An electric vehicle includes: a motor for traveling; an electric power storage device configured to supply and receive electric power to and from the motor; a controller configured to control the motor such that, when an accelerator is off, a braking force based on a traveling position selected from a plurality of traveling positions with different braking forces exhibited when the accelerator is off acts on the electric vehicle; and a notification unit that notifies information. the controller is configured, when the accelerator is off and a first maximum braking force output from the motor is limited more than a second maximum braking force of the traveling position selected when the accelerator is off, among the plurality of traveling positions, to cause the notification unit to notify limitation information indicating that the first maximum braking force is limited.

Electric vehicle

A vehicle control apparatus is applied to a vehicle so as to control driving of an electric motor of the vehicle. The vehicle control apparatus includes: a frequency calculation unit configured to calculate an engine pulsation frequency; a damping control content switching unit configured to switch a damping control content; a gain calculation unit configured to calculate a gain, used for a torque command for driving the electric motor; a torque calculation unit configured to calculate the torque command by multiplying the calculated gain by at least one of a torsion torque reduction component and a motor torque reduction component; a command torque determination unit configured to determine a damping control torque command; and a drive control unit configured to control the driving of the electric motor based on the damping control torque command.

Vehicle control apparatus

A parking assistance device includes a detection unit that detects a parkable area in a surrounding area of a vehicle, a route calculation unit that calculates a parking guidance route for guiding the vehicle from the current position of the vehicle to a parking target position contained in the parkable area, and a control unit that guides the vehicle to the parking target position according to the parking guidance route, completes the guidance when the vehicle has fit into the parkable area with a certain attitude and has reached the parking target position, and varies a completion extension period until the guidance of the vehicle is completed according to the stop mode of the vehicle when the vehicle has entered the parkable area with the certain attitude and the vehicle has stopped before reaching the parking target position.

Parking assistance device

A parking assistance device according to an embodiment includes a determination unit that determines, when the parallel parking of a vehicle in a parking area is assisted, whether the parking space length of a frontage that the vehicle enters in the parking area is the sum of the full length of the vehicle and a certain length or more and a control unit that performs parking assistance for the vehicle along a route in which stationary steering control is not performed at a turning position of the vehicle when the parking space length is the sum of the full length of the vehicle and the certain length or more.

Parking assistance device and parking assistance method

A vehicle control device according to an embodiment includes: a steering controller configured to control steering of a vehicle; and a controller configured to, when the vehicle is located at a first position on a travel route, instruct the steering controller to control the vehicle at a steering angle corresponding to a second position that is an advanced position from the first position in a traveling direction on the travel route.

Vehicle control device

A driving assistance device according to an embodiment includes: a target setting unit configured to set a stop target; an acquisition unit configured to acquire a position of a vehicle; and an output information control unit configured to control a display unit to display a first image that instructs a driver to stop the vehicle in a first form when the vehicle is located within a region including the stop target and display the first image in a second form different from the first form when the vehicle is located outside the region.

Driving assistance device and driving assistance system

A vehicle position detecting device includes an ECU that acquires a wheel speed of a wheel of a vehicle corresponding to rotation of the wheel, detects a skid of the wheel, calculates, when the skid is not detected, a vehicle body speed corresponding to the speed of a vehicle body of the vehicle based on the wheel speed, and corrects, in response to detection of the skid, the wheel speed based on correction information and calculates the vehicle body speed based on the corrected wheel speed. The ECU further calculates the position of the vehicle based on the vehicle body speed depending on the presence of the skid.

Vehicle position detecting device

A control system for a vehicle includes an electronic control unit. The electronic control unit is configured to acquire first information indicating a situation of the vehicle at the time when the vehicle is traveling, and set a path for guiding the vehicle to a target position on the basis of the first information such that a variation in an inertial force in a lateral direction perpendicular to a traveling direction of the vehicle is smaller than or equal to a first threshold.

Control system and control method for vehicle

A control system for a vehicle includes a steering control unit and an electronic control unit. The steering control unit is configured to control a steering angle of a wheel of the vehicle. The electronic control unit is configured to acquire a target steering angle set as a target to move the vehicle, adjust the acquired target steering angle such that the target steering angle does not exceed a first guard value determined in order to inhibit a change in the steering angle of the vehicle, larger than or equal to a first reference, output the adjusted target steering angle to the steering control unit in order for the steering control unit to control the steering angle to the adjusted target steering angle, and change the first guard value in response to a situation of the vehicle.

Control system for vehicle

A park exit assist system includes an electronic control unit. The electronic control unit is configured to, at a time of assisting in moving a vehicle parallel parked in a parking area out of the parking area, set an imaginary line at a boundary at a predetermined position on a side in a direction, which is opposite to a direction in which the vehicle is moved out of the parking area, on the basis of a position of the vehicle at a start of assisting in moving the vehicle out of the parking area, set an area beyond the imaginary line for a no-entry area, and execute control for assisting in moving the vehicle out of the parking area such that the vehicle does not enter the no-entry area.
