Titan Class 3-8 Truck - Automatic system for powertrain transmission applications. Test stations designed and built to simulate a fully functional commercial truck. Using two VFD Controlled Electrical Motors these stations simulate the input shaft from the engine and the output shaft from the drivetrain to make these transmission feel like they are at home in the truck they are meant for. Automatic transmissions commanded via CAN bus from a simulated Driver Interface Device (DID) to engage FNR gears. The transmission determines shifting points based on input/output shaft speeds, requested acceleration, and torque. These are CAN-based systems with the transmission controller and the engine simulation control working in harmony to apply the right amount of torque, engage/disengage the clutch, command the shift, and to smoothly transition from one gear to the next. The system includes a full computer-based NVH system incorporating accelerometers, microphones, laser vibrometers, torque and speed sensors. Live data is captured for the full test of the transmission, recording live data at up to 10khz per channel.
These test stations are designed and built to simulate a fully functional commercial truck. Using two VFD-controlled electrical motors, they simulate the input shaft from the engine and the output shaft from the drivetrain, replicating real-world operating conditions for the transmission. These automatic transmissions are commanded over the CAN bus from the simulated Driver Interface Device (DID) to enter FNR gear. The transmission determines the next shifting point based on the combination of input shaft speed, output shaft speed, requested acceleration, and torque. These are CAN-based systems with the transmission controller and the engine simulation control working in harmony to apply the right amount of torque, engage/disengage the clutch, command the shift, and smoothly transition from one gear to the next.
Built into this system is a full computer-based NVH system incorporating accelerometers, microphones, laser vibrometers, torque and speed sensors. Live data is captured for the full test of the transmission, recording at up to 10 kHz per channel. Not only is all sensor data streamed to disk, but CAN data is also recorded on up to 4 CAN busses. This recorded CAN data and DTCs are stored alongside and aligned with the sensor data to allow for quick charting and inspection. Test data is serialized for every test of every transmission.
The Ascential T&M Class 3-8 Truck - Automatic test system is designed for powertrain transmission applications. It simulates a fully functional commercial truck using two VFD controlled electrical motors to simulate the input shaft from the engine and the output shaft from the drivetrain.
