A method for safety improvement during operation of a motor vehicle (100) includes the steps of: determining a prevailing speed of the vehicle (100); automatically activating a warning flasher function (275) on the basis of determined values pertaining to at least some combination of conditions based on: vehicle speed (V) and gradient (L) of the running surface on which the vehicle (100) is travelling, and the speed of the vehicle (100) compared with surrounding traffic and the gradient (L) of the running surface on which the vehicle (100) is travelling. Also a computer program product including program code (P) for a computer (200; 210) for implementing the method is disclosed. Also a system for safety improvement during operation of a motor vehicle (100) and to a motor vehicle (100) which is equipped with the system are disclosed.

An autonomous vehicle includes a vehicle body and an illuminated stripe assembly mounted to the vehicle body. The illuminated stripe assembly is adapted to emit a plurality of stripe patterns that are visually distinctive from one another for indicating different operating states of the autonomous vehicle.

Provided is a light projection system that can be used to indicate a robot's path of travel, a robot including the light projection system, and methods for projecting light to indicate a robot's path of travel. The light projection system can by mounted to the body of the robot, and can be configured to project light onto the ground in front of the robot. The light projection system can be configured to project different illumination patterns that can indicate whether the robot is moving forward, turning, accelerating, and/or slowing down, among other examples.

This disclosure relates generally to motor vehicles, and more particularly to motor vehicle and device for visually indicating a speed of the motor vehicle, and method thereof. In one embodiment, a method is provided for visually indicating a speed of a motor vehicle. The method includes receiving an instantaneous speed of the motor vehicle from one or more odometry devices of the motor vehicle and an instantaneous temperature on an external surface of the motor vehicle from one or more temperature sensors. The method further includes configuring one or more thermoelectric couple strips to regulate temperatures of one or more corresponding thermochromic paint coating layers disposed on the external surface of the motor vehicle, based on the instantaneous speed and the instantaneous temperature, to dynamically control indication of a color pattern associated with a range of instantaneous speed of the motor vehicle.

An illuminated badge system is provided for a motor vehicle. The illuminated badge system includes an illuminated badge and a controller. The controller is configured to adjust a parameter of the light emitted from the illuminated badge in response to a designated operating parameter such as the headlight status of the motor vehicle.

A visual deceleration indicator signals to pedestrians and other vehicles that a vehicle is slowing down or coming to a stop. Illuminating devices, such as LEDs, contained in a license plate frame located in the front of the car or otherwise, are activated when the vehicle decelerates. An accelerometer or other sensory device detects deceleration and sends a signal to illuminate the LEDs, thereby letting others know the vehicle is slowing down. The license plate frame may be connected directly to a rear brake light component without the use of accelerometers or other sensors. When the brake is applied, the LEDs in the license plate frame are illuminated. The LEDs may be contained in other forms and located in different positions on the front or side of the car. The indicator might be one color to indicate braking and another color to indicate it is on, but not braking.

A school-travel assistance system includes automobiles. The automobiles include communication modules configured to communicate with each other, and are configured to perform auto-driving. At least one of the automobiles includes a camera configured to detect the group of children. The automobiles perform assistance control (first and second assistance controls) in which they cooperatively assist movement of the group of children, while communicating with each other through the communication modules. The assistance control is control of assisting the movement of the group of children by the automobile traveling in front of the group of children and the automobile traveling behind the group of children.
