2011 Tundra Will Feature Trailer Sway Control
Toyota quietly announced some updates to the 2011 Tundra last week, one of which included a veritable bomb-shell: the 2011 Tundra will include a trailer sway control system as a standard feature. Obviously, this is big news for anyone who intends to tow with the Tundra.
Other changes for 2011 include:
- A smart throttle / brake throttle override system that we described a few months back
- A new dual VVT-i system for the 4.0L V6 Tundra
- Some minor interior changes – the cigarette lighter and ashtray are gone, and the headrests have been slightly modified (NOTE: The 12V power outlet is still there, just no lighter)
- Likely (yet still unconfirmed), the 2011 Tundra’s tow ratings will be reduced 300-500 lbs across the board. This is because Toyota has decided to adopt a new trailer tow rating standard developed by the Society of Automotive Engineers (SAE). This new standard will help to equalize the tow ratings that all manufacturers advertise (you can learn more about the new tow rating standard here).
- A small price increase on some models – no more than $500.
We’ll publish interior pics just as soon as we can. Hopefully, we’ll get our hands on some sales info soon.
Trailer Sway Control A Great Addition
Ever since Ford debuted an integrated trailer brake controller in the Superduty in 2003, they have been the leaders in truck towing technology. Ford was the first to integrate a brake controller, and that advancement allowed them to create a sophisticated sway-control system a few years later. While Toyota’s new trailer sway control system may not have the same level of functionality as the Ford system, it is definitely a step in the right direction.
We’ll learn more about the Tundra’s system soon, but it’s likely that the Tundra’s integrated VSC system already has many of the sensors needed to adapt some sort of trailer controls. By measuring the roll rates and yaw of the vehicle using the existing sensors, the vehicle’s computer system can probably detect a trailer that’s out of control. Then, using the existing ABS and traction control systems, brakes can be applied at individual wheels to bring the trailer under control.
See the video below for a solid explanation of Ford’s system.
Based on this description, the integrated trailer brake controller doesn’t seem essential in Ford’s system. However, having said that, it seems logical that the integrated brake controller would be a part of any sway control system…one of the advertised benefits is the enhanced braking performance that results from direct communication between the vehicle computer and the trailer.
Toyota was very wise to copy Ford’s trailer sway control system – let’s hope that they also move to copy Ford’s integrated trailer brake controller too.
If anyone knows the role that the integrated brake controller plays in Ford’s sway control system, please share below.
