Abstract:
In a method and an apparatus for affecting the cornering performance of a motor vehicle, a transverse acceleration of the motor vehicle is determined, a desired transverse tilt of the motor vehicle defined based on the determined transverse acceleration, at least one actuator of an active suspension system of the motor vehicle is adjusted so that the motor vehicle assumes the desired transverse tilt, and an additional actuator intervening in the steering system of the motor vehicle. A yaw movement of the motor vehicle caused by the adjustment of the at least one actuator of the active suspension system is at least partially compensated by the additional actuator.
Abstract:
A method for operating a motor vehicle having at least one electric drive component which is cooled via at least one coolant circuit which is coupled thermally to a refrigerant circuit. In a first operating mode of the motor vehicle, an inlet temperature of a coolant of the at least one coolant circuit is set to a first value by active cooling by means of the refrigerant circuit. In a second operating mode, in particular a sports operating mode of the motor vehicle, the inlet temperature is lowered with respect to the first operating mode. As a result, more pronounced cooling of the components is made possible in the second operating mode, as a result of which the maximum driving power of the motor vehicle is increased.

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:
In a motor vehicle having two, in particular electrical, drives, a partial torque is in each case intended to be assigned to the individual drives from a demanded total torque, to be precise taking account of the energy efficiency on the one hand and the stability of the vehicle on the other hand. A first controller is responsible for taking account of the energy efficiency, and predetermines a bandwidth of possible partial torques for an individual drive. This bandwidth may be restricted by a second controller, when driving stability requires this. The second controller is coupled to appropriate sensors (yaw rate sensor, lateral acceleration sensor, longitudinal acceleration sensor) and knows the steering angle φ. In the course of interchanging data signals with a first control device, the partial torques are defined with the involvement of the second control device, for which purpose the first control device emits control commands.
Abstract:
The invention relates to a wheel suspension for motor vehicles, comprising a wheel carrier (14), which has a wheel-side carrier part (16) that rotatably supports a vehicle wheel (12) and an axle-side guide part (18), between which a control element is connected, wherein the wheel-side carrier part (16) can be pivoted about a pivot angle relative to the axle-side guide part (18) to set a toe angle and/or camber angle when the control element is actuated. According to the invention, the wheel carrier (14), in particular the guide part (18) thereof, is guided directly or indirectly on a linear guide (26) affixed to the body in form of a slotted guide, allowing movement in the vertical direction.
Abstract:
A wheel suspension for a motor vehicle includes a support element on the wheel-side rotatably mounting a vehicle wheel and a carrier element on the axle-side, wherein the carrier element on the wheel-side can be adjusted for setting a toe and/or camber angle relative to the support element on the axle-side, wherein the carrier elements on the axle-side and on the wheel-side are coupled to a universal joint in which webs of the carrier elements on the wheel-side and on the axle-side are articulated on a gimbal ring element by means of bearing points. The webs of the support elements are articulated on the gimbal ring element at the bearing points by means of ball joints.
Abstract:
The invention relates to an apparatus for adjusting camber and/or toe of a vehicle wheel having a wheel carrier (10) on which the wheel is rotatably mounted, the wheel guide element (10) having a carrier member (12) receiving the wheel, a guide member (14) on the axle side and at least one intermediately arranged actuating element (16, 18) for adjusting camber and/or toe of the vehicle wheel, which actuating element (16, 18) has a drive connection to at least one servomotor (26, 28). According to the invention, the carrier member (12) and the guide member (14) are each coupled by a cardanic articulated connection to a corresponding articulated fork (32, 34) and a supporting ring (40) connecting the articulated fork (32, 34) via bearing pins (38), and the servomotor (26, 28) is connected to the actuating element (16, 18) via a belt drive (30) which passes through an intermediate space (39) in the articulated forks (32, 34).
Abstract:
An apparatus for adjusting the camber and/or toe of a motor vehicle wheel includes a wheel carrier, on which the wheel is rotatably mounted. The wheel carrier is divided into a carrier member receiving the wheel via a wheel bearing, an axle-side guide member, and a bearing assembly arranged therebetween. The bearing assembly includes rotary parts which can be rotated relative to each other and relative to both the carrier member and the guide member and which interact with confronting inclined faces. The wheel bearing includes a radially outer bearing housing, which is clamped by the bearing assembly formed from the rotary parts into a plug-and-socket connection with the carrier member.
Abstract:
A motor vehicle can have multiple drive modes, for example rear wheel drive, four wheel drive, front wheel drive. Here, an active chassis device is used to make different adjustments, for example with respect to the toe-in angle and the camber angle, of a wheel or else with respect to wheel loads as a function of the drive load. As a result, the driving behaviour can be matched in each case in an optimum way to the drive mode, or conversely can be configured in such a way that changing the drive mode does not have a perceptible effect for the driver.
