Title:
ELECTRIC-VEHICULAR CONTROL METHOD, AND ELECTRIC-VEHICULAR CONTROL APPARATUS
Document Type and Number:
Japanese Patent JP2017175853
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a technique for enabling the suppression of a reduction in a disturbance suppression effect due to an influence of a communication delay between plural controllers even in the case of executing stoppage control using the respective controllers.SOLUTION: A control method, for use in an electric vehicle that includes a vehicle control controller for calculating a torque instruction value in accordance with an accelerator operation amount by a driver and a motor controller for controlling a motor on the basis of the aforementioned torque instruction value, includes a stoppage control determination step for determining whether stoppage control for converging a torque instruction value to disturbance torque as a motor rotation speed or a speed parameter is lowered when the electric vehicle comes close to a stop. Further, in the stoppage control determination step, in a case where the stoppage control is determined to be executed, a feedback gain resident in a feedback system is set larger, by the motor controller, than in a case where no stoppage control is determined to be executed.SELECTED DRAWING: Figure 1
