Abstract

The invention relates to the field of automobiles, in particular to an automobile acceleration control method and a vehicle. The automobile acceleration control method comprises the following steps: acceleration activation: determining the gear of the vehicle and the opening degree of an accelerator pedal in the process of judging that the vehicle is converted from a reverse towing state to a forward towing state, and controlling the transmission torque of a transmission to change at a preset rising rate within a preset time according to the gear of the vehicle and the opening degree of the accelerator pedal; wherein the preset time starting point is that the torque of the engine is equal to the transmission torque of the transmission. According to the automobile acceleration control method, in the process that the sliding of the vehicle is changed into re-acceleration, the transmission torque of the transmission is changed at the preset rising speed within the preset time, the rushing of the whole vehicle can be effectively avoided, and the noise of a transmission system is eliminated.

Description

technical field [0001] The present disclosure generally relates to the field of automobiles, and in particular to an automobile acceleration control method and a vehicle. Background technique [0002] With the popularity of vehicles, people have higher and higher requirements for vehicle driving comfort. Existing automatic transmission vehicles are prone to vibration and noise problems during the process of coasting and re-accelerating in each gear. [0003] When the vehicle is in the process of coasting, the whole vehicle drags the engine in reverse, that is, the engine is in a state of no fuel injection. At this time, the engine torque value is a negative value, and the absolute value is approximately equal to the transmission torque of the transmission. When the accelerator pedal is pressed, the engine torque value starts to rise from a negative value, and the transmission torque value begins to decrease from a positive value. After the engine torque is equal to the tra...
