Embodiment

[0021] Such as figure 1 As shown, this embodiment discloses a hybrid hydraulic control system, including an automatic transmission with a gear position control oil circuit. The gear control oil is supplied by the oil pump 1 in the automatic transmission, and the automatic transmission is also provided with a motor pump 41 for supplying oil to the gear control oil circuit and an accumulator for storing the hydraulic energy of the motor pump 41. Energy device 36.

[0022] The automatic transmission is provided with a secondary lubricating oil supply circuit with a larger oil supply when the engine is driven and a smaller oil supply when the motor is driven.

[0023] The automatic transmission is provided with a reverse clutch C3 and a second and fourth brake B2 for braking the second and fourth gears; The reversing valve 21 and the second and fourth gear brake control valves 22 connected with the reversing valve 21.

[0024] The gear position control oil circuit consists of a...

Abstract

The invention discloses a hybrid power hydraulic control system which comprises an automatic gear transmission with a gear control oil path. An oil pump in the automatic gear transmission supplies power to the gear control oil path. A motor pump used for supplying oil to the gear control oil path and an energy storage device used for storing hydraulic energy of the motor pump are further arranged on the automatic gear transmission. The system utilizes the energy storage device to store the hydraulic energy of the motor pump, can utilize the energy storage device to drive a clutch in the automatic gear transmission before a vehicle starts, prevents the clutch from generating sliding and friction effect and improves working efficiency of the vehicle. The hybrid power hydraulic control system is suitable for various hybrid power vehicles, improves working efficiency, and saves energy.

Description

technical field [0001] The invention relates to a vehicle control system, in particular to a hybrid power hydraulic control system. Background technique [0002] The power system of the existing hybrid vehicle adopts the original automatic transmission for power drive, and the gear position control oil is supplied by the oil pump in the automatic transmission. When the motor or engine reaches a certain speed, the oil pump can control the clutch and brake. When the action occurs, the clutch will slip to generate friction, so the energy loss in the starting process is relatively large, which is not conducive to improving the working efficiency of the hybrid vehicle. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hybrid power hydraulic control system, which can avoid the friction effect of the clutch when the vehicle starts, and improve the working efficiency of the vehicle. [0004] In order to solve the proble...
