Toyota not only does their own original accident investigation but also collects many domestic and international accident data to create a safer car.
By using a collision simulator, real vehicle collision experiments were done repeatedly to help develop an excellent body structure and passenger safeguard equipment.
From this, Toyota makes improvements to help create a car that help reduce injuries to the passenger in a possible accident.
The extensive experiments are done at Toyota's Safety Research Institution, which has facility about 39,000 square meters and a total floor space of about 44,000 square meters; 280 meters long and 190 meters wide at max.
The all-weather-condition collision testing ground is made up of 2 barrier collision lanes and a car-versus-car lane. The car-versus-car lane carries out a 2 ton car collision experiment at maximum speeds of 140km. Vehicle collision experiments of different speeds and angles at a 15 degree pitch can also be conducted in this lane.
The collision experiment ground is also capable of conducting various forms of experiments for induced rollover accident.
