Electric car controller and control method
The electric car controller is characterized in that evaluation two-phase/three-phase converting means (15) for calculating a three-phase evaluation current indication value is provided in control means, and current detected value from current detecting means (8) and evaluation current indication value are compared with each other by a deviation computing means (17). This result is evaluated by error evaluation means (18), and is sent to target command computing means (10), whereby the operation of a drive apparatus is stopped or continued.
