Vehicle state information is input, and a control amount, which is control state information, is calculated from the vehicle state information to control a controlled device. A control state is monitored by a monitor unit, and an abnormality is detected based on a state where the vehicle state information or the control state information exists in an abnormality region in which the vehicle state information or the control state information has not reached a failure region corresponding to a failure. The vehicle state information, the control state information, and monitor information are stored in a buffer for a period set in advance while always updating the latest vehicle state information, control state information, and monitor information. When the abnormality is detected, the above respective information before and after the abnormality detection including the information stored in the buffer are stored in a nonvolatile storage unit.

An engine ECU executes a control routine including steps of performing output variation control for periodically varying the output of an engine, if control of the engine is not being stopped, at the time of a communication abnormality, and a predetermined time elapses from the time of occurrence of the communication abnormality, and a step of performing fuel-cut control, when the engine speed falls outside a predetermined range.

A vehicle control device include a processor. The processor is configured to monitor a primary power source and a secondary power source for anomalies, the primary power source and the secondary power source supplying electrical power to a plurality of drive devices configured to control deceleration and steering of a vehicle, and in a case in which an anomaly has been detected in at least one of the primary power source or the secondary power source as a result of the monitoring, control the vehicle by supplying electrical power to a drive device having a lower electrical power consumption amount among the plurality of drive devices.

A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing includes a single external power access for the shift actuator. A controller interprets controls the shift actuator with actuating and opposing pulses, and interprets a shaft displacement angle, determines if the transmission is in an imminent zero or zero torque region, and performs a transmission operation in response to the transmission in the imminent zero or zero torque region.

A hydraulic pressure control device of a vehicle driving device, the hydraulic pressure control device includes a range switcher having a first signal solenoid valve capable of supplying a first signal pressure and a spool switchable between a first position reached via the first signal pressure and a second position reached via a biasing force of a biasing member.

A vehicle control apparatus comprises a first travel control unit and a second travel control unit that are configured to perform vehicle travel control by device control. The first travel control unit includes an instruction unit configured to instruct the second travel control unit to execute alternative control, a stop unit configured to stop the device control if execution of the alternative control was instructed by the instruction unit, a reception unit configured to receive information regarding an execution status of the alternative control from the second travel control unit, and a determination unit configured to determine whether the stopping of the device control by the stop unit is to be cancelled, based on the information regarding the execution status of the alternative control that was received by the reception unit.
