Problems solved by technology

However, the use of automatic transmissions brought corresponding improvements and also produced some negative effects: ①The system is highly complex, and its reliability is correspondingly reduced compared with simple mechanical transmissions; ②The transmission efficiency is reduced and energy consumption is increased; ③The system Increased weight reduces drive-to-weight ratio
Some other methods, such as the use of automatic clutches (electric, hydraulic and pneumatic), electronically controlled hand brakes, etc., have improved driving comfort in some parts and reduced the burden on the driver, but they have not combined the traditional mechanical transmission. Advantages for further excavation

Abstract

The invention relates to a car-driver auxiliary means, especially to a driving means of car-stopping and car-starting which comprises: car stops when stepping coupler and footbrake; car waits for start when loosing coupler and footbrake; car starts when shifting start grand, positing the grade at start grand, stepping choker. The car-driver auxiliary system is formed by braking force maintaining mold, coupler controlling mold, choker controlling mold and controller. It adopts coupler controlling mold and braking force maintaining mold as checker, inlet controller as core controlling unit, and braking sensor and choker sensor as signal sensor.

Description

technical field [0001] The invention relates to an automobile driving assistance method and its system, in particular to the automobile driving assistance method and its system used in short-term parking and starting of automobiles. Background technique [0002] The coupling of the clutch, the maintenance of the braking force and the acceleration information in the traditional mechanical transmission (MT) in the car are three power or information flows that are not related to each other and require driver intervention. ) To achieve a good driving effect, the driver needs to comprehensively optimize and adjust the above three power processes. Without rich driving experience and a good grasp of the vehicle, it is often difficult to achieve good results. [0003] For the driver, some operations when the vehicle is running smoothly are not cumbersome, and the physical burden is not great. However, when the vehicle is running in the city, when it encounters road conditions with ...
