% Calculate lateral forces
alpha_f = atan((vy + Lf * yaw_rate) / vx);
alpha_r = atan((vy – Lr * yaw_rate) / vx);
Fyf = -Cf * alpha_f;

dvy = (Fyf + Fyr) / m – vx * yaw_rate;
dyaw_rate = (Lf * Fyf – Lr * Fyr) / Iz;
vx = vx + dvx * dt;
vy = vy + dvy * dt;
yaw_rate = yaw_rate + dyaw_rate * dt;
yaw_angle = yaw_angle + yaw_rate * dt;
% Update positions
x = x + (vx * cos(yaw_angle) – vy * sin(yaw_angle)) * dt;
y = y + (vx * sin(yaw_angle) + vy * cos(yaw_angle)) * dt;
% Store results

v_u = v_u + a_u * dt;
z_s = z_s + v_s * dt;
z_u = z_u + v_u * dt;

% Speed error
error = desired_speed – speed;
% PID control
integral = integral + error * dt;
derivative = (error – prev_error) / dt;
control_signal = Kp * error + Ki * integral + Kd * derivative;
% Vehicle dynamics (simplified model)
acceleration = control_signal / m;
speed = speed + acceleration * dt;
% Store results
speed_arr(i) = speed;
acceleration_arr(i) = acceleration;
control_signal_arr(i) = control_signal;
