Abstract: An engine control device includes that controls an air excess rate of each of N (an integer of 2 or more) cylinders by controlling an intake air amount and a fuel injection amount of each of the N cylinders; and a determination unit for determining whether or not there is a request to switch the air excess rate controlled by ?1 to ?2 different from ?1. When an affirmative determination is made by the determination unit, the control unit controls the air excess rate such that a proportion of L combustion strokes at ?2 to consecutive K (an integer greater than N) combustion strokes increases from 0% to 100% in M (an integer greater than N) steps.

Abstract: A control device (100) executes control for accelerating or decelerating a vehicle (1) such that constant-speed travel in which the vehicle (1) travels at a set vehicle speed is performed, and such that following travel in which the vehicle follows a preceding vehicle ahead is performed.

Abstract: In the power conditioner having a step-up chopper connected to a plurality of solar cell strings, when a current flowing in the reverse direction from the normal direction due to a short circuit fault of any step-up chopper is detected, a relay is opened, and an inverter is stopped. A gate of an IGBT of the step-up chopper where a short circuit fault has occurred is turned off. Solar cell strings are controlled in a way that at least any of power, a voltage and a current input to a solar cell string is set as less than or equal to a predetermined threshold value.

Abstract: There is provided a collision avoidance assist apparatus that includes an object detection sensor that detects a relative speed between a vehicle and an object ahead, a brake unit that brakes the vehicle so as to avoid collision with the object ahead, and a control unit that sets a set braking time that will be taken for the relative speed to reach zero based on set deceleration determined depending on a braking ability of the vehicle, and controls the brake unit such that the braking of the vehicle is continued over the set braking time.

Abstract: A collision determination device includes: a radar detection unit that detects an object around a vehicle using a radar wave; an image detection unit that captures an image of the surroundings of the vehicle and detects the object using the captured image; and a collision determination unit that determines a collision between the vehicle and the object on the basis of a composite target which is generated using a detection result of the radar detection unit and a detection result of the image detection unit. When the object is detected by the radar detection unit and the image detection unit after being detected only by the image detection unit of the radar detection unit and the image detection unit, the collision determination unit performs the collision determination, preferentially using the detection result of the image detection unit over the detection result of the radar detection unit.

Abstract: A collision determination device includes: a radar detection unit that detects an object in front of a vehicle using a radar wave; an image detection unit that captures an image in front of the vehicle and detects the object using the captured image; and a collision determination unit that determines a collision between the vehicle and the object based on a composite target which is generated using a detection result of the radar detection unit and a detection result of the image detection unit. The collision determination unit performs collision determination on the basis of the detection result of the image detection unit, instead of the collision determination based on the composite target, when it is determined that the object cannot be detected by the radar detection unit and can be detected by the image detection unit and the object is stationary in a traveling direction of the vehicle.
