Toyota Launches New Acceleration Suppression System(Watch its Video)

Toyota Motor Corporation (Toyota) has developed a new Acceleration Suppression System, in addition to its existing system, to help further deter serious accidents and reduce damage caused by misapplication of the accelerator pedal.

Toyota launched this system on Wednesday 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.

In 2012, Toyota introduced Intelligent Clearance Sonar (ICS) for new vehicles and since 2018, had launched a retrofit “Pedal Misapplication Acceleration Control System” for existing vehicles.

These existing systems help prevent accidents caused by accelerator pedal misapplication when sensors detect obstacles such as a wall or glass. According to data confirmed by Toyota, ICS helps prevent roughly 70 percent 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.

At the development phase this time, Toyota first looked at actual accidents where the cause was determined to be accelerator pedal misapplication, particularly analyzing 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.

Features

  • This product adds acceleration suppression functionality to the existing “Pedal Misapplication Acceleration Control System,” suppressing acceleration when pedal misapplication is detected, even if there are no obstacles in front of the vehicle.
  • In addition to the functions offered by existing systems that suppress acceleration when an obstacle is detected in front of the vehicle and suppress acceleration when reversing, this system aims to deter serious accidents and reduce damage caused by misapplication of the accelerator, regardless of whether any obstacles are present when reversing.
  • Toyota has improved the function while revising the system configuration, resulting in a product that costs 17,600 yen less than the existing product.
  • This system conforms to the performance certification system developed by the Ministry of Land, Infrastructure, Transport and Tourism in April 2020 for retrofit pedal misapplication acceleration suppression systems. (The system received the first approval from the ministry.)

By combining its existing ICS and retrofit device functions with the Acceleration Suppression function, Toyota believes it can further reduce the number of serious accidents caused by pedal misapplication in parking lots and other areas. This will enable customers, especially those worried about possible pedal misapplication accidents, to enjoy greater safety and security.

Toyota is not developing and selling these functions for Toyota vehicles alone, but has extensively shared the operational logic of the Acceleration Suppression function with other Japanese auto makers.

The declining trend in the number of road traffic fatalities in Japan notwithstanding, more than 3,000 precious lives are still lost every year. Led by the belief that “the first step in joyous mass production is safety,” Toyota intends to contribute to the elimination of traffic fatalities and injuries―the ultimate goal of a mobility society―using a three-pillar approach: 1) through improvements to car safety; 2) through educational initiatives to help inform people, such as the Support Toyota programs that promote further understanding of safety functions; and 3) through activities that seek to improve road traffic environments. At the same time, Toyota Would like to contribute to the Sustainable Development Goals (SDGs)*4 specified by the United Nations, through the approach to safety.
