Hi Ben,
As per my understanding, you want to classify the driving system based on the acceleration and the mapping table shared and are facing issues while doing so.
You can achieve the same using the code below, where I'm populating the "ds_mapping" based on the mapping table and then creating a line plot with two different variables on both y-axes of the plot. Please not, as the actual acceleration array was not present, so I have created a random acceleration array.
a = -6.5;
b = 6.5;
timeInterval = 1800;
acceleration = a + (b-a) * rand(1,timeInterval);
ds_mapping = [];
for i=1:timeInterval
if(abs(acceleration(i))<0.7)
ds_mapping = [ds_mapping,0];
elseif(abs(acceleration(i))>=0.7 && abs(acceleration(i))<2.79)
ds_mapping = [ds_mapping,1];
elseif(abs(acceleration(i))>=2.79 && abs(acceleration(i))<3.64)
ds_mapping = [ds_mapping,2];
elseif(abs(acceleration(i))>=3.64)
ds_mapping = [ds_mapping,3];
end
end
figure;
hold on;
title("Acceleration and Driving Style classification");
xlabel("Time(s)");
yyaxis left;
plot(1:timeInterval,acceleration,"Color","blue");
ylabel("Acceleration(ms^2)");
ylim([-6.5 6.5]);
yyaxis right;
plot(1:timeInterval,ds_mapping,"Color","cyan");
ylabel("Driving Style");
ylim([0 3]);
hold off;
I hope it helps!
