Abstract
A 360 safety system for automated verification of a 360 walk-around prior to vehicle engagement is described. The 360 safety system includes at least three sensors that receive a signal from a transmission fob, where one signal may be received by one of the at least three sensors at a time. The signals received by the at least three sensors are configured to be signal inputs to an operating system, where the operating system is in electrical communication with the at least three sensors. Each signal input received by one of the at least three sensors is processed by the operating system to generate a verification output displayed on a HMI of the operating system. When the CPU determines a valid signal input of each of the at least three sensors has been stored, the operating system processes the signal inputs and generates outputs that permit engagement of the vehicle.
Description
BACKGROUND

Heavy machinery and motorized vehicles associated for use in a regulated environment (e.g. Occupational Safety and Health Administration regulations) are commonly the source of injury in the workplace and damage to property. These injuries may arise from improper, incomplete, or failed inspection of the heavy machinery or motorized vehicle (i.e. vehicle) prior to the operation of the vehicle. For example, if a driver of a vehicle fails to inspect vehicle tires, the conditions of the rear of the vehicle, including obstructions, peoples, proper attachment of towing apparatus, or visible issues to the vehicle, prior to operation of the vehicle, damage to property or persons may occur.


In order to reduce injuries and property damage associated with vehicles, federal and state regulations, as well as company safety policies and procedures, require drivers to inspect the vehicle and its accompanying surroundings in a 360 degree manner prior to driving the vehicle (i.e. 360 walk-around). A 360 walk-around includes the driver inspecting the vehicle and the immediate surrounding for any hazards by walking completely around the vehicle. The 360 walk-around allows a driver to identify hazards that would not be visible from the mirror views of the driver's seat of the vehicle or the camera views provided by a back-up camera or a series of cameras around the vehicle.


While inspection of a vehicle and its surroundings prior to operation is typically mandated either by law or company policy, conventional methods for inspection are deficient. Conventional methods for inspection include a driver performing the 360 walk-around of the vehicle and manually verifying the 360 walk-around, such as through pen and paper or a mobile computer device. This manual inspection and entry of verification provides ample opportunity for the 360 walk-around to be improper, incomplete, or not done at all, as the driver may verify inspection without actually performing the 360 walk-around.


It is therefore desirable to have a 360 safety system that does not provide manual verification of a 360 walk-around, and rather the 360 walk-around is verified in an automated manner with minimal opportunity for manual override. It is further desirable that the 360 safety system prohibit ignition, shifting, and/or full functionality of the vehicle prior to automated verification of the 360 walk-around.

DETAILED DESCRIPTION

A 360 safety system for automated verification of a 360 walk-around prior to vehicle engagement (e.g. ignition or gear shifting) to ensure the vehicle and surrounding are safe for the vehicle to be moved is described. The 360 safety system includes at least three sensors that receive a signal from a transmission fob, where one signal may be received by one of the at least three sensors at a time. The signals received by the at least three sensors are configured to be signal inputs to an operating system, where the operating system is in electrical communication with the at least three sensors. Each signal input received by one of the at least three sensors is processed by the operating system and may generate a verification output displayed on a HMI of the operating system. When each of the at least three sensors has received a signal from a transmission fob, the operating system processes the signal inputs and generates outputs that permit engagement of the vehicle.



FIG. 1 represents a 360 safety system 100 for automated verification of a 360 walk-around prior to vehicle engagement. The 360 safety system 100 includes at least three sensors 102, a transmission fob 120, and an operating system 200. The at least three sensors are placed on a vehicle 500, such as heavy machinery (i.e. machinery that may be motorized or non-motorized) or motorized vehicles both used in connection with federal or state regulated activities and/or subject to safety policies or procedures imposed by the owner of the vehicle 500 (i.e. a regulated vehicle).


The at least three sensors 102 are removably attached to the vehicle 500 and are in electrical communication with the operating system 200. The at least three sensors 102 may be in hardwire or wireless electrical communication with the CPU 204. When the at least three sensors 102 are in hardwire electrical communication with the CPU 204 it may be via a communication wire of communication lights (i.e. turn signal or hazard lights) of the vehicle 500. The at least three sensors 102 are in hardwire electrical communication with a component of the vehicle to supply power, such as the headlights. The at least three sensors 102 are in hardwire electrical communication with the vehicle frame to ground the at least three sensors 102. The at least three sensors 102 have a zone of detection 300 (see FIGS. 3a-3e), a receiver 105 (see FIGS. 2a, 2b, and 2g-2i), and a bracket 104 (see FIGS. 2a-2d, and 2g-2j). The at least three sensors 102 may include an adhesion brim 106, a light emitting diode (LED) 107, and a sensor CPU 114 (see FIGS. 2a, 2b, and 2g-2i).


