A velocity-regulating system for motor vehicles has an electronic control device that produces control signals for regulating the velocity of the motor vehicle at a pre-specified target velocity and/or at a pre-specified distance from a preceding target object. The velocity-regulating system has an operating element whose actuation causes an intervention that influences the velocity regulation. The operating element is embodied as a touch-sensitive button that, when the button is pressed, produces a first intervention that influences the velocity regulation, and that, when the button is only touched, for the period during which button is touched, produces a second intervention that influences the active velocity regulation. Once the touching has ended, the original velocity regulation is continued.

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.

A method is provided for steering a vehicle that is to be backed into a parking space. Starting from an initial position outside the parking space, a reverse trajectory that is to be traveled to attain the parked position is determined. The vehicle reverses through five curve sections, and steering of the vehicle during the reversing procedure is controlled by an electronic control system in accordance with the reverse trajectory. When viewed from the driving direction, the second curve section represents a clothoid section, the third represents an arc section, the fourth represents an additional clothoid section and the fifth represents an additional arc section. In its initial position, the vehicle is at an angle to the longitudinal direction of the parking space and the first curve section, through which the vehicle reverses and which lies between the initial position and the start of the second curve section, is represented by a different geometrical function than the second curve section.

A device for electroacoustic sound generation in a motor vehicle with a sound pressure sensor, a signal processing unit, which is connected with the sound pressure sensor and receives and processes signals therefrom, and a loudspeaker unit with at least one loudspeaker connected with the signal processing unit. The sound pressure sensor is arranged in the area of the intake tract or exhaust gas tract of the motor vehicle. To ensure a sound generation that is as variable as possible and nevertheless authentic, a synthesizer that is connected with, or integrated in, the signal processing unit is used so that synthetic sound components can be added to the signals generated from the sound pressure sensor.

An apparatus for producing sounds corresponding to the operation of an internal combustion engine in the interior space of a motor vehicle is characterized by a pressure sensor () that detects fluctuations in pressure in a fresh air stream into the engine, an amplification device () for amplifying output signals of the pressure sensor, and at least one speaker () attached to the amplifier and arranged in the interior space of the vehicle for reproducing the amplified signals.

Method for determining geometric data for parking processes of vehicles, wherein the lateral distance between the vehicle and a curb is measured several times successively by means of a distance sensor attached to the vehicle as the vehicle is driven by the parking space. The angle of the longitudinal axis of a vehicle and the curb is ascertained by determining a sideways movement angle between the present longitudinal direction of the vehicle and a preset longitudinal direction, which angle results from the sideways movement of the vehicle as it is driven along, by determining a curb angle between the preset longitudinal direction and the curb, which angle results from the course of the curb contour, and by determining the angle between the present longitudinal axis of the vehicle and the curb by adding the angle of sideways movement and the curb angle.
