SPEED CONTROLLER AND METHOD FOR IMPROVING THE TRANSIENT STATE OF A SPEED CONTROLLER |
| 摘要 |
A speed regulator 120 and a method for operating it. The speed regulator guides an engine system 130 in a vehicle towards a target speed vdes, whereby the vehicle assumes an actual speed vact which describes a zeroing pattern towards the target speed vdes. Priming of the speed regulator 120 is effected on the basis of knowledge about a road section ahead of the vehicle, whereby the magnitude of at least one fluctuation in the zeroing pattern relative to the target speed vdes is reduced. A zeroing pattern with fewer overshoots and undershoots is thus achieved, resulting in reduced fuel consumption. |

1. A method for operating a speed regulator which guides an engine system in a vehicle towards a target speed vdes, causing the vehicle to assume an actual speed vact which describes a zeroing pattern towards the target speed vdes, the method comprising obtaining knowledge about a road section ahead of movement of the vehicle; feed-forwarding of the speed regulator based on the knowledge about a road section ahead of movement of the vehicle, for reducing a magnitude of at least one fluctuation in the zeroing pattern relative to the target speed vdes. |
