Abstract: A vehicle system for a vehicle can include sensors and a controller. The sensors can detect a position and speed of the vehicle and a position and speed of an object adjacent to the vehicle's lane. The controller can determine an operational state based on input from the sensors. The controller can operate the vehicle in an autonomous mode, wherein the controller controls the speed of the vehicle and a spacing between the vehicle and the object. The controller can switch from the autonomous mode to a learning mode in response to a driver taking control of the vehicle's speed or steering. In the learning mode, the controller can learn a preferred spacing between the vehicle and the object and a preferred speed relative to the object. The controller can control the vehicle in the autonomous mode based on the preferred spacing and speed during similar operational states.

Abstract: Systems and methods for operating and hybrid driveline are presented. In one example, driver demand torque may be supplied to vehicle wheels via a hydraulic torque path and a friction torque path. Torque is distributed between the friction torque path and the hydraulic torque path in a way that ensures that driver demand torque is met and the friction torque path transfers torque up to its capacity.

Abstract: When a transmission controller issues a control command, such as pressure to control clutch torque, the response may be delayed due to dynamic properties of the control system. These properties can be modeled using a dynamic response model. One potential model is a combination of a pure time delay and a first order distributed delay. Control methods may be improved in several ways by accounting for the dynamic response. First, the dynamic response model may be used to improve adaptation of a transfer function between the commanded control signal and the clutch torque. Second, the command may be adjusted based on the dynamic response model. Both the pure time delay and the time constant of the first order distributed delay may be functions of operating conditions such as temperature.

Abstract: A driver of a vehicle applies an actuation force to an accelerator device such as an accelerator pedal or a twist-grip throttle of the vehicle to deflect the accelerator device to an actual deflection angle (?act), which is detected. A restoring force acts on the accelerator device opposite the actuation force. An electronic controller determines a nominal deflection angle (?nom) to which the accelerator device shall be deflected, based on inputs such as an actual speed of the subject vehicle, a relative speed of the subject vehicle relative to a leading vehicle driving ahead of the subject vehicle, an actual distance of the subject vehicle to the leading vehicle, and a nominal distance at which the subject vehicle shall follow the leading vehicle. The restoring force on the accelerator device is modulated as a function of the difference between the actual deflection angle (?act) and the nominal deflection angle (?nom).

Abstract: Aspects of the present disclosure include a navigation system and computer-implemented methods for detecting traffic disruption events based on an analysis of input component data obtained from navigation-enabled devices of vehicles near a particular location. Traffic disruption events are events such as accidents, construction road closures, police and speed traps, or road hazards that cause a decrease in the flow of traffic along a particular route and thus, added time delays for occupants of vehicles traveling along those routes. The navigation system scores the input component data associated with each vehicle and aggregates the scored input component data to obtain a frustration score associated with the vehicle. The navigation system may detect traffic disruption events based on a number of vehicles near a particular area having associated frustration scores above a certain threshold.
