A few years back, sudden unintended acceleration (or SUA) was the talk of the town with numerous accidents attributed to the issue. Toyota, however, wants to eliminate the possibility of SUA it all together.
The Japanese automaker will soon be launching their new Acceleration Suppression Systems in addition to its already existing system. Called Plus Support and Pedal Misapplication Acceleration Control System II, the systems will help further deter serious accidents and reduce damage caused by the misapplication of the accelerator pedal.
As mentioned above, this isn't Toyota's first “anti-SUA” system. The automaker already has a similar safety feature in place as early as 2012 called Intelligent Clearance Sonar (ICS). In 2018, they launched a retrofit "Pedal Misapplication Acceleration Control System" for existing vehicles. Instead, the two new systems are intended to further reduce the possibility of accidental acceleration occurring.
Unlike Toyota's previous systems, Plus Support and Pedal Misapplication Acceleration Control System II can suppress accelerator pedal misapplication even without detecting obstacles in front of the vehicle. The automaker was able to roll out the new system by determining instances when drivers were required to accelerate intentionally and when they were not. Interestingly, Pedal Misapplication Acceleration Control System II engages even when reversing and when no obstacles are present.
Plus Support will be made to all Toyota vehicles equipped with ICS in the future. However, it will first be introduced in the Prius and Prius PHV, and be rolled out to other models eventually. It will be gradually rolled out to other models in the future. The system works automatically when vehicle doors are unlocked using Plus Support Smart Key, which is an extra dealer option. When doors are opened using a conventional key, Plus Support is not activated.
Meanwhile, Pedal Misapplication Acceleration Control System II is used as a retrofit for existing models already equipped with the earlier system. It is set to launch in November 2020 for the Sai and in January 2021 for the Crown and Mark X vehicles.
Hopefully, we get to see these safety systems in local models. Toyota Safety Sense is already available on the Corolla Altis Hybrid, Alphard, and HiAce Super Grandia. Plus Support and Pedal Misapplication Acceleration Control System II will surely make Toyota models much safer.
