Answer to Question #303079 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 ]

Economic (1)

0.7-2.3

Normal(2)

2.31-3.30

Aggressive(3)

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

ECONOMIC    = 1;
NORMAL      = 2;
AGGRESSIVE  = 3;


% Acceleration magnitude [m/s2] 0.7-2.3 2.31-3.30 3.31-8.5
Acc = [0.7, -2.3, 2.31, -3.30, 3.31, -8.5];
ds_mapping = [ECONOMIC,NORMAL,AGGRESSIVE];
for r=1:length(Acc)
    if(abs(Acc(r))<=2.3), 
        fprintf('\n\tAcceleration = %5.2f m/sec^2:\t Driving Style: ECONOMIC\tCLASS: %d',Acc(r),ds_mapping(1));
    end
    if(abs(Acc(r))>2.3 && Acc(r) <= 3.30), 
        fprintf('\n\tAcceleration = %5.2f m/sec^2:\t Driving Style: NORMAL:\t\tCLASS: %d',Acc(r),ds_mapping(2));
    end
    if(abs(Acc(r))>3.3),

    end
        
end
fprintf('\n\n');

Matlab Output:

Acceleration = 0.70 m/sec^2: Driving Style: ECONOMIC CLASS: 1

Acceleration = -2.30 m/sec^2: Driving Style: ECONOMIC CLASS: 1

Acceleration = 2.31 m/sec^2: Driving Style: NORMAL: CLASS: 2

Acceleration = -3.30 m/sec^2: Driving Style: NORMAL: CLASS: 2

Acceleration = 3.31 m/sec^2: Driving Style: AGGRESSIVE: CLASS: 3

Acceleration = -8.50 m/sec^2: Driving Style: NORMAL: CLASS: 2

Acceleration = -8.50 m/sec^2: Driving Style: AGGRESSIVE: CLASS: 3
