Detailed Description

In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that, in the case of no conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.

Fig. 1 is a flowchart of a control method for an automatic transmission according to an embodiment of the present disclosure, and this embodiment is applicable to a working condition that a vehicle is on a slope and stops and starts again. The method may be performed by an automatic transmission control device, which may be implemented in software and/or hardware, which may be configured in an electronic device, such as a transmission controller.

As shown in fig. 1, the method may specifically include:

s110, acquiring first running information of the vehicle; the first operation information includes information on a rate of change of a rotation speed of an output shaft of a transmission in the vehicle.

The first operating information is information that can subsequently be used to determine the torque increase value. In practice, what kind of physical quantity is specifically used as the first operation information, and the application does not limit this. Illustratively, the first operation information includes transmission output shaft speed change rate information in the vehicle.

In practice, an output shaft rotation speed sensor is arranged at the output shaft of the gearbox, and the output shaft rotation speed sensor periodically collects the rotation speed of the output shaft of the gearbox at preset time intervals. The information of the change rate of the rotating speed of the output shaft of the gearbox refers to the ratio of the change amount of the rotating speed of the output shaft acquired by the output shaft rotating speed sensor twice to the time interval of the two acquisitions. Illustratively, if at t ₁ At any moment, the collected rotating speed of the output shaft of the gearbox is n ₁ (ii) a At t ₂ At any moment, the collected rotating speed of the output shaft of the gearbox is n ₂ The change rate f of the rotating speed of the output shaft of the gearbox is obtained based on the following formula:

。

it should be noted that, in practice,

，t ₀ the time interval is the time interval between two adjacent times of the output shaft speed sensor for collecting the rotating speed of the output shaft of the gearbox. k is a positive integer greater than or equal to 1.

The larger the change rate of the rotating speed of the output shaft of the gearbox is, the more serious the current situation that the vehicle rolls is, the larger the difference between the component acting force of gravity on the vehicle downwards along a slope and the traction force of the engine on the vehicle upwards is, namely the larger the output power of the engine needs to be increased.

In another embodiment, the first operational information further comprises at least one of: weight information of the vehicle and gradient information of a slope on which the vehicle is located. In practice, the weight information of the vehicle can be derived on the basis of the traction experienced by the vehicle and the acceleration of the vehicle. The information on the gradient of the slope on which the vehicle is located can be acquired based on a gradient sensor installed in the vehicle.

S120, if the vehicle is in a slope state; based on the first operational information, a torque increase value is determined.

The state of rolling is a state in which the power of the vehicle is insufficient to maintain the vehicle moving in the direction of an uphill. In practice, the hill state includes two cases: one situation is that the vehicle head faces the top of a slope, and a driver wants to control the vehicle to advance along the direction pointing to the top of the slope but moves along the direction pointing to the bottom of the slope; in another situation, the vehicle head faces the bottom of a slope, and a driver wants to control the vehicle to reverse in the direction pointing to the top of the slope, but the vehicle moves in the direction pointing to the bottom of the slope.

The torque increasing value is used for indicating a torque value which needs to be increased again on the basis of the current output torque value of the gearbox.

There are various methods for implementing this step, and this application does not limit this. Illustratively, a functional relationship between the first operation information and the torque-increasing value can be constructed in advance, and the functional relationship takes the first operation information as an independent variable and the torque-increasing value as a dependent variable; when this step is executed, the first operation information obtained in S110 is brought into the functional relationship, and a torque increase value is obtained. Illustratively, the corresponding relation between the change rate of the rotating speed of the output shaft of the gearbox and the torque increasing value is preset, and when the step is executed, the torque increasing value is determined based on the current information of the change rate of the rotating speed of the output shaft of the gearbox in the vehicle and the corresponding relation between the change rate of the rotating speed of the output shaft of the gearbox and the torque increasing value.

In another embodiment, if the first operation information includes information on a rate of change of a rotation speed of an output shaft of a transmission in the vehicle, information on a weight of the vehicle, and information on a gradient of a slope on which the vehicle is located, the method includes: determining a first torque value based on the information about the rate of change of the rotational speed of the output shaft of the gearbox; determining a second torque value based on the weight information of the vehicle; determining a third torque value based on the grade information of the slope on which the vehicle is located; a torque increase value is determined based on the first torque value, the second torque value, and the third torque value. The essence of the arrangement is that when the torque increasing value is determined, the influence of the change rate information of the output shaft of the gearbox in the vehicle, the weight information of the vehicle and the slope information of the slope on which the vehicle is positioned on the slope is comprehensively considered, a proper torque increasing value is obtained, and the slope slipping prevention effect of the vehicle is improved.

Further, there are various specific implementation methods for determining the torque increase value based on the first torque value, the second torque value, and the third torque value, and the present application does not limit this method, and corresponding weights may be set for the first torque value, the second torque value, and the third torque value, respectively, and the torque increase value is determined by combining the first torque value, the weight of the first torque value, the second torque value, the weight of the third torque value, and the weight of the third torque value when determining the torque increase value.

Illustratively, the weight of the first torque value, the weight of the second torque value, and the weight of the third torque value are the same, in which case optionally "determining the torque increase value based on the first torque value, the second torque value, and the third torque value" comprises: and taking the sum of the first torque value, the second torque value and the third torque value as a torque increasing value. On one hand, the method for calculating the torque increasing value is simple and easy to realize; on the other hand, the risk sharing can be realized, the situation that the torque-increasing value is determined by excessively depending on a certain influence factor, the acquisition result of the physical quantity corresponding to the influence factor is wrong due to sensor faults and the like, and the obtained torque-increasing value has large deviation to cause the occurrence of the adverse effect of vehicle out of control is avoided.

