Abstract

A control apparatus for a hybrid car is provided, capable of reliably protecting an electric double layer capacitor from being subjected to an excess voltage. A hybrid car comprises an engine E, a clutch 10, driving wheels W, a motor 19, an electric double layer capacitor 21 for supplying electric power to the motor and for storing the electric power generated by the motor, a switching device 23 for connecting or disconnecting the electric double layer capacitor and the motor, and a voltage detecting device 22 for detecting the terminal voltage of the electric double layer capacitor, and a control device 20 for controlling the switching device in response to the terminal voltage detected by said voltage detecting device, wherein when the terminal voltage of the electric double layer capacitor exceeds a standard value, while the motor is actuated as a brake, the control device is constituted such that the connection between the electric double layer capacitor and the motor is disconnected and the clutch is connected.
