example 1

[0097] Example 1 is a system that includes a predictive workload component, a routing component, and a notification component. The predicted workload component is configured to determine that at least one portion of the current route contains a high driver workload. The route component is configured to modify the current route to generate an alternate route, wherein the alternate route avoids at least one portion that includes a high driver workload. The notification component is configured to provide an alternate route to the driver or the automated driving system.

[0098] In Example 2, the predictive workload component of Example 1 is configured to determine the current route based on one or more of turns, deceleration events, speed, traffic flow, sun load, road type, lane changes on at least one portion At least one portion of includes high driver workload.

[0099] In Example 3, the predicted workload component of any of Examples 1-2 is configured to determine that at l...

example 10

[0106] Example 10 encompasses a method for reducing the workload of a driver, an automated driving system, or an automated assistance system (eg, navigation system 102 ). The method includes determining a likely route of the vehicle and identifying a portion of the likely route that has a high attention demand on the driver or driving system. The method includes generating an alternate route that avoids the portion of the possible route. The method also includes providing an alternate route to a navigation system or an automated driving system that avoids the portion of the possible route.

[0107] In Example 11, determining the possible route of Example 10 includes based on one or more of the time of day, date, day of the week, appointments scheduled on a calendar, the vehicle's driving history, the driver's driving history, and the passenger's driving history Multiple to identify possible destinations.

[0108] In Example 12, determining the possible route in any of Exampl...

example 16

[0112] In Example 16, the method further includes one or more of: storing the current driver workload as associated with the current location in the driving history; and communicating the current attention needs and the current location over the network for storage in the workload database.

[0113] In Example 17, the method of any of Examples 10-16 further includes determining that a high demand for driver attention is about to occur within the threshold time period, and delaying delivery of the alert to the driver until the demand for attention falls below the threshold.

[0114] Example 18 is a computer-readable storage medium storing instructions that, when executed by the one or more processors, cause the processors to generate one or more tasks for the one or more segments of the first driving route and calculating a cost for the first driving route based on the distance of the first driving route and the one or more workload values ​​of the first driving route. The com...

Abstract

Methods, systems, and apparatuses for automated driving or for assisting a driver and for determining driver workload prediction as a function of a driving route or path are disclosed. A system includes a predicted workload component, a route component, and a notification component. The predicted workload component is configured to determine that at least one section of a current route comprises a high driver workload. The route component is configured to modify the current route to generate an alternate route, wherein the alternate route avoids the at least one section that comprises a high driver workload. The notification component is configured to provide the alternate route to a driver or automated driving system.

Description

technical field [0001] The present disclosure relates generally to methods, systems and devices for autonomous driving or driver assistance, and more particularly to methods, systems and devices for determining driver workload from a driving route or path. Background technique [0002] Automobiles are a vital part of transportation for commercial, government and private entities. Due to the relatively high cost and price of automobiles, as well as the potential hazards to passengers and drivers, driver safety and the avoidance of collisions or accidents are of paramount importance. In some cases, certain areas or sections of roads may have a higher rate of encountering accidents due to road design, environmental factors, or other factors that make driving in those locations more difficult and / or dangerous. Contents of the invention [0003] A system comprising: [0004] a predicted workload component configured to determine that at least a portion of the current route co...
