Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0044] With the development of society, cars have entered thousands of households and become an indispensable part of people's daily life. As people's needs change, cars, in addition to meeting their initial basic functions as a means of transportation, also need to meet people's comfort needs in order to enhance the user's driving experience.

[0045] For example, when starting a vehicle, maintaining high torque at a low speed can provide the driver with starting confidence, especially when starting on a slope, the high torque at a low speed can provide the driver with starting confidence while allowing the vehicle to start smoothly.

[0046] In the prior art, in order to ensure the linear requirement of torque output during vehicle driving, most vehicles set a lower torque at low engine speed and small accelerator pedal opening. However, when the vehicle starts, the starting power provided by the low torque is weak, affecting the driving experience.

[0047] The following will explain in detail how to meet the low-speed high-torque output while ensuring the linear requirements of a standard vehicle during driving, thereby improving the driving experience, in conjunction with specific embodiments and drawings.

[0048] Embodiment 1

[0049] See also Figure 1 , which shows an engine torque output control method in a first embodiment of the present invention, and the method includes steps S10 to S13.

[0050] Step S10, when the vehicle starts to travel, the vehicle speed, engine speed and accelerator pedal opening are obtained in real time.

[0051] Among them, in this embodiment, the vehicle starting and driving process represents the time period from the vehicle starting to the vehicle speed stabilizing to a preset speed range, for example, the vehicle speed stabilizes to 10km / h, and the vehicle speed, engine speed and accelerator pedal opening can represent the time nodes of the vehicle in the starting and driving process to a certain extent.

[0052] Step S11 : determining a first torque and a second torque for the engine output respectively according to the engine speed and the accelerator pedal opening.

[0053] Among them, in this embodiment, two torque values, the first torque and the second torque, can be determined by the engine speed and the accelerator pedal opening, wherein one torque value is to ensure the linear output of the engine torque of the vehicle during driving, that is, the same as the existing torque setting, matching the low torque at low engine speed and small accelerator pedal opening, and the other torque value is a torque value obtained by another set of torque setting rules different from those in the prior art, for example, providing a higher torque output at low engine speed and small accelerator pedal opening. Specifically, the purpose of applying the newly set torque value is achieved by adding data in the internal application layer of the vehicle controller.

[0054] Specifically, the torque value of one of the first torque and the second torque is greater than the torque value of the other, and the first torque is within a first preset range and the second torque is within a second preset range. The first preset range and the second preset range can be set according to actual conditions.

[0055] In addition, in some optional embodiments of the present invention, the step of determining the first torque and the second torque for the engine output according to the engine speed and the accelerator pedal opening may specifically include:

[0056] Searching a first torque corresponding to the engine speed and the accelerator pedal opening in a first preset mapping table;

[0057] The second torque corresponding to the engine speed and the accelerator pedal opening is searched in a second preset mapping table.

[0058] Specifically, the first torque and the second torque are both stored in the form of a mapping table in the internal application layer of the vehicle controller, so as to obtain the corresponding torque value when the engine speed and the accelerator pedal opening are obtained.

[0059] Furthermore, the settings of the first mapping table and the second mapping table can be set as shown in Table 1 and Table 2 respectively.

[0060] Table 1

[0061]

[0062] Table 2

[0063]

[0064] It can be clearly seen from Tables 1 and 2 above that under the conditions of low engine speed and accelerator pedal, the torque in Table 2 is higher and the power is better when starting.

[0065] Step S12: determining corresponding weights of the first torque and the second torque according to the vehicle speed.

[0066] Among them, the vehicle speed is used to determine whether the vehicle is currently in a low-speed or high-speed state. When the vehicle is in a low-speed state, high torque is output as much as possible to ensure that the vehicle can also ensure good power output at a low speed. Specifically, the relationship between the vehicle speed and the weight size can also be obtained in the form of a mapping table. In specific implementation, the mapping table can be set as shown in Table 3 below.

[0067] Table 3

[0068] Speed 0 2 4 6 8 10 First torque weight 0 0.2 0.4 0.6 0.8 1 Second torque weighting 1 0.8 0.6 0.4 0.2 0

[0069] It should be noted that in this embodiment, the first torque is smaller than the second torque. At low speed, the weight of the second torque is greater than the weight of the first torque. Below a certain speed, the weight of the second torque increases as the speed decreases. Above a certain speed, the weight of the second torque slowly decreases as the speed increases until the first torque is completely used for output at speeds above 10 km / h. While achieving low-speed high-torque output, the torque performance of normal driving is not affected.

[0070] Step S13: Assigning and summing the first torque and the second torque by using the weight to control the engine to output torque.

[0071] Specifically, the first torque and the second torque are assigned weights corresponding to the first torque and the second torque respectively to obtain weighted first torque and second torque, and then the weighted first torque and second torque are added and summed to obtain the torque actually to be output by the engine.

