Abstract
A method for determining driving resistance in an insufficient warm-up state includes measuring driving data including at least first rolling resistance when a vehicle travels to include at least one constant-speed driving section in an insufficient warm-up state and determining a second rolling resistance based on the first rolling resistance measured in the constant-speed driving section, wherein the second rolling resistance is a rolling resistance predicted in the sufficient warm-up state.
Claims15
A method for determining driving resistance in an insufficient warm-up state, the method comprising:
- measuring driving data including at least first rolling resistance when a vehicle travels to include at least one constant-speed driving section in the insufficient warm-up state;
- and
- determining a second rolling resistance based on the at least one first rolling resistance measured in the at least one constant-speed driving section,
- wherein the second rolling resistance is a rolling resistance predicted in a sufficient warm-up state.
A method for determining a driving resistance in an insufficient warm-up state, the method comprising:
- measuring driving data of a vehicle, when the vehicle travels to include at least two driving sections having different accelerations in the insufficient warm-up state;
- and
- determining an inertia resistance determined as a product of an inertial mass and an acceleration based on the driving data measured in the at least two driving sections having the different accelerations,
- wherein the inertial mass is determined based on a difference in the acceleration and a difference in a first rolling resistance in the at least two driving sections having the different accelerations.
