Abstract

The invention provides a ludicrous accelerating mode control method, a storage medium and an electric automobile. The ludicrous accelerating mode control method comprises the steps of step 301, detecting stepping operation of a brake pedal after entering an activated state; and if detecting the stepping operation of the brake pedal, executing a step 302; and otherwise, executing a step 306; step 302, detecting whether a current vehicle speed is lower than a preset static vehicle speed or not; and if the current vehicle speed is lower than the preset static vehicle speed, executing a step 303;step 303, adjusting a motor torque of the electric automobile to an initial pre-torque, and starting initial activation timing; step 304, if detecting releasing operation of the brake pedal when the initial activation timing does not reach an initial activation preset time length, executing a step 306; and otherwise, executing a step 305; step 305, when the initial activation timing reaches the initial activation preset time length, ending a ludicrous accelerating mode and returning to a preparing state to detect; and step 306, increasing a motor rotation speed according to a pre-calibrated curve. The invention provides a ludicrous accelerating mode which can be safely used during starting.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a control method, a storage medium and an electric vehicle in a violent acceleration mode. Background technique [0002] In the prior art, there is a mode in which the electric vehicle can be accelerated by short-term high-torque boosting of the electric motor. This acceleration mode can meet the torque requirement demanded by the driver under rapid acceleration conditions, and at the same time improve the transient emission of the engine. In actual use, the acceleration mode that uses the short-term high-torque boost of the motor is also called the violent acceleration mode of electric vehicles. [0003] The violent acceleration mode of electric vehicles is a working mode to realize the driver's speed experience. It can allow the output torque of the front and rear motors to be above the peak torque. Because it involves personal safety, its control strategy is very strict. [0004] ...