The receiver 105 of the at least three sensors 102 receives the signal from the transmission fob 120. The receiver 105 may be an infrared optic receiver or sonic receiver that corresponds to the signal (e.g. wavelength) transmitted by the transmission fob 120. The receiver 105 may have a transmission depth 108 from 3.05 meters (10 feet) or less. The transmission depth 108 is the maximum distance measured from the receiver 105 to the transmission fob 120, wherein the receiver 105 may receive the signal when transmitted by the transmission fob 120.


The transmission fob 120 of the 360 safety system 100 transmits a signal to be received by one of the at least three sensors 102. The transmission fob 120 may be an infrared transmitter or sonic transmitter that produces the signal corresponding to the receiver 105 of the at least three sensors 102. The transmission fob 120 may be of a size that is handheld. For example, in order for the transmission fob 120 to send the signal with successful receipt by the receiver 105 of one of the at least three sensors 102, the transmission fob 120 must be within one of two angles 302, the transmission depth 108, and a transmission circumference 122, where together these boundaries define the zone of detection 300 (as shown in FIG. 3a).



FIG. 2a and FIG. 2d represents a top view of one of the at least three sensors 102. FIG. 2b, FIGS. 2e, and 2i represents a side view of one of the at least three sensors 102. FIG. 2c, FIG. 2f, and FIG. 2g represent a front view of one of the at least three sensors. FIG. 2h represents an exploded perspective view of one of the at least three sensors 102. FIG. 2j represents a perspective view of one of the at least three sensors 102. The bracket 104 of the at least three sensors 102 includes a bracket opening 109 and a bracket depth 110. The bracket 104 partially surrounds and houses the receiver 105 distal to and centered within the bracket opening 109.


The receiver 105 is housed in the bracket 104 such that it is substantially perpendicular to the vehicle 500 when one of the at least three sensors 102 is removably attached to the vehicle 500 when the adhesion brim 106 is a fixed brim (see FIGS. 2a-2f). The receiver 105 is housed in the bracket 104 such that it may be from plus or minus 55 degrees from perpendicular (i.e. along the y-axis) to the vehicle 500 when the adhesion brim 106 is a pivot brim (see FIGS. 2g-2j). Further, the receiver may be rotated 360 degrees (along the x-axis) when the adhesion brim 106 is a pivot brim). The bracket may further house the LED 107 visible through an LED opening 123, where the LED opening 123 is of a shape and size that permits the LED 107 to be visible through the opening. The bracket may be of any non-reflective material such as plastic, metal, or rubber. The bracket opening 109 is from 2 to 9 millimeters. The bracket depth 110 is from 4 to 14 millimeters.


The adhesion brim 106 of the at least three sensors 102 removably attaches the at least three sensors 102 to the vehicle 500. The adhesion brim 106 may be a fixed brim where the receiver remains in a fixed substantially perpendicular position relative to the vehicle 500 (see FIGS. 2a-2f). The adhesion brim 106 may be a pivot brim where the receiver may be pivoted from plus or minus 55 degrees from perpendicular to the vehicle 500 (see FIG. 2g-2j). The adhesion brim may be formed as a part of the bracket 104, such as when the adhesion brim 106 is a fixed brim.


Further, the adhesion brim may be a means for removably attaching the at least three sensors 102 to the vehicle to allow pivoting of the receiver 105 from plus or minus 55 degrees from perpendicular to the vehicle 500. For example, as shown in FIGS. 2g-2j, the means for removably attaching the at least three sensors includes a screw attachment of the bracket 104 to a pivot 116, and screw attachment of the pivot 116 to a plate 118, where the bracket 104 pivots from each of two pivot points 117 of the adhesion brim 106 around the y-axis. Further, the pivot 116 may be in screw attached to the plate 118 at the x-axis pivot point 137. The screw attachment of the bracket 104 to the pivot 116 at the pivot points 117 allows for rotational movement (e.g. pivoting) of the bracket around the y-axis, where the receiver may be positioned from plus or minus 55 degrees from perpendicular to the vehicle 500. The screw attachment of the pivot 116 to the plate 118 at the x-axis pivot point 137 allows for rotational movement of the bracket around the x-axis, where the receiver 105 may be positioned at any of 360 degrees around the x-axis in relation to the vehicle 500 (see FIG. 3h). The screw attachment of the bracket 104 to the pivot 116 at the pivot points 117 provides that rotational movement of the bracket 104 does not occur when the vehicle 500 is under movement.


