Abstract

A remote locking system for an autonomous vehicle is disclosed. The locking system has a locking mechanism operably connected to an axle of the vehicle. The locking mechanism is selectively actuatable to prevent a power system from rotating the axle. The locking system also has a control station connected to the locking mechanism through a wireless network. The control station is configured to remotely actuate the locking mechanism. The power system is autonomously controlled by an electronic control system and the locking mechanism is independent from the electronic control system.

First claim

What is claimed is:

1. A locking system for a vehicle, comprising:
a locking mechanism operably connected to an axle of the vehicle, the locking mechanism being selectively actuatable to prevent a power system from rotating the axle; and
a control station connected to the locking mechanism through a wireless network and configured to remotely actuate the locking mechanism,
wherein the locking mechanism includes:
a rotatable member attached to the axle;
a stationary member attached to the vehicle;
a bracket including a C-shaped channel that accommodates a portion of the rotatable member such that a perimeter surface of the portion of the rotatable member is within the C-shaped channel, wherein the bracket has a first side attached to the stationary member;
a controller attached to a second side of the bracket; and
a pin controllable by the controller to extend through the second side of the bracket to penetrate and deform the rotatable member to prevent rotation of the axle by locking the rotating member to the stationary member,

wherein the power system is autonomously controlled by an electronic control system and the controller that controls the pin independent from the electronic control system.

2. The locking system of claim 1 , wherein the controller is configured to selectively actuate the locking mechanism to prevent rotation of the axle.

3. The locking system of claim 2 , wherein the controller is dedicated to actuating the pin.

4. The locking system of claim 1 , wherein the controller is attached to the bracket such that a portion of the bracket is between the controller and the rotatable member.

5. A locking system for a vehicle, comprising:
a locking mechanism mounted on a rotating member attached to an axle of the vehicle, the locking mechanism being selectively actuatable to prevent a power system from rotating the axle; and
a control station connected to the locking mechanism through a wireless network and configured to remotely actuate the locking mechanism,
wherein the locking mechanism is independent from and has no electrical connection or communication path to the electronic control system, and
wherein the locking mechanism includes:
a rotatable member attached to the axle;
a stationary member attached to the vehicle;
a bracket including a C-shaped channel that accommodates a portion of the rotatable member such that a perimeter surface of the portion of the rotatable member is within the C-shaped channel, wherein the bracket has a first side attached to the stationary member;
a controller attached to a second side of the bracket; and
a pin controllable by the controller to extend through the second side of the bracket to penetrate and deform the rotatable member to prevent rotation of the axle by locking the rotating member to the stationary member, wherein the controller is configured to selectively actuate the pin to prevent rotation of the axle.

6. The locking system of claim 5 , wherein the power system is autonomously controlled by an electronic control system and the locking mechanism is independent from the electronic control system.

7. The locking system of claim 6 , wherein the controller is dedicated to actuating the pin.

8. A vehicle, comprising:
a power system including at least one of an engine or a motor configured to rotate an axle;
at least one traction device operably connected to be rotated by rotation of the axle;
an electronic control system configured to control the power system to autonomously drive the vehicle; and
a locking system including a locking mechanism operably connected to the axle and being selectively actuatable to prevent the power system from rotating the axle;
wherein the locking mechanism includes:
a rotatable member attached to the axle;
a stationary member attached to the vehicle;
a bracket including a C-shaped channel that accommodates a portion of the rotatable member such that a perimeter surface of the portion of the rotatable member is within the C-shaped channel, wherein the bracket has a first side attached to the stationary member;
a controller attached to a second side of the bracket; and
a pin controllable by the controller to extend through the second side of the bracket to penetrate and deform the rotatable member to prevent rotation of the axle by locking the rotating member to the stationary member,

wherein the power system is autonomously controlled by an electronic control system and wherein the locking mechanism is independent from and has no electrical connection or communication path to the electronic control system.

9. The vehicle of claim 8 , wherein the controller is configured to selectively actuate the locking mechanism to prevent rotation of the axle.

10. The vehicle of claim 9 , wherein the controller is dedicated to actuating the locking mechanism.

11. The vehicle of claim 9 , wherein the controller is configured to connect with a control station configured to actuate the locking mechanism via a wireless network.

12. The vehicle of claim 11 , wherein the controller communicates with only the control station.
