The objective is to improve driving feeling at a time of acceleration operation or deceleration operation, by recognizing driver's intention of acceleration or deceleration during straight-ahead running. A driving-assistance control apparatus according to the present disclosure includes

Driving-assistance control apparatus

The posture of the driver is detected from the driver head portion, and the detected value and the driver mounting determination value are used to determine that the driver is pushing the vehicle and obtain the vehicle pushing command value. Converts the vehicle pushing command value to the target vehicle pushing assistance vesicle speed, determines whether vehicle pushing assistance can be performed based on the driver's posture and the vehicle condition, and outputs the vehicle pushing assistance permission determination. Then, from the target vehicle pushing assistance vehicle speed and the vehicle pushing assistance permission determination, the control amount for the vehicle power source that assists the vehicle pushing is calculated and output.

Driving support device

Provided are a driver posture measurement device and a vehicle control device that can accurately measure the posture of a driver with a simple configuration without attaching a plurality of wireless communication units to a vehicle. The driver posture measurement device and the vehicle control device are configured such that, between one wireless communication unit provided on the vehicle side and one wireless communication unit provided on the driver side, radio waves are radiated from the wireless communication unit provided on the vehicle side, and on the basis of a radio wave arrival angle of the radio waves arriving at the wireless communication unit provided on the driver side, the driver posture is measured.

Driver posture measurement device and vehicle control device

The control device for an internal combustion engine disclosed in the present application is a control device that determines the presence or absence of misfire based on an angle detection cycle calculated from an output signal of an angle sensor, the control device includes an arithmetic processing device and a storage device, the control device is configured so that the storage device stores the angle detection cycle calculated in a misfire detection threshold value comparison section after the reference angle section as a threshold value comparison target cycle and is configured such that the arithmetic processing device determines the presence or absence of misfire based on the misfire detection threshold value cycle calculated based on the reference detection cycle and the threshold value comparison target cycle, thereby it becomes possible to accurately determine the presence or absence of misfire in the control device for the internal combustion engine.

Control device for an internal combustion engine

To provide a controller for an internal combustion engine which can determine presence or absence of misfire with good accuracy, even when the rotational variation occurs due to factors other than misfire. A controller for an internal combustion engine calculates, as a reference detection period, the detection period detected within a reference angle interval including a top dead center; calculates a period deviation which is a deviation between the reference detection period and the each detection period; calculates a former period deviation integration value by integrating the period deviation in a former angle interval before the top dead center; calculates a later period deviation integration value by integrating the period deviation in a later angle interval after the top dead center; and determines presence or absence of misfire in the combustion stroke based on the former period deviation integration value and the later period deviation integration value.

A fuel injection control unit includes: a first transience determination unit which determines an accelerating state when the first intake pressure differential integration value in a section including a compression stroke, an expansion stroke and an exhaust stroke is greater than a first acceleration determination threshold value; a first transient fuel injection amount calculation unit which calculates an additional fuel injection amount on the basis of the first intake pressure differential integration value; a second transience determination unit which determines an accelerating state when the second intake pressure differential integration value in a section including an intake stroke is greater than a second acceleration determination threshold value which is smaller than the first acceleration determination threshold value; and a second transient fuel injection amount calculation unit which calculates an additional fuel injection amount on the basis of the second intake pressure differential integration value.

Engine control device and engine control method

An air-fuel ratio region detection unit, including a first determination voltage higher than a target voltage value indicating the stoichiometric air-fuel ratio, and a second determination voltage lower than the target voltage value, determines that an air-fuel ratio of an engine is within a first rich region when an oxygen sensor output equals or exceeds the first determination voltage, determines that the air-fuel ratio is within a second rich region when the oxygen sensor output equals or exceeds the target voltage value but is lower than the first determination voltage, determines that the air-fuel ratio is within a second lean region when the oxygen sensor output equals or exceeds the second determination voltage but is lower than the target voltage value, and determines that the air-fuel ratio is within a first lean region when the oxygen sensor output is lower than the second determination voltage.
