Abstract:
Système de commande (32; 42) de l'activation d'un actionneur électrique de freinage (3), comprenant un premier dispositif (19) pour convertir une manœuvre d'un organe (1 ) manœuvrable par un conducteur en un ordre de commande d'activation de l'actionneur électrique de freinage et un deuxième dispositif (31; 41 ) pour convertir une manœuvre de l'organe manoeuvrable par le conducteur en un ordre de commande d'activation de l'actionneur électrique de freinage, caractérisé en ce que le deuxième dispositif n'émet aucun ordre d'activation de l'actionneur électrique tant qu'une valeur seuil d'un paramètre relatif à l'organe manœuvrable n'est pas franchi et émet un ordre d'activation de l'actionneur électrique indépendant de la valeur du paramètre dès que la valeur seuil du paramètre est franchie.
Abstract:
The invention relates to a pedal travel simulator (1) for a powershift braking system. The pedal travel simulator (1) has a spring element (3) as the restoring means, a damper (6) and a force limiter (4), which is connected in series to the damper (6). The force limiter (4) can have a pre-tensioned spring element (7). During the rapid movement of a brake pedal (2), e.g. during an emergency or panic braking procedure, the force limiter (4) reduces a force that the damper (6) exerts on the brake pedal (2).
Abstract:
The invention relates to an electrically controlled braking system and its associated control method. Said system and method are characterised in that the service braking system can be activated by two service brake controls (4, 6) which can be actuated independently from each other by the driver. The main advantage of the present invention is that in case of a faulty service brake control (4), e.g. a brake pedal module, vehicle braking can be implemented with the aid of the service braking system through the second service brake control (6). Additional functions for the braking system, such as anti-blocking system and antiskid system, dynamic translation regulation, braking force amplifier, etc. can be implemented. The redundant design of the actuation system for said service braking system provides a high degree of operation safety, since full braking functionality can be maintained even in case of emergency braking.
Abstract:
A brake power detector (19) which is connected to the brake pedal (20) of a motor vehicle detects actuations of the brake pedal with several sensors (26, 55) and converts them into electrical signals. The brake pedal is connected to a piston (37) which moves inside a cylinder (42) by means of a rotationally arranged pressure rod (30). A variable volume pressure chamber (61, 45) filled with gas is provided inside said cylinder. Said pressure chamber can be at least partially filled with hydraulic fluid (46). The gas is compressed by the piston (37) when the brake pedal is actuated, thereby increasing the reaction force exerted upon said brake pedal.
Abstract:
The invention concerns an electric motor wheel brake for a vehicle, in which the active braking forces or brake moments and the actuator control signals are determined for each wheel brake (28, 30) by corresponding measuring devices (40, 42). Implausible deviations are detected by comparison on the basis of these signals and the fault signal is detected and processed in an appropriate manner by means of the corresponding signals from the other wheel brake on the same and/or other axles.

Abstract:
Die Erfindung betrifft eine Vorrichtung zur Kraftsimulation an einem Betätigungselement eines Fahrzeuges, vorzugsweise ein Pedalsimulator, welcher eine haptische Rückmeldung über ein vorgegebenes Kraft-Weg-Verhalten vermittelt, umfassend eine Kolben-Zylinder-Einheit (5, 12), wobei ein Kolben (5) über eine Kolbenstange (4) mit dem Betätigungselement (3) verbunden ist, welches den Kolben (5) innerhalb des Zylinders (12) entgegen einer Rückstell kraft axial bewegt. Bei einer Vorrichtung, bei welcher der Fahrzeugnutzer das gleiche Gefühl übermittelt bekommt, wie bei einer hydraulischen Betätigungseinrichtung, drückt der Kolben (5) gegen eine mehrteilige, elastische Anordnung (13, 14, 15), welche in Abhängigkeit von dem zurückgelegten Weg des Kolbens (5) eine Rückstell kraft oder eine Vorschubkraft gegenüber dem Kolben (5) erzeugt.
