First Claim
Patent Images
1. A control device for a solar cell mounted in a vehicle, the control device comprising:
- an electronic control unit (ECU) configured to;
determine whether the vehicle is in a travelling state or a stationary state;
detect a speed of the vehicle when the vehicle is in the travelling state; and
set a control cycle of a maximum power point tracking (MPPT) control for the solar cell based on the speed of the vehicle,wherein the ECU is configured to, in the travelling state, perform the MPPT control for the solar cell when the speed of the vehicle is less than a predetermined speed, andwherein the ECU is configured to, in the travelling state, suspend the MPPT control and perform a fixed voltage control for the solar cell when the speed of the vehicle is equal to or more than the predetermined speed.
