Patent Images
1. A regenerative braking control system for an electric vehicle, comprising:
- an electric energy supply source mounted on said vehicle;
an electric motor electrically connected to said electric energy supply source and having a power output shaft connected to a driving wheel of said vehicle;
a driving state detection unit including an inclination detecting unit for detecting an inclination of said vehicle in running; and
a control unit for controlling regenerative braking force of said electric motor on a basis of detection information from said inclination detecting unit of said driving state detection unit wherein said control unit is provided with a storage unit for determining the regenerative braking force of said electric motor at least in accordance with said detection information from said inclination detecting unit, and said control unit obtains, from said storage unit, a signal indicative of said regeneration braking force that corresponds to said detection information, and controls the regenerative braking based on said obtained signal.

Abstract
A regenerative braking control system for an electric vehicle which can be driven by operating an electric motor with electric energy supplied from an electric energy supply source mounted on the vehicle. A control unit (7) is designed so that regenerative braking force of the electric motor (2) is controlled in accordance with an inclination detected by an inclination detecting unit (28). This has made it possible to provide the electric vehicle with improved drivability and running performance.
