A navigation terminal includes a communicator, an alerter, and a processor. The processor obtains destination information indicating a user's destination, obtains first location information indicating the location of the navigation terminal, starts navigation according to a route calculated based on the destination information and the first location information, obtains second location information indicating the location of the navigation terminal after starting the navigation, starts the alerter when the distance from the location indicated by the second location information to a predetermined spot on the route becomes smaller than or equal to the first distance, and causes the communicator to transmit a control signal to a wearable terminal of the user to vibrate a vibrator in the wearable terminal when the distance from the location indicated by the second location information to the predetermined spot becomes smaller than or equal to a second distance smaller than the first distance.

An information processing system includes: an acquisition unit configured to acquires position information indicating a position of a vehicle, sensor performance information indicating the performance of a sensor mounted on the vehicle, and weather information corresponding to the position of the vehicle; and a database creation unit configured to creates correlation data indicating a correlation between the weather information and the sensor performance information on the basis of the information acquired by the acquisition unit.

Navigation method and system are provided. The navigation method may include: a vehicle mounted system, which includes a storage device and a display, receiving a Turn-by-Turn navigation guidance instruction from a mobile device which has a navigation program running thereon; the vehicle mounted system selecting at least one guidance logo, stored in the storage device, according to the received Turn-by-Turn navigation guidance instruction; and the vehicle mounted system presenting on the display the at least one selected guidance logo. More vehicles can provide navigation with help of the mobile device.

A video display system for a vehicle includes a video display device disposed in the vehicle so as to be viewable by a driver of the vehicle. A camera is disposed at the vehicle and having an exterior field of view and operable to capture image data. The field of view of the camera encompasses a blind spot of the vehicle. A control includes a data processor. The control, responsive at least in part to processing by the data processor of data captured by at least one sensor of the vehicle, detects an object present exterior of the vehicle that is in the field of view of the camera. Responsive to detection of the object present exterior of the vehicle, the control controls the video display device to episodically and automatically display video images of the object that are derived from image data captured by the camera.

A navigation method is implemented by a group of portable devices which are associated with a map-and-information system and each of which is communicatively coupled to an instrument cluster device of a respective vehicle. The group of the portable devices includes a leader device and at least one follower device. The map-and-information system computes, for the follower device, a dynamic navigation path from the follower device to the leader device. The instrument cluster device of the vehicle that corresponds to the follower device perceivably outputs the dynamic navigation path.

An event is detected at a first device. Responsive to the detection, at least some functionality of the first device is deactivated. The presence of a second device, cryptographically paired with the first device, is detected by the first device. Responsive to the detection, at least some functionality of the first device is activated or reactivated.

A navigation method includes steps of: repeatedly emitting, by a wheel speed sensor, a pulse signal to a processor of a vehicle when the vehicle starts to travel from a start point of a route of a map; in response to receipt of a preset number of the pulse signals transmitting, by the processor, the preset number of the pulse signals to a portable device; calculating, by the portable device, a current position of the vehicle on the map based on a distance associated with the preset number of the pulse signals; and transmitting, by the portable device, data of the map having the current position to the processor so as to display the same.

A method for assisting a driver of a vehicle in finding a facility providing a service required by the vehicle is proposed. The vehicle includes an instrument cluster device communicatively coupled to a portable device having a navigation function. When an energy level of the vehicle is low, the instrument cluster device triggers the portable device to compute data for a navigation screen that indicates an energy resource supplement facility in a vicinity of the portable device, and to transmit the data to the instrument cluster device, so that the instrument cluster device displays the navigation screen.

Devices and methods in a configurable human machine interface (HMI) for multiple vehicle display devices are disclosed. An example of the method includes, in the HMI control unit for a plurality of vehicular display devices, receiving action input data from a configurable application input module in a first operational mode. In the first operational mode a first vehicular display device operates as a master vehicular display device relative to a second vehicular display device. The second vehicular display device is mirrored to the first vehicular display device. When action input data indicates a transition from the first operational mode to a second operational mode, the method continues by generating a control message based on the action input data. The control message indicates that the second vehicular display device operates as the master vehicular display device and that the first vehicular display device provides mirrored feedback relating to a subsequent action input data affecting a corresponding graphic user element of the second vehicular display device.
