Problems solved by technology

[0002] The current AT-based hybrid hydraulic control system has a complex structure and cumbersome control, resulting in high cost of the hydraulic system and frequent hydraulic failures
Moreover, the current AT-based hybrid power adopts the method of engaging the clutch after the motor or engine starts to reach a certain speed. Because of the energy loss in the clutch friction process, the economy is not ideal, and because the motor or engine starts to reach a certain speed Takes time, so there is a lag to start

Abstract

The invention discloses an automobile, an automatic transmission and a hybrid power hydraulic control system. The hybrid power hydraulic control system comprises a first reversing valve, a second reversing valve and a third reversing valve. The first reversing valve is provided with a first valve port, a second valve port, a third valve port, a fourth valve port, a fifth valve port and a sixth valve port. The second reversing valve is provided with a first connector, a second connector, a third connector, a fourth connector and a fifth connector. The second valve port is suitable for being communicated with a cooling lubricant passage of the hydraulic control system, the third valve port is respectively connected with the third connector and the third reversing valve, the fourth valve port is respectively connected with the third connector and the third reversing valve, the fourth connector is suitable for being connected with the cooling lubricant passage, and the fifth port is suitable for being connected with a shift executing component of the automatic transmission. A main oil pump is respectively connected with the first connector, the second connector and the third reversing valve. An auxiliary oil pump is respectively connected with the first valve port and the sixth valve port. An energy accumulator is connected with the fifth valve port, and a driving device is used for driving the auxiliary oil pump to work. The hybrid power hydraulic control system is simple in structure, easy to control, and capable of effectively solving the problem of slow start of the automobile.

Description

technical field [0001] The invention relates to the technical field of hybrid power hydraulic control, in particular to an automobile, an automatic transmission and a hybrid power hydraulic control system. Background technique [0002] The current AT-based hybrid hydraulic control system has a complex structure and cumbersome control, resulting in high cost of the hydraulic system and frequent hydraulic failures. Moreover, the current AT-based hybrid power adopts the method of engaging the clutch after the motor or engine starts to reach a certain speed. Because of the energy loss in the clutch friction process, the economy is not ideal, and because the motor or engine starts to reach a certain speed It takes a while, so there is a lag in startup. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. [0004] Therefore, an object of the present invention is to provide a hybrid hydraulic co...
