  • Publication number: 20220135022
    Abstract: In a parking assistance device, a target parking position calculation unit calculates a target parking position of a subject vehicle based on a position of a corner point of a parking space. A constraint condition setting unit sets a constraint condition regarding a target parking route for guiding the subject vehicle to the target parking position based on a position and a posture angle of the subject vehicle, peripheral information of the subject vehicle, and the position of the corner point of the parking space. The constraint condition includes a condition that a curvature change rate of the target parking route is continuous. A target parking route calculation unit calculates the target parking route based on the position and the posture angle of the subject vehicle, the position of the corner point of the parking space, the target parking position, and the constraint condition.

  • Patent number: 9758145
    Abstract: A vehicle energy management device includes: an energy consumption related information acquisition unit which acquires energy consumption related information that is information related to energy consumption of an own vehicle in each of traveling sections; an energy consumption related information correction unit which corrects the energy consumption related information; and a control plan production unit which produces a control plan for vehicle instruments based on an estimated value of an energy consumption amount of each of the vehicle instruments calculated by using the corrected energy consumption related information. The energy consumption related information correction unit corrects the energy consumption related information based on a result of comparing an actually measured value of traveling characteristics of the own vehicle in each of the road categories and a statistical result of traveling characteristics of a plurality of general vehicles in each of the traveling sections.

  • Patent number: 9701302
    Abstract: In a vehicle energy management device, a travel route calculator calculates a travel route of a vehicle, and an energy consumption-related information obtaining unit obtains energy consumption-related information along the travel route. An energy consumption amount computing unit calculates, based on the energy consumption-related information, an estimated value of an energy consumption amount by vehicle devices (required travel energy amount) when the vehicle travels along the travel route. A control plan preparing unit prepares a control plan for the vehicle devices based on the required travel energy amount. A feedback control unit performs feedback control of the vehicle devices to reduce a difference between the estimated value and an actual measured value of the energy consumption amount by the vehicle devices.
