Abstract:
1. A vehicle control system of the electrically driven vehicle comprising: a motor/generator arranged in a driving system of a drive wheel for driving the drive wheel by powering and carries out electric power generation by regeneration, a drive transmission engagement element arranged between the motor/generator and the drive wheel, a detecting section that detect a driving state and a running state, and a clutch torque control section programmed to carry out the torque control as follows: based on a detection by the detecting section, the clutch torque control section carries out the engagement element slip process so that the driving transmission engagement element is made to slip, and, when the engagement element slip process is carried out, the target motor/generator torque, which is increased from the drive torque of the motor/generator by a clutch slip accelerating torque portion for accelerating slipping of the driving transmission engagement element, is output from the motor/generator, and a drive wheel slip condition determining section that determines whether a condition of a possibility of the drive wheel slipping on a road surface is met; the clutch torque control section programmed to work as follows: when a determination is made that the condition is met in the drive wheel slip condition determining section, the engagement element slip process is carried out here, as compared with the case when a determination is made by the drive wheel slip condition determining section that the condition is not met, the target motor/generator torque from the motor/generator is smaller.
