  • Publication number: 20050173980
    Abstract: The most important aspect of brake systems in motor vehicles functioning according to the brake-by-wire principle is that the driver's braking requirements are detected quickly and reliably. Fulfilling this requirement primarily depends on the pedal sensor system associated with the brake pedal and its measuring devices for determining the characteristic values of the brake pedal actuation. The present invention provides for at least two measuring devices for determining the braking requirement, with such measuring devices sensing the same characteristic value of the brake pedal actuation, e.g. the brake-pedal actuation force, brake-pedal travel or brake-pedal angle. These braking requirement signals are compared to a signal from a third measuring device in order to monitor the braking requirement measuring devices.

  • Patent number: 6802401
    Abstract: The present invention relates to a device and a method for controlling an electrically actuated parking brake. Especially, a tip switch is provided which is movable to adopt a tensioning position, a release position, and a neutral position. For example, when the tip switch is moved by the driver to adopt the tensioning position, the control unit increases a nominal value of the actuating force of the parking brake. By actuating the tip switch, the driver is thus able to determine which actuating force is used to actuate the parking brake.

  • Patent number: 6662906
    Abstract: With electromechanically or electromotively operated brakes, adjusting a clearance presents a problem because with this type of brakes self-actuating reset means of the type provided for hydraulic brakes cannot be used. For adjustment, a neutral position of the actuator must first be determined in which at least one of the friction linings is in close proximity. To this end, the present invention provides for the change in the actuator current (IAkt) and the change in the actuator position (&phgr;Akt) to be evaluated so as to determine the contact.

  • Patent number: 6626271
    Abstract: The present invention relates to an electrically operable brake system and a method for its actuation. The brake system and the method are characterized in that the service brake system can be activated by two brake operating devices which are operable by the driver independently of each other. The main advantage which results is that upon failure of a brake operating device which is e.g. configured as a brake pedal module, braking of the vehicle can be achieved by means of the service brake system by way of the second brake operating device. The additional functions intended for the service brake system, such as ABS, TCS, driving dynamics control, brake assist system, etc., may then be implemented, if so desired. The redundant design of the actuation for the service brake permits achieving a high degree of operational safety because full braking functions can be maintained even in case of emergency braking.

  • Patent number: 6550871
    Abstract: A method and system for controlling a brake for motor vehicles. The present invention relates to a method as well as a system for controlling a brake for motor vehicles, which can be electromechanically actuated by means of an actuator, consisting of an electric motor as well as a drive mechanism positioned downstream of the electric motor. In order to be able to increase motor speed under certain operating conditions, i.e. according to demand, without reducing the available torque, the invention provides for the slope of the speed-torque characteristic curve of the electric motor (4) to be modified by weakening components of the electromagnetic field of said electric motor (4), which affect the dynamics of same, in such a way that a higher speed (&ohgr;′1) is obtained at the same torque (M1).
