Embodiment Construction
[0042] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, specific embodiments will be described in detail below with reference to the accompanying drawings.
[0043] like figure 1 As shown, the shift lever 100 drives the shift fork 202 and the collar 201 to move left and right, so that the collar 201 is engaged with a driven gear 602; thus, the power provided by the engine passes through the power input shaft 300, the driving gear 601, and the driven gear in turn. The gear 602 transmits power to the power output shaft 400, and the power output shaft 400 transmits power to the differential (not shown in the figure). The driving gear 601 is fixedly connected with the intermediate shaft 500 , and the drive wheel 700 is fixedly connected with the power input shaft 300 .

The invention belongs to the technical field of pause prevention during gear combination, and particularly relates to a method and a device for lightening pause during shifting up. The method comprises the following steps that (1) a controller detects the current gear m and the running speed v when an automobile runs; (2) the controller calculates the required rotating speed n of an engine when the automobile is kept at the running speed v and at the gear m+1; (3) the controller receives separation signals of the engine and a speed changer; (4) the controller controls the rotating speed of the engine at the rotating speed n, and enables the engine to be kept at the rotating speed n for t seconds; (5) a driver engages the gear m+1 or the gear m-1 in t seconds. According to the method and the device for lightening the pause during shifting up, after the driver steps on the clutch, the rotating speed of the engine is controlled at the required rotating speed n of the engine when the automobile put into the gear m+1 is kept at the running speed v. As the rotating speed of the engine is also the rotating speed n at the moment, the rotating speed difference between the rotating speed of the engine and the rotating speed of an intermediate shaft, and the problem of the pause during shifting up is resolved.
Description
technical field [0001] The invention belongs to the technical field of preventing overhanging when gears are combined, and in particular relates to a method and device for alleviating overhanging when upshifting. Background technique [0002] The general steps for shifting gears in a manual transmission car are as follows: [0003] Step 1: step on the clutch and release the accelerator, and the car enters the idling state at this time; [0004] Step 2: Engage in the desired gear; [0005] Step 3: Lift the clutch and refuel. [0006] Manual transmission models generally have different degrees of shifting and shaking when upshifting. This kind of shaking is caused by the speed difference between the engine and the intermediate shaft before and after the clutch is engaged during the upshift. [0007] This towering car affects the driving comfort of the whole vehicle and reduces the running quality of the whole vehicle. Contents of the invention [0008] The purpose of the...
