A vehicle integrated control device improves ride comfort and prevents the onset of motion sickness. The vehicle integrated control device acquires a target momentum of a control axis related to a driving task of the vehicle and generates a first motion parameter and a second motion parameter different from the first motion parameter that is based on the first motion parameter to optimize a sensitivity index. A limit generation unit generates a motion limit amount of the second motion parameter based on the first motion parameter and an operation range of an actuator, a final target generation unit that corrects the second motion parameter based on the motion limit amount, and an operation amount assignment unit that determines an operation amount of an actuator based on the first motion parameter and the second motion parameter corrected by the final target generation unit.

Vehicle integrated control device and vehicle integrated control method

The present invention provides a vehicle motion control device capable of reducing vibration generated in a running vehicle and suppressing the occurrence of an unstable behavior of the vehicle. A vehicle motion control device that controls a motion of a vehicle includes an operation management unit that generates traveling status information of the vehicle, a traveling track generation unit that generates a traveling track of the vehicle based on the traveling status information, and a travel control unit that controls driving, braking, and steering of the vehicle based on the traveling track. The traveling track generation unit includes a course planning unit that generates a target course based on the traveling status information and a speed planning unit that plans a target speed by calculating a longitudinal acceleration and a lateral acceleration whose composite acceleration has one peak when the vehicle travels on each curve in the target course.

Vehicle motion control device and vehicle motion control method

A vehicle integrated-control device generates internal commands that supplement insufficient external commands in an environment where external commands are insufficient and that integrally controls each actuator to improve the operational feeling of the driver and occupant ride comfort. The vehicle integrated-control device integrally controls actuators mounted in a vehicle to control the vehicle using six control axes which are front-rear, left-right, up-down, roll, pitch, and yaw control axes, and comprises a command value acquisition unit that acquires an external command corresponding to at least one and not more than six control axes for realizing a desired driving operation; a command value supplementation unit that, based on the external command, generates an internal command corresponding to a control axis other than the control axes corresponding to the external command; and an operation amount control distribution unit that controls the plurality of actuators based on the external command and the internal command.

Vehicle integrated-control device and vehicle integrated-control method

A vehicle motion control device generates a travel route where behavior of a vehicle traveling on a curve is small and comfortable ride is achieved even when the vehicle travels on a continuous curve. The control device includes a travel track generation unit that generates, based on information on a curvature of a first curve on a lane existing in a traveling direction of a vehicle and a curvature of a second curve connected to the first curve, a travel route by setting curvature of the travel route at a time of traveling on a curve having a smaller curvature between the first and second curves to be larger than the curvature of the curve and setting a curvature of the travel route at a time of traveling on a curve having a larger curvature between the first and second curves to be smaller than the curvature of the curve.

Object detection device, travel control system, and travel control method

An object position detection device includes a first distance detection unit detecting a distance of an object from images, a first position detection unit detecting a position of the object based on the distance, a processing area which contains the object detected by the first distance detection unit in images, a second position detection unit that detects a position of the object in the processing area, a second distance detection unit that detects a distance of the object based on the position of the object detected by the second position detection unit, a unit that detects an orientation of the object based on the position of the object detected by the second position detection unit, and a determination unit that determines the distance and the position of the object in accordance with information of detections executed by the first and the second distance detection units, and the orientation detection unit.

Object position detection device, travel control system, and travel control method

An electric braking apparatus which first moves a piston in a detaching direction or passes a current to move the piston in the detaching direction in order to detect a pad contacting position. Furthermore, while the piston moves in the detaching direction, pad non-contact judgment is performed. After a pad non-contact state is confirmed, the piston is moved in a pressing direction to detect the pad contacting position. When the piston does not move in the detaching direction, it is judged that a parking brake has an ON-state, and it is waited until a host system instructs parking brake release.

Electric braking apparatus and vehicle having thereof

After cruise control is restored by an accelerating operation, the driver set speed is changed according to the displacement of the accelerator pedal. It becomes possible to reduce the driver set speed due to release of the accelerator pedal, that is, the vehicle can be decelerated by the engine. Even if the cruise control is restored, the cruise control is not conducted and the vehicle can be decelerated by the engine if the driver wants to decelerate the vehicle by the release of the accelerator pedal.
