Toyota will gradually roll out "Plus Support" for new vehicles and the retrofit "Pedal Misapplication Acceleration Control System II" for existing vehicles in Japan to help prevent various accidents caused by accelerator pedal misapplication; aiming to provide drivers with even greater safety and security

Toyota Motor Corporation (Toyota) has developed a new Acceleration Suppression System that will help in further curbing serious accidents as well as reduce damage caused by misapplication of the accelerator pedal. Toyota has launched this system as ‘Plus Support’ for new cars and added the function in the "Pedal Misapplication Acceleration Control System II" retrofit device for use with existing cars. Toyota introduced Intelligent Clearance Sonar (ICS) in 2012 for new vehicles and had launched a retrofit ‘Pedal Misapplication Acceleration Control System' for existing vehicles since 2018.

According to data confirmed by Toyota, ICS helps prevent roughly 70 % of all potential accidents that could occur due to accelerator pedal misapplication. However, new technologies needed to be developed to reduce the remaining number of accidents, including accidents in situations where obstacles are absent. These existing systems help prevent accidents caused by accelerator pedal misapplication when sensors detect obstacles such as a wall or glass.

At the development phase this time, Toyota first looked at actual accidents where the cause was determined to be accelerator pedal misapplication, particularly analysing situations where the accelerator pedal was pressed fully. The characteristics of these situations were then compared with big data collected from Toyota's connected vehicles.

By eliminating instances where it was determined that drivers were genuinely required to rapidly accelerate intentionally, such as when turning right or accelerating from a temporary stop, Toyota was able to identify and compute instances of accelerator pedal misapplication. In turn, this allowed for a function setting to reduce the number of accidents caused by accelerator pedal misapplication by controlling acceleration even in the absence of obstacles.
