A vehicle diagnosis system is configured to instruct vehicle operations required to finish a diagnosis without any increase in the storage capacity of an on-vehicle electronic control unit. When a repair person requests results of a self-diagnosis of a vehicle executed by an ECU using a diagnosis terminal, a management server acquires instruction texts for the vehicle operations required to finish the diagnosis from a by-type diagnosis process database at a remote management station and causes the diagnosis terminal to display the texts. The repair person operates the vehicle according to the instruction texts displayed on the diagnosis terminal to finish the self-diagnosis for which the request for diagnosis results has been made.

An electronic control apparatus includes a control circuit and has a power supply holding function whereby when a power switch-off command is received by the apparatus, the supplying of power to the control circuit is continued until it has completed specific processing, during a power supply holding interval. The duration of each such interval is measured and stored in non-volatile memory, and subsequently used for detecting any power supply holding function abnormality, and for ensuring that the specific processing is actually performed, and distinguishing between an abnormality causing premature switch-off and an abnormality causing failure to terminate the supplying of power.

An electric vehicle includes a vehicle body frame; an electric motor; a swing arm pivotally supporting a rear wheel at a rear end thereof; a drive shaft for transmitting the driving force of the electric motor to the wheel; and a suspension connecting the vehicle body frame and the swing arm together. The electric motor is set in a longitudinal layout in which a rotating drive shaft is disposed in a front-rear direction of the vehicle; and is offset from a center to either of left and right sides in a vehicle width direction. The suspension is disposed under the electric motor and the drive shaft, and on the inner sides of the electric motor and the drive shaft in the vehicle width direction, and overlapping the positions of the electric motor and the drive shaft in the front-rear direction.

A projection display apparatus includes a housing member containing a light source, an imager that modulates light emitted from the light source, and a projection unit that projects the light emitted from the imager on a projection surface. The projection display apparatus includes: a movement mechanism that moves an optical unit configured by the light source, the imager, and the projection unit, in a direction perpendicular to the projection surface while maintaining a positional relationship among the light source, the imager, and the projection unit.
