Embodiment 1

[0030] This embodiment provides an obstacle avoidance control method suitable for automobiles. The driving mode of the automobile includes a manual driving mode and an automatic driving mode. In the manual driving mode, at least the following steps are included:

[0031] S1: Obtain the current speed information of the car based on the sensor module 11, and determine the obstacle information in front of the car based on the obstacle detection module 14;

[0032] S2: The control module 12 detects the driver's manual operation of the steering module 121 and the braking module 122, and the control module 12 generates a first steering control that matches the manual operation based on the driver's manual operation of the steering module and the braking module 122 command and a first brake control command, and generate a first control command according to the first steering control command and the first brake control command;

[0033] S3: The central processing unit 13 generates a s...

Embodiment 2

[0052] This embodiment is a further improvement on Embodiment 1, and repeated content will not be repeated here.

[0053] The control method is under the automatic driving mode: the type of the obstacle in front of the automobile is determined based on the obstacle detection module 14 is a vehicle or a pedestrian; the central processing unit 13 calculates the minimum braking time and the automobile avoidance and obstacle collision avoidance The minimum turning time of object collision; the control module 12 generates a third steering control command and a third braking control command according to the type of obstacle and the minimum turning time, and sequentially controls the braking and steering of the vehicle.

[0054] Preferably, the obstacle detection module 14 can be configured to identify or determine whether the obstacle is a vehicle or a pedestrian. In particular, the obstacle detection module 14 can be configured to detect the width of the obstacle, and when the widt...

Embodiment 3

[0066] This embodiment is a further improvement on Embodiment 1 and Embodiment 2, and repeated content will not be repeated here.

[0067] The present invention also provides an obstacle avoidance control system suitable for automobiles, which at least includes a sensor module 11 , a control module 12 , a central processing unit 13 and an obstacle detection module 14 . The control module 12 includes a steering module 121 and a braking module 122, and the control system is configured to: in the automatic driving mode, obtain the current speed information of the car based on the sensor module 11; determine the obstacle information in front of the car based on the obstacle detection module 14; control The module 12 detects the driver's manual operation of the steering module 121 and the braking module 122, and the control module 12 generates a first steering control instruction and a second steering control command matching the manual operation based on the driver's manual operati...

Abstract

The invention discloses a control method suitable for obstacle avoiding of a car. The method at least comprises the following steps that in a manual driving mode in a car driving mode, on the basis ofa sensor module, car current speed information is obtained; on the basis of an obstacle detection module, obstacle information in front of the car is determined; a control module detects manual operation of a driver for a steering module and a brake module, the control module generates a first steering control instruction and a first brake control instruction on the basis of the manual operationof the driver for the steering module and the brake module, and according to the first steering control instruction and the first brake control instruction, a first control command is generated; a central processor generates a second control command on the basis of the obstacle information and the car current speed information; and in combining with the car current speed information, the obstacleinformation, the first control command, and the second control command, according to the logic mixing manner, a mixed control command is formed, and through the mixed control command, the car is controlled to avoid to obstacles.

Description

technical field [0001] The invention belongs to the technical field of automatic control, in particular to an obstacle avoidance control method and system suitable for automobiles. Background technique [0002] With the rapid development of the economy, cars have become a necessity of life and entered every household. At the same time, the incidence of traffic accidents is also increasing day by day, and people's lives have been seriously threatened. Therefore, vehicle safety has entered people's field of vision. Much attention. [0003] The operation of modern vehicles is becoming more and more automated, and there is an increasing trend to provide driving control systems that reduce the manual effort of the driver. According to the grading system of the SAE International Society of Automotive Engineers (society of Automotive Engineers), SAE autonomous driving is classified as L0-L5, which is divided into six levels according to different degrees, from zero assistance to f...
