摘要:
The invention relates to a motor vehicle brake system comprising an active service brake unit (1) and an electrically controllable parking brake unit (2). The service brake unit (1) has a measurable and adjustable active service brake device (5, 7) (for example, a traction control system/electronic stability programme, hydraulic control unit, analogue/active booster, brake-by-wire system, etc.). To provide an electrical parking brake function which is convenient to operate while making the overall assembly of the motor vehicle brake system as easy as possible, the invention provides for the service brake unit (1) and the parking brake unit (2) to be interconnected in such a way that when an operating element (9, 17) is actuated for the parking-brake function or if an equivalent control signal of an electronic driving assistance system is present a suitable component of either the service brake unit (1) or the parking brake unit (2) is used for braking and/or locking or blocking the motor vehicle. This type of interconnection has the advantage of providing a constant exchange of information or data between the parking brake unit and the service brake unit and therefore allows for the coordinated use of the electrically controllable friction brake (8) of the service brake unit and a locking device (11) of the parking brake unit (2).

The invention relates to a method for detecting the driving torque during the starting of a vehicle, comprising the following steps: model-based detection of idling performance of the motor; comparing model output values with relevant measurement values or the values derived therefrom and detecting the vehicle driving torque in accordance with the comparison made. The device for detecting the driving torque during the starting of a vehicle comprises a model of the idling performance of the motor, a comparator for the model output values and the relevant measurement values or the values derived therefrom, and a sensing device for detecting the driving torque of the vehicle in accordance with comparison results. The invention further relates to a method and a device for detecting an externally caused variable driving or braking a vehicle and for providing asistance during climbing. Furthermore, the invention also relates to methods and devices for detecting externally caused variables/moments and for providing assistance during climbing.

The invention relates to a device and method for driving a motor vehicle braking system, allowing to detect, via a distance sensor, the behaviour of a driver's foot immediately before the actuation of the brake pedal. Various functions are defined through the determination of ranges of variable pairs A-D representing the distance 's' between the driver's foot and the brake pedal as well as the foot speed 'v'. Specifically, virtual actuation paths S1so11, S2so11 may be determined from actual variable pairs s, v. These virtual actuation paths S1so11, S2so1 allow for the determination of a pressure specification for the pressure regulator through an actuation characteristic pso11 = f(s).

The proposal is for a braking force amplifier fitted with a device for finding an initial force applied to a brake pedal. The device, which uses a pressure transducer to measure the initial force, is fitted according to the invention between the end of an actuating rod (20) connected to the brake pedal (9) and a valve piston (17) actuating a control valve of the braking force amplifier. The pressure transducer (24, 25) is subjected thereby to the effect of a pressure in a pressure chamber (26) constructed in an elastic compound or an elastomer (27).

The invention relates to a device for stabilising a vehicle, in particular after a collision against a lateral carriageway boundary, comprising a lane recognition system (1), with which information relating to the course of the lane (K act ) is determined or detected, a collision detection unit, which identifies a collision (T crash ) of the vehicle, in particular against the lateral lane carriageway boundary, on the basis of signals from at least one sensor or on the basis of a driving state variable (ay, ax, V veh ), determines an, in particular electrically controllable, steering actuator for steering a steering system, and an, in particular electrically controllable, brake actuator for controlling one or more wheel brakes, a target path determination unit, which determines a target path (K ref ) for the vehicle, on the basis of the course of the lane determined or detected before or at the time of the collision, and a controller (2), which causes a guiding of the vehicle onto the target path and/or a stabilisation of the vehicle via a steering intervention, in particular a control of the steering actuator, and/or using individual wheel brake interventions, in particular a control of the brake actuator, and a method for stabilising the vehicle.
