Engine throttle control with varying control constants |
摘要 |
ECU performs a feedback control on a d.c. motor by a PID feedback control thereby to reduce errors between an actual throttle opening and a command throttle opening. PID control constants Kp, Ti and Td in the PID control are determined in accordance with operating conditions of a vehicle, such as engine idle speed control condition, vehicle traction control condition, vehicle cruise control condition and the like.
