摘要： In a fuel cell system of the invention, a hydrogen leakage detection process closes a shutoff valve, which shuts off a supply of hydrogen from a hydrogen supply unit into a hydrogen supply flow path, and opens a pressure regulator, which reduces a pressure of hydrogen in the hydrogen supply flow path, so as to keep the hydrogen supply flow path in a state with no pressure regulation and make the fuel cell system in a leakage detectable state. In this leakage detectable state, the hydrogen leakage detection process measures at least one of a pressure and a flow rate as a state quantity of hydrogen in the hydrogen supply flow path that feeds the supply of hydrogen to fuel cells. The hydrogen leakage detection process analyzes a detected behavior of the state quantity in the leakage detectable process and specifies the occurrence of a hydrogen leakage in the downstream of the hydrogen supply unit. This arrangement enables highly accurate detection of a hydrogen leakage in the fuel cell system with the pressure regulator provided in the hydrogen supply flow path.

摘要： PROBLEM TO BE SOLVED: To carry out adequate movement control before the running condition of a vehicle enters a limit running area, as well as to carry out smooth movement control. SOLUTION: A car body slip angle β and its variation rate βd are operated (S100), an object car body slip angle βref and an object yaw rate γrefg after a guard processing are operated (S150), an object yaw moment YMhp, an object longitudinal force Fxt, and an object lateral force Fyt after a high-pass filter processing are operated (S200), object braking pressures Pwti of the wheels in order to accomplish the YNhp, Fxt, and Fyt are operated (S350), and the braking pressures of the wheels are controlled to make the braking pressure Pwi to an object braking pressure Pwti (S400). The object yaw moment YM before the high-pass filter processing is operated as the weight sum of the first object yaw moment Myr depending on a yaw rate deformation, and the second object yaw moment Msa depending on the car body slip angle, and the weight coefficient is set variable to make a weight coefficient Kt the smaller, as a limit condition evaluation amount A is made the larger.
