As a major producer of cars, Toyota has a responsibility
but also a great opportunity to influence for a change to
safer cars

Toyotas ultimate goal
Zero casualties from traffic accidents

Attitudes need to changes

We need a traffic environment that includes all

..but we all make mistakes

A challenge to get a clear picture of the accident

As a major producer of cars, Toyota has a responsibility](https://reader036.fdocuments.in/reader036/viewer/2022081607/5ee250cfad6a402d666cd7a9/html5/thumbnails/9.jpg)
What can we do to prevent accidents, how can we minimize the
damage of the accident?
Toyota searching for the answers in different ways
The question:

Laboratory tests do not give us a full picture

Use of a simulator can help us study complex traffic
situations in a safe way

New technologies will dramatically reduce the number of
accidents

Toyota – Folksam collaboration
• Insurance co-operation started 1990
• All Toyota cars sold in Sweden have a 3-year CDW insurance included in the price, meaning we have information of all Toyota crashes in Sweden
• The CDW is the base for the Toyota-Folksam co-operation
• In-depth data collection started 1991 including crash recorder installation from 1992

Toyota – Folksam collaboration
• ECR is an integral part of a large accident data collection, includinginterior and exterior defformation measurements and evaluation ofinjury outcome.
• Data on traffic accidents and injuries comes from the police and the medical care services
• Folksam quarterly reporting to TME/TMC
• 10 000 recorder installation/year
• Capability to reproduce accidents
• Cooperation with retailers to remove ECR

Accident data collection result in:
• Accelerate the evaluation of new safety systems
• Advanced technologies are made available across the line up
• Models designed for better protection in real life accidents
• Deeper knowledge of the relation between impact severity and the risk of injury that help us to design a more crashworthy mobility
• Better understand factors influencing post-crash injury outcomes
