摘要
A method for controlling and regulating a transmission brake of an automatic transmission designed as a gear reduction unit in which the rotation speed of a countershaft of the gearbox can be decelerated in an upshift such that it corresponds to the synchronized rotation speed or comes close to it up to a predetermined distance during an upshift operation. The brake gradient of the countershaft rotation speed or the gear input rotation speed as well as the gear output shaft rotation speed is taken into consideration for the control and regulation of the gearbox brake. The gradient of the gear output shaft rotation speed is analyzed to control and regulate operation of the bearbox brake to improve the upshift, operations.
