Automatic car rolling back on hills

muffinek

I am fairly new driver. I drive semi automatic Auris 07 and ongoing issue I have it keep rolls back on any hill even if it is not very steep. 

I try to shift my foot v quickly from brake to accelerator but the car still rolls back a bit. How to avoid it? 

I read online that apparently I should apply a hand brake press gently accelerator and then release the hand brake. Unfortunately I can't do that as my hand brake is pretty stiff and it is impossible to make a smooth transition. 

Is there anything else I could?

I forgot to add I took the car to the garage and they had a look at the handbrake and apparently there isn't anything they can do about it. It is just an old car.

The handbrake should work whether the car is old or not - it is a requirement of the MOT.

As you have two pedals to operate and two feet in the vicinity, why not hold the car on the brakes with your left foot and manage the throttle with your right? If you pay attention you should be able to gauge the release point after the first two or three tries. 

Clearly fixing the h/brake is the best solution, but pragmatism often wins out.

Seriously? I hope I’m not in a queue with you behind me on a hill…;)

I have a 2016 auto, on a hill it hold for 20-30 seconds and then drops its revs and would roll backwards.
As above just stop as normal and switch feet over so left foot is on the brake. 

Your hand brake should hold the car, if not that’s a bigger issue in my opinion.

Seriously? Yes. Using the brake in that context is easy. Have you never used your left foot for anything other than pressing the clutch? Honest John when he was in The Telegraph often suggested drivers of automatics should learn to use both feet instead of just one for both pedals, and left foot braking is a common technique that takes very little practice for it to become as natural as the right foot.

In this context there’s no risk at all. As the driver feels drive being taken up and the car starting to move forwards, release the brake. The rolling backwards issue has been taken care of and our driver here can then brake in the usual way with the right. Can’t see your issue tbh.

What would be the problem ?

This is a common problem for the MMT (multi mode transmission) and a lot of other automated manual gearbox cars (often called semi automatics).

They just don't "creep" like torque converter, CVT and dual clutch autos, so they tend to roll back when you move your right foot off the brake to the accelerator as they just won't transmit any torque to the wheels until you apply the accelerator.

Other types of automatics do transmit some torque to the wheels even on idle which you hold back with the foot brake as the lights, on hills etc.

New cars with this sort of automated manual gearbox tend to come with auto hill hold or auto electric handbrakes as standard, this holds the car until some torque is transferred to the driven wheels, unfortunately yours is an earlier car without it.

Because of this various people, like Honest John suggest driving these types of cars "two footed".
So on a hill, stop as normal, swap your right foot on the brake with your left so you right foot is now free for the accelerator.

You can of course use the handbrake, just as you would with a manual car.
Stop and apply the handbrake, move your right foot over to the accelerator, when it's time to move off apply the accelerator while feeding off the handbrake slowly.

Clarkson came up with a novel approach to a similar problem, but that involved towing a larger log around behind the car which jammed the back wheels to stop it rolling back! Not very practical though.

So it's learn one of the more sensible techniques or perhaps swap your car for an auto that will "creep".
