Answer to Question #301159 in MatLAB for Mr Z

Question

Table 1: Driving styles associated with acceleration values

Driving style Economic (1) Normal (2) Aggressive (3)

Acceleration magnitude [m/s2 ] 0.7-2.3 2.31-3.30 3.31-8.5 

Create variable ds mapping to store corresponding classification values of 1,2 or 3, which represent different driving style as shown in Table 1. You need to evaluate only the magnitude the of the acceleration/deceleration.

    Table 1: Driving styles associated with acceleration values

A = [0.7, -2.3, 2.31, -3.30, 3.31, -8.5]


NORMAL = 2;
ECONOMIC = 5;
AGGRESSIVE=8;


for r=1:length(A)
    if(abs(A(r))<=NORMAL), 
        fprintf('\n\nDriving Style: Normal, Acceleration = %.2f m/s2',A(r));
    end
    if(abs(A(r))>NORMAL && abs(A(r))<=ECONOMIC), 
        fprintf('\n\nDriving Style: Economic, Acceleration = %.2f m/s2',A(r));
    end
    if(abs(A(r))>ECONOMIC), 
        fprintf('\n\nDriving Style: Agressive, Acceleration = %.2f m/s2',A(r));
    end
end
fprintf('\n\n');

Matlab utput:

A =

  0.7000  -2.3000  2.3100  -3.3000  3.3100  -8.5000

Driving Style: Normal, Acceleration = 0.70 m/s2

Driving Style: Economic, Acceleration = -2.30 m/s2

Driving Style: Economic, Acceleration = 2.31 m/s2

Driving Style: Economic, Acceleration = -3.30 m/s2

Driving Style: Economic, Acceleration = 3.31 m/s2

Driving Style: Agressive, Acceleration = -8.50 m/s2
