A steer-by-wire system for a motor vehicle includes at least two wheels which are steerable independently of one another in a normal operating mode of the steer-by-wire system, at least two steering actuators, each one being assigned to one of the steerable wheels and being configured for adjusting a steering angle of the particular steerable wheel, and at least one steering electronics system which is signally connected to the steering actuators and which is configured for controlling the steering actuators individually on the basis of steering commands.

Steer-by-wire system, motor vehicle, and method for operating a steer-by-wire system

A motor vehicle has an electrically assisted steering system. A steering angle velocity of the motor vehicle, and a driver manual torque change applied by a driver of the motor vehicle are determined. At least the steering angle velocity and the driver manual torque change are analyzed to determine whether the driver manual torque change and the steering angle velocity are not correlated. An error signal is output if the driver manual torque change and the steering angle velocity are not correlated.

Operating motor vehicle electrically assisted steering

A method and apparatus for limiting an assistance-torque demand on an actuator, for example a servomotor, of a power steering system. An assistance-torque demand is received and examined based on a predetermined limit criterion. If a violation of the limit criterion is ascertained, a transient assistance-torque limit is adopted and progressively reduced so long as the violation of the limit criterion is ascertained. The assistance-torque demand is limited based on the transient assistance-torque limit. The limited assistance-torque demand is sent to an interface of the actuator of the power steering system.

A method for avoiding or reducing damage to a parked vehicle caused by a collision with an approaching vehicle performing a parking operation included determining, by the parked vehicle, a risk of collision, transmitting a warning signal if the risk of collision is sufficiently high, monitoring whether the approaching vehicle reacts to the warning signal, and performing a maneuver by the parked vehicle to avoid or reduce collision damage if there is no reaction. The maneuver may permit a controlled contact between the parked vehicle and the approaching vehicle to minimize the force of the contact. After such a controlled contact, a braking torque exerted by the parked vehicle is increased. Following completion of the damage avoidance maneuver, an estimate of the extent of the completed damage prevention is made and provided to the owner of the parked vehicle (including information about potential saved repair costs).

Method for preventing or reducing collision damage to a parked vehicle

A method for monitoring at least one traction battery of a motor vehicle includes the steps of determining basic data for the prediction of a deeply discharged state of the at least one traction battery by a battery monitoring system associated with the motor vehicle, transmitting the basic data to an external computer via a first communications link, determining an expected point in time of the deep discharge by the external computer, and transmitting a first warning signal to a first monitoring instantiation of the motor vehicle that can be specified if the determined point in time of the deep discharge is reached apart from an early warning time. A device for monitoring at least one traction battery of a motor vehicle is also disclosed.

A method and a device for automatically deactivating a coasting operating mode in a motor vehicle with an internal combustion engine is disclosed. An activated coasting operating mode is deactivated if the current vehicle speed exceeds a threshold value. The threshold value is set as the sum of a minimum vehicle speed and of a maximum permissible increase in speed.

Method and device for controlling a coasting operating mode in a motor vehicle with an internal combustion engine

A method for operating a vehicle system is provided. The method includes activating a starter-generator rotationally coupled to a crankshaft output in an internal combustion engine while combustion operation in the internal combustion engine is inhibited, operating the starter-generator to drive the crankshaft in a predetermined speed range while combustion operation in the internal combustion engine is inhibited, and activating combustion operation in a cylinder of the internal combustion engine in response to a combustion activation trigger.
