Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a torque control method and device, a storage medium, a transmission controller and a vehicle. Background Art

[0002] At present, some automatic transmission fuel vehicles or multi-speed hybrid vehicles equipped with torque converters have limited shock absorption system capabilities. When the vehicle is coasting at a low speed and then the accelerator is pressed, the whole vehicle will shake, and the shaking phenomenon will be more obvious when the throttle is larger. The reason is that the torque converter has a torque-increasing effect before coupling, so the developers generally set it to open the coupling clutch in the low speed section. Before coupling, due to the working characteristics of the torque converter, the engine speed and the turbine speed are not synchronized at this time. If the engine speed is lower than the turbine speed, when the driver presses the accelerator, the engine speed rises under the action of the engine output torque, and the engine speed will quickly exceed the turbine speed. Similarly, this phenomenon will also occur in the non-coupling working area during the process of vehicle speed and torque decreasing after releasing the accelerator. The static characteristics of the torque converter are classified as torque reverse transmission conditions, and industry personnel are accustomed to calling this phenomenon speed crossing conditions. In the torque reverse transmission condition, the size of the transient impulse of the forward and reverse switching of the turbine output torque will cause the vehicle to shake, which is manifested as the greater the slope of the engine speed through the turbine speed, the greater the vehicle shaking will be. For example Figure 1 As shown in the figure, the general control means is mainly based on the simple linear table lookup to obtain the torque intervention value when the engine speed is greater than the turbine speed, requesting to reduce the engine torque so as to slow down the slope of the engine speed increase, thereby solving the problem of vehicle shaking during torque reverse transmission. Some current algorithms provide solutions with hysteresis in control during continuous dynamic driving, insufficient control means, insufficient power output, and poor driving perception.

[0025] Reference Figure 2 As shown, the torque control method may include the following steps:

[0026] S201: Acquire first vehicle information at a first moment in real time, wherein the first vehicle information includes a first engine speed, a first turbine speed, a first accelerator pedal opening, a first engine output torque, and a first engine water temperature.

[0027] In some embodiments, during the driving process of the vehicle, the first vehicle information at the first moment can be obtained in real time. Specifically, the first vehicle information can include the first engine speed, the first turbine speed, the first accelerator pedal opening, the first engine output torque and the first engine water temperature. In one embodiment, the first moment is a past moment, wherein the first moment can be a preset time interval with the current moment, and the preset time interval can be adaptively set based on the torque intervention value confirmation speed of the transmission controller. For example, when the transmission controller can confirm the torque intervention value within 50ms based on the torque control method provided in this application, the preset time interval can be set to 50ms, that is, the first moment is a past moment 50ms away from the current moment. In other embodiments, the preset time interval can also be set based on other methods, and this application does not impose any restrictions on this.

[0028] To facilitate understanding of this solution, the first moment is understood as the K-1 moment, that is, the engine speed Ne (unit rpm), turbine speed Nt (unit rpm), accelerator pedal opening Pos (unit %), and engine output torque (unit N·M) at the K-1 moment can be obtained in real time.

[0034] X(k) - =AX(k-1)+Bu(k-1)+w(k) Formula 1

[0035] Among them, X(k-1) represents the system state predicted at time k-1, where the system state includes the first engine speed, the first vehicle speed, and the first driving distance. A represents the transfer matrix of the calculation model, a simplified expression of modeling, here is the matrix relationship between the first vehicle speed, the first engine speed, and the first formal distance. B represents the control matrix of the calculation model, some normalized parameters simplified in the modeling process, such as moment of inertia*speed ratio, here is moment of inertia*speed ratio*first / (first mass*first wheel radius). u(k-1) represents the control input of the preset model, such as the force magnitude that changes with time, here is the first required torque calculated by the first accelerator pedal,, X(k) - It represents the first system state predicted at time k at time k-1, and w(k) represents the system process noise at time k.

[0036] When calculating the system state predicted at time k-1, the engine speed, vehicle speed and travel distance may be used as input parameters for calculation, so that the system state predicted at time k-1 can be obtained by calculation using formula 1.

[0037] Z(k)=HX(k)+v(k) Formula 2

[0038] Wherein, Z(k) represents the measurement value at time k, which may include the second engine speed, the driving speed and the second driving distance at the second time, X(k) represents the system state at time k, H represents the measurement system parameters, including the relationship matrix of the second engine speed, the driving speed and the second driving distance at the second time, and v(k) represents the measurement error at time k.

[0039] P(k) - =FP(k-1)F T +Q Formula 3

[0040] Among them, P(k) - represents the system process variance at time k-1, F represents the transfer matrix of the calculation model, a simplified expression of modeling, here is the matrix relationship between the first vehicle speed, the first engine speed, and the first form distance, F T represents the matrix transpose, and Q represents the process noise variance.

[0041] K g (k) = P(k) - H T (HP(k) -H T +R) -1 Formula 4

[0042] Among them, K g (k) represents the Kalman filter gain, P(k) - represents the system process variance at time k-1, H T represents matrix transpose, H represents measurement system parameters, including a relationship matrix of the second engine speed, the vehicle speed and the second driving distance at the second moment, and R represents measurement noise variance.

[0043] X(k)=X(k) - +K g (k)(Z(k)-X(k) - )Formula 5

[0044] Among them, X(k) represents the system state predicted at time k, X(k-1) represents the system state predicted at time k-1, and K g (k) represents the Kalman filter gain, Z(k) represents the measurement value at time k, and the measurement value may include the second engine speed, the driving speed and the second driving distance at the second time.

[0045] P(k)=(1-K g (k)H)P(k) - )Formula 6

[0046] Where P(k) represents the process variance of the K system, K g (k) represents the Kalman filter gain, H represents the measurement system parameters, including the relationship matrix of the second engine speed, the driving speed and the second driving distance at the second moment, P(k) - represents the system process variance at time k-1.

[0047] In some embodiments, after each round of engine predicted speed calculation is completed, the system process variance P(k) at the current moment can be calculated and used as the system process variance P(k) at the k-1 moment in the next round of engine predicted speed calculation process. - .
