Control of vehicle IC engine throttle position

摘要

The microcomputer computer control unit (10) has a reference value builder (20) that responds to inputs (22, 24, 26, 28) from sensors and devices that indicate accelerator pedal position, engine speed, gear position and road speed, etc. The reference is coupled to a limiter (40) and a comparator (44) that receives an input (46) that is the actual position of the throttle (5) as measured (48). Rate of change is determined (60) and is gated (64) through to the signal limiter to adjust the actuator value.
