Vehicle Control Apparatus for Dynamic Traveling Assist
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automated driving systems may provide excessive assist that is not desired by users, particularly in situations where a destination has not been set, leading to uncomfortable driving experiences.
Innovation Solution
A vehicle control apparatus that differentiates between first traveling control with higher assist levels for course changes when a destination is set and second traveling control with lower assist levels for maintaining current route navigation when no destination is set, thereby suppressing unwanted assist.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automated driving control provides traveling assist for course changes when destination is not set, then the automation level is improved, but excessive unwanted assist occurs causing user discomfort
Solution Approach 1:
The patent applies dynamics by making the traveling assist function conditional and variable based on destination setting status. The control unit dynamically adjusts whether course change assist is activated - enabling it when destination is set and disabling it when destination is not set. This dynamic adjustment resolves the contradiction by allowing high automation only when appropriate (destination set) while preventing unwanted assist (user discomfort) when destination is not set.
Solution Approach 2:
The patent changes the parameter of assist activation status based on the destination setting condition. When destination is set, the system parameter for course change assist is set to enabled; when destination is not set, the parameter is set to disabled. This parameter change approach allows the system to provide appropriate automation levels matching user intent, resolving the contradiction between automation level and user comfort.
2Adaptability or versatility
If automated driving control provides traveling assist for course changes, then navigation capability is improved, but excessive assist occurs when not desired by user
Solution Approach 1:
The patent applies preliminary anti-action by checking the destination setting status before activating course change assist. The control unit preemptively prevents unwanted assist by disabling the function when destination is not set, before the user could potentially be disturbed by excessive assist. This preliminary condition check and prevention mechanism resolves the contradiction by ensuring navigation capability is provided only when user intent is clear (destination set).
Solution Approach 2:
The system uses feedback from the destination setting status to control the traveling assist function. The control unit continuously monitors whether a destination is set and adjusts the assist function accordingly - enabling it when destination exists and disabling it when destination is not set. This feedback mechanism ensures navigation capability is provided adaptively, preventing excessive unwanted assist and resolving the contradiction between navigation capability and harmful effects.

AI summary
A vehicle control apparatus for controlling a vehicle, comprising, a setting unit that accepts setting of a destination; an acquisition unit that acquires peripheral information of the vehicle; and a control unit that controls traveling of the vehicle based on the peripheral information, wherein the control unit executes, if the destination has been set, first control in which first assist for a course change is performed in accordance with a case in which the vehicle has entered a course change area from a first road existing on a traveling route to the destination to a second road connected to the first road, and executes, if the destination has not been set, second control in which second assist with an assist level lower than in the first assist is performed on a road existing on a current traveling route.
