Abstract: A braking force controller causes a first actuator unit to generate a target jerk when the target jerk is equal to or larger than a first jerk, causes the first actuator unit to generate the first jerk and a second actuator unit to generate a jerk obtained by subtracting the first jerk from the target jerk as an additional jerk when the target jerk is smaller than the first jerk and equal to or larger than the sum of the first jerk and a second jerk, and causes the first actuator unit to generate the first jerk and the second actuator unit to generate the second jerk as the additional jerk when the target jerk is smaller than the sum of the first jerk and the second jerk.

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 from a driver assistance device 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, the request longitudinal force controlling an actuator, and an obtaining unit that obtains, as information that indicates availability, information indicating whether traction control is executed, the availability being a controllable range of the longitudinal force, wherein the feedback controlling unit prohibits the control amount from increasing when the traction control is executed.

Abstract: A motion manager mounted on a vehicle includes a processor. The processor receives, from an application that has determined that another object will collide with the vehicle, a motion request indicating that an additional braking force is needed, when the vehicle is stopped. The processor generates an instruction value for causing a brake device to generate a greater braking force than before the motion request is received, when the motion request indicating that the additional braking force is needed is received.

Abstract: A vehicle controller includes a controlling unit. The controlling unit calculates a feedback control amount based on a deviation between a target acceleration of a vehicle and an actual acceleration of the vehicle. The controlling unit executes a feedback control of a driving device and a braking device by using the feedback control amount, such that the deviation decreases. A state in which only the driving device, of the driving device and the braking device, operates is a first state. A state in which at least the braking device, of the driving device and the braking device, operates is a second state. When switched from the first state to the second state, the controlling unit calculates the feedback control amount such that the deviation permitted in the feedback control is greater than the deviation prior to a start of switching from the first state to the second state.
