Abstract
The present disclosure periodically monitors an oil condition through a temperature sensor installed in a driving motor of an in-wheel-type running gear, the generated torque of the driving motor, or the like and transmits oil condition information to a driver through a vehicle warning light.
Claims12
An oil monitoring system of an in-wheel-type running gear that manages safety of a vehicle by identifying oil deterioration in the in-wheel-type running gear, the system comprising:
- a temperature sensor mounted on an in-wheel motor of the in-wheel-type running gear and configured to measure a temperature of the in-wheel motor;
- a torque sensor configured to measure a torque generated by the in-wheel motor;
- and
- a vehicle controller configured to:
- estimate a temperature of oil in the in-wheel-type running gear through the temperature of the in-wheel motor or estimate a condition of the oil by using a wear amount of a gear through torque generation of the in-wheel motor;
- and
- transmit warning information about the oil to a display when a calculated deterioration degree of the oil is not less than a predetermined reference value.
An oil monitoring method of an in-wheel-type running gear that manages safety of a vehicle by identifying an oil condition in the in-wheel-type running gear, the method comprising:
- measuring a temperature of an in-wheel motor through a temperature sensor mounted on the in-wheel motor of the in-wheel-type running gear;
- measuring a torque generated by the in-wheel motor through a torque sensor mounted on the in-wheel motor;
- and
- transmitting warning information about oil to a display when a calculated deterioration degree of the oil is not less than a predetermined reference value, after estimating a temperature of the oil in the in-wheel-type running gear through the temperature of the in-wheel motor or estimating a condition of the oil by using a wear amount of a gear through torque generation of the in-wheel motor.
