Vehicle accelerator control method, device and vehicle

Abstract

The invention discloses an automobile accelerator control method, an automobile accelerator control device and an automobile. The method comprises the steps of acquiring running state of the automobile; if the running state of the automobile is a starting state, judging whether the first time of operation of a driver is accelerator pedal trampling or not; if the first time of operation of a driver is accelerator pedal trampling, controlling engine torque output so as to limit the speed of the automobile to be lower than a preset speed value until the opening degree of the accelerator pedal is reset to be zero; if the operation state of the automobile is a running state, acquiring a maximum variation amplitude of the opening degree of the accelerator pedal within a previous calculation period; acquiring a variation rate threshold of the opening degree of the accelerator pedal within a present calculation period according to the maximum variation amplitude within the previous calculation period; controlling the ultimate actual executive opening degree of the accelerator according to the variation rate threshold of the opening degree of the accelerator pedal. By utilizing the method disclosed by the embodiment of the invention, the accuracy in identifying maloperation of the accelerator pedal is improved, parameters for the accelerator control method can be flexibly configured, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle electronic control, in particular to a vehicle accelerator control method, device and vehicle. Background technique [0002] As the number of vehicles is increasing day by day, the traffic accidents caused by driver's operation errors are also increasing. In order to reduce the occurrence of this type of accident, it can be realized by installing the accelerator pedal error prevention device on the vehicle. [0003] In the current accelerator pedal anti-error device, one method is to use a mechanical hydraulic device to allow the accelerator operation to achieve an operation effect similar to that of a seat belt, that is, the accelerator can be moved only when the accelerator is stepped on slowly, and if the accelerator is stepped on too hard, the accelerator is stuck and does not move. However, this method requires additional devices to be installed on the vehicle, which increases the cost. [...

AI Technical Summary

Problems solved by technology

However, this accelerator pedal anti-error device all judges whether the operation of the current accelerator pedal is from the driver's normal will by setting a fixed accelerator pedal opening as the threshold, and there are the following problems: (1) The setting of the threshold needs to pass A large number of real vehicle experiments are used for statistical induction, which needs to cover various possible situations, has little flexibility, and is difficult to cover various driving conditions and normal recognition of different driving styles; (2) the driver's driving There are many restrictions on habits, which greatly reduces the driving pleasure and the user experience is poor
