Abstract: A vehicle controller includes a processor configured to detect an object region including another vehicle near a vehicle from each of time series images obtained by a camera mounted on the vehicle; detect a predetermined action taken by the other vehicle, based on a trajectory of the other vehicle estimated from the object region of each image; identify the state of a signal light of the other vehicle, based on characteristics obtained from pixel values of the object region of each image; extract information indicating characteristics of an action of the other vehicle or the state of a signal light at the predetermined action taken by the other vehicle, based on the predetermined action detected in a tracking period and the state of the signal light related to the predetermined action; and predict behavior of the other vehicle, using the extracted information.

Abstract: An apparatus for object detection detects a number of lanes included in a road on which a vehicle is traveling, detects one or more surrounding vehicles positioned in surroundings of the vehicle from a surrounding image showing the surroundings of the vehicle generated by a camera mounted in the vehicle, and determines, when more surrounding vehicles than the number of lanes detected in a predetermined range at the back of the vehicle are detected alongside in a width direction of the vehicle, that a possibility that any one of the surrounding vehicles being an emergency vehicle which is allowed to travel without obeying the traveling rule of the road is higher than when more surrounding vehicles than the number of lanes are not detected alongside in a width direction of the vehicle.

Abstract: A vehicle control device has a processor configured to calculate an average speed of a vehicle traveling in a traffic lane and another vehicle in a predetermined range from the vehicle, for each of multiple traffic lanes of a traveling road on which the vehicle is traveling, as a traffic lane average speed, to determine whether the traffic lanes are congested based on the traffic lane average speed for each of the multiple traffic lanes of the traveling road and to estimate whether the traveling road as a whole is congested based on a proportion of traffic lanes of the traveling road that are congested, and to decide to drive the vehicle by automatic control when the traveling road as a whole is congested.

Abstract: A travel controller autonomously controlling travel of a vehicle, estimating an estimated arrival timing at which the vehicle is expected to arrive at a predetermined location where autonomous control can no longer be continued, starting notification of a transition demand demanding a transition of operation from the autonomous control to manual control a predetermined time period before the estimated arrival timing, ending the transition demand and the autonomous control and starting acceptance of a driving operation when a responsive motion of the driver to the transition demand is detected before the vehicle reaches the predetermined location, and ending the transition demand and the autonomous control and performing safe stopping control of acceleration, deceleration, and steering so that the vehicle stops at a safe position when the vehicle reaches the predetermined location without a responsive motion being detected.

Abstract: A control system includes a controller. The controller counts the number of driving times of a high pressure fuel pump, which is the number of reciprocating motions of a plunger based on a crank counter. The controller estimates a high pressure system fuel pressure based on the calculated number of driving times, a fuel temperature detected by a fuel temperature sensor, and a low pressure system fuel pressure detected by a low pressure system fuel pressure sensor when the high pressure system fuel pressure is not able to be acquired from a high pressure system fuel pressure sensor. The controller sets an opening period of an in-cylinder fuel injection valve based on the estimated high pressure system fuel pressure and to perform an engine start by an in-cylinder fuel injection when the high pressure system fuel pressure is not able to be acquired from the high pressure system fuel pressure sensor.

Abstract: The air-fuel ratio feedback control section updates an air-fuel ratio feedback correction value. The air-fuel ratio learning control section performs, in each of learning regions, learning of an air-fuel ratio learning value. If the air-fuel ratio feedback correction value converges to a value less than or equal to a specified value, the air-fuel ratio learning control section determines that learning of the air-fuel ratio learning value in the learning region has been completed. If it has not yet been determined that learning of the air-fuel ratio learning value has been completed in any of the learning regions, the air-fuel ratio learning control section collectively updates the air-fuel ratio learning values of all the learning regions at the time of updating the air-fuel ratio learning value through learning in any of the learning regions.

Abstract: A fuel injection control device learns a port injection learning value and a direct injection learning value separately for each of learning regions that are divided according to the engine operating state. It is assumed that a port injection learning condition and a direct injection learning condition are both satisfied in a learning region in which neither the learning of the port injection learning value nor the learning of the direct injection learning value has been completed. In such a situation, the fuel injection control device executes the port injection learning process if the ratio of the port injection amount is less than the ratio of the direct injection amount, and executes the direct injection learning process if the ratio of the direct injection amount is less than the ratio of the port injection amount.
