Title:
自動車のドライブトレインの変速比の決定方法
Document Type and Number:
Japanese Patent JP2008509362
Kind Code:
A
Abstract:
A method for determining a gear transmission ratio in the drivetrain of a motor vehicle having an engine, a clutch and a variable speed gearbox. A gear transmission ratio between the engine and the variable speed gearbox being determined from the rotational speed of the output shaft of the engine and the rotational speed of the output shaft of the variable speed gearbox. A method having additional steps of determining an amount of the current speed of the motor vehicle and processing the value of the current rotational speed of the output shaft of the variable speed gearbox and the value of the current speed of the motor vehicle using a processing unit so that the gear transmission ratio of the vehicle components of the drivetrain located downstream of the variable speed gearbox is determined.
