Description

[0001] A SYSTEM AND METHOD FOR NEED BASED SPEED LIMITER

[0002] FIELD

[0003] The present invention pertains to speed control of automotive vehicles (autonomous or otherwise), and in particular, controlling and limiting vehicle speed based on needs of different locations and traffic situation.

[0004] DEFINITIONS

[0005] As used in the present disclosure, the following terms are generally intended to have the meaning as set forth below, except to the extent that the context in which they are used indicates otherwise.

[0006] Traffic Speed Management Rules: The term “traffic speed management rules” means rules defined by government authorities to manage the traffic of the vehicles in a city e.g. it includes, but not limited to, speed range from one traffic junction to the next, speed range from one traffic junction to the next for different type of vehicles, speed range for different traffic lanes, aerial routes etc.

[0007] User - User is an individual using public roads / routes through vehicle, it includes a traffic personnel appointed by government authorities to manage traffic situation of the city and at times carrying at least one one-to-one associated User device having the application stored therein with different type of accesses / rights as the role of the user demands.

[0008] Centralized Traffic Controller- The term “Centralized Traffic Controller” hereinafter refers to anyone who has been authorized by government authorities to define and implement the traffic speed management rules in the system.

[0009] Green Corridor / route: The term “green corridor / route” hereinafter refers a route which is created specifically by traffic management authorities, on real time need basis, providing free flow of the movement of vehicles i.e. on these routes stop traffic signal is not there or are minimal to ensure vehicles in emergency reach their destination faster.

[0010] User Device: This is any electronic device that has communication capabilities (e.g. through geo-positioning system). It is selected from the group, but not limited to a smart phone mobile, satellite phone, smart watch, a tablet, a laptop, a palmtop, a computing device, and a portable electronic device which can identify its location / position and having an application stored therein.

[0011] Centralized traffic controller user device: This is any electronic device that has communication capabilities (e.g. through geo-positioning system). It is selected from the group, but not limited to a smart phone mobile, satellite phone, smart watch, a tablet, a laptop, a palmtop, a computing device, and a portable electronic device.

[0012] Terminal cum speed limiter device: This is any electronic device that has communication capabilities (e.g. through geo-positioning system). It is selected from the group, but not limited to a smart phone mobile, satellite phone, smart watch, a tablet, a laptop, a palmtop, a computing device, and a portable electronic device which can identify its location / position including when it is in a geofence or near to a RFID system, NFC compatible devices and communicate with the connected device through wireless technologies e.g. through Bluetooth, WiFi etc. or wired connection. A terminal cum speed limiter device may or may not be having application stored therein. Terminal cum speed limiter device is configured to Vehicle speed system.

[0013] Vehicle Speed System: It means a system in a vehicle computer system including but not limited to engine computer system which controls the vehicle speed and communicates to various components of a vehicle (autonomous or non- autonomous and whether Non-Electric Vehicle, Electric vehicles etc.) which generate / regulate / control speed of the vehicle. BACKGROUND

[0014] Conventional vehicle speed limiters configured to vehicles limit the maximum speed level, as approved by local traffic speed management rules and, beyond which a vehicle cannot achieve speed. In general, conventional speed limiter systems are connected with ECU (Engine Control Unit) or other speed generating modules like in Electric Vehicles electric motorized drive etc.

[0015] The existing speed limiters are ensuring a maximum speed limit up to which a vehicle can get the speed, e.g. commercial vehicles used in mining / construction activities with speed limiter devices can get a maximum speed say upto 50km / hour. In absence of such speed limiter devices in commercial vehicles, used in mining / construction activity, which carry heavy load, in case of an unfortunate accident involving such vehicles with high speed, the impact is very severe and fatal in many cases. Similarly, commercial vehicles carrying passengers need to be careful as over speeding would result in heavy damage of property and lives.

[0016] The existing speed limiters do not address the issue of need of different speed limit at various different location and time e.g. a commercial vehicle carrying passengers and passing through a busy street during busy hours still can drive at maximum speed as per speed limiter even though the objective is to use the maximum speed at state / national highway or express way corridor and at busy routes within city actual vehicle speed should be lesser than what is approved for highways.

[0017] Similarly, in continuation to above example, same commercial vehicle carrying passengers should be allowed to run at higher speed when it’s a public holiday / late night hour when the traffic is not in above referred busy street or when a green corridor is created for emergency vehicles.

[0018] Similarly, personal passenger vehicles are required to follow speed limits of different zones, say near to a busy street or school, speed limit is 40 km / hour and on highway say vehicle is allowed to use a speed up to 120 km / hour, current speed limiter devices are not able to control the speed the vehicle at different locations. Therefore, there is felt a need to provide a system that alleviates the aforementioned drawbacks.

[0019] OBJECTS

[0020] Some of the objects of the present disclosure are described herein below:

[0021] An object of the present disclosure is to provide a system and method for need based speed limiter for automotive vehicles.

[0022] Another object of the present disclosure is to provide a system whereby different speed limits can be applied in the vehicle once a vehicle reaches a defined patch / location coordinates of a road based on traffic speed management rules imposed by government authorities.

