Agritechnica 2022

Controller series for agricultural machinery

At the Agritechnica 2022, TTControl plans to present the TTC 2300 ECU (electronic control unit) family of the TTC 2000 controller series. It is designed for off-highway machinery, such as agricultural implements, harvesters, farm tractors, and hybrid electric vehicles.

TTControl announced the launch of the TTC 2000 series of ECU that are designed from the ground up to meet the needs of intelligent vehicles, explained the company. The series consists of complete sets of compatible ECU families with different processing power, scalable according to advanced and automated off-highway applications. The first member of this series, the mid-sized TTC 2300 family, will be presented at the Agritechnica 2022 exhibition. Customer deliveries are scheduled to begin in June 2022.

The controllers offer flexibility to reuse applications across different machine sizes and for upcoming machine generations, explained the company. The TTC 2000 series products offer scalable building blocks that make the control system expandable as needed to adapt to evolving vehicle technology. A number of available inputs/outputs (I/Os) and for example CAN as a communication interface are provided.

Centralized vehicle architecture

The ECUs are designed to be the heart of a centralized electronic architecture. This can take the form of a vehicle control unit (VCU), a safety monitor, or a head-unit controller for agricultural implements. Built for use in rugged operating environments, the controllers operate in harsh conditions and extreme temperatures.

The Isobus-compatible TTC 2300 family is TÜV safety certified. Each control unit meets safety standards from the agricultural, construction, and automotive industries, said the company. The mixed criticality approach allows both safety-critical and non-safety-critical code to run on the same CPU (central processing unit) without reducing the overall safety level. Infineon's latest controller CPU, the second-generation Aurix Tricore, provides computing power - also for future mobile machines, the company added. The product family comes with the real-time operating system PXROS for application development.

The controllers are designed for onboard connectivity and communication with IoT (Internet of Things) networks. The controllers provide processing of information from analog, digital as well as smart sensors across a range of inputs.

Prepared for sensors

So-called smart sensors are producing amounts of data to support machine functions. The TTC 2300 family enables use cases for various automation and assistance systems by providing internal memory and enabling the transmission of sensor data via standardized Sent (Single Edge Nibble Transmission) interfaces.

A forward-looking electronic control system must be able to control also electric motors in the off-highway sector. The ECUs ensure this due to H-Bridge outputs, while in parallel it can manage actuators and sensors for other machine functions, explained the company.

“The TTC 2300 ECU family stands for high processing power and a wide range of safety certifications,” said Lucian Badescu, Product Manager ECU at TTControl. “This helps vehicle manufacturers to introduce innovative safety-related features, reduce time and cost of end-product testing and validation, and develop advanced architectures for mobile machines.”
