A method for safeguarding a movement of a motor vehicle on an inclined ramp. Downhill from the motor vehicle, one or multiple collision object(s) is/are moved into a travel path specified by the ramp, so that in the event of a downhill movement of the motor vehicle on the travel path, a collision of the one or multiple collision object(s) with the motor vehicle reduces a speed of the motor vehicle while it is still on the ramp. Also described are a corresponding device, a parking facility, and a computer program.

Method and device for safeguarding a movement of a motor vehicle on an inclined ramp

A method for operating a vehicle in at least one parking process situation involves allocating at least one predetermined vehicle-specific or parking process situation-specific function to the at least one predetermined parking process situation of the vehicle. Whether the vehicle is in the at least one predetermined parking process situation is determined and the predetermined vehicle-specific or parking process situation-specific function allocated to the at least one predetermined parking process situation is presented to a vehicle user for activation or automatically activated when the vehicle is in the at least one predetermined parking process situation.

Method and device for operating a vehicle

A method of moving a vehicle from a start position to end position when the end position cannot be detected by the vehicle's built-in sensors involves determining the start position by a mobile terminal or by the vehicle and determining the end position by the mobile terminal. A driving trajectory of the vehicle is planned within the vehicle, a driving maneuver of the vehicle is initiated by the vehicle or the mobile terminal, and the planned driving maneuver is carried out to reach the end position.

Method and device for moving a vehicle into a target position

In a method, a steeringwheel torque for the steering wheel of a motor vehicle is determined. In this context, a steering angle for steered wheels is predefined by the driver by means of the steering wheel. A steering torque which represents the forces on the vehicle axle acts on the steering wheel. A desired manual torque (M_soll) is determined here using at least one axle model. The desired manual torque is then superimposed on the actual steeringwheel torque (M_ist).

Method for determining a steering-wheel torque

The invention relates to a method and a device for coordinating multiple driving system devices of a vehicle by means of a co-ordination device. The driving system devices produce output signals according to the current driving state of the vehicle. In the coordination device, a result control signal is produced from the output signals and is used as a standard set value for directly influencing the driving state by means of the actuator devices of the vehicle and/or a parameter result signal is produced and used for influencing the regulating and/or control parameters of a driving state regulating system or driving state control system.

Vehicle steering system

A vehicle steering system has a steering grip, in particular a steering wheel, which is operated by the driver, an actuating unit which operates steered vehicle wheels, and a manual force regulator which is coupled via a flexible coupling element with the steering grip and simulates parameter-dependent steering forces on the steering grip. A damping device is provided for reducing the formation of vibrations between the steering grip and the manual force regulator. The damping device interacts with the steering grip either directly or indirectly to damp relative motions between the steering grip and the manual force regulator.

A vehicle with a steering handle, which can be actuated by a driver of the vehicle, with at least one steerable vehicle wheel, which is actuated as a function of actuations of the steering handle, with a control system, which allows operation of the steering system on a steer-by-wire level and on a fall-back level and, at least in an emergency, switches from the steer-by-wire level to the fall-back level, with an electric and/or electronic coupling device, which couples the steering handle to the steerable vehicle wheel on the steer-by-wire level, and with a hydraulic and/or mechanical coupling device, which couples the steering handle to the steerable vehicle wheel on the fall-back level.

Steering system for a vehicle

A steering system for motor vehicles, in which a steering member or steering wheel and the steered vehicle wheels are hydraulically positively coupled for the steering actuation of the wheels. An additional servo system is provided which is responsive to torque transmitted between the steering wheel and master unit of the hydraulic system.

Motor vehicle steering system

A steering system for motor vehicles, has a steering handle, for example steering handwheel, capable of being operated by the driver. A steering actuating drive provides for the steering adjustment of steerable vehicle wheels. A steering-angle desired-value encoder is capable of being operated by the steering handle, and a steering-angle actual-value encoder operates via the steerable vehicle wheels. A regulating and control arrangement operates the steering actuating drive as a function of a comparison of the desired and actual values of the steering angle. The risk of a collision between a vehicle equipped with the steering system and an obstacle is reduced, and the steering system is suitable for steer-by-wire operation by equipping the steering system with collision prevention apparatus which determine steering angles (collision steering angles) making a collision possible between the motor vehicle and an obstacle. The regulating and control arrangement hinders or prevents the setting of a desired steering angle coinciding with one of the collision angles.

