  • Publication number: 20250115229
    Abstract: A brake system structure for a vehicle, preferably a brake-by-wire system, in which detection devices and conversion devices for a brake request are mechanically decoupled from one another. The brake system structure includes: a first brake system for providing a brake function, the first brake system being configured to be autonomous and having a first power supply; a second brake system for providing a first fallback level for the brake function, the second brake system being configured to be autonomous and having a second power supply; and a third brake system for providing a second fallback level for the brake function, in particular by regenerative deceleration. A third power supply is provided at least for the first brake system.

  • Patent number: 10358030
    Abstract: A method for operating a drivetrain for a motor vehicle, said method includes: reducing a transmission torque transmitted between a primary drive axle operatively connected with a secondary drive axle of the motor vehicle via a clutch configured to allow adjustment of the transmission torque when determining at the secondary drive axle a wheel slip which exceeds a defined slip threshold value.

  • Patent number: 6513618
    Abstract: A power steering system for a motor vehicle comprising a hydraulic reaction device (11) by which reaction power is generated on the steering column of the vehicle, depending on the speed thereof. According to the invention, a accumulator (14) is provided on the line (13) connecting the reaction device (11). Said accumulator serves as a low-pass filter and decouples the reaction device from oscillations in pressure due to uneven road surfaces.
