Regenerative braking control system for electric vehicle

A brake apparatus for an electric automobile applies brakes to the vehicle to achieve a required amount of braking force by combining regenerative braking force of an electric motor with mechanical braking force produced by a mechanical braking system. The braking force required by a driver is obtained from the depression force applied to a brake pedal, and the maximum regenerative braking force, that can be generated by the motor, is obtained from the rotation speed of the motor. The target mechanical braking force is calculated based on the required braking force and the maximum regenerative braking force. By suitably controlling the pneumatic pressure applied to a booster device provided in the mechanical brake system, the fluid pressure actually applied to brake actuating members is controlled to provide the target mechanical braking force.

Brake apparatus for electric automobile utilizing regenerative braking

A navigation system suitable for use in an electric automobile, especially hybrid electric automobiles, easily and properly controls charging state of a battery in the electric automobile while making use of characteristic features of the navigation system. The navigation system is mounted on the electric automobile. A destination, to which one wants to drive by the automobile, is inputted as drive plan information. Based on a distance planned to be driven by the automobile to the destination and a remaining capacity of the battery determined by remaining capacity detector, it is determined whether the automobile can reach the destination with the remaining capacity of the battery.
