Problems solved by technology
[0003] However, due to the setting of the energy recovery system, manufacturers often make the braking time of single-pedal vehicles longer in order to recover the braking energy to a greater extent.
Especially when the vehicle speed is low, due to the small braking force of the motor at this time, the braking time is long, the braking efficiency is low, and the driving experience is far inferior to that of traditional cars, which reduces the user experience

The invention provides a control method and device for a single-pedal vehicle and the single-pedal vehicle. The control method of the single-pedal vehicle includes: obtaining the real-time working state of the accelerator pedal of the car; When currently in a non-accelerated state where the driving force is zero, obtain the first real-time vehicle speed of the car; when the first real-time vehicle speed is less than a first preset value, control the body electronic stability system ESP of the car The car's braking system performs the braking. In the embodiment of the present invention, by acquiring the real-time working state of the accelerator pedal, when it is judged according to the real-time working state that it is currently in a deceleration state, and when the real-time vehicle speed is less than the first preset value, the ESP is controlled to brake the brake system of the car , so as to improve the braking efficiency and make up for the problem of low braking force and low efficiency of the motor at low speed.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a control method and device of a single-pedal automobile and a single-pedal automobile. Background technique [0002] With the development of automobile technology, a single-pedal vehicle with a single-pedal driving mode has appeared in the related art. Its working principle is that after releasing the accelerator pedal, the braking system will intervene and recover kinetic energy through the energy recovery system, thereby realizing vehicle deceleration. and braking. [0003] However, due to the setting of the energy recovery system, manufacturers often make the braking time of the single-pedal vehicle longer in order to recover the braking energy to a greater extent. Especially when the vehicle speed is low, the braking time is long, the braking efficiency is low, and the driving experience is far inferior to that of traditional cars, which reduces the user experience.
