Abstract

A vehicle coasting deceleration control system has a motor / generator arranged in a drive-train of a vehicle. A controller is configured to determine a driver demand regarding deceleration of the vehicle at a time of coasting accompanied by an accelerator releasing operation. The controller is further configured to control the motor / generator to decelerate the vehicle according to the determined driver demand regarding deceleration.

Description

technical field [0001] The present invention relates generally to vehicles, and more particularly to an in-gear and coast control apparatus and method for a vehicle employing a drive system with a motor generator and a transmission. Background technique [0002] In a motor vehicle with a stepped transmission, the coasting deceleration is affected by the amount of engine friction, depending on the accelerator position or whether the brakes are applied. Also, engine friction may vary with engine revolutions as a function of engine speed or engine revolutions per minute (RPM). In addition, the force transmitted to the rear portion of the transmission due to friction varies with the transmission ratio determined by the shift schedule. [0003] Typically, the coasting deceleration of a vehicle equipped with a stepped transmission is determined when the engine is designed. Therefore, the range of coasting deceleration cannot be adjusted to meet various driving conditions. For e...
