Embodiment 1

[0037] 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:

[0038] 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;

[0039] 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;

[0040] S3: The central processing unit 13 generates a s...

Embodiment 2

[0059] This embodiment is a further improvement on Embodiment 1, and repeated content will not be repeated here.

[0060] 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.

[0061] 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

[0073] This embodiment is a further improvement on Embodiment 1 and Embodiment 2, and repeated content will not be repeated here.

[0074] 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

An automobile driving control method capable of being matched with manual operation at least comprises the following steps that after a driver exerts manual operation on a steering module and a braking module, an automobile does not execute corresponding steering and braking operation, and a control module generates a first steering control instruction and a first braking control instruction matched with the manual operation; and when a driver applies manual operation on the steering module and the braking module, the central processing unit generates a second steering control instruction and a second braking control instruction according to information such as the automobile speed, the obstacle size, the distance between the automobile and the obstacle and the relative speed of the automobile and the obstacle.

Description

[0001] The present invention is a divisional application with the application number 201810933079.1, the application date is August 15, 2018, the application type is invention, and the application name is an obstacle avoidance control method and system suitable for automobiles. technical field [0002] The invention belongs to the technical field of automatic control, and in particular relates to an automobile driving control method and system which can cooperate with manual operation. Background technique [0003] 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. [0004] The operation of modern vehicles is becoming more and more automated, and there is an increasing trend to provide driving control syste...
