Vehicle Speed Control Start With Automatic Prerequisite Enabling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving support devices may fail to initiate vehicle speed control when prerequisite controls are disabled, requiring manual enabling of these controls.
Innovation Solution
A driving support device comprising a vehicle speed controller, a system controller, and a storage device, which determines the enablement status of prerequisite controls and automatically enables them if permitted, allowing vehicle speed control to commence without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle speed control is started only when prerequisite control is enabled, then the control safety is improved, but the ease of operation deteriorates
Solution Approach 1:
The system performs preliminary actions by automatically enabling prerequisite controls before vehicle speed control is started, based on pre-stored permission information. This eliminates the need for manual enabling operations while maintaining safety requirements.
Solution Approach 2:
The system serves itself by automatically checking the enablement status of prerequisite controls and enabling them if permitted, without requiring user intervention. The vehicle speed controller autonomously manages the prerequisite control states based on stored permissions.
2Reliability
If manual operation is required to enable prerequisite control, then the control reliability is improved, but the productivity deteriorates
Solution Approach 1:
Permission information regarding whether prerequisite controls can be automatically enabled is determined and stored in advance in the storage device. This preliminary preparation allows the system to quickly automatically enable controls when needed, improving productivity without compromising reliability.
Solution Approach 2:
The vehicle speed controller automatically enables prerequisite controls based on stored permission information, eliminating the need for manual operations. This self-service capability increases productivity by reducing the number of steps required to start vehicle speed control while maintaining control reliability through permission-based automation.

AI summary
The driving support device includes: a vehicle speed controller configured to perform vehicle speed control, a system controller configured to perform at least one prerequisite control, and a storage device configured to store whether or not switching between enabling and disabling is permitted for each of the at least one prerequisite control, wherein the vehicle speed controller includes: determining whether each of the at least one prerequisite control is enabled or disabled in response to an operation of a driver of the vehicle for starting the vehicle speed control, determining, with reference to the storage device, whether or not enabling of the prerequisite control determined to be disabled is permitted, and in response to determining that enabling of the prerequisite control determined to be disabled is permitted, enabling the prerequisite control determined to be disabled and starting the vehicle speed control.
