## 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.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The vehicle infotainment system as claimed in claim 1, wherein the number of restarts is a number of restarts per unit time.

### Claim 3 (depends on 1)

The vehicle infotainment system as claimed in claim 1, wherein the number of restarts is an absolute number; and
wherein the restart monitoring device is configured to reset the number of restarts when the single-chip system is successfully started up.

### Claim 4 (depends on 1)

The vehicle infotainment system as claimed in claim 1, wherein the restart monitoring device is configured to limit a wakeup function of the single-chip system when the number of restarts exceeds the prescribed threshold value.

### Claim 5 (depends on 4)

The vehicle infotainment system as claimed in claim 4, the single-chip system having:
an interface for receiving a wakeup signal;
wherein the restart monitoring device is configured to prevent the single-chip system from waking up when a wakeup signal is received via the interface when the number of restarts exceeds the prescribed threshold value.

### Claim 6 (depends on 5)

The vehicle infotainment system as claimed in claim 5, the single-chip system further having:
a startup memory unit that stores a program code executed for a startup process of the single-chip system;
a semipermanent memory unit;
wherein the restart monitoring device is implemented in the startup memory unit;
wherein the restart monitoring device is configured to store the determined number of restarts in the semipermanent memory unit;
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; and
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.

### Claim 7 (depends on 6)

The vehicle infotainment system as claimed in claim 6, the single-chip system further having: a memory unit embodied as a NAND memory.

### Claim 8 (depends on 7)

The vehicle infotainment system as claimed in claim 7, wherein the number of restarts is a number of restarts per unit time.

### Claim 9 (depends on 7)

The vehicle infotainment system as claimed in claim 7, wherein the number of restarts is an absolute number; and
wherein the restart monitoring device is configured to reset the number of restarts when the single-chip system is successfully started up.

### Claim 10 (depends on 1)

The vehicle infotainment system as claimed in claim 1, the single-chip system further having:
a startup memory unit that stores a program code executed for a startup process of the single-chip system;
a semipermanent memory unit;
wherein the restart monitoring device is implemented in the startup memory unit; and
wherein the restart monitoring device is configured to store the determined number of restarts in the semipermanent memory unit.

### Claim 11 (depends on 1)

The vehicle infotainment system as claimed in claim 1, the single-chip system further having: a memory unit embodied as a NAND memory.

### Claim 12

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.

### Claim 13

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
