Electronically actuated drive train in a motor vehicle and an associated operating method
First Claim
1. A method for operating an electronically actuated drive train in a motor vehicle, the method comprising:
- determining drive control signals for actuating a drive unit and gearbox control signals for actuating a manual gearbox from a power request of the driver of the vehicle, providing a predefined or predefinable driving style which is used to determine the control signals and can be selected from a range from minimum energy or fuel consumption up to maximum power output, wherein the predefined driving style is defined at the outset of vehicle travel and is not adapted to the driving style of the driver while the driver is driving, taking the predefined driving style into account in the determination of the drive control signals and the gearbox control signals, taking the local position of the motor vehicle into account in the determination of the drive control signals and the gearbox control signals.
