Abstract
In a device for regulating the speed of a vehicle, particularly an automotive vehicle, having an electronic regulator, at least one first storage for the storing of a first speed desired-value signal as well as a control arrangement for the storage are provided. In the regulator, a speed actual-value signal is compared with the speed desired-value signal and a corresponding setting signal is produced which actuates a setting member (13). There is also connected to the regulator an operating device (16) which comprises at least one button (19 or 20) for setting the storage to the speed desired-value signal, one button (17) for disconnecting the regulation as well as a restart button (18) for reactivating the regulation. Within the regulator there is provided a second storage (5) for storing a second speed desired-value signal which forms a so-called stack together with the first storage (4). The stack of the two storages can be so controlled by the control arrangement (16) that at suitable times the first or the second speed desired-value signal can be set in the first storage and in this way the previously stored speed desired-value signal can also be used for the regulation at a d…
