AI Technical Summary

Problems solved by technology

[0005] (1) If the automatic driving mode is turned on, manual intervention is required in case of emergencies or malfunctions, such as sudden braking, sharp turns, etc., and the driver generally does not bother to trigger the physical switch to turn the current The automatic driving mode is switched to the manual driving mode, so that the manual operation cannot get the response of the vehicle, resulting in the loss of control of the vehicle and accidents
[0006] (2) Directly switch the automatic driving mode to the fully manual driving mode. From a physiological point of view, people need a certain time to take over and react. The driver may not be fully engaged in the manual driving state from the automatic driving state. The driver may lose control of the vehicle and cause an accident due to the driver's misoperation (for example, the driver accidentally stepped on the pedal, insufficient operation amount, excessive operation amount, etc.)
[0007] In summary, the vehicle control methods disclosed in the prior art have relatively large safety problems

Embodiment 1

[0032] see figure 1 , which is a flowchart of a vehicle control method provided in Embodiment 1 of the present invention, the method includes:

[0033] Step 101, obtaining information on human manipulation of the vehicle;

[0034] Step 102. Determine the driver's intervention intention according to the human manipulation information;

[0035] Step 103: When the vehicle is currently in the automatic driving mode and it is determined that the intervention intention is slow intervention, control the vehicle to reach a predetermined safe state, and transfer the corresponding control right of the vehicle to the driver.

[0036] Preferably, in order to avoid the problem that the vehicle cannot respond when human intervention is required in an emergency or unexpected situation in the automatic driving mode, thereby causing a vehicle accident, the embodiment of the present invention, in the figure 1 In the method flow shown, also comprise following step 104, as figure 2 Shown:

Embodiment 2

[0051] Embodiment 2, vehicle longitudinal control

[0052] In the second embodiment of the present invention, it is possible to control only the acceleration of the vehicle, to control only the deceleration of the vehicle, or to control the acceleration and deceleration of the vehicle.

[0053] aforementioned figure 1 and figure 2 In the shown method, the aforementioned human manipulation information includes longitudinal human manipulation information for manipulating the longitudinal controller of the vehicle. In the foregoing step 102, according to the human manipulation information, the driver's intervention intention is determined, which can be specifically realized through the following steps A1 to A2, such as image 3 shown, including:

[0054] Step A1. Obtain the longitudinal automatic control information calculated and obtained during the automatic driving process of the vehicle to control the longitudinal controller of the vehicle.

[0055] In the embodiment of ...

example 1

[0068] Example 1. Deceleration control

[0069] In Example 1, the longitudinal controller is a brake controller, the aforementioned first value represents the value of the braking degree of the driver manipulating the brake controller for braking, and the second value is calculated by the unmanned driving control unit is a value representing the degree of braking by manipulating the brake controller. The braking degree may refer to the opening and closing degree of the brake pedal, the deceleration value or the engine torque value, which is not strictly limited in this application.

Abstract

The invention discloses a vehicle control method and device and solves the problem that vehicle control has safety hidden trouble in the prior art. The method comprises the following steps: obtaining vehicle manual operation information; according to the manual operation information, determining an intervention intention of a driver; and when a vehicle is in an automatic driving mode at present and the intervention intention is slow intervention, controlling the vehicle to enter a preset safety state and transferring the corresponding control right of the vehicle to the driver. According to the technical scheme, vehicle control safety is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to a vehicle control method and device. Background technique [0002] At present, in the field of automatic driving, the control of the vehicle is realized, including the manual driving mode and the automatic driving mode; In this mode, the driver immediately hands over control of the entire vehicle to the vehicle, and the main control unit of the vehicle makes decisions and controls based on the information returned by the sensor to realize automatic driving. [0003] At present, mainly by setting a physical switch on the vehicle, the driver can choose to turn on the manual driving mode or the automatic driving mode by triggering the physical switch, so as to realize manual control and automatic control of the vehicle. [0004] However, the existing method of controlling the vehicle has the following problems: [0005] (1) If the automatic driving mode is turned on, m...
