Solution Overview
Problem
Existing driving assistance apparatuses face difficulties in effectively assisting with the handling of obstacles during vehicle operation, particularly in adjusting vehicle height to improve footing and alerting the driver in a timely manner.
Innovation Solution
A driving assistance apparatus comprising a vehicle height adjusting mechanism, a progress parameter acquiring unit, and a control section that adjusts vehicle height based on acquired parameters such as distance to a target object, vehicle velocity, and time to collision, allowing for improved footing and timely warnings to the driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle height adjusting mechanism is controlled based on progress parameters (distance, time to collision), then the ability to handle obstacles and improve footing is enhanced, but the device complexity increases due to additional sensors and control logic
Solution Approach 1:
The vehicle height adjusting mechanism is integrated with the existing driving assistance system, allowing it to serve multiple functions: routine height adjustment and obstacle avoidance. The control section utilizes progress parameters (distance to target object, time to collision) that are already being monitored by the driving assistance apparatus, eliminating the need for separate detection systems and reducing overall complexity.
Solution Approach 2:
The patent combines the obstacle detection function with the vehicle height control function. The same sensors and processing units that monitor driving conditions are also used to determine when height adjustment is needed. This merging of functions allows the system to respond to obstacles without adding separate detection and control systems.
2Loss of time
If vehicle height is adjusted in advance based on progress parameters, then the driver is alerted in time and footing is improved, but the response time for sudden obstacles may be insufficient
Solution Approach 1:
The vehicle height adjusting mechanism operates dynamically by continuously monitoring progress parameters and adjusting height in real-time based on the approaching obstacle. The system adapts the timing and magnitude of height adjustments according to the calculated time to collision and distance, allowing for both advance preparation and rapid response to changing conditions.
Solution Approach 2:
The control section calculates progress parameters continuously and initiates height adjustment before the vehicle reaches the obstacle. By using distance and time to collision data, the system performs preliminary height adjustments that prepare the vehicle for upcoming obstacles, giving the driver advance warning while maintaining the capability for rapid final adjustment.
