Energy-optimized acceleration control for motor vehicles

摘要

An energy-optimized acceleration control is provided for a motor vehicle having an internal-combustion engine and/or an electric drive motor, a transmission unit and an accelerator element to be operated by the driver for accelerating the motor vehicle. In the course of the restoring force, when the accelerator element is operated, an inflection point with an increased restoring force is provided. The acceleration control is set up for operating the motor vehicle in two different operating modes, wherein during operation of the accelerator element leading to a reaching of the inflection point, the acceleration control changes into an energy-optimized acceleration mode.

主权项

1. An acceleration control method for a motor vehicle comprising at least one of an internal-combustion engine and an electric motor, and a transmission unit and an accelerator element operable by the driver for accelerating the motor vehicle, the method comprising the acts of:
providing an accelerator element operable with an inflection point at which an increased restoring force occurs; providing an acceleration control by which the motor vehicle is operable in at least two different operating modes, including an energy-optimized acceleration mode during which adaptation of a parameterization of at least one of a characteristic engine diagram, a generator control, and characteristic shifting curves for the motor vehicle reduces an amount of fuel consumption that occurs during an acceleration of the motor vehicle as compared to an amount of fuel consumption that would have occurred during the acceleration without said adaptation; and during operation of the accelerator element, changing the acceleration control into the energy-optimized acceleration mode upon reaching the inflection point.
