An automotive vehicle includes at least one sensor configured to detect features in a region proximate the exterior of the vehicle, at least one actuator configured to control vehicle steering, propulsion, shifting, or braking, and an automated driving system selectively operable in a nominal mode and in a degraded mode. The automated driving system is configured to generate an actuator control signal for the at least one actuator in response to sensor signals from the at least one sensor. The automated driving system includes a computational accelerator processor. The vehicle further includes a monitor processor in communication with the automated driving system. The monitor processor is configured to provide a test input for processing by the computational accelerator processor, receive a test output from the computational accelerator processor, and in response to the test output not satisfying a validation criterion, control the automated driving system in the degraded mode.

System and method for hardware verification in an automotive vehicle

A method of controlling a vehicle having an automated driving system configured to control vehicle steering includes determining a commanded vehicle path. The method additionally includes calculating a steering command to satisfy the commanded vehicle path. The method also includes controlling vehicle steering, via the automated driving system, according to the steering command. The method further controls detecting a difference between an actual vehicle path and the commanded vehicle path, and, in response to the detected difference, controlling the vehicle according to a secondary mode.

Diagnostic method for an actuator in an autonomous vehicle

An automotive vehicle includes a vehicle steering system, an actuator configured to control the steering system, a first controller, and a second controller. The first controller is in communication with the actuator. The first controller is programmed with a primary automated driving system control algorithm and is configured to communicate an actuator control signal based on the primary automated driving system control algorithm. The second controller is in communication with the actuator and with the first controller. The second controller is configured to, in response to a first predicted vehicle path based on the actuator control signal deviating from a current lane, control the actuator to maintain a current actuator setting. The second controller is also configured to, in response to the first predicted vehicle path being within the current lane, control the actuator according to the actuator control signal.

Automated lane keeping co-pilot for autonomous vehicles

A method can be used to control a hybrid vehicle and includes the following steps: (a) receiving, via a control module, an input; (b) determining, via the control module, whether the hybrid vehicle is traveling on a highway based, at least in part, on a vehicle speed and an output torque request; (c) commanding, via the control module, the hybrid powertrain to switch from a charge-depletion mode to a blended mode if the hybrid vehicle is traveling on a highway; and (d) commanding, via the control module, the hybrid powertrain to use energy from the energy storage device via the electric motor-generator so as to maintain a substantially constant target state of charge (SOC) discharge rate.
