METHOD AND APPARATUS FOR FRONT AND REAR DRIVING TORQUE DISTRIBUTION OF VEHICLE, AND VEHICLE - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18342677 Titled 'METHOD AND APPARATUS FOR FRONT AND REAR DRIVING TORQUE DISTRIBUTION OF VEHICLE, AND VEHICLE'
Simplified Explanation
This abstract describes a method for controlling the distribution of driving torque between the front and rear axles of a vehicle. The controlling apparatus uses various parameters, such as the wheel angle and acceleration information, to determine the expected and actual status of the vehicle during steering. Based on this information, the apparatus calculates a correction yawing moment and establishes a mapping relationship between this moment and a torque distribution coefficient. Using this mapping relationship, the apparatus determines the torque distribution coefficient and subsequently calculates the front and rear axle driving torques of the vehicle.
Original Abstract Submitted
In a method for front-rear driving torque distribution of a vehicle, a controlling apparatus determines an expected status parameter existing during steering of a vehicle based on a wheel angle of the vehicle. The controlling apparatus determines a current correction yawing moment based on an actual status parameter existing during the steering of the vehicle and the expected status parameter, and determines a mapping relationship between a correction yawing moment and a torque distribution coefficient based on the wheel angle and acceleration information of the vehicle. The controlling apparatus then determines a torque distribution coefficient of the vehicle based on the current correction yawing moment and the mapping relationship, and determines front and rear axle driving torques of the vehicle based on the torque distribution coefficient of the vehicle.
