Natural language processing tools that use AI like ChatGPT or Google Bard are becoming more popular, enabling people to have conversations with computers.
Many of these NLP tools build their language models by using publicly available information. For instance, OpenAI relies on three sources of information: what’s available on the internet, information licenses from third parties, and information users and human trainers provide. This “training process” not only supplies the AI tool with lots of information but also allows it to pick up on language patterns so it can become a more proficient communicator.
At times, the response you get from an AI tool is not only impressively fast, but also dead-on accurate. At other times, the response can be a little off. That’s why tools like ChatGPT and Bard recommend fact-checking “important” information. But doesn’t that defeat the purpose of using an AI tool in the first place, where one of the primary benefits is reducing time to insight?
ChatGPT vs. Trucking experts
How often should I clean the DPF on my Kenworth truck?
ChatGPT: Cleaning the Diesel Particulate Filter in a Kenworth truck depends on various factors like driving conditions, mileage, and manufacturer recommendations. Typically, it’s recommended to inspect and potentially clean the DPF every 150,000 to 300,000 miles, but this can vary based on your specific truck model and usage patterns. It’s advisable to consult your truck’s manual or the manufacturer’s guidelines for precise maintenance schedules tailored to your vehicle.
Person: Steve Hoke, president of Diesel Emissions Service: That response is spot on from a manufacturer’s point of view. But real-world results would prefer that a DPF be cleaned in the 100K-150K range for the best longevity of the DPF.
What is the best oil filter for a Detroit DD15 engine?
ChatGPT: The choice of the best oil filter for a Detroit DD15 engine may vary based on factors like specific model requirements and personal preferences. However, reputable brands such as Fleetguard, Baldwin, and Donaldson are often recommended for DD15 engines due to their quality and compatibility. It’s crucial to consult your engine’s manual or manufacturer recommendations to ensure you choose an oil filter that meets the required specifications for optimal performance and engine protection.
Person: Len Copeland, product marketing manager for Detroit Components: While we acknowledge that AI has become influential technology, we still recommend our own branded oil filters for our engines. All of the recommendations are on our publicly accessible Techlit webpage at dtnatechlit.com/portal-public/ (search for “Supplemental Oil Filters”).
How can I improve efficiency in my truck repair shop?
ChatGPT: There are several things you can do:
- Streamline the repair process
- Employee training
- Utilize technology
- Regularly maintain your repair equipment
- Clear communication
- Set standard operating procedures
- Customer service focus
- Performance monitoring
Person: Jacob Findlay, Fullbay founder and chairman: The best thing a shop can do is grab a pencil and blank sheet of paper and draw out what the repair workflow is today. Identify the areas where time and/or cost tend to get out of control, and find ways to do things more efficiently. Also, be sure to measure technician efficiency, which is invoiced hours divided by total hours worked. Publish the results so the Hawthorne Effect can play out (which says people change behavior when behavior is being evaluated). Once the key metrics and processes are laid out, set some goals and continuously monitor them.
Person: Nick Pittinger, director of data services at Decisiv: Streamlining communication between the fleet, shop, and suppliers is one of the best ways to improve efficiency. When communication is consistent and clear, the repair event typically goes much smoother and faster. Leveraging standardized operations will also improve efficiency, and is much better than leaving each technician to figure things out for themselves. Improving workflows by automatically assigning tasks through a software platform will also help save time. Finally, shops should find ways to measure performance, analyze that data to identify bottlenecks, and use it to get a little bit better and faster.
ChatGPT vs. Predictive maintenance
For our predictive maintenance showdown between man and machine, we asked the free version of ChatGPT some predictive maintenance questions and vetted those answers with some human experts.
What indicators should a fleet manager look for to determine the readiness of their company for integrating predictive maintenance components?
