APPARATUS AND METHOD FOR CONTROLLING VEHICLE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17879168 titled 'APPARATUS AND METHOD FOR CONTROLLING VEHICLE
Simplified Explanation
The patent application describes an apparatus and method for controlling a vehicle, specifically focusing on accurately determining wheel slip based on the friction of the road surface.
- The apparatus includes a driveshaft that transmits drive torque from a drive motor to a wheel.
- A sensor is used to obtain the speed of the vehicle.
- A controller monitors the drive torque and determines the change amount of the drive torque.
- The controller also determines the change in torsion angle of the driveshaft based on the change amount of the drive torque.
- Based on the change in torsion angle, the controller determines whether wheel slip occurs by analyzing the amount of speed change of the drive motor.
Potential applications of this technology:
- Automotive industry: This technology can be implemented in vehicles to improve traction control systems, allowing for safer driving in various road conditions.
- Racing industry: The accurate determination of wheel slip can enhance the performance of racing vehicles, providing better control and stability during high-speed maneuvers.
Problems solved by this technology:
- Accurate determination of wheel slip: The technology addresses the challenge of accurately detecting wheel slip based on the friction of the road surface, ensuring safe driving conditions for the driver.
Benefits of this technology:
- Improved safety: Accurately determining wheel slip allows for better control of the vehicle, reducing the risk of accidents caused by loss of traction.
- Enhanced performance: By accurately detecting wheel slip, this technology can optimize the performance of vehicles, particularly in racing scenarios, leading to improved speed and maneuverability.
Original Abstract Submitted
An apparatus and a method for controlling a vehicle includes a driveshaft that transmits a drive torque generated by a drive motor to a wheel, a sensor that obtains a speed of the vehicle, and a controller that monitors the drive torque to determine a change amount of the drive torque, determines a change in a torsion angle of the driveshaft based on the change amount of the drive torque, and determines whether wheel slip occurs based on an amount of speed change of the drive motor according to the change in the torsion angle of the driveshaft. Accordingly, it is possible to accurately determine wheel slip according to the friction of a road surface, providing safe driving to the driver.
