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.

Vehicle motion controller

A vehicle control device includes a processor. The processor calculates an instruction value of an operation request for controlling an operation of an actuator mounted on a vehicle based on a motion request from an application. The processor executes feedback control on the instruction value using a deviation between the motion request and a motion result of the vehicle that is calculated based on one of detection values of four wheel velocity sensors. The processor calculates the motion result in the feedback control based on a detection value indicating the second largest vehicle body velocity among the vehicle body velocities indicated by the detection values of the four wheel velocity sensors when the vehicle is braked.

Vehicle control device

A travel controller executes a first correction process on a request value when the vehicle is traveling on an uphill road, and executes a second correction process on the request value when the vehicle is traveling on a downhill road. The first correction process corrects the request value such that the traveling speed is higher than that in a case in which the first correction process is not executed. The second correction process corrects the request value such that the traveling speed is lower than that in a case in which the second correction process is not executed. If hard braking of the vehicle is requested during execution of the first correction process, the travel controller sets a correction amount of the request value to a lower value than that in a case in which hard braking of the vehicle is not requested.
