1. A vehicle comprising:
- a motor configured to provide drive torque and to facilitate regenerative braking; and
a controller configured to;
receive input indicative of a vehicle speed and a battery state of charge (BSOC),disable the drive torque when the BSOC is less than a maximum discharge limit, wherein the maximum discharge limit is between 6% and 3% BSOC, andactivate regenerative braking only when the BSOC is less than the maximum discharge limit and the vehicle speed is greater than a predetermined speed.

Abstract
A vehicle is provided with a motor that is configured to provide drive torque and to facilitate regenerative braking. The vehicle also includes a controller that is configured to receive input that is indicative of a vehicle speed and a battery state of charge (BSOC), and to disable the drive torque when the BSOC is less than a maximum discharge limit. The controller is also configured to activate regenerative braking when the BSOC is less than the maximum discharge limit and the vehicle speed is greater than a predetermined speed.

14. A vehicle system comprising:
-
a controller configured to; receive input indicative of a vehicle speed, a key position and a battery state of charge (BSOC), disable drive torque in response to the BSOC being less than a first discharge limit, activate regenerative braking only in response to the BSOC being less than the first discharge limit and the vehicle speed being greater than a predetermined speed, electrically disconnect a battery from a motor in response to a key position of off, and upon electrically disconnecting the battery, electrically reconnect the battery to the motor in response to the BSOC increasing above a second discharge limit to allow vehicle restart, the second discharge limit being greater than the first discharge limit. - View Dependent Claims (15, 16, 17, 18, 19, 20)
