Problems solved by technology

[0004] However, when the exhaust gas outlet is arranged behind the rear wheel axle of the vehicle, the liquid water discharged together with the exhaust gas is scattered to the rear of the running vehicle, and there is a problem that the liquid water falls on the rear vehicle.
On the other hand, when the discharge port is arranged between the front wheel shaft and the rear wheel shaft, although it is blocked by the under cover of the vehicle and the splashing of liquid water to the rear of the vehicle can be suppressed, when the vehicle stops, the exhaust gas will be discharged when the vehicle is not running. Easy to stay in the lower part of the bottom cover
In this case, the water vapor in the exhaust gas falls on the rear wheels, and there are cases where the rear wheels become wet

no. 1 approach

[0053] figure 1 , figure 2 It is an explanatory diagram showing a schematic configuration of the vehicle 10 according to the first embodiment. The vehicle 10 includes a fuel cell module 100, an exhaust pipe 110, a muffler 120, an exhaust port 130, a guide 140, an actuator 142, a drive motor 12, a front axle 13, a rear axle 14, a fuel tank 15, a speedometer 16, The bottom cover 17f, 17r, the underfloor part 18, and the control part 20.

[0054] The fuel cell module 100 is installed in a front compartment 11 provided at the front of the vehicle 10 . Here, the "front" of the vehicle 10 is the traveling direction of the vehicle 10 during normal travel, and the "rear" is the reverse direction of the "front". "Right" and "left" of the vehicle 10 are right and left, respectively, when the vehicle 10 is facing the direction of travel during normal travel. "Up" and "down" of the vehicle 10 are up and down in the vertical direction of the vehicle 10, respectively. The output of th...

no. 2 approach

[0075] Figure 10 , Figure 11 It is an explanatory diagram showing a schematic configuration of a vehicle 10 according to the second embodiment. The vehicle 10 according to the second embodiment includes a fan 150 in the underfloor portion 18 . In the present embodiment, fans 150 are provided on the left and right sides of discharge port 130 to form an airflow flowing from the front to the rear of vehicle 10 . Based on the speed v of the vehicle 10 , the control unit 20 drives the fan 150 to rotate when the speed of the vehicle 10 is not more than vth, and stops the fan 150 when the speed is higher than vth. While vehicle 10 is not running, the exhaust gas discharged from exhaust port 130 diffuses in the left and right directions of vehicle 10 . When the exhaust gas reaches the air flow by the fan 150 , the flow velocity of the exhaust gas toward the rear of the vehicle 10 increases due to the flow of the air, and moves toward the rear of the vehicle 10 . On the other han...

no. 3 approach

[0079] Figure 12 , Figure 13 It is an explanatory diagram showing a schematic configuration of a vehicle 10 according to the third embodiment. In the vehicle 10 of the third embodiment, a duct 160 is provided as a guide portion. In the present embodiment, the duct 160 has, for example, a cylindrical shape. The cross-sectional area of ​​the duct 160 is larger than the opening area of ​​the outlet of the discharge port 130 . The inlet of duct 160 covers the outlet of discharge port 130 from vertically above, and reaches the rear of vehicle 10 . The outlet of the duct 160 is provided at the rear of the rear axle 14 of the vehicle 10 . In the present embodiment, the duct 160 is provided above the rear under cover 17r of the vehicle 10 . If the duct 160 is above the rear bottom cover 17r, it is difficult for garbage and dust to enter the duct 160, and the duct 160 is less likely to be clogged. In the present embodiment, duct 160 has a straight shape toward the rear of vehic...

Abstract

The invention provides a fuel cell vehicle and a control method thereof. A fuel cell vehicle comprises a fuel cell module, a discharge port through which exhaust gas including water produced in the fuel cell module is discharged, the discharge port being disposed on an under floor and between a front wheel axle and a rear wheel axle of the fuel cell vehicle, and a guiding section capable of guiding the exhaust gas to flow toward a rearward side beyond the rear wheel axle while the fuel cell vehicle is in a non-running state.

Description

[0001] This application claims priority based on Japanese application No. 2017-113242 filed on June 8, 2017 and Japanese application No. 2017-180766 filed on September 21, 2017, and discloses them The entire content is referred to and quoted for this application. technical field [0002] The present invention relates to a fuel cell vehicle and a control method thereof. Background technique [0003] Japanese Patent Application Laid-Open No. 2015-209043 discloses a fuel cell vehicle in which a fuel cell stack is arranged in front of the vehicle, for example, in a front compartment, and exhaust ports from the fuel cell stack (fuel cell module) are arranged in the rear of the vehicle. [0004] However, when the exhaust gas outlet is arranged behind the rear wheel axle of the vehicle, the liquid water discharged together with the exhaust gas is scattered to the rear of the running vehicle, and there is a problem that the liquid water falls on the rear vehicle. On the other hand,...
