A vehicle control system is provided which includes a travel controller working to execute a coasting mode to cut transmission of drive power, as produced by an engine to a drive wheel of the vehicle when a given execution condition is encountered while the vehicle is traveling. The travel controller determines a threshold value, as used for comparison with a position of an accelerator, based on the speed of the vehicle. When the position of the accelerator is determined to be smaller than the threshold value, the travel controller executes the coasting mode. This improves the fuel economy in the vehicle without sacrificing traveling of the vehicle according to a drivers operation on the accelerator.

An apparatus for controlling an own vehicle that is a vehicle carrying the apparatus in a proper manner taking into account drivers driving maneuver tendencies is provided. The apparatus acquires travel situation information including target information regarding a target or targets around the own vehicle and travel information regarding the own vehicle, and if the travel situation information meets a prescribed travel condition, acquires driving maneuver information regarding a driving maneuver performed by the driver of the own vehicle. The apparatus stores, as a learned value, the driving maneuver information acquired by the second information acquirer in association with the prescribed travel condition, and performs automatic driving control based on the learned value stored by the learner in association with the prescribed travel condition met by the travel situation information currently acquired by the first information acquirer.

A steering controller that controls a motor to output an assist torque to steer a steering member, including a steer property calculator calculating a steer state quantity that is an index of a steering state indicating one of (i) a steer-away state, (ii) a steer-back state, or (iii) a stay-still state, an adjusted torque calculator calculating an adjusted torque based on the steer state quantity, and an instruction value calculator calculating an assist torque instruction that is an instruction value regarding a drive of the motor by using the adjusted torque. In such manner, the steer state quantity, the steer-back operation, the stay-still operation of a steering wheel, and the adjusted torque are appropriately calculated, thereby enabling an appropriate adjustment of a steering feel.

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.

A catalytic conversion characteristic of a catalyst, which indicates a relationship between an air-to-fuel ratio and a catalytic conversion efficiency of the catalyst, includes a second air-to-fuel ratio point, which is a point of starting an outflow of NOx from the catalyst and is located on a rich side of a first air-to-fuel ratio point that forms an equilibrium point for a rich component and oxygen. A constant current circuit, which induces a flow of an electric current from an exhaust side electrode to an atmosphere side electrode through a solid electrolyte layer in a sensor element, is connected to the sensor element. A microcomputer controls a current value of the electric current, which is induced by the constant current circuit, based on a difference between the first air-to-fuel ratio point and the second air-to-fuel ratio point at the catalyst.

An A/F sensor element includes a substrate made of an insulating ceramic having a bottomed cylindrical shape, an electrolyte part made of a solid electrolyte, and a pair of electrode portions. The electrolyte part is embedded in at least a portion of the side wall of the substrate. The A/F sensor element is used by inserting a rod-like heater in the substrate having the bottomed cylindrical shape. The substrate is formed of the insulating ceramic at a contact position to the heater within the substrate. In a manufacturing of the substrate, a molded body having a space for a forming position of the electrolyte part is formed by using substrate-forming clay, and then the molded body is molded by filling electrolyte-forming clay into the space.

The present disclosure provides a suction filter that filters a fuel inside a fuel tank of a vehicle. The suction filter includes a filter element, a partitioning wall element, a passage element, and an open/close valve. The filter element is disposed in and exposed inside of the fuel tank. The filter element filters a stored fuel stored in the fuel tank. The partitioning wall element is arranged in the inside space to divide the inside space into a first space and a second space that is lower than the first space. The inlet to take in the filtered fuel is open in the second space. The passage element defines an inflow opening open in the first space, an outflow opening to which a negative suction pressure is applied through the inlet, and a flow passage through which the filtered fuel flows. The open/close valve closes the inflow opening when a liquid level of the filtered fuel is above the partitioning wall element and that closes the inflow opening when the liquid level is below the partitioning wall element.

A valve device includes: a ball valve (1) having a ball face (1a) shaped in a convex spherical surface; and a valve seat (2) having a seat face (2a) shaped in a concave spherical surface. The seat face is pressed onto the ball face. The ball valve is rotated to open a valve by communicating a valve opening (1 b) defined in the ball valve and a seat opening (2b) defined in the valve seat with each other, and to close the valve by stop the communication. A diameter of the seat opening 2 is smaller than a diameter of the valve opening 1. A curvature radius of the ball face R1 is smaller than or equal to a curvature radius of the seat face is R2.

An image display device for displaying an image around a vehicle executes a sight-line transformation of the captured view image around the vehicle and generates a captured birds eye view image having a sight-line viewed from above the vehicle. The device acquires movement information representing a movement amount of the vehicle, and extracts, based on the movement information, a history image corresponding to a dead angle area of the in-vehicle camera from the captured birds eye view image generated before the vehicle reached a current location. The device displays the history image and the captured birds eye view image in a display window. When detecting an image of foreign matter adhered on the in-vehicle camera in the history image, the device extracts a partial image region without the foreign matter image from another captured birds eye view image, and uses the extracted image as the history image.
