摘要： A vehicle control device has a processor configured to set a target torque as a target for driver torque at which generation of anti-torque on a steering wheel is to be initiated, based on a reference torque as a reference for driver torque at which generation of anti-torque is to be initiated against the driver torque produced by operation of the steering wheel by a driver, and a current correction value for the reference torque, to count a number of deviations from a lane marking line of a lane in which the vehicle is traveling while the driver torque exceeds the target torque, and to calculate a new correction value for the reference torque based on a correction coefficient that is set based on the number of deviations, wherein the next target torque is set based on the reference torque and the new correction value for the reference torque.

摘要： An operating system for an automated vehicle includes a failure-detector and a controller. The failure-detector detects a component-failure on a host-vehicle. Examples of the component-failure include a flat-tire and engine trouble that reduces engine-power. The controller operates the host-vehicle based on a dynamic-model. The dynamic-model is varied based on the component-failure detected by the failure-detector.

摘要： A system includes a processor and a memory in communication with the processor. The memory has a human-machine interface module having instructions that, when executed by the processor, cause the processor to identify, influenced by sensor data regarding a vehicle and an environment in which the vehicle operates, an event in which the vehicle should perform an autonomous steering maneuver determined by an autonomous driving system. The instructions further cause the processor to, in response to identifying the event, decouple control of a steering rack of the vehicle by a handwheel of the vehicle and lock the handwheel to prevent the handwheel from substantially moving. The instructions further cause the processor to determine, by the autonomous driving system, the autonomous steering maneuver to be performed by the vehicle influenced by an isometric torque input applied to the handwheel and detected by the processor when the handwheel is locked.

摘要： Disclosed are devices, systems and methods related to direct and indirect methods for detecting wind speed and direction during driving. An example method may include estimating, by a processor of a vehicle controller, a speed and a direction of wind movement near the vehicle based on a first sensor output from a wind sensor, or a second sensor output from a non-wind sensor, or a combination of the first sensor output and the second sensor output, wherein a primary purpose of the wind sensor is wind detection, and a primary purpose of the non-wind sensor is different from wind detection, and generating a control output indicative of a vehicle disturbance force resulting from the wind based on the estimated speed and direction of the wind movement.
