APPLICANT’S PATENT AGENT , Description:FIELD OF INVENTION

The present invention relates to passenger cabin control systems for automotive applications. In particular, the present invention relates to a system for leveraging data to detect any emergency situations in automobiles. The present invention also relates to the method for leveraging data to detect any emergency situations for opening the windows by using the system configured according to the present invention.

BACKGROUND OF THE INVENTION

An important criterion to be considered in automobile designing is quickest evacuation of vehicle occupants through the windows, in case of emergency situations, such as crash or fire etc.

Rollover is a type of vehicle crash in which a vehicle tips over onto its side or roof. Rollovers have a higher fatality rate than other types of vehicle collisions.

Crash is a situation of violent collision of an automobile with an obstacle or another vehicle.

Vehicle fire often occurs due to a combination of causes, e.g. human factors, mechanical, electrical and chemical factors.

Therefore, an emergency escape mechanism is a necessity in case of any such vehicle accident or crash.

DISADVANTAGES WITH THE PRIOR ART

At present, detecting emergency situations such as vehicle rollover or collision or fire is made possible only by means of independently operating dedicated individual systems therefor. The window and door opening mechanisms are also available, but it is not possible to intimate the user about the vehicle safety mechanism in case of such serious emergency situations.
DESCRIPTION OF THE PRESENT INVENTION

The present invention relates to passenger cabin control systems for automotive applications, particularly a system for leveraging data to detect any emergency situation using the real time data obtained from onboard accelerometers in automobiles, more particularly a window opening mechanism on detecting an emergency situation inside the vehicle cabin operated by such system.

The present invention also relates to a method for leveraging data to detect any emergency situations by obtaining real time data from onboard accelerometers by using the system configured according to the present invention.

The vehicle safety can be substantially improved for vehicle occupants by providing an emergency escape mechanism after the crash or fire. Accordingly, when the parameters exceed the respective predetermined threshold values, a safety issue for the vehicle occupants is detected by such mechanism and the door or power window opening mechanism is immediately initiated as the emergency escape mechanism for their timely evacuation.

Therefore, the present invention generally relates to passenger cabin control systems for vehicle applications. In particular, the invention relates to a system for leveraging vehicle data to detect any roll-over by obtaining real time data from the onboard accelerometers to allow opening of the doors and/or windows after the rollover to avoid any further serious injuries to the passengers. The present invention ensures opening of doors/windows in case of roll-over, so that the vehicle occupants could be rescued in time. The passenger cabin control system continuously monitors and compares the real-time accelerometer data input with the stored acceleration data required for initiating a rollover mapped onto the system.

The possibility of such a vehicle rollover can be predicted based on a fairly simple model explained in details in the following:
The key parameters of the vehicle to be considered include:

• Center of gravity, located at approximately one-third of the total height of the vehicle.

• Track width of the vehicle.

• Distance between two wheels diagonally across from each other.

With these key parameters, the lateral acceleration required to initiate a rollover for a particular vehicle can be calculated easily.

For all axis rollover conditions, the accelerations in x, y, z axes are computed and the corresponding tan inverse angles are obtained to detect the rollover. The rollover is detected, when the angles exceed the minimum angle for rollover. The time for corresponding angular changes is also calculated based on acceleration data and change in angle data for considering whether the vehicle has not actually come back to normal condition. Whenever, the existing model and the accelerometer data matches each other, the rollover is detected and this actuates the power window regulator for opening the window for evacuating the occupants to escape the vehicle without any further injury. The speed-controlled power windows also ensure that the time of rollover also affects the power window opening.

In particular, the present invention also relates to a system for leveraging vehicle data to detect any crash to facilitate the opening of the windows or doors after the collision for avoiding any further serious injuries to the vehicle occupants.

The crash detection is done by onboard accelerometers. When the vehicle input through accelerometers exceeds the threshold value for collision data, the crash is detected and the windows or doors open completely to ensure that the vehicle occupants can safely escape from the vehicle without any further injuries.
A collision sensing system for a power window system includes at least one door opening state detector and power window actuation inhibiter each. The power window is actuated, when the collision detector detects a vehicle collision. The power window opening actuation inhibits the opening of the power window, when the door opening state detector detects the open state of the side doors. If the door is already open after the collision, the power window mechanism doesn’t operate. Thus, the escape mechanism ensures opening of the windows or doors.

The present invention offers a mechanism to collect the inputs of vehicle interior conditions through camera input and sensor data to facilitate the opening of the vehicle doors and also to intimate the vehicle user/s about the actual situation to take necessary remedial action.

The onboard temperature sensors measure the temperature inside the cabin, so that in case of a fire scenario inside the vehicle cabin, the windows open for facilitating the escape of the vehicle occupants.

A smoke sensor present in the cabin detects the smoke levels going beyond the predetermined threshold level. Smoke may arise due to fire in vehicle cabin or due to fire in the engine cabin, which enters the vehicle cabin.

To prevent any safety issues of the vehicle occupants inside the vehicle cabin, the doors and windows should be open in case of a fire by sensing smoke and temperature inside the vehicle cabin.

A camera is deployed inside the cabin to capture the image and compare it with pre-stored image to confirm whether there is any fire situation prevailing inside the vehicle cabin.

