Valet Mode Driving Evaluation for EV and HEV Parking Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valet modes in vehicles lack detailed control and do not consider the characteristics of Electric Vehicles (EVs) or Hybrid Electric Vehicles (HEVs), leading to unnecessary engine starting due to conditions like heating of an engine catalyst or air conditioning.
Innovation Solution
An eco-friendly vehicle and method for evaluating valet mode driving that quantifies a valet driving evaluation score based on driving evaluation factors, such as wheel speed change, slope, and engine starting frequency, to guide the vehicle for stable and safe parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If general valet mode is activated with simple on-off control, then personal information protection is improved, but detailed control of valet mode depending on the situation cannot be achieved
Solution Approach 1:
The patent segments the valet mode control into multiple independent factors including wheel speed change factor, slope factor, and engine starting frequency factor. Each factor can be independently evaluated and controlled, allowing detailed situational control while maintaining information security. The segmentation enables the system to address specific driving conditions separately rather than using a single on-off switch.
2Device complexity
If simple on-off valet mode control is used, then system complexity is reduced, but unnecessary engine starting occurs due to conditions like heating of engine catalyst or air conditioning
Solution Approach 1:
The patent changes the control parameters from a simple binary on-off state to a multi-dimensional evaluation system that considers wheel speed change, slope, and engine starting frequency. By monitoring and responding to specific parameter changes in the driving environment, the system can make informed decisions about engine starting, preventing unnecessary energy consumption while maintaining manageable system complexity through standardized evaluation criteria.
3Adaptability or versatility
If valet mode does not consider EV or HEV characteristics, then universal applicability is improved, but eco-friendly vehicle specific requirements are not met
Solution Approach 1:
The patent creates a universal evaluation system that can adapt to different vehicle types including EVs and HEVs. The multi-factor evaluation approach (wheel speed change, slope, engine starting frequency) provides a framework that works across vehicle types while allowing specific adjustments for eco-friendly vehicles. The system monitors engine starting frequency specifically, which is crucial for HEVs, while maintaining broad applicability to various vehicle configurations.

AI summary
Disclosed may be a method for evaluating valet mode driving of a vehicle. The method includes determining whether or not a valet mode entry condition may be satisfied, determining a plurality of driving evaluation factors for valet parking based on at least one of a vehicle status or a driving environment, upon determining that the valet mode entry condition may be satisfied, calculating a valet driving evaluation score by analyzing the determined driving evaluation factors and collecting result values acquired through analysis, and displaying the calculated valet driving evaluation score.
