Vehicle Wake-Up Control for Pre-Ignition Steering Initialization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle systems require several seconds for initialization operations of electric power steering apparatuses after ignition is turned on, causing discomfort to drivers due to immediate operation limitations.
Innovation Solution
A wake-up control apparatus and method that uses a wake-up signal to selectively initialize selected vehicle apparatuses before ignition, allowing the electric power steering apparatus to complete initialization before the ignition is turned on, using a processor to manage power supply and control signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electric power steering apparatus performs initialization operation after ignition is turned on, then the apparatus can be properly calibrated and aligned, but the vehicle operation is delayed causing driver discomfort
Solution Approach 1:
The patent applies preliminary action by performing the initialization operation of the electric power steering apparatus before the ignition is turned on. The processor receives a wake-up signal and initiates the initialization sequence in advance, completing sensor calibration, steering wheel alignment, and internal part checks before the driver needs to operate the vehicle, thus eliminating the delay while ensuring proper initialization.
2Loss of time
If all apparatuses operate in response to wake-up signal before ignition, then initialization can be completed early, but battery power consumption increases
Solution Approach 1:
The patent applies local quality by selectively activating only the electric power steering apparatus for initialization when the wake-up signal is received, rather than activating all vehicle apparatuses. The processor determines which specific apparatus requires initialization and supplies power only to that apparatus, thereby completing initialization early while minimizing unnecessary battery power consumption.
3Manufacturing precision
If the electric power steering apparatus blocks interference during initialization, then calibration accuracy is improved, but the operation is limited and user interaction is restricted
Solution Approach 1:
The patent resolves this contradiction by performing the calibration and alignment operations during the preliminary initialization phase before ignition, when blocking interference is necessary for accuracy. Once initialization is complete, the apparatus transitions to normal operation mode where user interaction is fully enabled, thus achieving both calibration accuracy and operational availability without mutual conflict.

AI summary
The present disclosure relates to a wake-up control apparatus and method for a vehicle. In response to a signal from a remote controller, power is supplied to some apparatuses selected from a plurality of apparatuses as an activation target, and the activation target performs an initialization operation through the supplied power, so that enough preliminary initialization time may be secured to completely perform the initialization operation on the activation target before an ignition of the vehicle is turned on, some of the plurality of apparatuses may be selectively and partially driven to reduce battery power consumption, and when the ignition of the vehicle is turned on, the vehicle may be driven immediately without waiting, which makes it possible to improve user convenience.
