Method for determining the driving resistance of a vehicle |
| 摘要 |
A method for determining the driving resistance of a vehicle by taking into account a value for the vehicle mass is described. Before beginning to drive, the vehicle mass and driving resistance coefficients are estimated with an estimation method by taking into account sensor signals, and an initial value for the driving resistance is calculated from the vehicle mass and the driving resistance coefficients. A corrected value for the driving resistance and the vehicle mass is calculated while driving, based on measured driving-related values, which are measured in chronological succession. |

1. A method of determining a driving resistance of a vehicle, wherein the driving resistance is calculated by taking into account a value of a vehicle mass, the method comprising:
before driving begins, estimating the vehicle mass and driving resistance coefficients with an estimating method by taking into consideration sensor signals, determining from the estimated vehicle mass and the estimated driving resistance coefficients an initial value of the driving resistance, while driving, consecutively measuring driving-related values, and while driving, determining corrected values for the driving resistance and for the vehicle mass based on the measured driving-related values. |
