摘要： An internal combustion engine control apparatus includes a cylinder pressure sensor, a driving condition detector, a reference crank angle setter, a reference cylinder pressure calculator, an air-fuel ratio estimator, and a controller. The cylinder pressure sensor detects a cylinder pressure. The driving condition detector detects a driving condition in an engine. The reference crank angle setter calculates a reference crank angle immediately before which an air-fuel mixture starts combusting in accordance with the driving condition. The reference cylinder pressure calculator calculates a reference cylinder pressure in the cylinder at the reference crank angle based on temperature characteristics of a specific-heat ratio of the air-fuel mixture under a condition. The air-fuel ratio estimator calculates an air-fuel ratio based on a pressure difference between the reference cylinder pressure and the cylinder pressure at the reference crank angle. The controller controls the engine in accordance with the air-fuel ratio.

摘要： The disclosure provides a vehicle external detection device. An imaging device and a radar device are mounted in a vehicle and configured to detect a rear lateral side of the vehicle. Detection regions of the imaging device and the radar device are overlapped with each other. The vehicle external detection device includes an imaging occlusion occurrence detection device and a correction device.

摘要： An exhaust gas purifying apparatus for an internal combustion engine, in which a NOx absorbing catalyst and a NOx concentration sensor for detecting a NOx concentration in exhaust gases of the engine, are provided in an exhaust passage of the engine. A rich spike for temporarily enriching the air-fuel ratio is performed, and an execution timing of the rich spike is determined based on a detected output from the NOx concentration sensor. Performing the rich spike is determined to be unnecessary during a reducing state period from the time the rich spike ends to the time a preset time period has elapsed, and is also determined to be unnecessary when a change tendency of the detected output is determined to be an output decreasing state where the detected output is decreasing. The execution timing of the rich spike is determined using the detected output when the change tendency is determined to be an output staying/increasing state where the detected output is staying at a constant value or increasing after the end timing of the reducing state period.

摘要： A control device includes a cylinder pressure sensor, a driving condition detector, a reference crank angle setter, a reference cylinder pressure calculator, an EGR ratio estimator, and a controller. The cylinder pressure sensor detects a cylinder pressure inside a cylinder. The driving condition detector detects a driving condition in an internal combustion engine. The reference crank angle setter calculates, according to the driving condition, a reference crank angle immediately before which mixture gas starts combusting. The reference cylinder pressure calculator calculates a reference cylinder pressure at the reference crank angle based on temperature characteristics of a heat capacity ratio of the mixture gas under a condition. The EGR ratio estimator calculates an EGR ratio based on a pressure difference between the reference cylinder pressure and the cylinder pressure at the reference crank angle. The controller controls the internal combustion engine according to the EGR ratio.
