摘要： An electronic suspension control apparatus of the invention is an apparatus that controls an electronic suspension having an electric motor, and under a predetermined operation condition, gradually decreases a thrust force command for the electronic suspension and performs short circuit control on the electric motor once the thrust force command falls to or below a predetermined value. The operation condition is either detection of a command giving a prior notice of stopping power supply to the electronic suspension, a short circuit command as a measure against a collision, detection of a predetermined decelerating vehicle speed, or detection, by a preview sensor, of a change in a road surface which is equal to or above a predetermined value.

摘要： An electrically powered suspension system includes: an actuator that is provided between a vehicle body and a wheel of a vehicle and generates a load for damping vibration of the vehicle body; an information acquisition part that acquires information on a sprung state amount and a road surface state; a target load calculation part that calculates a first target load related to skyhook control based on the sprung state amount and calculates a second target load related to preview control based on the road surface state; and a load control part. The target load calculation part calculates a third target load related to pitch generation control based on a target pitch angle and calculates a combined target load into which the first target load, second target load, and third target load have been combined. The load control part performs load control of the actuator using the combined target load.

摘要： A lane departure prevention assist system for a vehicle includes: a tilt angle control unit configured to control a tilt angle of a seat surface with respect to a lateral direction by driving a tilt angle changing device; a lane detection unit configured to detect a lane on a road; and a vehicle position estimation unit configured to estimate a lateral position of the vehicle in the lane. The tilt angle control unit is configured to increase the tilt angle of the seat surface with respect to the lateral direction such that, as the vehicle approaches one lateral end of an own lane, a height of the seat surface on a side near the one lateral end of the own lane becomes greater than the height of the seat surface on a side remote from the one lateral end of the own lane.

摘要： A preview road surface detection device of a vehicle of the present invention includes: a distance sensor that is disposed in a vehicle member and detects a distance to a measurement point on a road surface nearer to a front part of the vehicle, corresponding to at least a central portion of a contact patch to the road surface of a wheel of the vehicle; and a distance calculator that calculates a road surface distance from the vehicle member to the measurement point, based on a value detected by the distance sensor. A displacement of the road surface nearer to the front part of the vehicle is detected as a road surface condition. The displacement of the road surface is calculated from the road surface distance and a vehicle height of the vehicle member when the distance sensor detects the distance.

摘要： A vehicle control system includes a steering input member rotatably supported by a vehicle body, a first capacitive sensor provided on a first surface portion of the steering input member facing in one direction along a rotational center line of the steering input member, a second capacitive sensor provided on a second surface portion of the steering input member opposite to the first surface portion, and a control unit configured to control a drive unit and/or a brake unit of the vehicle according to signals from the first and second capacitive sensors. The control unit executes an acceleration control to control the drive unit to accelerate the vehicle when a prescribed signal is received from the first capacitive sensor, and to execute a deceleration control to control the drive unit and/or the brake unit to decelerate the vehicle when a prescribed signal is received from the second capacitive sensor.

摘要： A damper control apparatus for controlling a front damper at a front wheel and a rear damper at a rear wheel. The damper control apparatus includes: a preview sensor configured to detect a road surface state in front of a vehicle; a steering angle sensor configured to detect a steering angle of the vehicle; and a controller configured to control the front and rear dampers based on a detected value of the preview sensor. In response to the steering angle sensor detecting a steering angle that exceeds a predetermined steering angle threshold, the controller is configured to reduce control of the rear damper that is based on the detected value of the preview sensor.

摘要： A suspension device includes: a hydraulic damper including a rod provided with a valve for generating a hydraulic pressure when the rod is displaced between a first liquid chamber and a second liquid chamber; and an electric damper configured to electrically displace the rod by an actuator. The electric damper includes: an outer cylinder; an inner cylinder; a piston provided on the rod and configured to stroke in the inner cylinder; and a communication passage disposed inside the inner cylinder at a central portion where the piston strokes. The communication passage establishes communication between the first liquid chamber at one axial end side of the piston and the second liquid chamber at another axial end side of the piston.
