    摘要: A method controls a boost converter having N switching cells using synchronous pulse width modulation, in which N is a natural integer that does not equal zero. The method includes: measuring input voltages and output voltages of the boost converter; determining an output vector to define a representation of a linear state of the boost converter; calculating the variation in power of the electrical load; determining the N duty factors as a function of the second derivative of the output vector, the derivative of the power of the electrical load, and the ratio between the input voltage and the output voltage that have been measured; and controlling each switching cell of the converter depending on the duty factor that has been determined.

    摘要: Upon autonomous travel control of a subject vehicle having an autonomous travel control function based on a remote operation command from a remote operation device located outside the subject vehicle, when start of a remote operation by the remote operation device is input, a predetermined authentication code stored in the subject vehicle is displayed inside or outside the vehicle so as to be visible, the displayed authentication code is acquired by the remote operation device, a determination is made whether or not the authentication code acquired by the remote operation device matches the authentication code stored in the vehicle, and upon matching, a paring process between the vehicle and the remote operation device is completed.

    摘要: A method performs autonomous travel control of a subject vehicle to a target stop position on the basis of a remote operation command from a remote operation device. The subject vehicle has an autonomous travel control function and an automatic locking/unlocking function for a vehicle door. The autonomous travel control is executed under a precondition that a locking/unlocking device for the door is unlocked. The method includes prohibiting the automatic locking/unlocking function from locking the door while the vehicle is executing autonomous travel control; detecting a distance between the vehicle and the remote operation device when the vehicle stops at the target stop; setting a temporal interval from when the vehicle stops until the locking/unlocking device for the door is locked using the automatic locking/unlocking function to a temporal interval in accordance with the distance; and locking the door using the automatic locking/unlocking function when the temporal interval has elapsed.

    摘要: A method for controlling a level of charge of a traction battery of an electric vehicle connected to an electricity distribution grid by way of a charger during a downtime phase of the vehicle. The method includes a first step of forcibly discharging the battery, performed in a discharging circuit associated with the battery, with a discharge current that is calibrated in terms of strength with respect to the nominal capacity of the battery, so as to slowly and completely discharge the battery to its minimum voltage, and a step of normally charging the battery with a setpoint charging current prescribed by the charger or the battery, so as to charge the battery to a useful level of charge of the battery.

    摘要: A road detection method for a motor vehicle provided with at least one rotary multilayer LIDAR sensor and at least one data processor includes acquiring LIDAR data of the environment of the vehicle. The data for which the angle of the beam with respect to the plane of the vehicle is greater than or equal to zero are eliminated from the acquired LIDAR data. For each LIDAR datum, theoretical coordinates of a point are determined as a function of the angle of the beam with respect to the plane of the vehicle and of the angle of the beam in the plane of the vehicle. The standard deviation between the theoretical coordinates and the coordinates of the LIDAR datum is determined. Then, it is determined that the LIDAR datum forms part of the road if the standard deviation is lower than a predefined threshold.
