USING ISA SYSTEM TO DECELERATE TRUCK UPON ENTERING GEOFENCED AREA
A method of decelerating a vehicle upon entering a halt zone includes determining a location of a vehicle at routine intervals while the vehicle is traveling along a road; determining when the vehicle enters a halt zone; and upon determining that the vehicle has entered a halt zone, limiting a speed of the vehicle to a nominal speed. The method preferably is performed by an intelligent speed adaptor (ISA) system of a vehicle. The vehicle preferably is part of a fleet of commercial vehicles, and a fleet manager preferably is notified when a vehicle has entered a halt zone.

25 . A method, performed by an intelligent speed adaptor (ISA) system of a vehicle, of decelerating the vehicle upon entering a halt zone, comprising determining a location of a vehicle at routine intervals while the vehicle is traveling along a road, determining when the vehicle enters a halt zone, and upon determining that the vehicle has entered a halt zone, limiting a speed of the vehicle to a nominal speed, wherein the halt zone comprises a geofenced area defined by GPS coordinates, wherein the location of the vehicle is determined based on GPS coordinates of the vehicle, and wherein the vehicle is determined to enter a halt zone when the GPS coordinates of the vehicle are within the geofenced area.

28 . The method of claim 25 , wherein the method is performed for a plurality of different halt zones.
29 . The method of claim 25 , wherein a halt zone comprises an area of a road leading up to an overpass which the vehicle is unable to traverse, whereby damage or injury from a collision of the vehicle with the overpass may be prevented.
30 . The method of claim 25 , wherein a halt zone comprises an area of a road leading up to a tunnel such that the ISA system will cause the vehicle to halt upon entering the halt zone prior to reaching an entrance of the tunnel.
31 . The method of claim 25 , wherein the halt zone comprises an area comprising a vehicular path located adjacent a government building.
32 . The method of claim 25 , wherein the halt zone comprises an area of an airport.
33 . The method of claim 25 , wherein the halt zone comprises an area of a military base.
34 . The method of claim 25 , wherein the ISA limits the speed of the vehicle to a nominal speed by disengaging the accelerator of the vehicle.
35 . The method of claim 25 , wherein the nominal speed is 1 kilometer per hour.
36 . The method of claim 25 , wherein the nominal speed is 1 mile per hour.
37 . The method of claim 25 , wherein the nominal speed is 5 miles per hour or less.
38 . The method of claim 25 , wherein the ISA limits the speed of the vehicle to a nominal speed by preventing signals indicating an acceleration from being sent to a main control module comprising an engine control unit of the vehicle.
39 . The method of claim 25 , wherein the ISA limits the speed of the vehicle to a nominal speed by preventing signals sent in response to depression of an acceleration pedal from being received by an engine control unit of the vehicle.
40 . The method of claim 25 , wherein the ISA limits the speed of the vehicle to a nominal speed by modifying signals that are sent in response to depression of an acceleration pedal to an engine control unit of the vehicle.
41 . The method of claim 25 , wherein the ISA limits the speed of the vehicle to a nominal speed by preventing signals sent by a throttle position sensor from being received by an engine control unit of the vehicle.
42 . The method of claim 25 , wherein the ISA limits the speed of the vehicle to a nominal speed by modifying signals sent by a throttle position sensor to an engine control unit of the vehicle.
43 . The method of claim 25 , wherein the ISA limits the speed of the vehicle to a nominal speed by signaling an engine control module of the vehicle that the accelerator is not depressed.
44 . The method of claim 25 , further comprising actuating brakes of the vehicle for active braking of the vehicle after entering the halt zone.
45 . The method of claim 25 , further comprising sending a notification that the vehicle has entered the halt zone upon determining that the vehicle has entered the halt zone.
46 . The method of claim 45 , wherein the notification comprises a text message or an email.
