Title: Throttle flap control arrangement for vehicle
Inventor: STREIB MARTIN DR
IPC: B60K28/06
Filed: 1994-04-02
Abstract: The engine throttle valve setting is controlled by a servo system which monitors the throttle pedal setting. The actual throttle setting is compared with the control setting and is adjusted accordingly. If the brakes are applied the throttle is automatically set to idling. The idling position is automatically updated from the start position when the ignition is first switched on. This allows the driver to select a different idling setting. During operation the system monitors the idling setting and resets it as required. If for example the throttle linkage has a temporary blockage then an appropriate idling setting is set, on release of the blockage the idling setting is corrected.

IPC: H04L25/03
Filed: 1995-07-18
Abstract: A process is disclosed for detecting zero crossings of data signals by means of a comparator. In order to detect zero crossings in an accurate manner even when data signals (D) are distorted during transmission through a system with filtering characteristics, an auxiliary voltage (Uh) that corresponds to half the difference between the detected maximum and minimum values of the data signals (D) is generated. By comparing a reference value (Ub) proportional to the auxiliary voltage (Uh) with the momentary value of the data signal (D), an additional voltage (Uz) is formed to which the auxiliary voltage (Uh) is added to form a total voltage (Us). The total voltage (Us) is used to form the reference voltage (Uref5) of the comparator (5).
