Abstract: A device is used for supplying fuel to a burner in a fuel cell system with a reformer. The fuel comprises a materials flow of a reformate gas, which materials flow is depleted of hydrogen, and a materials flow of a compound which comprises carbon and hydrogen. According to the invention, the device comprises at least one nozzle means in which the two materials flows can be mixed together. At least one of the materials flows is controllable as far as its through-flow is concerned.

Abstract: In order to optimize control of drive slip, the torque demand of the drive is determined continuously taking into account the interfering torques acting on the vehicle, and the drive torque is reduced to this torque demand when instability occurs.

Abstract: The invention relates to a method for filtering out disturbances in the form of short term wheel acceleration signals when the wheel exhibits an overall deceleration, so that a more accurate deceleration signal can be used for control of drive slippage.Wheel speed v is measured at intervals T.sub.A and speed changes for each interval are determined. When a change is negative or zero following a positive change in a previous interval, the wheel speed is stored as a maximum speed v.sub.max while v continues to be measured and a counter determines the period of time .DELTA.t between the occurrence of v.sub.max and the instantaneous value v. Beginning at a predetermined filtering time .DELTA.T after storing v.sub.max, a quotient .DELTA.v/.DELTA.t representing the filtered slope of the value v is determined and used as a control variable to regulate wheel slippage.

Abstract: In the anti-lock control system described, the beginning of control is made more difficult in order to screen out disturbances. This is achieved by forming the sum or the average value of the slip values of at least the wheels of the front axle and, for triggering control, entering this sum or this average value into the instability criterion.

Abstract: A reference speed value which corresponds to the vehicle speed is derived from the speeds of the non-driven wheels. If the wheel speed signals exceed this reference value by a threshold slippage value .lambda., the brakes are applied and/or the engine torque is reduced. In addition to the factor of the vehicle speed, this slippage value .lambda. includes a constant value and an acceleration-specific factor. Further, it is also possible to allow for the pedal position.

Abstract: In a drive-slip control system, if the unfiltered wheel speed of a non-driven wheel is below the filtered reference speed by a predetermined amount, the reference speed is increased in steps. This prevents the control system from being triggered erroneously when a non-driven wheel is retarded by snow, water etc.

Abstract: Vehicle speed is measured during slip-free travel of the wheels and compared with the wheel speeds to determine correction values which correct for different wheel diameters. The correction values are used to continuously correct the wheel speeds.

Abstract: An anti-locking brake control system for a motor vehicle comprises wheel speed sensors for determining the speeds of the individual vehicle wheels, an evaluation circuit which receives the wheels speed signals and generates brake pressure control signals, and a brake pressure control device responsive to the brake pressure control signals for controlling the brake pressure applied to the wheels. The evaluation (processing) circuit includes a brake pressure control unit which operates in such a manner that, after brake pressure decays, the brake pressure is first increased in a timed build-up with reference to the brake pressure build-up in a preceding control cycle, and thereafter the brake pressure is further increased by a sequence of pulses until an instability is again detected.
