The electronic system updates, now in production, enable Kenworth to easily integrate new options into its trucks, while also simplifying wiring, providing control system feedback to drivers — switch visual cues, for example — and leveraging DAVIE4 diagnostic tools to speed service and repairs. In addition, Kenworth has simplified the process for connecting telematics and electronic body controls to the truck electronic system by providing an industry-standard interface, according to an announcement.
“We’ve always been focused on being the industry leader in electrical and electronic system performance, and we’re raising the bar again with the latest advances in multiplexing and smarter, more intelligent controls,” says Patrick Dean, Kenworth chief engineer. “With trucks becoming smarter through highly integrated computer systems, we have transitioned from traditional point to point wiring to electronic networking. This has allowed for the simplification of wiring harnesses, reduction of the number of physical wires and improved flexibility.”
A part of this new update is the introduction of an advanced vehicle electronic control unit. This central control module is the brain of the electronic system and has significantly more capacity and speed, setting the stage for additional future releases, including advanced driver assistance technologies and advanced powertrains, the company says.
For Kenworth vocational customers using Paccar MX engines, they will notice a difference immediately.
“With our new electronic architecture, the customer will get additional Paccar MX engine PTO functionality, including further options for locating body controls, increased engine speed set-point flexibility, smart and programmable interlocks with other vehicle operation parameters and enhanced driver feedback on the instrument panel’s 5-in. digital display and on the switches themselves,” Dean says. “For example, the PTO engagement switch will only illuminate if all the necessary interlocks are satisfied. If those interlocks are not satisfied, the central dash display will also tell the driver why.”
While that might seem like a small, incremental advancement, Dean adds, it is fundamental to Kenworth’s focus on putting the driver first and providing a high degree of flexibility.
“Our electronic offerings continue to expand rapidly. To make that work for our customers, these systems need an electrical architecture that is easily adaptable and simplifies their operations,” he says. “It’s a new era where plug-and-play connectivity is the requirement — and this is what we are giving our customers to support clean installations today, while also simplifying future updates and expansion of the system.”
