Abstract
Abstract A motor vehicle including a vehicle body, a front road wheel disposed in the front part of the vehicle body, a rear road wheel disposed in the rear part of the vehicle body, an engine for driving at least either of the front and rear road wheels, and a steering wheel for steering at least either of the front and rear road wheels. To facilitate the steering operation, the motor vehicle is improved by means of a transverse sliding angle detection system for detecting the transverse sliding angle of the vehicle body, and a moving direction display unit for visually displaying the moving direction of the vehicle body on the basis of an output of the transverse sliding angle detection system.
