Abstract: The present invention comprises: a piston provided in a cylinder hole; a lid member which closes an opening on the other side of the cylinder hole; and elastic members and which are provided between the piston and the lid member. The elastic members and comprise a first elastic member provided on the piston side of the cylinder hole, and a second elastic member provided on the lid member side of the cylinder hole. The second elastic member has a base portion provided in line with the first elastic member, and a protruding portion protruding from the piston side end surface of the base portion. When the piston has moved in the axial direction to the lid member side, the protruding portion touches the piston, undergoing compressive deformation, and the base portion subsequently undergoes compressive deformation.

Abstract: A vehicle controller sets an upper limit request value related to an upper limit of a longitudinal acceleration of a vehicle, a lower limit request value related to a lower limit of the longitudinal acceleration, and an acceleration request value related to the longitudinal acceleration that corresponds to an amount of the operation of the vehicle. The vehicle controller sets a first arbitration request value to a greater one of the lower limit request value and the acceleration request value. The vehicle controller sets a second arbitration request value to a smaller one of the first arbitration request value and the upper limit request value. The vehicle controller sets, to a value that corresponds to the second arbitration request value, a command value sent to an actuator that operates to adjust the traveling speed.

Abstract: A vehicle motion controller includes a feedback controlling unit that executes feedback control in which a difference between a target acceleration corresponding to a request value and an actual acceleration of a vehicle is an input, thereby calculating a control amount used to reduce the difference, a request outputting unit that calculates a request longitudinal force based on the control amount and outputs the request longitudinal force to the driving and braking devices, the request longitudinal force controlling the driving and braking devices, and a determining unit that, in a case where a driver of the vehicle is operating a braking operation member, obtains a braking command value and determines that operation interference by the driver has occurred when the braking command value is less than the request value. The feedback controlling unit prohibits the control amount from increasing in a case where the operation interference has occurred.

Abstract: Provided is an electric braking device wherein a friction member is pressed, via a piston driven by an electric motor, against a rotary member that rotates integrally with a vehicle wheel, thus generating a braking force on the vehicle wheel. The electric braking device is provided with: a controller for controlling the electric motor; a rotation angle sensor for detecting a rotation angle of the electric motor; and a return mechanism for applying a return force to a piston in a direction away from the rotary member. Furthermore, the controller executes a proper/improper determination to determine whether the return mechanism is operating properly on the basis of a change in the rotation angle after conduction of electricity to the electric motor is stopped.