[0072] In summary, the engine torque output control method in the above embodiment of the present invention sets two sets of torque output standards. When the vehicle starts to drive, the weights of the two sets of torque outputs are determined according to the vehicle speed, and the weighted torque is used as the torque output of the engine. While meeting the low-speed high-torque output, it also ensures the linear requirements of the standard vehicle when driving, thereby improving the driving experience. This solves the problem in the prior art that the starting power is weak and affects the driving experience when the vehicle starts to drive.

[0073] Embodiment 2

[0074] See also Figure 2 , shown is an engine torque output control method in a second embodiment of the present invention, the method includes steps S20 to S25.

[0075] Step S20, when the vehicle starts to travel, the vehicle speed, engine speed and accelerator pedal opening are obtained in real time.

[0076] Step S21, determining a first torque and a second torque for engine output respectively according to the engine speed and the accelerator pedal opening.

[0077] Step S22: determining corresponding weights of the first torque and the second torque according to the vehicle speed.

[0078] Step S23: assigning and summing the first torque and the second torque by using the weight to control the engine to output torque.

[0079] Step S24, obtaining the gearbox gear position of the vehicle, and determining a correction coefficient according to the gearbox gear position and the engine speed.

[0080] Among them, in order to further improve the driver's driving experience at low speed, that is, to ensure low speed and high torque to ensure the power of the vehicle, in the specific implementation, the gear position of the gearbox is obtained, and the correction system is determined according to the gear position of the gearbox and the engine speed. Specifically, the role of the correction coefficient is mainly to amplify the torque required by the driver, that is, when it is determined that the vehicle is currently in a low speed and low gear state, the output torque is increased to ensure the power of the vehicle.

[0081] Step S25, correcting the torque after the assignment and summation according to the correction coefficient to control the engine to output torque.

[0082] Specifically, the correction coefficient may be output in the form of a mapping table. In a specific implementation, the mapping table of the correction coefficient may be set as shown in Table 4 below.

[0083] Table 4

[0084]

[0085] In addition, since the correction is only performed in a low gear, the correction coefficient is set to a default value of 1 in a high gear. In order to avoid repeated acquisition of the correction coefficient in a high gear, in some optional embodiments of the present invention, the step of acquiring the gearbox gear of the vehicle and determining the correction coefficient according to the gearbox gear and the engine speed also includes:

[0086] Determining whether the gear position of the transmission is lower than a preset gear position;

[0087] If so, a step is performed to correct the torque after the assignment summation according to the correction coefficient to control the engine to output torque.

[0088] Among them, the preset gear can be set according to actual conditions. In this embodiment, the preset gear is 4 gears, which is not limited here.

[0089] In summary, the engine torque output control method in the above embodiment of the present invention sets two sets of torque output standards. When the vehicle starts to drive, the weights of the two sets of torque outputs are determined according to the vehicle speed, and the torque after weighted addition is used as the torque output of the engine. While meeting the low-speed high-torque output, it also ensures the linear requirements of the standard vehicle when driving, improves the driving experience, and amplifies and corrects the torque before the torque output, which solves the problem in the prior art that the starting power is weak and affects the driving experience when the vehicle starts to drive, and further improves the vehicle's power at low speed and low gear.

[0090] Embodiment 3

[0091] See also Figure 3 , which shows the engine torque output control method proposed in the third embodiment of the present invention, and the method includes steps S30 to S35.

[0092] Step S30, when the vehicle starts to travel, the vehicle speed, engine speed and accelerator pedal opening are obtained in real time.

[0093] Step S31, determining a first torque and a second torque for the engine output respectively according to the engine speed and the accelerator pedal opening.

[0094] Step S32, determining whether the time during which the vehicle speed is lower than the preset vehicle speed meets a preset time range; if so, executing step S33.

[0095] Among them, the preset vehicle speed is the critical speed of the vehicle in a low-speed environment, such as 10km / h, 15km / h, which can be limited according to actual conditions. In practice, whether the output torque needs to be weighted and then re-output is mainly determined by whether the vehicle is in a low-speed environment. However, in the process of vehicle driving, due to certain special circumstances, the vehicle speed may suddenly drop below the preset speed and then instantly recover to above the preset speed. Among them, certain special circumstances include but are not limited to acceleration after sudden braking. According to normal procedures, the vehicle needs to re-weight the torque. In fact, the current vehicle is not in a normal low-speed operating environment. In order to avoid frequent switching of weighting of the vehicle, when the vehicle is at a low speed for a preset time range, the torque is weighted to improve the safety of the vehicle.

[0096] Step S33: determining corresponding weights of the first torque and the second torque according to the vehicle speed.

[0097] Step S34: Assigning and summing the first torque and the second torque by using the weight to control the engine to output torque.

[0098] In summary, the engine torque output control method of the above embodiment of the present invention sets two sets of torque output standards. When the vehicle starts to drive, the weights of the two sets of torque outputs are determined according to the vehicle speed, and the torque after weighted addition is used as the torque output of the engine. While meeting the low-speed high-torque output, it also ensures the linear requirements of the standard vehicle when driving, improves the driving experience, and increases the judgment conditions for torque weighting. It solves the problem in the prior art that the starting power is weak and affects the driving experience when the vehicle starts to drive, while improving the safety of vehicle driving.
