[0088] Further, refer to image 3 An electric vehicle acceleration and braking control method of the present invention is based on the first embodiment, step S30 also includes:

[0089] Step S300, judging whether the driving speed of the electric vehicle is greater than or equal to the preset second judging speed in the preset high-speed section speed;

[0090] After the collected acceleration signal and braking signal are valid at the same time and the current vehicle speed is greater than the preset first judgment speed, it is further judged whether the driving speed of the electric vehicle is greater than or equal to the preset high-speed interval speed (such as 70km / h to 120km / h) The preset second judgment speed in (eg 90km / h).

[0091] Step S301, if the driving speed of the electric vehicle is greater than or equal to the preset second judging speed, after maintaining the current driving speed for a preset third time, then at the minimum speed of the preset high-speed se...

Abstract

The invention discloses an electric vehicle acceleration and brake control method, control equipment and a storage medium, and the method comprises the steps: collecting an acceleration signal and a brake signal of an electric vehicle, and judging whether the acceleration signal and the brake signal are effective at the same time or not; when the acceleration signal and the brake signal of the electric automobile are valid at the same time, the current running speed of the electric automobile is obtained, and whether the current running speed is larger than or equal to a preset first judgment speed or not is judged; if the current driving speed is larger than or equal to the preset first judgment speed, the acceleration signal is responded, and the electric vehicle is accelerated; and if the current running speed is smaller than the preset first judgment speed, the braking signal is responded, and the electric automobile is braked. Therefore, misjudgment caused when the accelerator pedal and the brake pedal are stepped down at the same time is avoided, and the safety of passengers is better guaranteed.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to an electric vehicle acceleration and braking control method, control equipment and a readable storage medium. Background technique [0002] With the tense global energy situation and the increasing awareness of environmental protection, the number of electric vehicles is also increasing. When the vehicle is driving, it is possible that the accelerator pedal is pressed on the brake pedal by mistake, or the brake pedal and its related line speed are abnormal, so that the signals of the accelerator pedal and the brake pedal are valid at the same time (both stepped on) . At present, in pure electric vehicles, the situation that the vehicle controller responds to two signals at the same time is not allowed to exist, so there are two main ways to deal with it: 1. The vehicle controller responds to the accelerator pedal signal first; 2. The vehicle controller The controller gives prio...
