Description

Intelligent clutch based on difference ratio self-balancing method
Technical Field
The invention relates to a traction control part in the field of vehicle intelligent control, in particular to an intelligent clutch based on a differential ratio self-balancing method.
Background
With the improvement of living standard of people, more and more people buy vehicles as transportation tools. The existing small vehicles are generally divided into manual gears and automatic gears, and although the existing automatic gear vehicles are simple to operate and easy to learn, the existing automatic gear vehicles are expensive, high in maintenance cost and relatively high in oil consumption, so that the existing manual gears still occupy a large market, and especially taxies are generally manual gear vehicles.
The traditional manual gear shifting vehicle needs to continuously step on the clutch during gear shifting, and particularly needs to use the clutch to control the vehicle to run at a low speed during traffic jam, so that the clutch is more frequently stepped on, and heavy physical burden is brought to a driver.
Patent No. 201310560730.2 discloses an automatic clutch suitable for a manual transmission vehicle, which is based on the principle that "if the actual speed of the vehicle engine in the gear is greater than or equal to the lowest speed of the standard speed of the vehicle engine in the gear, the clutch is completely closed, otherwise, the cpu controls the clutch to be in a half-clutch state" and the description in the description section of the specification takes the above 1-gear of a certain vehicle type as an example, assuming that the actual gear is 1-gear, if the speed of the engine is greater than or equal to 700 rpm, the clutch is completely closed, otherwise, the clutch is in a half-clutch state ", it can be known from the patent description that the clutch is completely closed as long as the speed is greater than 700 rpm (different from vehicle type), and the actual speed is also completely closed as long as the actual speed is greater than 3000 rpm, which is obviously unreasonable, for example, if the vehicle is at a standstill at a speed slightly above 700 rpm, the clutch will tend to stall if the clutch is fully engaged when the vehicle needs to be started. For another example, if the vehicle is in a fast downhill state, after the driver slides for a certain distance in a neutral gear, the vehicle speed is found to be higher and higher, the engine brake is needed to be used soon, and then the gear is engaged, but the rotating speed is lower than the lowest rotating speed of the standard rotating speed of the gear, so that the clutch plate is in a half-clutch state, and the risk of abrasion of the clutch plate and even brake failure is caused.
It is known that the clutch is not worn when in a completely disengaged or completely engaged state, and the wear is most severe when the clutch is in a half-clutch state, especially at high rotational speeds, so how to reduce the half-clutch time is particularly important for prolonging the life of the clutch.

