摘要:
An engine control system that regulates operating of an engine of a motor vehicle includes a first module that determines whether a throttle of the motor vehicle is closed and a second module that determines whether the engine is idling while a cruise control is active. A third module selectively inhibits an RPM-based idle speed control of the engine if the throttle is closed and the engine is idling while the cruise control is active.

A correction system and method for an electronic throttle control includes a generator module that generates a learned-correction value corresponding to a first air-learn index. The learned-correction value is used to compensate a throttle position. A correction module writes to a throttle position correction array with the learned-correction value when an air-learn value equals a predetermined stability threshold.

A buffer utilizing MOS devices for coupling a computer input data line and a computer output data line to a single input/output port is disclosed. The buffer receives a control signal generated by computer port control means at the beginning of any buffer cycle when data is to be accepted by the buffer.

A throttle area compensation system for use with an electronic throttle control of a vehicle includes a compensation datastore of compensation values indexed by pre-compensated throttle area. A compensation vector learning module receives a pre-compensated throttle area and at least one sensed vehicle condition, and informs the compensation datastore based on the pre-compensated throttle area and the sensed vehicle condition. A throttle area compensation module communicates with the compensation datastore, receives the pre-compensated throttle area, and determines a compensated throttle area based on the pre-compensated throttle area and a corresponding compensation value of the compensation data store.

A memory accessing method is described which is particularly useful with the Multibus where a dynamic memory is employed. When the memory is accessed without a refresh collision, a ready signal is generated before the acknowledgement signal. This saves considerable time since the time between the placement of the data on the bus and the CPU's sensing of the data is reduced.

A control system for regulating operation of a vehicle having a transmission driven by an engine during a cruise control mode includes a first module that determines an operating point of the vehicle and that compares the operating point to one of a shift line and a torque converter clutch (TCC) release line. A second module regulates a throttle of the engine to maintain the operating point a threshold distance from the one of the shift line and the TCC release line, when the operating point is at the threshold distance.
摘要:
An MOS digital computer incorporated on a single chip (monolithic structure) which includes a central processing unit (CPU), random-access memory (RAM), and a programmable read-only memory (PROM). A program counter is used to fetch instructions stored in the erasable PROM, and may also be used to fetch instructions from an external memory. The PROM may also be externally addressed for testing, or may be electrically isolated from the remainder of the computer to permit execution of external instructions for testing the CPU and RAM.
