Q

4.3.3 What is a differential correction system? (p.120)

A
  • If greater accuracy is necessary, a system called differential correction can be used.
    • Requires a second receiver tuned to the signal of a stationary base station on the ground even if relayed by communications satellite
    • A correction factor to the known, surveyed point can be computed to improve the GPS location determined by using the satellites
    • The use of a base station signal eliminates the inaccuracies introduced by the various layers of the atmosphere (e.g., ionosphere and troposphere), signal noise, clock drift, and other sources that affect the satellite signals

A
  • Geofence is simply a defined area on the map with a given location defined by the geo coordinates

35
Q

4.7.7 What key areas can telematics help to monitor driver behavior in? (p.129-130)

A

• Vehicle Idling monitoring: reduction of fuel usage / engine idling is harder on the engine than an hour of driving time > higher maintenance cost.
• Idle Time Monitoring: telematics allows for monitoring when drivers are physically idle and potentially not doing their job.
• Speed Monitoring: As a high priority safety issue, the ability to monitor speed is one of the key features of telematics.
• Harsh Braking / Harsh Acceleration / Harsh Swerving: Some telematics solutions have incorporated a G-force sensor/accelerometer that captures

36
Q

4.7.8 How can telematics help facilitate vehicle inspections? (p.130)

A
  • Pre-trip and post-trip inspections of vehicles can be facilitated by telematics
  • This allows a driver to key in their inspection findings, and to have major and minor defect information captured immediately with a real time notification to maintenance staff.
37
Q

4.8 Integrate telematics data

A
  • The telematics data is useful in managing fleet operations in various ways. It is often interfaced to the FIMS.
38
Q

4.8.1 What benefits can access to location data bring to your fleet? (p.131)

A

• Optimizing utilization of your fleet:
• Improved customer service: telematics allows for dispatching the closest vehiclee
• Driver management:
• Incident management: The ability to review the where and how the vehicle was being driven is of great benefit to validating or disputing incident claims

39
Q

4.8.2 What are the benefits of using telematics to monitor meter readings? (p.131-132)

A
  • The ability to automatically gather meter readings, particularly odometer & engine hour readings allows you to manage the preventive maintenance (PM) schedules using actual data in real time from the fleet
  • In fact, some telematics solutions provide the PM forecasting and scheduling application or the meter readings from telematics are imported to the FIMS for the FIMS to create the PM forecast and schedule.
  • Eliminate need for manual collection of readings from your fleet which are time consuming & error prone.
  • Eliminate costs from either over maintaining or under maintaining vehicles based solely on calendar scheduling.
40
Q

4.8.3 What benefits can come from capturing various vehicle parameters such as RPM and fuel levels? (p.132)

A

• Monitoring RPMs allows you to focus driver training on operators that are adding to unnecessary engine wear and tear with excessive RPMs. Managing RPMs during PTO engagement ensures that vehicles are being operated within the appropriate parameters.
• Monitoring fuel levels & associated fuel consumption allows for identifying vehicles that are operating out of normal fuel consumption ranges. This allows you to identify additional maintenance that may be required on a vehicle and also helps prioritize which vehicles you would dispose of first.

41
Q

4.8.4 How will the capture of DTC help facilitate fleet operations? (p.132)

A

The capture of diagnostic data from the ECM, also known as the DTC (Diagnostic Trouble Codes) or MIL (Malfunction Indicator Lamps) will facilitate fleet operations
by:
• Provision of real time alerts to the mechanics based on presence of DTC, ensures that vehicle issues can be addressed and prioritized as they happen.
• Elimination of “driving with the engine light on” by not relying on drivers to report check engine or other indicators.
• In the more sophisticated integrated systems, a vehicle service order can be created automatically based on the DTC/MIL coming from a vehicle without requiring intervention from driver or shop personnel

42
Q

4.9.1 What are premarket telematics solutions? (p.132)

A
  • Some vehicle OEM’s install telematics solutions at the factory while the vehicle is built
  • These solutions are called pre-market as compared to the after-market solutions
43
Q

4.9.2 What is OnStar and what services does it offer users? (p.133)

A

OnStar Corporation is a subsidiary of General Motors that provides subscription-based communications, in-vehicle security, hands free calling, turn-by-turn
navigation, and remote diagnostics systems throughout the United States, Canada and China
- Allows users to contact OnStar call centers for emergency services, vehicle diagnostics and directions
- Automatic Collision Notification is detected by airbag deployment or other sensors and automatically sends information about the vehicle’s condition and GPS location to OnStar call centers to assist emergency response efforts

44
Q

4.9.3 What is Ford SYNC and what services does it offer its users? (p.133)

A
  • The Ford SYNC system allows the driver to talk, navigate and listen to music while keeping his/her hands on the steering wheel and eyes on the road
  • NOT for Fleet Management
45
Q

4.10.1 What is a passive vehicle location device? (p.133)

A
  • A passive device will record and store data but this data will stay on the device until retrieved
46
Q

4.10.2 What is the main benefit of a passive system? (p.133)

A
  • The main benefit of the passive system is that it eliminates the cost of having a monthly data plan with the wireless carrier.
47
Q

4.10.3 What is the disadvantage of passive devices? (p.134)

A
  • The information is always after the fact
48
Q

4.10.4 What is an active vehicle location device? (p.134)

A
  • An active device is more typical and the data is sent automatically in real time or at programmed intervals.
  • These intervals are programmable and the customer specifies the interval to the supplier so that the required interval is set in the device before it is shipped
  • Data transmission can also be triggered by a significant direction change which generates a much cleaner and easier to read “bread crumb”
49
Q

4.10.5 What is a compact telematics device and what are the advantages of it? (p.134-135)

A

Several manufacturers now offer compact hardware that can be installed by plugging a single, small unit into the second- generation, on-board diagnostics port
(OBDII) standard equipment from all manufacturers selling vehicles in North America and Europe

50
Q

4.10.6 What is the disadvantage of a compact telematics device? (p.135)

A

The disadvantage is that they are also easily tampered with by the operator.

51
Q

4.10.7 What is a “Black Box” event data recorder (EDR)? (p.135-136)

A
  • The “Black Box” is the slang term for the event data recorder (EDR) present on most light-duty vehicles.
  • It generally includes throttle and brake-pedal position, steering angle, yaw rate (the vehicle’s rotational velocity), speed, and impact-sensor data.
  • EDR data has been used for several years as court evidence
52
Q

4.10.8 What are battery powered only telematics devices? (p.136-137)

A
  • For non-powered assets or “yellow iron”, the battery only powered GPS units are excellent for the “ping a day” requirements
  • These are fully self-contained, weatherproofed units that can be easily mounted on your vehicle or asset
  • manufacturers identifying battery life from 3 – 7 years depending on the product
53
Q

4.10.9 What challenges are presented if using consumer devices as a telematics solution? (p.137)

A

• Unless all your employees are mandated to use the same device, there would be many different makes and models that may be difficult for the telematics application software vendor to support.
• The changes in consumer grade devices is constant and on-going support/ maintenance might be challenging as with the next operating system (OS) upgrade, the data format may change.
• These devices also have off switches and GPS can be easily disabled.
• They are not connected to the vehicle so the ability to capture ECM data is not possible.
• No sensor inputs (e.g. PTO) is possible since the device is not vehicle-centric.
