With this testing the group hoped to understand the difference between using power braking and coasting and what benefits each type will provide.
The graph above shows two separate runs using the same code to test power braking
The graph above shows two separate runs using the same code to test coasting
Average Braking Distance (meters) | Standard Deviation | Mean Power Usage (joules) | |
Power Braking | .4271 | 0.026304 | 37.562 |
Coasting | 2.0307 | 0.012261 | 30.1615 |
The table above helps display the difference between these two forms of testing. Power braking allows the AEV to brake much quicker then coasting, but requires an average of 7 joules more energy over the course of the run.
Our team will be using power braking moving forward. Even though this method requires more power it stops the AEV substantially faster than coasting, which is more important to the team.
