A vehicle lamp provided in a vehicle that travels at a corner by tilting a vehicle body includes: a light source unit; a sensor configured to detect information on outside of the vehicle; and a housing that houses the light source unit and the sensor. The vehicle lamp is disposed at a central portion of the vehicle body in a left-right direction, and wherein the sensor is disposed in the housing at a central portion in the left-right direction.

The objective is to improve driving feeling at a time of acceleration operation or deceleration operation, by recognizing driver's intention of acceleration or deceleration during straight-ahead running. A driving-assistance control apparatus according to the present disclosure includes a straight-running determination unit that determines whether or not a vehicle is running straight, a head-position detection unit that detects a head position of a driver, a driving-posture determination unit that determines the posture of the driver, based on the head position detected by the head-position detection unit, and a driving-assistance control unit that performs acceleration preparation control for raising a reaction speed for acceleration operation or deceleration preparation control for raising a reaction speed for deceleration operation in accordance with an output of the driving-posture determination unit, when the straight-running determination unit determines that a vehicle is running straight.

Various embodiments of transportation devices that have at least two axes of rotation and employ ride balance based drive control are disclosed. One embodiment is a scooter type device with a platform structure movable in fore-aft. The drive motor may be provided at the platform section or drive wheel or be otherwise located. Other embodiments include inline wheeled board embodiments. Yet other embodiments include those utilizing a continuous track. The continuous track embodiments may have two drive motors, among other features.

A self-propelled, one-wheeled vehicle may include a board having two deck portions each having a concave front footpad configured to receive a foot of a rider, and a wheel assembly disposed between the deck portions. The concave front footpad has a rider detection sensor in the form of a membrane switch conforming to the shape of the footpad (e.g., facilitated by one or more slots formed in the membrane switch). A motor assembly drives the vehicle in response to board orientation and rider detection information.

A straddle type vehicle comprises a front antenna configured to be capable of transmitting/receiving a wireless signal of a predetermined frequency band and arranged closer to a front side than a seating portion on which a rider can sit, and a rear antenna configured to be capable of transmitting/receiving a wireless signal of a predetermined frequency band and arranged closer to a rear side than the seating portion, the front antenna has directivity in the front side of the straddle type vehicle.