S130, outputting a torque increasing instruction to a transmission case in the vehicle, wherein the torque increasing instruction comprises a torque increasing value; the transmission is used to perform an operation corresponding to the torque-up command to increase the output power of the engine in the vehicle.

The increased output of the engine increases the traction force to which the vehicle is subjected.

According to the technical scheme, the first running information of the vehicle is acquired; the first operation information includes information on a rate of change of a rotation speed of an output shaft of a transmission in the vehicle; if the vehicle is in a slope slipping state; determining a torque increase value based on the first operation information; outputting a torque increasing instruction to a gearbox in the vehicle, wherein the torque increasing instruction comprises a torque increasing value; the gearbox is used for executing operation corresponding to the torque increasing instruction so as to increase the output power of an engine in the vehicle and further increase the traction force borne by the vehicle, so that the upward traction force along the slope is greater than the downward component force of gravity along the slope, the purpose of preventing the vehicle from sliding down the slope is achieved, the abrasion of parts of the vehicle is reduced, and the safety of a user when the user drives the vehicle is improved.

In addition to the above solutions, before S120, optionally, the method further includes determining whether the vehicle is in a downhill state.

In practice, there are various methods for "judging whether the vehicle is in a slope slipping state", and this application does not do so, and exemplarily obtains second operation information of the vehicle; and judging whether the vehicle is in a slope slipping state or not based on the second operation information. The second operation information is information that can be used to determine whether the vehicle is in a state of rolling away.

In practice, which information is specifically used as the second operation information is not limited in this application. It should be emphasized that, when determining what the second operation information is, on one hand, it is required to ensure that the control intention of the user on the vehicle is known, and on the other hand, it is required to specify the current vehicle state, so that whether the vehicle is in a slope slipping state can be accurately determined. The second operation information includes information about the current gear of the gearbox and information about the rotational speed of the output shaft of the gearbox. The current gear information of the gearbox represents the control intention of a user on the vehicle, and the rotating speed information of the output shaft of the gearbox represents the current state of the vehicle.

In one embodiment, determining whether the vehicle is in a downhill state based on the second operation information includes: if the current gear is a forward gear, the rotating speed of an output shaft of the gearbox is a negative value, and the vehicle is in a slope slipping state; if the current gear is a forward gear, the rotating speed of an output shaft of the gearbox is a positive value, and the vehicle is not in a slope slipping state; if the current gear is reverse gear, the rotating speed of the output shaft of the gearbox is negative, and the vehicle is not in a slope slipping state; if the current gear is the reverse gear, the rotating speed of the output shaft of the gearbox is a positive value, and the vehicle is in a slope slipping state.

The current gear is a forward gear, the rotating speed of an output shaft of the gearbox is a negative value, the corresponding vehicle head faces the top of a slope, and a driver wants to control the vehicle to advance along the direction pointing to the top of the slope but moves along the direction pointing to the bottom of the slope, so that the vehicle is in a slope slipping state. When the current gear is a reverse gear, the rotating speed of an output shaft of the gearbox is a positive value, a corresponding vehicle head faces to the bottom of a slope, and a driver wants to control the vehicle to back up along the direction pointing to the top of the slope but the vehicle moves along the direction pointing to the bottom of the slope, so that the vehicle is in a slope slipping state.

In another embodiment, the second operation information further includes a braking state of the vehicle, information of a slope collected by a slope sensor in the vehicle, and the like, so that the accuracy of the judgment result of whether the vehicle is in a slip state can be further improved.

In a vehicle, various sensors (including a gearbox output shaft rotating speed sensor, a gradient sensor, an acceleration sensor and the like), a gearbox and a gearbox controller are connected with a CAN network. The gearbox controller acquires rotating speed information acquired by a rotating speed sensor of an output shaft of the gearbox, gradient information acquired by a gradient sensor and acceleration information acquired by an acceleration sensor through a CAN network, and acquires current gear information of the gearbox from interaction information of the gearbox controller and the gearbox. And the gearbox controller judges that the current vehicle is in a slope slipping state based on the current gear information of the gearbox and the rotating speed information (which is a positive value or a negative value) of the output shaft of the gearbox. If the current vehicle is in a slope state, the gearbox controller obtains the current change rate information of the rotating speed of the output shaft of the gearbox based on the rotating speed information collected by the rotating speed sensor of the output shaft of the gearbox; a first torque value corresponding to a current rate of change of transmission output shaft speed is then determined. Table 1 shows the correspondence between the change rate of the rotational speed of the output shaft of the transmission and the first torque value. Illustratively, a first torque value that currently corresponds to the rate of change of the transmission output shaft speed is determined by a look-up table (e.g., table 1). The gearbox controller also determines the current weight information of the vehicle based on the acceleration information acquired by the acceleration sensor and the current traction force; and determining a second torque value corresponding to the current weight information. Table 2 shows the correspondence between the weight information and the second torque value. Illustratively, the second torque value corresponding to the current weight information is determined by looking up a table (e.g., table 2). The transmission controller also determines a third torque value corresponding to the grade information collected by the current grade sensor. Table 3 shows the correspondence between the gradient information and the third torque value. Illustratively, a third torque value corresponding to the grade information collected by the current grade sensor is determined by looking up a table (e.g., table 3).
