Abstract
A vehicle having a control element for the speed, acceleration or direction of the vehicle, a computing device to generate a command in autonomous driving of the vehicle, and a command controller coupled between the control element and the computing device. In response to the command, the command controller initiates a test of a portion of the memory of the computing device. If the portion of the memory passes the test, the command controller forwards the command for execution via the control element of the vehicle; otherwise, the command controller blocks the command and/or issues a replacement command for the vehicle.
Claims21
A computing device, comprising:
- a memory;
- a logic circuit coupled to the memory and configured to generate, based at least in part on data stored in the memory, a command for execution;
- and
- a controller operable to effectuate the command generated by the logic circuit, wherein the controller is further configured to initiate a test of a portion of the memory, wherein the controller effectuates the command only if the test indicates that the portion of the memory is not damaged.
A vehicle, comprising:
- a sensor;
- a control element operable to adjust acceleration, speed, or direction of the vehicle;
- a memory;
- a logic circuit configured to use the memory to generate a command based at least in part on data from the sensor;
- and
- a controller coupled between the logic circuit and the control element to determine whether to effectuate the command.
A method, comprising:
- generating, based at least in part on data stored in a memory, a command for execution;
- and
- determining, based on a test of a predetermined portion of the memory and in response to the command being generated for execution, whether to provide the command for execution, wherein the command is provided for execution only if the test indicates that the predetermined portion of the memory is not damaged.
