Abstract: An evaluation device includes a set temperature evaluation portion, an ecological driving evaluation portion, and a notification portion. The set temperature evaluation portion determines a set temperature evaluation value based on a set temperature that is a target temperature. The ecological driving evaluation portion is configured to determine an ecological driving evaluation value based on at least the set temperature evaluation value. The notification portion is configured to notify the occupant of the ecological driving evaluation value. The level of power saving rises with change of the set temperature evaluation value or the ecological driving evaluation value. When the set temperature is changed, and the change of the set temperature causes increase of the level of power saving without decrease in power consumption of the vehicular air conditioner, the set temperature evaluation portion changes the set temperature evaluation value in the one of positive and negative directions.

Abstract: In a MG control device, a standard voltage calculation part calculates a d axis standard voltage and a q axis standard voltage in a standard state in which no demagnetization occurs in permanent magnets of a MG. A magnetic flux change amount estimation value calculation part calculates a basic magnetic flux change amount estimation value based on a deviation of a specific value from the q-axis standard voltage. This specific value is obtained by multiplying q axis real voltage with a ratio of the d axis standard voltage and the d axis real voltage. A magnetic flux change amount estimation value correction part adjusts a magnetic flux change amount estimation value by correcting the basic magnetic flux change amount estimation value relatively to a detection threshold value based on characteristic change of the MG in a demagnetization state of the permanent magnets of the MG.

Abstract: In a MG control device, a standard voltage calculation part calculates a d-axis standard voltage Vd_std and a q-axis standard voltage Vq_std to be supplied to a MG. A first magnetic flux change amount estimation value calculation part calculates a first magnetic flux change amount estimation value Δϕ1 based on a deviation of a specific value from the q axis standard voltage Vq_std, where the specific value is obtained by multiplying a ratio (Vd_std/Vd_real) with a q-axis real voltage Vq_real, where Vd_real represents a d-axis real voltage. A second magnetic flux change amount estimation value calculation part calculates a second magnetic flux change amount estimation value Δϕ2 based on a deviation of the q-axis real voltage Vq_real from the q-axis standard voltage Vq_std. The calculation switching part selects one of Δϕ1 and Δϕ2 based on an operation state of the MG.

Abstract: In an object recognition apparatus, a range point acquirer irradiates each of irradiation areas arranged in a horizontally and vertically extending grid and forming a detection area for detecting a target with laser light and receives the reflected light from the respective irradiation areas, thereby acquiring a plurality of range points representing per-irradiation area coordinates of the target. A noise remover is configured to, based on either or both of degrees of angle proximity and degrees of distance proximity between a plurality of subject range points to be determined whether to be a noise point, of the plurality of range points, as viewed from a reference point, determine whether or not each of the subject range points is a noise point, and remove the noise point from the plurality of range points. An object recognizer uses the plurality of range points other than the noise points to recognize the object.