[0023] Another object of the present disclosure is to provide a system whereby even more stringent speed limits can be applied in the vehicle once a vehicle reaches a defined patch / location coordinates of a road based on traffic speed management rules imposed by government authorities (e.g. parents may define stringer speed limits for the vehicle if their younger ones are going through a defined route for their safety).

[0024] Another object of the present disclosure is to provide a system whereby when a vehicle is found in an area where the vehicle speed is to be reduced as per traffic management rules at that time raising an alarm / signal to keep driver of the vehicle alert about the speed range of their vehicle at that time duration.

[0025] Another object of the present disclosure is to provide a system whereby a vehicle is forced to be at near stop speed by the user device with admin rights or centralized controller device if the vehicle or its passengers are found to be involved in an offence / crime.

[0026] Another object of the present disclosure is to provide a system whereby a vehicle is forced to be at near stop speed by the user device with admin rights or centralized controller device if the vehicle or its passengers are found going in opposite direction of permissible traffic flow direction allowed in a traffic lane on real time basis.

[0112] FIG.3D explains a scenario wherein a road stretch with 3 speed lanes. Permissible flow of traffic is West to East. Geofences implemented to speed limit for different type of vehicles and lane to be used by different vehicles is as under.

[0113] Speed limit applied for geofence:

[0114] Lane A is occupied wrongly by a Truck at speed of 70 km / hour, during & after entering into Geofence 1 , it will start getting an alarm and speed restriction will be implemented with speed limit of 50 km / hour and during & after passing geofence 3 though speed limit will be changed to 60 km / hour, alarm of wrong lane will continue to and as per rules saved in repository , speed limit can be forced to lower levels.

[0115] Further, Lane B occupied by a Car at speed of 80 km / hour, during & after geofence 1 will get speed restriction of 50 km / hour and during & after geofence 2, speed restriction of 60 km / hour and during & after geofence 3 speed restriction of 90 km / hour.

[0116] Further, Lane B occupied by a Bus at speed of 100 km / hour , during & after geofence 1 will get speed restriction of 50 km / hour and during & after geofence 2, speed restriction of 40 km / hour and during & after geofence 3 speed restriction of 80 km / hour.

[0117] FIG.3E explains a scenario wherein a road stretch with 3 speed lanes. Permissible flow of traffic is West to East. Geofences implemented to speed limit for different type of vehicles and lane to be used by different vehicles is as under.

[0118] Speed limit applied for geofence:

[0119] Here, a Car is moving in wrong direction i.e. east to west at a speed of 20 km / hour. During & after crossing the geofence 3, it gets a notification through alarm about wrong direction movement and speed limiter activates and bring down the speed of car to near stop level to force driver of car to correct the direction. FIG. 4 explains the Vehicle Speed System (600), which includes ECM (Engine Control Module). Herein, ECM gets feedback from various sensors and through the processor it communicates various instructions to parts / components of vehicle.

[0120] The terminal cum speed limiter device (400) is configured to Vehicle Speed System (600) and in turn to ECM to read the readings of various sensors along with notifications from server (500) and thereby implement speed limit rules for respective lanes and vehicles moving in wrong lane / direction.

[0121] In an embodiment, rules saved in repository (502), can put speed limit only during the presence of terminal cum speed limiter device (540) in the geofence.

[0122] TECHNICAL ADVANCEMENTS AND ECONOMICAL SIGNIFICANCE

[0123] The present disclosure described herein above has several technical advantages including, but not limited to, the realization of system for need based speed limiter of vehicles, which:

[0124] • Address the technical issue of speed limiting of vehicles at defined road stretches as per traffic management rules.

[0125] • Addressing the technical issue involved in implementing near stop speed of vehicle / drivers involved in traffic rules violation or other unlawful activities.

[0126] • Implementing stringent speed limits for new drivers or young learners for defined road stretches to ensure they do not end up in accidents.

[0127] • Minimizing accidents and resulting damages due to speed violation by drivers.

[0128] • Implementing speed limit rules based on real time traffic congestion and thereby allowing time to traffic personnel to clear the traffic jam as limited number of vehicles would be allowed (due to slow speed) to keep coming in that direction. • Sending display message and / or voice message, through connected audio / video system of the vehicle, about speed limits once a vehicle is passing through a geofence created by system to keep awake and alert the drivers.

[0129] • Surprize element to drivers as geofence for speed limit can be created anywhere and anytime, ensuring the drivers are alert and law abiding, minimizing sever accidents, fatalities, and insurance costs.

[0130] • Different speed range limits can be implemented for different category of vehicles through the terminal and speed limiter device programming e.g., a geofence sending a signal to passing vehicle to maintain speed limit upto 60 km / hour will be implemented by a car speed control system as 60 km / hour and a heavy dumper will implement as 20% less (if programmed that way) from the geofence limit.

[0131] • During the heavy fog, heavy rains or low visibility situations, current invention can help to control the speed limits at designated patches / stretches of road and help in minimizing accidents.
