Systems and methods for efficiently addressing technical and privacy/authorization obstacles associated with tracking of individuals in a vehicle, and enabling route-based analysis to determine driving behavior, socio-demographics, future profitability, and interests of individuals or self-driving systems. Driving information is collected using a device associated with a driver and a vehicle or using data collected by systems of self-driving vehicles. The frequency and methods used for the collection of driving information can be modified based on location and movement of the device and based on previous classification of the driver or self-driving system, thereby enabling efficient use of bandwidth and battery and increasing accuracy of the classification. The driving information is encoded and transmitted to a server, where future typical route segments that the driver is likely to travel are predicted, and the driver, or the self-driving system, is classified into one or more groups based on the encoded driving information.

The present disclosure relates to enabling an autonomous vehicle operating in a self-driving mode to communicate information about what the vehicle is about to do or is currently doing. For example, one or more processors may maneuver a vehicle in an autonomous or self-driving mode. While maneuvering the vehicle in the autonomous driving mode, a time when the vehicle will begin to accelerate may be determined. A first audible signal may be played through a speaker at a time t seconds before the time when the vehicle will begin to accelerate. While maneuvering the vehicle in the autonomous driving mode, a time when the vehicle will begin to decelerate may also be determined. A second audible signal, different from the first audible signal, may be played through the speaker at the time when the vehicle begins decelerating.

Described are a method and a system for localization of a vehicle. The method includes the acquisition of SPR images of a subsurface region along a vehicle track. Acquired SPR images are compared to SPR images previously acquired for a subsurface region that at least partially overlaps the subsurface region along the vehicle track. In some embodiments, the comparison includes an image correlation procedure. Location data for the vehicle are determined based in part on location data for the SPR images previously acquired for the second subsurface region. Location data can be used to guide the vehicle along a desired path. The relatively static nature of features in the subsurface region provides the method with advantages over other sensor-based navigation systems that may be adversely affected by weather conditions, dynamic features and time-varying illumination. The method can be used in a variety of applications, including self-driving automobiles and autonomous platforms.

Additional data continues to be collected on the actual driving behavior, and the custom control is adjusted based upon the collected additional data.

During a self-driving control, when an acquisition failure occurs in traveling environment information acquisition required for performing self-driving, and a failure of a steering system of a vehicle equipped with the vehicle driving control apparatus is detected, a brake controller sets an evacuation course along which the vehicle is to travel safely within traveling environment, based on traveling environment information detected last time before the acquisition failure of the traveling environment information, and executes a deceleration of the vehicle and a yaw brake control that applies a yaw moment to the vehicle based on the evacuation course.

A driving support controller determines whether it is an opportunity to change a traveling lane based on a predetermined condition in an self-driving activated state in which an acceleration, a deceleration, and a steering of a vehicle equipped with the driving support controller can be automatically controlled, and performs a control to present a lane change proposal to an operator of the vehicle when a lane change is determined to be possible. The device performs an automatic lane change control in response to an intention of the operator agreeing to the lane change proposal. In this case, when the operator's intention is determined to be in disagreement with the lane change proposal, the control to present the lane change proposal to the operator is suspended until a predetermined cancelling condition is met.