ChatGPT: Fleet managers should scrutinize key indicators such as ensuring effectiveness in the current preventive maintenance process, considering fleet characteristics such as age and mileage, and evaluating engagement with telematics providers for dynamic solutions. Collaboration and customization play a pivotal role, aligning implementation plans with fleet goals. Integration into existing workflows, addressing education gaps, and prioritizing technician training are essential. Additionally, the company's capability to handle data influx and prevent overload should be considered. By comprehensively examining these factors, fleet managers can determine the preparedness of their company for the seamless integration of predictive maintenance components.
Andrew Bartholomew, associate product marketing manager, Fleetio: It’s not that complicated! An ideal indicator for us would be when an increasing proportion of downtime or repair spend is resulting from repairs that couldn’t be avoided with a comprehensive preventive maintenance system. Essentially, if a fleet’s preventive maintenance process is in order, it’s easier to think ahead; there aren’t going to be as many unexpected issues popping up and taking all of the focus.
How can a predictive maintenance algorithm and software adapt to changes in how a fleet operates or how they grow over time?
ChatGPT: A predictive maintenance algorithm and software can adapt to changes in a fleet's operations and growth by being dynamic and scalable. These systems can accommodate new vehicles, changes in regulatory compliance, energy transitions, and even the integration of autonomous vehicles. Telematics providers, who often offer these solutions, collaborate closely with fleets to custom tailor implementation plans, ensuring flexibility. The algorithms incorporate advanced AI techniques to process and prioritize fault codes. This adaptability allows the system to remain effective as the fleet undergoes operational shifts or experiences growth, ensuring that predictive maintenance continues to deliver meaningful insights and benefits over time.

James Rice, president, Uptake: In the last probably 6 to 8 months, I'd say our models and process with the algorithms have actually even gotten down to the asset level. We're taking a little bit more into account at the asset level as opposed to component or fleetwide data that says all 2,000 of my Freightliners should act the same. The ones in California aren't going to act the same as those in New York. When you have the baseline foundation of what it should be, but if you're in an extreme weather event or extreme temperature, we're not going to automatically say there's a problem.
We'll look and determine if there’s an anomaly, and if it’s sustainable. Is it a weird thing for the day, or is it really outside the normal operating measure? That has been how this product is evolving and as data scales, we will continue to build out the power of these algorithms.
At what level of sophistication should fleets commence their implementation of an AI-driven predictive maintenance component?
ChatGPT: It depends on various factors, such as the fleet's size, operational complexity, and existing technological infrastructure. It's recommended for fleets to conduct a thorough assessment of their specific needs, considering factors like the age of their vehicles, maintenance history, and the desired level of automation. Starting with a phased approach, integrating AI gradually, and scaling based on successful outcomes can be a strategic way to ensure effective implementation without overwhelming the existing operations.
Alan McMillan, president, Intangles: No, it's really straightforward. We plug into their CANBUS through their OBD port. Even if they have something in the OBD port, we just put a pigtail in. In almost all of our installations, there’s already a GPS device or an ELD device running in that vehicle. It's no problem to run alongside that, and frankly, the truck driver doesn't even know we're pulling all that information back to command center. It's all done through the cloud and naturally, we're also doing things like driver behavior. We do all sorts of predictions around that.
What challenges would you advise to be mindful of during the integration of a predictive maintenance solution?
ChatGPT: The answer would depend on the insights and experiences of individuals involved in the integration of predictive maintenance solutions. They might discuss challenges related to technology adoption, data management, technician training, or overcoming hesitancy in embracing new approaches to fleet management.
Vedant Khattar, CTO, Pitstop: Don't think it will just start working out-of-the-box. Each company has a different threshold of what is critical and what is minor, so you have to give it at least like two to three months because every model takes some time to calibrate. You really need patience working with a new system like this, so don't get frustrated if the system says something is a critical issue but when you check it was only a minor issue. Those incidents will happen. If it’s reported and then happens again, then it is a problem. But if it happens one time and the computer has learned and improves, it’s only going to get better from there.
ChatGPT vs. Emails
