Abstract: The vehicle-travel control device estimates an evaluation level of the automated-driving management device from the standpoint of the vehicle-travel control device, when the vehicle is approaching a caution point indicating a point where caution needs to be exercised in driving, determines whether the vehicle-travel control device has a history of passing through the caution point with the vehicle-travel control device having received an execution prohibition instruction to prohibit execution of the travel assistance control, and when the vehicle-travel control device has received the execution prohibition instruction, and it is determined that the vehicle-travel control device does not have a history of passing through the caution point, changes an execution mode of the travel assistance control based on the evaluation level such that the travel assistance control is more likely to be executed.

Abstract: A driving assist device for a vehicle sets a a roadway area ahead of the vehicle, detects an avoidance target existing ahead of the vehicle, and executes collision avoidance control that avoids a collision between the vehicle and the avoidance target. The collision avoidance control is more likely to be executed when the avoidance target is within the roadway area than when the avoidance target is outside the roadway area. The driving assist device detects a roadway end object and a first lane marking of a first lane in which the vehicle exists. An imaginary position is a position apart from the detected position of the roadway end object toward the first lane by a constant distance. The driving assist device sets the imaginary position or the detected position of the the first lane marking as a boundary position of the roadway area based on a predetermined condition.

Abstract: A gas sensor element with suppressed response deterioration even when poisoned with S when fuel or exhaust gas contains ethanol and the ethanol content is high. The element includes a detection portion, which includes a solid electrolyte layer having a pair of electrodes on opposite sides thereof, a shielding layer defining a measurement target gas space with a porous diffusive resistance layer, and a reference gas space protective layer; a heat-generating portion stacked on the detection portion; and a porous protective layer surrounding the detection portion and heat-generating portion. The porous protective layer includes a first porous protective layer surrounding at least the porous diffusive resistance layer, and a second porous protective layer surrounding the first porous protective layer, the detection portion and the heat-generating portion. The first porous protective layer contains none of La, Ca, or Mg, while the second porous protective layer contains at least one of them.

Abstract: An ECU outputs an ignition signal and a discharge waveform control signal. An ignition device performs a closing operation of an ignition switching device while the ignition signal is input into the ignition device. The ignition device adjusts a current flowing through a primary coil to a discharge current command value determined based on the discharge waveform control signal, by performing an opening-closing operation of a control switching device in a period in which the discharge waveform control signal is input into the ignition device after an input of the ignition signal into the ignition device is stopped. The ECU sets the discharge current command value that is a command value for a discharge current of a spark plug to a higher value as a rotation speed is higher, and prolongs a duration, in which discharge controller controls the discharge current, as the rotation speed is lower.
Abstract translation: ECU输出点火信号和放电波形控制信号。 点火装置在将点火信号输入到点火装置中时进行点火开关装置的关闭动作。 点火装置通过在输入放电波形控制信号的期间内进行控制切换装置的开闭动作，将流过初级线圈的电流调整为基于放电波形控制信号而决定的放电电流指令值 在点火装置的点火信号输入停止之后进入点火装置。 ECU将作为火花塞的放电电流的指令值的放电电流指令值作为转速设定为较高值，并且将放电控制器控制放电电流的持续时间延长为转速 较低。
