Document Type and Number:
Japanese Patent JP2961275
Kind Code:
B2
Abstract:
In a hydraulic pressure control apparatus for an automatic transmission, a retarding control apparatus has a first retarding signal output for processing the engine output decreasing rate and outputting a corresponding retarding signal, the absorbed power of the engine upon retarder operation is sensed, and the pressure oil is regulated to a predetermined pressure wherein the predetermined pressure is modulated responsive to the absorbed power of the engine. A second retarding signal outputting outputs a retarding signal corresponding to braking operation and a switch changes over the connection to the retarder, upon detecting a braking operation, from the first retarding signal to the second retarding signal and vice versa. The shifting shock during operation of retarder is eliminated even under elevated hydraulic pressure during the retarder operation.
