Drive-and-control system for hybrid vehicles
First Claim
1. A drive-and-control system for mounting in a hybrid vehicle, the hybrid vehicle operated using an engine and a motor as power sources, the drive-and-control system driving and controlling the engine and the motor so that an amount of charge in a battery will approach a control index during a running from a point of departure to a target point, the drive-and-control system comprising:
- a running information storage means for storing running information used to determine the control index in a memory while the vehicle is run; and
a control index storage control means for planning a schedule of control indexes in association with a predetermined zone, the schedule of the control indexes planned on the basis of the running information stored in the memory, when a decision was made that the vehicle had reached a target point, so that the fuel consumption of the engine for the route from the point of departure to the target point will be reduced, and stores the schedule of the control indexes in the memory.

Abstract
A schedule of control indexes can be planned for a route providing high accuracy control of an engine, a motor and a battery in a hybrid vehicle. Running information used to determine control indexes is collected while a vehicle is run from a point of departure to a destination and stored in a storage medium. When the vehicle has reached a destination, a schedule of control indexes is planned on the basis of the stored running information. Control of the hybrid vehicle using the plan reduces fuel consumption of an engine from the point of departure to the destination.

11. A drive-and-control system for a hybrid vehicle capable of being operated using an engine and a motor as a motive power source, the drive-and-control system driving and controlling the engine and the motor so that an actual state of charge in a battery will approach a control index during a movement of the hybrid vehicle from a point of departure to a target point, a route from the point of departure to the target point divided into a plurality of predetermined zones, the control index representing a reference charge, the drive-and-control system comprising:
-
a memory; a first control unit coupled to the memory, the first control unit configured to; generate and store information in the memory, the information including running information associated with the movement from the point of departure to the target in each of the plurality of predetermined zones; and establish control plan on the basis of the running information, the control plan established when the target point is reached, control plan for providing control of the engine and the motor so as to reduce a fuel consumption of the engine for the route, the control plan stored in the memory; and a second control unit coupled to the memory and the first control unit, the second control unit configured to control the hybrid vehicle according to the control plan. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
