Problems solved by technology

However, the area that can be driven is judged by the control device based on the position information. When it does not match the driver's sensibility (for example, the speed when passing near obstacles is high, etc.), there are cases where the driver feels uncomfortable.

Embodiment 1

[0046]figure 1 In order to show the configuration of a vehicle including the vehicle control device 324 in the first embodiment of the present invention.

[0047]The vehicle 300 includes a driving force generating mechanism 310, a brake 311, and a transmission 312, the driving force generating mechanism 310, powered by a power source, the brake 311 brakes the vehicle, and the transmission 312 has a driving force in the appropriate direction. 310 The driving force generated by the vehicle is advanced or retracted. The output of the transmission 312 causes the left and right wheels 314 to rotate the vehicle 300, and the vehicle 300 is generated by controlling the brake 311 to decelerate the vehicle 300.

[0048]The driving force generating mechanism 310 can be a hybrid mechanism of an engine or an engine and a motor, or a motor monomer. The vehicle 300 has a steering wheel 313, and the steering angle of the wheel 314 is changed by operating the steering wheel 313, and the vehicle 300 turns....

Embodiment 2

[0165]Embodiment 2 illustrates an example of the setting processing of the driver's operational intervention information 450 of the step 505 shown in the first embodiment.Figure 12 A flowchart of an example of setting processing representing a driving intervention area based on the driver's operation intervention information. This processing instead of the Example 1Figure 6 Execute it.Figure 13 A top view of an example of the set travel path. Furthermore, other configurations are the same as those of the first embodiment.

[0166]Figure 12 In step S801, the path generation unit 403 selects into a change target based on the position and angle of the vehicle 300, which has occurred the intervention of the driver's driving operation, and the travel direction before the driver's operation involved. The line segment of the travel area 104.

[0167]In step S802, as in the first embodiment, the path generation unit 403 sets the predetermined distance R (radius R) from each vehicle end point 704....

Embodiment 3

[0183]Embodiment 3 illustrates an example of the setting process of the driver's operational intervention information 450 of the step 505 shown in the first embodiment.Figure 14 A flowchart of an example of setting processing representing a driving intervention area based on the driver's operation intervention information. This processing instead of the Example 1Figure 6 Execute it.Figure 15 A top view of an example of the set travel path. The processing of steps S801 to S804 and the Example 1Figure 6 the same. Furthermore, other configurations are the same as those of the first embodiment.

[0184]The path generating unit 403 can determine whether or not the driver's operational intervention information 450 is replaced according to the comparison of the state information of the vehicle in the automatic parking history information 460 described in the automatic parking history information 460, as described in the first embodiment. set. In other words, the path generating unit 403 chang...

Abstract

The present invention reduces intervention in automatic parking by a driving operation by a driver. Provided is a vehicle control device which has a processor and a memory, is mounted in a vehicle, and controls the vehicle to arrive at a target parking position, the vehicle control device comprising: an obstacle detection unit that detects the position of an obstacle around the vehicle; a travelable area setting unit that sets, as a travelable area, an area in which the vehicle can travel on the basis of the position of the obstacle and sets the target parking position within the travelable area; a path generation unit that calculates a travel path to the target parking position within the travelable area; and an automatic parking execution unit that causes the vehicle to travel automatically toward the target parking position on the basis of the travel path. If there is intervention in the automatic driving by means of a driving operation by a driver, the path generation unit stores the vehicle state information at the time of the intervention in driver operation intervention information and resets the travelable area on the basis of the driver operation intervention information.

Description

Technical field[0001]The present invention relates to a vehicle control device for assisting a parking space.Background technique[0002]The industry has developed a advanced driving assistance system for preventing driving loads such as traffic accidents and drivers such as traffic accidents. As one of the advanced driving assistance systems, there is an automatic parking. The automatic parking is that if the driver specifies the target parking position, it is automatically accelerated, brake, and a part or all of the vehicle's control devices are automatically accelerated, and the vehicle is stopped.[0003]The vehicle provided automatically in the automatic parking is first installed with a camera or ultrasonic sensor such as a camera or ultrasonic sensor such as a peripheral environment of the vehicle. The control device is based on the position information (sensor information) of the obstacle (resident vehicle, the like) acquired from the sensing device. Calculate the area where yo...