Whenever, there is fire inside the vehicle cabin, the door opening sequence is actuated with the help of the GSM device provided in the vehicle by sending a SMS to the vehicle owner for giving intimation about the presence of fire in the vehicle cabin.

An object of the present invention is to provide a system for data communication to detect any emergency situation in automobiles.

Another object of the present invention is to provide a system for data communication to open the windows or doors of a vehicle in case of detecting a roll-over state.

DETAILED DESCRIPTION OF THE ACCOMPANYING DRAWINGS

In the following, different embodiments of the present invention will be described in more details with reference to the accompanying drawings without limiting the scope and ambit of the present invention in any way.

Figure 1 shows the flow-diagram of a first embodiment 100 of the vehicle control system configured in accordance with the present invention for leveraging real-time vehicle data for opening power windows of the vehicle on detecting a vehicle roll-over situation. The standard vehicle parameters are stored as vehicle data 100 in the control system. The vehicle control system 100 is configured as a control system for leveraging vehicle data storage 110 (threshold values) stored in the control system 100 for detecting any existing roll-over situation. The key vehicle characteristics being the center of gravity located at about one-third of the total height of the vehicle, and its track width, i.e. the distance between two wheels diagonally across from each other. This is executed by obtaining real time input data of the roll angle in all axes obtained from the onboard accelerometers in a sub-system 120.

Equipped with this information, the lateral acceleration required to initiate a rollover for a particular vehicle can be calculated quite easily in the microprocessor 130. Now, the acceleration in x, y, z axes are computed for all axes rollover conditions and the corresponding tan-1 angles are found for detecting the actual rollover situation in the comparator 140. If the angles exceed the stored minimum angle for rollover, the system determines that roll over is present. Further, the time for corresponding angular changes is also calculated using the time-matrix 150, based on acceleration data and change in angle data, to consider whether the vehicle has actually come back to its normal condition. If the existing model and accelerometer data matches each other, the system detects the presence of a rollover at gate 160, it actuates the power window regulator 170 for opening the windows for the occupants to escape the rolled over vehicle without any further injury. The speed controlled power windows ensure that time of rollover also affects the power window opening.
Figure 2 shows the flow-diagram of a second embodiment 200 of the vehicle control system configured in accordance with the present invention for leveraging vehicle data from on-board sensors and controllers for opening power windows of the vehicle in case of detecting a vehicle crash situation. The input from proximity distance sensors at 220 provided for measuring the distance between the object and vehicle are compared with the threshold values stored in the vehicle data storage 210. Further, the microprocessor at 230 also computes the vibration data from the accelerometer and compares this data with the comparator 250 for threshold values of collision. The vehicle inputs through sensors 220 are compared in 240. If it exceeds the threshold values, the collision is detected. A collision sensing system 280 for a power window system has a door opening state detector 260, a gate 270, a door actuation inhibitor at 300 and a power window actuation inhibiter 290. The power window and door is actuated when a collision is detected. The power window opening actuation inhibiter 290 inhibits the opening of the power windows and doors 300 when the door opening state detector 260 detects the open state of the side doors. If the door is already opened after the collision, the power window mechanism 290 does not operate. Thus, the escape mechanism is ensured by opening the power windows and doors 290 and 300.

Figure 3 shows the flow-diagram of a communication and actuation mechanism 300 configured in accordance with the present invention for detecting fire situation in the vehicle and communicating the same to the vehicle user or owner for enabling the opening of power windows of the vehicle. As soon as the vehicle is started at 310, the camera 320 detects the presence or absence of the occupant/s inside the vehicle. Simultaneously, at least one fire and smoke situation detecting sensor 330 installed inside the vehicle cabin detects the presence or absence of a fire or smoke in the vehicle. If fire sensor 330 does not detect any smoke, no alert is issued. However, if this sensor 330 also detects fire situation inside the cabin, then another sensor 350 checks the presence of the occupant/s inside the cabin. If both the sensors 330 and 350 determine in affirmative, a high signal is sent to the user to intimate that there is a fire in the vehicle with occupants present who need to be evacuated from the vehicle.
So, the vehicle user/owner is alerted via an SMS alert at 360 to open the power windows at 390 after a predetermined time lag, which is sufficient enough for the vehicle to be stopped, when the vehicle is in motion, even after a predetermined time lag if the vehicle is not stopped due to any circumstances the windows opening mechanism should be available for escape of the occupants.

However, if the sensor at 330 determined in ‘Yes’ and but the sensor at 350 determines in ‘No’, then there are no occupants present, but a fire is detected. Then at step 370, an SMS alert is issued to the vehicle user/owner via SMS, who at step 380 activates the power windows via SMS actuation to open at step 395. However, if the windows do not open even after SMS actuation by the user/owner at step 380, then opening the power windows occurs at step 390 after a predetermined time lag for facilitating the safe escape of the vehicle occupants from the vehicle.

The in motion vehicle will foster opening of windows only not door. So that the smoke from the fire is guided away from the vehicle preventing the harm to passenger. The vehicle motion has to be stopped manually only and not automatically. The fire detection is possible when the driver/owner is present. Moreover, this particular invention pertains mainly when the driver/owner is absent in the vehicle. For example, fire in vehicle when you have parked it in a mall or office parking and you are absent.
