A vehicle control device includes a route processor that generates a route from a current location position to a target position. The target position remains constant. The vehicle control device further includes a steering pattern processor that generates a target steering angle, which is a target value of a steering angle for the route, and outputs steering angle information indicating the generated target steering angle. The vehicle control device further includes a steering angle processor that corrects the steering angle information such that a transition curve section of the route includes a steering angle increasing section where the steering angle is below the target steering angle and a steering angle decreasing section where the steering angle exceeds the target steering angle. The vehicle control device further includes a steering controller that performs steering control based on the steering angle information corrected by the steering angle processor.

Vehicle control device

This vehicle control device is provided with: an environment recognition unit for recognizing the surrounding environment of a vehicle; a parking route generation unit for generating a travel route to a parking position which is determined on the basis of the recognized surrounding environment; a signal input unit to which a parking command signal is input; and a travel control unit for causing the vehicle to travel along the travel route to the parking position on the basis of the input parking command signal. The vehicle control device drives the vehicle to travel to the parking position for automatic parking while behaving differently depending on whether the parking command signal input to the signal input unit is a first parking command signal or a second parking command signal.

Vehicle automatic parking control device

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.

When there are a plurality of routes to one parking space, automatic parking cannot be performed on a route with short parking time. A route candidate generation unitchanges a reference vehicle speed and a route shape, and searches for a route from a parking start position to a parking target position. The route passage time calculation unitcalculates, for each route candidate, the time required to pass through the route based on the reference vehicle speed and the length of the route. A state switching time calculation unitcalculates, for each route candidate, the time required for switching between forward and backward movements of a vehicle, and the time required to change steering to a predetermined steering angle in a state where the vehicle is stopped. A route selection processing unitselects a specific route, for example, a route with short parking time, from a generated routes based on route passage time.

Parking assistance device

In the invention, in automatic parking, a route from a parking start position to a target parking position is calculated prior to the start of parking. However, there are cases where an external environment recognition device cannot detect an obstacle at a distant or blind spot. In such a case, smooth parking is hindered when the vehicle is actually automatically parked. In the invention, in Step Sthe vehicle is virtually moved from a parking start positionin the direction of a turning position, and a turning positionis calculated on a parking routeIn Step Sa preliminary route to a target parking positionwhen the vehicle is turned back at the turning positionis calculated. In the next Step Sit is determined whether the preliminary route can be generated, and when the preliminary route satisfies a predetermined condition, the route calculated by a candidate route calculation unitis adopted as an automatic parking route.

Unfortunately, even when a new area, which cannot be recognized from the parking start position, is detected in the surrounding area as the vehicle travels on the parking route, the new area cannot be used effectively as the parking route. In step S, when there is an area for extending the parking route in the newly detected area, the route is determined to be extensible. In step S, it is determined whether the vehicle can be parked with one turnabout without extending the route, and when it is determined that the vehicle cannot be parked with one turnabout, the process proceeds to step Sto perform the route extension process. When the posture of the vehicle at the turning point does not exceed a predetermined value in step S, the process also proceeds to step S. In step S, route information for extending the parking route from the turning point in the route information toward the newly detected available area is generated based on the route information output in step S, the surrounding area information and the own-vehicle position information output in step S

A host lane environment recognition unit acquires an operation of a target vehicle traveling in a host lane and a road environment. An adjacent lane environment recognition unit acquires operation of vehicles traveling in an adjacent lane and a road environment. A lane changeable space determination unit determines whether the host vehicle can change lanes using road environment information of the adjacent lane. A lane change control unit determines whether the target vehicle traveling in the host lane is allowed to change lanes, based on the operation of the target vehicle and the adjacent vehicle traveling in their lanes. The lane change control unit causes the host vehicle to change lanes based on determining whether the host vehicle can change lanes in the adjacent lane by the lane changeable space determination unit and whether or not the target vehicle is allowed to change lanes.

Vehicle control device and control method

A vehicle control device controls a vehicle on the basis of inter-vehicle spacing information with respect to a preceding vehicle and a trailing vehicle. The vehicle control device is equipped with: a target inter-vehicle spacing calculation unit which calculates target inter-vehicle spacing information on the basis of inter-vehicle spacing information with respect to the preceding vehicle and inter-vehicle spacing information with respect to a trailing vehicle. The vehicle control device is configured to control the speed of the vehicle such that the calculated target inter-vehicle spacing information is maintained.

Vehicle control device for maintaining inter-vehicle spacing including during merging

The present invention provides a vehicle control device in which it is possible to modify the travel trajectory of a vehicle in response to the presence of an obstruction in the vehicle perimeter. In the present invention, the vehicle control devicerecognizes the surroundings of the vehicle, detects a first branching point in a first route that is preset on a road, and in cases in which a prescribed condition is met by the presence of an obstruction detected from the recognized surroundings when the vehicle is to move along a travel trajectory that is based on at least one second route from among a plurality of second routes that branch from the first branching point, generates a virtual route which branches from the first route at a second branching point differing from the first branching point toward the selected second route, and modifies the travel trajectory on the basis of the generated virtual route.

A parking frame for which a parking route cannot be generated is excluded from selection objects by a simple determination. The parking assistance device acquires information on an entrance width of a frame entrance of the parking frame and information on a passage width of a passage, and calculates a minimum projection amount wm in a passage width direction of a vehiclefrom the parking frameto the passagewhen a vehicle corner on a front side of the vehicle in an approach direction to the parking frame and on a first side in a vehicle width direction is located at the entrance end on the first side of the parking frame in the frame width direction, and when the vehicle is disposed at a position where the vehicle side part on a second side of the vehicle in the vehicle width direction is in contact with the entrance end on the second side of the parking frame in the frame width direction. This minimum projection amount wm is a minimum passage width required for rotating the vehicle from a direction at a start of parking to a direction at a completion of parking without considering a turning radius in a space configured by the parking frame and the passage. The passage width wr is compared with the minimum projection amount wm, and when the passage width is smaller than the minimum projection amount, it is determined that the vehicle cannot be parked in the parking frame.

Achieving safety and natural automatic driving needs a control platform using intelligence (such as learning function and artificial intelligence), but it is difficult to ensure operations suited for the behavior of a vehicle by the output of intelligence. An automatic driving device according to the present invention includes a control program for inputting outside information and vehicle information, and outputting a target control value for a vehicle. The control program has a first program for generating a first target control amount on the basis of a dynamically changing algorithm (which outputs operations based on learning function or artificial intelligence), and a second program for generating a second target control amount on the basis of a prescribed algorithm (which outputs operations according to traffic rules or driving morals).

A lane change system that ensures safety is provided. This lane change system changes lanes by controlling steering in accordance with a path moving from a first lane in which the host vehicle is traveling to a second lane different from the lane in which the host vehicle is traveling, wherein the lane changing is stopped when there are any peripheral vehicles at high risk for collision in the second lane during a lane change from the first lane to the second lane.

Lane change system

A lane departure judgment apparatus is configured to detect a lane-dividing line based on image information output from an image-capturing device that acquires an image of an area outside a vehicle, and to judge whether or not departure of the vehicle from the lane-dividing line occurs based on a distance between the vehicle and the lane-dividing line, wherein when an angle of the vehicle with respect to the lane-dividing line thus detected is constant, the distance between the vehicle and the lane-dividing line to be used to judge whether or not departure of the vehicle occurs is changed according to whether the vehicle is being driven on a road having a lane-dividing width that is greater than a predetermined width or on a road having a lane-dividing width that is smaller than a predetermined width.
