摘要： An electric vehicle driven by a motor is provided with a secondary battery and a generator which are controlled by a controller so that when an amount of charge of the secondary battery becomes lower than a predetermined value of the generator is put from a stopping state into an operating state and so that when the amount of charge of the secondary battery becomes higher than another predetermined value the generator is put from the operating state into the stopping state. The controller changes the predetermined values in accordance with the changing rate of the electric energy consumption of the secondary battery so that the secondary battery loses it amount of charge after the generator becomes empty of its fuel. The electric vehicle can fully perform its characteristic and the generator is effectively operated by storing excessive electric energy of the generator and effectively using the secondary battery.

摘要： A vehicular power steering system is provided with a steering effort control system which controls the degree of power assistance by controlling the supply of hydraulic fluid to the hydraulic power actuator unit. The steering effort control system monitors the speed of the vehicle and the angular velocity of the steering wheel, and controls the quantity of the fluid supply in accordance with the monitored variables. The fluid supply quantity is determined so as to satisfy the following three conditions: (1) The steering must become heavier as the vehicle speed increases; (2) however, a sufficient amount of the fluid must be supplied even when the steering wheel is turned rapidly; and (3) the driver must be given a feel about the lateral acceleration of the vehicle during a turn.

摘要： In a vehicular power steering system, the hydraulic fluid supply to a hydraulic power actuator is controlled in accordance with the vehicle speed and the angular velocity of the steering wheel. Preferably, the fluid supply is reduced so that the steering effort becomes heavier as the vehicle speed increases while the fluid supply is increased when the angular velocity of the steering wheel is high. To control the fluid supply, there is provided, in a power steering system, a bypass valve means for draining a portion of the fluid flow to bypass the power actuator, and control means for producing a control signal to control the bypass valve means in accordance with the vehicle speed and the angular velocity of the steering wheel.
