System for assisting a driver to get in and out of a vehicle

1 . A system for assisting a driver to get in and out of a vehicle, said system comprising a steering device comprising: a steering column having a longitudinal axis about which the steering column may pivot, said steering column being connected to a steering wheel, and a force feedback module fixed to the steering column, said force feedback module comprising a controller capable of calculating a force and an actuator capable of applying said force to the steering column so as to cause the steering column to pivot about the longitudinal axis in order to guide the steering column connected to the steering wheel in a predetermined position when a driver is getting in and out, locking the steering column connected to the steering wheel in the predetermined position when a driver is getting in and out.

2 . The assistance system according to claim 1 , comprising at least one sensor configured to detect when a driver is getting in and/or out of a vehicle.

3 . The assistance system according to claim 2 , wherein the at least one sensor is located in a safety belt disposed on a driver's seat of a vehicle, in a driver's seat of a vehicle, in a door of a vehicle or is connected to the shut-down or start-up system of a vehicle.

4 . A vehicle comprising an assistance system making it easier for a driver to get in and out of a vehicle according to claim 1 , an electronic control unit (ECU), a driver's seat, a safety belt disposed on a driver's seat, a door, a shut-down and start-up system of a vehicle.

5 . The vehicle according to claim 4 , wherein the controller is connected to the ECU or integrated directly into the ECU.

6 . A method for assisting a driver to get in and out of a vehicle according to claim 4 , said method comprising:

A. detecting when the driver is getting in or out of the vehicle and

B. calculating a force by the controller and applying said force by the actuator on the steering column so as to cause the steering column to pivot about the longitudinal axis of the steering column in order to guide the steering column connected to the steering wheel in a predetermined position when a driver is getting in and out and

C. blocking the steering wheel in the predetermined position using the controller when a driver is getting in and out of the vehicle.

7 . The method according to claim 6 , wherein in step A), the detection of when a driver is getting in is performed when the vehicle is unlocked and the detection of when the driver is getting out is performed when the vehicle is shut-down.

8 . The method according to claim 7 , wherein in step A), the ECU detects the unlocking of the vehicle.

9 . The method according to claim 7 , wherein the method comprises a step D) set between step A) and step B) in which the ECU transmits the unlocking of the vehicle to the controller.

10 . The method according to claim 7 , wherein in step A), the detection of the shut-down of the vehicle is carried out by means of a sensor.

11 . The method according to claim 6 , wherein the method comprises a step E) including the detection of when the driver is getting in or out of the vehicle by using at least one sensor.

12 . The method according to claim 11 , wherein the detection of when the driver is getting in or out of the vehicle is transmitted by the sensor to the ECU.

13 . The method according to claim 6 , wherein the method comprises a step F) including the unblocking of the steering wheel from the predetermined position.

14 . The method according to claim 13 , wherein the ECU transmits to the controller the information indicating that the driver is getting in or out of the vehicle so that the controller unblocks the steering wheel from the predetermined position.
