摘要： A travel assistance method causes a sensor to detect a lane boundary present around a vehicle, calculates own positions of the vehicle, converts a coordinate system of the detected lane boundary into a coordinate system equivalent to map data stored in in accordance with the own positions, and integrates configuration information on the lane boundary included in the map data with the lane boundary of which the coordinate system is converted to generate integrated data, wherein an integrated range is determined, when the configuration information is integrated with the lane boundary of which the coordinate system is converted, such that the lane boundary includes at least either parts having different curvatures or straight parts directed in different directions, and the configuration information is mapped with the lane boundary of which the coordinate system is converted to generate the integrated data while including at least the determined integrated range.

摘要： Disclosed is a method for calculating a control setpoint of a hybrid powertrain of a motor vehicle, the hybrid powertrain including an electric motor and an internal combustion engine (ICE) that is equipped with a gearbox and that is supplied with fuel. The method includes: acquiring a value relative to a power requested at the vehicle's drive wheels; and determining the contribution of the electric motor and the ICE in order to satisfy the request for power at the drive wheels. The determination step involves calculating a triplet of three values, one value relating to the electromechanical power that the electric motor must provide, one value relating to the thermomechanical power that the ICE must provide and one value relating to the ratio that needs to be engaged in the gearbox, this triplet minimising the fuel consumption of the ICE and the current consumption of the electric motor.

摘要： 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.

摘要： A vehicle travel assistance method executed by a processor comprises: setting a travel lane in which a subject vehicle travels based on detection information of a sensor equipped in the subject vehicle, identifying a preceding vehicle traveling ahead of a subject vehicle based on detection information of a sensor, calculating, based on the detection information, a first evaluation value indicating a possibility that the subject vehicle can return to the travel lane from an adjacent lane adjacent to the travel lane after overtaking the preceding vehicle, calculating a shortening width of travel time shortened by overtaking the preceding vehicle based on the vehicle speed of the subject vehicle and the vehicle speed of the preceding vehicle, and determining whether or not to overtake the preceding vehicle based on the first evaluation value and the shortening width.

摘要： A method is for installing a geometric reference marker on a substantially flat horizontal ground for calibration of electrical and/or electronic components of a motor vehicle. The installation method includes positioning the vehicle on the ground with wheels of the vehicle parallel to a longitudinal axis of the vehicle and positioning geometric referencing equipment on the ground around the vehicle. The referencing equipment includes a set of distinct elongate plates forming rulers. Each ruler has a planar bottom face resting at least partially on the ground and being sufficiently rigid not to be deformed in a plane of the bottom face. The positioning is performed by placing the rulers of the adjustment equipment on the ground according to a predetermined pattern, at a predetermined distance from the vehicle.

摘要： A boarding-alighting position determination method determines a boarding position and an alighting position in a vehicle dispatch system that dispatches a vehicle in response to a vehicle dispatch request. A plurality of boarding position candidates and a plurality of alighting position candidates are calculated around a geographical point from which the vehicle dispatch request was transmitted. A vehicle position is detected when the vehicle dispatch request was transmitted. For each boarding position candidate, a travel route is calculated from the vehicle position at a time of the vehicle dispatch request to at least one of the alighting position candidates via the boarding position candidate. A travel time is calculated for the vehicle to travel the travel route calculated for each of the boarding position candidates. A selected boarding position is determined from among the boarding position candidates based on the traveling time for each boarding position candidate.

The scenario-specific operational control evaluation module instance includes an instance of a scenario-specific operational control evaluation model of a distinct vehicle operational scenario. Operating the scenario-specific operational control evaluation module instance includes identifying a multi-objective policy for the scenario-specific operational control evaluation model. The multi-objective policy may include a relationship between at least two objectives. Traversing the vehicle transportation network includes receiving a candidate vehicle control action associated with each of the at least two objectives. Traversing the vehicle transportation network includes selecting a vehicle control action based on a buffer value. Traversing the vehicle transportation network includes traversing a portion of the vehicle transportation network in accordance with the selected vehicle control action.
