Provided is a control system, including: a power source control unit for controlling a power source included in a mobile object; a mobile object control unit for controlling the mobile object; and an update control unit for receiving an update program of the power source control unit and the mobile object control unit, and transmitting the update program to one of the power source control unit and the mobile object control unit to be updated by the update program, wherein the power source control unit includes a first storage area to be updated and a second storage area not to be updated by the update program, and the power source control unit includes, in the second storage area, first control information for causing the power source to supply power in a case where the first storage area is updated by the update program transmitted from the update control unit.

Control system, mobile object, computer-readable storage medium, and control method

Provided is a communication system including: a first communication bus available for communication of at least a first communication scheme; a second communication bus available for both communication of the first communication scheme and communication of a second communication scheme having a lower processing load than the first communication scheme; a plurality of first communication devices connected to both the first communication bus and the second communication bus; a plurality of second communication devices, connected to the second communication bus, which perform communication through the second communication scheme using the second communication bus; and a processor that detects an abnormality of the first communication bus, wherein each of the plurality of first communication devices performs communication through the first communication scheme using the first communication bus in a case where the abnormality of the first communication bus is not detected by the processor, and performs communication through the first communication scheme using the second communication bus in a case where the abnormality of the first communication bus is detected by the processor.

Communication system and communication control method

Provided is a gas sensor that needs no temperature sensor for detecting a temperature of a heater for preventing dew condensation. The gas sensor comprises a hydrogen sensorincluding: an element housinghaving a detection chamberto which hydrogen is introduced; a detection elementarranged in the detection chamberand detecting hydrogen; a heaterfor heating the detection chamberby heat generation via passing an electric current through the heater, a resistance value of the heaterbeing changed corresponding to a temperature of the detection chamber; and a microcomputerand a heater operation circuitfor controlling the heater. Herein, the microcomputercontrols a temperature of the detection chamberby adjusting the electric current passing through the heaterbased on the resistance value of the heater

Gas sensor

A hydrogen detection system can include an exposed detection element made of a catalytic metal which burns hydrogen so as to generate combustion heat. A hydrogen sensor can detect a hydrogen concentration based on a detected value of the detection element. A heating unit can heat the detection element. A hydrogen storage unit is included, and a hydrogen guiding pipe can guide the hydrogen from the hydrogen storage unit to the detection element. A flow rate adjusting device is attached to the hydrogen guiding pipe, and adjusts a flow rate of the hydrogen. A first dilution unit can dilute the hydrogen from the hydrogen storage unit with a dilution gas, and a controller can control the heating unit and the flow rate adjusting device.

Hydrogen detection system

A simple gas sensor for detecting a concentration of a detected gas with high accuracy, in which a thermal interference can hardly occur between a normal detection element pair and a reference detection element pair, is provided.

The gas sensor includes: a cylindrical member which includes a gas detection chamber therein and extends along an axial thereof; a base member which closes an opening of a first axial end of the cylindrical member; a status sensor which is disposed at a substantially central portion of the base member, and detects at least the temperature or the humidity in the gas detection chamber; a gas detection element disposed around the status sensor on the base member; a lid member which closes an opening of a second axial end of the cylindrical member; and a gas inlet port which penetrates the lid member at a location not coinciding with the status sensor and the gas detection element when seen from the axial direction, and enables the introduction of an inspection target gas from an outside into the gas detection chamber.
