Abstract

A vehicle includes an electric motor and an engine selectively coupled to the electric motor. The vehicle has an electric motor controller configured to, in response to (i) an absence of receiving a motor command signal within a predetermined time, (ii) a battery voltage being below a first threshold and (iii) a motor speed exceeding a second threshold, restrict operation of the electric motor to a limited operating mode and control the electric motor to generate a charging torque for a battery.
