Date Range In Power Bi between Start / end date with working hours

Hi there,

I want to create a Heat Matrix that shows you the active users/vehicles that are out and about based on their working hours - So if one vehicle is out from 1am - 5am on a monday it should show as 
       Mon

1am    1

2am    1

3am     1

4am     1

5am     1

however if 2 vehicles are out from 1am to 5am on a monday it should show as 2 and so on

        mon

1am    2

2am    2

3am     2

4am     2

5am     2

Currently my data is Australia Time Start UTC+10Australia Time End UTC+10

also right next to these columns is a Vehicle Column.

My end goal is to produce something like this --- which is the total working hours per vehicle

Thank you for helping
