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.
