The following describes a control method, a device, a vehicle, and a storage medium of a vehicle torque according to an embodiment of the present application with reference to the accompanying drawings. Aiming at the problems that the driving training mechanism mentioned in the background technology center is used for meeting the examination requirements of different students, so that the students need to be prepared for training, and then part of vehicles are idle, and resource waste is caused, the application provides a control method of vehicle torque. From this, solved and because of need satisfying the examination card demand of different students, lead to multiple different motorcycle types to appear that the vehicle is idle, cause the scheduling problem of wasting of resources, through installing automatic gearshift additional on manual fender vehicle, satisfy the daily training of examination card demand of different students, improved the suitable configuration of vehicle resource, and the cost is reduced.
Specifically, fig. 1 is a schematic flow chart of a method for controlling vehicle torque according to an embodiment of the present application.
In the embodiment of the application, the vehicle comprises a manual gear shifting mechanism and an automatic gear shifting mechanism, and the system components related to the control method of the vehicle torque mainly comprise: VCU (Vehicle Control Unit, vehicle controller), MT (Manual Transmission, manual gearbox), manual shift mechanism, automatic shift mechanism, MCU (Motor Control Unit, electric drive control system), BMS (Battery Management System, battery control system), ICM (Instrument Communications Interface, combination meter), manual-automatic mode switch, brake pedal, and clutch pedal.
As shown in fig. 1, the control method of the vehicle torque includes the steps of:
in step S101, a current driving mode of the vehicle is detected.
Further, in some embodiments, detecting a current driving mode of the vehicle includes: detecting whether a driving mode switching instruction is received; if a switching instruction is received, the manual gear shifting mechanism is set to be any forward gear, and when the opening of the brake pedal is larger than the preset opening, the manual gear shifting mechanism is controlled to be switched to the automatic gear shifting mechanism for working, so that the current driving mode is an automatic gear driving mode; and if the switching instruction is not received, maintaining the current driving mode as a manual driving stopping mode.
Specifically, as shown in fig. 2, the driving modes of the vehicle specifically include a manual-gear driving mode and an automatic-gear driving mode. In the manual driving mode, the instrument panel does not display gear information and also does not receive gear information of automatic gear shifting; in the automatic gear driving mode, the instrument panel displays gear information, the whole vehicle is in a flameout state, and after a driver needs to step on a brake to restart, the whole vehicle controller acquires and responds to the gear information of the automatic gear shifting mechanism. After the vehicle is started, the current driving mode of the vehicle can be detected through information such as an instrument panel, and in general, the driving mode of the vehicle after the starting is defaulted to be a manual driving mode.
Further, after the vehicle is started, judging whether a driver carries out a mode switching instruction through a manual mode switching switch, if the switching instruction is received, setting the manual gear shifting mechanism as any forward gear, and when the opening of the brake pedal is larger than a preset opening, controlling the vehicle to switch to an automatic gear shifting mechanism to work by the manual gear shifting mechanism, so that the current driving mode is an automatic driving mode, wherein the preset opening of the brake pedal can be a threshold preset by a user, can be a threshold obtained through limited experiments, can be a threshold obtained through limited computer simulation, and is not particularly limited. Preferably, the preset opening degree in the embodiment of the present application may control an opening degree at which the vehicle remains parked; and if the switching instruction is not received, maintaining the current driving mode as a manual driving stopping mode.
For example, if the current driving mode of the vehicle is a manual mode, if the vehicle controller receives a command for switching the driving mode, the manual gear shifting mechanism may be set to 2 gear, and when the opening of the brake pedal is the opening for controlling the vehicle to keep parking, the manual gear shifting mechanism is controlled to switch the vehicle to operate, so that the current driving mode is an automatic driving mode, and if the vehicle controller does not receive the command for switching the driving mode, the current driving mode is maintained to be the manual driving mode.
In step S102, when the current driving mode is detected to be the automatic shift driving mode, first gear information of the automatic shift mechanism is acquired, and second gear information of the manual shift mechanism is acquired.
The first gear information and the second gear information may be in a state where the gears are located, such as forward gear, reverse gear, neutral gear, and the like.
Specifically, when the current driving mode of the vehicle is detected to be the automatic gear driving mode, the embodiment of the application can acquire the first gear information of the automatic gear shifting mechanism and the second gear information of the manual gear shifting mechanism respectively, so that the states of the automatic gear shifting mechanism and the manual gear shifting mechanism are determined.
In step S103, the target vehicle torque corresponding to the first gear information and the second gear information is matched, and the driving motor output of the vehicle is controlled in accordance with the target vehicle torque.
Further, in some embodiments, when the second gear information is the first forward gear or the neutral gear, matching the target vehicle torque corresponding to the first gear information and the second gear information, and controlling the driving motor output of the vehicle according to the target vehicle torque, including: if the first gear information is the second forward gear, taking the first torque as a target vehicle torque, and controlling the output of a driving motor of the vehicle according to the first torque, wherein the first torque is smaller than or equal to the minimum value of the maximum allowable driving torque of the driving motor, the user request torque and the overspeed protection torque; and if the first gear information is the first reverse gear, taking the second torque as a target vehicle torque, and controlling the output of a driving motor of the vehicle according to the second torque, wherein the absolute value of the second torque is smaller than or equal to the minimum value of the maximum reverse driving torque absolute value, the user request torque absolute value and the overspeed protection torque absolute value of the driving motor.
