately stop their vehicles to avoid rear-end collision.
Example 3: In case driver A is traveling on a road having more than one hairpin bend where the preceding vehicle visibility is very low, driver A can make use of the brake intensity indicator system in case of accidents or landslides, where the application of hard brake or emergency brake is a must, then the push button 2 is pressed by the driver A by pressing the brake pedal 4 to the maximum, which immediately activates the LED indicator lights on the LED strip 1 located on the rear end of the vehicle. The microcontroller 3 controls the activation of the LED lights on the LED strip 1 where the said LED lights glow for 10 seconds, which can be detected by the following vehicles. This indicates the following vehicles to immediately stop or reduce the speed of their vehicles to avoid rear-end collision.
Example 4: In case of a driver B travelling in snow areas where roads are slippery and visibility due to snow is hazy, then the driver can apply hard brake in case of emergencies during accidents or a pile-up, by pressing the brake pedal 4 to the maximum extent which pushes the push button 2 to immediately activate the LED indicator lights on the LED strip 1 located on the rear end of the vehicle, for a set amount of time. The microcontroller 3 controls the activation of the LED lights on the LED strip 1 where the said LED lights glow for 7 seconds, which can be detected by the following vehicles. This indicates the following vehicles to immediately stop or reduce the speed of their vehicles to avoid rear end collision.
Accordingly, using these indicator systems, the preceding vehicle which flashes the indicator lights for the emergency brake, providing the optical signal through the LED lights, does not require any additional signal generator or any other additional hardware. Using the LED lights for signaling immediately draws attention from the following drivers as they are automatically detected.
