Problems solved by technology

[0003] In order to reach the destination quickly, many drivers usually start in second gear directly. In this case, the speed of the vehicle usually does not match the gear position, which is likely to cause serious wear and tear on the clutch of the vehicle, and ultimately increase the maintenance cost of the vehicle.

[0039] An embodiment of the present invention provides an engine control method for controlling the state of the gear locker 110 to avoid clutch wear caused by the mismatch between the speed of the vehicle and the gear. see figure 2 , is a flow chart of the engine control method provided by the embodiment of the present invention. The engine control method includes:

[0040] Step S201: Obtain the transmission output shaft speed, transmission gear position information and accelerator opening.

[0041] It should be noted that the transmission output shaft speed, transmission gear position information and accelerator opening are collected and transmitted through the data acquisition module 114. By analyzing the transmission output shaft speed and transmission gear position information, the running state of the vehicle and the transmission 130 position information can be determined. gear status.

[0042] Step S202: Adjust the state of the gear locker 110 based on the transmiss...

[0085] see Figure 7 , Figure 7 An engine control method provided by a preferred embodiment of the present invention. It should be noted that the basic principles and technical effects of the engine control method provided by this embodiment are the same as those of the above-mentioned embodiments. Corresponding content. The engine control method includes:

[0086] Step S201: Receive timing information transmitted by a timer.

[0087] Step S202: Determine whether the timing information is greater than or equal to a preset third threshold, if yes, execute step S203; if no, execute step S201.

[0088] Step S203: Obtain the transmission output shaft speed, transmission gear information and accelerator opening.

[0089] Step S204: Adjust the state of the gear locker 110 based on the transmission output shaft speed and transmission gear information.

[0090] Step S205: Detect whether the vehicle is faulty, if yes, execute step S206; if not, execute step S208.

Abstract

Embodiments of the present invention provide an engine control method and device, which relate to the technical field of automobiles. The method and device adjust the state of the gear locker based on the speed of the transmission output shaft and the gear position information of the transmission, and then adjust the state of the engine based on the state of the gear locker and the opening of the accelerator, so that when the gear locker is in the locked When the engine is in the stopped state and the accelerator opening is greater than the preset second threshold, the engine will be controlled to limit the speed and torque, so that when the driver drives the vehicle, he can only start in the first gear or reverse gear, avoiding the accident caused by the vehicle starting in a high gear. Reduced clutch wear, prolonging the service life of the vehicle.

Description

technical field [0001] The present invention relates to the technical field of automobiles, in particular to an engine control method and device. Background technique [0002] With the continuous development of the times and the continuous advancement of technology, the number of cars in various places is gradually increasing. Automobiles are an important means of transportation for people to travel in modern society. Private cars, city buses or buses are highly used. [0003] In order to reach the destination quickly, many drivers usually start directly in the second gear. In this case, the speed of the vehicle usually does not match the gear position, which is likely to cause serious wear and tear on the clutch of the vehicle, and ultimately increase the maintenance cost of the vehicle. . Contents of the invention [0004] The purpose of the present invention is to provide an engine control method and device to solve the above problems. [0005] In order to achieve th...
