VEHICLE ATTITUDE CONTROL DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18407316 titled 'VEHICLE ATTITUDE CONTROL DEVICE
The vehicle attitude control device described in the abstract includes several key components:
- Vehicle speed detector for detecting the vehicle speed
- Travel road surface condition estimator for estimating the road friction coefficient
- Actual yaw rate detector for detecting the actual yaw rate
- Front wheel steering angle detector for detecting the front wheel steering angle
- Standard yaw rate calculator for setting limits and calculating standard yaw rate
- Yaw moment calculator for generating a yaw moment based on deviations in yaw rate
Potential Applications: - This technology can be applied in advanced driver assistance systems to improve vehicle stability and control. - It can also be used in autonomous vehicles to enhance their ability to navigate various road conditions.
Problems Solved: - Helps in preventing oversteer or understeer situations by controlling the vehicle's yaw rate. - Enhances safety by ensuring optimal vehicle stability during different driving conditions.
Benefits: - Improved vehicle handling and stability - Enhanced safety features for drivers and passengers - Increased efficiency in vehicle control and performance
Commercial Applications: Title: Advanced Vehicle Stability Control System This technology can be utilized by automotive manufacturers to enhance the safety and performance of their vehicles. It can also be integrated into autonomous driving systems to improve overall vehicle control and stability.
Questions about Vehicle Attitude Control Device: 1. How does the standard yaw rate calculator determine the limits for the front wheel steering angle? The standard yaw rate calculator sets limits based on the vehicle speed, road friction coefficient, and rear wheel sideslip angle limit value.
2. What is the significance of the yaw moment calculator in the vehicle attitude control device? The yaw moment calculator generates a yaw moment based on the deviation between the actual yaw rate and the standard yaw rate, helping to correct any discrepancies and maintain vehicle stability.
Original Abstract Submitted
A vehicle attitude control device includes: a vehicle speed detector, detecting a vehicle speed; a travel road surface condition estimator, estimating a road friction coefficient; an actual yaw rate detector, detecting an actual yaw rate; a front wheel steering angle detector, detecting a front wheel steering angle; a standard yaw rate calculator, setting a rear wheel sideslip angle limit value, calculating a front wheel steering angle limit value according to the vehicle speed, the road friction coefficient and the rear wheel sideslip angle limit value, and calculating a standard yaw rate based on the front wheel steering angle and the vehicle speed, in which the front wheel steering angle is limited by the front wheel steering angle limit value; and a yaw moment calculator, generating a yaw moment based on a deviation between the actual yaw rate and the standard yaw rate.
