Abstract
An inspection apparatus is configured to inspect damage on gears in a transmission that transmits a torque generated by a motor mounted as a drive source of a vehicle. The inspection apparatus comprising: a sensor configured to detect an AE signal in a meshing state of the gears; and a processor configured to determine presence or absence of occurrence of damage in the meshing state of the gears based on the AE signal.
Claims8
An inspection apparatus configured to inspect damage on gears in a transmission that transmits a torque generated by a motor mounted as a drive source of a vehicle, the inspection apparatus comprising:
- a sensor configured to detect an acoustic emission (AE) signal in a meshing state of the gears;
- a processor configured to determine presence or absence of occurrence of damage in the meshing state of the gears based on the AE signal;
- and
- a memory configured to store inspection date and time information based on the AE signal,
- wherein the processor is configured to identify, as a target of the inspection, meshing of the gears having a longest non-inspection period from a previous inspection time point in the inspection date and time information, and
- the processor is configured to identify, as the target of the inspection, the meshing of the gears having the longest non-inspection period in meshing information in a predetermined range acquired with a meshing position at a target stop position planned in an automated driving control of the vehicle as a reference.
An inspection method of an inspection apparatus, configured to inspect damage of gears in a transmission that transmits a torque generated by a motor mounted as a drive source of a vehicle, the inspection method comprising:
- detecting, by a sensor of the inspection apparatus, an acoustic emission (AE) signal in a meshing state of the gears;
- determining, by a processor of the inspection apparatus, presence or absence of occurrence of damage in the meshing state of the gears based on the AE signal;
- and
- storing, in a memory, inspection date and time information based on the AE signal,
- wherein the processor is configured to identify, as a target of the inspection, meshing of the gears having a longest non-inspection period from a previous inspection time point in the inspection date and time information, and
- the processor is configured to identify, as the target of the inspection, the meshing of the gears having the longest non-inspection period in meshing information in a predetermined range acquired with a meshing position at a target stop position planned in an automated driving control of the vehicle as a reference.
