摘要:
A steering system (1) of a vehicle, having a steering wheel (2) which is connected mechanically to the steerable vehicle wheels (11) via a steering column (3). A superimposition actuator (26) which can be actuated independently of the driver by a control device (25) is provided for generating a superimposition variable (U). A superimposition device (6) superimposes a steering wheel variable (δH) which describes the steering actuation of the steering wheel (2) and the superimposition variable (U) to form an output variable. A steering actuator (19) sets a steering angle (δL) at the steerable vehicle wheels (20) as a function of the output variable. An actuating device (27) is provided which is actuated by the control device (25) in order to generate an actuating device torque (MS) which acts on the steering column. Here, the control device (25) at the same time actuates the superimposition actuator (26) and the actuating device (27), with the result that the steering angle (δL) and a reaction moment (MR) which results from the superimposition variable (U) and the actuating device torque (MS) and feeds back on the steering wheel (2) are influenced independently of the driver.
摘要:
The opening of vehicle doors often leads to collisions with stationary obstacles that are not visible to the occupants or with moving obstacles that approach the vehicle without being noticed. Thus to avoid collisions when vehicle doors are opened, the aim of the invention is to take any modifications to the environmental situation of the vehicle as a result of a movement of the vehicle and the detected objects into consideration. This allows a collision of the vehicle doors with the objects to be reliably avoided. To achieve this, in a first step the portable trajectory of a vehicle is determnined. In an additional step, the objects in the vicinity of the vehicle are detected and probable trajectories of said detected objects are determined. Respective probability ranges are then defined both for the vehicle and the pivoting zone of the vehicle doors and for the detected objects. The probability ranges of the pivoting zones of the vehicle doors are respectively compared with the individual probability ranges of the objects, in order to determine whether they overlap. If an overlap is identified, a response; signal that indicates the risk of a collision is generated.

摘要:
An automatic brake and steering system and method for a vehicle contains a sensor unit for sensing vehicle state and characteristic variables, and ambient conditions. Furthermore, a control unit and actuator devices are provided for setting the vehicle brake system and/or the vehicle steering system. In order to be able to carry out automatic avoidance maneuvers with maximum safety, an avoidance route is determined if there is an obstacle in the path of the vehicle. Thereby, if there is a further obstacle on the avoidance route, the strategy for determining the avoidance route is applied once more. If it is not possible to find a collision-free avoidance route, that route on which the difference between the remaining braking distance and the remaining distance from the obstacle is smallest is selected.
摘要:
In a method and apparatus for assisting the driver of a vehicle in maintaining a traffic lane limited by traffic lane markings, the traffic lane markings and the position of the vehicle in the traffic lane are detected. Upon an actual or impending change of traffic lanes a lane change warning is output to the driver of the vehicle in a first step, and a course correcting actuating intervention counteracting the lane change is carried out in a second step. The actuating intervention is carried out only if the change of traffic lanes is impermissible due to the type of traffic lane marking to be crossed during the traffic lane change, or if the lane change is not possible without danger due to collision-endangering objects present on the side of the traffic lane.
摘要:
A slip control system determines friction/slip characteristics of tires of a road vehicle equipped both with an antilock system to permit an individual brake pressure control on individual vehicle wheels. The front wheel brakes are connected to a primary output pressure space of the tandem master cylinder, and the rear wheel brakes are connected to a secondary output pressure space of the tandem master cylinder. A first bore stage of a housing of the tandem master cylinder forms a housing-defined boundary of the secondary output pressure space. An inner piston flange movably seals off a pressureless downstream chamber in relation to an inner portion of the first bore stage. An intermediate wall of the housing delimits the bore stage relative to a central bore stage which extends from a third bore stage receiving a primary piston. An actuating piston is displaceably guided in the central bore stage in a pressure tight manner and forms an axially movable, inner boundary of the primary output pressure space relative to a pressureless downstream chamber in the central bore stage which is bounded by the intermediate wall. An annular space is bounded in an axially movable manner by an inner piston flange of a secondary piston and by the intermediate wall and is connected to the pressure output of the controllable pressure source.
摘要:
A control system for a vehicle has a detection device for generating signals which describe the operating and vehicle state. The latter signals are supplied to a regulating and control unit which generates actuating signals for switching on and off a vehicle component that influences a brake servo device for automatically producing braking force if the accelerator pedal is not actuated by the driver. This “acceleration—automatic braking” mode is triggered if the brake pedal has been actuated in a prescribed manner within a defined period of time.
