A driving assistance apparatus including a display part, a distance measurement part measuring inter-vehicle distance from a subject vehicle to a preceding vehicle and a microprocessor. The microprocessor is configured to perform acquiring traffic light information including switching information on a traffic light and position information on the subject vehicle with respect to the traffic light, deriving a recommended driving for the driver based on the traffic light information and the position information, and controlling the display part so as to notify the driver of information on the recommended driving, the controlling including controls the display part so as to display a first image corresponding to the recommended driving when the inter-vehicle distance is larger than a predetermined value and to display a second image as warning information together with the first image when the inter-vehicle distance is equal to or smaller than the predetermined value.

Driving assistance apparatus

An information transmission system including a first vehicle and a second vehicle, the first vehicle being subjected to a traffic control by a traffic light, the second vehicle being subjected to the traffic control by the traffic light after the first vehicle, each of the first vehicle and the second vehicle including a communication unit capable of communicating with each other, and an electronic control unit including a microprocessor and a memory connected to the microprocessor. Each of the microprocessor of the first vehicle and the microprocessor of the second vehicle is configured to perform acquiring a change information of the traffic light, and updating the change information acquired, and the microprocessor of the second vehicle is configured to perform the acquiring including acquiring the change information updated by the microprocessor of the first vehicle through the communication unit.

Information transmission system

A traffic system including a first vehicle and a second vehicle. The first vehicle includes a communication unit, a detection device detecting an external situation around the first vehicle, and a microprocessor configured to perform recognizing a moving object based on the external situation detected, determining whether there is an approach risk indicating that a distance from the second vehicle to the moving object becomes equal to or shorter than a predetermined value, and outputting an approach signal when it is determined that there is the approach risk. The second vehicle includes a communication unit, a warning unit issuing an alarm outside of the second vehicle, and a microprocessor configured to perform controlling the warning unit so as to issue the alarm when the approach signal output from the first vehicle is received through the communication unit.
