Abstract

A vehicle corner module (VCM) is provided for regulating motion of a host vehicle which comprises a vehicle-onboard vehicle-controller. The VCM comprises a sub-frame mountable to a reference frame of the host vehicle; a wheel-hub assembly comprising a wheel-hub; VCM-sub-systems mediating between the sub-frame and the wheel-hub assembly, e.g., a drive subsystem, a steering subsystem, a suspension subsystem and/or a braking subsystem; and an VCM-onboard VCM-controller, comprising one or more processors and a computer-readable medium storing program instructions that, when executed by the one or more processors, cause the one or more processors to establish a communication link with a vehicle-controller, including electronically transferring information about the VCM from the VCM-controller to the vehicle-controller, and to perform, in response to an installation of the VCM on a vehicle, a post-installation validation-process that includes validating the VCM-subsystems and communicating a result of the validating to the vehicle-controller.

First claim

The invention claimed is:

1. A method of replacing a first vehicle corner module (VCM) with a second VCM, each of the first and second VCMs comprising a sub-frame mountable to a vehicle platform, a wheel-hub assembly, a VCM-controller onboard the VCM, and a plurality of subsystems mediating between the sub-frame and the wheel-hub assembly, the plurality of subsystems comprising at least two of a drive subsystem, a steering subsystem, a suspension subsystem and a braking subsystem, the method comprising the following steps:
a. establishing an electronic communication link between the respective VCM-controller of the second VCM and a vehicle-controller onboard the vehicle platform, wherein the establishing includes transferring information about the second VCM from the respective VCM-controller of the second VCM to the vehicle-controller;
b. in response to and contingent upon an installation of the second VCM on the vehicle, completing a post-installation validation that includes validating the respective plurality of subsystems of the second VCM and communicating a result of the validation to the vehicle-controller; and
c. using the communicated result of the post-installation validation to enable or disable post-installation operation of the vehicle.

2. The method of claim 1 , additionally comprising the step of transmitting, to a permission system in an external computer, information about the replacing of the first VCM with the second VCM.

3. The method of claim 1 , wherein the information transmitted to the permission system includes at least two of: respective identifying information of the first and second VCMs; usage information of one or more of the respective plurality of subsystems of the first VCM; and maintenance information of one or more of the respective plurality of subsystems of the first VCM.

4. The method of claim 1 , wherein the electronic communication link between the respective VCM-controller of the second VCM and the vehicle-onboard vehicle-controller is established before the installation.

5. A method of replacing a first vehicle corner module (VCM) of a host vehicle with a second VCM, each one of the first and second VCMs comprising (i) a respective plurality of mechanical subsystems residing entirely on board the VCM to mediate between the respective sub-frame and the respective wheel-hub assembly, the plurality of subsystems comprising at least tow of a drive subsystem, a steering subsystem, a suspension subsystem and a braking subsystem, and (ii) a respective VCM-controller for actuating, in response to incoming electrical signals received from outside the VCM, the respective plurality of mechanical sub-systems, the method comprising:
a. establishing a direct electronic communication link between the VCM-controller of the second VCM and a VCM-controller of another VCM of the host vehicle; and
b. exchanging information between the VCM-controller of the second VCM and the VCM-controller of the other VCM of the host vehicle.

6. The method of claim 5 , wherein the communication link is established before the second VCM is mounted to the host vehicle.

7. The method of claim 5 , wherein the exchanged information includes at least one of operating history and an operating profile of the second VCM.

8. The method of claim 5 , additionally comprising the step of establishing a communication link between the VCM-controller of the second VCM and a vehicle-controller onboard the host vehicle.

9. A vehicle platform comprising:
a. a plurality of vehicle corner modules (VCMs), each VCM comprising a sub-frame mounted to the vehicle platform, a wheel-hub assembly, a VCM-controller onboard the VCM, a plurality of subsystems mediating between the sub-frame and the wheel-hub assembly, the plurality of subsystems comprising at least two of a drive subsystem, a steering subsystem, a suspension subsystem and a braking subsystem; and
b. communication arrangements enabling direct data communication between respective VCM-controllers of at least two VCMs of the plurality of VCMs, the respective VCM-controllers being configured to exchange information therebetween,
wherein each respective VCM-controller comprises one or more processors and a computer-readable medium storing program instructions that, when executed by the one or more processors, cause the one or more processors to regulate, in response to incoming electrical signals received from outside the VCM, actuation of at least one sub-system of the respective plurality of sub-systems of the VCM.

10. The vehicle platform of claim 9 , wherein the exchanged information includes at least one of operating history and an operating profile of a new or replaced VCM.

11. The vehicle platform of claim 9 , wherein the VCM-controllers are configured to provide an operational backup functionality, singly or in combination, for another VCM-controller.

12. The vehicle platform of claim 9 , wherein the VCM-controllers are configured to provide an operational backup functionality, singly or in combination, for the vehicle controller.

13. The vehicle platform of claim 9 , wherein the communications arrangements enable peer-to-peer data communications between respective VCM-controllers of all of the VCMs of the vehicle.

14. The vehicle platform of claim 9 , wherein the respective selected plurality of sub-systems in each VCM of a given pair of opposing VCMs comprises at least three sub-systems.

15. The vehicle platform of claim 9 , additionally including a vehicle-controller onboard the vehicle platform, wherein (i) the communications arrangements enable direct data communications between the vehicle-controller and each one of the respective VCM-controllers, and (ii) the respective VCM-controllers are configured to exchange information with the vehicle-controller.

16. The vehicle platform of claim 9 , wherein the at least two VCMs includes a pair of opposing VCMs.

17. The vehicle of platform of claim 16 , wherein the respective selected plurality of sub-systems in each VCM of a first pair of opposing VCMs is not the same as the respective selected plurality of sub-systems in each VCM of a second pair of opposing VCMs.
