[0060] See figure 1 , figure 1 It is a schematic flow chart of the control method of the electric vehicle provided in this embodiment, such as figure 1 As shown, the method includes the following steps:

[0061] Step 101 , when the current output torque of the electric vehicle is negative torque, receive a first braking operation on the brake pedal by the driver.

[0062] In this embodiment, when the electric vehicle is running and its current output torque is negative torque, if the driver needs to control the electric vehicle to decelerate, the driver can input the first braking operation to the brake pedal of the electric vehicle, namely When the brake pedal is depressed, the electric vehicle may receive a first braking operation input by the driver.

[0063]Wherein, the current output torque of the electric vehicle is a negative torque, it can be understood that the output torque of the drive motor of the electric vehicle is a negative torque, and in the above-mentioned...

[0100] See figure 2 , is a schematic structural diagram of an electric vehicle provided in this embodiment, as figure 2 As shown, the electric vehicle 200 includes:

[0101] The first receiving module 201 is configured to receive the driver's first braking operation on the brake pedal when the current output torque of the electric vehicle is a negative torque;

[0102] The first control module 202 is configured to control the negative torque output by the electric vehicle to decrease or remain unchanged in response to the first braking operation.

[0103] optional, such as image 3 As shown, the electric vehicle 200 also includes:

[0104] The second receiving module 203 is configured to receive the driver's second braking operation on the brake pedal when the current output torque of the electric vehicle is a positive torque;

[0105] The second control module 204 is configured to control the positive torque output by the electric vehicle to be adjusted to zero torque i...

[0123] See Figure 7 , the electric vehicle 700 includes a memory 701, a processor 702, and a computer program stored on the memory 701 and operable on the processor 702; when the processor 702 executes the program, it realizes:

[0124] When the current output torque of the electric vehicle is a negative torque, receiving the driver's first braking operation on the brake pedal;

[0125] In response to the first braking operation, the negative torque output by the electric vehicle is controlled to decrease or remain unchanged.

[0126] exist Figure 7 Among them, the bus architecture may include any number of interconnected buses and bridges, specifically, one or more processors represented by the processor 702 and various circuits of the memory represented by the memory 701 are linked together. The bus architecture can also link together various other circuits such as peripherals, voltage regulators, and power management circuits, etc., which are well known in the art and t...

Abstract

The invention provides an electric vehicle control method and an electric vehicle, and the method comprises the steps: receiving a first braking operation of a driver for a brake pedal under the condition that the current output torque of the electric vehicle is negative torque; and in response to the first braking operation, controlling the negative torque output by the electric vehicle to be reduced or kept unchanged. Thus, under the conditions that the accelerator pedal and the brake pedal of the electric automobile are stepped down at the same time and the electric automobile outputs negative torque, the brake performance of the electric automobile can be prevented from being reduced, and therefore the safety of the electric automobile is improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicle manufacturing, in particular to an electric vehicle control method and the electric vehicle. Background technique [0002] With the development of automobile manufacturing technology and the improvement of people's quality of life, automobiles have become the main means of transportation in people's daily life. Due to the advantages of energy saving and environmental protection, electric vehicles are gradually replacing traditional fuel vehicles, so as to realize the link energy pressure and reduce environmental pollution. [0003] Among them, during the driving of the electric vehicle, the motor can be controlled to output positive or negative torque according to the depth of the accelerator pedal. When the motor outputs positive torque, the electric vehicle can be accelerated; when the motor outputs negative torque, the electric vehicle can decelerate. And realize energy recovery. How...
