INTEGRATED GRADE AND PITCH ESTIMATION USING A THREE-AXIS INERTIAL-MEASURING DEVICE |
| 摘要 |
A system for use at a vehicle to estimate vehicle pitch angle and road grade angle, in real time and generally simultaneously. The system includes a sensor configured to measure vehicle pitch rate, a processor, and a computer-readable medium. The medium includes computer-executable instructions that, when executed by the processor, cause the processor to perform operations comprising estimating, using an observer and the vehicle pitch rate measured by the sensor, an estimated vehicle pitch rate. The operations further comprise estimating, using an observer and the measured vehicle pitch rate, the vehicle pitch angle, and estimating, based on the estimated vehicle pitch rate and the vehicle pitch angle estimated, the road grade angle. |

1. A system, for use at a vehicle to estimate vehicle pitch angle and a road grade angle, in real time and generally simultaneously, comprising:
a sensor configured to measure vehicle pitch rate; a processor; and a computer-readable medium comprising computer-executable instructions that, when executed by the processor, cause the processor to perform operations comprising:
estimating, using an observer and the vehicle pitch rate measured by the sensor, an estimated vehicle pitch rate;estimating, using an observer and the measured vehicle pitch rate, the vehicle pitch angle; andestimating, based on the estimated vehicle pitch rate and the vehicle pitch angle estimated, the road grade angle. |
