Garage Mode Speed Control for Narrow-Site Mis-Acceleration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers often lose control of vehicles in cramped spaces due to confusion between the accelerator and brake pedals, leading to accidents, and existing automatic systems are either expensive or passive, causing discomfort and safety concerns.
Innovation Solution
A garage mode control unit that receives vehicle environment and state information to generate control signals, limiting vehicle speed and activating the braking system if necessary, using existing vehicle hardware to prevent erroneous acceleration without increasing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automatic driving systems or automatic parking systems are used to prevent accidental acceleration, then safety is improved, but vehicle cost increases significantly
Solution Approach 1:
The patent changes the control parameters of the vehicle by introducing a garage mode with speed limits (5-20 km/h) and modified accelerator pedal response characteristics. This allows existing hardware to function differently in cramped spaces, providing safety without requiring expensive new systems
Solution Approach 2:
The patent makes existing vehicle control systems multi-functional by enabling them to operate in two distinct modes: normal mode and garage mode. The same accelerator pedal, brake system, and control units serve both standard driving and enhanced safety functions in cramped spaces
2Reliability
If automatic emergency braking system is used to avoid accidental acceleration, then safety is improved, but driver comfort deteriorates due to passive remedial nature
Solution Approach 1:
The patent applies preliminary action by detecting garage environments beforehand and proactively limiting vehicle speed and modifying accelerator response before an accident can occur. This prevents erroneous acceleration rather than reacting to it, avoiding the startling effect of emergency braking
Solution Approach 2:
The patent implements feedback by continuously monitoring vehicle speed, accelerator pedal position, and environmental conditions, then adjusting control parameters in real-time. The system provides gentle feedback through speed limiting and brake assistance rather than abrupt emergency intervention
3Reliability
If garage mode control signal with speed limiting is implemented, then erroneous acceleration is prevented, but existing hardware must be sufficiently utilized without adding expensive components
Solution Approach 1:
The patent applies self-service by having the vehicle's existing control units (engine control unit, brake control unit, transmission control unit) perform the safety function themselves through software control. No additional dedicated safety hardware is required - the existing systems serve the dual purpose of normal operation and garage mode safety

AI summary
The disclosure discloses a garage mode control unit, system and method capable of preventing vehicle miss-acceleration in narrow site. The control method comprises the steps that vehicle environment information is received; whether a vehicle is in the narrow site or not is judged according to the vehicle environment information; and the vehicle is controlled according to a garage mode when the condition that the vehicle is in the narrow site is judged.
