Title:
車両の変速装置のシフト制御のシステム及び方法
Document Type and Number:
Japanese Patent JP5351154
Kind Code:
B2
Abstract:
Systems and methods for shift control for vehicular transmission. A transmission may shift gears at designated transmission shift points. When the slope of the road grade encountered by a vehicle changes, the transmission shift points may be altered to provide better vehicle performance. According to one embodiment, road slope may be calculated based upon vehicle acceleration and acceleration caused by pedal depression. In such an embodiment, brake indication may be calculated from the same road slope calculation without the use of a brake signal switch. If brake application is indicated by the road slope calculation, transmission shifting may be adjusted to prevent poor vehicle performance.
