TURNING BEHAVIOR CONTROL DEVICE FOR VEHICLE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18363436 titled 'TURNING BEHAVIOR CONTROL DEVICE FOR VEHICLE
Simplified Explanation
The patent application describes a turning behavior control device for a vehicle that includes a yaw rate detection unit, a brake unit, a drive source, and a travel control unit. The travel control unit calculates the deviation between a reference yaw rate and the actual yaw rate detected by the yaw rate detection unit, and controls the braking force and driving force applied to the vehicle during turning based on this deviation.
- Yaw rate detection unit: Detects the actual yaw rate of the vehicle during turning.
- Brake unit: Applies braking force to the turning inner-side rear wheel or front wheel.
- Drive source: Provides driving force to the turning outer-side rear wheel or front wheel.
- Deviation value calculation unit: Calculates the deviation between the reference yaw rate and the actual yaw rate.
- Braking force control unit: Controls the application of braking force based on the deviation.
- Driving force control unit: Controls the application of driving force based on the braking force control unit's output.
Potential applications of this technology: - Vehicle stability control systems - Autonomous driving systems - Advanced driver assistance systems
Problems solved by this technology: - Improving vehicle stability during turning - Enhancing control over understeer and oversteer conditions - Increasing overall safety and performance of the vehicle
Benefits of this technology: - Enhanced vehicle handling and maneuverability - Improved traction and stability on slippery or uneven road surfaces - Increased driver confidence and comfort while driving
Original Abstract Submitted
A turning behavior control device for a vehicle includes a yaw rate detection unit, a brake unit, a drive source, and a travel control unit. The travel control unit includes a deviation value calculation unit that calculates a deviation between a reference yaw rate for determining the degree of understeer during turning of the vehicle and an actual yaw rate detected by the yaw rate detection unit, a braking force control unit that outputs, to the brake unit, a first signal for applying the braking force to a turning inner-side rear wheel or a turning inner-side front wheel when determining that the deviation exceeds a predetermined deviation reference value, and a driving force control unit that outputs, to the drive source, a signal for applying a driving force to a turning outer-side rear wheel or a turning outer-side front wheel when the braking force control unit outputs the signal.
