Method of controlling the drive train of a motor vehicle, and integrated drive train control system
First Claim
1. A method of controlling a drive train of a motor vehicle, which comprises:
- interpreting a position of an accelerator pedal as a torque selected from the group consisting of a wheel torque and a transmission output torque desired by a driver of the motor vehicle, and calculating, from the position of the accelerator pedal, desired values for an engine and a transmission of the motor vehicle;
receiving, with a calculation device, signals representing the position of the accelerator pedal and a position of a brake pedal, and generating from the signals central control parameters for drive sources and decelerating units of the drive train of the motor vehicle;
delivering to the data calculation device data on local environmental pollution and taking the data into account in the generating step such that a driving mode of the motor vehicle is adapted to current environmental conditions and is indicated to the driver; and
automatically activating an operating mode adapted to the current environmental conditions.

Abstract
The drive train of a motor vehicle is controlled by interpreting the position of the accelerator pedal as a wheel torque or transmission output torque desired by the driver. This information is utilized together with the position of the brake pedal for calculating central control parameters for the drive sources and decelerating units of the drive train. Data on local environmental pollution are taken into account in such a way that a drive mode of the motor vehicle, ascertained to whatever the current environmental conditions are, is ascertained and indicated to the driver. Unless the driver rejects this drive mode for special reasons, it is performed automatically.

7. An integrated drive train control system for a motor vehicle having an accelerator pedal, a brake pedal, and a drive train with drive sources and decelerating units, the control system comprising:
-
a calculation device receiving a signal representing a position of the accelerator pedal and of the brake pedal respectively, said calculation device interpreting the position of the accelerator pedal as a torque selected from the group consisting of a wheel torque and a transmission output torque desired by the driver of the motor vehicle; an information channel connected to said calculation device, said information channel furnishing to said calculation device data on local environmental pollution; said calculation device generating central control parameters for the drive sources and the decelerating units of the drive train on the basis of the respective positions of the brake pedal and the accelerator pedal, and taking into account the data on local environmental pollution such that a driving mode of the motor vehicle is adapted to the environmental conditions through the central control parameters. - View Dependent Claims (8, 9)
