Introduce TimeInUse signal for ElectricMotor

[JonathanForce]

Description

It would be interesting to know the engine hours for electric motor.

Looks good to me, will bring it up on the VSS meeting today. You need to add a sign-off to the commit, for example with git commit -s --amend and then a force push

Thank you @erikbosch

MoM:

• Adnan: Possible remove the term engine, call it "motor hours", "active hours", "running hours", "hours in use"
• Possibly "Time in use"
• Adnan: Do use EV use rotation as criteria?
• Erik: When do we want to increase timer, only when motor rotating, or rather some status ("ready")
• Please review

MoM:

• Jonathon: For us READY state is that if gas pedal is pressed vehicle will move. But definition can vary
• Daniel: Unclear from when it is measured
• J: Total time in use
• Erik: Shall Park be considered READY?
• Nick: In my vauxhall when moved out of Park
• S: Also charging is part of vehicle lifetime
• Please continue review/discuss, lets continue discussion on next meeting

Let's start from the beginning.

What we want: For electric vehicles, we want to determine a degree of wear on parts based on how long the vehicle has been in use.

What is the trigger: We want this time to increase as soon as the vehicle is ON and the transmission is not in the 'Park' position. So, the condition is 'Transmission.SelectedGear' is not '126=Park’.

A question was about the charging time. If you want this signal to remove an ambiguity, we can add a ‘TimeInCharge’ signal based on the ‘Charging.IsCharging’ signal.

MoM:

• Stefan: Terminal50 (Klemme 50) could be used - if you turn key you have ACC on first step, then ON, think it is standard. Also others exist like Terminal30 (permanent).
• Erik: Partially different criteria compared to using gear!=park
• Stefan: Also electrical components degrade, not only motor
• Pierre: What is use case?
• Jonathan: Do not want to increment timer if just listening at radio
• J: At BRP we use hydrofoils and other non-standard vehicle types
• S: You want to know when high voltage connection is closed/engaged.
• E: Do not know how EV handle if it is "Park" for a long while, does it turn off (disengage) the EV-drive.
• E: An alternative would be to have it less general, like "READY" in a previous commit version
• P: Would be fine to leave it to OEM decide.
• P: But could good to be document why it useful:
• E: AP Jonathan; Change to "READY", add rationale for why signal is useful as comment
• J: That was my first proposal, but comment for current solution last week
• J: I can update but I will not participate in meetings onward
• E: AP Jonathan to update
• Merge discussion next week
