Problems solved by technology

In such a case, the output of the fuel cell is limited in order to lower the temperature of the fuel cell
Here, when the fuel cell vehicle is driving a heavy towed vehicle while driving on a steep uphill route, the fuel cell temperature may become high, limiting the output and reducing the vehicle speed.

Embodiment Construction

[0038] [Schematic structure of fuel cell vehicle 1]

[0039] figure 1 It is a block diagram of the fuel cell vehicle 1 . In the fuel cell vehicle 1, the fuel cell (hereinafter, referred to as FC) 4 is a power source, and the motor 50 is a driving source. The fuel cell vehicle 1 includes an ECU (Electronic Control Unit) 3 , an FC 4 , a secondary battery (hereinafter, referred to as BAT) 8 , an oxidant gas supply system 10 , a fuel gas supply system 20 , a power control system 30 , and a cooling system 40 . In addition, the fuel cell vehicle 1 includes an accelerator opening sensor 6 , an ignition switch 7 , an instrument panel display 9 , a driving motor 50 , a transmission 52 , wheels 55 , and a navigation device 60 . The instrument panel display 9 is provided at a position in the passenger compartment that can be operated by the driver. The navigation device 60 has a touch-panel-type navigation display 61 that can be operated by the driver.

Abstract

Provided are a control device for a fuel cell vehicle and a fuel cell vehicle. The control device for a fuel cell vehicle includes a power limiter limiting power of a fuel cell when a temperature correlation value correlated to a temperature of the fuel cell indicates that the temperature is equal to or higher than a temperature threshold, a calculation unit calculating a weight of a towed vehicle, a gradient acquirer acquiring upward gradients at respective points on a planned traveling route, a predictor predicting whether the power of the fuel cell is limited when the fuel cell vehicle is traveling along the planned traveling route in a towing travel state, and a controller issuing, when the predictor predicts that the power of the fuel cell is limited, an alert that a vehicle speed of the fuel cell vehicle is expected to decrease when the fuel cell vehicle is traveling along the planned traveling route in the towing travel state.

Description

technical field [0001] The present invention relates to a control device of a fuel cell vehicle and a fuel cell vehicle. Background technique [0002] There is a case where the engine vehicle drives the towed vehicle (for example, see Japanese Patent Application Laid-Open No. 2017-007442). [0003] It is conceivable that the fuel cell vehicle drives the towed vehicle similarly to the engine vehicle. Here, when the fuel cell is maintained in a high output state, the temperature of the fuel cell may rise excessively. In such a case, the output of the fuel cell is limited in order to lower the temperature of the fuel cell. Here, when the fuel cell vehicle travels on a route with a steep uphill gradient while towing a towed vehicle with a large weight, the fuel cell may become high temperature, limiting the output, and possibly reducing the vehicle speed. SUMMARY OF THE INVENTION [0004] The present invention provides a control device for a fuel cell vehicle and a fuel cel...