Steering system for motor vehicles

A hydraulic power steering system for motor vehicles which is suitable for a steer-by-wire operation, having a steering handle which can be operated by a driver. A servo motor operates steered vehicle wheels. A servo valve operates the servo motor and is constructed as a rotary slide valve arrangement having mutually rotationally movable control parts which, together, are pushed by a spring system into a normal position relative to one another. An actuator is coupled with the control parts for their rotational adjustment relative to one another and operates the servo valve. A desired steering angle value generator is operated by way of the manual steering handle. An actual steering angle value generator is operated by way of the steered vehicle wheels. An automatic control circuit operates the actuator as a function of a comparison of the desired and actual steering angles. In order to improve this power steering system with respect to its control performance, an angle sensor is coupled with the control parts which detects their relative angular position. The automatic control circuit takes into account this relative angular position when operating the actuator.

Power steering system for motor vehicles

A steering system for vehicles can be operated in a normal mode, in which a steering handle actuated by the driver and steered vehicle wheels are connected to one another via a control system, and in an emergency mode, in which the steering handle and the steered vehicle wheels are positively coupled. To achieve a steering system which increases the operational reliability of the steering system by simple design measures, a steering-angle control unit for a steering-angle actuator actuates the steered vehicle wheels. The control unit contains a first steering-angle control system, and a manual-torque control unit for a manual-torque actuator actuates the steering handle for the purpose of simulating manual torques. The control unit also contains a first manual-torque control system, and the steering-angle control unit comprises a second manual-torque control system, which is connected redundantly with the first manual-torque control system of the manual-torque control unit. The manual-torque control unit comprises a second steering-angle control system which is connected redundantly with the first steering-angle control system of the steering-angle control unit.

In order to allow a traffic-lane following device in a vehicle to be used at relatively high vehicle speeds, a steering system is provided with a steering handle and a steering run which couples the steering handle to vehicle steered wheels. A servomotor is coupled to the steering run. A servovalve is arranged in the steering run and has a first control part (which is associated with a section on the steering handle side of the steering run) as well as a second control part (which is associated with a section on the vehicle steered wheel side of the steering run) to operate the servomotor as a function of relative movements between the control parts. An actuating drive is coupled to the section on the steering handle side of the steering run and is used to produce a steering force. A regulating and control arrangement uses a sensor system to determine required steering angle values which allow a traffic lane to be followed and uses a steering angle sensor to determine actual steering angle values. The actuating drive is operated as a function of a comparison of the required and actual steering angles, in which the steering angle sensor interacts with the section on the vehicle steered wheel side of the steering run.

Steering system for a vehicle equipped with a traffic-lane following device

A steering system of a non-tracked motor vehicle has steered vehicle wheels are connected in normal operation with respect to the effect with a steering handle only by way of an electronic automatic control unit which continuously monitors itself with respect to a correct operation. As a function of a desired-value generator, which is operated by the steering handle, this automatic control system operates an adjusting drive for the steering adjustment of the steered vehicle wheels. In the event of a malfunctioning of the automatic control system, a forced coupling is automatically switched effective between the steering handle and the steered vehicle wheels. This also takes place if the performance limit of the adjusting drive is reached so that the driver is capable of assisting the adjusting drive by the driver's manual force on the steering handle.

Steering system for non-tracked motor vehicles

High functional reliability for a vehicle steering system that can be switched between a normal mode with a steer-by-wire level and an emergency mode with a fall-back level is achieved by providing that the fall-back level has a hydraulic system which contains a manual-side double-acting piston-cylinder unit which is actuated with a steering handle, e.g. steering wheel. The unit is positively coupled hydraulically to a wheel-side double-acting piston-cylinder unit which actuates steered vehicle wheels. A hydraulic charging system has a hydraulic pump, the inlet side of which is connected to a hydraulic-fluid reservoir. Switchable hydraulic couplings are provided for hydraulically coupling and decoupling the hydraulic system of the fall-back level and the hydraulic charging system to and from one another, respectively.
