You are allowed to monitor a driverless vehicle during any event.
Every member of the team that is in the dynamic area must wear the dynamic vest at all times.
4) An AC current source is connected to a heating element (resistor). However, it is measured that the power cables have an inductance of 0.01H. Choose the capacity of the capacitor to be connected in series in order to maximize power transfer to the heating element. The AC power source operates at a frequency of 5/π Hz.

0.01 uF
5) Choose the correct answer from below:
A Lidar mounted on top of the front bulkhead can protrude from the surface envelope.
A red indicator light in the cockpit that is easily visible even in bright sunlight and clearly marked with the lettering “EBS” must light up If the EBS detects a failure.
The response value of the IMD must be set to >= 250 Ω/V, related to the maximum TS voltage.
The TSMP current limiting resistor for a 365V maximum TS voltage is 15 kΩ.

6 6
9 3
9 6
8) Choose the correct answer from below:
In the Manual driving mission the EBS must be armed.
A steel plate in the front wishbone of a rear only driven car must have a resistance bellow 5 Ω to LVS ground.
In a PCB that contains both TS and LVS parts, with a TS voltage of 287 volts, the minimal cut width to be made in the PCB in order to be rules compliant is 6.4mm.
Manual steering should not be possible with mission selected and ASMS on.
9) Choose the correct answer from below:
The IA assembly can be attached to the AIP by four 8mm metric grade 8.8 bolts.
The minimum overlap when using multiple panels to form the firewall is 10mm.
In an EV, the quick jack must have attached to it two pairs of high voltage insulating gloves and a multimeter with two 4mm banana plug test leads rated for 1000V CAT III or better.
You are not allowed to place video/photographic cameras on a formula student vehicle.
10) Choose the correct answer from below:
The RES can close the SDC after it has been opened mid-run without additional action on the vehicle.
A Driverless Vehicle must be capable of producing 2 different sounds.
He vehicle can directly transition from the AS Finished state to the AS ready state for the next run.
Any signal of the AS is not a SCS.
11) Choose the correct answer from below:
In the SDC, the LVMS comes after the TSMS.
Required measuring points are “TS+”, “TS-” where “TS+” and “TS-” indicate tractive system measuring points.
The temperature rating for TS wiring can be at least 90 degrees Celcius.
The driver can reset an open SDC that was opened by the IMD.
12) The camera on a FS Driverless Vehicle outputs an image of 2048x2048 pixels. This image gets downscaled by a factor of 4 and then passes through 2 convolutional layers in series, with 3x3 convolution filters each. Calculate the size of the output feature map axb. Choose the answer in the format a b, assume no padding in convolutional layers:
514 514
512 512
510 510
508 508
13) Choose the correct answer from below:
The EBS test can be conducted before the rain test.
During the brake test, the TS is switched off before the vehicle stops moving.
After any dynamic event, if the officials wish to check the vehicle’s compliance with rules, the vehicle does not have to be able to enter ready-to-drive mode in order for the team to remain in the competition.
In the rain test the vehicle must be in ready-to-drive mode.
14) A completely rectangular EV Formula student vehicle has given volume V = 2.35 m3, length l = 2.35m, height h = 800mm. It is set to do a test acceleration run in a sufficiently large straight line. The Tractive System provides the vehicle with a constant acceleration force FTS = 2400N. Given that air density is ϝ = 1.225 kg/m3, the drag coefficient of the vehicle is CD = 25.07, and ignoring rolling resistance, choose the vehicle’s final speed in km/h, rounded to the closest integer.
45 km/h
55 km/h
40 km/h
26 km/h
15) A team wants to register for the FS East competition 2022. However, due to COVID-19, your deadlines have not been met concerning the documents you have to upload in order to register for the competition. Your ASF was submitted 3 days and 4 hours after the competition deadline. Afterwards, the officials requested a correction for it, the team uploaded the correct document 8 days and 12 hours after the request. Furthermore, the VSV was submitted 5 days and 8 hours after the competition deadline. Choose the total penalty points for the team due to delayed submissions.
