Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inertial driving guide systems fail to adjust driving settings for inertial driving when a preceding vehicle is present, leading to inefficient fuel consumption and potential safety issues due to fixed target points and speeds.
Innovation Solution
An inertial driving guide apparatus and control method that compares vehicle information of the current vehicle with that of a preceding vehicle to dynamically change driving settings, including target points and speeds, using creep torque control to adjust vehicle speed without brake input, thereby adapting to the presence of a preceding vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If fixed target points and speeds are maintained for inertial driving guide, then the inertial driving control logic is simple, but fuel efficiency deteriorates and safety issues arise when preceding vehicles are present
Solution Approach 1:
The patent implements dynamic adjustment of target points and target speeds based on real-time detection of preceding vehicles. The controller modifies the inertial driving parameters adaptively: when a preceding vehicle is detected within a threshold distance, the target speed is reduced or target point is relocated, ensuring safe and efficient inertial driving operation under varying traffic conditions.
2Ease of operation
If fixed target points and speeds are used for inertial driving, then the system operation is simple, but safety deteriorates when preceding vehicles require speed reduction
Solution Approach 1:
The patent employs feedback control by continuously monitoring the distance to preceding vehicles and adjusting the inertial driving target parameters accordingly. The controller compares the actual distance with a preset threshold and dynamically modifies target speed or target point based on this feedback, ensuring safe operation while maintaining automated control.
3Adaptability or versatility
If inertial driving guide is provided without considering preceding vehicles, then the navigation function is straightforward, but harmful factors increase due to rapid speed reduction requirements
Solution Approach 1:
The patent applies preliminary action by detecting preceding vehicles in advance and proactively adjusting the inertial driving target parameters before the vehicle needs to rapidly decelerate. The controller predicts potential safety issues and modifies target speed or target point ahead of time, allowing smoother speed transitions and eliminating the need for abrupt braking.

AI summary
An inertial driving guide apparatus and a control method control an inertial driving traveling guide apparatus to change a driving setting for inertial driving if a preceding vehicle is present when an inertial driving guide is provided. The inertial driving guide apparatus includes: a navigation system that outputs a traveling route according to input of a destination of a current vehicle; and a controller for providing the inertial driving guide for the current vehicle according to current traveling road conditions depending on the input route, such that if a preceding vehicle is present in front of the current vehicle when the inertial driving guide for the vehicle is provided, the controller is configured to compare vehicle information on the preceding vehicle with vehicle information on the current vehicle and to change a driving setting for inertial driving of the current vehicle.
