Vehicle and control device

A control device mountable on a vehicle, the vehicle being provided with at least a first wheel and a second wheel so as to be movable by rotating the first wheel and the second wheel, the vehicle comprising a battery, a first power supply cord connected to a positive electrode and a negative electrode of the battery, and a second power supply cord connected to the positive electrode and the negative electrode of the battery, the control device comprising:

• a first circuit;
• a second circuit;
• and
• a housing in which the first circuit and the second circuit are stored,
• wherein the first power supply cord is set to connect at least the positive electrode and the negative electrode of the battery to a first power supply portion and a first ground portion of the first circuit, respectively,
• wherein the second power supply cord is set to connect at least the positive electrode and the negative electrode of the battery to a second power supply portion and a second ground portion of the second circuit, respectively,
• wherein a second consumption current of the second circuit is possible to be larger than a first consumption current of the first circuit,
• wherein the first circuit comprises a control circuit,
• wherein the control circuit is configured to measure a voltage of the second power supply portion of the second circuit as a first voltage with reference to a potential of the first ground portion,
• wherein the control circuit is configured to measure a voltage of the second power supply portion of the second circuit as a second voltage with reference to a potential of the second ground portion, and
• wherein in a case in which the first voltage and the second voltage have a predetermined relationship, power supplied from the second power supply cord to the second circuit is set to be a predetermined value or less.
