Abstract
A vehicle control system including human-control members generating signals for manual piloting of actuators of the vehicle, an automatic control module generating signals for automatic piloting of the actuators of the vehicle, and a switching module to select the manual-piloting signals in a manual mode of operation and the autonomous-piloting signals in an autonomous mode of operation. The automatic control module includes a block for automatic formulation of at least one calculated autonomous piloting signal and a security block to transmit to the switching module a calculated autonomous piloting signal in a case of normal autonomous operation and an emergency autonomous piloting signal in a case of abnormal autonomous operation.

A vehicle control system comprising:
- manual-control members that generate manual-driving signals to manually drive actuators of the vehicle;
- automatic-control circuitry that generates autonomous-driving signals to autonomously drive the actuators of the vehicle;
- and
- switching circuitry configured to select the manual-driving signals in a manual mode of operation and to select the autonomous-driving signals in an autonomous mode of operation,
- wherein the automatic-control circuitry includes:
- an automatic-formulation circuitry portion that automatically formulates at least one calculated autonomous-driving signal,
- a safety circuitry portion configured to transmit to the switching circuitry the at least one calculated autonomous-driving signal in a case of normal autonomous operation and an emergency autonomous-driving signal in a case of abnormal autonomous operation,
- a supervision module having an overall finite state machine with a first overall state associated with the manual mode of operation and a second overall state associated with the autonomous mode of operation to send the switching circuitry at least one signal to select the manual-driving signals and the autonomous-driving signals,
- wherein the overall finite state machine comprises a third overall state associated with the case of abnormal autonomous operation to send the safety circuitry portion at least one emergency braking signal.
A method for controlling a vehicle comprising:
- executing one or more manual-modes in which manual-control members generate manual-driving signals for manually driving actuators of the vehicle;
- and
- executing, using automatic-control circuitry, one or more autonomous-modes in which autonomous-driving signals are generated and switched toward the actuators of the vehicle in place of the manual-driving signals;
- wherein said executing the one or more autonomous-modes using the automatic-control circuitry includes:
- executing a normal autonomous-mode performed in a case of normal autonomous operation and in which the autonomous-driving signals comprise at least one calculated autonomous-driving signal, and
- executing an emergency autonomous-mode performed in a case of abnormal autonomous operation and in which the autonomous-driving signals comprise at least one emergency autonomous-driving signal,
- wherein the automatic-control circuitry includes a supervision module having an overall finite state machine with a first overall state associated with the manual mode of operation and a second overall state associated with the autonomous mode of operation to send at least one signal to select the manual-driving signals and the autonomous-driving signals, and
- wherein the overall finite state machine comprises a third overall state associated with the case of abnormal autonomous operation to send at least one emergency braking signal.
