丰田智能电子节气门控制系统(ETCS-i)与传统的普通节气门相比有许多优越之处,主要表现在: 1.节气门开度的控制。在普通节气门体上,节气门的开度由加速踏板的踏下量来控制;而ETCS-i根据发动机ECU对应于驾驶状况来计算出最佳的节气门开度,并利用气门控制电机来控制节气门的开度。 2.整个控制系统结构简化。ETCS-i同时控制ISC系统、巡航控制系统和VSC系统,使车辆结构大大简化。
Toyota Intelligent Electronic Throttle Control System (ETCS-i) compared with the conventional common throttle has many advantages, mainly in: 1. Throttle opening control. In a normal throttle body, the throttle opening is controlled by the amount of depression of the accelerator pedal. The ETCS-i calculates the optimal throttle opening according to the driving situation of the engine ECU and uses the valve control motor Control throttle opening. 2. The whole control system structure is simplified. The ETCS-i controls both the ISC system, the cruise control system and the VSC system, which greatly simplifies the vehicle structure.
