Abstract: An ECU causes an injector to implement multiple split injections during a combustion cycle and to implement a final split injection among the split injections in the latter half of the compression stroke. The ECU further sets a time interval between the injection timing for the final split injection and the ignition timing of an ignition plug at a constant time in a region in which the fuel pressure is the same. Then, the ECU sets a crank angle position based on the time interval and a rotational speed of an output shaft.

Abstract: A parking assist device performs parking assist. A vehicle receives assist from the parking assist device. A type determination unit determines a type of received data, which represents data received from the parking assist device or the vehicle. A replacement transmission unit replaces the received data with at least one transmission data, which is prepared in advance, according to the type of the received data and transmits the transmission data to the receiver device, when the type of the received data is a first type. A transfer unit transfers the received data as the transmission data to the receiver device when the type of the received data is a preset second type.
