摘要： A control apparatus for a vehicle provided with (i) a power source, (ii) drive wheels and (iii) a fluid transmission device disposed between the power source and the drive wheels and including a lockup clutch to which a fluid pressure is supplied. A feedback control is executed for correcting a command value of the fluid pressure by a correction amount such that an actual value of a slip amount of the lockup clutch becomes substantially equal to the target value of the slip amount in a slip control. When the actual value has been converged into a given range with respect to the target value, the correction amount is obtained, and the command value for a next execution of the slip control is corrected by learning with use of the obtained correction amount. The given range is set depending on the target value of the slip amount.

摘要： 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.
