Title:
CONTROL METHOD AND CONTROL DEVICE FOR ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2018/190021
Kind Code:
A1
Abstract:
The present invention addresses the problem of improving drivability when regenerative braking force increases or decreases at the time of a braking deceleration request. In this control method for an FF hybrid vehicle comprising a motor/generator (3) as a drive source, a target deceleration driving force is achieved by coasting regeneration, braking coordination regeneration, and mechanical braking at the time of a braking deceleration request and the regenerative braking force is defined as the sum of the coasting regeneration amount and the braking coordination regeneration amount. When the regenerative braking force increases or decreases, the slope of change in the regenerative braking force is limited so that the mechanical braking force response speed is greater than the speed of change in the regenerative braking force. In addition, when low µ road control for reducing the regenerative braking force on the basis of the occurrence of braking slip is started during braking deceleration, control is performed in order to maintain the slope of the decrease in regenerative braking force at a limited slope (K).
