1 JITI Safer Vehicle Seminar Toyota s Safety Initiatives Toyota Motor Corporation March 20, 2013

NHTSA, IIHS and Consumer Reports have been introducing tests to encourage installing

2 Countermeasures taken into vehicles 1. Manufactures have continued developing and innovating various safety technologies. 2. NHTSA, IIHS and Consumer Reports have been introducing tests to encourage installing technologies into vehicles

3 Countermeasures taken onto traffic environment 3. FHWA and state governments efforts on improving traffic environment. 3

4 50,000 40,000 Traffic Accident Trends in US Fatality rate and injury rate have been decreased by about one-third in the over last two decades. Fatalities Injuries (x 100) 30,000 20,000 10, Traffic Safety Facts

5 Crashes by Manner of Collision, etc. (2010) To further reduce both fatalities and injuries, many more countermeasures are required to avoid crashes. Non Collision (Rollover) Pedestrian Collision with Object Not Fixed Rear End Angle Head On Non Collision (Rollover) Pedestrian Collision with Object Not Fixed Collision with Fixed Object Rear End Collision with Fixed Object Sideswipe Sideswipe Head On Angle Fatal Crashes (30,196) Injury Crashes (1,542,000) Traffic Safety Facts

6 Driving Simulator The aim of the Driving Simulator is to investigate driver behavior that could result in crashes. World-leading range of movement High-definition computer graphics with a driver s view of 360 degrees * 20m = about 65 feet 35m = about 114 feet 6

7 Pursuit of Real-world Safety Learning from actual accidents, simulating how crashes happen, developing countermeasures, and examining their performance in future actual crashes. Crash investigation and analysis Vehicle development & testing Simulations 7

8 Rear End Collisions Rear end collisions are a major cause of vehicle injuries. Rear End Rear End Fatal Crashes Injury Crashes Traffic Safety Facts

to enhance driver s braking effort, and when the system

9 Pre-Collision System (PCS) To avoid or mitigate rear-end crashes, PCS is designed to sound an alarm to warn a driver, to enhance driver s braking effort, and when the system detects that a crash is unavoidable, to apply brakes automatically. 9

Enhancement of PCS - For drivers who apply the brakes, New PCS could help decelerate by as much as 40 mph on average. - For drivers who do not brake, PCS could decelerate by as much as 20 mph.

10 Enhancement of PCS - For drivers who apply the brakes, New PCS could help decelerate by as much as 40 mph on average. - For drivers who do not brake, PCS could decelerate by as much as 20 mph. PCS warning test results Driving Simulator Did not apply the brakes 13% Applied the brakes 87% Test group: 113 males and females from 20s to 60s Effect of enhanced driver s effort Relative velocity with preceding vehicles Without a PCS Deceleration of up to 40 mph With a New PCS 1 Effect of automatic braking Relative velocity with preceding vehicles Deceleration of up to 20 mph 2 1 Preceding vehicle at 20 km/h, subject vehicle at 80 km/h 2 Preceding vehicle at 20 km/h, subject vehicle at 50 km/h Note: Results dependent on weather and road conditions 10

11 Pedestrian Accidents Pedestrian accident do not show high percentage of pedestrian fatalities and injuries in crashes, but Pedestrian Pedestrian Fatal Crashes Injury Crashes Traffic Safety Facts

12 (Vehicle occupant) Traffic Accident Trends in US by Person Type Pedestrian fatalities have not been apparently decreasing in the past decade. (Pedestrian, Motorcyclist, Pedal-cyclist) Vehicle occupant Pedestrian 4,280 Motorcyclist Pedal-cyclist Traffic Safety Facts

4% Low beam NASS-PCDS(1994-1998) A High-beam is activated at all times

13 Automatic High Beam (AHB) Pedestrian fatalities by day and night Pedestrians Day 53.6% Night 46.4% Low beam NASS-PCDS( ) A High-beam is activated at all times so that pedestrians could be noticed earlier. Toyota is planning to extend AHB roll out to include compact vehicles. 13

Pedestrian Stereo camera Near-infrared emitter Millimeter-wave radar Possibility of collision detected High collision risk

14 Pre-Collision System (PCS) for preventing pedestrian accidents The PCS with pedestrian detection rolled out in 2013MY Lexus LS. It is designed to avoid the collisions at speeds up to 25 mph. Pedestrian Stereo camera Near-infrared emitter Millimeter-wave radar Possibility of collision detected High collision risk Avoidance impossible Collision A Pre-collision Brake Assist on standby Warning A B Pedestrian B Pre-collision braking (Automatic braking) * Depending on weather and road conditions 14

15 Pre-Collision System (PCS) for preventing pedestrian accidents * 40km/h = about 25mph 15

16 Lane departure crashes Head on collisions and collision with fixed objects account for a major portion of both fatal crashes and injury crashes. Head On Collision with Fixed Object Collision with Fixed Object Fatal Crashes Head On Injury Crashes Traffic Safety Facts

17 Vehicle Stability Control (VSC) VSC helps the driver maintain control of the vehicle when lateral skidding occurs after sudden steering changes and when driving on slippery surfaces. Without a VSC Without a VSC With a VSC 17

18 Lane Keeping Assist (LKA) LKA warns a driver when the system senses the risk of departing from a lane. It also adds steering reaction forces so that the driver maintains his/her proper lane. 18

19 Intersection crashes Angle collisions represent a major portion of both fatal crashes and injury crashes. Angle Angle Fatal Crashes Injury Crashes Traffic Safety Facts

Vehicle-to-Infrastructure and Vehicle-to-Vehicle Cooperative Safety System Toyota is trying to promote the development and the realization of both systems in parallel with government activity.

Crossing collision Notification of approaching vehicle in hidden area Left-turn accident Notification of oncoming traffic and pedestrian presence on crosswalk Oncoming vehicle Turning left Pedestrians 20

21 The Intelligent Transport System (ITS) Proving Ground The aim of the ITS proving ground is to establish early countermeasures to prevent intersection crashes. - Area: 8.6 acre - 5.8GHz & 760MHz - Pedestrian detection sensors - Vehicle detection sensors 21

22 Future: Automated Vehicle Technology Automated driving technology will be integrated into the driving support systems in the next generation. Automated driving development 360 degree LIDAR GPS Side facing cameras Traffic signal recognition Vehicle recognition 22

23 Integrated Three-part Initiative Integrated Three-part Initiative is the most effective approach to create traffic safety society. People Vehicles Integrated Three-part Initiative Traffic Environment 23
