Embodiment 1

[0026] The embodiment of the present invention uses a cable-type separated motor to drive the cable electronically controlled auxiliary braking system to realize automatic parking.

[0027] like figure 2 As shown, the electronically controlled auxiliary braking system of the motor-driven cable of the present invention consists of a mechanical automatic transmission controller (TCU) 100, a cable parking mechanism 22 mounted on the wheel, a cable 23, and a cable driven by a motor. The winch is composed of 24 integrations.

[0028] In this embodiment, the electric motor 24 is used to drive the hoisting device to replace manpower to control the tension and relaxation of the cable 23 .

[0029] When the vehicle starts uphill, the mechanical automatic transmission controller (TCU) 100 automatically controls the electric motor 24 to be tightened to different degrees to prevent the vehicle from walking backwards and allow free running. When the output torque of the engine 700 and t...

Embodiment 2

[0032] The embodiment of the present invention realizes automatic parking by using a pneumatically separated braking electronically controlled auxiliary braking system.

[0033] like image 3 As shown, the pneumatic braking electronically controlled auxiliary braking system of this embodiment consists of a mechanical automatic transmission controller (TCU) 100, an air pressure sensor 36, a cylinder 32, a solenoid valve 34, an air source tank 35 with an air pump, and a pipeline 33 composed of.

[0034]In this embodiment, a solenoid valve is used to control the pressure in the cylinder to realize the pressure closed-loop control of the friction plate's pressure on the wheel and the gas circuit fault diagnosis.

[0035] The air pressure is supplied by the air source tank 35 on the car. When starting uphill, the mechanical automatic transmission controller (TCU) 100 automatically controls the solenoid valve 34 to deflate in different degrees to prevent the car from walking backwa...

Embodiment 3

[0039] The embodiment of the present invention realizes automatic parking by using the hydraulic brake electric control auxiliary braking system.

[0040] like image 3 As shown, the pneumatic braking electronically controlled auxiliary braking system of this embodiment consists of a mechanical automatic transmission controller (TCU) 100, an oil pressure sensor 36, an oil cylinder 32, a solenoid valve 34, an oil source tank 35 with an oil pump, and a pipeline Composed of 33.

[0041] In this embodiment, a solenoid valve is used to control the pressure in the oil cylinder to realize the pressure closed-loop control of the friction plate's pressure on the wheel and the gas circuit fault diagnosis.

[0042] The oil pressure is supplied by the oil source tank 35 on the car. When starting uphill, the mechanical automatic transmission controller (TCU) 100 automatically controls the solenoid valve 34 to drain oil in different degrees to prevent the car from walking backwards and run...

Abstract

The invention discloses a mechanical automatic transmission control system with an ECB (Electric Control Automatic Brake device), which comprises an electric control auxiliary brake system with a motor driving guy cable and a pneumatic or hydraulic brake electric control auxiliary brake system controlled by a solenoid valve, wherein the electric control auxiliary brake system and the pneumatic or hydraulic brake electric control auxiliary brake system respectively comprise a mechanical automatic transmission control unit (TCU) (100). The TCU is an independent control unit or can be a control unit which is combined with the transmission or / and an engine control unit (ECU); and the mechanical automatic transmission control system is used for accurately controlling a tensile force of a motor of a driving guy cable winch integration (24) to a guy cable (23) during ramp way starting and parking, and further controlling a brake force to wheels (21) or can be used for controlling the pressure of the solenoid valve to the interior of an air cylinder or the interior of a hydraulic cylinder or the pressure of the solenoid valve to oil charging of an oil cylinder, and further controlling the brake force. The mechanical automatic transmission control system disclosed by the invention is suitable for controlling transmissions of various automobiles.

Description

[0001] technical field [0002] The invention relates to a mechanical automatic transmission control system with ECB, which belongs to the technical field of vehicle transmission control. Background technique [0003] Due to the advantages of low energy consumption, low emission, low cost and convenient driving, automatic mechanical transmission (AMT) has been accepted and loved by more and more users. AMT replaces the driver to automatically determine the shift time and automatically execute the shift. This is relatively close to the traditional hydraulic automatic transmission (AT). Since the AT has a parking self-locking device, there is a formal parking gear P on the joystick. When the driver puts the joystick to the P gear, the car power chain is locked and cannot move, even if the car is parked on a general slope. On, the car will not slide down. However, the mechanical gearbox (MT) itself does not have such a self-locking device, so the AMT evolved on the basis of ...