The adhesion brim 106 may be removably attached to the at least three sensors 102 to the vehicle 500, such as through adhesive, screws, or bolts. FIGS. 2a, 2b, and 2c represents an adhesive adhesion brim 106 that is a fixed brim, where the adhesive adhesion brim 106 is adjacent to and surrounds the bracket opening 109. The adhesive adhesion brim 106 receives adhesive for removable attachment to the vehicle 500. FIGS. 2d, 2e, and 2f represent a screw and bolt adhesion brim 106 that is a fixed brim, where the adhesion brim 106 extends upward from the bracket opening 109 forming an up-side-down “L” shape (see FIG. 2e). The screw and bolt adhesion brim has one or more adhesion brim holes 115 to receive the screws or bolts for removable attachment of one of the at least three sensors 102 to the vehicle 500.


The LED 107 provides an indication that the signal has been received by the receiver 105 via illumination. The LED 107 is housed by the bracket 104 distal to the LED opening 123. The LED 107 may be in electrical communication with the operating system 200, such as via the sensor CPU 114.


Each of the at least three sensor CPUs (central processing unit) 114 are configured for receiving outputs from and transmitting inputs to the CPU 204 of the operating system 200 via the computer readable non-transient software code and data stored in the storage medium 504. The sensor CPU 114 is further configured for transmitting outputs to the LED 107 and receiving inputs from the receiver 105 and transmitting outputs to the CPU 204. For example, each of the at least three sensor CPUs 114 may transmit (as an output from the sensor CPU 114) the signal inputs to the CPU 204 and receive (as an input to the sensor CPU 114) activation outputs from CPU 204 configured for LED activation of the LED 107 and receiver 105, and receive (as an input to the sensor CPU 114) sensor deactivation outputs from the CPU 204 configured for deactivation of the LED 107 and receiver 105. The sensor CPU 114 includes a sensor processor 702 and a sensor storage medium 704, where the sensor processor 702 and the sensor storage medium 704 are communicatively coupled.


The sensor storage medium 704 may be an electrically erasable programmable read-only memory (EEPROM), a magnetic, optical, or semi-conductor memory, another storage device, or the like. The sensor storage medium 704 may be a fixed memory device, a removable memory device, such as a memory card, remotely accessed, or the like.



FIGS. 3a-3h represent the zone of detection 300 of the at least three sensors 102 from various views. The zone of detection 300 (in connection with the placement on the vehicle 500) of the at least three sensors 102 does not permit more than one of the at least three sensors 102 to receive a signal from a transmission fob 120 at a time (i.e. one signal is received by only one of the at least three sensors 102). The zone of detection 300 (designated by the diagonal lines in FIGS. 3a, 3e, and 3f) includes two angles 302, where the zone of detection extends outward in a conical manner, although this is represented in two dimensions in a triangular manner in FIGS. 3a, 3e, and 3f. The zone of detection is formed by the two angles 302 and the transmission depth 108. At the maximum for the transmission depth 108, an outer edge of the zone of detection is defined by a transmission circumference 122, which is the circumference of the conical zone at the maximum transmission depth 108.


The two angles 302 may be from 16.7 degrees as measured from a centerline 301 (the centerline is a reference line extending out from a center of the receiver 105 perpendicular to a wall of the bracket 104 distal to a bracket opening 109) or less. Preferably, the two angles 302 on each of the at least three sensors are equal. The zone of detection 300 may have two different angles 302 for each of the at least three sensors 102, depending on the placement of the at least three sensors 102 on the vehicle 500 in order to maintain receipt of a signal by only one of the at least three sensors 102 at a time.


