Bug Description
On lines 505-524 of the compute_accel function in f110_simulator/node/simulator.cpp file, the if statement incorrectly deals with the case for when velocity is 0 m/s.
Line 514 should be:
} else if (state.velocity < 0)
The code below should be inserted between 523 and 524
else {
// accelerate
double kp = 2.0 * max_accel / max_speed;
set_accel(kp * dif);
}
Expected behavior
If the car is at rest (0 m/s) and is commanded the desired velocity is 2 m/s, the expected acceleration would be 4.29 m/s^2. However, currently it would accelerate at the force that the brakes are supposed to decelerate the car (max_decel which is 8.26 m/s^2 from the params.yaml file).
