Give Us A Brake

Oh, Just Stop It

Autonomous Emergency Braking

There’s plenty of `white noise’ floating around right now about autonomous emergency braking  (AEB) being compulsory in cars soon.

Some motoring groups are lobbying for AEB to be mandatory in order for a new car to score a 5-star crash rating from ANCAP (Australian New Car Assessment Program).

The concept of a car taking pre-emptive action to prevent an imminent crash has plenty of appeal particularly with the mobile phone effect causing mayhem on our roads.

AEB would theoretically prevent someone texting and not looking at the road from having a collision. Good and bad as it would promote bad behaviour and bad driving.

But there are other issues surrounding AEB that still haven’t been addressed and it concerns how the system works in the real world.

 

Scenario 1

We are driving in a Honda CRV with AEB on a three lane highway attempting to go between two trucks occupying the two outside lanes. When the CRV gets between the trucks it sees a crash situation and locks up the brakes in emergency stop mode.

Lucky nobody was behind.

 

Scenario 2

We are in a Mazda 6 with AEB approaching a toll both boom gate at about 30kmh. The Etag beeps and we keep rolling perhaps a tad too quickly for the boom gate which starts to rise just as the AEB goes into full crash stop mode even though the gate is now up.

 

Scenario 3

We are in a Mitsubishi Outlander with AEB and want to move quickly from one lane to another but the AEB thinks we cut too close to the car in front as we change lanes and applies full crash stop mode just as we clear the other car.

Oops.

Point is, we aren’t there yet with AEB technology, close but the system still needs some ironing out.

Then there’s the cost. Bust a windscreen in a Subaru with `Eyesight’, the system driving AEB, and you’ll see what I mean.

AEB needs a touch more refining.
