Abstract
The invention relates to a vehicle infotainment system, comprising a system-on-chip with a restart monitoring device. In this arrangement, the restart monitoring device is designed to determine a number of restarts of the system-on-chip and to deactivate the system-on-chip or to switch it in an idle mode when the number of restarts of the system-on-chip exceeds a predetermined threshold value. In this manner, the restart monitoring device can prevent a discharge of the battery of the vehicle by a faulty loop of restarts.
Claims13
A vehicle infotainment system having:
- a single-chip system having a restart monitoring device;
- wherein the restart monitoring device is configured to determine a number of restarts by the single-chip system;
- and
- wherein the restart monitoring device is configured to deactivate the single-chip system or to transfer it to an idle mode when the number of restarts by the single-chip system exceeds a prescribed threshold value;
- the single-chip system further having:
- a plurality of computer cores having a first portion of the computer cores and a second portion of the computer cores;
- wherein the plurality of computer cores are operable by means of a power supply;
- wherein the second portion of the computer cores is configured to identify a cyclic malfunction in the first portion of the computer cores and, on identification of a cyclic malfunction in the first portion of the computer cores, to disconnect the power supply for the first portion of the computer cores.
A motor vehicle having a vehicle infotainment system, the vehicle infotainment system comprising:
- a single-chip system having a restart monitoring device;
- wherein the restart monitoring device is configured to determine a number of restarts by the single-chip system;
- and
- wherein the restart monitoring device is configured to deactivate the single-chip system or to transfer it to an idle mode when the number of restarts by the single-chip system exceeds a prescribed threshold value;
- the single-chip system further having:
- a plurality of computer cores having a first portion of the computer cores and a second portion of the computer cores;
- wherein the plurality of computer cores are operable by means of a power supply;
- wherein the second portion of the computer cores is configured to identify a cyclic malfunction in the first portion of the computer cores and, on identification of a cyclic malfunction in the first portion of the computer cores, to disconnect the power supply for the first portion of the computer cores.
A method for preventing battery discharge by a vehicle infotainment system having a single-chip system having a plurality of computer cores having a first portion of the computer cores and a second portion of the computer cores, wherein the plurality of computer cores are operable by means of a power supply, the method involving:
- determination of a number of restarts by the single-chip system by a restart monitoring device of the single-chip system;
- and
- deactivation, or transfer to an idle mode, of the single-chip system by the restart monitoring device when the determined number of restarts exceeds a prescribed threshold value;
- and
- identification, by the second portion of the computer cores, of a cyclic malfunction in the first portion of the computer cores and, on identification of the cyclic malfunction in the first portion of the computer cores, disconnection of the power supply for the first portion of the computer cores.
