AI Technical Summary

Technical Problem

In the prior art, a vehicle experiences speed jitter when the vehicle is near the maximum speed of the power source, causing the jitter amplitude to become larger and larger and unable to converge, affecting the normal driving of the vehicle.

Method used

When the vehicle enters the anti-shake control mode, the first torque is determined based on the throttle opening, and the required torque is adjusted by obtaining the speed difference of the driving source. The counter and timer are used to determine the shaking situation, and the required torque is calculated to control the vehicle operation and quickly eliminate the shaking.

Benefits of technology

It effectively avoids the aggravation of vibration amplitude and ensures that the vehicle's speed vibration near the maximum speed is quickly eliminated, ensuring normal driving of the vehicle.

Abstract

The application provides a vehicle driving control method, device, electronic equipment and vehicle, comprising determining that the vehicle enters a dithering elimination control mode, determining a first torque based on an accelerator opening degree, and controlling the vehicle to operate based on the first torque; obtaining a first difference between a first shaft speed of a driving source at a current time and a second shaft speed at a first time, and a second difference between the second shaft speed and a third shaft speed at a second time; determining values of a current counter and a first timer based on the first shaft speed, the first difference and the second difference; if it is determined that the demand torque of the driving source needs to be adjusted based on the values of the current counter and the first timer, processing based on the first torque at the current time, the second torque at the first time, the third torque at the second time and the number of times of resetting the first timer to obtain the demand torque, so as to control the vehicle to operate. The application adjusts the torque according to the number of times and the time of dithering to quickly eliminate the speed dithering.
