VEHICLE CONTROLLER AND CONTROL METHOD
First Claim
1. A controller for a vehicle including a power storage mechanism, a converter boosting electric power from said power storage mechanism, and a rotating electric machine that operates with the electric power from said converter, comprising:
- a detecting unit for detecting which operation mode of a normal mode and an economy mode is selected by a driver of said vehicle; and
a control unit;
whereinsaid control unit limits boosting by said converter and limits output torque of said rotating electric machine, when selection of said economy mode is detected by said detecting unit, calculates a required torque value of said rotating electric machine, and based on said required torque value, cancels at least one of said limit on boosting and said limit on the output torque.

Abstract
By the vehicle controller of the present invention, when the economy mode is selected by a driver, boosting by a converter is limited and output torque of a motor is limited. Even in the economy mode, however, if the driver requests large torque, either the limit on boosting or the limit on output torque is cancelled. As a result, a vehicle controller for a vehicle including a battery, a converter boosting/lowering the battery voltage and a motor operating with the power from the converter is provided, by which unnecessary power consumption is reduced and the torque requested by the driver can be generated.
