A driving assistance apparatus according to the present disclosure includes: a vehicle acceleration detection unit configured to detect vehicle acceleration including lateral acceleration and longitudinal acceleration of a vehicle; a calculation unit configured to calculate for each wheel a friction circle, and a lateral force generated at each wheel and a longitudinal force generated at each wheel on the basis of a result of detection by the vehicle acceleration detection unit; and a display unit configured to display an image based on the friction circle, and a magnitude and/or a direction of a resultant force of the lateral force and the longitudinal force generated at each wheel based on a result of calculation by the calculation unit.

Driving assistance apparatus, recording medium having driving assistance program recorded thereon, and driving assistance method

A map generating server capable of bidirectional communication with multiple vehicles having a database configured to store vehicle type identifiers assigned to the vehicles and map data regarding roads usable by the vehicles and cultivated land area near the roads. In the server, a vehicle position data tagged with vehicle type identifier is successively written to location concerned of the map data when each vehicle transmits the position data tagged with the vehicle type identifier. The vehicle position data writing number is incremented if the written vehicle position data is that of a vehicle assigned a specified vehicle type identifier, and the location concerned of the cultivated land area is determined to be cultivated land area road and to update the map data stored in the database when the writing number is equal to or greater than a predetermined number.
