Abstract: 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.

Abstract: A braking force control device includes a target acceleration calculation unit that calculates a first target acceleration based on an acquired operation amount of an accelerator pedal, a powertrain capability acquisition unit that acquires a braking force that is generable by a powertrain, and an instruction unit that instructs generation of braking forces in the powertrain and a brake. The instruction unit is configured to, when a first braking force for achieving the first target acceleration is equal to or less than the braking force that is generable by the powertrain, instruct a controller of the powertrain to generate the first braking force, and when the first braking force is larger than the braking force that is generable by the powertrain, instruct the controller of the powertrain to generate the braking force that is generable by the powertrain.

Abstract: A brake control device includes a processor that controls a brake device of a vehicle. The processor receives a first braking request indicating first braking force by the brake device which is requested from an application that implements a driver assistance function of the vehicle. The processor receives a second braking request indicating second braking force by the brake device which is requested depending on an operation amount of a brake pedal of the vehicle. The processor starts override control when the processor receives the second braking request while the processor controls the brake device in accordance with the first braking request.

Abstract: A motion manager is configured to request at least one of a plurality of actuators provided in a vehicle to move the vehicle in accordance with a kinematic plan. The actuators includes a second holding device having the holding function and being configured to execute backup control. The motion manager includes one or more processors configured to: receive information indicating the kinematic plan from a setting device; distribute, to at least one of the actuators, a motion request for the vehicle calculated by using the kinematic plan; and transmit, to the setting device, predetermined information including information indicating whether an abnormality has occurred in the holding function of the second holding device and information indicating a control status of the second holding device, and not including information for identifying a category of the second holding device.

Abstract: A control device configured to control motion of a vehicle includes a controller. The controller is configured to execute braking control that generates a braking force for decelerating the vehicle in response to a braking request. The controller is configured to release the braking force by the braking control when a predetermined condition for continuing the braking control is not satisfied, and to maintain the braking force by the braking control when the predetermined condition is satisfied, in a case where an accelerator pedal is operated during execution of the braking control.

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.
