Problems solved by technology

[0004] However, in the above-mentioned driving mode switching process, the difference between different driving modes is only that the gears of the vehicle are different, so that in each driving mode, the change of the vehicle dynamic performance is very small, and finally the user is in this driving mode. very little experience

Embodiment Construction

[0037] Currently, vehicles have different driving modes. Take the vehicle with two driving modes of D gear and S gear as an example, when the driving mode of the vehicle is switched from D gear to S gear, only the gear of the vehicle is changed, and the impact on the vehicle caused by the different gears The change in power performance is very small, which ultimately leads to the user's little experience in the D or S driving mode.

[0038] In view of the above problems, the embodiment of the present invention provides an accelerator pedal, the base of the accelerator pedal is provided with a control assembly, the control assembly can change the torque and stroke of the accelerator pedal, and then can change the speed of the vehicle at a certain level. The power performance in the driving mode improves the user experience of the user in the driving mode.

[0039] Such as figure 1 As shown, the embodiment of the present invention provides an accelerator pedal, and the acceler...

Abstract

The invention relates to an accelerator pedal and a vehicle control method and system. The accelerator pedal comprises a pedal, a base and a pedal link, wherein the base is suitable for fixing the accelerator pedal on a vehicle chassis; a first end of the pedal link is connected with the pedal, a second end of the pedal link is connected with the base, and the first end and the second end are arranged oppositely; a control assembly which is suitable for changing the force moment and stroke of the accelerator pedal is arranged inside the base. According to the accelerator pedal, torque output from an engine and accelerator pedal openness required during the gear shifting of a transmission can be effectively changed, and then, the power performance of a vehicle is effectively changed, so that user experience in different driving modes can be improved.

Description

technical field [0001] The invention relates to the field of vehicle control, in particular to an accelerator pedal, a vehicle control method and a system. Background technique [0002] At present, automatic transmission cars all have different driving modes, and the driver can choose different driving modes to meet the driving needs. For example, an ordinary automatic car can have two driving modes of D gear and S gear, while a high-end automatic car can have driving modes such as Sport+ gear and Comfort gear in addition to the two driving modes of D gear and S gear. [0003] When changing the driving mode of the vehicle according to the driver's driving mode switching operation, the signal generated by the driving mode switching operation is usually sent to the gearbox controller first, and the gearbox controller generates a corresponding driving mode switching request according to the signal and sends it to To the engine controller, after receiving the switching request,...
