A vehicle controller is provided. A first passage of a supply passage of a blow-by gas processing device is connected to a portion of an intake passage located downstream of a compressor of a forced-induction device. The first passage includes a connection portion connected to the intake passage. A portion of the first passage between the connection portion and a PCV valve is a passage downstream portion. A supercooling determination process determines whether the supply passage is supercooled by relative wind of a vehicle based on a travel speed of the vehicle. An operating state changing process sets operation of the internal combustion engine to non-boosting operation when an ambient temperature of the vehicle is less than or equal to a determination temperature, the PCV valve is determined as being closed, and the supply passage is determined as being supercooled.

Vehicle controller, vehicle control method, and memory medium

An on-vehicle information processing apparatus for implementing various functions in cooperation with a portable apparatus connected thereto in a cabin of a vehicle is disclosed. The on-vehicle information processing apparatus comprises: a communication device configured to communicate with the portable apparatus; and a screen generating device configured to generate an operation screen for the functions which can be implemented in cooperation with the portable apparatus. The screen generating device is configured to identify the functions which can be implemented in cooperation with the portable apparatus connected thereto via the communication device, based on information of the connected portable apparatus, and generate the operation screen which varies according to the identified available function or functions.

On-vehicle information processing apparatus and method

A vehicle-mounted communication device and a road-to-vehicle communication device are provided which each allow communication of information using a simple structure by making leakage of information difficult. Information including encryption information is communicated between an on-road apparatushaving a memoryin which an electronic key A is stored, and a vehicle-mounted apparatushaving a storage circuit. Encrypted route information and the like are stored as is in the vehicle-mounted apparatus. Encryption and decoding are executed at an on-road apparatus side. In reception of charges, encrypted information from an IC cardhaving a memoryin which a security mechanism is stored passes through the vehicle-mounted apparatus and is transferred to the on-road apparatus. The encrypted information from the IC cardis decoded with the on-road apparatus. Accordingly, the encrypted information is mutually transferred between these apparatuses and the vehicle-mounted apparatus does not require encryption or decoding. As a result, the security of a system can be improved.
