  • Publication number: 20230018073
    Abstract: A method for determining a speed profile to be followed by a vehicle, including acquiring event data including a distance from an event and a target speed at this event for the vehicle, and determining a speed profile to be followed as a function of time, between an initial speed and the target speed in three successive distinct phases, respectively a first phase in which the jerk is set constant at a predetermined maximum jerk value to reach an optimal target acceleration value, a second phase in which the optimal target acceleration value is kept constant, and a third phase in which the jerk is again set constant to reach a zero acceleration value at the end of the third phase. The optimal target acceleration value is such that the distance required to carry out the three phases of the profile is equal to the distance from the event.

  • Patent number: 11518257
    Abstract: A method for controlling the input voltage frequency of a DC-DC converter includes calculating a control frequency value of the DC-DC converter. If the measured voltage is greater than the upper voltage limit, the control frequency corresponds to the minimum control frequency. If the measured voltage is less than the lower voltage limit, the control frequency corresponds to the maximum control frequency. If the measured voltage is between the upper voltage limit and the lower voltage limit, the control frequency corresponds to an average frequency calculated as a function of the difference between the setpoint voltage value and the measured voltage, upper error values and lower error values, and maximum and minimum control frequency values.
