摘要： When an ignition switch is turned off, a hydrogen supply valve is closed. Operation of a compressor continues, and an air supply valve and an air discharge valve are opened to supply the compressed air into a fuel cell through a hydrogen supply port. The scavenging process of removing the fuel gas and the water remaining in the fuel gas channel is performed through the air discharge valve, a drain valve, and a hydrogen purge valve. Then, all the valves connected to the fuel gas channel are closed. The pressure when the valves are closed, and the pressure when a short time has elapsed after closing the valves are detected by a pressure sensor. Based on the pressure difference, a failure due to the leakage in the fuel gas channel is detected.

摘要： A control system for an electric vehicle includes an accelerator opening detecting device for detecting a position of an accelerator, and an output command value calculating device connected to the accelerator opening detecting device for calculating an output command value of a drive motor of the electric vehicle based upon the detected accelerator opening. A motor control device is connected to the output command value calculating device, and controls the output of the motor based upon the output command value. An accelerator opening learning device learns actual accelerator opening positions, and includes at least one of a full-closure learning apparatus for generating a full-closure determined value of the accelerator based upon an output of the accelerator opening detecting device, and a full-open learning apparatus for generating a full-open determined value based upon the detected accelerator opening. The system also includes an output command value limiting device for limiting the output command value output by the output command value calculating device until the accelerator opening learning device has generated the full-closure determined value and the full-open determined value. This configuration reduces the rough and unstable output changes of a motor until the learning has been completed.

摘要： The present invention intends to provide a control device for a fuel cell vehicle which suppresses the deterioration of driveability upon acceleration without increasing the size of a driving electric motor or a motor driver. When a requested output (PD_CAL) exceeds a first output limit determined depending on a continuous output rating of an electric motor 10 or a motor driver 5 and an increasing rate of the requested output (PD_CAL) exceeds a reference increasing rate, an upper-limit target output determining unit 52 determines an assist time used as a time during which the electric motor 10 can be operated continuously by the requested output (PD_CAL) on the basis of the requested output (PD_CAL) and an open-circuit voltage (Vbat_o) of a battery 3. Until the assist time is elapsed, the upper-limit target output (PD_LMT) is set to a second output limit (>the first output limit) determined depending on a short-time output rating of the electric motor 10 or the motor driver 5.
