g) increases the hydraulic pressure when the gear shift lever at the position "1".įull-time all wheel drive with 41/59 torque split front-to-rear under normal conditions. f) decreases the hydraulic pressure when the brake pedal is pressed and when the accelerator pedal is released. e) cuts off the hydraulic pressure when ABS is activated. d) increases the hydraulic pressure when the front or the rear wheels start to slip. c) decreases the hydraulic pressure when the vehicle is turning (calculated by comparing the front and the rear's driveshafts speeds). b) adjusts the hydraulic pressure when the vehicle starts moving, based on the accelerator pedal position. a) adjusts the hydraulic pressure based on the produced torque and the road conditions. The hydraulic multi-plate clutch ECU performs the following functions: In North America, if a vehicle is equipped with VDC, most likely it has a VTD type all wheel drive. Vehicles with 5-speed VTD: 6-cylinder Legacy, Legacy Outback, Tribeca (else?) Vehicles with 4-speed VTD: 2002 Impreza 2.5WRX (North American market), Forester 2.5XT (North American market), SVX (36/64 torque split), 2003 Legacy GT 4EAT+VTD, 1998-2003 6-cylinder Legacy Outback 4EAT+VTD, (anything else?) Optional viscous-type limited-slip rear differential. 
Sensors monitor parameters such as wheel slippage, throttle position and braking to help determine the amount of clutch lock. Electronically controlled hydraulic multi-plate clutch installed in conjunction with the center planetary-type differential.
With TV1/VTD 4- and 5-speed automatic transmission:įull-time all wheel drive with 45/55 torque split front-to-rear under normal conditions.
e) cuts off the hydraulic pressure when ABS is activated. 
d) decreases the hydraulic pressure when the vehicle is turning. c) increases the hydraulic pressure when the front wheels start to slip (this function deactivates when the speed exceeds 60 km/h or when the accelerator pedal is released). b) increases the hydraulic pressure when the gear shift lever at the position "1". a) adjusts the hydraulic pressure according to the accelerator pedal position and the vehicle speed. The hydraulic multi-plate transfer clutch ECU performs the following functions: Sensors monitor parameters such as wheel slippage, throttle position and braking, to help determine needed torque distribution to the rear axle. Electronically controlled hydraulic multi-plate transfer clutch installed instead of the center differential in the transaxle's tailshaft. Proactive automatic all wheel drive with 90/10 torque split front-to-rear under normal conditions (80/20 from 1996 60/40 on Subaru Forester from 2009 and on - Source). #SUBARU FORESTER FORUM VEHICLE DYNAMICS CONTROL SYSTEM CODE#
Highly reliable, automatically generated code dramatically accelerated the time, effort and documentation required for final code verification.With TZ1/ACT-4 (Active Torque Split) 4-speed automatic transmission:. This significantly improved productivity and reduced costs for the Subaru development team. The amount of automation increased to 95% for the code. By leveraging SCADE, Subaru engineers can quickly and accurately generate the mission-critical code that keeps electric vehicles running safely and smoothly, no matter how complex their technology architecture. #SUBARU FORESTER FORUM VEHICLE DYNAMICS CONTROL SYSTEM GENERATOR#
Its model-based environment and its ISO 26262 ASIL-D certified code generator eliminate the potential for human error as it translates the control logic for the ECU.
#SUBARU FORESTER FORUM VEHICLE DYNAMICS CONTROL SYSTEM SOFTWARE#
SCADE is a specialized tool for developing embedded software code. Subaru has relied on Ansys SCADE solutions to develop the software code that underlies the electronic control units (ECUs) for its electric car program. This adds new complexity to the control logic and places additional demands on Subaru's engineers to ensure the ECU's accuracy and tight control. For the Forester e-BOXER, which features an innovative, horizontally opposed engine, the ECU delivers added intelligence that balances optimal driving conditions with high fuel efficiency. ECUs are supported by millions of lines of underlying embedded software code and subject to strict regulatory oversight. The ECU that lies at the heart of every hybrid and electric vehicle ensures all of the car's electronics are integrated safely and securely. The time saved during the end-toend development of the electronic control unit (ECU) managing the hydrid/electric engine control - without sacrificing the accuracy of its control software - has been crucial to Subaru’s ability to introduce innovative, new technologies. In the race to launch new hybrid and electric vehicle models, Ansys SCADE has emerged as a valuable strategic tool for Subaru over the past decade, supporting the automaker’s commitment to uncompromising safety and quality.
