The Pursuit of Vehicle Safety

Toyota strives to achieve real-world safety from the standpoints of active safety technology (which helps to prevent an accident from occurring) and passive safety technology (which helps to reduce the extent of injury when an accident occurs). Real-world safety is a concept based on the investigation and analysis of various actual traffic accidents and then developing, spreading, and verifying the effectiveness of new technological countermeasures. In order to do this, Toyota first uses data from accident investigations and human research to analyze why accidents occur and what are the causes of injuries.

Next, we recreate accidents through a variety of simulations and then develop technological countermeasures. In order to clarify the mechanisms that cause injuries during an accident Toyota makes use of technologies such as THUMS, a virtual human model for computer collision analysis, which was developed independently by Toyota. Furthermore, we have also developed a driving simulator to create a testing environment that is as close to real-world driving as possible in order to promote the development of active safety technologies. This simulator is used for special testing, such as when driving an actual vehicle would be dangerous or when the vehicle is to be driven under very specific conditions.

In addition, Toyota is always striving to improve the safety of its vehicles through thoroughly checking the effectiveness of its safety technologies. These technologies are checked through a continuous cycle of actual on-vehicle tests and other measures that include accident investigation and analysis in the marketplace even after the vehicle has been put on sale.
