摘要： A diagnostic method for an automated vehicle includes monitoring data from a first vehicle subsystem of a plurality of vehicle subsystems to establish a current operating zone for the first vehicle subsystem, transmitting a master diagnostic message with an anomalous status for the first vehicle subsystem in response to the current operating zone for the first vehicle subsystem being outside of an anomalous behavior boundary of a normal operating zone for the first vehicle subsystem for at least a predetermined period of time, the common master diagnostic message being transmitted to each vehicle subsystem of the plurality of vehicle subsystems, and adjusting operation of at least a second one of the plurality of vehicle subsystems in response to receiving the master diagnostic message with the anomalous status for the first vehicle subsystem. A related diagnostic system is also provided.

摘要： An apparatus for controlling a vehicle has a first actuator for turning a first set of steerable vehicle wheels connected with a first axle of the vehicle. The first actuator turns the first set of steerable vehicle wheels connected with the first axle to cause the vehicle to turn and travel along a desired path. A second actuator turns a second set of steerable vehicle wheels connected with a second axle of the vehicle. A third actuator turns a third set of steerable vehicle wheels connected with a third axle of the vehicle. A control unit controls the second and third actuators connected with the second and third axles to turn the second set of steerable vehicle wheels and the third set of steerable vehicle wheels. The control unit may control the second and third actuators in response to a signal from a sensor to turn the second set and third set of steerable vehicle wheels connected with the second and third axles to eliminate, reject or reduce the yaw moment and lateral force acting on the vehicle due to an aerodynamic force.

摘要： A method for controlling a steering system of a vehicle during an autonomous steering development mode may include performing, by one or more computing devices, high-authority autonomous steering control of a steering system of the vehicle. The method may further include receiving, by the one or more computing devices, an input from at least one sensor of the steering system indicative of manual operation of the steering system by an operator of the vehicle. Additionally, the method may include transitioning, by the one or more computing devices, from the high-authority autonomous steering control to a low-authority autonomous steering control of the steering system for a predetermined time period in response to receiving the input from the at least one sensor.
