FIELD OF THE INVENTION
The present invention relates to the field of driving assistance system. More particularly, the present invention relates to the field of vehicle overtopping collision avoidance and driving system for obstacles.
BACKGROUND OF THE INVENTION
The technologies in vehicle safety are more advanced and predominantly concentrated on safety of drivers and pedestrians. The safety system ensures the safety of drivers and to avoid collision causing factors. Said systems also applies for heavy motor trucks like concrete transport truck, mobile crane, dump truck, garbage truck, log carrier, refrigerator truck, haul truck and the like. There are several of mirrors and gadgets which provides support for drivers in assisting them during movement in on/off roads.
Even though foresaid features assist drivers, said features are useless and ineffective during passing under an obstacle or preferably a bridge. The height of the container varies depending upon the loads. The driver can predict height of the vehicle if the container is standard but as different types of loads or containers are placed on the truck, the total height of the vehicle is unpredictable. Cities usually have thousands of obstacles such as bridges and tunnels. Most of the bridges and tunnels have head rooms or clearance particularly the inner height of the bridge or tunnel which is shown on the sign board or on the bridge itself.

In another aspect, the inner height may not be displayed on sign boards or
on the obstacles and the driver has to predict the height blindly which may
lead to overtopping and a major road block or even worse collision. The
driver may have to re-route the vehicle and the problem still persists in
another road situation. An external arc is also placed in front of the obstacle
for the driver to identify and predict the clearance height,. but the above
■ method is non effective as the driver has to predict the height blindly.
Uncertainty still persist as the driver cannot guess the actual height of the
vehicle.
In order resolve the above said issue, there are many existing innovations introduced to resolve the above said issue. Said existing inventions may effectively determine and predict the height of the obstacle. The existing inventions proposed to resolve the above said issue are discussed in the prior art sections. Patent application WO2019144750 describes a safety belt light emitting system for vehicle. Said invention comprises safety seat belt assembly with light emitting means for vehicle drivers. Even though the existing invention clearly describes a safety system for drivers, it did not proposes any identification means to prevent overtopping.
United States patent US2019234601 describes a signal lighting device. The invention comprises a vehicle safety lighting which emits high intensity flashing yellow light to lead vehicle to be either braking, slowing or stopping.

The invention may convey a solution to avoid accidents but the invention did not convey any prediction of overtopping during crossing an obstacle.
Indian patent application 201911030146 describes a vehicle accident avoidance system during driving on curved roads. The invention comprises of sensors, LED indicators and an open source micro-controller wherein said sensors detect upcoming vehicles on curved roads. The invention clearly conveys an accident avoidance system during driving conditions, but the existing invention did not convey any height measuring means to identify the overtopping of bridges.
There are no such inventions proposed in the existing systems about identifying the obstacle and predicting the present height of the vehicles. There may be barriers present in front of the bridges but there are no prediction system introduced to differentiate the height difference or free spaces.
Therefore, the present invention introduces a method to predict the overtopping of vehicles particularly trucks whereas said system provides a predicting means to determine the inner height of the obstacle from a vehicle operable distance. Furthermore, the invention also, comprises a cloud storage means wherein the system provides navigational directions to the driver in case of overtopping and suggest nearest alternative direction for the driver.

OBJECTIVE OF THE INVENTION
The main objective of the present invention is to propose a method to predict the overtopping of vehicle when crossing an obstacle.
Another main objective of the present invention is to provide other alternative nearest road ways by navigational means in case of overtopping situation.
Still another objective of the present invention is providing an alert system in case of overtopping.
Yet another objective of the present invention is to alert other drivers with necessary information of the obstacle before passing near to the obstacle
Yet another objective of the present invention is constructing the system in low cost.

Fig 1a and 1b describes the apparatus for overtopping prevention system (1) for vehicles in accordance to the main aspect of the present invention. Fig 1a represents a vehicle (2) travelling across an obstacle (5) separated by a distance (d). The apparatus (1) is disposed on the top portion of the vehicle

(2) preferably facing on the front side of the vehicle cabin (8).The total height (a1) is distance between the top portion of the vehicle (2) to the ground level. The inner height of the obstacle (5) is the distance between the inner top surface and the ground level of the obstacle (5) which is taken as obstacle height (hi). The apparatus (1) comprises of a height monitoring device (11), an alarming means (21) and GPS database (31) wherein said device (11) is wirelessly connected to the GPS database (31). Said obstacle is a man-made construction preferably a bridge or tunnel. Referring more specific with Fig 1a, the apparatus (1) processes and calculates the obstacle height (hi) by considering the distance (d) and compares the resultant value to the total height (a1) of the vehicle. The system predicts the overtopping height by comparing the obstacle height (hi) and total height (a1).
With reference to Fig - 1b, the diagram represents a particular portion of the city with road networks, plurality of vehicle (2, 3, 4) and plurality of obstacle (5, 6, 7). The plurality of vehicle (2, 3, 4) are disposed on different parts of the road networks and obstacles are disposed on the corresponding road networks. If one of the obstacle (5) which has an obstacle height (hi) is predicted to be lower the total height (a1) of the vehicle (2), then the apparatus (1) sends relevant height data to the GPS database (31) so that other vehicles (3, 4) with the installed apparatus (1) can provide alternative directions to the respective drivers if the obstacle (5) is found below the height criteria.

The processor (16) triggers said alarming means (21) in case of height hindrance and the collected data is transferred to the GPS database (31) through wireless communication means (17).

Fig 3 describes the flowchart process representation of overtopping prevention method in accordance to the present invention. Initially, the height sensing means (12) measures the total height (a1) of the vehicle (2) and transfers the collected data to the processor (16). If the vehicle (2) encounters an obstacle, the distance sensing means (13) measures the distance (d) between the vehicle (2) and the obstacle (5). The collected data is transferred to the processor (16). The image capturing means (14) captures the picture of the upcoming obstacle (5) simultaneously when the distance (d) is measured. The picture is processed by the image processing module (161) and obstacle height (hi) is predicted by processing the distance (d) with the captured image.
Referring more specific, the processor (16) compares the value of total height (a1) with the obstacle height (hi). If the total height (a1) is found to be lesser than the obstacle height (hi) (i,e a1 < hi), then the apparatus (1) continues to monitor for upcoming obstacles. If the total height (a1) is found to be greater than the obstacle height (hi) (i.e. a1 > hi ), then the processor (16) alerts the driver of the vehicle (2) through said alarming means (21). The collected data including the location from the GPS module (15)are sent to the GPS database (31) by the processor (16) through wireless communication means (17). Said apparatus (1) also suggests another alternative road way to the driver of other vehicles respective to vehicle height. The directional guidance is sent to the display unit (23) of other plurality of vehicles through wireless communication means (17).

The present invention is tested in a real-time application where said apparatus (1) is installed in a truck. It is found that the apparatus identified and predicted the overtopping height effectively. The apparatus (1) calculated the total height (a1) of the vehicle and estimate the distance (d) effectively, the driver of the vehicle was alerted by alarming means and alternative directions are suggested for the driver. The system was cost efficient to install on the vehicle and more efficient than conventional systems. Therefore, the present invention is more advantageous than -conventional methodologies.
