A control device for an internal combustion engine is applied to an internal combustion engine mounted on vehicles in which filters for collecting PM are arranged in an exhaust passage. After the internal combustion engine is started, the control device of the internal combustion engine executes a temperature raising process of raising the upstream side exhaust temperature, which is the temperature of the exhaust gas on the upstream side of the filter in the exhaust passage, until the condensed water of the filter reaches a vaporized state.

Control device for internal combustion engine

A control device starts supply of electric power to a catalyst device when a state of charge of a main battery decreases to a value which is equal to or less than an optimal power-supply state of charge set based on a travel load while a vehicle is traveling in an EV travel mode. The control device corrects input electric power of the catalyst device to a value less than the value at the time of starting of supply of electric power when the travel load decreases after the supply of electric power has been started.

Control device for hybrid vehicle

A navigation server includes a processor. The processor is configured to derive one of a first route and a second route as a route from a place of departure to a destination of a vehicle in accordance with a remaining level of a travel battery of the vehicle. The first route includes a first road provided with a first non-contact electric power feeder. The second route includes a second road provided with a second non-contact electric power feeder that is different in electric power feed capability from the first non-contact electric power feeder. The processor is configured to output the derived route as a recommended route to a terminal associated with the vehicle.

Navigation server, non-transitory storage medium, and navigation system

A control device is applied to an internal combustion engine equipped with an electric heating catalyst system provided with an EHC. The control device executes a preheating process to warm up an exhaust gas reduction catalyst prior to a start of the internal combustion engine by supplying electric power to the EHC, when the control device determines that a temperature of the exhaust gas reduction catalyst is lower than an activation temperature. The control device executes a determination process for determining whether water is adhered to a catalyst carrier. The control device starts the internal combustion engine without executing the preheating process when the control device determines by the determination process that water is adhered to the catalyst carrier, even when the control device determines that the temperature of the exhaust gas reduction catalyst is lower than the activation temperature.

A controller is applied to an internal combustion engine in which an electrically heated catalyst that is heated when supplied with electric power is installed in an exhaust passage. The controller is configured to perform a preheating process of warming up a first exhaust catalyst by supplying electric power to the electrically heated catalyst through control over a power supply before a start of the internal combustion engine. The controller is configured to, when an insulation resistance of the electrically heated catalyst at a start of the preheating process is lower than a threshold, perform the preheating process while decreasing a voltage supplied to the electrically heated catalyst.
