ELD or Electronic Logging Device records a particular vehicle's parameters via its synchronization to the engine. It enables entries associated with a driver's RODs or record of duty statuses for strictly complying with prevalent regulations. Take a close look at the below-mentioned pointers.
Can electronic logging devices be used on any wireless gadget or smartphones?
According to top-notch professionals setting diverse log rules, an ELD could most surely be utilized on smartphones as well as wireless gadgets but only if the latter could meet the former’s technical specifications that include being capable of accessing data from a particular vehicle’s engine. A portable electronic logging device is generally installed in a definite position so that drivers could easily view it while operating their cars or trucks. Researches have effectually manifested that GPS-enabled cell phones can never properly record distances but only a gadget listed as well as certified by FMCSA would be considered compliant.
What are the major requirements of an E?LD rule
There are four major requirements that people must take into account when it comes to an ELD rule. Commercial drivers use electronic logging device to prepare record of duty statuses (RODs) and hours of service (HOS).
Setting ELD design standards and performance in accordance with FMCSA protocols.
Establishing exactly what type of supporting documents carriers and drivers must always keep with themselves.
Prohibiting persecution of drivers based upon information gathered by connected ELD technology or other fleet management systems. This particular rule also applies if a driver thinks he or she has been harassed in the past.
How does an ELD save drivers’ money and time?
As per the assumptions specified by FMCSA in its regulatory impact evaluation for the ELDs, a driver could not only save substantial amounts of time but enough money as well. $487 for filling RODs, $56 for submitting RODs, $120 for filing RODs , and $42 for removing the log books. Thus, $705 is saved in just a year.
When ELD rule went into effect?
Highly competent and adequately experienced specialists who is involved with fleet vehicle tracking management said that the ELD rule went into effect on 18th December 2017 unless the drivers are making use of grandfathered AOBRD. A grandfathered AOBRD could be loosely defined as a device that a motor carrier needs to install and implement. It should also meet needs of 49.CFR 395.15. Grandfathered AOBRDs could be used up to 16th December 2019.
Who needs to comply with an ELD rule?
The ELD rule can be applied to almost all motor carriers and drivers but there are few exceptions that you must remember. Drivers who can function under short haul can continue utilizing timecards. Drivers who make use of paper logs for at least eight days out of a one month. Drivers operating power units which is a part of tow away shipment. Drivers who are towing or driving recreational vehicles.
The Federal Motor Carrier Safety Administration (FMCSA) requires all interstate commercial truck and bus companies to utilize EOBR or electronic onboard recorder. Thisstep is aimed to helpdrivers of commercial motor vehicles (CMV) track their hours of service (HOS)on a regular basis and increase all-round safety of the vehicle and the consignment if any. Further ELD mandate helps businesses by cutting unnecessary paperwork.
According to FMCSA a common vehicle driver fills out around 230 records of duty status (RODS)each year. The mandate is proposed to save each vehicle driver about 18+ hours utilized to complete and send documented driver logs. Moreover, paperwork for documentation savings for each vehicle driver every year is calculated to be approximately $700.
Any wireless device or even an android phone may be substituted for an electronic onboard recorder provided the piece matches the technical needs and is registered and certified with the FMCSA. Anelectronic onboard recorder may also be of assistance in order to calculate the fares or generate a cost of the distance travelled and the duration that the particular engine has been running.
The installation of the hardware manufactured by ELD Mandate is lucid and does not require a technician. Their software platform is extremely user friendly and easily comprehendible. Further, their team of amiable professionals are alwaysready to offer you a demo and answer all your questions, now and in future.
Certain log rules are to be adhered to. For instance a motor carriermust keep both the electronic onboard recorder or EOBR records of hours of services data and a back-up copy of that data on a separate device for a period of six months. The fleet operator or commercial motor carrier must ensure that these records are stored securely to protect driver privacy.
All ELD data file output are standard or delimited file, a driver may import the data output file into Microsoft Excel, Word notepad, or other common tools. A driver will also be able to access EOBR records through a screen display or a printout, depending on the design of the hardware.
In case a driver decides to use a local EOBR with Bluetooth capabilities, the authorized safety official will promptly activate Bluetooth on his or her computing device and the driver will then initiate the Bluetooth electronic transfer of the data from the driver’s EOBR to the concerned safety official’s computing device.
The official will also provide a Bluetooth pairing code for the driver to enter into the EOBR for the data file transfer.
The plug-in device to a commercial truck’s Engine Control Module or ECM communicates the relevant data to software on the individual carrier’s smartphone – the software enables the log to work, the electronic pre-trip/post trip inspection reports are created in a similar fashion.
The ECM plug-in communicates with your smartphone, as with many others, over Bluetooth, and several comprehensive and guiding smartphone apps are presently available on both IOS and Android platforms. Administration of the data is done through a web-based software program users create a unique account.

Don't Forget Your Log Rules!
Logarithm product rule
The logarithm of a multiplication of x and y is the sum of logarithm of x and logarithm of y.
logb(x ∙ y) = logb(x) + logb(y)
For example:
logb(3 ∙ 7) = logb(3) + logb(7)
The product rule can be used for fast multiplication calculation using addition operation.
The product of x multiplied by y is the inverse logarithm of the sum of logb(x) and logb(y):
x ∙ y = log-1(logb(x) + logb(y))
Logarithm quotient rule
The logarithm of a division of x and y is the difference of logarithm of x and logarithm of y.
logb(x / y) = logb(x) - logb(y)
For example:
logb(3 / 7) = logb(3) - logb(7)
The quotient rule can be used for fast division calculation using subtraction operation.
The quotient of x divided by y is the inverse logarithm of the subtraction of logb(x) and logb(y):
x / y = log-1(logb(x) - logb(y))
Logarithm power rule
The logarithm of the exponent of x raised to the power of y, is y times the logarithm of x.
logb(x y) = y ∙ logb(x)
For example:
logb(28) = 8 ∙ logb(2)
The power rule can be used for fast exponent calculation using multiplication operation.
The exponent of x raised to the power of y is equal to the inverse logarithm of the multiplication of y and logb(x):
x y = log-1(y ∙ logb(x))
Logarithm base switch
The base b logarithm of c is 1 divided by the base c logarithm of b.
logb(c) = 1 / logc(b)
For example:
log2(8) = 1 / log8(2)
Logarithm base change
The base b logarithm of x is base c logarithm of x divided by the base c logarithm of b.
logb(x) = logc(x)/logc(b)
Logarithm of 0
The base b logarithm of zero is undefined:
logb(0) is undefined
The limit near 0 is minus infinity:
Logarithm of 1
The base b logarithm of one is zero:
logb(1) = 0
For example:
log2(1) = 0
Logarithm of the base
The base b logarithm of b is one:
logb(b) = 1
For example:
log2(2) = 1
Logarithm derivative
When
f (x) = logb(x)
Then the derivative of f(x):
f ’ (x) = 1 / ( x ln(b) )
For example:
When
f (x) = log2(x)
Then the derivative of f(x):
f ’ (x) = 1 / ( x ln(2) )
Logarithm integral
The integral of logarithm of x:
∫logb(x) dx = x ∙ ( logb(x)- 1 / ln(b)) + C
For example:
∫log2(x) dx = x ∙ ( log2(x)- 1 / ln(2)) + C
Logarithm approximation
log2(x) ≈ n + (x/2n - 1)
