Abstract

Systems and method are provided for carwash detection and entry assistance of a vehicle. A system includes a controller that operates to identify the presence of the vehicle at a wash facility, and to determine whether an operator of the vehicle has accepted entry assistance. When the operator has accepted entry assistance, the controller prepares the vehicle for entering the wash facility, determines a path into the wash facility, and assists the operator in entering the vehicle into the wash facility via the path.

First claim

What is claimed is:

1 . A system for carwash detection and entry assistance of a vehicle, the system comprising a controller in the vehicle configured to:
identify the presence of the vehicle at a wash facility; determine whether the vehicle is operating in an autonomous mode; prepare, when the vehicle is operating in the autonomous mode, the vehicle for entering the wash facility; determine, when the vehicle is not operating in the autonomous mode, whether an operator of the vehicle has accepted entry assistance; when the operator has accepted entry assistance, prepare the vehicle for entering the wash facility; determine a path into the wash facility; determine, when the vehicle is not operating in the autonomous mode, operation of the vehicle based on operator inputs and assist the operator in entering the vehicle into the wash facility via the path, including by prompting the operator to follow instructions in manually operating the vehicle; operate, when the vehicle is operating in the autonomous mode, the vehicle into the wash facility via the path; control an actuator of the vehicle to align the vehicle in the wash facility using the path; prepare the vehicle for entering the wash facility by moving components of the vehicle to predetermined positions compatible with entering the wash facility and disable park assist warning messages to not provide feedback to the operator of the vehicle when in the wash facility; determine when the vehicle has exited the wash facility; and when the vehicle has exited the wash facility, return the components of the vehicle to a prewash state which is a position of the components of the vehicle before entering the wash facility.

2 . The system of claim 1 , wherein the predetermined positions include setting an infotainment system of the vehicle to presets.

3 . The system of claim 1 , wherein the controller is configured to operate a steering actuator of the vehicle to align the vehicle in the wash facility using the path.

4 . The system of claim 1 , wherein the controller is configured to identify attributes of the wash facility for use in determining the path, including whether the wash facility is a conveyor type or a gantry type, and the controller is configured to control differently for the conveyor type versus the gantry type.

5 . The system of claim 1 , wherein the controller is configured to:
not provide the entry assistance when it is determined that the operator has not confirmed engagement of the entry assistance, and allow the operator to control the vehicle without the entry assistance; determine, when the vehicle is not operating in the autonomous mode, whether an operator of the vehicle has accepted the entry assistance, including by prompting the operator to confirm engagement of the entry assistance; and when it is determined that the operator has not confirmed engagement of the entry assistance, allow the operator to control the vehicle without the entry assistance.

6 . The system of claim 1 , wherein the controller is configured, through an interface, to alert the operator to release a steering system so that the controller steers the vehicle.

7 . The system of claim 1 , comprising:
a sensor system configured to sense a location of a rail of the wash facility; and an actuator system configured to operate components of the vehicle, wherein the controller is configured to determine the path based on the location of the rail and to move, by the actuator system, the vehicle into the wash facility along the path.

8 . The system of claim 1 , comprising an interface configured to display information for the operator, wherein the controller is configured to display the path on the interface.

9 . The system of claim 1 , comprising a sensor system including a speed sensor, and a transmission of the vehicle, wherein the controller is configured to:
sense, via the sensor system, attributes of the wash facility; determine, via the speed sensor, a speed of the vehicle; and shift the transmission to one of a park state or a neutral state, a function of the sensed attributes, when the speed of the vehicle is a zero speed.

10 . The system of claim 1 , wherein the controller is configured to compute steering angles to result in placing wheels of the vehicle on a conveyor of the wash facility.

11 . A method for carwash detection and entry assistance, the method comprising:
identifying, by a controller in a vehicle, the presence of the vehicle at a wash facility; determining, by the controller, whether the vehicle is operating in an autonomous mode; preparing, by the controller and when the vehicle is operating in the autonomous mode, the vehicle for entering the wash facility; determining, by the controller and when the vehicle is not operating in the autonomous mode, whether an operator of the vehicle has accepted entry assistance; preparing, when the operator has accepted the entry assistance, the vehicle for entering the wash facility; determining, by the controller, a path into the wash facility; determining, by the controller and when the vehicle is not operating in the autonomous mode, operation of the vehicle based on operator inputs; assisting, by the controller controlling an actuator of the vehicle, the operator with the vehicle entering the wash facility via the path; not providing the entry assistance, by the controller and when it is determined that the operator has not confirmed engagement of the entry assistance, and allowing the operator to control the vehicle without the entry assistance; determining, when the vehicle is not operating in the autonomous mode, whether the operator of the vehicle has accepted the entry assistance, including by prompting the operator to confirm engagement of entry assistance; and when it is determined that the operator has not confirmed engagement of the entry assistance, allowing, by the controller, the operator to control the vehicle without the entry assistance.

12 . The method of claim 11 , comprising preparing, by the controller, the vehicle for entering the wash facility by moving components of the vehicle to predetermined states compatible with entering the wash facility, wherein the predetermined states include setting an infotainment system of the vehicle to presets.

13 . The method of claim 11 , comprising operating, by the controller, a steering actuator of the vehicle to align the vehicle in the wash facility using the path.

14 . The method of claim 11 , comprising identifying, by the controller, attributes of the wash facility for use in determining the path, including determining whether the wash facility is a conveyor type or a gantry type, and controlling differently for the conveyor type versus the gantry type.

15 . The method of claim 11 , comprising computing, by the controller, steering angles to result in placing wheels of the vehicle on a conveyor of the wash facility.

16 . The method of claim 11 , comprising alerting, by the controller through an interface, the operator to release a steering system so that the controller steers the vehicle.

17 . The method of claim 11 , comprising:
sensing, by the controller via a sensor system, a location of a rail of the wash facility; operating, by the controller via an actuator system, components of the vehicle; determining, by the controller, the path based on the location of the rail; and moving, by the controller via the actuator system, the vehicle into the wash facility along the path.

18 . The method of claim 11 , comprisi
