A vehicle parking control device has a processor and a memory to control the vehicle from a starting to a target parking position. The vehicle control device includes an obstacle detection unit detecting obstacles around the vehicle, a travelable area setting unit setting an area where the vehicle can travel based on a position of the obstacles, and sets the target parking position in the travelable area, a route generation unit calculating a travel route to the target parking position in the travelable area, and a parking execution unit that causes the vehicle to travel toward the target parking position on the basis of the travel route. The route generation unit generates a route from a parking start position to the target parking position, and corrects a distance of the section to a predetermined distance when the distance of the section is less than the predetermined distance.

A parking assist device capable of parking assistance that ensures high accuracy of a parking location is provided. A parking assist device that assists in performing an operation of parking a vehicle includes a parking-allowing location calculation unit that before the vehicle stops at a parking-allowing location, calculates and updates the parking-allowing location a plurality of times, and a parking route calculation unit that calculates a parking route. The parking route calculation unit sets a minimum turning radius for calculating the parking route, based on the amount of a shift between the parking-allowing location not updated and the parking-allowing location having been updated, and calculates the parking route, using the minimum turning radius. The minimum turning radius is set larger than the minimum value of a turning radius unique to the vehicle.

The present invention realizes a vehicle control device that, even when power characteristics of a power generation device and a power transmission device changes, senses degradation of vehicle components, corrects a drive instruction to the power transmission device, and is thereby capable of stabilizing vehicle behavior over a long term. The present invention, in a predetermined vehicle environment state, measures fluctuation in drive power and acceleration in a transient region by using vehicle behavior sensors, performs comparison with a reference fluctuation, and thereby senses degradation of vehicle components. The drive instruction to the transmission-side is corrected in accordance with the degradation of vehicle components that is sensed. Thus, it is possible to stabilize vehicle behavior (performance) over a long term even when, during automated driving, the power characteristics of the drive power source and the transmissionchange due to factors such as time degradation of vehicle components.

A parking support device is provided which, when calculating a parking route followed by a host vehicle, calculates the parking route based on the reliability of obstacle information acquired by a sensor mounted on the host vehicle, thereby improving the convenience of a driver of the host vehicle. A parking support deviceincludes an obstacle information analysis unitthat recognizes an external world from external world information detected by a cameraand a sonarthat acquire the external world information, and a parking route calculation unitthat calculates a parking route of a host vehiclebased on information on an obstacle in the external world recognized by the obstacle information analysis unit, and the parking route calculation unitsets a distance between the obstacle and the host vehiclein the parking route according to a degree of reliability of information on the obstacle.

Parking assistance device

When one sensors fails and thus malfunctions during automatic parking of a vehicle, only the other sensor functions. Accordingly, depending on the behavior of the vehicle, the detection characteristics of the other sensor cause degradation in recognition of the vehicle, hindering the automatic parking from being continued. In processing S, a determination is made whether or not an external recognition device, such as a camera or sonar, malfunctions. In processing S, based on the determination on malfunction of the external recognition device, a determination is made whether or not to restrict vehicle speed or to restrict a path, with reference to restriction information for parking control. The restriction information for parking control provides information for restricting the vehicle speed in accordance with the malfunction of the camera, and for restricting the path in accordance with the malfunction of the sonar. Next, in processing S, a determination is made whether or not the automatic parking is in progress. When the automatic parking is in progress, the process proceeds to processing Swhere vehicle speed control or the like is performed for the automatic parking in accordance with the malfunction of the external recognition device.

Parking assistance apparatus

The present driving assistance apparatus assists driving from a vehicle stop state in a predetermined area. The apparatus acquires outside world information from the surroundings of a vehicle, detects a place and position to which the vehicle can move, detects a position of the vehicle, calculates a movement route when the vehicle moves in a predetermined direction by automatic driving from a vehicle stop state in a predetermined area, and determines a safety confirmation position at which the driver can visually confirm a surrounding traveling environment on the movement route. The route is calculated based on the outside world information and the position of vehicle. The driving assistance apparatus reduces a speed of the vehicle to a predetermined speed or less so that the driver can visually confirm the surrounding traveling environment at the safety confirmation position.

Driving assistance apparatus and driving assistance method

The present invention provides a parking assist apparatus capable of improving convenience when a passenger of a vehicle gets on and off. According to the present invention, the parking assistance apparatus acquires information on parking candidate frames, and where an own vehicle can park, from a front camera, a right camera, a rear camera, and a left camera configured to acquire information on a surrounding environment of the own vehicle, and from surrounding environment information acquired by these cameras. The parking assistance apparatus detects surrounding environment information and of the parking candidate frames, and from the surrounding environment information and information on the parking candidate frames, and determines a target parking position where the own vehicle parks based on the information on the parking candidate frames, the surrounding environment information, and the preference information related to getting on and off of a passenger who rides on the own vehicle.

In control device of an internal combustion engine, for each first period, a calculation unit calculates number of fuel injections within one combustion cycle and fuel injection rate. For first period, a first storage unit stores number of fuel injections and fuel injection rate of calculation unit. For each second period, a reference unit refers to the number of fuel injections and fuel injection rate stored by the first storage unit. A second storage unit stores for an interval, from the start time of the first fuel injection until start of the last fuel injection of at least one combustion cycle, the number of fuel injections and fuel injection rate referred to by reference unit. A control unit controls a fuel injection valve so that fuel is injected in accordance with the number of fuel injections fuel injection rate stored by second storage unit.

Control device of internal combustion engine

A terminal connecting-and-fixing structure capable of ensuring the connection between the terminal and the bus bar even in the case of loose of the bolt and suppressing increase in the contact resistance, thereby preventing poorness of the conduction, is provided. A terminal connecting-and-fixing structure comprises a bus barhaving a plate-like shape, a boltpenetrating the bus bar, and a nuttightened by the bolt, and a terminalmounted on the bolt, wherein the terminaland the bus baris connected and fixed by fastening the nutto the bolt, and wherein the bus barhas a concave portion, and the terminaland the bus baris connected and fixed by fastening the nutto the boltwhile an end portion of the terminalis press-fitted in the concave portion
