Getting the acceleration performance of a motorcycle

Is it possible to perform a simulation to get how much time it took for the motorcycle to reach 60 or 100 kph.

My goal is to compare the acceleration performance of the motorcycle with CVT compared to a motorcycle with AI controlled transmission.

    Hi @sudo,

    Simply use the Straight Line Acceleration (StrLinAcc) standard event from the Vehicle Tools Extension along with a Sensor entity. You can design the Sensor to Halt the simulation when the input expression, vehicle linear velocity, is at or above the desired speed. Simply compare simulation final times to evaluate the performance of both vehicles.

    Sensor Details:

    • The VARVAL expression uses the Vehicle Long Velocity solver variable under the Instrumentation system.
    • The velocity is converted from mm/s to kph (277.78)

    Hope this helps!
