IPSGA

Please could someone explain the difference between the speed phase, (when using it in relation to the accelerator) and the acceleration phase of the System of Car Control.

Re: IPSGA

When in the SPEED phase of the system, you should adjust your speed to the correct speed for the hazard/s.  That could mean braking, decelerating, maintaining or even increasing, each hazard should be continuously assessed and the correct speed should be achieved before reaching the hazard (ideally).

When in the ACCELERATION phase of the system, your speed for the hazard should already be correct and you are applying the throttle gently to maintain stability through the hazard and if safe legal and appropriate, to accelerate away from the hazard.

I hope this helps.

Re: IPSGA

Thanks Kev.

Just to clarify, if my speed is already appropriate for the hazard, would I then bypass the speed and gear phases and move straight into the acceleration phase?

Each phase is to be considered and acted upon if necessary - the information phase is considered constantly

Re: IPSGA

Having considered all phases you can enter the system at any point.

Not really, you wouldn't "Bypass" them.  As Rog pointed out, you would consider each and every phase, but often you will find that in some phases of the system, no adjustment is required at that time so you advance to the next phase of the system.

Always consider all phases in sequence and...consider returning to an earlier phase of the system when new information comes to light.
