Abstract

Embodiments of the present invention provide a controller ( 10 ) for controlling movement of a vehicle ( 100 ), and a corresponding method. The controller ( 10 ) comprises processing means configured to: receive ( 501 ) a first signal indicative of the vehicle being in a remote control drive mode; receive ( 502 ) a second signal indicative of operation of a main input device ( 124 S, 161, 163, 171, 174 ) within the vehicle ( 100 ); and provide ( 520 ) an output signal for applying a braking force to slow the vehicle ( 100 ) to a stop in dependence on said first and second signals.

Claims (30)

1. A method of controlling movement of a vehicle, comprising:

receiving a first signal indicative of the vehicle being in a remote control drive mode;

receiving a second signal indicative of operation of a main input device within the vehicle;

providing at least one output signal for terminating the remote control drive mode and automatically applying a braking force to slow the vehicle to a stop in dependence on said second signal being received while said first signal indicates the vehicle to be in the remote control drive mode;

while the vehicle is being automatically slowed to the stop, determining whether the second signal is indicative of operation of a main input device of a first class or a second class; and

while the vehicle is being automatically slowed to the stop, permitting an operation requested by the second signal when the main input device is of the first class and denying an operation requested by the second signal when the main input device is of the second class.

2. The method of claim 1 , wherein applying the braking force to slow the vehicle comprises following a predetermined deceleration profile.

3. The method of claim 2 , wherein the predetermined deceleration profile comprises a constant rate of deceleration.

4. The method of claim 1 , wherein the main input device of the second class comprises a throttle, a gear shifter, a clutch, a steering device or a cruise control increase set speed button.

5. The method of claim 1 , wherein the main input device of the first class comprises a steering device, and the operation requested by the second signal is a a steering action.

6. The method of claim 1 , wherein the main input device comprises a service brake or an electronic parking brake and wherein a braking action requested by the second signal is permitted if the requested braking force exceeds the braking force that is automatically applied in dependence on the output signal.

7. The method of claim 1 , comprising, after the vehicle has been brought to a stop:

applying a parking brake of the vehicle; and

putting a transmission of the vehicle into park mode.

8. A non-transitory storage medium containing a computer program configured to be executed by a processor to perform the method of claim 1 .

9. A controller for controlling movement of a vehicle, the controller comprising an electronic processor configured to:

receive a first signal indicative of the vehicle being in a remote control drive mode;

receive a second signal indicative of operation of a main input device within the vehicle;

provide at least one output signal for terminating the remote control drive mode and automatically applying a braking force to slow the vehicle to a stop in dependence on said second signal being received while said first signal indicates the vehicle to be in the remote control drive mode;

while the vehicle is being automatically slowed to the stop, determining whether the second signal is indicative of operation of a main input device of a first class or a second class; and

while the vehicle is being automatically slowed to the stop, permitting an operation requested by the second signal when the main input device is of the first class and denying an operation requested by the second signal when the main input device is of the second class.

10. The controller of claim 9 , comprising a brake controller operably connected to the electronic processor, the brake controller being configured to

output said second signal to the electronic processor based upon operation of at least one brake of a service brake and a parking brake, and

responsive to the at least one output signal from the electronic processor, to control operation of brakes of the vehicle to apply said braking force.

11. The controller of claim 9 , comprising a steering controller that is configured to output said second signal to the processing means based upon operation of a steering device.

12. The controller of claim 11 , wherein the steering device comprises a steering wheel and wherein the steering controller comprises an electric power assisted steering module that is configured to output said second signal in dependence on a predetermined torque having been applied to the steering wheel.

13. The controller of claim 12 , wherein the steering controller is configured to limit any requested steering torque from a remote control device to 3 Nm at the steering wheel in dependence on said predetermined torque having been applied to the steering wheel.

14. The controller of claim 9 , comprising a transmission controller that is configured to output said second signal to the electronic processor based upon operation of one or more of a gear shifter and a clutch.

15. The controller of claim 9 , comprising a powertrain controller that is configured to output said second signal to the electronic processor based upon operation of one or both of a throttle and a cruise control increase set speed button.

16. A vehicle comprising the controller of claim 9 .
