Automatic Vehicle Hold Activation Without a Console Start Button
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing automatic vehicle hold systems face challenges in accurately starting and reliably operating due to trigger manner issues and layout design complexities in the center console, leading to driver fatigue and potential accidents.
Innovation Solution
A vehicle control method and apparatus that switches the automatic vehicle hold system based on user instructions, using status information to confirm user intention and avoid false triggering, allowing for reliable operation and simplified layout design by eliminating the need for a dedicated start button.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a dedicated start button is arranged in the center console to enable automatic vehicle hold function, then the function can be activated, but the layout design difficulty increases
Solution Approach 1:
The existing brake pedal is made to serve dual functions: its primary braking function and a secondary function as a trigger for activating the automatic vehicle hold system. When the brake pedal is depressed while the vehicle is stationary, the system interprets this as an activation command for automatic vehicle hold, eliminating the need for a separate start button and simplifying the center console layout.
2Device complexity
If the brake pedal is used to trigger automatic vehicle hold, then the start button is eliminated, but false triggering may occur
Solution Approach 1:
The system applies different response rules to different operational contexts of the brake pedal. When the vehicle is stationary (vehicle speed = 0), depressing the brake pedal triggers automatic vehicle hold activation. However, when the vehicle is moving, the same brake pedal operation only performs its standard braking function. This context-dependent response prevents false triggering while maintaining the simplified control structure.
Solution Approach 2:
The system checks the vehicle's operational state (whether it is stationary or moving) before responding to brake pedal input. By preliminarily determining the vehicle state and then applying the appropriate response rule, the system ensures that automatic vehicle hold is only activated under appropriate conditions, preventing false triggering while maintaining structural simplicity.
3Duration of action of moving object
If automatic vehicle hold is enabled during vehicle movement, then the function provides continuous support, but safety risks increase
Solution Approach 1:
The system implements context-specific functionality where the brake pedal triggers automatic vehicle hold only when the vehicle is stationary. When the vehicle is in motion, the brake pedal performs only its standard braking function. This spatial/contextual differentiation ensures that automatic vehicle hold operates only in safe conditions (stationary state), eliminating safety risks associated with activation during vehicle movement while maintaining continuous support when appropriate.

AI summary
A vehicle control method includes obtaining a first user instruction, where the first user instruction instructs to enable an automatic vehicle hold function; controlling, based on the first user instruction, an automatic vehicle hold system to switch to a wake-up state; obtaining status information of a vehicle; and switching a status of the automatic vehicle hold system based on the status information of the vehicle.
