electric vehicle after Claim 4 , in which, in the electric vehicle, the backrest of the first seat is positioned above the wheel arch.
electric vehicle after Claim 6 , wherein, if assisted driving by the driving assistant is required instead of the automatic driving function, the display unit changes the optical information to indicate that assisted driving is to be carried out and displays the changed optical information.
An electric vehicle with a wheel hub motor mounted on a front wheel and a rear wheel, and comprising an automatic driving function, the electric vehicle comprising: a first seat arranged to overlap, in plan view from a roof-facing side of the electric vehicle, a wheel center axis connecting the pivot axes of a left rear wheel and a right rear wheel mounted to the wheel hub motor; a second seat arranged along a side surface of the electric vehicle in the direction of travel of the electric vehicle; a third seat arranged at an intersection of the first and second seats; and a passenger access door arranged along the other side surface of the electric vehicle facing the second seat.

Description

Technical field The present invention relates to an electric vehicle with one seat and in particular to an electric vehicle with an automatic driving function. State of the art In a conventional electric vehicle, such as an electric passenger car steered by a steering wheel, the drive system and seating are arranged to be as symmetrically left-right as possible, in order to position the vehicle's center of gravity in a left-right direction when viewed from the front. This is because the existing drive system can independently control and drive the front and rear wheels, but cannot independently control and drive the left and right wheels, and this configuration is essential for ensuring left-right vehicle balance. An example of symmetrically arranged left-right seats is, for instance, a... JP 11-321465 A (PTL 1) seating arrangement is known. List of citations Patent literature PTL 1: JP 11-321465 A Summary of the invention Technical task However, the seating arrangement of the conventional passenger vehicle described in PTL 1 has a cramped spatial feel, and the seating arrangement cannot necessarily be described as a comfortable interior, especially on a long journey. However, in an electric vehicle with an automatic driving function, since there is no steering wheel, it is possible to assume a seating arrangement where the direction of the front seat is reversed by 180° in the front-to-back direction, and this is expected to ensure a wide interior. However, even in this case, it is difficult to say that the feeling of confinement is significantly improved, since the front and rear seats are arranged symmetrically left-to-right, taking into account the vehicle's center of gravity. Furthermore, the left and right wheels on the front side and the left and right wheels on the rear side are each connected by drive shafts. Because of this, the presence of the drive shaft makes it difficult to move the front seat forward or backward while the vehicle's floor is raised and the vehicle's height is maintained. From this perspective, it's difficult to say that the cramped conditions have been improved. Therefore, there is a need for an electric vehicle with an automatic driving function capable of ensuring a spacious and comfortable interior. One object of the present invention is to provide an electric vehicle with an automatic driving function that is capable of ensuring a wide and comfortable interior space. Solution to the task To achieve the above objective, the present invention comprises various embodiments, and as an example, an electric vehicle of the present invention is an electric vehicle with a wheel hub motor mounted on a front wheel and/or a rear wheel and having an automatic driving function, wherein the electric vehicle comprises a first seat, arranged to overlap with a wheel center axis connecting the axes of rotation of a left wheel and a right wheel mounted with the wheel hub motor, as seen from a top view from a roof side (top) of the electric vehicle, a second seat arranged along a direction of travel of the electric vehicle, and a third seat arranged at an intersection of the first seat and the second seat, and the seats are arranged asymmetrically left-right in a top view, wherein a vehicle center axis in the direction of travel of the vehicle serves as a boundary. Furthermore, the present invention is an electric vehicle with a wheel hub motor mounted on a front wheel and a rear wheel and having an automatic driving function, wherein the electric vehicle comprises a first seat, arranged to connect with a wheel center axis the axes of rotation of a left rear wheel and a right rear wheel mounted with the wheel hub motor, as seen from a top view from a roof side of the electric vehicle; a second seat, arranged along a side surface of the electric vehicle in the direction of travel of the electric vehicle; a third seat, arranged at an intersection of the first seat and the second seat; and a passenger access door, arranged along the other side surface of the The electric vehicle is arranged in a way that faces the second seat. Advantageous effects of the invention According to the present invention, it is possible to provide an electric vehicle with an automatic driving function capable of ensuring a spacious and comfortable interior.
