Abstract
A motor vehicle has a transmission with an automatic operating mode in which the transmission ratio is changed automatically by a control device and a manual operating mode in which the transmission ratio is changed by the driver by means of a ratio-selector device. The control device automatically switches from the manual to the automatic mode, e.g., when the driver makes or answers a call on a mobile telephone.
Claims8
A motor vehicle comprising an engine, a transmission with a device for changing a transmission ratio, a control device, and a ratio-selector device, wherein the transmission has a first operating mode in which a change of the transmission ratio is initiated by the control device, and a second operating mode in which the change of the transmission ratio is initiated by the ratio-selector device, and wherein a switch-over between said operating modes can be performed automatically by the control device;
- wherein the control device performs the automatic switch-over in response to at least one signal;
- and
- wherein the at least one signal comprises a first signal causing a switch-over to the first operating mode and an optional second signal causing a switch-over to the second operating mode.
A motor vehicle comprising:
- an engine, a transmission with a device for changing a transmission ratio, a control device, and a ratio-selector device, wherein the transmission has a first operating mode in which a change of the transmission ratio is initiated by the control device, and a second operating mode in which the change of the transmission ratio is initiated by the ratio-selector device, and wherein a switch-over between said operating modes can be performed automatically by the control device;
- wherein the control device performs the automatic switch-over in response to at least one signal;
- wherein the at least one signal comprises a first signal causing a switch-over to the first operating mode and a second signal causing an optional switch-over to the second operating mode;
- and
- wherein the second signal does not cause the optional switch-over if the transmission was set to the first operating mode already before the first signal occurred.
A motor vehicle comprising an engine, a transmission with a device for changing a transmission ratio, a control device, and a ratio-selector device, wherein the transmission has a first operating mode in which a change of the transmission ratio is initiated by the control device, and a second operating mode in which the change of the transmission ratio is initiated by the ratio-selector device, and wherein a switch-over between said operating modes can be performed automatically by the control device;
- and
- wherein a transmission ratio selected under the first operating mode remains in effect during a switch-over to the second operating mode.
A motor vehicle comprising an engine, a transmission with a device for changing a transmission ratio, a control device, and a ratio-selector device, wherein the transmission has a first operating mode in which a change of the transmission ratio is initiated by the control device, and a second operating mode in which the change of the transmission ratio is initiated by the ratio-selector device, and wherein a switch-over between said operating modes can be performed automatically by the control device;
- wherein the at least one signal comprises a first signal causing a switch-over to the first operating mode and a second signal causing a switch-over to the second operating mode, the first signal and the second signal being generated by an electronic device that comprises a communication device in the form of a mobile telephone;
- and
- wherein the first signal is at least representative of one of the set of situations consisting of an incoming telephone call, an outgoing telephone call, an intent of the driver to make a telephone call, and an intent of the driver to answer a telephone call.
