Embodiment 1

[0023] Below, refer to Figure 1 ~ Figure 3 Example 1 of the present invention will be described.

[0024] figure 1 It is a schematic configuration diagram of the vehicle control device 100 according to the first embodiment of the present invention.

[0025] Such as figure 1 As shown, the vehicle control device 100 has an automatic / manual driving mode controller 103 . The input to the automatic / manual driving mode controller 103 comes from the driving environment recognition device 101 composed of a camera, radar, GPS sensor, navigation, etc., and is composed of a G sensor, a steering sensor, a vehicle speed sensor, an accelerator opening sensor, and a brake sensor. The vehicle driving state detection device 102, the automatic / manual driving mode switching switch 110 for the driver to select the automatic / manual driving mode, and the driver information input unit 108 for inputting driver information.

[0026] In addition, the automatic / manual driving mode controller 103 in...

Embodiment 2

[0096] In the vehicle control device and the vehicle control method of the second embodiment, the effects listed below are obtained.

[0097] (1) When the driver's accelerator operation is detected on a curve in the automatic driving mode, the passing vehicle speed V0 in the curve and the deceleration start time corresponding to the predetermined deceleration An to obtain the passing vehicle speed V0 are used as correction values , are stored together with the driver information, and for the same driver, the learned correction value is used in subsequent curves with the same curvature.

[0098] Therefore, it is possible to make the curve traveling in the automatic driving mode match the driver's feeling.

[0099] (2) Switch to the manual driving mode by the accelerator operation in the automatic driving mode, and travel in the automatic driving mode when the driver's accelerator operation disappears.

[0100] Therefore, convenience at the time of traveling can be ensured.

...

Embodiment 3

[0135] In the vehicle control device and the vehicle control method of the third embodiment, the effects listed below are obtained.

[0136] (1) When leaving a curve in the automatic driving mode, if the accelerator operation of the driver is detected, the time when the accelerator is started to be stepped on as a correction value of the control parameter when leaving the curve is taken as the acceleration time for leaving the curve, It is stored together with the driver information, and for the same driver, the learned correction value will be used in future curves with the same curvature.

[0137] Therefore, it is possible to match the driving in the automatic driving mode with the feeling of the driver.

[0138] (2) Switch to the manual driving mode by the accelerator operation in the automatic driving mode, and travel in the automatic driving mode when the driver's accelerator operation disappears.

[0139] Therefore, convenience at the time of traveling can be ensured. ...

Abstract

In autonomous driving mode, the learning correction unit (103a) of an autonomous driving mode control unit (103A) references information from a driver information input unit (108) to correct control parameters from a control parameter calculation unit (103b) on the basis of stored control parameter correction values related to a corresponding driver and controls a steering controller (104), a brake hydraulic controller (105), an engine controller (106), and an automatic transmission controller (107). In other words, in the present invention, a driver's operation is learned during autonomous driving mode and the results thereof are reflected on subsequent autonomous driving mode. Accordingly, autonomous driving mode can be better matched with the driver's senses.

Description

technical field [0001] The invention relates to a vehicle control device and a vehicle control method. Background technique [0002] Patent Document 1 discloses a first driving mode with automatic driving and a second driving mode based on the driver's operation, and the control parameters learned in the second driving mode are reflected in the first driving mode, thereby A technology that reflects the driving characteristics of the driver's intention in the first driving mode. [0003] However, in the technology of Patent Document 1, since the driving state is different between the first driving mode and the second driving mode, even if the learning result in the second driving mode is reflected in the first driving mode, it may not meet the requirements. The feeling of the driver.
