A route retrieval apparatus includes a route retrieval unit configured to perform route retrieval from a departure place to a destination, the route retrieval retrieving a route using one or two or more pieces of moving means among a plurality of pieces of moving means including sharing type moving means in which a vehicle with a relatively small riding capacity is used by unspecified people, and perform the route retrieval from the departure place to the destination, the route retrieval retrieving a route including usage of the sharing type moving means, such that the usage of the sharing type moving means is restricted to at least one of usage from the departure place or a periphery of the departure place and usage for reaching the destination or a periphery of the destination.

Processing circuitry of an in-vehicle cooling system regulates the flow rate of the coolant passing through a radiator, thereby regulating the coolant temperature to a target coolant temperature. The processing circuitry sets the target coolant temperature to a specified standard target coolant temperature when the engine is not operating in a specified temperature increase permitting range, and sets the target coolant temperature to a high target coolant temperature, which is higher than the standard target coolant temperature, when the engine is operating in the temperature increase permitting range. The processing circuitry changes the target coolant temperature in the temperature increase permitting range to a temperature lower than the high target coolant temperature and higher than or equal to the standard target coolant temperature, when the hydraulic oil temperature is higher than or equal to a specified temperature increase suppressing temperature.

In-vehicle cooling system and method for controlling the same

An engine cooling device has a mechanical water pump, a flow rate control valve having a valve body of which a relative rotational position is changed by a motor, and a control unit that performs drive control of the motor to change the relative rotational position of the valve body to a target relative rotational position. The control unit performs protection control for setting the relative rotational position where a withstanding pressure limit rotational speed is equal to or higher than a current engine rotational speed, as a target operating position of the valve body of the flow rate control valve when the engine rotational speed rises, and performs retreat control for reducing a set range of the target relative rotational position to a prescribed retreat operation range when the supply voltage of the in-vehicle electric power supply has dropped.
