Problems solved by technology

[0003] However, using the figure 1 In the scheme shown, the peak torque of the motor is easy to trigger frequently, and the time for the motor to work at the peak torque is generally a few seconds. Continuous frequent triggering makes the motor and controller work in a high temperature environment for a long time, and the workload is heavy, which affects the core. The life of the device, and when a larger torque is really required, the controller will limit the output torque due to frequent triggering, resulting in insufficient power. At the same time, discharging with a peak current will also have a certain impact on battery life; figure 2 In the scheme shown, since the peak torque is limited to a certain value, the trigger probability is 0 when the vehicle is driving normally, and it cannot meet the driver's demand when the driver has an acceleration demand.

Embodiment Construction

[0025] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary, and embodiments of the present invention are described in detail below.

[0026] In the embodiment, the common control of the peak torque of the motor may have unnecessary frequent triggers, or 0 triggers when necessary. Such control of the peak torque of the motor seriously affects the driving experience of the driver during the actual driving of the vehicle. Therefore, , the embodiment of the present invention proposes a method for controlling rapid acceleration of the vehicle, which can prevent the frequent triggering of the peak power of the motor, and when the driver has a torque demand, by detecting the state of the vehicle, when the state of the vehicle meets the trigger condition, control The motor outputs standard peak torque to meet the driver's power requirements and improve user experience.

Abstract

The invention provides a method for controlling rapid acceleration of a vehicle, a computer storage medium and the vehicle. The method for controlling rapid acceleration of the vehicle comprises steps of the depth of an accelerator pedal being obtained; determining that the depth of the accelerator pedal exceeds a preset depth of the accelerator pedal, and detecting an effective trigger signal of the rapid acceleration trigger unit; and controlling the peak torque of the motor to be the standard peak torque. According to the method for controlling rapid acceleration of the vehicle, driving safety is improved while the power requirement is met, the service life of a motor, an electric controller and a battery is prolonged to a certain degree, a user can trigger the rapid acceleration function through a switch, and the user experience is improved.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a method for controlling sudden acceleration of a vehicle, a storage medium and a vehicle. Background technique [0002] At present, there are two main solutions to the peak torque processing of vehicle motors, such as figure 1 As shown, the peak torque is not triggered and limited, and the external characteristic torque T of the motor is to be achieved. max , the driver can step on the accelerator directly. Such as figure 2 As shown, when accelerating from 100 kilometers to start, it is triggered when the accelerator is stepped on rapidly. In order to achieve a better acceleration experience from 100 kilometers to 100 kilometers, the driver quickly steps on the accelerator to trigger the motor peak torque T max , and limit the peak motor torque to T lim . [0003] However, using the figure 1 In the scheme shown, the peak torque of the motor is easy to trigger frequently, and the t...
