Abstract:
In a safety coupling for a motor vehicle for transmitting a driving torque between a machine shaft of an electric machine and a wheel drive shaft driving at least one wheel of a vehicle, torque is transmitted during disturbance free normal operation between the machine shaft and the wheel drive shaft via a releasable positive coupling. If a torque exceeding a limit value occurs, the releasable positive coupling is disengaged, and therefore an elastic coupling device at least briefly takes over the transmission of torque.
Abstract:
The functionality of a “Launch Control” is implemented in a hybrid vehicle, i.e. the hybrid vehicle can be accelerated to a maximum degree by starting the internal combustion engine immediately from the stationary state (S20), and acceleration takes place with the aid of the electric motor with full torque (S22) before a changeover to accelerating the internal combustion engine takes place (S24). The “Launch Control” differs from a further mode in which firstly acceleration takes place from the stationary state using a partial torque of the electric motor (S14), with the result that the internal combustion engine can be tow-started by means of the electric motor (S16) before a changeover to acceleration using the internal combustion engine (S18) occurs.

Abstract:
The invention relates to a device for adjusting the camber and/or toe of the wheels of a wheel suspension, particularly for motor vehicles, having a wheel carrier on which each wheel is rotatably supported and comprising a carrier part receiving the wheel and a guide part connected to the wheel suspension, between which rotating parts (26, 28) rotating about a rotation axis and preferably driven by an electric motor are disposed, bringing about a defined displacement of the carrier part and/or the guide part by the rotational actuation thereof for changing the camber and/or toe. According to the invention, a single adjusting drive (54) is provided for actuating the rotary parts (26, 28), by means of which the two rotary parts (26, 28) can be adjusted in different, particularly in opposite, directions.
Abstract:
A device for adjusting the camber and/or the toe of a vehicle wheel of a motor vehicle includes a wheel carrier, which has a wheel-side carrier part and an axle-side guide part, between which rotary parts that can be rotated relative to each other are arranged, wherein at least one of the rotary parts can be adjusted in both rotational directions by means of a drive and a gear stage in order to adjust the toe and/or the camber. The gear stage for the rotary part is configured as harmonic drive gear train having a driving, elliptical drive disk, and a stationary, internally toothed ring gear.
Abstract:
The invention relates to a steering device for a vehicle, with at least one actuator which pivots at least one steerable vehicle wheel by a steering angle which can be stipulated by way of a steering angle transducer. According to the invention, the actuator has a wheel-side pivoted part and an axle-side pivoted part which can be turned around their axes of rotation to one another and that to set the steering angle of the vehicle wheel, the wheel-side pivoted part can be deflected in the turning of the two pivoted parts by the swivel angle (φ) relative to the axle-side pivoted part.

Abstract:
The invention relates to a wheel suspension for motor vehicles, with at least one wheel-side support member which pivotally supports one vehicle wheel and at least one axle-side support member, between which at least one intermediate element is connected, in particular an actuator for setting the track angle and/or the camber angle (δ, ε) of the vehicle wheel. According to the invention the wheel-side support member and the axle-side support member are pressed into contact with one another by a pretensioning means with a pretensioning force (FV).
Abstract:
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.
Abstract:
A method is provided for steering a vehicle that is to be backed into a parking space. According to the method, starting from an initial position outside the parking space until it attains a parked position in said space, the vehicle reverses through five curve sections, each section flowing seamlessly into the next. The last four curve sections, when viewed from the driving direction belong to the following curve types: the second 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. Starting from the initial position of the vehicle, the entire reverse trajectory that is to be traveled to attain the parked position is determined and the steering during the reversing procedure of the vehicle is controlled by an electronic control system in according with the trajectory. 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.