The first forward gear is a forward gear in a manual gear driving mode, the second forward gear is a forward gear in an automatic gear driving mode, and the first reverse gear is a reverse gear in the automatic gear driving mode; the first torque is the torque actually output by the motor when the manual gear is in the forward gear or the neutral gear and the automatic gear is in the forward gear; the second torque is the torque actually output by the motor when the manual gear is in the forward gear or the neutral gear and the automatic gear is in the reverse gear. In the running process of the vehicle, the whole vehicle controller can perform mode management and torque limitation on the whole vehicle output torque according to the driving mode of the vehicle, the first gear information of the automatic gear shifting mechanism and the second gear information of the manual gear shifting mechanism. The method comprises the steps that under a manual driving mode, a torque management mode is divided into a zero torque mode, a driving mode and an energy recovery mode, and at the moment, a whole vehicle controller enters different torque modes according to driving conditions; in the automatic drive mode, since the vehicle reverse is achieved by the motor reverse, torque mode management can be classified into a zero torque mode, a drive mode, a reverse mode, and an energy recovery mode.
Specifically, when the second gear information of the vehicle is a forward gear or a neutral gear, if the first gear information is also the forward gear, the whole vehicle controller controls the vehicle to enter a driving mode, in the driving mode, the actual output torque of the motor is a forward torque, the torque is taken as a target vehicle torque, and the driving motor output of the vehicle is controlled according to the torque, wherein the forward torque actually output by the motor is smaller than or equal to the minimum value of the maximum allowable driving torque of the driving motor, the user request torque and the overspeed protection torque; and when the automatic gear is a reverse gear, the whole vehicle controller controls the vehicle to enter a reverse gear mode, in the reverse gear mode, the actual output torque of the motor is negative torque, the torque is taken as the target vehicle torque, and the output of the driving motor of the vehicle is controlled according to the torque, wherein the absolute value of the negative torque actually output by the motor is smaller than or equal to the minimum value of the maximum reverse driving torque absolute value, the user request torque absolute value and the overspeed protection torque absolute value of the driving motor.
Further, in some embodiments, when the second gear information is the second reverse gear, matching the target vehicle torque corresponding to the first gear information and the second gear information, and controlling the driving motor output of the vehicle according to the target vehicle torque, including: if the first gear information is the second forward gear, reversing the output torque of the driving motor to be third torque, and controlling the vehicle to drive forwards according to the third torque; and if the first gear information is the first reverse gear, reversing the output torque of the driving motor to fourth torque, and controlling the vehicle to drive backwards according to the fourth torque.
The second reverse gear is a reverse gear in a manual gear driving mode; the third torque is torque actually output by the motor when the manual gear is a reverse gear and the automatic gear is a forward gear; and the fourth torque is the torque actually output by the motor when the manual gear and the automatic gear are simultaneously the reverse gear.
Specifically, when the manual gear of the vehicle is a reverse gear, the speed change box arranged in the vehicle can change the functions of rotating speed, torque and the like from the engine, and when the manual gear is the reverse gear and the automatic gear is the forward gear, the whole vehicle controller controls the vehicle to enter a reverse gear mode, and meanwhile, the torque actually output by the motor needs to be reversed, namely negative torque is output, so that the whole vehicle controller controls the vehicle to advance; when the manual gear is a reverse gear and the automatic gear is also a reverse gear, the whole vehicle controller controls the vehicle to enter a driving mode, and meanwhile, the torque actually output by the motor needs to be reversed, namely, the forward torque is output, so that the whole vehicle controller controls the vehicle to reverse.
To sum up, as shown in fig. 3, fig. 3 is a flow chart of manual R-gear automatic shift driving torque control according to an embodiment of the present application, including the following steps:

Further, in some embodiments, the method for controlling vehicle torque further includes: when the current driving mode is detected to be a manual gear driving mode, second gear information of the manual gear shifting mechanism is acquired; and matching the target vehicle torque corresponding to the second gear information, and controlling the output of a driving motor of the vehicle according to the target vehicle torque.
Specifically, if the current vehicle is in the manual driving mode, if the acquired second gear information of the manual gear shifting mechanism is the first forward gear, the vehicle control unit is enabled to control the vehicle to advance, and if the acquired second gear information of the manual gear shifting mechanism is the second backward gear, the vehicle control unit is enabled to control the vehicle to retreat.
When the current vehicle is in the manual transmission driving mode, the control mode is identical to the control mode of the existing manual transmission vehicle, and detailed description is omitted for avoiding redundancy.
Further, in some embodiments, the method for controlling vehicle torque further includes: calculating the current speed ratio of the vehicle in the running process of the vehicle; calculating the actual gear of the vehicle according to the current speed ratio; and overspeed protection is carried out on the vehicle according to the actual gear.
Specifically, as shown in fig. 4, during the running of the vehicle, if the current vehicle is in the manual gear driving mode, the driver performs gear engagement and clutch stepping through the manual gear shifting mechanism to realize starting, and during the starting, if the clutch is released too quickly or the operation is improper, the vehicle can shake, stop, stall and other conditions; in the running process, the whole vehicle controller collects and calculates the speed ratio calculation of the current vehicle through a hard wire, so as to judge the actual manual gear in the MT gearbox, and overspeed protection is carried out on the speed of the vehicle according to the actual manual gear; if the current vehicle is in the automatic gear driving mode, the whole vehicle controller judges the actual gear in the MT gearbox and shields the clutch pedal by calculating the current speed ratio of the vehicle, and the gear information in the automatic gear driving mode is switched to the forward gear by stepping on the brake, so that the vehicle can start normally, and the situations of shaking, flameout and the like in the starting and driving processes of the vehicle in the automatic gear driving mode are ensured.
According to the vehicle torque control method, when the current driving mode of the vehicle is the automatic gear driving mode, the first gear information of the automatic gear shifting mechanism is collected, the second gear information of the manual gear shifting mechanism is collected, and the corresponding target vehicle torque is matched, so that the driving motor output of the vehicle is controlled.
