The System of Car Control
As used in Police Driver Training, Please read Roadcraft for the full story.
The Information stage of the system is paramount, however each individual will have a different perspective as to what they are seeing and how they process it.
The Information phase encompasses all other parts of the 'System'.
Positioning is an essential part of the system of car control that we use. We want to be in the best position to give us maximum visibility, so not only can we see as much of the road ahead as possible, but so other road users can see us earlier.
Safety should always be paramount.
The best road position is dependant on a lot of factors. Safety, Road layout, traffic, hazards, your speed, information e.g road signs. Do not give up Safety for position.
Adjust your speed as necessary. Use your accelerator or brake to give you the correct speed. Anticipation and acceleration sense are a key part of this.
We are told we must use the correct gear. What is the correct gear? The correct gear is the most responsive gear for the speed that you have chosen for the circumstances, that is one that will allow you to be able to accelerate or decelerate and give you control of the momentum of the car. This is most noticeable on a hill. By being in this gear you have maximum control allowing the use of acceleration sense. This applies to automatic gearboxes as well as manual.
Acceleration sense is about how you vary your foot pressure on the accelerator pedal
allowing you to anticipate the changing conditions ahead so that you are at the correct
speed to negotiate a hazard without braking. Acceleration sense is an art that needs
to be practised. (More about this in 'Acceleration')
The aim is to choose the correct gear for every circumstance Making the gear change smoothly Engaging the chosen gear without going through an intermediate gear first. Knowing the maximum road speed for each gear is essential, so if you are going from a high gear to a low one you do not cause any damage to the gearbox.
Acceleration:- Apply the correct degree of acceleration to negotiate the hazard
