Constructor Detail

DecelerationProfile

public DecelerationProfile(double maxSpeed)

create a new acceleration / deceleration profile

Parameters:

maxSpeed -

Method Detail

setDecelerationFromSpeed

public void setDecelerationFromSpeed(double speed,
                                     double accdec)

Set the acceleration / deceleration for current speed HIGHER than speed. Add the points in increasing speed. Sorting is not (yet) done automatically.

Parameters:

speed - the speed above which accdec is used

accdec - the acceleration (positive) or deceleration (negative)

getDeceleration

public double getDeceleration(double speed)

Gets the acceleration / deceleration for a given speed

Parameters:

speed -

Returns:

initializeProfile

public void initializeProfile()

getBrakeTime

public double getBrakeTime(double initialSpeed,
                           double endSpeed)

Parameters:

initialSpeed -

endSpeed -

Returns:

the time to brake from the initialSpeed to the endSpeed

getBrakeDistance

public double getBrakeDistance(double initialSpeed,
                               double endSpeed)

Parameters:

initialSpeed -

endSpeed -

Returns:

the distance to brake from the initialSpeed to the endSpeed

main

public static void main(java.lang.String[] args)

Parameters:

args -
