US 2026/0298340 A1 · VEHICLE CONTROL SYSTEM

Abstract

A vehicle control system includes a motor that generates torque for driving a vehicle, a power transmission mechanism configured to transmit the torque of the motor to a driving wheel of the vehicle through a plurality of gears, an accelerator opening degree sensor that detects an accelerator opening degree, and a control device configured to calculate a target torque that should be generated from the motor on the basis of at least the accelerator opening degree and control the motor on the basis of the target torque. The control device calculates a predicted backlash angle of the plurality of gears of the power transmission mechanism after a predetermined time when the vehicle switches from a deceleration state to an acceleration state, and temporarily reduces the target torque when the predicted backlash angle becomes equal to a predetermined angle.
