Abstract: It is possible to cope with a deviation of a relative position between a headlight and an in-vehicle camera. An in-vehicle system includes: an irradiation unit that irradiates an area other than a set light-shielding range with light; an imaging unit that images a range including an irradiation range of the light emitted by the irradiation unit to acquire a captured image; an object detection unit that detects a non-target object which is not to be irradiated with the light from the captured image; a direct irradiation prevention unit that calculates the light-shielding range on the basis of a position of the non-target object in the captured image and correction information, and sets the light-shielding range in the irradiation unit; a correction-time light-shielding range setting unit that sets the predetermined light-shielding range in the irradiation unit; and a correction calculation unit that calculates the correction information on the basis of the captured image when the correction-time light-shielding range setting unit sets the light-shielding range in the irradiation unit.

Abstract: An object of the present invention is to provide a power conversion device capable of specifying a failure location of an inverter in detail when an attempt of active discharge fails. There are provided an arithmetic operation circuit 102 that outputs a discharge instruction to control a discharge operation based on a voltage between both ends of a discharge circuit, and an output circuit 203 that outputs a drive signal based on the control signal. The arithmetic operation circuit 102 monitors an amount of the decreased voltage between both the ends of the discharge circuit, an LV read back signal being an output of the arithmetic operation circuit 102, and an HV read back signal being an output of the output circuit 203, and specifies a failure location.

Abstract: An axial deviation of the sensor is corrected. An aiming device that calculates a correction parameter for correcting a detection result of a target sensor includes an estimated-track generation unit that detects a track of a target for a period when an own vehicle moves, by using information of a movement of the own vehicle, which is detected by a movement sensor, and generates a plurality of estimated tracks having different start-point positions from the detected track of the target by using a first variable group, a corrected-track generation unit that generates a plurality of corrected tracks from the track of the target around the own vehicle, which is detected by the target sensor, by using a second variable group, and a correction parameter calculation unit that selects a combination in which a difference between the estimated track and the corrected track is small, and calculates the correction parameter for correcting a displacement of the target sensor by using a first variable related to the selected estimated track and a second variable related to the selected corrected track.

Abstract: An object of the present invention is to provide a sensing performance evaluation and diagnosis system capable of detecting a failure sign of an external-environment recognition sensor as a diagnosis target without relying on reference information registered in advance on a map, by comparing an output of the external-environment recognition sensor as the diagnosis target with a reference output of the external-environment recognition sensor. The sensing performance evaluation and diagnosis system includes a sensing data acquisition unit that acquires sensing data around an own vehicle from an observation value of an external-environment sensor as a diagnosis target, which is mounted on the own vehicle, a surrounding information acquisition unit that acquires surrounding information data around the own vehicle from an observation value of a reference external-environment sensor, a reference value calculation unit that generates reference value data based on a recognition history of relative information to a reference object, which is included in the surrounding information data, and an evaluation unit that evaluates whether or not performance of the external-environment sensor as the diagnosis target is deteriorated or evaluates a degree of performance deterioration, by comparing the sensing data related to the reference object to a threshold value set for the reference value data.
