Toyota's new pre-crash technology directs steering

Toyota is developing a safety technology that takes control of the steering so the vehicle can veer away when it isn't able to stop before impact.

Toyota Motor Corp. showed some of its up and coming safety innovations in a demonstration to reporters Thursday at its facility in this town, west of Tokyo, near Mount Fuji.

All the world's are working on special safety technology in an effort to woo customers, as competition intensifies among manufacturers already neck-and-neck in delivering the regular features for their products.

Cars that stop or slow down automatically before an object or person in anticipation of a possible crash are not new. But Toyota's latest pre-collision system adds a steering-control feature.

In the new system, Toyota uses cameras and a super sensitive radar called "millimeter-wave," both installed in the front of the vehicle, to detect possible crashes such as a pedestrian crossing the road.

The vehicle calculates how braking and steering must be applied to avoid a crash, said chief safety technology officer Moritaka Yoshida.

"We must learn from accidents and keep making improvements in ," he said.

The Japanese automaker declined to say when the feature may be offered on a commercial model, or in which markets, but officials hinted it was ready to be offered soon.

Toyota said it was aiming for zero fatalities and injuries, although it did not say when that goal would be achieved.

Fatalities have been declining in auto accidents, because of better safety features, but deaths among in have not gone down in Japan.

Protecting pedestrians is increasingly key, according to Toyota, which makes the hybrid and Lexus luxury models.

Toyota showed what is called a pop-up hood, which rises slightly in a crash, to mitigate the impact of a pedestrian getting hit by a car, similar to features offered by European makers.

It also showed how parts of the rays from high-beam headlights could be blocked so that drivers could still see clearly what was ahead while headlights would appear to be on low beam to the driver in a car coming from the other direction.

Toyota also showed a steering wheel in development that measures the heartbeat of the driver to prevent crashes that can happen when drivers suffer heart attacks.

If they add steering control to their vehicles, I hope they include a way to turn it off. I like Toyota, but I don't want my car steering itself.

What could possibly go wrong!?

Precisely.

I'm also wondering if the manufacturer is planning to accept responsibility for injuries which can be shown to be the result of their self steering technology. I hope Toyota thinks about that. It might not be an issue in Japan, but it certainly will be in the U.S.

Cameras & Radar.. both installed in the front of the vehicle, to detect possible crashes
Veering to one side may crash into other cars, telephone poles, or fly off cliffs.

But doing nothing will cause an accident!

And humans neurons are too slow to react. I am sure Toyota did some research and know very well the behavior of their drivers. The car reacts faster than humans. Just bear it.

finitesolutions,

There are pending accidents/accidents where avoidance is not possible or avoidance of the primary accident may result in a secondary accident which may be worse than the primary accident.

When an accident cannot be avoided, a careful driver may be able to guide his vehicle in such a manner as to minimize injury/death. The driver cannot do this is the steering is taken out of his control.

I worry about foolishness like this. There are already cars on the road with no direct linkage between the steering wheel and the wheels. Electronic failure could leave the driver with an inability to drive. The proposal in this article is really scary.

The main cause of accidents is human drivers and not physical failures. So if yes some new type of accidents are introduced but a large part are solved it is worth-ed. 0 accidents will be nice and can happen with an all automatic transport system.
I am sure all car manufacturers are studying current exiting accidents in which their vehicles have been involved and are developing new technology based on it. ABS, airbag, belts have all been introduced to improve safety of the vehicle and occupants.

@Magnette: Seems to me you're somewhat of a special case...being an experienced race car driver you surely have a much keener sense of driving than most so for you it may not be totally necessary. However I know that for me anyway there have been situations where it's exactly that: 'I'm going to have an accident what should I do?' scenario. I have never crashed but I know that sometimes it's been pure luck because all my brain could compute was "oh shit"...and I'd the majority are the same.

If the sensor technology is comprehensive enough and the processor speed fast enough this could effectively rule out the pobbibility of a crash occuring...that is: as much as steering can be effective in avoiding a crash.

BenjaminButton,

Let me discuss a real accident I was involved in some years ago as an illustration of why an automated system may cause injury/death.

I was in a town with a four lane plus turning lane main street. As I was driving down the outside lane, a car with four teenage girls was passing me in the middle lane when the driver saw someone in the parking lot of a car dealership. The driver immediately turned right in front of me (certainly did not even see me). I could not avoid hitting the car. There was not enough distance between us to steer out of the accident nor was there enough time to stop. I was about to hit the front door passenger side which would have caused injury or death to the occupant. I managed to steer into the area between the front and back seats. This caused considerable damage to the car (and mine) but no one was injured in either car.

An automated system which would try to steer away from the accident would have killed/injured the passenger in that car.

You are just a troll.

Why don't you occasionally try to participate in a positive way to the discussion?

@Magnette

Look up the Dunning-Kruger effect. You are foolish if you think you can react faster than a computer.

Racing cars doesn't give you the Flash's reflexes.

I barely escaped that singularity of irony.

The "oh shit" maneuver saved me once. Took a turn too fast and the car went 180. "Oh shit" and I took my hands off the wheel because I accepted I was going to crash and didn't want to get my shoulders dislocated from locking onto the wheel. The car whipped itself back around on its own and I ended up stopping virtually bumper to bumper with a car in the opposing lane.

Gave him a wave, put it in reverse, got back in my lane, and drove off. I drive much more carefully now.

Wouldn't it be simpler to just watch where we are going with due diligence like the last generation did?

What an asinine comment, Burnerjack.

Back in the day I walked 20 miles to school up hill BOTH WAYS and all I had to scrub my balls were Brillo pads!

I once came across a stag at night on a bend of a country road at about 50mph and on my side of the road. I knew that a car was coming fast on the opposite side, but only because I had seen headlamps playing along the hedgerows. The small bank below the hedgerow was firm and dry looking. I left the road and mounted the bank briefly to avoid the animal rather than to stay on the road and cut across the apex of the bend. In doing so I avoided both the animal and a collision (possibly head on) - just a few scratches to the paintwork from the hedgerow. I'm not using this example to say we should never try to have automated systems, but it isn't all just city driving, and you don't have time to turn it off if the situation doesn't fit. I can't see how an automated system could have coped (worse interfered) in my situation, and I suspect it would have put me in the path of the unseen car.

Existing auto-brake systems are only active at lower speeds, it is likely this would be the same?