Detailed Description
In order to clearly illustrate the technical features of the present invention, the present invention will be described in detail by the following embodiments.
An intelligent clutch based on a differential ratio self-balancing method comprises the following steps: the system comprises a processing module, a gear sensor, a vehicle speed sensor, a rotating speed sensor and a clutch driving module;
the gear sensor is connected with the processing module;
the vehicle speed sensor is connected with the processing module;
the rotating speed sensor is connected with the processing module;
the clutch driving module is connected with the processing module;
the processing module acquires gear information of the vehicle through the gear sensor;
the processing module acquires the speed information of the vehicle through the vehicle speed sensor;
the processing module acquires the rotating speed information of the vehicle through the rotating speed sensor;
the processing module controls the action of the vehicle clutch through the clutch driving module;
the processing module controls the action of the clutch according to the following conditions:
when the processing module detects that the gear lever moves out of a standard gear range, the processing module controls the clutch driving module to completely separate the clutch, the standard gear range is pre-stored in the processing module in advance, because the gear lever has a movable gap in the gear, when the gear lever is determined to be in the gear range in the movable gap range, if the gear lever exceeds the gear range, the gear lever is determined to be moved out;
when the processing module detects that the gear lever is in a neutral gear, the processing module controls the clutch driving module to compound the clutch, and in order to reduce the load of a release bearing, the clutch is completely compounded when the gear lever is in the neutral gear, so please know that the neutral gear is not immediately compounded but delayed a little in practical application, for example, the gear is necessarily passed through the neutral gear when the gear is shifted from a third gear to a fourth gear, so the neutral gear is shifted into the fourth gear, and the neutral gear is not compounded, which can be understood by general technicians, and the delay time is generally 0.5 s;
when the processing module detects that the gear lever is a driving gear, the processing module calculates a difference value A by using the gear reduction ratio N, the vehicle rotating speed R and the vehicle speed V, the composite speed of the clutch is faster when the difference value A is larger, and the composite speed of the clutch is slower when the difference value A is smaller, and the calculation method of the difference value A is as follows:
the difference A = the rotation speed R-the vehicle speed V-the gear reduction ratio N,
The difference A = the rotating speed R/the gear reduction ratio N-vehicle speed V
In one of the two terms, the two calculation methods have the same effect because the reduction ratio N = the rotation speed R/the vehicle speed V.
The calculation result of the difference value A can be positive, zero and negative, the clutch compounding speed is completely determined by the difference value A, and the larger the value A is, the faster the clutch compounding speed is.
An intelligent clutch based on a differential ratio self-balancing method comprises the following steps: a brake sensor and a prompt module;
the brake sensor is connected with the processing module;
the prompt module is connected with the processing module;
the processing module acquires a brake signal of the vehicle through the brake sensor;
the prompting module sends out prompting information through the prompting module;
the processing module also controls the clutch action and prompt module according to the following conditions:
when the clutch composite post-processing module detects that the rotating speed of the vehicle is lower than the threshold B and the vehicle is braked, the processing module controls the clutch driving module to half-clutch the clutch, so that the phenomenon that the vehicle is flameout due to the fact that the rotating speed of an engine is too low due to braking of a driver when the gear of the vehicle is not in a neutral gear can be avoided;
when the speed of the vehicle exceeds a threshold value C and the gear is shifted from a forward gear to a reverse gear, the processing module controls the clutch driving module to keep the clutch completely separated and send out reminding information, for example, if the speed of the vehicle exceeds 10 KM/hour at the moment, the gear is shifted from the forward gear to a reverse gear after being shifted out, the situation that the vehicle is always in the forward gear at the moment is shown, so that a driver operates the vehicle by mistake when the reverse gear is shifted, the clutch is kept in a separated state, the reminding information is sent out to remind the driver of wrong operation, and if the composite clutch causes serious damage to a vehicle engine, a gearbox and the clutch at the moment;
when the processing module detects that the gear is not in the neutral gear after the starting, the processing module controls the prompting module to send out prompting information and completely separate the clutch, and if a driver inserts a key into a vehicle to be ignited (the vehicle is generally electrified before ignition), the device of the invention detects that the gear is not in the neutral gear, the prompting module immediately sends out the prompting information and completely separates the clutch to prevent the driver from igniting in a gear-off mode.
An intelligent clutch based on a differential ratio self-balancing method comprises the following steps: the gear sensors are correlation type distance sensors, and the number of the sensors is at least 2 groups.
An intelligent clutch based on a differential ratio self-balancing method comprises the following steps: the opposite-type distance sensor is a split type ultrasonic sensor, one of the transmitting probe and the receiving probe is fixed on the stop lever, and the other one is fixed on the vehicle body.

It is obvious that the determination of the gears is determined by distance, for example, the distance coordinates of each gear are prestored in the processing module, and the gear determination is performed by real-time gear rod coordinates when the processing is performed.
Referring to figures 3 and 4 of the drawings,
an intelligent clutch based on a differential ratio self-balancing method comprises the following steps: the clutch driving module comprises a steel wire connecting rod 1, a steel wire 2, a groove wheel 3, a groove wheel base 4, a steel wire sleeve 5, a winding wheel group 6, a heightening plate 7 and a motor 9;

The simulation assumes that a vehicle is started, after a driver shifts a gear from a neutral gear, the processing module controls the clutch driving module to completely separate the clutch, the gear is shifted into a first gear, the rotating speed is 700 revolutions per minute, the difference A = the rotating speed R-the vehicle speed V is the gear reduction ratio N, the vehicle speed is zero due to the fact that the vehicle is stationary, the difference A =700, the processing module controls the clutch driving module to compound the clutch at a speed corresponding to 700, if the rotating speed of the vehicle is not 700 but 2000, the clutch is compounded at a speed corresponding to 2000, the compounding speed is faster simply when the rotating speed is larger than A, an automatic balancing process is provided in the whole process, and when the clutch is quickly compounded at a speed corresponding to 2000, the rotating speed is reduced when the engine meets resistance after reaching a combination point, the composite speed of the clutch is thus slowed down, so that this composite speed is automatically balanced.
If a vehicle is on a downhill road, a driver performs downshift operation at the moment and intends to use an engine for braking, and the driver may step on a brake pedal at the moment, so that the engine speed is generally about 700 revolutions at an idle speed after the clutch is completely disengaged, and after the gear is engaged, the clutch is firstly compounded at a speed corresponding to the 700 revolutions, and then the engine speed is driven to rise due to the fact that the vehicle speed is high, so that the speed of the compound clutch is increased, the effect of quickly braking the compound clutch is achieved, and the point is also that the braking is balanced.
The invention indicates that the opposite-emitting ultrasonic wave can be used as a gear sensor, and other gear sensors, such as a Hall angle sensor, a resistance angle sensor, an encoder and the like, can also be used in practical application, and the final result is to determine the coordinate position of the gear without departing from the core idea of the invention.
Although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the present invention, which is to be construed as limited by the claims.
