Abstract:
1. A vehicle, comprising: a traction electric motor coupled to directly drive at least one traction wheel of the vehicle; an electrical power storage device that stores electric power; one or more idling state sensors positioned to sense an idling state of the vehicle; and a controller that receives input from the one or more idling state sensors and controls supply of electric power from the electric power storage device to the traction electric motor, the controller after determining the vehicle is in the idling state, controls supply of a first amount of electric power from the electrical power storage device to the traction electric motor based at least in part on the sensed idling state of the vehicle, the first amount of electrical energy being sufficient to create vibration of the traction electric motor detectible by a user and insufficient to cause the vehicle to exit the idling state.