The zone of detection 300 may be modified depending on the bracket depth 110 and the bracket opening 109 of the at least three sensors 102, provided that the two angles 302 remains from 16.7 degrees or less. The two angles 302 of zone of detection 300 are directly proportional to the bracket depth 110 and the bracket opening 109. For example, when the bracket depth 110 is 8.7 millimeters, the bracket opening 109 is 5.22 millimeters, and the transmission depth 108 is 3.05 meters (10 feet), the zone of detection 300 provides a 1.83 meter (6 feet) diameter of the transmission circumference 122 (as indicated by “d” in FIG. 3.) at the transmission depth 108 for the zone of detection 300 providing a triangular area of 2.79 square meters and a transmission circumference 122 of 5.74 meters (18.84 feet). With this zone of detection 300 having the transmission circumference 122 of 5.74 meters (18.84 feet) for detection at the transmission depth 108, each one of the at least three sensors 102, must be placed at least 1.83 meters apart, as measured from parallel centerlines 301.


The zone of detection 300 may further be modified depending on the transmission depth 108. The triangular area of the zone of detection 300 is directly proportional to the transmission depth 108. The transmission depth 108 may be modified by the type of receiver 104 in each of the at least three sensors 102, where the receiver permits a maximum transmission depth 108 from 10 feet of less.



FIGS. 3b-3d represent the zone of detection 300 from a top, side, and rear view, respectively to show the zone of detection 300 in a conical manner. The transmission circumference 122 is the circumference of the conical area in which the receiver 105 may receive a transmission from the transmission fob 120 at the transmission depth 108 and is from 5.74 meters (18.84 feet) meters or less. The transmission circumference 122 may be modified by modifying the transmission depth 108 and/or the angle of the receiver 105 in relation to the vehicle 500. For example, it may be advantageous to modify the transmission circumference 122 to encourage a user of the 360 safety system to be in a certain position (i.e. kneeling) to successfully transmit a signal to the receiver for proper inspection of a portion of the vehicle 500 (for example, see the transmission circumferences in FIGS. 4c-4f). FIG. 3g. represents how the zone of detection 300 is modified as the sensor 102 pivots on an adhesion brim 106 that is a pivot brim.



FIGS. 4a and 4b represent the placement of the at least three sensors 102 on the vehicle 500. The placement of the at least three sensors 102 provides that the shortest distance to transmit a signal to each of the at least three sensors 102 and to arrive back at the driver's seat, is to take a 360 degree path around the vehicle 500. The placement of the at least three sensors 102 in connection with the zone of detection 300, transmission depth 108, and angle of the receiver 105 in relation to the vehicle 500 further provides that the signal is only received by one of the at least three sensors 102 at a time.


For example, the notation of “a” at each of the least three sensors 102 represents a first placement of the at least three sensors. The notation of “b” by each of the at least three sensors 102 represents a second placement of the at least three sensors. The notation of “c” by each of the at least three sensors 102 represents a third placement of the at least three sensors. The notation of “d” by each of the at least three sensors 102 represents a fourth placement of the at least three sensors.



FIGS. 4c-4f represent placement of five sensors 102 on a vehicle 500 from a perspective, rear, side, and top view respectively. The placement of the five sensors 102 in connection with the zone of detection 300, transmission depth 108, and transmission circumference 122 in relation to the vehicle 500 further provides that the signal is only received by one of the five sensors 102 at a time.



FIG. 5 represents the operating system 200 of the 360 safety system 100. The operating system 200 includes a CPU (central processing unit) 204, a HMI (human machine interface) 202, a key position input 210, a headlight detection input 211 (i.e. a headlight switch position input), the transmission fob 120, and the at least three sensors 102. The operating system may further include a power source 208, at least three sensor CPUs 114, an interrupt 212, and optional mobile device application 214.


The HMI 202 displays outputs from the CPU 204, such as display of an operation mode, operating system status, and prompts for user inputs. The HMI 202 further provides for user inputs, such as the selection of an operation mode and the entry of user access codes, administrator codes, and emergency override codes. The HMI may include a LCD, a LED, an OLED, a vacuum fluorescent, or other display adapted to show alpha-numeric readings. The HMI 202 electrically communicates with the CPU 204. The HMI 202 may be in hardwire electrical communication with the CPU 204. Alternatively, the HMI 202 may be in wireless electrical communication with the CPU 204, such as utilizing a wi-fi network, radio transceiver, or the like to electrically communicates with the CPU 204.


The at least three sensors 102 determine the detection of the signal from the transmission fob 120, and may be implemented as described herein.
