| 摘要 |
The present invention relates to a method for controlling the speed of a motor vehicle, a speed control system and a device for use with the speed control system. For improving the fuel economy, the method comprises monitoring at least one speed-related parameter of the vehicle (2), such as the accelerator pedal position determining a nominal speed based on said speed-related parameter, setting the engine (3) of the vehicle (2) in a driving mode or an idle mode at said nominal speed, setting the engine (3) of the vehicle (2) in an idle mode when the actual speed of the vehicle exceeds said nominal speed, setting the engine (3) of the vehicle (2) in the driving mode when the actual speed of the vehicle decreases to said nominal speed or falls below said nominal speed, and repeating, based on said fluctuations of the actual speed of the vehicle, said changes between driving mode and idle mode as long as the monitored speed-related parameter is substantially unaltered. The speed control system used at this method comprises at least monitoring means (4), calculating means (6) and setting means (8). |
