  • Patent number: 10427667
    Abstract: The invention concerns a method for automatically controlling a motor vehicle (10) for switching from a “normal” mode to a “freewheel” mode, the vehicle (10) comprising an engine (12) capable of providing engine torque to drive wheels (14) via an automatically controlled clutch device (18) that comprises a drive shaft (15) and a driven shaft (16). A transition step (E1) is interposed chronologically between the “normal” mode and the “freewheel mode” during which the engine (12) is automatically controlled in such a way that the driven shaft (16) and the drive shaft (15) turn at the same speed without transmitting torque to the drive wheels (14).

  • Patent number: 10270373
    Abstract: A method for pulse-modulated current control of an inductive load current. A first operating mode is implemented when a change in current setpoint value is effected. An initial duty cycle of the pulse modulation is determined and used to operate the inductive load in a second operating mode. In the first operating mode, a switching state of at least one switching element is set depending on whether a current setpoint value of the load current is higher or lower than a current setpoint value of a directly preceding cycle. The switching state is retained until a current limit value is reached and then switched over. The switching state of the switching element is switched over multiple times to generate a prescribed number of periods, and the duty cycle of the pulse modulation is determined based on at least a portion of the prescribed number of periods.

  • Patent number: 8704508
    Abstract: Method in which the current is measured inside an integrated PWM control circuit using at least one A/D converter which is likewise integrated in the circuit is described. The PWM controller is provided for the purpose of driving inductive loads and is arranged, in particular, in an electronic circuit of an electronic controller for a motor vehicle braking system. Before determining the actual current of the PWM controller, which is determined using the at least one A/D converter, the current is smoothed using a low-pass filter. A circuit arrangement for carrying out the above method and its use in electronic motor vehicle control systems is also described herein.

  • Patent number: 8664936
    Abstract: The invention relates to an electronic motor vehicle control system having at least one valve actuating circuit which controls a load current by means of pulse width modulation. The actuating circuit has at least one electronic current measuring circuit which has at least one measurement path with at least one analog/digital converter. The analog/digital converts an analog measurement signal of the load current into a digital measurement signal of the load current and is actuated or designed in such a way as to carry out a plurality of current measurements per PWM period. The at least one measurement path of the current measurement circuit has a signal conservation circuit which provides the analog measurement signal of the load current substantially unchanged, and independent of the actual load current, for at least a defined hold time (toff->on, ton->off).
