| IMD and Tractive System Status Indicator |
IMD must open shutdown circuit in 30 seconds when isolation fault is present. 1. Activate Tractive System. IMD indicator off, TSSI is green 2. Connent IMD test box between TSMP and GLVS Ground. 3. IMD must trip in 30 seconds and TS voltage must decrease below 60VDC is 5 sec. IMD Indicator is on (red). TSSI is flashing red. 4. Remove IMD test fault and wait 30 seconds. TS stays off, IMD indicator stays on, TSSI stays flashing red. |
Test HV+, Test HV- |
| master switches, shutdown buttons and brake-over-travel-switch and interlocks |
All switches on --> TS Master switch off. All switches on --> GLV Master switch off. All switches on --> left shutdown button off. All switches on --> right shutdown button off. All switches on --> Cockpit shutdown button off. All switches on --> brake-over-travel-switch off. All switches on --> Open Interlock(s) of outboard wheel motor (if applicable) |
TS voltage must decrease below 60VDC in 5 sec. Allow team to set pace of tests to prevent overheating precharge / discharge resistors. |
| Inertia switch |
Unmount inertia switch. Activate TS and measure HV voltage. Shake the switch and check if TS is shutdown. |
TS voltage must decrease below 60VDC in 5 sec |
| Ready To Move Light |
The RTML must be flashing amber when GLV turned on and the voltage outside of accumulator container exceeds 60V DC. |
Visible check |
| Ready-To-Drive Mode |
The RTML must comply with DOT FMVSS 108. Visible check Ready-To-Drive Mode Additional actions are required to set the car to ready-to-drive mode 1. Enable TS. 2. Press Accelerator, motors SHOULD NOT spin. 3. Press brake and start button. 4. Press Accelerator, motors SHOULD spin. 5. Press shutdown button. 6. Release shutdown button and enable TS. 7. Press Accelerator, motors SHOULD NOT spin. 8. Press brake and start button. 9. Press Accelerator, motors SHOULD spin |
The team must demonstrate how the car is set to Ready-To-Drive mode by the driver (pressing the brake pedal is mandatory) |
| Ready-To-Drive-Sound Test |
The car must make a characteristic sound, once but not continuous, for at least 1 second and a maximum of 3 seconds when it is ready to drive. The sound level must be a minimum of 80dBA, fast weighting, in a radius of 2m around the car. The used sound must be easily recognizable. |
Check for Ready-To-Drive sound when team starts vehicle |
| Brake Light |
Press brake pedal |
Check for sufficient brightness for visible activation in bright sunlight |
| APPS / Brake Pedal Plausibility Check |
Torque production must stop when accelerator and brake pedal are pressed simultaneously: 1. Press accelerator to show that axle turns. 2. With accelerator > 25%, press brake pedal. Axle must stop. 3. Keeping accelerator >25%, release brake pedal. Axle must remain stopped. 4. Slowly release accelerator, axle may turn again once < 5% pedal position |
Team demostration per procedure |
| APPS Implausibility Check |
Torque production must stop if APPS are implausible. 1. Press accelerator to show that axle turns. 2. Unplug all but 1 APPS. 3. Press accelerator, axle must not turn. Repeat for each APPS sensor |
Team demostration per procedure |
| Brake System Plausibility Device |
1. Enable TS. 2. Press and hold Brake (may require driver in car). 3. Turn up simulated current (5kW at nominal voltage). 4. TS must shut off in 0.5 sec. 5. Release brake and turn off simulated current. The TS may not automatically return to active state. The driver must not be able to reactive the tractive-system. |
