Vehicle with an electrical traction motor and an additional user of electrical energy and method for operation of the vehicle
First Claim
Patent Images
1. A vehicle, comprising:
- at least one electrical traction motor;
at least one additional user of electrical energy;
a vehicle control system; and
a source of electrical energy, the at least one traction motor being effectively connected with the vehicle control system so that in the event of a failure of the source of electrical energy, the vehicle is automatically decelerated in regenerative operation and the at least one additional user is supplied with electrical energy by the at least one traction motor which is operating in a regenerative mode, wherein the at least one additional user is selected from an electric steering system and an electric brake, and wherein the vehicle control system decelerates the vehicle by causing the at least one traction motor to operate in the regenerative mode so that the electrical energy generated by the at least one traction motor is at least sufficient to operate the at least one additional user.

Abstract
A vehicle has at least one electrical traction motor, at least one additional user of electrical energy, a vehicle control system and a source of electrical energy. The traction motor is effectively connected with the vehicle control system so that in the event of a failure of the source of electrical energy, the vehicle is automatically decelerated in regenerative operation and the user is supplied with electrical energy by the traction motor which is operating in the regenerative mode.

5. A method of operating a vehicle, whereby during traction operation, electrical energy is fed by means of a vehicle control system from an electrical energy source into at least one electric traction motor and into at least one additional user, and in the event of the failure of the source of electrical energy during traction operation electrical energy is generated by automatically decelerating the vehicle using the at least one traction motor in regenerative operation, and supplying the at least one additional user with the generated electrical energy, the method comprising:
-
generating electrical energy by the at least one traction motor operating in the regenerative mode and feeding the electrical energy into at least one of an electrically actuated brake and an electrical steering system, wherein the vehicle control system decelerates the vehicle by causing the at least one traction motor to operate in the regenerative mode so that the electrical energy generated by the at least one traction motor is at least sufficient to operate the at least one additional user. - View Dependent Claims (6, 7)
