The "Toyota Safety Technology Media Tour" is being held for domestic and foreign media on Nov. 12 (Mon.) and 14(Wed.) at the Toyota Motor Corporation (TMC) Higashi-Fuji Technical Center (Susono City, Shizuoka Prefecture).
Toyota considers the elimination of traffic fatalities and injuries the ultimate goal of a society that values mobility, and is therefore conducting research and development on individual onboard safety devices and systems based on its Integrated Safety Management Concept*1, an approach that gives direction to safety technology and vehicle development. Toyota is pressing forward with the development of safer vehicles and technologies and is intensifying its wide-ranging traffic-safety initiatives by participating in the development of safer traffic environments and promoting traffic safety education.
The technologies unveiled in the Media Tour include the safety systems such as the Pre-collision System (PCS), Intelligent Clearance Sonar (ICS), Drive-start Control, Pop-up Hood (PUH), and the Intelligent Transport System (ITS) test site which conducts research and development on next-generation vehicle-infrastructure cooperative systems, which are part of Toyota's initiatives aimed to eliminate traffic casualties.
*1 Integrated Safety Management Concept: Coordinating the individual safety technologies and systems used in vehicles. It embodies Toyota's thinking on future safety technology and vehicle development.
The newly developed PCS uses millimeter-wave radar to detect the risk of a rear-end collision with a preceding vehicle, with the system warning the driver via sound and display alerts to prompt braking when such a risk is detected. When the driver applies the brakes, PCS enables deceleration of up to 60 km/h*2 by greatly increasing the braking force up to twice*3 that of the average force applied by drivers. If the brakes are not applied, automatic deceleration*4 of 15 km/h to approximately 30 km/h*5 is possible.*6
*2 When the driver’s car is traveling at 80 km/h and the preceding car is traveling at 20 km/h
*3 According to analysis of U.S. accident data
*4 Deceleration when no brake is applied is initiated from 15 km/h
*5 When the driver’s car is traveling at 50 km/h and the preceding car is traveling at 20 km/h
*6 Full capabilities may not be possible in certain road environments or under certain weather conditions
When the clearance sonar detects an obstacle the vehicle is at risk of colliding with, such as a wall, when starting off in a parking garage or other similar environment, the system sounds an alarm, reduces engine or motor output and automatically applies the brakes.
If the vehicle gear stick is erroneously shifted when the accelerator pedal is applied, or if other abnormal gear shifting is detected, a warning is displayed and engine or motor output is reduced to limit sudden starts or acceleration.
