Abstract

The disclosure relates to a vehicle architecture for controlling and regulating an electric drive of an electric or hybrid vehicle, having a power electronics system which is connected firstly to the electric drive and secondly to a battery or to a battery system. A battery management system is associated with the battery or the battery system. The vehicle architecture comprises a master controller or a controller which is equipped with a master functionality into which functionalities at least of the battery management system and of the power electronics system of the electric drive are exported.

First claim

1 . A vehicle architecture for controlling and regulating an electrical drive of at least one of an electric vehicle and a hybrid vehicle, the vehicle architecture comprising:
power electronics connected to the electrical drive and to at least one of a battery and a battery system; a battery management system that is assigned to the power electronics; and a master control device that is equipped with a master functionality, to which functionalities of at least the battery management system and of the power electronics of the electrical drive are transferred.

2 . The vehicle architecture as claimed in claim 1 , wherein the master control device is connected to a navigation system.

3 . The vehicle architecture as claimed in claim 1 , wherein the master control device is configure to act upon a cooling system for the battery or the battery system.

4 . The vehicle architecture as claimed in claim 1 , wherein the master control device is configured to act upon the power electronics such that a torque requirement of the at least one of the electric vehicle and the hybrid vehicle is reduced.

5 . The vehicle architecture as claimed in claim 1 , wherein the master control device is configured to optimize a range for an expected route using information from the navigation system.

6 . The vehicle architecture as claimed in claim 1 , wherein the master control device configured to control at least one of the following vehicle components via additional connections:
an electrical air-conditioning system compressor; an AC/DC converter; at least one heating device; a DC quick-charging interface; and a DC/DC converter for a vehicle electrical system.

7 . A method for controlling and regulating an electrical drive of at least one of an electric vehicle and a hybrid vehicle, the method comprising:
a) transmitting information from a navigation system to a master control device of a vehicle architecture; b) optimizing a range for an expected route by controlling a cooling system for at least one of a battery and a battery system; and c) reducing a torque requirement of the vehicle by acting upon power electronics of the electrical drive.

8 . The method as claimed in claim 7 , further comprising:
optimizing operation of the at least one of the electric vehicle and the hybrid vehicle using the information from the navigation system.

9 . The method as claimed in claim 7 , wherein at least one of adaptive control systems and adaptive regulating systems are implemented in the master control device and are matched to at least one of a driver's driving style and an expected driving situation.

10 . The method as claimed in claim 7 , wherein the master control device of the vehicle architecture comprises the functions of at least one of a battery management system, a control device of the power electronics, and control devices of additional components.
