Embodiment 1

[0048] see figure 1 , an adaptive cruise control method comprising:

[0049]Step S1: Obtain the historical active driving data of each preset vehicle speed interval, the historical active driving data includes the opening of the accelerator pedal, the rate of change of the opening of the accelerator pedal, and the initial acceleration of the first vehicle;

[0050] Among them, the preset vehicle speed range is a pre-divided vehicle speed range, which can also be divided according to specific circumstances, such as the first speed range with a speed of 0kph to 30kph, the second speed range with a speed of 30kph to 50kph, and the second speed range with a speed of 50kph to 50kph. The third speed range of 80kph, the fourth speed range of 80kph to 120kph, and the fifth speed range of 120kph to 150kph are not limited in this embodiment; the advantage of dividing the preset speed range is that it can be learned in different speed ranges The driver's acceleration style makes the lea...

Embodiment 2

[0099] see Figure 4 , an adaptive cruise control system comprising:

[0100] The acquisition module 1 acquires historical active driving data of each preset vehicle speed interval, the historical active driving data includes accelerator pedal opening, acceleration accelerator pedal opening rate of change, and the initial acceleration of the first vehicle;

[0101] The adjustment module 2 adjusts the initial torque value and the torque change rate according to the historical active driving data;

[0102] The request module 3 generates a requested torque for adaptive cruise control based on the adjusted initial torque value and the torque change rate.

[0103] The adaptive cruise control system of the present disclosure can adjust the requested torque of the adaptive cruise system according to the accelerator pedal opening, pedal opening change rate and initial acceleration when the driver accelerates, so that the acceleration mode of the adaptive cruise control is closer to d...

Embodiment 3

[0135] A computer-readable storage medium, on which a computer program is stored, and when the computer program is executed by a processor, the steps of any one of the adaptive cruise control methods in Embodiment 1 are implemented. It is possible to adjust the requested torque of the adaptive cruise control system according to the accelerator pedal opening, pedal opening change rate and initial acceleration when the driver is accelerating, so that the acceleration mode of the adaptive cruise control is closer to the driver's own acceleration style, so as to meet different needs. Type driver's requirements for acceleration response.

Abstract

In order to solve the problem that the existing adaptive cruise control system cannot meet the acceleration response requirements of different customers due to the single acceleration style, the present disclosure provides an adaptive cruise control method and system to meet the acceleration response requirements of different customers . The method includes: obtaining historical active driving data of each preset vehicle speed range, the historical active driving data including the opening degree of the accelerator pedal, the rate of change of the opening degree of the accelerator pedal and the initial acceleration of the first vehicle; adjusting the torque initial value and torque rate of change; based on the adjusted torque initial value and torque rate of change, a requested torque for adaptive cruise control is generated. The application also discloses a corresponding system and a computer-readable storage medium, which can self-learn the driver's acceleration style to meet the acceleration response requirements of different customers.

Description

technical field [0001] The present disclosure relates to the field of cruise control, in particular to an adaptive cruise control method and system. Background technique [0002] The adaptive cruise control system calculates and obtains the current acceleration according to the surrounding environment of the vehicle and the driver's driving intention, and calculates the required torque according to the actual acceleration value of the current vehicle, and inputs the torque to the EMS controller. And the EMS controller adjusts the response of the engine according to the output torque to complete the external output of torque and the acceleration response of the whole vehicle. [0003] However, the torque request and rate of change of the current adaptive cruise control system are calibration values, and the corresponding acceleration style is relatively simple, which cannot meet the requirements of different customers for acceleration response.
