| 抄録（英） | Ability to accelerating a passenger car at rapid depressed an accelerator pedal is one of main conditions of the active safety. This situation takes place during overtaking process, which is caused by driving force deficiency from engine and powertrain mechanical inertia. It has negative influence on overtaking process and also on driving comfort. This phenomenon mainly come from accumulation of mechanical energy of powertrain. It leads to driving force drop as a result of energy accumulation in first phase of the overtaking process, and in the next phase leads to arising excessive driving force on wheels. In power transmission systems with constant power supply e.g. CVTs characterised by a large differentiation of kinematic transmission, the investigated issue plays an important role. In order to secure a prompt response of such transmission systems a variety of control strategies is proposed. Particular attention is devoted to transmission systems with zero inertia, which apply an supplementary power source (device applying inertia or electrical motor) to assist the engine in accelerating in the transition phase. Due to the large complexity of those systems an alternative construction is proposed, one which does not apply a hybrid drive. The compensation of mechanical inertia secured by a short-term engine supercharging. This supercharging is performed with the aid of compressed air chamber. 翻訳 |
