  • Publication number: 20200200493
    Abstract: A heat exchanger including a manifold body having at least one fluid passage, a cooling passage section having a body including a set of fluid passages extending through at least a portion of the cooling passage section, and a weld joint fluidly sealing the manifold body and the cooling passage such that at least one of the set of fluid passages is fluidly coupled to the at least one fluid passage of the manifold body and methods of forming.

  • Patent number: 8833867
    Abstract: In a method and a device for the control of a vehicle brake system, the setpoint values for each wheel are corrected based on the difference between brake pressures in at least one wheel brake of two different brake circuits.

  • Patent number: 7062369
    Abstract: A method and a device for determining a characteristic value of a wheel brake are described. The characteristic value here is the brake characteristic value, which representing the relationship between the braking torque or braking force and the brake pressure of a wheel brake operated hydraulically. This brake characteristic value is determined individually for each wheel by calculations based on wheel-specific variables.

  • Patent number: 7011379
    Abstract: A control circuit for a controllable electric solenoid valve of a brake system of a motor vehicle is described, in which the actual values of a controlled variable (f(t)), e.g., the vehicle deceleration, a wheel slip, a driving speed, an angle of rotation or the like are returned to a predetermined tolerance band. The actual value of the controlled variable is measured continuously and compared with the predetermined tolerance band, which is stored in an EEPROM, for example. If the actual value of the controlled variable leaves the predetermined tolerance band (22), a correction device (15) intervenes and returns the actual value to the predetermined tolerance band by increasing or decreasing the trigger current for the solenoid valve (1).

  • Patent number: 6504699
    Abstract: A method and a device are proposed for driving a solenoid valve that has stroke ranges of a stable equilibrium of forces and stroke ranges of an unstable equilibrium of forces. For setting the predetermined differential pressure across the solenoid valve, a driving signal quantity is generated which is selected such that the stroke ranges of an unstable equilibrium of forces are avoided or the dwell time of the solenoid valve in these ranges is reduced.

  • Patent number: 6311669
    Abstract: Pressure fluctuations occurring during two sequential injections (for example a pre-injection and a main injection) within a working cycle of a cylinder in a lead to the injector are taken into account with the aid of a correction term. A drive time of the injectors is determined with the aid of a corrected pressure so that a desired fuel quantity is injected. The correction term is determined with the aid of a least-squares estimator that estimates the injection pressure at the nozzle of injector as a function of the geometrical data of the system, in particular a length of the lead from the rail to the injector and physical boundary conditions, for example a fuel temperature.
