1. A control and monitoring device of a vehicle, comprising:
- at least one controlled brake system, which during braking adjusts at least one of a brake slip and a brake pressure to a setpoint value, including at least one brake control unit; and
a device for monitoring a tire pressure and a tire air temperature of at least one tire, having at least one tire sensor, which transmits a signal representing at least one of an individual tire pressure and an individual tire air temperature of the particular tire, to at least one tire-monitoring control unit;
wherein the at least one tire-monitoring control unit and the at least one brake control unit are integrated in one sub-assembly and configured for exchanging data among each other,wherein the at least one controlled brake system includes at least one of an anti-lock braking system (ABS) and an electronic braking system (EBS), and wherein the at least one brake control unit includes at least one of an electronic control unit-ABS (ECU-ABS) and an electronic control unit-EBS (ECU-EBS),wherein routines are implemented in the at least one EBS brake control unit, with whose aid a brake disk temperature of a brake disk of a disk brake of the vehicle is estimated based on brake and vehicle parameters, including at least one of brake duration, brake pressure, deceleration and vehicle loading, using an estimation algorithmwherein a measured tire air temperature is used by the at least one tire-monitoring control unit to estimate a brake disk temperature of a brake disk of the particular tire to provide an estimated brake disk temperature, andwherein routines are implemented at least one of in the at least one EBS brake control unit and in the at least one tire-monitoring control unit for verifying the estimated brake disk temperature based on the measured tire air temperature of the tire assigned to the brake disk with respect to the estimated brake disk temperature based on the brake and vehicle parameters, so as to increase a fault tolerance of the brake system.

Abstract
A control and monitoring device of a vehicle, including at least one controlled brake system (ABS, EBS), which during braking adjusts the brake slip and/or the brake pressure to a setpoint value, including at least one brake control device (ECU-EBS, ECU-TEBS) as well as a device (TPMS) for monitoring the tire pressure and/or the tire air temperature of at least one tire, including at least one tire sensor, which transmits a signal representing the individual tire pressure and/or the individual tire air temperature of the particular tire, to at least one tire-monitoring control unit (ECU-TPMS). The at least one tire-monitoring control unit (ECU-TPMS) and the at least one brake control unit (ECU-EBS, ECU-TEBS) are integrated in one subassembly and are configured for the exchange of data among each other.
